Re: Polycord Slippage
In the past, we have used PVC pipe (1-1/4 size, which is 1-5/8 OD) and then used the couplings as cord spacers. With 3/16 cord, we had about 5/16+ spacing.
Using bearings in the ends of the rollers helps considerably. There is a lot of tension on the tubes from the belts, and having a solid rolling surface for the bolts / axles is important.
We have used a 90% belt size in the past with no issues. They are tight, but stay tight through the season.
