Just for closure- first batch we're getting cut off at a supplier, who
also happens to have a ratty but compact guilliotine-style (two post)
bandsaw for sale that can do it in two cuts. Asking price for the saw
is $2K.


Okay, here's what we actually ended up with and what it looks like.

Cost more than expected (about $5K), and looks pretty ratty (had to
replace the
tachometer and the shutoff microswitch) but it works fine. I put a
Tachulator
on there with a divide by six and Omron proximity detector to count
the spokes
on the 16" drive wheel so it reads SFM directly (showing 295 feet/
minute). The
Telemechanique microswitch was obsolete, but available off-the-shelf.

It'll last for about 100 more years the way we use it.

So you are making gargantuan woodruff keys?

I suppose you could call it a "key", but to what I cannot say.
