That's 2.5HP input -- I wonder what the effiencies of a motor that small are? Even if it's just 50% efficient, it'll probably twist your 7x10's spindle into a...

It's unlikely that you'd ever run a 2.5HP motor at anywhere near its full power on a small lathe like the 10x7 -- you'd likely brake the belt, strip the keyway...
