Bead roller advice needed.

[Frank's Trailer Works]

I talked to a duct guy today who thought it was done on a machine that uses a series of rollers to make the smooth roll over.

[Aerowood]

Yes, I can believe that. It's called roll forming, where the metal is rolled through a progressive series of dies with each one rolling the edge over a bit more then the last

[Aerowood]

How many pieces so you need to make?

[HiHoAgRV]

One option is to trace the edge onto a piece of plank, router a radius and work the blank down over the wood with a mallet a bit at a time.

I've done this to make ribs

[Aerowood]

That was my next suggestion

I am sorry if I high jacked this thread. It does have a very happy ending.

Here is the magical die. I wonder if Submariner got a similar die made. The fellow who made mine said he did a similar die about two years ago. I too prefer to own my own tooling.

[Aerowood]

Great. Do you have a Pexto bead roller

[Frank's Trailer Works]

I own a Harbor Freight roller. My friend Tom @Metal Benders has an electric drive Mittler bead roller.

Never used a REALLY nice powered one before
