Metallurgy advice


Recommended Posts

Following previous advice from the PW massive, I now always use silver steel for the various firing pins I have made and modified. Heating to cherry, oil quenching, polishing then heating to blue and again oil quenching has been totally successful. I have made for myself and also for friends, something like 30 to date, reviving many cabinet loiterers. 
my question is, would this be the same process for extractors? It would seem so to me as the only hard connection with anything is with the case, much as the firing pin only connects with the primer.

I should be grateful for all advice!

i do the heat  thing and tempering differently.....but if it works for you ...

what part of the extractor are you doing...? i ask this as the rod that enterers the extractor (on a  sxs) is silver soldered into position....so that will guvern the temp you will temper......

Most auto/pump extractors are stamped out of steel sheet and then hardened / tempered, Your way of hardening may work but I would only temper to a straw colour.

:good:

also make sure you know your steel..is it O or W...harden to non-magnetic

The thing would, surely, be in contact with the barrel? Or if an ejector and not an extractor it'd be in contact with the other extractor?

It runs into a machined slot but doesn’t impact steel to steel. The extractor spring allows it to ride over the cartridge rim and then keeps it in place when extracting. The ejector is a separate fixed block on the opposite side of the receiver which imparts a spin on the fired case, thus ejecting and releasing the case from the extractor.or in this case fingers which flip the case out

Ah so this is for a bolt action rifle (or bolt action shotgun) not a side by side or over and under gun? 

It's purely a guess, but I would put good money on it being for a PUMP Gun or a SELF-LOADER.    :cool1:

Yes, for an old pump gun that a friend managed to chip a corner off the extractor by not aligning the barrel correctly. (after cleaning he cycled the thing, thought it was a bit stiff so kept on cycling it! ) he admitted his guilt when I pointed out the damage on the barrel cut-out and the broken extractor. Hopefully will be able to repair ( he was going to put it in an auction to get rid!)

Ah! you know me so well! Another 37 saved (I hope)

I will be making him an alignment tool also!!

Aha! That the rear of the barrel is damaged and the corner of the extractor chipper tells me all I need to know. The original extractor was hardened. I'd harden in with a case hardening powder. Especially as modern cartridge heads (that it hits and rides over as it goes forward and then grips to remove them) are now steel.

Thanks for the advice! And apologies for not being clearer initially!
