The other day I bought a rebuilt RS Duke fork of Craigs for cheap to use on a beater mtb I'm building. When I was installing it it didn't have brake studs installed. Found a set in the junk box. First one goes in fine, second balks with about one turn to go. Lean on it just a bit and the entire boss breaks off. Turns out the hole wasn't drilled quite deep enough and it bottomed out. Previous owner used disks. Now I figure I've got to turn this bike into a mullet. More $ into what was supposed to be a cheap bike. The broken section looks ugly so I grab the JB Weld and glue it back on. No way I'm riding this, right? I know JB is strong but all I can imagine is it letting go, brake arm swinging into front wheel, going down hard.

Is that a product or are you talking about actually welding? I didn't think castings like this welded very well.
JB Weld is glue. I wouldn't trust it myself.

Drill bit and an easy out.

It wasn't the brake stud that broke. About 3/4" of the threaded part of the casting separated from the main body.

Have you considered swearing?

Either completely disassemble it and have it welded or use disc brakes. Jb weld and other epoxies are not suitable for this You might be able to figure out a mechanical clamping arrangement with something that goes all the way around the shock tube, but it still would be marginal.
