ive used JB weld to repair a cracked turbo manifold on a friends car. i dont question the durability for one second. there is really not much pressure where the sear/disconnector meet either.

if the JB weld will hold up under the heat generated by a 280whp engine. it can hold up in the 10/22. :t

what do you mean "turn". do you mean turn like an allen head setscrew? if so, sanding the JB weld produces the same effect, unless you sand too much, which is your own fault because you didnt go slow enough and check the fit often.

...for most home DIY'ers it is darn near impossible to drill the sear. I tried it a couple of times and won't bother with it again unless I get some heavy duty machinery and tooling.
I tried to anneal the part first. I didn't have much luck using a propane torch.
I tried using the BIG milling machine at work but it wouldn't accept a small enough bit.
I tried using a hand drill and titanium drill bits with cutting fluid. I broke 1 drill bit. I drilled the hole off center but finally got it drilled.

exactly why i didnt drill the sear. clamping the sear and putting it in a drill press may work, but i have no drill press. i have a hand drill and a dremel. neither of which i was going to try to drill a prefectly straight 1/8" or so hole into a tiny piece of metal.

drilling it does give a more professional result, but i dont have the equipment to do it. the JB weld worked perfectly and cost me about nothing at all.

i figured that drilling it with a normal drill would be a lot harder. maybe ill try it.
