I just bought a Savage model 93 bolt action 22 WMR. The trigger pull is 5-1/2 lbs with a lot of creep. I'm thinking of tinkering with it. My plan is to stone a slight chamfer on the engagement surface of the sear (the part that holds back the spring-loaded hammer which is part of the bolt). Then I plan on cutting a coil off the trigger return spring which appears to have a tension adjustment in the form of a socket-headed stud /lock nut. If anyone has any experience/recommendations for me I would like to hear them. Thanks.
Stone only enough to knock the high spots off the engagement points. These parts are case hardened, and if you cut through this layer of hardening, you'll have ruined the part.
I use a popsicle stick with 240, 400, then 600 grit automotive finish sandpaper for doing this, but the stone may work even better.
You can find spring assortments at Home Depot or Lowes. For about 3 or 4 dollars, you get a box of all kinds of springs. You will often find a spring of the correct tension and girth in this box. You can cut this spring to the length you need. Sometimes cutting coils off of the factory springs leave them too short to function well.
Thanks Dan. I'll stop by Lowe's and get the springs. That's something I've needed but wasn't sure where to get them. I've got a system for doing precision stoning. It involves using gauge blocks and a vice to hold the part, then using drill bits as rollers under the stone to keep everything square and level. I did the trigger on my Ruger 77 and it came out very well.
Thanks for the help. I bought a spring from TruValue and cut it down to length. Then I polished the sear surfaces with a stone. Got the trigger pull down from 5-1/2 lbs to 3-3/4 lbs. There is still a noticeable amount of creap but it feels smoother instead of being so jerky. I will try it this way for a while. If the creap bothers me I will stone a deeper chamfer on the sear.
