Plymouthy Adams Posted December 30, 2009 Report Posted December 30, 2009 (edited) shrinking disc actually...been out playing a bit with a P15 rear fender...the more I use that disc the better I like it..still not acheived perfection, don't even expect to..but do pretty good with it...these things amaze me at their simplicity and abiltiy to work out creases and dents...I believe this panel could be worked now with just a few coats of primer surfacer..well..maybe not but sure feel super smooth at this point compared to what it started out as... anyway...weather is fair and I felt like piddling at something..

Joe Flanagan Posted December 30, 2009 Report Posted December 30, 2009 Tim, I too was amazed at how they work. I didn't use a real shrinking disc but the back of a sanding disc installed on my grinder backwards. I did get into a few situations where the shrinking disc either had no effect or made things worse and I chalk this up to my not knowing where to work the metal and not understanding how it distorts. But there were a few dings that I hammered out with a hammer and dolly and then tweaked with the disc and they came out really well. Do you have pictures? Quote
Plymouthy Adams Posted December 30, 2009 Author Report Posted December 30, 2009 the before picture I just slooked at in my camera preview..does not show the damage..the flash washed out the damaged area for the most part..I have not photographed the end result after the shrinking disc.. now to rub it in...wife made an excellent bowl of vegetable beef soup (slow cooking since last evening) and a pan of good cornbread..with a couple splashes of Tabasco sauce...a bit of cold milk for the washdown..yah..too much...but it hit the spot for a cold day..yes the temp is dropping fast this evening...

greg g Posted December 30, 2009 Report Posted December 30, 2009 Camera tip. When shooting bare metal, I have found that covering the the flash partially helps washing out things. I had a piece of the opaque adhesive tape over the flash on my old camera. On the new one I just cover it half way with my finger. If it comes out a bit dark, you can always do an auto adjust when you up load the pic to your computer. Quote

Frank Blackstone Posted December 31, 2009 Report Posted December 31, 2009 Tim I got the same results with a torch and wet rag on my roof that had been oil caned. Basic physics I guess but almost magical. Better than beating as I have done before. Quote
Joe Flanagan Posted December 31, 2009 Report Posted December 31, 2009 Frank, I tried that too. Watched a bunch of videos on YouTube first. It worked well until I got to the point where I really needed to localize the heat. Quote
Plymouthy Adams Posted December 31, 2009 Author Report Posted December 31, 2009 Frank...I have used the torch method in the past also, but it cannot do what the shrinking disc does..the disc main advantage is the localized heat that is imparted to the high spot where the torch gets the entire surounding area. The rotation of the disc along with the weight/pressure will bring these high spot down super quick with less chance of distorting a large area..as the disc hits these high spots it acts as a hammer itself and pushes the metal in the right direction to seek correct level. If you have access to both sides of the panel..you can alternate front and back and be done before you know it..most dents can be removed without the dolly and hammer this way..a removable fender is an ideal candiate for this process..the fender section I worked earlier yesterday was a phrenologists dream. The bumps where it had been worked by a PO were a nasty lot covering the curved section just below and rearward of the fuel fill hole to the body seam..I used the hammer only in the vicinity of the 90 degree bend in the mounting flange of the fender. The disc I have is a very heavy model compared to the one in the instructional video pasted above by dezeldoc.. To use one will make a believer out of panel beaters in my opinion..but each person has their own methods of doing work..On a whim I bought the disc...tried it, am sold... Quote
dezeldoc Posted December 31, 2009 Report Posted December 31, 2009 The only thing i don't like about mine is it has a 3/16 edge hanging over and it gets real close to the ol fingers! but man does it work great. Quote
Joe Flanagan Posted December 31, 2009 Report Posted December 31, 2009 Boy this past summer I sure wish I'd been closer to you more experienced guys while I was beating my head against the wall with body work. That was a tough learning curve and I'm not sure I learned everything I was supposed to. Quote
dezeldoc Posted January 1, 2010 Report Posted January 1, 2010 Takes a lot of years and time on repairs to learn, hell after 30yrs i am still learning. if you want some good practice try some license plates with no filler! nice thin metal and all the raised and contoured parts will make ya real good! here are a few pics of the last plate i did this week. That thing was wadded up under a trailer and warped and flattened out good. Quote
Rollie��� Posted January 1, 2010 Report Posted January 1, 2010 what the heck Dezeldoc?!?! Can you work that magic on some stainless trim? Quote
