1/2 Scale Colt Army Revolver

[steamer]

The Drill blank would be my first choice...500,000 psi yield, nice and round and harder than woodpecker lips....

Just sayin

Hello George,

This is an amazing model. I have sent you a PM regarding a non-firing replica of this 1873 Single Action made many years ago in Japan.

Are you going to make a walnut partitioned presentation case for this revolver?

Cheers...John

Thanks John,
I don't know if I'll make a case for it right away, maybe in the future.
I solved my .047 diameter rod problem. I have a home-made collet holder for ER 11 collets. I made it as a set-tru style so I could cut valve heads concentric to the stems. Using a piece of .093 drill rod I cut about .32 at a time down to about .048 and then filed and polished it to size. I kept advancing the stock until I had the required 2 inches. Overall the finished shaft didn't vary by more than .0005. I was certainly surprised by the concentricity of the collet even when the shaft was out at the full length.
First is a picture of the shaft and then a short video clip showing the lathe spinning with the shaft extended to 2 inches.

George you totally amaze me to say the least WOW just awesome!! Very nice!

I made the trigger and the cylinder lock. I then made up a fixture plate with studs to match the though hole sizes in the parts. These three parts were mounted on the plate and filed for proper operation.
The different positions can be seen, half cock with just the trigger, full cock, with the lock bolt mounted and shown in it's position with the hammer and trigger in several positions.

Thanks for posting this build George. I have a Ruger Bearcat 22 pistol from the early 70's, which is a bit scaled down from normal size.

Gentlemen,
The pistol is finished except for fine polishing prior to blueing. I used it as a model along with a printout of how I stepped off the shapes at the seminar I gave at NAMES. I gave some thought to someone operating the mechanism but wasn't overly concerned until the seminar was over and I found that someone had apparently put the pistol on half-cock and then tried to pull the trigger. The half-cock position locks the trigger into a notch in the hammer so when the trigger was pulled in this position the .015 tab was broken off. It only took a couple of hours to make a new one when I got home so it wasn't a big deal.

George has a gentler idea of 'no big deal' then I would.
