Can you use a bead roller to pre-stretch?
I'm experimenting with my reinforced Woodward fab bead roller. I read that I need to be pre-stretching bead areas to reduce warping.
I don't have an E-wheel but was wondering if you could pre-stretch with the bead roller? Does anyone make stretching dies for a bead roller? Mine isn't powered so I figured I could just take the big handle off and run the sheet through a few times like an e-wheel. Would this work?

Peter PS make sure that the pre stretch area is just a bit wider than the bead needed and..... always make a test piece before starting the new bead. Once ready to do the bead .....simply try to do it in a few passes not all at once,........ (depending on the dept?) I found that this way there is very little (if any '' warping'' )

Thanks Peter. That sounds like the same advice I was seeing on YouTube videos from Lazze and the like.
Does anyone make the dies already? I haven't been able to find any via Google search.
