A gas fired forge in the making
      #297051 - 14/03/17 03:37 PM

I got another batch of knives heat treated today and it reinforced the notion that I needed a better way to do it than in the kitchen fire. I had been looking at gas forges for a couple of weeks and decided to build one for myself. There are a couple of good videos of how to make them from the 20lb gas bottles so when I was in the city yesterday I went to the metal scrap yard but the only gas bottle on the yard, had the top cut off it but there was a stack of lazer cut 10 3/4 in dia x 3/16 discs there so I got two of them as well as a length of 1 inch black pipe for legs.

This is the bits I bought home.



So the first job was to grind the opening out a little to fit the plate which was a simple mark and grind.



I decided to do the bottom as well because when they were doing them on the youtube it seemed like a bit of a chore to make the insulation conform to the semi rounded shape so I figured that a flat surface woudl be easier.

Then it needed a little clean up to make sure the plate fitted nice and flat. A friend just down the road welded the plates in place for me, so that all needed a clean up. I gave it all a good going over with a heavy flapper disc on the grinder to get rid of the old paint and the bit of surface rust.



I set it up with a couple of blocks to hold it still and make sure it was more or less secure for the marking out of the next step. Having the flat plate on the ends made this easier so I was pleased that I hadn't started with a complete bottle for a start as I might have had to do it on the curve surface.
Finding the center of the plate both verticall and horozontally was a simple matter, so after leveling the line accross the front (and rear as well) I was able to do the vertical which allowed me to mark the top center mark where the handle will go.



I have seen various measurements for the offset of the gas inlet from 10degrees to 30 and as the idea is to make the gas swirl round the inside of the forge I went with 25 degrees. Marking a square on the board and a 25 degree line in, I could go up the line by haf the dia of the bottle and get the measurement away from the center line that would give me a 25 degree offset.



So that can be marked on the top of the bottle ready to be drilled for the gas inlet.



That is where it will have to sit till the gas bits and the insulation get here in a few days. I will need to get the exact height of the insulation plus the fire brik floor before I cut the opening at each end.

I had a busy day in the shed with the forge up to as far as I can take it untill the insulation gets here and then I got the bolsters on two of the knives I am doing and the handes on the third.
This is a video of the stage the forge is up to now.

Made some progress on the forge yesterday and the first thing I needed to do was to get a hole through for the gas supply. I read some more on the angel of delivery and ended up going with the full 30 degree offset. So lots of 1/8 in holes round the perimeter



Some time with a good 1/2 round file, the insulation in and away down to the garrage to get the the end welded on and the outer gas delivery pipe welded in


The venturi system has a nice air supply regulator with it fully open here for full heat forging. I saw a video with this gas system and he reached welding heat in 2 1/2 minutes


And closed right down. For the heat treating the air supply is closed down quite a bit to controll the temperature

The fire brick was placed in and settled down into the insulation



The rigidiser was sprayed onto all the insulation, the refractory cement was mixed and laid into place



Now I have to wait a few days for it all to dry before it gets a firing


In the meantime I had a look at the piece of a press die I got from the scrap yard the other day. It is a ft and a bit long x 4 3/4 x 2 with the bottom very neatly radiused


I decided it is a bit long for what it may turn into so I have marked it out to be cut back to 8 inches and will look for a piece of 4x4x8 steel and a piece of 2 or 3 in round stock when I am down to the city again next week. It is all going to be reconfigured into an anvil for a bit of steel pounding which almost certainly means that some work will be done on it with hot steel and a hammer.

I got the three knives I have on the bench all handled over the last couple of days and today saw them all shaped up and sanded through 220grit.

brass and micarta



ebony and zebrawood



This one though is a synthetic material of some sort (from a bench top) so is ready for a coat of sealer but am yet to find out if he wants a sheath for it.

I have a thread on another forum where I have been posting a number of the projects I play with but didn't think most of them would be of interest here but thought the gas forge might be so have just continued to post here what I have been posting on the other forum. That is why it might seem to be a little disjointed

A little more on the preperation for the forge and its accesories after a run into the city yesterday

I remembered a piece of 3/4 in wearalloy I had as a target plate and looked at it as an anvil top instead of the heavy die plate but will make a final decission later on although I cut and preped the wearalloy just in case I decide to use it.



I got a block of steel for the main body that is 8 x 8 x 4 and a plate for the bottom that is 12 x 6 x 1 and they weigh in at 33 kg so if I go for the die plate at 17 kg that will be a 50 kg anvil.



I made an 8 x 6 stump under the end of a heavy stool to sit the anvil on so it should have a steady solid base.


When I was doing a bit of work on the brother in law's carport and widows yesterday, I asked him if he had any old fire extinguishers as he used to work for a fire protection company before he retired and he bought out this beauty and gave it to me. It is stainless steel and will hold 3 1/2 gallons (13 liters). I am not sure if I need it full depth but I hate to cut it down.


Two new 20lb gas bottles, a regulator and hoses for the forge have all the bits necessary to finish it now and just have to get the rest support tubes welded on and it can have a painted and be fired up. I will have to make a barbeque type trolly to sit the forge and gas bottles on but have enough inch angle in the shed to do that, and will get to it over the next week or two.

And just to confuse everyone

These knives are all finished now so I just have to hot wax the sheaths, give everything a final going over and they will be ready for delivery.






There was another two that needed the finish to the handles so they were attended to as well.

My word VG you are a half handy sort of fella. Big effort for sure and nice knives. Thanks for taking the time to post it. The office I rent is part of a saddlery workshop the owner has been playing with making damascus steel in his forge left over from his shoeing days. He has come up with some nice looking bits of steel.

My father had a the three punch marks to mark his tools and when I investigated getting a punch made by the die makers in the US it was going to be over US$150 so I decided that my fathers tool mark would be my mark as well. Simple, cheap and distinctive so it serves me as well as it served my father.

A very interesting and informative thread VonGruff.
Really like your knives mate, they look like they would work well.
Interesting build on the forge too. Looking forward to seeing it fired up.
Great photos and write up.

VG would it be possible for you to add some more info on your steel choice & forging/tempering techniques? A run down on the knife making process here would be a good bit of additional info to add to this thread!
Keep up the good work mate

Not all the knives are my own patterns as some request changes to suit their own needs. I will take a pic of my patterns tomorrow and it will show a commonality of style but others have differing needs or ideas.

The fire extinguisher quench tank had its top cut off and a lid made but there is still a couple of handles to be done for the sides for when it needs to be shifted. With a 3 1/2 gallon capacity it should do nicely.





The steady rest was welded up and so the forge could get a coat of high temp paint.

Needing something to set the forge and gas bottles on, a few bits of angle iron were cut into apropriate lengths with a top and a shelf cut ready for when it is welded up.



Then it was back to the anvil. The base had the mounting holes drilled and the heavy block cleaned up. I decided to go with the die plate and cut a piece off the end that will be welded on the heavy block with a step down. I still have to do the hardy holes and get a horn made.

I mentioned that I would show a couple of my patterns but first here is a few of the knives (well used) that I have made for myself over the years
A steaking knife from a farries rasp with walnut, a slasher blade slaughterman knife with micarta, a file boning knife with jarah, and my farriers rasp skinner with giraffe bone (with hidden pins) and buffalo horn.



A few hunters. A trial one to see if I could manage the double bolster with brass and walnut on a slasher blade, knickel silver and african blackwood on my great grandfathers slasher, west coast (US)walnut and stainless steel on 52100 steel, knickel silver and ivory micart on sweedish sandvic steel and my little rabbit knife with jarah on a commercial hacksaw blade. On the right is a mini cleaver with jarah on a blacksmiths rasp

These are my hunter patterns now

A pig sticker, wapiti hunter, and two sets of skinner hunters and a general hunter with two handle styles



A light hunter, bird and trout with a field scalple/rabbit knife that is also a fruit knife pattern



And as shown in finished knives, my steaking knife, slaughterman, skinner and boner.

This is a thread I have going on another forum where I have been documenting the making of the knives. It started out on just the one african themed knife, the skinner shown above with the giraffe bone and buffalo horn but because of the interest shown and feedback posted, has carried on with the making of my new 72 inch belt grinder, a few other projects and a few more knives.

Untill recently I had been using slasher bladers and pruning hook, files and farrier rasps but am now using 1/8 in / 3.2mm 1084 for the general hunting knives, .2 in / 5mm O1 for the pig stickers and .09in / 2.4mm 15N20 for the kitchen nives. It is all carbon steel but I can heat treat this steel here at home by taking it to non magnetic heat and quenching in 130 degree canola oil then tempering at 185 degree (C) for 2 hours.

There was progress today with the forge bench done and everything set up so as soon as the new regilator gets here it will be all go.
I took all my anvil parts down to the garrage and had it all welded together. After a bit of time cleaning up all the welds and splaters it was bolted to the stool top which will be bolted to the concrete floor but in all reality it is really quite stable.

I was talking to the supply outfit about the regulator (and to order another 8 ft of blade stock) and it should be here in the morning so the forge can get its first heat up. I had a batch of knives ground up so gave then a hand sand to 360 to be ready for the heat treat which I cant do for a couple of days as I have been helping a friend to shift house (to a town an hour away) so it wont be untill I get that sorted out that I can get back to the shed.




A boner, general hunter, 3 hunter skinners and a wapiti hunter. One of the hunter skinners and the boner are for me. I have a field scalpel and a light hunter (for myself) away being heat treated as it is in a SS (N690) which I cant do with my equipment.

VG have you considered grinding a few bars of ready rolled Damascus bar stock?

As you undoubtedly already are aware its out there with reasonable pricing too.

Untill I have a means of regulating or holding a set temp in the forge I will probably stick to the carbon steels for now.
I have a few projects to do as far as forging goes with a need to make a few sets of tongs, punches and drifts and may even look at making propper hammers instead of just trying with the face corrected ball peen hammers that I have for now till I get going propperly.
I would like to get into forging a bit of 1084/15N20 damascus at some stage and of course want to try cable damascus, but will have to learn how to read the forge and get the best from it before I start branching out from using plain carbon steel and eat treating it.

Its a start as there is no forging in buying damascus bar stock, just shaping and you seem to have that pretty good.

I guess I am of the character type that prefers to do these things myself. Part of the learning process will be figuring out how to do it with the other side of the equation being the cost of shipping to get the damascus from the US to here. It is expensive enough to get in belts etc without adding the weight of steel to the package.

Things came together this morning when the regulator arrived and I could get back to the shed. It didn't take long to get things assembled and the forge fired up. I had an old pick that I will never use again so I cut one of the pick arms off so it would fit in the forge to see how long it would take to get to red heat. I turned the vodeo off just before it reached the heat as it is a bit boring but from cold it took about 7 minutes to get to heat so I plunged it into the oil quench tank to bring the oil to temp for quenching the blades I was about to heat treat.
6 minutes of watching it heat up but for me it was interesting so this is the video

I had ground another two boning knifes yesterday as I had another order for one and thought to get one ahead for a stock blade that I would just have to put a handle on when needed.
I was very surprised to find just how quick it was to heat treat the blades in the forge with 8 being done in about as many minutes.

I have these knives uo to the stage where the handles are having the finish applied so today I started on the sheaths.
I got in a new double shoulder of 3mm (1/8) cowhide so marked out the patterns with as little waste as possible.


I had a little lefy from the previous piece so made up a couple to make sure my new patterns were fitting the knives propperly and then cut out the rest.


With the belt loops sewn in and the welt glued in I will leave them till the adjustable U groover gets here to make the turn over of the back to the front much easier. A friend showed me his and how he runs a couple of grooves down the inside of the sheath either side of the center line and the leather folds over and lies much flatter for punching the stitch holes.



Before I started this morning I made a third hand to make the stitching much easier and when I stitched u the couple of trial sheaths I was quite impressed with how much easier it is compared to how I had been doing it for the last near 50 years.

So this is the knives as they stand at the moment. They still have to have the final blade finish and be sharpened.
First are some hunter skinner and this first one I was going to keep for myself, but will probably sell it on as I have some lovely wood coming from the US, thanks again to Frank (on another forum)who has made much of this possible by sourcing and shipping various goodies for me.

and a few boners

First is a special order companion knife to go with a light hunter in the same walnut and jarah shipped of a short while back



One for myself in a specail piece of walnut cut from my late fathers yard in the early 80's


And a plain walnut one just to start getting one or two ahead for casual sales.



I seem to have missed getting a pic of a general hunter in walnut and jarah but it is on the bench anyway and as ready as these are.
In this pic of them in the sheaths thata still have to be hot wax dipped there is three extra that are still to be finished. On the far left is my own personal light hunter in a fantastic piece of olivewood and buffalo horn that I will show propperly when it is finished with the top left being a new killing knife (for the sheep) with walnut and copper pins, and a little field scalpel with buffaol horn scales.

Re: A gas fired forge in the making [Re: VonGruff]
      #300286 - 10/05/17 03:17 AM

I had sent an email to the Australian supplier of the gas equipment for my forge asking about the setting as I didn't seem to be getting the heat at the same rate or the intensity that he showed on his 'how to' video. He rang yesterday (from Aus) so we had a good yarn with the advice being to drill out the jet from .7mm to 1mm. Because of the slightly different gas between AU and NZ I could get the gas flow with less pressure. When I did that it was night and day different so I had a crack at forging a couple things I needed. The first thing was a slag hammer as I had been given a stick welder on permanent loan, so used part of a small jackhammer chisel, cut the top off, forged the chisel end out flatter and made a point on the other end. Some of the videos I saw had them drift a hole through the chisel and taper the handle then rivet it on the other side of the head but that was more than I decided was necessary so I simply welded the handle on. Not too shabby for a first effort I thought.


I had a bit of trouble holding the chisel when I was hammering on it as while my extended handle pliers would open up wide enough, the handles were miles apart and not able to be held in one hand so vice grips sufficed even though I had to double handle everything to get it out of the forge and then take a grip wth the vicegrips to take it to the anvil so the next thing I really needed was a set of tongs that would hold something larger than flat stock. I had picked up some 1/2 in round rods so cut a couple of pieces and went to it. Again it was difficult to hold but eventually a rudimentary set of tongs emerged so I was reasonably happy. Will try a different tack next time as the full tong from 1/2 stock makes them quite heavy so will try to do the jaws from the full size then forge the reins down through 3/8 square to 1/4 in round at the hand grip.
At least these will help to get the next set underway.

Having done that I put the head of the pliers in the forge and when they got to heat I simply closed up the handles till they would hold the knife blades with a single hand grip. Really leased with them and will continue to use them for placing knives into and retrieving them from the forge.

      #300287 - 10/05/17 03:17 AM

While I have a couple of ball peen hammers and forging work can be done with them, I see thatmost of the serious "smiths" have a special hammer that is flat on one end and radiused on the other, weighing about 2 1/2 to 3lb so I thought I had better get one as well. At the scrap yard last time I wanted a bit of round stock to make one and the guy asked if an old sledge hammer head would do as they had a few 'out the back'.
I found one that was about 4 lb so thought that would be a good base to work from.

I needed to shorten it a little to lighten it and after a while of cutting on one end it struck me that it would be hardened so I fired up the forge and when it had got to heat, put it in a bucket of sived ash for the night to anneal it. Made the cutting a little easier so rounded one end and radiused the edges on the other and after a bit of a clean up, put it back in the forge to heat treat, did the quench in water then tempered it in the cooling forge. Found a suitable piece of beech and knocked up a rudimentary handle and now have a hammer that weighs right and swings nicely.



The rounded end is for moving metal and making a thinning process a little quicker then the flat end is used to planish out the dips and hollowsthat the rounded end caused.

By then I had got another Lee Speed stock and a few other projects up to a stage that I could get these blades cut out of the flats stock today, so should get them all profiled tomorrow. On another forum the guys decided they should do a group buy so these will all be done together for them, plus a couple of extras.

Have these blades all ready for heat treating now with their individual handle scales all marked for each knife with the name of the recipient scribed onto the tang so that will do for this week. There are different handle requests with some having bolsters (jarah or ebony) but all having scales from a rimu board I had set asside for them . There are a couple of foriegners in there with one having jarah scales and the hidden tang with brass jarah and beech. There were some that wernt part of the group buy that are set asside for now but they will be attended to after these are completed.

I got a few more blades from the drawer ready for heat treating so it will be all done in one session. The ones without handle scales by them are for spec so have drilled them for either bolster and scales or simple one wood scales. The one with all the lightening holes is a piece of 1/4 in D2 that I started some time back and have tapered the tang so may finish it with something nice.
With all the clamps finished and painted I should have no problem getting all the handles sorted without having to wait for apoxy to cure before removing the clamps for another batch.

Have finally finished getting these blades handsanded after the heat treating so they are now ready for the handles but that is going to wait for a couple of days as I have something else to do in the meantime.
This is how I do all my handsanding with 220, 360, then 600grit papers round a 3/4 in square hardwood block.

I got back to the shed today and all the blades that were to have bolsters were attended to. The bolsters were all fitted then pinned and epoxied on. It was a real treat to be able to use the little clamps instead of the much longer and way more clumsy clamps I had been accustomed to using. Seeing as we are having very hard frosts in the morning I set a light with 200watt bulb to create a heat shield above them to stop any epoxy degradation from the cold.

This morning I got all the knives out of the clamps



Profiled them with the 60grit belt on the 12, 4 and 1 1/4 in wheels, run them through the bandsaw to do the primary shaping then used the 12 in wheel to get them to a rundimentary shape.



Then got a couple handsanded and finished up to 360 grit. I did have to make a new finishing block as my other one will only hold about 10 blades and it will be easier if they are all together in one place when I am doing the finish which is a few of coats of thinned spar varnish (sanded between coats) to seal the surface then the oil finish can be done over the following couple of weeks.

I have only done a few kitchen knives for myself so far from a carbon steel (15N20) so havent done anything with stainless that wiuld be more suitable for kitchen knives for sale. I would have to send stainless steel blades away to be heat treated.

Have these all with the first coat of sealer (thinned spar varnish) on them this morning so that will get sanded back to wood tomorrow and be repeated another twice before the oil finish is started so should be able to get to the sheaths and send them of in about 3 weeks. Unfortunately one of them has had to be rejected due to a flaw emerging during the last sanding stage and I can not send anything that is not up to standard.

They have to be up to a reasonable standard and if not, then that is just what happens sometimes.


There is a very exciting project in the making that may interest some on this forum so will start a thread later in the week. Look for the Safari knife project that is starting in consultation with an experienced group of hunters and hunting guides.

Have had a couple of day on the leatherwork. After the knifework, the thread groove,makers mark and stamping was done before the top part of the belt loop was glued and sewn on. The welt was then glued in and the belt loop folded over and glued in position ready for sewing tomorrow. Then they can be folded and glued in thier final position before the thread holes are drilled and the main sewing starts.

Sheaths all ready for sewing now with 7 different sizes for standard right handed carry, one for a left and a horiznotal carry. There is another horizontal carry cut out but the guy it is for wants a darker sheath to will get the die in a day or two.



There is seven that have been stitched so getting through them slowly.

There is a very exciting project in the making that may interest some on this forum so will start a thread later in the week. Look for the Safari knife project that is starting in consultation with an experienced group of hunters and hunting guides.



All waiting for the next instalment matey!

I was asked on another forum how I make the stitching holes and sew up the sheaths so did a couple of short videos

Wow. Haven't visited this thread for some time and the work has really come along. As well as all sorts of other tools as well.

Great stuff. I can see forum members getting some of these special custom knives made by a NE forum member.

Am interested to see the final products after seeing the progress from the beginning to the end. Just about there now,

BTW one of these days when I am more financial, I can see two non knife projects in your future, if you are interested. A boar spear and a "war hammer".

There will have to be a lot more learning on forging before I could even think of venturing that far off the simplified beaten track I have walked so far.

so this batch of knives is finally done and ready to be sent of the new homes far and near

This is the line-up and while there are a few the same and similarities in them all having rimu scales there are other differences that individualise them
