1.5" brass sink tail piece found at any home store.  It's thin brass 
just sharpen it up with some fine sandpaper and start using it like a 
cookie cutter to cut out foam disks.  Keep a UHMW cutting board under 
your work so ya dont mess up yer work surface or dull yer cutter too 
quickly.  When the cutter does dull a few twists with the sandpaper and 
you are sharp and ready to go again.

I typically punch out 6 or so foam disks and they just stack up inside 
the tail piece.  The I have a shaft with a UHMW core and I just sure it 
as a plunger to push the disks out of the tail piece into a box and then 
keep cutting.
