What diameter is the back of the spinner? How many holes?

I measured a few others and they seem to be between 50 and 65
thousands thick, I am going to try spinning it on a lathe and forming
it that way but am not sure what alloy to use, I think 2024 but if
anybody knows it would be appreciated. I have searched on the net and
found nothing under propellor spinner. Does it have to be heat treated
after forming or is it better left soft.
I have a front plate which I will be matching to the spinner,,,,I know
it would probably be more advisable to just buy one but I like to try
new things and spin forming a new back plate sounds interesting.

It really depends on the spinner and prop in question. Some backing
plates are of complex shape and usually are .065" or more thickness.

The frontplate is just as important as the backplate, too.
