Four brass tubes were cut to 12" (30cm) long. This was done by simply lining up the brass rod with a ruler and keeping one end flush and moving the two together until they bumped into the wheel on the pipe cutter. Uniformity turned out very well.
Pilot holes were drilled in the bottom platform. These pilot holes served two purposes. The first reason was that the top and bottom platform could be sandwiched together and the hole position could be translated to the top piece accurately. The second reason, and most important, was to drill the hole from the top and bottom instead of drilling straight through. By drilling each hole from both sides there was no damaging hole blowout.
Holes in the top half were drilled to 3/8" (9.5mm) so the steel inserts could be screwed into place. These sockets had 1/4-20 threads which would receive a 1/4-20 bolt but they would not go all the way through wood which would have added an unsightly nut to the other side. This particular socket was driven into the wood with a 10mm hex key. Some use a flathead screwdriver.
All four sockets were installed into the top platform. Care was taken to not over-tighten them because that could damage the surrounding wood. No more drilling should be necessary.
After the drilling was complete it was possible to size the threaded rods which were longer than a standard bolt size. Brass tubes and two brass nuts were put on the threaded rod to get an estimate on the length needed. Several washers will also be used but their height is not as important so the rods would be sized generously.
Four threaded rods were cut to length with a band saw. Each end was ground smooth on a grinder. Recently the hack space acquired a mitering cut-off saw which might have eliminated the need for some of the grinding. It will probably be used in the future.

Half drilled at 1/4" (6mm) before drilling from the other side

Partially drilled hole to receive a 1/4-20 socket
