The McMaster-Carr bag 'O springs showed up.
Now to replace the shabby rusty Home Depot springs with the real deal.

I got 8 springs and three pairs of fins to stick them to.

Just bent the end loop around the posts added nylon line down the middle and race bike innertube and I was done in 20 min. No intermediate mechanism.
Cost: around 11 bux.

Next the wife's biofins.
A bigger post. Here I pierced the post with stainless cotter pins. Not permanent as cotter pins are easy to remove.
Cost: around 12 bux

My old neon yello biofins (shush, I have paid for them with enough DIR scoffs)
I thought that I would steal ideas from Chuck Tribolet.
Here I dissected the strap buckle only to find that the clasp has the perfect mechanism for holding the end of spring loop. 5 minutes a pair. The end result is a spring strap WITH a quick release buckle.
Cost: around 11 bux.

Next I am going to whittle a whole tank out of a billet of steel with a nail file...
