One thing I thought which was interesting and never realised was that the butting is done by grinding down the outside of the tubes.

The other way is to take a sheet and thin the center (by drawing perhaps), then roll, then wield. AFAIK this is the most cost effective. Leaves a seam though.

Saying that the 6/4 tubing wasnt seamless, and they did'nt seem all that bothered about that. I always thought seamless was the real deal. No reasoning behind that though.

I remember when looking into XCAD options for a road frame. A lot of internet experts (or scobles) were pretty down on seamed tubing. It was assumed any butting preformed by XCAD would be via sheets.
