These are some adapters I had Alex Meade make up so I could mount a mid BB shell in my HJ Universal jig. They have a side benefit in they keep the shell from warming too much when I weld. I use OA welding on my BMX bikes and that really throws a lot of heat. They fit perfectly first time out.

FWIW you **can** use the HJ cones to set up a Mid shell, just barely, but you cannot reach the setscrew that holds them in place, so it is a little iffy.
