You must have access to a lathe---either wood or metal---And a friend that
understands them. He should understand this procedure.
1. Center your backing plate both horizontal and vertical, using a
dial gage, to the chuck of the lathe.
2. Make a cup, that fits on your "live center" in the tail stock.
(you can see since the live center is exactly in the center of
the chuck, then whatever is in between the two will be centered.)
3. Place the spinner tip in the cup and move spinner into the backing
plate. Rotate by hand. Don't turn the lathe on. (you don't use the lathe for
anything other than a device to hold and center the spinner to the plate.)
4. When centered, mark and drill your holes------you are done----and
I might suggest that this procedure be done prior to making the cutouts
for the prop.
