I went into my machine shop supply store and told Tim "We're going to be
RICH! I explained my idea of a cutting fluid that was like shaving cream
and would stick to the work. He walked over to a shelf and handed me a can
of foaming cutting fluid and said "Like this?".
Agreed. Even if it's bathroom reading material, there are a lot of things
in there that will surprise you as to being available, being available from
one source and being either too cheap ot expensive to ignore.
Oshkosh and the EAA clued me in on Clecos. Nice stuff when playing with sheet

government officials but my life isn't worth protecting at home
in their eyes." Dick Anthony Heller
Clecos come in all shapes too. Some have a wingnut on the end to pull
heavier parts together, some have jaws that clamp the sheets from the
edge. I have a toolbox full of them put away somewhere with all my
other sheetmetal tools. The basic clecos were very inexpensive when I
bought them US tool was one of the sellers.
I was a little late to the question, but I was thinking about a couple of
disks actuating micro switches or perhaps you could make two plastic disks
that you could sandwich a piece of paper you print out on your computer and
use optical sensors to actuate on two tracks of the disk.
The latter method could be real easy to make timing changes just by swapping
out the paper disk, and would suffer no mechanical wear like a roller cam.
If you are not part of the solution, you are not dissolved in the solvent.
Actually I have never visited your shop, but if I was going to be in the
neighborhood I would love the fifty cent tour.
I suspect that keeping an optical encoder setup free of crud would not be
too tough, but what ever way you build something so long as it works that is
the important thing.

Optical would be ideal, except that the lady in question has never won
the Lesbian Good Housekeeping Seal. I imagine that technology wouldn't
work for me, either. I know the shop floor is white, but I haven't
actually seen any of it in ages.

Proximity sensors seem to do a lot better job than microswitches since
there are no moving parts to wear. Optical switchs are a little more
problem since they have to be clean to operate properly.
