[AT] Pitman rivets?

Those heading plates have multiple uses -- for heading (as you
describe), for shearing to proper length (with a punch in the exit
hole), and for cutting rivet holes in sheet metal that is to be riveted.


I'm learning a whole lot more about riveting than I ever expected to
with this project.  And all this is just so I can restore an old MD-6
mower without having to do all that riveting with a ball-peen hammer.  I
found out that the brute-force method of riveting takes 16 tons of
pressure for this size of rivet.  That's a bit more than I can get on my
12-ton press.  :-)  Maybe I should go down to "The Tool Box" and look
over their 30-ton press a little more carefully.

I'll assume he has a heading plate then. If not it is nothing special,
just a hunk of steel at least as thick as the rivet material, with a
hole the same size as the rivet material and secured in a vice or on an
anvil. Without a plate the end of the steel will upset enough that it
will not fit. Make sure it is NOT a blind hole though.
