Spring specs are as follows: Diam. of wire .0120 +/- .0005 Diam. of coil .060 +/- .002 Free length .133 Spring rate 54 Lb/In ref Solid length .086 Max I'm not looking to hit the above numbers exactly, but if I can that would be great. Steel/Stainless steel, either is fine. I've found some .059/.060 OD springs near the free length and solid length specs I need, but the minimum order is huge and I only need two springs. I've checked Brownells as well and they do not appear to have small enough OD spring stock for this project. Anyone have any bright ideas? Thanks. | ||

Order the KIT #3 - SKU 10030 MINIATURE COIL SPRINGS from Wolff. I was looking for some tiny springs and this fit my needs. https://www.gunsprings.com/GUN...s/cID4/mID132/dID373 | |||

They don’t list sizes but try Dixie gun works give them a call they have always been nice when I stop and visit. It’s been a couple of years I guess i need to go by there https://www.dixiegunworks.com/...llText=Coil++spring+ _____________________ "We're going to die. Some people are scared of dying.

Nothing "close enough". | |||

Have not, and at $13/per I think it is unlikely they would (I also would not ask as there would be no follow up order): https://www.asraymond.com/catalog/C00590100125S | |||

I may call them Monday to ask for some kind of kit list for that. Interesting. | |||

https://www.newcombspring.com/products/micro-springs https://www.drtempleman.com/co...gs/miniature-springs Both of these places work in wire diameters down to .002-.004. Don't know if they will sell you just one though. | |||

Have you tried MSC ? Bob I am no expert, but think I am sometimes. | |||

They were the first place I looked as I have one next door to where I work. They list the Raymond springs I posted a link to, but they are a fortune and the minimum order quantity was large. | |||

Xer0 and 41, it looks like Templeman has a couple that are close, and they are a buck a piece. I'll call them tomorrow. ScreamingCockatoo, not a bad idea. I have not worn a wristwatch in 25+ years, but I think I saw a couple of those spring pins in one of my parts drawers in the recent past. Now can I find them again..... | |||

Did you note the "close wound spring, coils in contact" in the description. That is NOT a Compression spring, it is in fact an Extension Spring. The good news is that you provided a link to an excellent resource and after some poking I found one that is quite close to what the OP is seeking. http://stocksprings.drtemplema...00/can-0137-0952-s-1 M1Garrandy, if you need an EXACT spring as you requested you wont find it and I don't think that you'll find anyone willing to hand wind it. Because the tolerances you have requested cannot be held. Seriously, +/- 0.002 inch for coil diameter on a spring, you would be doing well at +/- 0.01 inch. I would suggest that you consider the concept that close enough is good enough. In which the link I posted may be close enough. I've stopped counting. | |||

Colt SAA uses a coil spring in the firing pin about the size your looking for. I looked but I can't find one to measure. The spring I'm referring to is #38 on Numrich diagram for Colt SAA, they are about .060 od but I'm not sure of wire size. Or you could wind your own from .012 guitar string . If you know anyone with a lathe they could wind up a nice one . Your local gunsmith may have one too. Out of curiosity what is the spring for? | |||
