View Full Version : Welding Gun Parts
02-17-2004, 01:04 PM
I am getting into gun repair sort of by default. I mess with them and then they need repairs....I need some recomendations for what would be the best tiny sized welding torch or device for welding steel shims about .006 thick to gun parts that are maybe 1/16" thick and less than an inch long.
Does anyone know if these propane micro torches that will supposedly heat up to 1400 degrees F gets hot enough to weld the sort of tiny stuff I am interested in working on?
Will I have to kick out a bunch of jing for a jewlers oxy-actelene mini-torch and regulators, etc. to get what I want?
Send me your advise and recommendations, please.:cool2:

i would say a tig welder, but if you are only doing this as a hobby tig much not be worth the cost, a typical low end tig set up is 1500.00 (new) go to a local welding shop and see how much they will charge you to weld em up.

What are you trying to do?
Typically you would Silver Solder Shims.

You won't weld steel at 1400 degrees F. That takes about 2300 F, give or take. But at 1400 degrees, you should be able to silver solder or brass braze, at least with many of the filler metals. That will provide more strength than you'll ever need for parts that small and the finished appearance should be a lot better, also. Just make sure the work is as clean as a hound's tooth first. Remove any bluing, oil traces, etc.. Use a microtorch with brazing or silver solder flux, depending on what you select. Radio Shack used to sell a microtorch with two CO2-sized gas cartridges. I don't know if they still sell them.
All BAg filler metals are suitable for carbon steel. Those that contain some nickel have better wettability and should make a good joint.

Thanks for the feed back to my question.
Fly Jim wanted to know what kind of parts I am working on. Typically, with 80-120 year old revolvers, I find that the "hand" and "pin" parts that rotate and hold the cylinder are worn down from use. Getting new parts is usually out of the question...even used parts is sort of skoosh...so I am gearing up to be able to weld on one drop of steel (nickle steel rod at 3.5% is avaliable from Brownells) to these tiny parts. Then I can reshape them with files and install. This is the way the real pros do it according to Nonte, and he wrote the book on pistol repair.

Are these "colts". or foreign guns. American guns, such as old S&W's or Colts and a lot of others.have a lot of parts available from "Dixie Gun Works". I got a set of screws for an original Colt artillary model from them.
If you have to repair a hand. I think that a better solution would be to fabricate a new one out of tool steel available from Brownells, using the original as a pattern, and make the contact points a few thousands larger. (I'm assuming you want to have these in shootable condition.) You would then harden the part, then stone it to size to time the revolver. Be aware that if the revolver is collectable, replacing or modifying parts greatly reduces the value of the firearm.
