Basically, how to? Rolled wire edges on thin aluminum sheet?

On the right side of the page are illustrations on how to do it on a
rotary machine.

You can also do it with a hammer and a stake, but that takes a long
explanation.

If the sheet is flat you could cut an acceptably half round edge on a piece
of steel, clamp it to the aluminum and bend the seam allowance over it. Then
insert the wire and hammer or press the seam closed.

The 3-in-1 import sheet metal machine has grooves in the rolls for making
circular wire loops and possibly rolled wired edges. The CM manual doesn't
tell how. It didn't work out for me because I couldn't simultaneously hold
the metal and wire in place and turn the handle.

The latter sounds more like what I need.
It's not a flat piece though.

It a cockpit combing (surround/fairing) piece that needs a stiffened edge.

Sounds like a job for four hands?
