Damn, is that the real thing? Sure looks like it.
I have been reading, but so far said nothing. I wanted to see where this might go. You can bet there is a few other guys watching too.
I have a few ideas too. The first one is there is nothing wrong, except the first click you can hear is the bolt coming off the cam at the hammer, and you have gone past 1/2 cock, and just can't hear it.
So install the hammer alone, no hand, just the hammer and the screw for it.
Next install the main spring. Set the spring in place with most of the screw not yet turned in, and use the screw to pull the spring in.
Install the bolt, install the trigger. Use the same screws as they were as original if you can. If you don't know look for wear marks and note which screw is which screw there after. Use a black marker if you can't ID these screws anyother way. If some old timer ever worked on these he may have made a Key, (marks to ID which one went where) Look for them.
Next install the dual spring, and snugg the screw.
Looking with a bright light cock the hammer oh about 1,000 times untill you can see the hammer cam, and the bolt work with one another.
Listen for the click in to 1/2 cock, as you watch the trigger drop into the first notch on the hammer. You might not hear it. listem more as you cock the hammer more. Click, did you see that the bolt slipped off the hammer cam and heard that instead?
Add a little masking tape to the side of the hammer. In pencil with the hammer down, follow the line of the frame.
next set the hammer to half cock, making sure the trigger is at the half cock notch, and mark the tape again, making a similar line in a different place.
Cock the hammer more, CLICK hold the hammer there, and make sure you saw the bolt slip off the hammer cam. Do that 10 times and then mark the tape, with the hammer exactly where it is when the bolt slips off the hammer cam.
Next and last set the hammer to full cock and mark that in pencil as before.
Last post a pic like that..
If this is a real original, don't play guessing games. Do Not file, sand, and shape stuff, not yet anyway. I am none to sure euro clone parts will work and I am pretty sure no screws will either!
Don't get in a hurry, don't get frustrated.
I would like better shots of that hammer cam, to see th top. That cam should have a square shoulder even though the cam is round.
The bolt needs to ride up on that cam with out slipping off, to a certain point. That point should be after 1/2 cock.
Do those Snap On screw drivers indicate you are or were a car tech?
If I knew that, it might help, and you really should invest in the proper screw drivers made for guns for this gun.. The blades on those drivers are about as much like a gun screw driver as a allen is torx...
