I have seen an electrical induction system for removing dents from car bodywork. Does anyone know whether this system would work for removing dents from a steel frame? Other methods I tried (frame blocks, hammering from inside tube, etc) have required filling, but the induction system seems to remove dents completely without even damaging paint.
A tube is a bit different to a sheet isn't it, and I think a tube will typically take a much greater force to dent in the first place which may then mean it is more difficult to remove?
I think the success might depend on whether it is a "soft" dent (larger radius) or a hard dent (smaller radius)? Again, because more force is required to dent a tube than a sheet I think hard dents are more common.
It would be very interesting to see if it worked though, if someone with the kit was willign to give it a try.
Are we talking about spot welding a tab on and using a slide hammer to pull the dent out?
No, the system uses electrical induction. The frame isn't hit or manipulated in any way.
Here is a video of it in operation - https://www.youtube.com/watch?v=UQutSKiRf_o
As I said, I have tried other methods in the past and they always require filling.
I haven't found anyone near me with the equipment. When I do I'll take a frame round to see how effective it is.
@user83106 did you get anywhere with this ?
I'm guessing the process shrinks the metal, so works on a flat surface, but would put a flat in a round tube ..
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
