Good morning everyone. I purchased an old HW70 and have run into a problem. The sear is broken.It appears to be stamped steel. Not sure if this could be welded and reshaped or if a new piece could be made. I would rather pay someone to make one than try to fix this one.I have seen some threads in the past of people offering machine work, I hope this is the right place.
I’m not exactly sure which part is the sear engagement but it appears to be more worn down than broken. I may be wrong though.
I don't think anything other than steel with some case hardening will be strong enough to work.3mm is closer to 1/8" (0.118" = 3mm). A piece of 3/16" (4.76mm) steel could work but does it fit inside trigger group frame? Will 3/16" fit with trigger blade and in piston latch area?I don't have an HW70 to measure so I'm just asking :-)I have a TIG welding setup (hobby welder) and am actually getting pretty good at it. I might be able to build up that area of the original sear with a tool steel (hardenable) filler alloy.NO charge for materials/labor. Return postage maybe, but only if repair is verified successful.PM if you (Kurt or Francois) want to discuss :-)

I could build that up with oxy acetalyne in 15 minutes. Trim it up and case harden it within the hour.See how it wore off? It probably wasn't even hardened.
