Thought you guys might like to see this, bought an original 80's Cinelli stem on the bay and had a guy I know threw the BMX world give it a make over (polish) I'm well pleased with the results and if any one wants his details just shout.
Polishing alloy stuff always gives a new lease of life to a part which would have found
itself in the bin, recently renovated an old Cinelli stem which had been clamped in a steel
vice, so the upper & lower section & sides of the clamp area had very bad and deep cross
shapes caused by the vice, It was clamped in a vice so the stem would 'crack' free, after that
it was being thrown but I saved its poor little life by filing out the bad marks and re-polishing up.
You get great satisfaction from doing this don't you Maca
