I have a 1956 14" Delta Bandsaw that from the Factory was made to do Wood. This same Model with an additional Gearbox allowed you to slow it down to under 200-FPS so It could do Steel as well.. The problem is that mine does not have this Gearbox and I want to use it to do Steel only.. From reading I find that in order to do Steel the Blade must be moving at under 200-FPS (Feet Per Second) - The current AC Motor runs at 1750-RPM and has a 2" inch OD pulley on it.. The Saw now has a heavy cast-iron 11" OD Pulley on it that replaced an 8" inch OD unit.. The "tires" or pulleys inside the housings that drive the blade are 14" inch OD and are on the same shaft as the 11" inch one.. I know that I need either a gearbox to slow down the Motor itself or a jack-shaft setup to slow it down.. or someone mentioned a "Variac" to change the speed of the AC Motor itself.. any thoughts as to what size I would need for pulleys? Or what ratio of Gearbox I could use on the Motor?
There is two Videos on this Saw that I have been restoring: #1

Understand that they do not show the 14" inch pulley just yet.. or a jack-shaft setup #2
