The Joy of Improvised Wheels

[ksquared]

As the tin implies, I was trying to make my own wheels.  My best  (I think) idea at the moment was to pack two large washers onto a short cut-off from a wooden doll and put a rubber band over them (if that becomes an issue, glue the Rubber Bands.  What kind of Adhesive? )  Not that I'm precluding manufactured wheels. 

As it were, I figured that someone else might be so kind as to share some other schemes that might be used to construct them.  I tend to find mechanical schemes in general interesting and enlightening, and I would appreciate all ideas.  PCV pipe, wood, you name it.

Thanks!

Contact cement should suffice.

What diameter are you looking for?

[ksquared]

2 or three inches, since you ask; although I could take a little larger. 

Gracias, Señoir.

I'm certainly not against improvising when necessary, but you are wanting a very common wheel size.  There are hundreds of cheap wheels out there of that size.  Why not just drop a couple bucks on already made wheels?

Here are my CD wheels:

3CD's fixed together in screws for a wheel.

cardboard and rubber bands, CD's, circular things from old stuff like a heat changing dial on a microwave.

Self-Hijacking (to cut down on threads): How do you mount those tiny metal shafts to wheels, or even anything else?  Also, does anybody have any good techniques for mounting the motors themselves to anything?  Not that I'm not still into wheels.

And thanks again, I really appreciate the help I've been given so far.

Also this could be kinda useful, but still: http://www.societyofrobots.com/mechanics_chassisconstruction.shtml#wheels
Contemplating the first method. 

[SmAsH]

To mount a motor to a chassis, or anything else for that matter, most people use a bracket...
Does the motor shaft have a shape to it, or is it just round?

[ksquared]

Round, but two would be basically flat bodied with semi-cylindrical sides.  But these brackets you say... what exactly would you be referring too?  I suppose I could use some simple ties and contact cement.... not sure exactly what kind of ties I'd be using.  I'm open to ideas.  (Jury is still out about attaching wheels to motors.  Servo Horns?  Finite Supply.)

Thanks Again!

About the mounts, something like this would suffice:

well i made some here

they're really good and they only need cardboard and just about any adhesive you have. if you need tips on how to make them then let me know
