Go to any one of their pages under the "Punching" heading. Scroll
to the bottom of the page. There is a picture and sizes of the
punches that fit each particular punch. The very first page I
sent you told how to calculate the number of tons you would need
to accomplish your task.

Put your mouse on the word PUNCHING in the black band under their
logo. Go to any one of their punches listed. Scroll to the
bottom of that page to see available punches and sizes.

Put your mouse on the words PUNCHES & DIES in the black band. Go
to the "determining tonnages" page.

Thanks. I e-mailed Roper Whitney in hopes of finding the
smallest tool
I'll need to get done what I want. I just can't seem to find out
if
they have square die/punches on their site.

punching, they would not do it for you if you wanted them to.
I'm
sorry if I worded my first post poorly, I thought it was quite
clear that they manufacture tools. If you are close to the
edge,
you can probably get by with their lightest weight tools.

You have not said how far from an edge you are needing the

These folks are among the best at punching holes:
http://roperwhitney.com/tech/tech2.cfm

look at their choices under punching. The cost goes up with
thickness, size of hole, and distance from edge.

Nothing can be outsourced, and I'd need the tools and
know-how
for
future projects anyway.

These particular squared holes will be about 1/8" from the
edges(corners) of the stainless steel.

The square holes are necessary because I'm creating a hinge
set-up
where I'll need put squared Delrin bushings with round holes
through
them into the square holes created in the 1/16" thick
stainless
steel.
The holes need to be square so that only the rod that will go
through
the bushing will turn and not the bushing itself.

BTW. Can anyone tell me if there were logistical reasons why
square
hole bits were not made for a tool like the Rotabroach?

Thanks a lot.
