Need unusual nipple

[zimmerstutzen]

As for what Southgate may have used, can't say. But I had a rifle with one of his barrels. It had an aluminum drum for the nipple. Never fired it. Don't know if that is the way he made it. Never saw another aluminum drum on any other gun.

Track Of The Wolf has three 5/16 nipples that use #11 caps: Part numbers are ERS-S (Parker Hale Enfield), MRS-S (Springfield musket)and MRHH-S (Navy Arms).

I filled the threads on my two Belgium pistols that I had issues with getting nipples. and recut threads with a different pitch. So far so good, I have about 20 balls down each pistol now and have had no issues, MAKE SURE THE OLD HOLES AND THREADS ARE PERFECTLY CLEAN.

any idea what PSI it can handle when cured?

No idea, but I watched my grandfather drill a hole down a crack between 2 cylinders in an tractor engine block and pressure this stuff into the crack until it oozzed out, let it harden, reamed the bores, honed the bores and put it back together. Two years later it was still running.

Loctite 235605 has a tensile strength of 2600 psi.

Loctite calls it Fixmaster® Fast Set Steel Epoxy.

That 2600 psi compared with brass @ over 40,000 psi and low carbon steel @ over 60,000 psi comes out "the small end of the horn", so to speak.

In other words, it is a weak substitute for metal.

I can't find the Locktite's compressive strength but I'm sure it is also very low. After all, even though it has some fine steel particles in it, it is still, basically a plastic.

Here's a PDF link to Loctites data for it.

When I cleaned the pistols after firing them, I removed the nipples and examined the threads. Still look great. No harm, no foul. Since I am shooting a very light charge the pressures can't be very high. Also, looking carefully at the threads, I can see that the new threads are engaging original metal.
Just curious, but what do you think the pressures are in the new "printable" 38 special revolver cylinders? Those are all plastic...

Find a good machinist to make you one.

I used to use a type of insert called “Time-Sert” on automatic transmissions back when I taught that subject at a trade school. They were more of a sleeve type affair and beat heli-coil hands down. Have installed hundreds of these and they’re the best. Industry approved for GM engines in their factory manuals.
