Tip for next time: thermal expansion of aluminium is bigger than steel. Add Q10. Cool the seat post with ice. Heat steel with friction, work quickly to loosen aluminium part. Worked a charm when I had to remove quil stem after 34 years

The only reason I had to remove the seatpost, is because it broke off at the seat tube, there was about 5mm of aly sticking out, not enough to properly get a grip.

I proceeded to use a hacksaw blade to gut a groove over the course of 2 days. The last little bit of the post I thought I could persuade to shear along the groove with a hammer and an very long flat screwdriver. The Aly had a different plan. Seat tube cracked due to the screwdriver and aly having had a disagreement over who is giving up.

I’m getting the frame back on Monday, will post pics before I take it to Steve’s guy. I still hurts that I did that to my frame.

Pic attached of broken seatpost straight after accident and More or less position of the crack in the seat tube.

duct tape and cable ties .................... all you need :P

Whatever they use, you may need to ream the seat tube after the repair as some material I am sure will "seep through" the crack.
