I am gathering a list of people interested in plans for an expanding table with a metal mechanism. It will be based on the metal prototype (see posts below) but with simplifications to minimize tool requirements.
Please click the “Table Plans: Metal” button above-right for more info.
I also ran a test on Delrin (acetal) for 15,500 cycles. The weight was also increased as I thought that the contact area was larger, though this was incorrect, as the last photo shows. Dimensions were essentially unchanged, within half a thousandth of the starting value. Very slight squeak/creak sound later in the testing but definitely a good choice if looking for performance between nylon and UHMW.
