7x57 Type B Oberndorf style build
      #343495 - 22/07/20 08:45 PM

Been obsessing over Type Bs for a long time. I’ve decided to admit I’ll never own one (any time soon at least). So I’m Going to attempt to build a look a like. I’m starting with a 1937 Portuguese contract receiver (oberndorf marked). I’ll not be D&Ting it for a scope but may D&T the rear ring for a receiver sight, not 100% on that though...

I’m Having Cameron Hatcher copy a Type A stock but leave me enough meat to form a forend schnabel (he doesn’t have a type B and as far as I can tell this is the main difference?). I’ll post more details as I go but my first point I need help with is the barrel profile. Grant Swan (of Allan Swan Barrels) is making me the 28” 7x57 barrel in 1:9 and throating it deep for a 175gr RN seated out to use up the 98 magazine space. However he’s waiting on me to provide barrel contour dimensions. He could use a Lother Walther Type E profile but as far as I know this is more of a type A profile, and i’d prefer to keep it more Type B. From what I can tell (google picture mostly) type Bs predominantly had a military style Knox, followed by a step, then the rear sight sleeve. Was the sight sleeve combined with a second step, or was the sleeve the step? I guess in a pinch I could have a second step and solder a NECG sight base on... some Type Bs seem to have a more modern style Knox and step less profile though, what was behind the difference?

Anyway my most pressing question is - is there anywhere I couldn’t find an original Type B 28” barrel profile? Or would someone’s who has one be able to measure the key dimensions? I would very much appreciate any help!

Wedgie,
I'm not sure if you could use this as a reference based on the Mauser action itself, but if blown up large enough you may be able to scale up from there?

Type B
https://www.gunsinternational.com/guns-f...un_id=101465426

Type A
https://www.gunsinternational.com/guns-f...un_id=101479526

Mauser PreWar?
https://www.gunsinternational.com/guns-f...un_id=101477553

Also added info from Lothar-Walther Barrels
Mauser types Page 17
https://www.lothar-walther.de/media/pdf/8d/04/37/LW-brochure-19.pdf

Hopefully Lancaster or Kudae might be able to assist in this regard as to which 'profile' matches & then go from there
Fingers crossed for you matey
Certainly a worthy project!

In page 124 of Jon Speed's "Original Oberndorf Sporting Rifles" there is a factory drawing of the Type E (English) barrel profile used on rifles made up in calibers from .250" to .350". It's pretty dim and I'm not sure it would scan legibly, but I am willing to give it a try if you will let me have your email address.

Jon Speed says 6.5" to .404" in the text, but the label on the drawing clearly says ".250-.350 u. 6.5-9" The barrel length is given as 600 mm (23.6").

Thanks for the links - the first one is what I’m after I think. Scaling from a photo would be a bit tricky To do accurately, especially as the photos pixelate quickly when blown up. Might be a good one to fall back on though...

The LW profiles on page 17 are good, however the ones that interest me most are the type E - regular and lightweight. But pretty sure these are type A profiles

thanks a lot for the offer - but I’m pretty sure he’s referring to type A (which was Oberndorf’s English style - Type B was their “continental”). If I can’t find a Type B profile I might take you up on that though! It’s slightly odd that there seems to be a lot more info and options out there for Type A rifles than Type B - although just going on auction and sale numbers Type B seem the more common rifle nowadays...

thanks for those Rothhammer, the info page about the Mauser details is especially interesting. I’m still trying to decide on sights. The cocking piece peeps aren’t very cool looking there’s no doubt. However, I associate them more with rigby than type Bs, and to get them accurate I’d have to do a lot of work tightening up the cocking piece, not to mention the fitting and initial purchase price.

I’m in two minds about a receiver peep sight - on the one hand they’re a very good sight (have an old steel Lyman 66 on a lever action and it’s excellent) - accurate, easily adjustable and sort of period. But they’re also very American, and as far as I can tell never an original Mauser fitment. But maybe I could relent And allow myself a modern alteration... a Lyman 35 would be amazing but would probably cost as much as the stock and barrel combined.

I am sure I want an original style barrel mounted rear sight base those - even if I end up not mounting sight I want the option. Partly for looks, but also with the 28” barrel I’d Ben getting a good sight radius so might consider it. Was the rear sight base a sleeve like a military one on a type B? And can you modify a military one to match? Was the barrel diameter the same in that spot? Can a military tangent sight be made to look like a type B tangent sight?

Don't worry about a little wiggle with a cocking piece sight. The aperture has to move 8 thousandths with a sight radius that long, to shift the bullet impact 1" at 100 yards. And .008" is a lot of wiggle.
The cocking piece and sear engagement surfaces will tend to go back to the same spot anyway, once everything wears together.
You can make a notch like Rigby's did, but it's not really necessary.I have a rifle that shoots 2" all day long, and it's not done.

mate that is fantastic thanks a lot! Sounds like a perfect rifle too... if it’s too much faff attaching photos I can PM you my mobile number?

out of interest is it this barrel style?


Or this?

that makes my decision slightly harder - I’d sort of discounted them! Definitely still interested now though, is anyone making new ones? What are they worth normally?

I'm glad you found the images to be of use. The 'options' page shows that pre - WW2 buyers had several factory installed options available to them across model lines. In other words a sight that may initially seem 'improper' may well have been available as a factory installed 'cost option' when new. Surely images of Mauser, ZUM, and other European catalogs and advertisements of the day would provide more examples.

Regarding your type B sight/ military/ sleeve/ modification question, I don't know.
I have but cursory knowledge of Mausers, member Kuduae would likely be an excellent source of accurate information on the topic. Hopefully he'll 'weigh in'.

For highly detailed, high resolution photos that will enlarge well, look through Dorleac's archives and / or contact (member) Joel Dorleac. He is an expert restorer of Continental firearms and certainly knows his stuff.

My 1924 proofed Mannlicher Schoenauer M1910 Take Down (yes, I know, it's Austrian) wears a factory installed 'pop up' tang sight of the type that was also available (factory installed?) on Mausers:



I'd love to get hold of a Sportarget. Watch Ebay and other auction listings for Lyman 35.

Lyman 35 parts: Ebay 35 parts

Sportarget with different mount: Ebay Sportarget

Pricey Lyman 35: Pricey

This looks like the model Kuduae modified in his thread: PH Sportarget

Did you notice the "half round, half octagon barrel with raised matted solid rib" on the Model 610 image?
"Supplied regularly only in caliber .30 - 06 U.S. but can be had on special order in any Mauser caliber."

Wedgetail, it has the lower barrel style with fixed rear sight. I'll have a crack at posting some photos but never seem to have much luck (your phone No. is probably a good back-up). Great hunting rifle. Definitely likes German ammunition (RWS & Geco) with heavier projectiles. Also really likes the older style Win Super-X with 175 gr RN but these tend to punch thru Fallow without opening up.

Here is a Dorleac restored 7X64 'Spezial Luxusmodell' Model B with half octagon barrel, Mauser factory engraving, ... circa 1940: Luxus B

Another Dorleac Model B, this in 9X57 and ca. 1913: Pre WW1 B

Type B in 10.75X68: Big B

Type B, 8X60S: 8X60S B

If you look through the rifles in Dorleac's "Manufacturing in Progress" section you'll see that their stock work is blueprinted. Perhaps he'd share details and information from Mauser B's that he has restocked?

Yes Dorleac certainly does stunning work and hasn’t an enviable collection. Thanks for all the links. Does his site have an English section? I certainly wouldn’t mind picking his brain!

Ok chasing a little more advice - When cutting the barrel threads, the general consensus is to make the tenon the correct length so the inner C ring and outer leading edge contact their respective surfaces at the same time, maybe a thou or two one way depending on who you speak to. HOWEVER, these model Bs (as spud’s diagram shows) are like the military barrels in that their shoulder OD is essentially the same as the thread diameter. Meaning there is no shoulder to seat against. In general, the inner C ring isn’t 100% square (mine is 0.004” out cf the leading edge, which is 0.002” out). It seems unusual for people to lap the inner C ring, but not unheard of.

So, what is the standard for installing k98 or model B type barrels that have no shoulder? Do you lap the inner C ring to be 100% square? Do you not worry about 0.002”? Do I try and obtain (or make) a C ring lapping tool? Other option is I could get the shoulder say 0.050” - 0.100” wider to give it a shoulder - wouldn’t probably be overly noticeable. Then I could cut the tenon say 0.002” short and have most of the bearing surface on the (easily squared) leading edge)? I won’t be scoping this rifle, will the difference be noticeable? I doubt the inner rings wear, so I assume they wouldn’t have minded the 0.002” discrepancy at the oberndorf factory.

Couple more questions on originality: did Type Bs eve have the slab side panels in the stock either side of the action? I’m thinking these were mostly done by the independent German gun makers, but feel I have seen pictures of a type B with them. Also were they mostly an earlier feature?

And trigger guard bows - did the Type Bs ever have the shotgun style, or was that purely independents again? I read a post where someone claims they did but have never seen it. I have a bottom metal with DSTs inletted but has a shotgun trigger bow fitted. I’m thinking of grafting a military one on and shaping it back a bit. Unless someone has a bottom metal with DST inletted and a solid bow they’d like to swap?

Early Bs often did have flat panels on the stock as the two pictures show above with the rounded edge at the rear and no corresponding edge at the front.
I’m not certain if Mauser offered a shotgun style trigger guard on any of their cataloged models. I don’t think they did.

i think this is the conclusion I’m coming to. Damn. So had they completely done away with slabs by say the 1930s? And did oberndorf never produce “full” slabs?

Thanks for the links Rothhammer. Interestingly that first one with the full slab sides also has a shotgun trigger bow... although it’s not a very original looking rifle so maybe that bits changed. I do like the stock though. In fact I think I like slab sides, just trying to decide if I like them enough to deviate from my initial desire of creating as close to an original as I realistically can in terms of style - my action is marked 1937

Hey fellas, there’s a slight misunderstanding going on here. The above .270 rifle is not an Oberndorf proper, that’s a prewar JP Sauer small ring with the typical trigger guard as seen on these. It’s also not a shotgun style per se, simply an enlarged forging of the typical Oberndorf guard, there is no tang extending past the rear action screw or anything on these. Also note the simple straight line border engraved and matted top of receiver, this is standard on a Sauer. Sauer’s styling on Mauser action rifles was basically unchanged on their “normal” production models from at least 1897 until the war. The earliest I’ve seen was a three digit serial on a transitional 1897 action, it’s pre 1898 of course but has many of the features already. I believe I actually saw that rifle on this forum somewhere.

I largely collect Sauer so if anyone would like pictures of this trigger guard or any other details let me know as I have some on hand. This trigger guard was pretty much standard at Sauer until roughly the early 1930’s it appears, after which the internal bow release lever and converted “standard” Mauser 98 pattern trigger guards show up on them. This particular pattern I do not have yet but am on the hunt for! The one I have not seen and assume will not, is the typical Oberndorf pattern of guard as used on most of their models. Neat project by the way!

Thanks for the links Rothhammer. Interestingly that first one with the full slab sides also has a shotgun trigger bow... although it’s not a very original looking rifle so maybe that bits changed. I do like the stock though. In fact I think I like slab sides, just trying to decide if I like them enough to deviate from my initial desire of creating as close to an original as I realistically can in terms of style - my action is marked 1937




I was going a whole different way with this, but it appears that the 'full slab sides' are almost exclusively (?) seen on 'Haenel Mannlichers' such as their sporting version of Gewehr 88 (which they were producing under contract) and its descendants, the Haenel Modell 1900 and 1909. Link: Haenel
Searches of 'Haenel Mauser' end up with Gewehr 88 models in Mauser chamberings and I find very few 'slab sided' mousies.



Even so, it's entirely plausible to think that someone of that time (1937) may have crafted, or ordered to be built by a guild shop, a'custom' Mauser that varied considerably from the Mauser factory styles. Perhaps someone could have harbored a soft spot in their heart for a 'Mannlicher Haenel' they had previously owned and now (1937) wanted to have a stalking rifle of that style yet preferred the Mauser 98 action or available chamberings? Not 'Mauser original', but 'period aftermarket correct'?

Here is a page from the ol' '39 Stoeger offering stutzen stocks to spiff up WW1 surplus military rifles for do it yourselfers in the U.S., or one could send the rifle to Stoeger and have them do the conversion:

They are standard at Sauer too, all of mine have it and every example I’ve seen has as well. It’s very popular and common in Suhl, many makers there had it as their standard stock pattern, Simson, Kettner etc. The example above is without a doubt Sauer. Haenel didn’t make many Mausers but I’ve seen 2 or 3 examples and they too have the typical stock pattern of the time.

Absolutely!
Even Westley Richards offered Mauser '98s with slab sided stocking.
Very much a German, or even broader European style but even the English weren't averse to satisfying a customer request.

Hey fellas, there’s a slight misunderstanding going on here. The above .270 rifle is not an Oberndorf proper, that’s a prewar JP Sauer small ring with the typical trigger guard as seen on these.




Apologies if that was me.

I'm really not at all well versed on Mauser variants.

No problem at all sir, there’s always something to learn, that’s what makes these old guns so interesting. I find myself quite lost on topics outside of Mauser very quickly!

Now that Kettner you dug up.. I really like that! I’m a sucker for a Mauser Stützen, I have a Sauer very similar to it.

I’m really curious to see what direction the OP decides to go, it would be very hard for me to nail one down, I have at least a dozen Mausers ideas I’d have to sort though!

It’s also not a shotgun style per se, simply an enlarged forging of the typical Oberndorf guard, there is no tang extending past the rear action screw or anything on these...

I largely collect Sauer so if anyone would like pictures of this trigger guard or any other details let me know as I have some on hand. This trigger guard was pretty much standard at Sauer until roughly the early 1930’s it appears, after which the internal bow release lever and converted “standard” Mauser 98 pattern trigger guards show up on them. This particular pattern I do not have yet but am on the hunt for! The one I have not seen and assume will not, is the typical Oberndorf pattern of guard as used on most of their models. Neat project by the way!


thanks for the info - I’m glad you corrected me. Although a i was writing it I had a feeling I wasn’t right in saying it’s a shotgun guard, what I should have said was definitely not regular oberndorf one. Very nice all the same. I do plan on grafting a military bow on and co contouring it like a DST oberndord bow though - you wouldn’t have any dimensions to help me would you?

I like your thinking! Yes it’s a very good point - and not entirely unrealistic too. My main reason for wanting to build a copy is that I love the look of them, I’m never going to be trying to pass it off as an original so might as well put what I like on it anyway. Although I making it a Type B original As I can gives me bit of a tickle too...

A final bit of info I’m chasing for the barrel though - muzzle diameter. Spud303’s MD is 0.59”, but it’s a 24”. Continuing that taper with a 28” barrel gives a MD of 0.55”, a while mm less and something that’s more like a featherweight diameter. Should I adjust the taper so it’s 0.59” at the 28” muzzle? What would a 28” oberndorf have had?

To be honest I am having problems deciding on quite a few details that could go either way. It took me a while to work exactly what I liked about classic sporters. I thought I had it fully nailed on a 100% Type B, then Cameron Hatcher made me aware of Plezier Mausers and that threw me a bit and gave me the side panel bug... I’ll try and do a bit of a progress report early next week I think

Those last three are beautiful, and shows the classic panels I like.

I’m sure some people like them, but these westley Richards aren’t so much to my taste - way Over stated And the lines just don’t work IMO

That particular WR is very heavily embellished, of course, and has the extended magazine for the '.425 Bore' cartridge. I included it as an example of WR with 'slab sided' stock.

Some of their other offerings are quite lovely. They did put out some handsome adverts:

Sure - they certainly did, and I know you were only using it as an example of other side panels! It just struck a chord with with me not liking overstated gun art (or any art for that matter)...

Ok bit of a progress report. I’ve now got a couple of receivers to choose from, one gas less pitting than the other but still not 100%. I got it first, found the LH race was bent in a little causing the bolt to bind. I exchanged it for a straight one (pictured) but it has more pitting. I decided I didn’t like the pitting so the seller sent the other one back. A couple of minutes with the press and the race is now perfect and functions a1.







I was originally planning on using the vz24 bolt I had but decided I liked the low scope handle with checkered bottom and thought it would be a shame to break up a good action anyway. So I got another unmatched bolt from Harry’s Mausers. I told him I was building a custom and he sent me a virgin bolt - about the chrispest least molested bolt I’ve seen out side of a brand new rifle! Not sure whether to fit a Talley bolt handle or make one from bar stock. I’ve heard mixed reviews about Talley handles authenticity of shape? If I find myself having heaps of time I’ll make it but will need to hassle someone for handle dimensions







I lucked out on a new DST inletted into a bottom metal with lever floor plate release for cheap. I’ll need to hinge the floor plate and make the kicker - I’ve got a spare trigger and tracing of a kicker. I’ll have to graft a military trigger bow on and recontour. Unless someone has a solid bow’d DST’d bottom metal they want to swap with a shotgun style one?





Spud303 is very kindly sending me an original tangent sight. I’ve discovered Argentines have the same sight sleeve ID (~0.76”) so am hoping to form one into a base to suit (has this been done before? Any other ideas - Spanish Mauser maybe?). Pics when it arrives...

So I’m having dark thoughts... what are people’s views on scrubbing? I’m considering scrubbing the more pitted receiver. There are three reasons I’m thinking about.

1- the pitting, it’s not very deep, and mostly below the wood line but is there none the less. I’d prefer it if it were clean.
2- the nazi proofs. I don’t like nazis, and their presence (all four of them) makes me marginally uncomfortable. I thought I was ok with it but I’m still on the fence.
3- I’ve always like the idea of an action made for sporting use rather than a recycled military one. Hence the desire to copy a Type B. Although that’s exactly what’s happening here, I can at least pretend to myself this isn’t the case... exactly like what BRNO did with their Bo98 sporters, and Voere. I also have no ties to anyone or anything Portuguese.

I’m not worried about strength, nothings that deep. I feel guilty removing the nice crest, but in reality it’s a pitted bare receiver - not exactly collector value. Or I just use the other (nicer) one... thoughts?

Wedgie,
I've heard of micro-welding to repair pits etc - not sure who does it here, but it may be an option for you!
As to the crest, perhaps getting it engraved to reinstate back to original?

Wedgie:
I had a stunning Orion .500 Jeffery in my gunsafe for a short while, made on a Portuguese Mauser by Rassie Erasmus in South Africa in the '70s I believe. It was notable for the distinctive Blenheim sights, and the fact that the maker had the good sense to leave the perfectly-struck Portuguese crest and date intact, along with the marvelous row of large waffen-ampts down the left-hand side.
So often the history of the original action is ground away; certainly the case on most all vintage British sporters.
Also my .416 Taylor was built by Vic Pedersen in the late '80s on a totally cleaned-up Brno VZ-24 action, radius-ground receiver ring and left side of action filed clean of all maker's marks. It looks pretty darn good too!

Your project, your choice!

...although I personally can't equate any evils perpetrated by a bygone government with the historical hardware they left behind. We can't change history, nor can we deny it.

I agree on an intellectual level and would not be one to remove, enhance, or alter any original markings on an historic artifact.

I have, however, passed on a half decent Luger at a half decent price because of the Nazi Eagle proofs. To some they add value, but not to me.

Good points Marrakai, and I a still a bit on the fence. I don’t think I’ll worry about filling the pits - I can always use the cleaner receiver where the pits are minimal, below the wood line and wood stone off relatively easily...

yes that’s it exactly - that’s how I feel. It’s more a subconscious thing that I can’t rationalise. I think I might try scrubbing the more pitted one up, see how it goes then if I don’t like it/it’s not working out I’ll use the better one...

I’m the meantime, I received this yesterday. I now have a piece of genuine Type B to add to the build. Thank you very much spud303!

I missed your question on trigger guard bow dimensions. I don’t have anymore Oberndorf rifles proper, mostly rifles out of Thüringia so most are modified somehow from the original Oberndorf profile. I can dimension the one in this thread which is probably the closest: http://forums.nitroexpress.com/showflat.php?Cat=0&Number=340523&page=0&fpart=1&vc=1
It has been narrowed at the top of the bow however so maybe only some dimensions would be truly helpful.

Ok on to front sights. So the original type B sight was generally a long (or pre war, very long) ramp with knurling (?). They had a horizontal dovetail for the bead. Recknagel offer a few ramps, all there dovetail ones have smooth curved backs. I want dovetailed partly for originality but also because I need windage adjustment (rear has none). Are there any other options for ramps?

The other route is a banded front sight. Jon speed says type As had a unique banded sight, but also includes a drawing of an identical looking (to me) one that he suggests was general. Can anyone expand on this? I’ve never seen a photo of a type B with a banded front. Prechtl makes a nice type A repro, and I like the idea of a banded due to the strength (although the force required to unseat a soldered ramp would be alarming...). But it’s also AU$200 shipped - I’ve hit a wall with funding for this at the moment so would have to wait on that for a while. All Recknagel banded ramps are slotted not dovetailed.

Last option is to Make one from flat bar. Cutting the dovetail would be easy enough (have done barrels) but barrel profile concave would be harder - maybe a rats tail or welding on a section of tube with the correct ID. Could even weld on part of a file on the back for knurling.

Wedgie:
A significant part of the appeal of a commercial Oberndorf Mauser is the barrel taper, as noted in your initial posts. Without it, you lose the fabulous lines that define these classic rifles.

A 7mm or 8mm barrel will likely taper from 19 or 20 mm where the taper starts in front of the chamber, down to 14-and-a-bit mm at the muzzle. Front sight ramps consequently need a little bit of fiddling to fit properly.

And IMHO you won't want a mill-bastard front sight ramp! Pretty simple to just file-cut the ramp for ribbing or checkering.

Yes I’m sure you’re right - I’ve just been experimenting and my new Sykes pickavant thread file will cut down to 34lpi which Looks plenty fine enough, I think it will come up well. So my only hurdle is cutting the concave for the barrel.

And yes the barrel tapers from 19.2 to 14.99mm at the muzzle (as per spud303s)

I’m leaning more towards the scrubbed receiver. I’ll keep the other less pitted one for a future project I think. Had some luck taking the crest, some of the pits and the RH nazi proofs off with the stone. I’ll probably clean a few more pots off later.







To leave the serial though I had to fill the LH proof. Removed bluing with vinegar first. I cleaned the locking lugs and shoved a tightly packed wet rag in. I gently heated the proof area so the weld wouldn’t cool to fast and quench the MIG wire and make it too hard to work. Then a quick blip with the MIG and it was gone. Locking lugs barely got warm, let alone annealed.





I was concerned the MIG spot and ghost of the crest would still be visible after finishing so did a trial with the rust blue. Looking promising (to my standards at least!) even if I wasn’t overly thorough converting the rust with steaming. This is after two passes with a bakers soldering fluid/copper sulphate and trace hydrochloride acid mix I made up a year ago but never tried. I’m still thinking of giving ammonium chloride a go too, but this is quite nice even stopping at the coarse whet stone.

Needing some feedback - how’s this for an authentic bolt knob? I think it’s close but can’t work where it’s off now. Dimensions are effectively the same but it’s a bit longer (I like a long knob) - 64mm as opposed to 60 as per Prechtl’s medium offering

Stock’s in da house! (Literally). Lovely bit of xxx walnut and perfectly shaped - thanks to Hatcher’s Rifle Stocks. Man do I have some work to do...







A question though - when Inletting do you do bottom metal or receiver first? If bottom metal first, do you use any form of dowels to help locate it?

Bottom metal first, order or make a set of guide pins for a Mauser, that will help drop the action in squarely as you go. I learned the hard way on a solid block of walnut on my first stock, by doing the action first, what a nightmare! That’s a mistake you only make once haha.

Thanks mauserkid, I was going to make some inletting screws them read a tip about 1/4 UNC bolts so got a pair of 2” ones today. They screw in a few turns and sit nice and straight so will try them.

When inletting the bottom metal - I assume you have to do it by eye (no screws or guides)? Pre inletting should be true so don’t think this’ll be a drama

hi wedgie, about the length of bolt, the straight down tear drop style bolts traditionally come down so the bottom is level with the bottom of the wood work, I’m wanting to use this style on a project and my gunsmith told me to get my bottom metal etc sorted before I get him to do the bolt, he also confirmed the bolt should reach the bottom of stock/metal, if you have a drop box of course the mag will be a bit lower again, really enjoying this thread, keep up the good work!

I'm surprised there is so much wood to remove, the guy that panograph's my stocks gets them so close all I need to do is scrape the inletting to get a perfectly snug fit. He's 10-15 thousands under size, guess I'm spoiled.

Thanks - that’s a good pointer and one that’s very hard to pick out in photos. I was thinking 59mm (that’s prechtl’s standard length) so will check that ends at the wood

theres not that much to remove - bottom metal is pretty much dead on, a tiny bit needs taking off the rear “tang” at its extreme length. Receiver a little more but as they vary quite a lot I’m glad he didn’t make it too close. We discussed various aspects especially the barrel profile and decided it was much better to have wood to remove rather than gaps.

Wedgetail,
Yeah the TG should nestle in nicely since its pre inletted. Still, as you smoke the metal in, if you’re not aware of the geometry with frequent checks, you can start to get it off kilter. This is a case where it’s possibly easier to drop the metal into a solid block than a pre inletted stock since you have a better reference for square and true. This is another reason it’s good to leave plenty of meat in the channel, if you happen to get the TG off slightly, it leaves you with plenty of wood to prevent any gaps as you drop the barreled receiver in.

Thanks Mauserkid. The shape of the TG inlet was pretty much perfect, the depth didn’t go as smoothly as I was hoping... I must say I do enjoy inletting - very therapeutic. Had to sink the bottom metal In quite a way to get it flush with the lowest point of the timber. This has meant I’m going to have to trim down the mag wall by about 1mm... otherwise it’s the fits pretty good! Excuse the grubby surface - inletting with lamp black is quite messy.

Much excitement today - barrel has finally arrived! Dimensions are all pretty good, a couple of areas need tidying up a little but it’s exactly what I was after. The hand lapped bore looks beautiful. They’re also lending me go/no go gauges so hopefully I’ll start on the threads and head spacing it shortly.







Got a Colombian carbine rear sight sleeve on the way too - it should be a good substitute for an original Type B sleeve, especially after some contouring...

I like your thinking! Yes it’s a very good point - and not entirely unrealistic too. My main reason for wanting to build a copy is that I love the look of them, I’m never going to be trying to pass it off as an original so might as well put what I like on it anyway. Although I making it a Type B original As I can gives me bit of a tickle too...






Quote:

To be honest I am having problems deciding on quite a few details that could go either way. It took me a while to work exactly what I liked about classic sporters. I thought I had it fully nailed on a 100% Type B, then Cameron Hatcher made me aware of Plezier Mausers and that threw me a bit and gave me the side panel bug... I’ll try and do a bit of a progress report early next week I think




So what stock profile have you decided on?

I rather like the slab sided Haenel Mauser with Prince of Wales grip that MauserKid posted earlier: https://auctions.morphyauctions.com/LotDetail.aspx?inventoryid=445617



Here are the types and styles offered in the '39 Stoeger:

Stutzen:


Kurz:


Type A:






Type B:




The 1939 Stoeger does not list the 28" barrelled 'Afrika' model.

I decided to go smooth sides - no slabs. I was still in two minds and not 100% sure I made the right decision but it’s done. I guess my reasoning was the actual type Bs very rarely had them, and I love their clean lines. So the stock is a Type A with enough wood left on the fore tip to form a schnabel

Taking it steady but got the threads cut and set the headspace at Go Gauge + 0.004”. Got some tidying up to do now...

Thinking about the barrel channel in the stock now. I assumed I’d free float it but starting to give pressure bedding some thought. Am I mad?

thanks for the kind words NC. I wish I could give a nice big juicy update but, well I can’t! I can’t screw the barrel in yet as waiting for paperwork to come through (it can’t be a rifle until that is sorted).

I’ve almost finished cleaning the barrel up, and have started reprofiling the Colombian carbine rear sight base. I just need to close the bore a little - the barrel came in slightly under spec. I cut it length ways and closed it up then welded it with MIG. Big mistake - it bubbled and spat horribly leaving heaps of massive voids. Anyone know what steel these bases are made from? Doesn’t feel like cast... I’ll try oxy welding either with mild filler or GP (like 12p) arc rods with the coating knocked off next but wondering if anyone else has run into this?





Also done a partial stoning of the action and am really pleased how it’s turning out. The pitting is now shallow, minimal and all below the stock line

Belated thanks 93x64!

Long time no post though. I’d like to blame the registry for only just sending the registration papers for the action so I can get a PTA to add the barrel. But in reality I’ve been flat out with life and other projects. Such as these, which have absorbed every scrap of free time…


Yes the walnut slabs are an off cut from the offending stock

But I have made a little progress. I’ve made the front sight ramp to original dimensions, and am working on the rear sight sleeve still (it’s dimensioned and profiled but full of voids around the shroud so I’m working on a thin sleeve to cover them all up. I’ve also scored a mint all steel Lyman 57SME.







Hopefully I’ll make slightly better progress now…

Kind of embarrassed to update this as it’s been so long. Not entirely my fault - decided there were too many issues with the barrel even though it’d been 18m since I received it and I messed with it quite a bit they agreed to make me a new one which was pretty decent. Although it missed out on a few specs I’m much happier with it and pleased with how it’s going.

Also the stock has been cut down too shallow - once inletted till the bottom metal was flush in all areas, and the receiver likewise they were too close together - bottoming out on the mag wall. I had to relieve so much off the mag wall the bolt wouldn’t close on 5 rounds. I removed metal from the follower and now it just closes… the shape is good and it looks at home, the shadows are making the gaps look bigger!

Anyway, like I said it’s now in a good place. It's feeding RNs at any length now and even empties (apart from the last one)! Headspace is still go+0.004". Next up - bedding with Devcon, making and fitting barrel band and fitting front sight. Need to source another extractor as this one isn't gripping rims as tight as I'd like. Really looking forward to shaping the stock.

Thanks Nitro, well still inching forward…

The got the front sight on. Superglued it first to check zero (with the Lyman 57 mounted and set to centre), then scribed it. Was slightly apprehensive about taking the oxy to my nicely finished parts (only other torch is a dirty old Kero pressure job). So practiced on a dummy sight and ancient 303 barrel that lives in my truck toolbox as a binder ratchet handle until was satisfied I had it sorted.

Then clamped with an old earth clamp, masked the area with 2b pencil, tinned the sight with hi-force 44, drilled a few wells to hold more solder, fluxed the barrel and sweated it on. Reckon I got a pretty good joint. Clean up was a bit slower but it’s fairly clear now after making a brass angle chisel from a gate valve shaft. Working on the rear sight now


Caliber mark came out well too

Thanks 93.

Spent a bit of time on the bottom metal:
Hogged the lanyard (or whatever it is) hole out.


Cut the hinge out


Formed it out of key stock


MIG’d it


Inlet the DST




Filled lock holes




Cleaned up ok




Just waiting for another sear to replace the bubba’d one so I can start on the Dunlop style double lobed kicker

Thanks guys. Kind of like a long distance endurance race I guess…

Anyway the metal work may be finished, final cleaning up and tang filing excepted. Spent a while on the trigger and pretty happy with it - crisp 5.5lb pull on the unset front and a decent hair when set. To achieve this:
Built up the shroud to take the slop out to allow for a consistent cocking piece to sear height


Cut down a trigger, added a bit of (roughly) 1045




Welded a nut to adjust the depth of sear engagement, and formed the two lobes for the two triggers.


Unfortunately, once fitted up and tested front pull was 12lbs, and that was after I cut down the sear spring as much as I dared. So I swapped out the solid bit of the kick off piece for a 1/4” ball bearing. After polishing the lobes, polishing the receiver where the contact point is, hardening and replacing the pins with drill bit shaft, this reduced it to 5.5lbs





Pretty happy with its function now. Thoroughly tested operation with the bump test, repeated opening and closing of the bolt, trigger pull with safety on then releasing safety, all good. Think I can now move onto the stock
