Hi Vic

Great stuff. However, i have the HEQ5 mod kit from belting online, I had to bore the 9mm holes up to 12 mm. I am now in the process of sizing up the brackets. This thread will be a  great help to me. Thanks very much.

Ah, cool - i understand it now. Is it possible of the photos of the custom pulley set up. I have an EQ5 mount (not the HEQ), so have gone for the same kit as Raoul, the teeth and belt specs are different to your sketchup plans. would i have to account for the differences.

Cheers, and thanks for the speedy reply.

Hi Raoul and Tom. Have just got the stepper motors,  NEMA14 motors and the kit from BeltingOnline. Will be going to make the brackets, have the Skywatcher EQ5 mount with the dual axis kit. Can I ask if you have any photographs of it all set up on your mounts, so I can visualise what it should look like. Very much looking forward to this as I am currently stuck with with the slow slew rate of the dual axis kit. A photo would be a tremendous help. I have already made up the control box, only difference I did was to use red, yellow and green LEDs

Out of interest, I tried altering the voltages on the stepper motor drivers, I think i set them to around 2.5v and the dual axis kit motors got really hot - what voltage should I set them for the new steppers.

Cheers and thanks very much
