Bluing a Swedish Mauser bolt assembly?

[Lashenden]

I want to reproduce the blued bolt assembly from the M41B (don't worry, the donor rifle is already a mixmaster!). Anyone tried this?

Do you mean a hot blue or what exactly? Hand blued?

[Lashenden]

I mean whatever will match the existing in the white bolt with the receiver, a la M41B. I expect this will be a professional job as I don't have tanks.

It will depend on a few things out of your control. Usually one would blue the whole affair so it matches, one part will show different.

I believe I read somewhere that the Swedes used a salt bluing process initially then started using Dulite hot bluing in the mid 50s. I'd go with a hot bluing process, but probably doesn't really matter with a repro rifle. I wouldn't spend much money on it myself. You could rust blue it yourself and come close with minimal cost.

Careful doing a nice rust blue, it'll turn out so nice you'll want to do the rest as well...

I had to recreate some rings for my k98k double claw shooter (not historically correct) so as you can see the rings start out in white. Needed a hot oven; I used my on the stovetop pizza oven and spun past the top temperature 850+ F!!! Yikes. Get the fire extinguisher. After 45 mins of heat then dipped in 20/50 weight Castrol oil. Turned out pretty close to my German rifle. My friend used a blow torch on his small parts but they never turned out as good. I have blued screws, side base mounts, top base mounts etc and they all do really well.

All useful info. The bolt is being bent soon, so maybe that's the time to do rust or oil bluing. I'm assuming that a normal oven couldn't heat the bolt to a level that would affect safety? This is an old replacement bolt of uncertain age, after all.
