I have used three of Jack's tool...they work fast and wear slow!  Great for
making binoc' scopes...the tool won't change radius...also great if you make
batches of mirrors since you get such long mileage from one aluminum tool.

I'm surprised they aren't mentioned more, especially for those using
grinding machines, turning out stacks of mirrors.  ;-)
