Anyone tried using the Friction System made by Sunchaser tools? I saw a guy using it at a Goodguys show and it seemed pretty interesting. I sure would like to avoid turning my truck into a bondo bucket (my hammering skills aren't really up to par).
This is a slick system. It can be used on any grinder (almost). It involves a disk, usually metal, atached to your grinder. You need a grinder that will allow you to control the RPM's. The tool is used in heat shrinking/expansion. The purpose of the spinning metal disk is to generate heat. Heat causes the metal to expand. Its used on large flat panels such as hoods or roofs. I saw it used on a roof chop operation. There were a few low spots in the roof after welding. The low spots were 3'x3'. The disc is used like a polisher. By moving the disc around on the sheet metal you can expanding the metal and bingo no low spot, or at least no filler only blocking primer surfacer. You need to really bond with this machine because it can do a lot of damage. You have to know when to back off and when to stay on.
Hey Craig, if you're still inerested, the Sunchaser tool works. I have one. Unfortunately, you will have to be good with the hammer and dolly for it to work. You must get the dent back to close to normal, just a bit high. Then you hit it with the shrink disc, then hit it with a cool wet rag. Only the high points get heated and then shrunk. It takes a lot of practice, but it works! John in Sacramento
Would it be possible to use a plastic sanding disc without any paper on it to heat up high spots? Could you make something like this with a scrap piece of <a href="http://motorhaven.autoanything.com/">sheet metal</a> that's nice and smooth?
I just hate spending a small fortune on specialty tools.
I talked with a body guy in Reno who was buying just the shrink disk, not the rest of the kit. He said that he had used a homemade tool that was a rubber buff pad with metal arber in his high speed drill. He mounted old pieces of sand paper smooth side down and rubbed on the metal that way to acheive the heat on the high places. He said it took a lot of work to keep putting on more sand paper all the time, so he was just buying the disk. The shrink disk does work and the only way to justify the cost (250.00 for the kit) is to balance it against the cost of having a body guy work on you fender (70/hr.) Also, they offer a legitimate 30-day money-back gaurantee if you are not satisfied. Good luck, John
