Been working on worn splines on the PTO shaft off of a Bolens 1050. The shaft is 3/4" diameter and uses a 6 tooth spline to attach the slip joint onto it as well as where the drive pulley mounts. The splines were worn where the pulley mounts so I welded the worn areas of the spline back up and turned them back down to the correct O.D. I decided I would try and make a slotting tool to remove the metal in the groove area. The idea will be to mount the shaft in the lathe and use the lathe chuck to index the shaft and the slotter will be mounted to the cross slide and hold a tool bit shaped to the correct profile and scrape the metal out of the grooved area by pushing the tool bit in a horizontal motion towards the head of the lathe parallel to the PTO shaft. I had a worn out 30 tooth gear with a keyed 3/4" shaft "X" hub welded to the gear. I ground the weld off and removed the hub from the gear which I am hoping will serve as an inexpensive barrel for the slotter shaft. The hub was stepped so I turned the step down in the lathe and then mounted the hub on the PTO shaft and locked it there with the set screws to finish turning the outside of the hub.
