There is a hexagonal box around the center of gravity of the telescope tube. That was hard to do. I thought I had the table saw set to very close to 30 degrees from vertical (with a precisely cut piece of cardboard) and I thought we were getting 0.01 inch precision on the length of each cut, but the box was a bit too big, and the angles didn't quite close up. To compensate for the size being too big we cut two sides a bit smaller, and we shimmed between the box and the tube where needed. Here is the hexagonal box drying, held together with a giant rubber band (red) and Duck tape (silver).
1/16" bondable PTFE pads to the sides under the rockers, and used the rockers themselves to press the pads down. The clearance is pretty small--we'll see if any problems develop as the wood ages.
