Re: Tubing for ball intake
To share our recent experience with the McMaster 1" belt:
http://www.harborfreight.com/130-wat...ife-60313.html
This hot knife along with some clamped angle iron works wonders in joining the flat belts quickly. It's probably overkill for the solid core round tubing.
Also, I've seen a ~10% length reduction recommended for proper tension. This may be feasible for the small diameter round tubing, but you might find that stretching the flat belts that much makes intake assembly, well, difficult. I'm finding that we have sufficient belt tension by simply ignoring roller diameters.
