I understand about heat shrinking and flame straightening and the principles behind it from before. So I was interested to learn of the existence of shrinking discs and how they work via friction, they also don't seem to require the metal to get red hot from what I've been able to observe from their usage.
One thing I have observed however is they are all used on big grinders and the smallest wheel is around 125mm and they are used on panels that are removed from the car and being prepped for repainting.
But hasn't anyone had the idea to make even smaller shrinking wheels like 50mm or even smaller? Like mounting such a disc on an air driven tool that can go up to 15-20k rpms, or even smaller for the tiny grinders on flexible cables.
My idea is that such a small tool could be gotten in behind a panel such as on a door and be used to shrink the panel from behind so you don't have to disassemble the door and remove the door skin. And if you can shrink it from behind it seems it could be useful for paintless dent repairs too, assuming the heat from a shrinking disc isn't so high that it would damage the paint even when applied from behind the panel. That's one thing I am unsure about.
