This little milling spindle is still working well after years of use, and among other things has cut many gears. Due to me requiring a range of speeds I designed a slightly larger spindle, using conventional bearings, a No1 Morse taper, and a three stepped pulley. This has further uses and can be used on heavier work. A small taper shank 1/4 inch Jacobs chuck, and No 1 taper shank drills, enable milling and drilling operations. I have been impressed by its versatility.
