Dent removal

I have a nice sized dent on my tank,i would like to get it it removed before getting tank repainted.I heard you could weld a screw on it then pull it out the dent,then grind screw off.I am thinking of trying this myself after i drain the tank.But have never welded and wonder if vapor from the tank would be a problem.Any ideas?Thanks

 

If you have never welded then I would say it's a bad idea to start on a project of this type. The tank is really thin and you will more than likely burn several holes in your tank.
They do have special spot welders for just that sort of thing, that will weld small pins which can be pulled with a slide hammer. I would recommend that you let a body shop do this. then you can do the painting.
Good luck.

 

Ive seen this technique applied in the automotive repair shops. Honestly, though I havent seen it done on a bike tank. Sometimes it doesnt take the dent out totally, depending on the type of dent. At the bare minimum you should be able to pull out the dent enough to patch with a little bit of micro lite bondo or something. I would recomend rinsing inside your tank with water and air hose dry before you do this. Also, you may want to make sure when you do weld this screw onto your tank, that your not welding so hot that the screw burns through the thin metal of the tank. If you have never welded than I would have someone who has do the job for you. Any how, Good Luck! and let us know how it comes out

 

I cut my tank in half to knock out a difficult dent and the rewelding process was tricky. As stated, the metal is thin and it's easy to blow a hole in it even though we used a TIG welder.

There was a thread with a link around somewhere showing a guy that just used a piece of timber and a hot glue gun to glue it on. A quick tug and out it comes(apparently).

Depends on dent size and location.

 

Hot Glue gun and that bolt with a aluminum bridge ... There is this tool called a ding king ... works OK. paintless dent removal is another option ... albeit pricy ...
Cool.

Check and see if anyone does paintless dent repair in your area. They use a bunch of different sized rods and massage the dent out from the inside. If there is factory paint (on cars anyways) then you will not need to repaint. Might be worth checking out.

 

Do the welding-on trick ... but, do it right! Most well-stocked "Rent-All" stores have the tool for the job. Every good auto-body shop has one! It's a dent-pulling set-up that's EASY to use and EVERYTHING is right in the kit.
It's a spot-welding gun that welds copper "rivit-rods" right on the dent. You load a rivit ... put the gun on the tank where you want the rivit welded-on ... and, -- just pull the trigger. The rivit stays welded on the metal and you load-up another one and continue welding-on the rivits until you have the area to be pulled-out sufficiently covered. Then, you put the gun away and switch to the puller. The puller grips the welded-on rivit and lets you pull-out the area -- without having to risk damage to the tank from too much heat from a MiG or brazing-on. Just remember to pull-out the dent from the OUTSIDE perimeter working toward the middle. When you have the dent pulled-out ... all you need to do is snip-off the rivits and grind off the small head spotted to the tank. Makes doing the job a breeze! Have your kids get in the act. Cut-up some cardboard boxes to pieces of cardboard 18-inches square. Bundle-up 4 piles of 25 squares and bring the 4 bundles and your tank to a body shop. Tell the manager you'll swap him 100 custom 18-inch "Mud Boards" for pulling out that dent. It will be the best deal he's had all month! Your best deal of a lifetime!!!

 

beanflicker_98 all these ideas above are spot on but as mentioned it does depend on what type of dent and where and any creases , so a pic will show we all or take it to undint it at a shop it shouldent be that much... cos after painting everything shows up if not done correctly..
