A straight edge won't work...unless you can figure out how to attach it perfectly square to the rear sprocket.

I'll be home all day on Sunday building RC planes with my friends. you're welcome to the garage then. Sash is heading over now so we can wrench on his bike and get it fixed. You're more than welcome to join us.

I just hold it up touching the sprocket closer to the axel so that there is more area touching, basically works the same way as that thing.
