I once had to make some thin parts for some medical device. These were
printed using the Metalphoto process and needed to be accurate to about
plus or minus 5 thou. They also had adhesive on the back with a paper
liner.
So what I did was....
punch a center hole in them with a Roper whitney hand operated punch
press...
then I stacked them all together on a mandrel, Very fresh HSS cutter
chucked them up in my 6 inch Atlas lathe and turned them to final
outside diameter.
Everyone was happy
what more can you ask for?
