Need Concave Wheels 3/8" Wide.?

Basically it needs to be 3/8" Wide at the concave part, and preferably from amazon. Can't find anything that wide though. Help please? I need it soon, to meet a project deadline for school.

Now the problems here expand. You don't say where you are.

You don't say what they need to be made from or what weight they need to carry
You don't say how wide they need to be at the rim
You don't say what diameter they need to be.

1. Lots of engineering companies will carry wheels that may or may not do the job.

2. A little work on a lathe or with a belt sander and some wood may do the job for you.

3. Ask your teachers they will have resources.

4. Does it HAVE to be concave? It's an unusual requirement.

5. If the task is light weight can you use layers of card.


This is really YOUR project and YOU have left things late in the day to discover you can't get a vital component. Start thinking of solutions.
