1/2 Scale Colt Army Revolver
« on: April 09, 2017, 03:47:25 PM »
Gentlemen,
I know it's not a model engine but I thought some of the members might like to see what I'm up to currently. I had taken a set of drawings that were published on Youtube and corrected and scaled them down to 1/2 of the full sized piece. It's all steel construction using 1144 steel. The handle is Walnut wood. I had documentation of the build but my computer unceremoniously had a malware bug and I lost the files so I can only present what I have so far. My plan was to make it to shoot .22 caliber shorts, 1/2 of the original .44 size, but I don't think I can get enough strength from the main spring to compress the rim on the cartridge. Rifled barrels can be purchased quite reasonably so I was going to buy one and cut it down and thread it to fit this frame. Time will tell.
Currently I'm getting things ready for the upcoming NAMES show so the progress will slow up a little.

George, I think that is a fantastic project. I'm kind of into those old timey guns too. I picked up a Ruger Single 6 from a model engine buddy of mine. Looking forward to seeing you at NAMES.

Another fantastic gun model, George.  It's a masterpiece and a real credit to your skills. 

I still remember following your build of the Mannlicher...

OMG George, that's beautiful. With exception of the case colored finish, looks just like the one in top of my tool box. You might be surprised on the spring pressure. I knew a fellow ( not mentioning names) that made a couple of "pen pistols" one time and best I, er he, can remember, used ballpoint pen springs. With a sharp pin, doesn't take much.

That's beautiful George.  Just out of curiosity, what are you using as a main spring?

As has been said, that is just amazing George!

Guess it won't be very dangerous though, since nobody could fit their finger in there to pull the trigger!   :Lol:

Thanks everyone for commenting. Vince, I have an assortment of flat spring steel strips in varying widths and thicknesses given to me years ago. I use the appropriate thickness and grind the width as needed. For this application I used my hand grinder and an abrasive wheel to get the needed width. I could buy some spring steel and machine it but this is so small I don't know how I'd hold it.

Beautiful revolver George!   A friend of mine regularly goes to Russia, and he knows a guy who makes miniatures like that.    Showed me a picture of a Tommy gun, with a drum magazine, and a violin case to match!   About 1/3 scale.

Hi Dave,
I know a fellow in the Miniature Arms Society. I have a few of the magazines and some of the work in there is phenomenal. I have talked to a few of the fellows that display at the model engineering shows and most of their tooling is made specifically for building miniature model arms. In a lot of cases pantographs are used to reduce the parts. I'm not that dedicated to building small weapons to go that far. I need tools to do the broad range of miniatures that I build.
I just finished the ejector tube and slide. The tube is mounted to the barrel with a 1-72 screw.  The depth of the tapped hole is .055, just enough to get a few threads in there so it doesn't break into the bore. Now I have to find some .047 diameter rod or straight wire to make the ejection rod. If all else fails I could turn it an 1/8th of an inch at a time. (2.00 long)

George-

A .047 gage pin should fit the bill.  I believe they are two inches long.

A 3/64 drill blank is another possibility.

I'm not a welder so I don't know if they make rods this small.  That could be another possibilty.
