Now I am on to the mechanical part of my EQ6 Mod. I have a couple of drive mounting plates but need to source the gears.

I took a look at the ones in my goto Atlas and they are a 12 tooth gear on the stepper shaft and a 32 tooth transfer gear that meshes with the gear in the mount attached to the Worm gear.

Anyone know what these two gears are pitch wise and where I can find them.

Thanks

Terry,

Depending on your budget you might want to look at using the Rowan Astronomy belt drive kit.

This replaces the gears completely and provides mountings for NEMA 17 stepper motors. I have attached a picture of my motors in an early non-goto EQ6.

[NOTE: Don't use the steppers in the picture, I had issues with them after I took the picture]

Thanks Phil. I did look at that and decided I did not want to do that much disassembly on the mount, it had been hypertuned by DSS so was in good mechanical shape. I bought a set of EQ6 motor assemblies from Skywatcher in the end. Not cheap but at least I know the gearing is right.
