Hey everyone,

Well... I have an issue. When I got my M-39 bolt the lines matched between the groove on the firing pin and the cocking piece. However, while re-assmbling it, I have come across the problem where it is flush with the top of the cocking piece, but the line is maybe 2-3 mm off center diagonally. I try to turn it more, but the entire cocking piece and firing pin turn together, I can't seem to make them align! I can make them align if I allow the firing pin to be depressed about a militmeter I.e. one turn counter clockwise... help?
 
Tried tinkering with it. Great. Now I can't even unscrew the damn thing, it keeps turning both the cocking piece and firing pin... cake and biscuits!
 
I managed to get the bolt back together, however, the bolt is flush, the lines just don't quite meet... any ideas? I cycled the bolt without any issues, there is no binding or stikyness.

Heres how it looks at the back:
 
Here is a picture of the knob as the bolt is closed, uncocked, in the rifle.

Ok. I used my old Izhevsk Mosin Tool to measure the firing pin protrusion. It's sitting at about 80 (it is just a hair too long at 75 but well under 95 on the tool). Is this bolt safe to fire?
 
I have tinkered more, removing the bolt head and twisting the cocking knob... the lines now line up a little closer together, almost flus but till skewed. Ideas? Explainations? Is this safe to fire?
 
I have managed to align the bolt lines properly symmetrical, however, when I take a single dryfire and extract the bolt, the bottom line of the knob is rotated maybe .5 mm to the left, the top is still in contact with the top. A picture will follow
 
Relax dude .... It's a friggin' Mosin-Nagant for crissakes ! I'm assuming you have a Soviet-issue or possibly Finnish-issued cleaning kit .... Which comes with that big friggin' D-shaped "wrench" thingy with two notches in it.

The deep notch means "too deep", the shallow notch means "too shallow" (these things were made to be so simple even illeterate conscripts could understand them) , so as long as the firing pin when sticking out of the bolt is too deep to fit thru the shallow notch, and fits right thru the deep notch, you're fine. Just align the index mark on the cocking piece with the one on the firing pin, use the guage, and either screw or unscrew in half-turn increments using the guage each time and you'll figure out where the damned thing should be eventually ....

I don't have an M39 but I do have both a Russian 91/30 (basically an M39 without the fancy two-piece stock) and a Polish M44, and I have been known to mix and match bolt parts post-cleaning every now and then ....

The ONLY important bits are the firing pin protrusion, and the bolt head, as long as you don't swap bolt heads between rifles, and check the firing pin protrusion, things are safe and you didn't break anything.
