Re: Poly Cord
Our lunacy bot used in house constructed PVC rollers (schedule 80) where the endcaps were drilled out to accept bearings and then it was glued together. To act as guides we sliced sections of PVC that had an inner diameter the same size as the outer diameter of the roller and glued them in place.
Last years roller claw used COTS aluminum rollers that someone found on McMaster.
Do be mindful of the span of your plastic rollers if you use them and how much tension they are under.
