The spindle handwheel was provided to make the task of controlling the spindle easier. With it you can quickly stop the spindle or turn it by hand to tap a thread or inspect a part.
The spindle handwheel is installed on the end of the headstock spindle shaft next to the drive pulley. There is a hole predrilled in the spindle shaft, and the cone point set screw in the handwheel should be aligned to index in the hole. If you cannot push the handwheel onto the shaft far enough to engage the hole, it may be because the pulley has been moved slightly on the shaft. If this is the case, loosen the set screw holding the pulley and move it closer to the headstock so that the handwheel set screw can align with the hole.
FIGURE 1-The point of the handwheel set screw should go into the hole in the spindle shaft. The pulley set screw is located in the smaller pulley groove in case the pulley needs to be moved toward the headstock case to allow the handwheel set screw to align with the small hole in the shaft.
Most Sherline steel parts are finished with a black oxide coating to prevent rust, however, a polished steel part has a better "feel". For this reason we left the steel on the handwheel unfinished. Using the handwheel will keep the outside diameter shiny. If you live in a humid climate, the handwheel can be polished using a Scotchbrite® pad or fine steel wool to remove any rust that may form. Since it rotates with the spindle, polishing it while it is rotating is an easy task. Before you store the machine, wipe on a light coating of rust preventative or light machine oil.
