Fab tech 3: How to determine bead rolling pre-stretch

Great video. I talk about this on my channel quite a bit. I’m doing an aluminum radiator cover right now. Used a similar technique as yours. My English wheel is on sick leave right now waiting for me to install me upper wheel and lower anvils. I used my planishing hammer in the radiator example. English wheel is better though for smooth Pre stretch. Thanks for sharing!)

The bead roller does not perfectly bend the metal at an angle. It works slightly like an English wheel. You expected that by having the same length afterwards the panel would not have it's crown altered. The panels crown was altered. If you don't want to trim the edge of the panel, this idea works perfectly.

Hey, thank you for making and sharing this video. I have just bought a bead roller for a replica MG I am building. I need to roll a recess all around 5 or 6 bespoke panels I am making so I really don't want to mess things up with distortion. I am guessing that the same rule applies to a straight bead as well as a framed recess as formed with a Bead Roller? 🤔 Kind regards Paul from 48 Spokes 🇬🇧

[@TheHotRodWorkshop]

Correct, any form in the 3rd dimension of a flat panel will require stretch to keep from effecting the surrounding areas. I recommend a couple trial runs on a scrap piece of same thickness to dial in the correct amount of stretch required for the amount of step you want in the panel. Good luck on your project and thank you for watching!
