1917 Spandau. Will be used for a warmly loaded modern round. Should I send it off to Salt Lake before I d&t, surface grind, reshape the tang, etc or after? This is the first action that I have considered heat treating.

Also, I wasn't going to treat the bolt. Should I? Thanks a million.

Others in the past have indicated that there is a possibility of warpage if you case harden first. Call Blanchard's and ask them if they think you should anneal the action first, do the work, and then reharden.

That's what I would do.

Use a VZ/24 action instead.

Depending on how they HT. If the final hardness is no more than 40-45 Rc [that's how they should do it] then it would be better to machine after HT to eliminate any warpage problems.

I've always done my clean up & machining first and never had a warpage problem.

IMHO, warpage has more to do with the method than with what you done to the action.

I guess I was wondering about scale developing in small screw holes etc. with the re-hardening process. I'll call them--
Would you re harden the bolt on a WW1 action?

Of course you need to give it a final polish afterward but that is an entirely different thing than machining it afterward.

YES.

What is the name of the company that you send your action for heat treating. I have mauser that I am working on and need someone to heat treat it for me. Any help would be greatly appreciated.

Thank you

I just recently recieved back a 1909 Argentine that I sent to Pacfic Metalurgical in Kent, Wa. Turnaroun time was about a week. The action is now 36HRC and the bolt 47HRC. No warpage, but there was a small amount of scale that had to be dealt with. Website www.pacmet.com.

Craigster how much did it cost?

Doug,
It was $85 plus shipping for both pieces.

Not an action I would use, but to each his own..I would anneal the action then have it brought back up to specs, thats the only way I would do it...
