chipenter:
Drilled and taped for the idlers and motor mounts , got to figure a way of joining the drive belt all I have come up with is gluing 2 peices back to back , make some feet next now I know the height .
chipenter:
Time to fit a motor a peice of 2 X 1/4" black iron was mounted , and slotted for the motor and driled for the spindle , the ends were radiused , started turning a peice of 2" bms for a spacer before the temperature droped like a stone with the sleet shower .
chipenter:
Turned a spacer to go between the motor mount and the spindle , just straight turning .
chipenter:
Ran out of head room to drill and tap the spindle and mount , I will have to pitch a dormer in the roof to get the mill up to full height , just enugh room to spot for the screws , I have an old chuck without a backplate that works well for holding round things for drilling , I am thinking of useing a O ring to drive it got to work out the pullys next .
awemawson:
Whip the chuck off the drill, and use an MT shank drill to reduce headroom. If you don't have a suitable drill, pop a hole in an MT blank of drill size, with an axial locking screw.
