Wise words EC.
To automate the welding wouldn't be difficult, and once the setup parameters are recorded and test welds done and tested at those parameters repeatable good welds would be possible, assuming the cutting was equally accurate too of course, the edge should be machined true for automated welding.
I've quite a bit of experience of automated welding, no intention of banding wheels though.
I have a funny feeling that nobody would want to pay for the quality if someone did it.
I have heard of this company -
who can have wheels made to order, the prices look very good. I wonder if they could supply rims only in the right width to have welded to your own centres?
