Hello Philip,

No problem, I can make you one. Does 21cm/second sounds good to you? Or do you want to go less speed?

What others specs do you have? Track gauge, Height of the pulley?

pricing is 900 till 1500 depending your demands and how much DIY you want to do.

Please call me: +31653201455

Best regards,

Onno

Here is a DIY slow torque motor dolly i did..
At the end of the first video you can se some stills of the motor i used.
Its a regular 230v mirrorball motor. it moves at about 12cm pr min.
to slow it down to 6cm pr minute i did a pulley system with two strings.
