Is it TOO LATE to have my head EXAMINED. I own

Greg I have had some success with compressed air with shallow dints like that on the KT. I did a TL125 tank and blocked all the exits & at first I put too much air volume in and the tank splayed out somewhat.
However the process did work after having to re shape the tank back.
Chippy, I too have splayed out a TL 125 tank, the arch inside is fairly straight so not much to stop it opening up. One of my TY 250A tanks had been pressurized by the previous owner and the side effect was to make the tunnel so small it would no longer fit over the frame.
After considering the suggestions and what I had learnt, I made a jig to hold the tank with timber and packers in the tunnel and wrapped ratchet straps around each end to stop it spreading.

The actual problem is that with compressed air you can't control WHERE the expansion happens, so it's just as likely to split a seam or push out a good area as fix the dented bit.
Maybe if you heat the dented part to soften the metal there then pumped it up...
I'm a sucker for the sucker.
Jools, that sucker would be good on big flat panels like the side of a van but would not seal on ripples.
However I do have one of these:
So with a little help from some offsiders, a combination of pressure inside the tank and the little sucker pulling, we were able to get most of the dints out. Good enough for this old girl and I like the 43 year old patina!
Now I am considering Rare Earth Magnets for the crease near the top. Maybe one on the inside and one on the outside with a pulling hook?
