Used my scroll saw to cut out the Prop hub spinner plate.. There are two plates, the main plate and the stiffner plate. The stiffner plate already has a cut out for the hub so what you do is place this on the hub with the bolts then trim to make sure nothing hits the hub all the way around. Then match up with the spinner plate, trace a line for the cut out. Then comes the cutting on the scroll saw.
Cut on the scroll saw. Went through many blades.
There is a spacer and washer on each of the 4 bolts.
