Treadmill Motor Conversion On A Walker Turner Drill Press

alright, next project on the list - adding a variable speed treadmill motor and tach to my WT drill press which also doubles as a sort of mill. It currently has a 1/3hp motor with 5 step motor>intermediate>spindle pulleys to give 250-900rpm and 3000-5000rpm. Changing belts in the lower range isn't a major deal, but it's enough of a hassle that I'm almost always using the wrong speed for something, and that gap in the middle is a huge pain.

I got a 1.5hp treadmill motor and MC40 controller...
