Thanks but I don't have a problem drilling the backplate. My ZDZ came with a prop drill jig thats made up the exact same way. It has a 1 inch thick hub made of steel, and a 10mm bolt with nut and washers to connect to the prop or backplate.

Easy to drill by hand but I guess I am just being lazy. I figured if i had to order a new spinner to fit a menz prop, why not have it drilled as well.

Also i thought that the backplate didn't have the 10mm hole drilled in it yet and I know if you don't drill this straight you will throw off the balance.
