I just changed the motor to a 3hp and belt sheave to have speeds and torque from 50 rpm to 5000 rpm. Though the testing last evening to able to drill a 1.125 with a drill bit( 7/16 pilot hole) though 0.250 304 stainless plate with no hesitation or stalling of machine. Video and load meter stayed in the middle to lower part of load meter. Machine now has no hesitations when drilling 0.500 holes in stainless plate ( drilled a lot plates last night) May make kits avail if any interest out there.
