[Healeys] Steering column issue

[john spaur]

2. Use silver solder because if you powder coat the box it has a 
higher melting point than regular solder. It would ideal to have a 
melting point greater than 450F. You can use a propane torch with 
MAPI gas. Clean well, tin the tube, use plenty of flux, assemble and 
heat until the solder is drawn into the fitting.

1. You might need a mandrel and press to put the groove into place. 
You might be able to solder a washer in the tube to act as a seat or 
use cooper wire solder in place.
