First: wow! I hope this will be as enjoyable (for us all) a watching your last thread on the 22H DR build...

I know this will not be well received, can't believe I'm writing this, but what about a "mountain" caliber (wildcat)... in the 6MM range? Could you run that in the "smaller" scale?

Mike,

The big bores will be made, but I want to prove out the .375 action size and it may accomodate the big bores. I just need to do more measuring, figuring wall thickness and such to make sure they will be serviceable.

Dugongberbulu,

I want one of these in 6mm Remington for myself....

The lockwork is in place and works great. Lots of energy on the hammer. It cocks easily. I can pull the lever with my pinky.

Right now the trigger is hard, but very crisp. It only rotates 2 degrees. I will of course tune up the trigger for about 3lbs. pull.

Here are a few shots....

This looks great. Where will the safety be? I am really interested in one of these actions for a .30-40 Krag.

Safety will be on the tang. I will have pictures of it installed by Monday eve.

I have the tang safety installed. It works great, and is very simple. As the trigger has the sear integral to it, blocking the rear of the trigger from rising stop any sear movement as well. When the safety is enguaged, there is zero trigger movement.





I know tases vary regarding safety buttons. I am not married to the one I have on the prototype, but do like it. They can be left as a rectangular block for later finishing.

This is really progressing nicely. Would it be possible to install a lever safety on the side, similar to the Gibbs Farquarson?

I thought about the side lever safety, but the major drawback is it clutters the sides of the action IMHO, and actualy the last of the Gibbs had tang safeties.
It would be possible, but I am not a big fan of them myself.

I did get the barrel tunred down to fit into the action, and just need to finish the chamber and extractor cut before installing it. Not sure if I want to scope this one or go with open sights. Scopes kill the classic look of these retro style rifles. My eyes are thankfully still good, and I do enjoy shooting with open sights. Maybe extend the tang and mount a folding peep sight.......hmmmm

Got a little shaping done. I had to get after the top tang with the welder to add material to make the tang trough lower. Already changed the CAD drawing and machined another action with the update. That's the way it goes with prototyping...

Anyway, let me know what you think.

Hi Bailey,

This project is wonderful, I have always liked the "Old" ways both by by nature and equipment. I do believe that this will be a "Winner" and will become the next generations collectable.

Cheers from Australia,

Jeff Gray

I'm really interested in the Cnc equipment your using. Who makes, what's the cost if a slob like me were to try and buy one. Do you do bits and pieces for other people? ie if I need some
work done on an action could you do it? You can pm me if you prefer.

Great stuff though. Love it and would say bigger is always better 577 and 600.

Blain,

The machines I have are a Tormach mill, ($8k), a '91 model Fanuc W0 wire edm (you can pick one up for about $10k now...it's getting long in the tooth) and I recently added an Elox sinker edm ( $2k). If you could only have one, the most versatile is the mill.

Big learning curve if you don't have any machining experience. My advise would be to find a community college and take a course.

Not really interested in taking outside work. Setting up for production is like a muti act play, everything has to work in the timeframe alloted, and small interuptions set up a train wreck to the timeline.

Let me know if I can help on machining questions.

Good News Good news.

I made another action...prototype number 2, or Mk1 Mod1 for you military types. Fitted the Gibbs style extractor, made a slight change to the underlever shape, added a latch like all godd Farkys have and a couple of other little changes for the better.

The best news is how well the extractor works. Drop the lever hard enough and it sends the case out as far and fast as any ejector I've ever used.

All that besing said, I am ready to start moving these out. PM, email or call me for details. (903)746-0004, baileybradshaw@netscape.com


I will update with pictures tomorrow.

OK, here are a few photos. As I said before, I made a slight change to the underlever shape and added the latch. The extractor and cam require the two screws on the side of the action. I must say I am thrilled with it. Makes me feel nostaligic....only cure for that is one of these in .303 for my own use.

Wonderful! Have often wondered why no one was doing this - other than Ruger's No1 absorbing a lot of the market of course. I've got mixed feelings seeing all these refinished and restocked/barreled Farquharsons etc. Perhaps if an affordable modern substitute becomes available we won't see so many of them being stripped of their history.

Trigger group is assembled. Needs a heavier main spring, but that is just a phone call away.

I've shaped the underlever a little more as well.

Here are a couple of pictures of the action next to my Ruger 1. The bottom picture shows the size difference. The bottom of the actions are alighned.

Hi Baileybradshaw,

Lovely, but don't let it get to close to the Ruger or it might get contaminated....

Cheers,

Jeff Gray

As for the largest cartridge it can be chambered for. I designed it for 30-06 sized cases, but since it requires a rimmed case, it will need to be a rimmed version in the medium bore family.

I did some research regarding the specific strength of the action. The dimensions critical to this are the action side walls, barrel band and corresponding barrel shank dia. The side walls are .2" thick, but can be left thicker if requested. ( the action is 1.25" thick)That's the same side wall thickness as a Ruger no.1, but my action has a couple of advantages over the no 1. First is the material. The No 1 is from a casting, and has releived areas where the sidewalls are thinner. I am using 4140 and 8620, and the cavity is wire cut on my EDM. The EDM produces a smooth, stress free cut. The breech block, also EDM cut is a precise fit, which reduces "hammering" from a not so perfect fit.

The barrel hole on the action is .875", which keeps .2" barrel wall thickness, plus the thickness of the barrel band around the chamber ( .164"). So, the dimensions of the barrel band and barrel shank require the case diameter to be .471" and smaller at the base, The rimm size should be .531" and smaller. This includes the 9.3x74r. So, to answer the question on the largest caliber, the 9.3X74R would be it.

Beautiful! And it covers the range of cartridges that most people use for hunting, most of the time.

Good hunting!
