View Full Version : Polishing a Turd

I had my Mosin's bolt apart recently so I could clean and lube it, and I noticed several things. First, the firing pin was bent in at least three different places! What was Ivan doing - using it for a tent peg? This has also caused the firing pin hole in the bolt head to become slightly egg-shaped. Hmm... Okay, I know a good machinist who will make me a tool steel firing pin and heat treat it for free. That particular problem is solved! I carefully examined the firing pin hole, and it isn't that bad - unless I start having primer material extruding into the hole, I'm going to call it good.

Then I got to examining the bearing surfaces where metal meets metal. :uhoh: OMG! It's a wonder these rifles function at all, as rough as these parts are! Having entirely too much free time and virtually no adult supervision at work, I decided to do some work on it. I began by slowly and carefully filing down the worst of the roughness with a very sharp Grobet Swiss pillar file. Not removing any metal per se, just smoothing things up a bit. Then I stoned the worst of the remaining roughness and tool marks out, and then lapped the parts together. This was primarily where the bolt head, bolt body, and connector interface.

I polished the back of the bolt body where the cocking piece rides with my Foredom tool, and then cleaned everything in the solvent tank. A bit of lube, and now I wait for the new firing pin to come out of the heat treat oven and cool down before reassembly.

It's still a turd, but at least it should be a more smoothly operating turd! I would post some before and after pix, but cameras aren't allowed at work without special authorization (yeah I know, everybody has a camera-phone). Disassemble your Mosin's bolt and look at how rough things are, then imagine them a whole lot smoother. That's pretty much how it looks.

Mines not to bad really, had to take it apart to get the cosmoline off. Probably depends on when it was made. With what, 17 million made I doubt they cared. Mines a 1929 ex-dragoon. For $109 out the door I wont complain about anything on it LOL

Mine is a hex receiver, numbers-matching 1925 Tula ex-Dragoon. Of course, it's been arsenal rebuilt at some point in its life, as evidenced by the small repairs to the stock and the Izhevsk parts on it.

I suspect that the bolt parts that I mentioned were wartime production, because the rest of the metal work is much cleaner. Those parts were obviously made under great pressure for time, and the milling was done with dull end mills.

After assembling the bolt and testing it in the rifle, it does operate a bit more smoothly. Cleaning the parts up was a productive use of some downtime at work, at any rate.
