One advantage of the glue is that the layer is very thin and quite rigid. A layer of tape will be slightly flexible and so might cost you a bit of precision.

I'll try the tape-glue-tape system some time. Sounds much more convenient than have to soak or cook the glue off.

Most cyanolacrylates reach well over half their ultimate strenght in 10 minutes. No need to wait 24 hours. They do not release cyanide. Some people are allergic to the fumes but most just find them noxious. I'm allergic to bananas but I don't claim they're toxic. I've used double-sided tape. It work...

I've never done it either but the melting point of copper is above the boiling point of zinc so you certainly don't want to melt the copper first. The melting points of those alloys are a bit below the melting point of zinc so I should think that melting the zinc and dissolving the other metals in i...

Don't know.

Goop that stops soldering or brazing metal from sticking.

Perhaps coat the carbide with anti-flux?

I've got a 100' 12 gauge extension cord that works fine. 3 volt drop at 10 amps. You may have branch circuits that long.

Interesting design. Is the casing extracted by pushing it out?

Mount a cartridge on the lathe, centered between 2 formed rods [drill a hole to hold the nose and round off another rod to fit into the indentation at the rear]. Then put a dial indicator on the top slide and run it up and down the tapered side of the shell, adjust the angle until it's right. Then ...

I've successfuly used easy-outs for that.

What's an internal pipe wrench? Sounds very useful.

One way to make such tools is to start with an HSS drill bit.
