I replaced my motor with a new 3/4 hp 110v motor from Grizzly. ?Seems to run fine. ?220 would be better from a harmonics point of view - but 110 is more versatile from a small hobby shop point of view. With the Dalton spindle bearings, I believe the recommended setting is no more than .002¡± vertical movement on the spindle- measured with a Dial indicator, by properly shimming the bearing stock, tightening the bearing cap bolts, and inserting a bar into the headstock and pulling upwards. The bearings need 2 thou or less to hold the lube oil. ?Anymore runout will cause the work to deflect when taking a cut. Less, causes excessive wear on the bearing material and or machined shaft surface. Glenn B. Hi Larry ? Using the Dalton supplied countershaft three step pulley Dalton ran there countershaft at 250 rpm.? This I believe gave a top spindle speed of 480 Rpm.? You would be safe at running your counter shaft at 350 rpm. This would give you a spindle speed of around 700 or a little more.? With drip feed oilers for the spindle bearings you can run up to 900 rpm safely.? Would not recommend running your Dalton spindle any faster than that. ? Dennis ? ? Sent from for Windows 10 ?
