It's called a parallel clamp. Search that and you'll find them
Exactly. Also known as a machinist parallel clamp. Most student machinists make a pair as part of their training.
Made one in diesel school as a introduction to using tools and measuring.
On these locks I didn't need a vise. I just had to learn to remove the spring last when disassembling, and then install first when reassembling.
Appreciate the offer. I'm going to keep my eye out for vintage Starretts or similar of various small sizes. In the meantime will pick up one of the Amazon clamps. Happy 2026. Lots of snow at C. Germania?
While you previous post was correct (LTK would say just make one) in this case “LTK” doesn’t t no no you need one. I have a couple for mainsprings but never felt tje need for a sear spring vice and while your current method appears to work, I do the opposite. Sear spring come out lady snd goes in last. Comes out last seems pretty obvious but to install last, I put the screw in with the spring just hanging wherever then run the screw in so the spring is still loose enough for the location tab to still clear the plate then just swing the spring into place, press it against the sear to compress it and snap the location tab home then tighten the screw. No tools required (usually). On some that are relatively heavy or have a more accute angle from spring tip to sear, I need to just squeeze slightly with pliers to get it started then just snap into place.
I imagine, hoping to be up there next weekend.
