As shown elsewhere, I bought a cup grinding wheel. It needs an arbor.
I have a length of 12L14 that I will be using to make said arbor. It goes into a 20mm (.787") hole in the wheel. As the stock is only 1" diameter, this doesn't leave much in the way of a flange to support the wheel. I plan on adding large (~2") washers either side of the wheel to help support it and distribute the forces more evenly. My problem stems from the fact that I don't seem to have any suitable steel available.
My question is, will aluminum (.13" thick) be strong enough to support the wheel, of do I need to get some steel? Note that this wheel is to be used on the mini mill, so maximum speeds will be well under 1100rpm.

Full of ideas, but slow to produce parts
