Delta Rockwell 10" table saw motor shaft extension with sliding pulley. Nice shape as shown. This was used on the 10" table saw / 6" jointer combo model which shared a single motor. The pulley slides on the shaft to either power the saw or the jointer. The ID of the shaft is 3/4" and it is 6 3/8" in length with a 3 1/2" OD pulley. U.S. shipping only. Thanks.
