To rebuild or not?
I bought a 1941 Maltby recently, and the bolt was I'll fitting, and basically stuffed. The barrel is good+ and 2 groove. The rifle shows CHS with a different bolt body and a 0 bolthead, but none of my (very few) bolt bodies are a good fit to the recoil lugs. So to set the rifle up, I'm looking at having to stone the main lug to set the bolt up.
I've read Peter's articles on the topic and think I could get them both to bear, but is the likely outcome that I just stuff up another bolt body?
I suppose I could wait to find a bolt body that fits off the bat, but I'd like to use what I have if possible rather than have it cost me more in parts.
Cheers.

stone once measure twice. Build up then stone back. Hard facing is a factor with heat. Your rifle your call how fast you procede.

This is the problem TBone............. Is it the body or the spare bolts that are worn? We had the GAUGE bolt to tell us if it was the body and a big box of bolts to try. Stone the best fitting bolt to get a perfect bearing on the locking lugs. THEN CHS it up. If you've got to use a larger size bolt head, so what?

I can stone one to fit, and I'm sure I'll get CHS with a selected bolthead, I just wondered if I'm likely to go through the hardening and stuff the bolt. I've re read your article on the topic today and I'm sure I can get the fit right, but was this process as common as say stoning a trigger to get correct let off? If the bolt hasn't been stoned before, am I likely to damage it by fitting it like this?
It's just a new process to me and I don't want to engage in too much "destructive learning" where avoidable.
BTW pretty sure the body is fine, no bolt body catches the sear with the small locking lug, and all headspace with small boltheads (except the one that came in the rifle which catches and won't headspace). Also I noted that the original bolt, has a bolthead that won't index right on any other bolt I've tried it in, by about 30 degrees, and any other bolthead won't index on this bolt body by the same margin... weird... Did they ever change the start position or something?
