: you know, it's interesting... i dont think pvc epoxy (the stuff that plumbers use) is listed in the goal construction, yet we went ahead and used it anyway. If the goals in competition are going to come apart as easily as ours did before the glue, that could pose a real issue. just in dragging ours around, they came apart.

For goal construction and PVC joints you don't want to have come apart on your robot use PVC cement from the hardware store. Epoxy doesn't bond well to PVC.

Last year we had a few joints on our ball hopper that we needed to be able to take apart in case of repairs. For those we found a self tapping screw through both the fitting and the pipe worked well. Just be sure the screw hits both!

As Ed Sparks points out, both are considered fasteners and are therefore on the additional materials list.

Take your Pick
