Jim Legg, I have an Emco mini-lathe, just the handiest thing, I just turnd a pair of firing pins for a sidelock gun, how do you use the Kasenite? I do have a tin.

Mike I just follow the instructions on the can. I usually use an assortment called "fatigue proof" rods from Brownell's. I have also case hardened new firing pins in guns like the Ugartecheas, which tend to be soft from the factory. This seems to prevent the eventual mushrooming while not making them brittle.

Jim, which end of the firing pin mushrooms on the Uggie?. I did put a bevel on the rear end of the pins.

The big end where the hammer hits. Also the smaller front end can bend. Apparently lots of relatively inexpensive guns are shipped without hardening the firing pins.

Very likely the pins you refer to are made from steel of low carbon content (easy to machine) and will not through harden as will higher carbon content steel. Since they will work for some time, it is easy to see that a small increase in steel strength, such as produced by case hardening, will give you a satisfactory part. This also leads to the conclusion that unhardened O-1 and grade 8 bolt steel will be entirely satisfactory. Also, that properly hardened O-1 will be almost overkill.

In my experience,by far the best material for making firing pins is Drill rod [Silver steel in the U.K.] this centreless ground rod is available in a range of small diameters. It is usually possible to select a rod diameter that is close to the largest dimaeter of any firing pin you might plan to replace. The steel grades available ranges from from High Carbon to A.2.Tool steel. I use the high carbon steel because it is easy to harden and temper. Case hardening is not recommended or required for High Carbon steel.I think that the A.2 grade would not require any heat treatment because of the high alloy content when used as a firing pin.

Mr. Gruber,
The number of posts on this subject all point you in the same direction.Personally I would have been down the machine shop and had them made, and been out shooting by now.
