Still looking for a 'worm transmission' after all these years.

Try a jackshaft - it's a lot more obtanium (and adjustable) way to slow
things down for the home shop budget.

But McMaster will set you right up if you like - try "speed reducer" -
$300-500, with a few outliers above that range. The right angle kind are
worm gears. Page 1014-1015

Or these days, a VFD - you might easily get a 1-phase-in 3-phase-out VFD
and 3-phase motor for less than a speed reducer, and have variable
rather than fixed speed available. Just depends on how you care to go at
the problem (and whether you have 3-phase handy, so you could just use a
3-in, 3-out version.)
