please start a thread on this. we are curious. are they bonded, welded or ?
where did you get them?
Turna beat me to it as far as my build thread.
The rims are interference fit by 0.010 of an inch. Cool the center down to shrink it and heat up the hoop to expand it. When they get to room temp they're stuck together. I'm having someone TIG the entire inside perimeter to keep it locked together.
