Supporting the tabletop would require sturdy support from below. More 2x4s would do the trick, and plenty of mounting hardware would fasten them. Four sections were cut from the lumber, each 30” long (0.75m). The first supports were wide-angle braces, and their mounting pattern was marked at the base of the 2x4s.
Angle braces and their holes

Right angle braces supported the joint between the base and table leg. This part would likely have the most stress and therefore given the most structure. The included screws were the only ones installed. Longer ones may replace them if it seems necessary.
Sturdy feet

The base began to look like a crude mock-up of a starfighter and was already more electronically advanced than some movie props.
Upright struts in place

The table legs flexed inward a bit so when the T-shaped braces were attached, they held tightly without clamping or extra support. A final measurement showed that the top was higher than a standard table.
Usable table with a hole

The hole in the middle of the octagon was 11” in diameter, but this was a conservative guess based on my recollection of the motor array. If it was wildly wrong, the hole could be shrunk with a holed-plug, or widened with a jigsaw.
Exposed post

One of the shop chairs was tall enough to make the table look comfortable. Nurse scrubs are excellent work shirts. They are durable, have pockets, easy to wash, and inexpensive enough to replace.
"You may be wondering why I've asked you here."

Ball transfer units from the surplus store used the same 1/4-20 mounting shafts, so I bought four and installed them in place of the feet. This further raised the height of the tabletop but make it a simple task to move the base and table across a smooth floor.
