Is there anything to know besides sticking the pipe through the
spring and bending it?

Thanks.

Are you talking about ductile copper? If so, that's all there is to it.

Make sure that the pipe goes in the correct end of the spring. It has to
wind CCW from the top. If you get it wrong just turn the spring around.

Less than 1 inch diameter 6061 or "structural" aluminum from
McMaster-Carr. Seemed to work okay, I just wanted to avoid
crimping or weakening the pipe. It is shaped like the upper rear part
of a folding chair, an upside down U.

Are you sure I don't need a left-handed monkey wrench to take it apart
if I get it wrong?

I think you can fix that with a can of vacuum, too, but I can't remember
the details.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.

I can't seem to locate an MSDS for vacuum.

We laugh at "can of vacuum" but if you look under the hood of '76
Lincoln you'll find a coffee can being used as a vacuum
reservoir--maintains a pressure low enough to work the headlight covers
several times.

Well, that sucks.

Does not! All that stuff outside the can blows!

He's just havinga bit of fun. You've got to unwind the spring and wind
it the other way around. ;-)

Yeah, but you have to have a Langstrom 7 inch wrench to do that. Contrary
to popular belief it works on Finley sprinkler heads too.
