I already made the replacement screw for the left side of the breech block on this rifle
http://thehunterslife.com/forums/sho...t=15614&page=4 because the 'thing' that was in there was wacko - a piece of aluminum 'threaded' by screwing into the hole. Here's a picture of that finished screw. (Not colored/blacked yet.)
While the screw on the other side was 'fine', I decided I might as well replace it too while the process of making the screw was fresh in my mind. The following is a sequence of photos representing the process.
Starting blank.
To head diamter - 0.236"/6mm.
Shaft diameter - 0.178"/4.5mm
Screw cutting 28 pitch threads on 0.178" shaft for a length of 0.250" by rotating head by hand.
Finished screw-cutting
After sawing off.
After cleaning up the top and getting to proper thickness of 0.125".
In place.
I was having some issues with misfires because the extractor wasn't closing completely. After replacing this screw, that problem has been eliminated.
I'll color the screws before too long.
