I seem to recall but can't find a post explaining a simple repair to a high wall firing pin. It may have come from JD Steele shortly before he died. My problem is to replace the tip and maintain its temper while fastening it securely in place. Any help will be much appreciated.

Bill,

Not sure what JD's technique was. But it is possible to drill the pin (on a lathe) and insert the appropriate size(press fit)drill rod. No tempering required.

Bill,

I tried to find my high-wall parts but no luck. I did the the very thing Ken said and I'm sure when I pressed it in there was a little red loctite.

Speaking of high-walls now that I have lost my friend and gunsmith I am clueless as who could barrel a high-wall for me.

I need someone who UNDERSTANDS how to to find the proper placement for the main (flat) spring. I can even supply the fixture for this.

With all the down time I have been thinking of all the projects that I have backed up and it's daunting. Any Borchardt folks you would recommend to install a set of Zischang DST? I know we all look at these things different and if you would like to make private recommendations that would be fine.

MP,
Without a doubt one of the very best persons to rebarrel a highwall is right here (at least sometimes). Glenn Fewless understands how to barrel a highwall like few other folks. He can fix your pin too. Lots of methods for doing that. Drilling it out and replacing the tit with a roller bearing, S7 Steel, or spring wire are all well recommended by many accomplished shooters.

use stress proof or fatigue proof steel
no heat treat required
drill rod ( o1 or a2 etc) is too brittle and will fail over time



I prefer to set up in lathe (made a 5c collet with clearance for leg of firing pin) and face back around 1/8 inch then drill hole bigger than firing pin and make press fit pin
with shoulder same diameter as old firing pin and then smallest diameter to go through breach face ... simpler than it sounds and very strong.

Thanks I had thought of Glenn a while back and now that you reminded me a good idea.

My pin is fine ;-) as a matter of fact my high-wall action has a Mann-Niedner pin.

Piano wire will work for you virtuoso's.
I like like M-N pin!!!

Thanks to all who replied. I cut off the old tip, drilled out it's base, fitted a new tip of drill rod, and Loctited it in place. When it fails, I'll follow Harris' advice re alloy.

I have used RCBS decaping pins for replacement firing pins a trick I got from Bob Snapp.
