I got plumber friend to source me a piece of 150mm PVC pipe + end cap, cut the pipe at an angle (10cm drop), drilled a couple of holes and then made a crossbeam of dowel covered in PVC tubing with chair leg rubbers as end pieces/shockmounts. I cover it with a small plastic bag when not in use to reduce odours.

We own one of these. I am contemplating building some for friends as gifts.
It is just a small rectangular stainless pan about 2 inches deep. They drilled a hole on each side and ran a 1/2 inch threaded rod through it with a nut on each end. The 'knock bar' rubber piece is just a piece of high pressure hose cut to length with the rod through it.
The frame is a simple wooden frame a bit deeper than the pan, and the pan just sits in it...just lift out the pan to empty and clean. It has been being knocked about our counter for a couple years now.

Your friend does nice work short_black! If I were you I'd put some rubber around it, because a PVC pipe wouldn't absorb any of the shock. You might not dent the wood by hitting it directly, but I'd think over repeated heats you'd still have a chance of cracking it. Rubber would help ameliorate this a bit.

short_black, if you look at my effort further up, you will see my bar is covered with a piece of clear hose. This cushions the knocks and keeps the wood clean. If your bar is not removable, you could slit a piece of hose so it wraps around the bar. It will look nicer than PVC pipe, too.
