Rotor spacers

Bought a 6061 aluminium drop from Ebay approximately 7" diameter and 2.7 thick to make rotor spacers out of. It was band sawed on both ends and was turned with two eccentric diameters. Nothing was square. It was $27 shipped so a great price. The plan was to chuck it as best as possible, bore and face one end and then have something to base the rest on.
