The seat post was stuck on this when I picked it up.

I’m not  keen on using chemicals for extraction,

A ) because of the probable environmental impacts disposing of caustic soda and

B) I don’t want to risk damaging the frame paint ,

so I have opened up the seat post clamp lug

and will soak with penetrating oil for a few days..

Well, this has to be the worst case I’ve had so far.

I really didn’t want to use chemicals, so I cut, rasped and reamed..

My friend is an engineer, so I took the frame to him, and we tried our best..

but sadly a crack appeared on the non drive side area of the seatpost clamp collar, so I will see if I can repair with a tig weld, luckily,  the frame is constructed with tig welding, so won’t look too bad.

(I hope).

Well…

I spent a little time filing and sanding to get as much of the original contour back as possible..

so just a little more, then I will have to resort to chemical extraction.
