I’ll get some pics of mine today, just making up a second spacer for another bike. Works very well, though the quarter inch mentioned in the other thread is just a little big I reckon, I ended up relieving the edge slightly to lower the exit angle and effective “height” and it’s almost perfect.
Washers worked fine but were a wee bit of a pain to work with. (OTOH, I’m the worst machinist, so while firing up my toy lathe I had my usual thoughts- “Most people couldn’t do this, I’m so awesome” and also “Everyone else in the world who could do this would do it better”)
Anyway- doing it with no spacer just doesn’t work. Some people are used to having gears that are rotten, and they might be happy with it- you get a few gears that work fine. But it’s like having a twisted mech or totally knackered cables. You know that mate who insists his bike’s in great shape and you’re all mad for spending money on new parts? He’d get on fine.
