I inherited a Rohm RG 66 .22 LR. Basically, it's a smaller framed cheaply made single action. It worked fine for years (in spite of its cheap nature), but a few months ago the cylinder stopped locking up when the hammer is cocked. I took the triggerguard off today and found that the spring that works as a return spring for the trigger and as the spring for the bolt is broken on the leaf that would work the bolt.

Does anyone know where I can find a replacement, or of a spring from another small SA revolver that could be fitted to work?

Cheap as it is, it seems ridiculous to not have a gun working over such a small issue.
 
Here's the thing - if I had to pay a gunsmith a hundred bucks to pull the gun apart and tell me what's broken and look for a replacement spring for a year, I'd just throw the gun in a drawer and forget it. If it was a .38 or a .44, I'd say "no way I'm trusting a Rohm with real cartridge. It could fail and blow my face off." But it's a .22. A .22 that was shot at least a thousand times. It's accounted for a lot of aluminum cans and a few pests and snakes. When it was working properly, the lock-up and timing were fine. It doesn't shave lead. If it was going to fail, it would have done it by now.

So if I can find a spring and replace it, I will. I have to remove two screws to get to it. Two screws, a little filing maybe, and put two screws back in and the gun should work. If I can find a part to work, it will be quicker to replace than it is to strip an AR-15 for cleaning. It's worth that much effort to me to try and make it work again, and to learn something about single action revolvers in the process.
 
We were taught to make replacement springs out of bobby pins. Try it. The only cost is an angry wife/gf who wants to know why you've been twisting up and filing down her bobby pins.
 
The black with silver bails type of paper clip can be cut with aviation shears to make serviceable small flat springs.
 
Thank you guys. The idea with the bobby pin worked. Since the leaf that works the bolt was broken off, I put a leaf made from a bobby pin back in to work the bolt, then tightened the remaining spring (trigger return spring) back down. It seems to work for now. I'm not sure how long that will last, but it might have made a non-functional gun into a worthwhile plinker that I can get a little use out of.
 
I take that back. The bobby pin just isn't up to the task. But now at least I know it can be done...

Plan B.
 
I'm thinking of using either a piece of FAL magazine spring or a piece of SKS stripper clip for my next try...
 
You really can't re-bend a tempered wire spring and expect it to last, or not break.

You really can't anneal & re-temper spring wire either.

BTDT several times over!!!

I'm thinking that a small section of SKS stripper clip may do the job. It's already a flat spring with a bit of a bump on the end where I'll need it, and it's already curved the way I'll need it curved. A little measuring and file would probably do it. But it's not a huge priority I guess.

The thread on 3D guns and special ammo got me thinking - if they can print a gun, then surely I can figure out a way to stick a new spring in one that's already made (cheaply) and make it work.
 
There is a seller on Gunbroker . com called Wide Buffalo that takes scrapped firearms and removes the pieces to sell as kits. He has several different Rohm kits on there regularly. Might be a bit spendy but you will get everything but the frame and barrel usually. I have used them for parts often and you get what is pictured in the auction. No complaints from me with what I purchased but some "kits" that are listed are really overpriced for what you get. YMMV
 
Years ago I fabricated one of these RG-66 cylinder return springs out of some spring steel, it still functions properly to this day. You can use a hack saw and a 1" binder clip from a office supply store to fashion one of these springs. The metal is plenty springy enough to do the job. Take care to not overheat the metal as you cut and change the temper of the steel. I used a scribe to trace out the shape of the spring with the one leg, then flipped over the spring and drew the other, missing one in its proper position. (both spring legs are a reflection of each other)
