Washers on Sprockets

[pbawesome]

a spacer would be best. measure out some low profile nuts (or normal nuts if you need alot of spacing) and thread them onto the wheel then attach the sprocket. The washers are a really bad idea! the sprocket may go all over the place and knock the chain off!

so use either nuts or turn down some spacers out of PVC

Spin the wheel without chain attached to it. If the sprocket doesn't wobble, you're fine. in other words, if the sprocket is perfectly parallel to the wheel, you're fine.

If it does wobble, then consider shaved off washers as shims, or use spacers as suggested above.

Looking at the pictures, it looks like they might be springs, not washers....
