I've got a frame which for reasons of butchery needs a new seat-post tube (the top of the existing one is missing, or largely missing).
What needs doing (I think) is a steel tube needs interference-fitting down the existing tube, leaving about 3/4" exposed, which would then need a couple of slots cutting into it, and that would be the NEW seat-post tube, obviously with an undersized clamp.
Questions:
Does this sound like a sensible way of restoring the frame to good use?
Is it a job for a good local bike shop, or do I need an engineering works?
If the engineering works, then the biggest problem in NW London is that there aren't any, any more. Used to be several, but over the years they've gone the way of all. Anyone know of any such places in this area?
Thanks.
Allen.
