Kim, not sure what you are using it for but a lot of pop up laundry bins and car sun shades have that sort of metal.

Spring steel?

Thanks, guys! Lots to look through…

Jason, if I told you, I’d have to kill you! heeheehee :D

Kim, from what you described it looks as if you’re looking to connect two lever type parts at a pivot point. For something like that you might want to consider torsion springs.

Good point williamj!

The Wikipedia page has a good example of inline torsion.

William, thanks for the examples. This will need to have a fairly flat profile, so a spring wouldn’t work if laid sideways. I have thought of a spring stood on it’s end, but then it would probably be thicker than needed. Any other ideas?
Jacob, there was way too much math in your link! I can’t follow that kind of thing, but thanks for whatever that was. lol

Kim, the only problem with a "(it may be folded over into a U, but a very thin, compact U)* is that the would be very little spring travel and the strength of the spring would be almost negligible. Will keep this in the back of my head and if I think of anything I’ll post it here. : /

Thanks William. I know, it’s a head scratcher…

Michael: No, it’s not! :)
I feel like I’m playing Charades!

Holy moly! I see some that may work!

I believe that there should be several rows of springs attached between two wooden boards for example, a fold-up chair where the springs are attached between two boards that support the back and buttocks. As for locking the back board in place without being loose, might need 2 side handles to lock the two boards at a right angle shape

Kim, are you building a head scratcher that is smaller than a bread box? lol

ARTHUR PEAU, If you’re describing what I think you’re describing (an idea); don’t do it in the forums (It’s considered public disclosure; and makes the idea un-patentable).

Oh, and WELCOME TO THE FORUMS! : )

I think he was building a deck chair! lol Not sure what that was all about, but I appreciate the effort.

The closest thing I can come to with what I need would be the same technology as a bounceboard or springboard as used in gymnastics. Only really little. :)

Heat treated stainless steel is the perfect product for my MG better than spring steel I have never ever had a lift spring break

Take a look at the plastic pants hangers. There is a steel flexible clip on each side. 

That's a great idea, Jim.  I believe this is what you're talking about.
