Please help, I can not figure a way to weld the flanges in my offset smoker doors with out the corners being sprung out. Not sure if it is when in cutting the doors out or welding the flanges on. I will take any advise anyone has. How can fix the doors now that the corners have sprung out. I'm looking for the tightest fit possible. 1/4 in hot rolled steel pipe, hypotherm plasma, hobart 140 mig, oxy/acetylene torch, are the tools I have plus anything I can buy to fix this problem.
Reply:Consult the sketches posted in thread # 5 of 13 of http://www.smokingmeatforums.com/t/5...r-smoker-doors.The diagrams will show you how to layout the main chamber opening and explain the cut/weld sequence for proper fitup & distortion control. Not a smoker pro fabricator, but currently preparing a design/build.Many welders here have fabricated some impressive smokers. They should be able to get you back on track and recover from your sprung geometry. Also, be sure to access the smoker build thread on the forum for additional insight.Best fortune with your smoker build.Last edited by ManoKai; 08-20-2014 at 05:19 AM."Discovery is to see what everybody else has seen, and to think what nobody else has thought" - Albert Szent-Gyorgyi

Reply:amusick, when you ran the diagonal beads to take out the warp, did you grind them flat afterwards? Or would that bring the warping back? I would suppose that if you did grind them, you would not let grinding heat build up and complicate things.
Reply:I did grind them flat.The welds themselves are not what brings it back into shape, just the heat . I did the welds on the back so the heat would draw the door back closed. Same thing you notice when you weld a tab on something, it always wants to go toward the heat.I started with the door closed and marked a line from where it came out of line on each plane, opened the door and connected the dots as a guide for the weld. Each time it got closer and that's why they are spaced the way they are. I don't know if letting them sit overnight was necessary or not but I definitely did not want to screw it up more during my "fix".Didn't worry about grinding heat when I knocked the welds off, I had my Ironman 230 pegged when I ran those welds and it still took a few so I knew the grinder wouldn't introduce near that amount of heat.Sorry if that's a lousy explanation brother, I'm not exactly a wordsmith.
Reply:Put the flange on the door opening, not the door itself.

Reply:Just use a big, semi flat faced hammer and smack them back into compliance after the fact.
Reply:If you have a TIG you can use it to pull the door back in shape. Don't have to use filler so there is nothing to grind off afterwards.You are just heating it and letting it cool and it will shrink toward the side you heated. Could be done with an O/A or O/P torch as well.GravelThe difference between theory and practice is that in theory there is no difference.
Reply:amusick,Your explanation of grinding out the welds was very clear. Thanks for the info...for future reference when I warp something.. |
