Hi guys,
Well I have rescued my Sunn Radical from its place in the shed at home and have started stripping it down.
However, some how over the years I seem to have installed a set of Mavic cranks which have completely stripped extractor threads. I have tried cutting new threads and using a new tool but there is no material there...
Hammering on the cranks has also not done anything.
I would like to save the BB and obviously do not want to mark the frame (chrome), ideally I would like to save the cranks too, but all I can think of is cutting them off.
So retro-gurus what suggestions can you offer?
Please let me know.
Cheers
Ed
