Where did you get 7500 fpm on the band saw? Normal 14" bandsaw runs
about 3000 fpm MAX. (Mine is set for about 2500 on wood) And 200 fpm is
fine for bandsaw work in steel. So 12:1 would work fine. NOt 100:1

The ratio between wood and tool steel is at least 100:1 and your
vari-drive definitely does not have a speed range like that. You are
going to need a gearbox or chains and sprockets to get down to 60 SFM
from 7500 SFM as used on wood. I am not trying to rain on your parade
but just being realistic. Leigh at MarMachine
