This is a guess, but my guess is...

As the older freewheels become more scarce, we will all become more adept at rebuilding them. Nice write up and thanks for introducing many of us to the simplicity of it all. Frankly, I have often thought about rebuilding a freewheel, but I have always fallen prey to the "it ain't worth it" argument. No more.

I like to get my bicycles as close to perfect as I can, with my limited understanding of them. I have always wondered about the freewheel, and, as part the rolling gear, it needs the same attention as do a set of wheel bearings, in my opinion.

Thanks.
