Prairie Dawg, SASS #50329 Posted January 19, 2020 Share Posted January 19, 2020 Good evening folks: I was stupid & unorganized when I got started years ago. I have bags of unmarked Ruger mainsprings sitting in a box & I have no idea of their poundage. Is there a way to tell? Geez, I hope I don't have to install & try out each one. My buddy Catlow once said something about it, but sadly, he is gone now. I would appreciate any knowledge you smart guys can pass my way! Thanks in advance. --Dawg Link to comment Share on other sites More sharing options...
Still hand Bill Posted January 19, 2020 Share Posted January 19, 2020 There are formulas for calculating spring rate, here is one https://www.thespringstore.com/spring-calculator.html. Link to comment Share on other sites More sharing options...
G W Wade Posted January 19, 2020 Share Posted January 19, 2020 Years ago when working with 1911 recoil springs I built a copy of spring tester produced by some one? It was simply a rod with a washer on one end and a hole on the other. Then a plate with a hole the rod would slip thru. Anchor the plate in your vice, Slip the spring over the rod, insert thru the hole in hole. use a spring scale ( like fisherman use) in the hole on the other end. Compress spring to desired length . Maybe a minature model could be set up for your problem. Just compare your misc. springs against a spring of known poundage. GW Link to comment Share on other sites More sharing options...

G W Wade Posted January 19, 2020 Share Posted January 19, 2020 Thanks SD. 2nd video is a very nice version of the one I made. I just used a piece of flat iron with a hole drilled thru instead of the pipe. GW Link to comment Share on other sites More sharing options...

That's only for the OMV. Not for the NMV. The springs at one time were different lengths between OMV & NMV. OLG Link to comment Share on other sites More sharing options...
J-BAR #18287 Posted January 19, 2020 Share Posted January 19, 2020 Life is short. Give the bag to Lassiter the next time you see him, and start fresh! Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted January 19, 2020 Share Posted January 19, 2020 Hint- There are lot to lot variations on spring making runs. When I want 2 or more identical guns to be sprung exactly the same. I call Wolff Gunsprings, and ask that my order be filled from the same lot run.

Colorado Coffinmaker Posted January 19, 2020 Share Posted January 19, 2020 PLUS ONE too J-BAR Trying to fiddle those springs is like pushing rope or herding cats. GIVE. THEM. AWAY. Link to comment Share on other sites More sharing options...
Baltimore Ed Posted January 19, 2020 Share Posted January 19, 2020 Not trying to be a smart alec but what dif does it make as long as your hammer spring sets off the hardest primer that you reload with. I’ve trimmed all my springs shorter as Ruger tends to over build their stuff to make my vaqueros more duelist friendly. I run hard cci primers and have never had issues with my primers. I recently installed the nicer wide spur blackhawk hammers in everything but haven’t messed with any of the springs. If anything they should strike my primers harder as the BH hammers look to be a little heavier and therefore have more inertia. But you could build a tool to compare your springs one to another so that they feel similar gun to gun if it’s that important. I’ve only got one professionally done action job on my main match pistols and while I can feel the difference it’s never bothered me enough to send the other gun to Bowen for him to slicken up.
