John, wouldn't a tube cause more problems, if it's length is not super precise?

I have been talking about collapsible tubes as used extensively in some applications.

Because your tubes would be relatively long a pair of thin wall aluminum tubes would compress the amount needed, a bit of trialing to get the right combination of force/distance needed, perhaps a bit OTT for you.
