Hinge pin shim material

[Bill Graham]

When shimming to bring a gun back on face, and a piece of aluminum can is too thick, what do people tend to use? Eventually it might be repaired with some TIG welding, but for now a shim needs to be the solution.

Shim material sold by Brownells.

Or an oversized roll joint can be installed.

Thank you. The solution needs to be one I can perform myself, and this sounds like a significant repair left to the truly skilled. If it's not that difficult for the hobbyist/student, where do you find an oversized roll joint?

How about a feeler gauge?

[B. Dudley]

Exactly frank. You can cut off a piece of whatever thickness feeler gauge material you may need. It can then be annealed to remove the spring from it. And then soldered in place. It would need to be soldered in with a very low temp solder like Tix in order to be able to get the solder to flow on the thick barrel lug.

In regards to oversized roll joints. They come from me. I have them pre-made in 3 over-sizes ready to be fitted to the gun.

As for any hobbyist refitting barrels. Any method used: be it shim, welding or roll replacement, the hook and breech still need to be re-fitted after the addition of material is done. It is not a matter of just slapping in a shim and calling it a day.

Most auto parts stores carry or can order shim material, just tell them how thick it needs to be, if you know a machine shop they may give you a piece of shim material for nothing, check it out. It is usually made of brass, easy to solder.

Thin out the beer can section with a file or sandpaper.

stick the shim material to the joint with Loctite 380black max. you need to use something with the radius of joint to hold and press it in place till it dries. Brownells has the Loctite or you may find it in automotive stores. a large drill or piece of rod to hold the shim in place with pressure.

Purchased a set of feeler gauges from an auto parts store. Roughed up the mating surfaces. Used Devcon as the adhesive. Held it in all place with a 3/8" drive socket extension wrapped in masking tape, wood blocks and a c-clamp. A small amount of sanding with a dowel wrapped in emory cloth was all that was needed to finish the fit. Tight on face, no shake, all is well.
