Turn the pulleys
Turn the pulleys
Build up four solid wood pulleys 10 in across with 8 in faces and turn them in the lathe with a very slight crown; too much crown harms the belt.

Mount the pulleys
Mount the pulleys
Mount one pulley on a firmly held arbor in the lathe and the other three on iron-pipe shafts on a frame (drawing). Turn and file a true journal on each pipe, pour babbitt bushings in the pulleys, and cut oil grooves in the pipe or babbitt. Supporting the shafts on one side lets the belt slip off; supporting both sides is stronger.

Set up and run
Run the belt at about 2,500 ft per minute using the lathe's cone pulley. Set the work about 1 in below the belt on a table or a low sliding platform (two sets of tongue-and-groove joints at right angles), start the machine and press the belt down with a float like a blackboard eraser, or a roller.
