The motor/gearbox assembly is bolted to a pair steel angle brackets (with bronze bushings) which in turn slide on a pair of drill rod "ways." Belt slacking and change is achieved by moving the motor/gearbox chunk (and thus the driving V-pulley) forward or back by a leadscrew down the middle if the ways. I am currently in the process of completing a belt slacking mechanism. I then pieced together a pair of 3-step V-pulleys which most nearly gave me the range of blade speeds I needed and luckily everything worked out so that I have a range of speeds I can live with. I already had a Dayton 3/4hp/1725rpm C-face motor. I then began monitoring eBay and quickly picked up a new NEMA C-face 90-degree reduction gearbox for a pittance. There were dozens of possible combinations. In proceeding with a conversion the first thing I did was figure what size pulleys, gear reduction, final rpm, etc, were required in order to end up with something within the blade speeds I needed. This is still a made-in-USA cast iron machine and has decent bones, except for the blade big wheels which are aluminum (although on ball bearings.) A while back I picked up a virtually new Delta #28-245 14" vertcal wood cutting bandsaw for relatively cheap.
