Can you run that through a pair of rollers to flatten it out? It
could even start the curve for the coil you want to make.
I guess I could find a roller. The sheared edge was also rough. We'd
have to dress it after flattening.
And we do not want it pre-curved. The purpose here is to keep it under
tension so that when it un-winds a little (about one turn on a 2.5" hub),
it stays flat-wound and self-supporting.
It's for a grounding strap on a rotary table. The table can only rotate
355 degrees, but house rules don't allow "wiper" type ground bonds in
this kind of environment. 'Has to be metal-to-metal and bonded with a
bolt.
The length of 80" was selected (stock sizes, so you picks what they
carries) because that allows the strip to unwind a minimal amount in
diameter with an approximately 10" length change.
You can't use a flat, tinned copper braid for a ground strap?

I tin the ends and drill a hole through the now solid area. I use RMA
flux, and clean it well but you can also crimp a lug on each end.
