Marj:
Just my $0.02 here, but I recently discovered the joy of using my
Peter Pugger for extruding. I use plywood templates of 1/2 inch
thick material. Plywood is easy to drill, cut and shape, and the
business surface of the die (the edges hitting the clay as it pushes
through) can be easily smoothed with a file and some sandpaper. I
don't bolt them on, though there are threaded holes in the end of
the pugger for that. Instead, I use a few (3 or 4) "C" clamps, and
just clamp the die on to the end flange. Yeah, it's "cheating", but
it's easy to change, and no monkeying around with a wrench when your
hands are covered in clay. AND (:>) I can scrounge up scrap plywood
at any building site...free is good!

Best Regards,
Wayne Seidl
