Fitting the sear
« on: April 19, 2008, 02:42:05 PM »
Norinco, Wolff power pack, AIM sear.
Sear fitting: New sear, new springs. No function-y trigger!!!

Now I knew I'd be doing some fitting, so I'm not that daunted, but I figgered it's best to be thorough. My problem's with the rebound disconnector pushing the trigger bar too far downward. Methinks the sear's slightly taller? Yep, a quick comparison w/ the old sear confirms it.
Now, rather than start shinin' the sear's top surface, the hammer engagement surface, and doubtless blowing the angle all to hell, I'm figgerin' on adjusting the sear's position on the Y axis by hitting the top surface of the rail slot on the sear, allowing the sear to ride lower in the trigger action. Shouldn't affect my engagement with the trigger bar, should it?

Am I on the right track or am I on the right track? Seems like this should be done before adjusting for creep.

OK. After putting the sear in and taking it out again a coupla hundred more times and studying the diagram and getting more solid on how the disconnectors and the sear stop function I'm thinking I'm way off. Looks like the hammer/sear engagement surface is gonna have to come down since dropping the whole sear in space by widening the slots from the top would screw up the sear stop and the trigger bar engagements. sooo... it's take off on the top and try to make positive engagement a positive thing...  :lol:

At least that's the current plan.

If the engagement is correct, shorten the secondary disconnector arms on a belt sander... you don't want the rail slots any bigger than what will allow the sear to slide effortlessly fore and aft. I fit the sear like I want it with the secondary disconnector removed and then adjust the secondary disconnector...
