Do you have to use 2x1x1/8" tubing for a WCD?

This is a bit of an aside, but is there somewhere I can look up some detail on these specific bearing blocks?

I would just search CD. Everyone does them a little differently, and it's not hard to find pictures and advice.

We tried 1/16" wall tubing on an offseason project for a WCD. It wasn't terrible, but the walls bent in around the bearing blocks. Definitely would not recommend it.

1625 has a nice drive with wider tubes to fit their belts inside the tube. http://www.chiefdelphi.com/forums/sh...ad.php?t=86668

We used 3 by 1.5 by .125 tubes this year for our WCD. They were pocketed with 2 inch diameter circular holes. Rather than slide our bearing blocks rotated in place, having 4 discrete positions to both tension chain and achieve proper center drop. We did this because it moved fabrication resources onto the frame that would otherwise have been devoted to the bearing blocks. We also used the larger tubes because they work a bit better with the rivets our team favors. In short, choose a tube size that works for you, smaller tubes favor teams that weld and use smaller wheels, while larger tubes favor rivets and gussets with larger wheels.

Our team has used 1x3 1/8" the last 5 years.
