I made my super-sized sprockets a bit differently.

Its poly-carbonate lexan.
Metal sprockets make quite a racket of chain jingleing noises. On something with a loud gas engine, you don't notice much, but on something with otherwise quiet motors, it becomes pretty annoying, and non-metal sprockets can keep noise to a minimum.
The lexan is way way stronger than it needs to be for this wide of a chain and sprocket diameter. Only the outside few inches is lexan, and it bolts onto an aluminum adapter to mate up to a splined eno freewheel to slide right onto the cassette of a rear hub.

That's a brilliant idea, PJIII, turning a sawblade into a giant chainring, but can you say a few words about how you shaped the teeth right? Or was it just "freehand genius"? If you have some pointers about how to achieve that uniformity of tooth shape, I'm sure folks would like to hear them. Thanks.
