Thanks to everyone for their suggestions!
Shersta: Elegant solution, having a machine shop point the rods. Could you still thread things on at that end? Don't suppose it matters too much.
Jdubs: My noodling around the web found only 3' and 6' rods. If you need 4' and go with steel of a reasonable diameter, it might not be prohibitive to get 6 footers cut down. I expect a good shop could re-tap the threads at the cut end, too. How many shelves do you need? You might be able to put 4 on 3' rods, depending on shelf and gear thickness. The design is so open, I doubt cooling would be an issue.
Dbld: I'd just picked up a scrap of sheetmetal to make a template as in Richard's helpful instructions, but I like your full size template idea too. Question: why should it matter if the holes in the template match the size of the pilot on the bit? Mightn't one drill the hole to match exactly a center punch, mark all the holes on the piece with the punch, and then drill it? Seeps like there would be next to no slop that way.
I might well be interested in the cherry, depending on timing, etc. I'm now in St. Louis, but I'm through PA a lot, for work and family. Feel free to email, jdoris@artsci.wustl.edu
