Is this salvageable?

[Steve1975]

This is the damage done to my Al Carter whilst removing a stuck seat post. Do you think it would be repairable or safe to ride with a long seat post?

Was it an alloy seat post stuck in a steel frame?

Yes it was

How did you get it out?

I filed it til it was about 2mm thickness then a mate took over and drilled it out

In the 2nd picture what is the state of the tube? Is that just the paint or has the steel tube been stressed there?

That's the tube. The paintwork is a bit hammered but the lump is all tube

I think you could dress the tube and clamp at the rear with a mandrel IE (gash seat post) inserted, then file the slot and stress relief cutout to tidy it up and stop the crack spreading. However the bulge in the front of the tube is suspect. Sadly mangled.

I tend to think it's definitely ruined but I've had it a long time and hate the idea of a new bike

With a combination of alcohol and a chainsaw by the look of it ….
