Googling for "diy motorized camera dolly" may turn up some additional hits.

servocity has lots of good parts for things like this. They have belts, gears, motors, servos, and controllers at reasonable hobby prices. Not sure what the UK analogue to servocity is, but it'll give you an idea for what's out there:

What kind of help are you looking for? Design? Sourcing? Assembly?

[andy_con]

all i really need is a motor with control, so forward and backwards.

needs to be a smooth slow motor, so maybe a servo motor? im not up on motors and controls so any help would be greatful

Sounds like a job for T slot tubing with teflon sliders.

go to this link and click on the "fractional linear motion" link.

Other companies offer similar.

Then get the motor and plastic chain from "SERVOCITY"

cos thats all i want to do, make the motor turn forwards and back

90% probability of it working if the PWM frequency is low enough. Ask the seller what the PWM baseline frequency is.
Too high and the motor just acts as a pure inductor and does not spin well.

3RPM on a 2" pulley is only 18" per minute... is that what you're shooting for?

[andy_con]

ill ask the seller Steve thanks.

tribble, that was just the first motor i clicked on, i would go for a higher rpm probably around the 50 mark

Andy,
have a look here:

They do dual axis quartz tracking motors for £99. There's also a fully auto mount for £199. Compared to stuff by Meade, that's bloody good.
You've probably seen it already, but there's an indistructable which is based on a Meade mount similar to the one above
