fuel tank dent

[Vegan]

I would be removing the tank from the bike obviously - it's very easy to remove....

[Cibby]

buy a new tank..

Thanks postie!!! hehe

... but hopefully it just pops back to the right shape? What do ya do about the heat from the weld (petrol and all that)? Obviously you'd empty the tank, is that enough?

NO

You will kill yourslef when the tank explodes. A tank CAN be defumed well enough for welding (I've done it many a time) but it is not a trivial task.

If anyone wants to know more PM me.

BUT NEVER TRY TO WELD A TANK THAT HAS JUST BEEN EMPTIED OUT (OR WASHED OUT WITH WATER)

for how much ? $300 or something? fuck that

AWWwwww c'mon Ix - can't I play with fire just a little bit?

A tank CAN be defumed well if drained then hang it on car exaust with motor running untill tank is warm,place tank on ground around corner of shed and wave gas torch over filler,if no bang start welding without delay,have done it countless time and no problems yet

ok so who wants to come and pop my tank out? eh eh eh?

you need to hang the tank by the filler over an exhaust of a running bike/car, im not sure for how long so i do it for ages, that gets rid of the nasty ignitable gases, then weld away, normaly you will never get the same old shape back, buts it's pretty damn close..

Well I'll remember all this once I get back to having a ride! The info is good to store away in the ol' brain till needed.

[crazefox]

mate vi will give it a go 4 u

I knew a bloke a while ago that used a German made machine called a "Spitznagel" [yes I know its a funny name!!] he bought it from the local Snap On agent [google it perhaps?]
What he did with it was to spot weld what looked like a copper plated nail, head first on to the middle of the dent & then he'd use a slide hammer to pull the dent out & then just grind off the nail head, neat quick & simple

[Motu]

Yeah,cool weapon those...I've used them to pull out dented sumps.It won't pop right out,and filler will still be required.

[Colapop]

What if ya add more than one pin?

with a tank that has the pump in the bottom of the tank flange mounted ive just pulled the pump out and banged the dent with a drift and hammer , on one of my many munted ****ed up tanks from rollovers ive cut the underside out with a very thin cut off wheel , banged it out with various hammers .


caution with petrol when cutting and welding, i emptied my tank then let the car idle and rested the filler cap on the exhaust outlet for 1/4 hr to evaporate fuel and flood the tank with co and co2 , when i welded it back together i drifted nitro thru the the tank , it lowers oxidation and soot and makes sure any leftover fuel has no oxygen
