Are you planning on making one-piece hubs from scratch?

The splines are a British standard, shared by Austin Healy, MG and Triumph, and adapters are available from Moss, Dayton, etc. The only variation is the distance from the cone and the mounting flange. (I have specs on most of them, so if you give me some preferred dimensions, I might be able to come up with a close match.)
