What bike are you talking about from this site? The rear axel is something you can buy from a go kart/mini bike supply company. It is a long bolt so you may be able to search your hardware store. Im not sure how to help you wiht the clutch, chain and sprocket as im not sure exactly what you need help with. Mont the enige with the clutch on it. Mount the rear tire with the sprocket. Now line the two up and put the chain on. More info about what bike your making and exactly what you need to know will help. Any pictures?

Maybe you canbuy a mini bike kit and assemble and paint it custom. Thats a good project, simple as well. You could document each step with pictures and a write up and present it in class. I did that with a go kart i rebuilt when i was in an ag class in 10th grade.

A hub mounts to the wheel which rolls on the axel. Get a clutch, sprocket and chain and make sure they are all the same. For example, they are all #35

With any custom project, you have to start with the wheels. Get your rear wheel mounted up good and straight. Next, place your motor on the frame, but don't bolt it down. Get a ruler or a straight-edge, and set it against the clutch gear and the rear wheel sprocket - make sure the ruler is flat against both. Mark where your engine sits, and if you can get to them, where the bolt-holes go. Set the engine aside, drill your holes (maybe go a bit oversize for a wee bit of wiggle room, just in case), then mount it up and bolt it down. Cut your chain to fit - as someone else pointed out, don't mix and match chains and gearing, keep it to one size, period. If you have a #35 sprocket, make sure you have a #35 chain and front gear. (I believe #35 is the eneral standard for minibikes ....) Some engine shafts have keyways, where a little piece of metal slides into a groove on the shaft and into the gear to hold it in place.
I've used the straight-edge idea a couple of times - I have a metal ruler on a T-square (another important tool for building straight frames). It's saved me a lot of headaches and broken chains.
