Brief Description: Getting the idler sproket ready
Assemble pedal crank to see where the chain is going to run, i.e. how far from the tube.
Cut the worm gear off the sproket with abrasive wheel while spinning it in the lathe. That stuff is real hard.
Also cut the rear hub down using the same method.
Cut a square of .125" 4130 plate to weld to the back of the cutoff hub then put a 3/8" dia hole in the middle so I could turn it on the lathe. Used a bolt and nut to hold the piece.
