Last week I bought an old Hugh Porter bike, (see my last post in 'classic & vintage). I took it out for a couple of short easy rides and it performed beautifully and yesterday I took it for a longer ride on the North Yorkshire Moors. After 12 miles and a couple of stiff climbs I became aware that all was not well with the right hand pedal. When I examined it, it looked as if it had unscrewed a little way, I tried to tighten it but it was evident that the thread was knackered so I took the wimps way out and caught the train. When I got home I tried to remove the pedal and it would neither screw out or in so I was unable to remove it. I have two questions, 1. How can I get it out / 2. Is it possible to repair the thread using a Hellicoil I would like to retain the origional chainset if possible because I believe they are origional parts and about 40 years old. Many thanks for your help.
