Re: Dropout extensions... where to buy?
Thanks for your thoughts on this. What I was picturing was bolting the extensions on, but having the extensions open at the rear so the wheel could come on and off, with adjusters to get the chain tension right. In other words, it would be like it was, but further back. The problem is in how best to join the extension to the existing dropout. I"ll post photos of what I have in mind. A good thing now that I think about it, is that the AMF dropouts are of the vertical kind, so a bolt through there and into a hole at the rear of the extension plate would be pretty secure I would think. As you said, a smaller bolt or two elsewhere on the plate and through the AMF dropouts would stop any up/down movement. Maybe welding isn't even necessary. Don't know.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
