Well, keep us posted! I bought some greaseless a few years back in the heyday. Never got to building something to use it with, though, with exception of some little felt wheels for spines, tangs, spots, etc. Seems to be happy in the shop fridge, sealed up.
Some day, I will get something going. I have inherited a variable DC motor setup which I think will work. Just need parts and time.
Same age-old problem! ;)
