This looks amazing! Do you mind if I ask how you achieve that nicely squared bolt raceway...broaching? What finished weight are you hoping for? Again, super cool!




The horizontal bolt raceway was made with a keyseat cutter.

Following with great interest. Never will have the wherewithal to have a double but a light 7x57R would be right up there on the most desirable list.

Dewey,

Any more progress to share ??

This is a great looking project and it appears to be happening quickly.

Keep up the great work and don't forget to keep us updated.

This is the rough machined bridle.



The inboard mounted sidelock. The outside "lockplate" is simply a cover and obviously will be pinless. I'm going to incorporate a spring-loaded trapdoor in the outer lockplates to access the inner workings. The cocking lever is also the mainspring. As the barrels open, the lever/spring rotates the tumbler to full cock where the sear will hold it. As the barrels are closed, the cam at the front will cramp the spring.

Here's the finished right-side lock. Almost finished, I still need to make a couple of bridle screws.

Dewey,

Great progress.

Great project. Fascinating.

Can you show a picture of the interceptor sear arrangement please ?

Keep us in the loop. There'll be a lot of people watching intently.

Fantastic project and beautiful work!

I read on your blog you use O1 a lot for springs...is there a particular reason for this as opposed to other steels such as 1090 or 1075? Do you mind if I ask what your heat treat and temper routine is for O1 springs? O1 is easier to find in my neck of the woods and would be useful for making the odd spring.

You mentioned earlier in this thread that you have been a Professional Gunmaker for 20 years.
It shows!!
Beautiful work, very impressive, superb!!
I really do like those sidelocks with false sideplates. Very neat indeed.
Please keep us up to date with this DR build.

I do use O1 for springs, the carbon content is roughly the same as for 1095 but the addition of chromium, vanadium and nickel makes for a (theoretically) more shock-resistant part. O1 is easier to find in thick sections than is 1075 or 1095 (at least around here). O1 can be forged but it must be done at or above 1500 degrees Farenheit and annealed after forging. Heat treating (harden and temper) is similar to 1095. I usually use o1 for springs that are a single leaf design or that have large lugs/projections, like the combination mainspring/cocking lever here which has a pivot lug that engages a pocket in the hinge pin.

I decided that the bridles should be pierced, in the interest of saving weight (not really).

That is awesome work. It is one of my dream cartridges to have a double built in.

I have a 30-06 and a 45-70 side by side rifle by Baikal. I also modified a 12 gauge side by side into a slug gun. My problem has always been champagne and caviar tastes on a generic diet coke and fritos budget.

This may be a silly question (again) with the system you are suing it doesn't look like there will be much remaining wood left after in letting the head stock.I only ask this because I just split the stock on a double that I am building.Cant wait to see it completed.

Thanks. The locks do not have interceptors, I'm thinking of incorporating a grip-safety.

Dewey,

I had expected one and when I saw the projection on the back of the hammer/tumbler I thought it might have been incorporated with that.

However, when you pierced the bridle, you could see that there wasn't an interceptor.

Your work looks nice and "crisp" but you've added "artiness" with your lines......well beyond just function.

Lovely work.

After some thought, I decided that since the locks will be readily accessible (and therefore visible), that they should be more visually appealing. To that end, I redesigned the sear spring (it's now a single-leaf with a bridge supporting it), beveled the edges of the bridle and bridge and cut an ornamental pattern into the lockplates (which had to be remade).

Looks superb, very similar to a Swiss watch as a they also bevel their plates and bridges. The sear spring is very similar to detent springs fitted to watches as well. Are you going to polish the bevels ? Great engineering skill and craftsmanship. Super.

Gorgeous !!!

Don't know that I'd have opted for the treatment you gave the inside of the sidelock plate...but I can appreciate the workmanship that goes into it.

The detailing of your work is impressive.

Is it your design that the first hammer notch is to act as a safety notch........should the hammer jump it's full cock notch ???

Beautiful work. Please keep posting your progress.
