Posted May 22, 200915 yr A short while ago I read about repairing dented header pipes by filling with water and freezing it. Well, it works pretty well. Here are before and after pics: Before... After... Looks pretty good... Just out of the freezer... Thawing out... Duke, the guy running the show...
May 31, 200915 yr Nice one, iv never seen a before and after pic on the freezing technique, done a good job there. Cool dog by the way
May 31, 200915 yr Moderator Wow...Thats fantastic, wonder if it will work on a dented fuel tank. So what did you do, bung one end up and fill with water? Down Duke...DOWN...
May 31, 200915 yr used to use this technique when i had Nitro Cars, quite often my beloved monster truck would end up flying off into a tree and leaving a nice dent in my shiny tuned pipe. not sure how it would work with fuel tanks because of the contours and seams, may do more damage than good
June 2, 200915 yr Author You guys are too funny! Duke is three years old and pretty much runs the neighborhood. The electrical wiring goes directly into my fusebox and powers the house every time he barks which is a lot! As far as the pipe goes I didn't block the ends or anything like that. I just filled the two middle pipes with water and stuck it in the freezer. That's it. Maybe there is some one who can explain why when freezing the expansion which pushes out the dent doesn't just expand towards the open ends of the pipe! I thought about that myself but decided to just try it out. There are some smart guys out there so how about an explanation...
June 2, 200915 yr Author very good, I'll stick it in workshop drewps Hey Drew, I'm new on the site. I saw you moved the header post over to the workshop. Should my FZ 750 rebuild be posted there rather than in the gallery? I'm fine with moving it there if that's where it should be. Thanks, Kevin

June 6, 200915 yr Author the reson is because the exposed ends freez first then it freezes towards the middle and when there isent any where to go it expands in any way it can and obviously the dent gets pushed back out Why didn't I think of that? Thanks for the info, so now we know!
August 11, 201014 yr Hello! you did a fantastic job.How did you do it.Please tell me. dog is so sweeetttttttttttt.
August 12, 201014 yr Wow...Thats fantastic, wonder if it will work on a dented fuel tank. So what did you do, bung one end up and fill with water? Down Duke...DOWN... I have heard from a few folks that letting your dented tank sit in the sun (or use blowdryer on it or apply some heat with fire? and alum foil protecting tank paint... option #1 best hehe)... Then with heavy duty gloves suitable for dry ice... to take some dry ice and apply it to the dent... Hold it down for a lil' and it'll pop out as long as dent isn't a 'hard dent' (has hard creases): http://www.ehow.com/how_6620077_remove-dent-motorcycle-gas-tank.html http://www.videojug.com/film/dent-removal-technique btw nice technique, ill have to remember that in case ever need.
