For the table, I have a 3/4″ plywood base which is attached to the framework underneath. I then used this slat wall stuff from Menards, and inserted the aluminum strips in it and screwed it all down to the plywood underneath. So far I’ve been pretty happy with how this is working out. I was able to surface the slat wall so I have a perfectly flat working surface. The hold downs were made on the machine too, and I used a set of slightly modified toilet bolts with the plastic knobs for the bolts.
