Re: polyurethane tubing

We used the 3/8 inch, clear, hollow core tubing and joined it with the barbs. We have had the barbs pop out, so we added duct tape after that incident, and haven't had any problems since. We are also using 3" diameter plastic pulleys for the 3/8" belting.

I had to manually create a key/set screw hole in 2 of our 4 pulleys on the drive shaft, but it was pretty easy to do, even with a hand drill.
