[chbot] Micromouse wheels

[HARTLEY ROBIN]

Hi Richard,
Try Mico metals. (was Mico wakefield)

For 50mm bar you should be able to find a supplier that will cut in
100mm increments.

For my wheels on steppers I machined them from Acetal plastic with a
grove on the outside for an O ring.

The steppers I used were ex disk drives so has a nice 25mm boss already
on the shaft which I pushed the acetel on to.

Regards,
Robin

I'm wondering how to get hold of some wheels to attach to stepper motors
to
construct a micromouse. The stepper motors are about 42mm square and 32
mm
deep. So I'm thinking that 50mm dia wheels and with rubber or plastic
tyres
would be about right. I have access to a lathe and could turn up some
out
of aluminium. Anyone know where I could get hold of suitable aluminium
rod
or plate? I've been looking at the Nalco site and they have 50mm dia rod
which weighs 5.3kg/m and as their minimum cut length is 1m its probably
going to be pricey. Anyone have any suggestions for alternatives?

Thanks

Richard
