David A. Posted November 17, 2016 Report Share Posted November 17, 2016 I'm currently working the dents out of my 1950 B2B bed side panels. From all the years of the fenders pulling on the panels, it has caused the sides to bow out. Does anyone know how to go about shrinking the metal back down so the sides are straight? If I try to push in on the sides to make them straight, it just pops in and bows toward the inside. Any help would be appreciated! Quote Link to comment Share on other sites More sharing options...
Dennis46PU Posted November 17, 2016 Report Share Posted November 17, 2016 I have seen one of these work. Time consuming and patience. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR1.TRC0.A0.H0.Xshrinking+disc.TRS0&_nkw=shrinking+disc&_sacat=0 Quote Link to comment Share on other sites More sharing options...
PT81Jan Posted November 17, 2016 Report Share Posted November 17, 2016 Difficult to give an advice without seeing the bow outs. Might be that you will be able to straighten it by cold forming. If not, heating the bowed area with a torch will help to get the required result. As last option it sometimes is necessary to do one or more cuts into the sheet metal, aling it and close the cuts by welding. If you had a picture, it might be easier to estimate what could be the right way. Quote Link to comment Share on other sites More sharing options...
desoto1939 Posted November 17, 2016 Report Share Posted November 17, 2016 If you are not experienced in body and fender repair I would be very couscous with the shrinking disk. If you really want to have the perfect sides then I would take to a good body guy and have them work on them. I know my talents and that is not one of them so I would farm it out, but maybe you have done prior body and dent work and feel comfortable doing this type of work. If you do too much damage then it will cost you even more to fix what you have done, get an estimate from a professional to see what the cost would be. Someone might do it in their slow time on a straight hourly rate. Rich Hartung desoto1939@aol.com Quote Link to comment Share on other sites More sharing options...
David A. Posted November 17, 2016 Author Report Share Posted November 17, 2016 Here are a couple pictures of the sides. The bow doesn't show up very well in the pictures. I've done a fair amount of body work in the past, but never had to shrink any metal over this large of an area. As Rich said above, I don't want to make things any worse.

Dennis46PU Posted November 17, 2016 Report Share Posted November 17, 2016 Shrinking has always been more difficult than stretching for me. I never have been fond of a torch method as it is uneven and too hot in areas you don't want it. It might be best to let a professional do it in the long run.

PT81Jan Posted November 17, 2016 Report Share Posted November 17, 2016 I agree, shrinking sheet metal is much more demanding. And when I see the pictures I am sure that the oblong groove needs to be shrinked. Thank you for the pics! Quote Link to comment Share on other sites More sharing options...
David A. Posted November 18, 2016 Author Report Share Posted November 18, 2016 Thank you for the replies. I will probably follow the advice and seek someone who is experienced in this sort of thing. I'd sure hate to make things worse. Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted November 18, 2016 Report Share Posted November 18, 2016 So if you decide to get a price quote for repair of the sides , you can compare that price to the cost of new replacement bed sides . Quote Link to comment Share on other sites More sharing options...
The Oil Soup Posted November 18, 2016 Report Share Posted November 18, 2016 I would remove the osb, perhaps that is distorting the side panels. Quote Link to comment Share on other sites More sharing options...
Dave72dt Posted November 19, 2016 Report Share Posted November 19, 2016 I've done three sets of them, the easiest was with an oxy-acetylene torch and all required lots of time and patience. I currently use a stud gun. I've found propane bottle torches don't work well and suspect a shrinking disc would not work well on these bed sides as well. I don't have a shrinking disc and have never used one so I could be all wrong on them. I personally think they may have been bowed from the factory, especially if it's a high side box due to the stress and stretch from the pressing the embossed pattern. 1 Quote Link to comment Share on other sites More sharing options...

I have looked for new bed sides, but haven't been able to find the high sides. Are the high side bed sides available? If so who do I need to contact? thanks!

The osb is just part of a roll around table I made to support the bed while I'm working on it. Quote Link to comment Share on other sites More sharing options...
The Oil Soup Posted November 19, 2016 Report Share Posted November 19, 2016 So from the pics it look like the sides only bow out at the bottom edge. Do you have the four pieces of c channel that span the width of the bed? They should stabilize that lower edge. Quote Link to comment Share on other sites More sharing options...
David A. Posted November 19, 2016 Author Report Share Posted November 19, 2016 The pictures don't show the problem very well. The bottom is pretty straight. The bow is in the middle probably from where the fenders constantly pulled on them. The side that is bowed in is only in because I pushed it in. It normally is bowed out but since its stretched, it pops in when i try to push it straight. Quote Link to comment Share on other sites More sharing options...
JBNeal Posted November 19, 2016 Report Share Posted November 19, 2016 I worked at an OEM that would occasionally run into minor issues that people might think we're indicative of a larger problem, to which our VP of sales would boast to customers that the issue was in fact a new equipment feature Quote Link to comment Share on other sites More sharing options...
48Dodger Posted November 23, 2016 Report Share Posted November 23, 2016 getting it close...... Never tried to get it perfect, but it was much better for the effort. Lowside beds are easier to replace the steel on, no embossment. 48D Quote Link to comment Share on other sites More sharing options...
52b3b Joe Posted November 28, 2016 Report Share Posted November 28, 2016 (edited) My sides were bowed in 3/4 of an inch from the fenders being hit. I spent tons of time working on them to get them better. I even took them to a local shop to have them done, which didn't result good. They did get some of the work done, but I ended up finishing them. I had the best luck with using a torch to shrink the metal. I got to a point where no matter what I did, I couldn't get the metal to do much more, and I kept chasing "waves" or ripples on the sides trying to get it perfect. I even tried jumping on the sides while on saw horses to move it at one point. I finally took a hammer and dolly and worked the displaced areas to the center again, and hit them with light heat to relax the metal once I had it where I wanted it (you could pop it in and out). Once I was happy enough (or frustrated enough...depends on how you want to look at it!) I used duraglass and filled what I couldn't get out. I know it sounds bad, but I have probably in THE worst area 3/16" of filler. I was able to get the sides pretty straight considering where I started. I haven't had any issues with the bed since I finished it almost 1.5 years ago, and Its had pretty heavy loads in the bed, and even people sitting on the sides going in and out of rough fields.
