BTW, I was reading the title as 'build a long freewheel' and had no idea what to expect until I realized it's about re-building a freewheel!
I've always thought it would be great to have one place on this forum where members could place these type of tutorials. I'm sure there is a place somewhere, but as long as it is not separate from all the other postings these kind of tutorial postings will continue to be all over the place.
