Go to Post I'm impressed and incredibly amused that you found so many of Dave's evildoings, though granted, they aren't that hard to search out. - DCA Fan [more]

Re: Polycord stretchers

Quick Connect Round Urethane Belting is quite easy to handle. It has the downside of snapping once every competition if you don't check that the quick connects are seated every match. This downside is greatly mitigated if you pay attention to the minimum pulley size.

You can't tell this from the mcmaster site, but looking up the part # that's printed on the belt led to some spec from the manufacturer in 2012 that said 3% stretch is optimal for this particular cord. We measure the belt length using string, then divide by 1.03. Following mfr's spec with this belt is key to it success in FRC - an overstretched belt will cause extra load on the motor, just like a pulley that is too small.
