gunsmithing question?

Hi Militia,

It looks like I may need to fabricate my own replacement extractor for an obscure single shot bolt action 22 caliber c & r rifle (Pieper Bayard #3) that holds minimal collectors value.

extractor rotates on a pin in the bolt, pushed upon by a spring loaded plunger

question : are extractors typically heat treated / hardened ?
I am guessing no.

please advise

Hello Simon:

I am not a gunsmith, but for a .22, if made of a good modern steel, I wouldn't think so.

Would you be able to make a dimensioned drawing of the part? If it is a flat extractor I could have one wire-EDM cut for you, which might save you considerable time.

I decked a piece of D2 to .08" today and have given EDM your .dxf. Do you want more than 3 pieces? A loop and repeat program can make as many as you want within reason.

Everything will be cut to your nominal dimensions and you may of course need to hand-fit the machine bits. Let me know if you want any dimensions cut over or undersize. I will let you know when we're done.

Of course, being tool steel these will rust if you so much as look at them.

I hope this helps get your piece working again!

Cheers

Ken

I will check tomorrow on the progress; they were being hole popped today and will likely be wire cut tomorrow.

Re: your dimensions, 4 place decimals usually denote close tolerances are required. I told the EDM manager (who does handyman projects on the side BTW: many of his clientele are in Woodside) - THAT IS A SHOUTOUT FOR HIM - to not make a finish pass on the parts. I.E. the wire will cut the parts once with no second "cleanup" cut. I think you will be happy with the parts cut this way, but if you prefer a cleanup pass please let me know.

FYI we may do 2 to 3 cleanup passes on our high precision (and high $$$$ parts) for tolerances in the tenths or millionths range. I really don't think not doing a finish pass will detract from the function of your extractors, as they were probably hand fitted and finished in their original form.

Do you have any small "needle" or Swiss pattern files? If not, Grobet makes excellent files that can be bought from Western Tool, which has a store in Livermore. If you do not have any and don't want to buy them let me know and I will put my set in with the parts.

I mis-stated the material as being D2; it is actually O1.

It's feeling a bit like Christmas!

Ken

I am really enjoying all the knowledge being dropped here after asking but a simple question

* * * * *

I got reassembled and working another C & R 22 today,

a Stevens "Favorite" 1915 which is a lever action falling block single shot

I ebay'ed the replacement firing pin, which precipitated an internal disassembly to access the retaining pin, and a rust boil-out because it was apart already and needed it

new firing pin leaves good strong impression on snap cap test

Both of these rifles courtesy of my late FIL's arsenal
