Today was my forty-somthingth birthday and I booked the day of work thinking it could be more productively spent in the workshop and Indeed I have almost finished making the magneto platform for Scott SE.
Sitting back admiring my work and running a finger over the mag chain, I idly rocked the flywheel with my other hand. Ouch! Getting ones finger between chain and sprocket hurts. So now I'm waiting to see if it will just go black or if the nail is going to fall off. I always thought you live and learn, but it would appear not:-(
I think I'd better take a little liquid anaesthetic before going to bed:-)
