Precision Engineer Advice Required

[johnnytheboy]

The locking bolt on my semi auto shotgun has broken, I think this part might not be replaceable from the vibes I'm getting. It's the bit the drill is pointing at. I wondered what would be the best way to repair this. It looks like it's machines out of solid steel of some sort.

I would be very surprised if a major component like this would not be available as a spare, what make is the gun?

looking at the break, it looks cast rather than machined...If it is cast speak to a gunsmith, any decent engineering works would be able to machine a copy

how come you cant get parts?

It's a Russian baikal, friends had said it was doubted I could get one, and there maybe a long wait if it is available, I have found the parts diagram and asked my local gunsmith if I can order one. However, it's the middle of blooming shooting season �� Could be doing with a repair.

Sunndog, it does look like a cast break but it isn't, it's defo solid machined steel, I thought maybe a weld or something

Super glue it together, drill and tap a countersunk hole, locktite a countersunk screw in place.........job done....maybe.

Weld it back together and file it carefully to size. I've done it with no ill effects so long as it's not a pressure baring part, and it's not

Baikal have been common over here for years mate, i bet you can get a replacement pdq

 

[mick91]

Managed to weld that no bother with stick. Runs sweet as a nut now. Not know anyone with a TIG set? Be able to get that perfect

I know a gunsmith here in Derbyshire who can sort that for you, PM me for details if you want to talk to him.

This is a pressure loaded part, the action bar slides back under the bold locking mechanism hits the bit that's broken off which releases the bolt to eject the spent cartridge, superglue might not cut it lol but weld might!

As Sunndog says, Russian and Turkish guns are very popular, I'd be surprised if a gunsmith or dealer couldn't get a new part.

I rang the importers, lucky for me they never had me on hold when they were discussing this! Sometime never I think might be the quoted delivery from Russia! I think an alternative fix will be the order of the day!

Mick91 's I've seen in person. I'm an engineer by trade and thought drill and tap would be the order but he welded it and it has held up perfect for about a year or something now. I'd give it a shot

 

[johnnytheboy]

I turns out through months of emailing and chasing this, parts are simply not available for these guns!

My mate welded it, it's a non corrosive alloy, god knows what but a cracking weld job considering

 

[Robbi]

Nicely done !!

Shoot it with care.
If I read it correctly, that lug is part of the delayed blowback and will be taking the full pressure in the chamber.
If the weld gives, then the bolt could come back before the chamber pressure has dropped. That that would probably rupture the shell casing. You would probably only get a blast of gas from the ejection port, but there could be bits of plastic blown out too. Also there could be some venting around other parts of the action, which could come your way.
I strongly suggest you only shoot with eye protection and avoid loosing one off with anyone stood to the right of you.

It's the bolt lock, there is a gas operated mechanism that activates first from the fired cartridge that then unlocks this bolt and takes this bolt catch and the bolt itself backward ejecting the spent casing, it all happens after the firing event so it's plenty safe enough!
