Getting toward the business end of a project and need to address the requirements for a dual axis drive system, but not a lightweight.

I need to control a English Fork that weighs about 150kg, (90mm polar axis) and the Dec axis' are 50mm. The OTA weighs in at 130kg+ and 2500mm long. Permanent observatory.... as you'd guess.

I am figuring the starting point is a couple of Byers type gear and worms but that's as far as I have got at the moment.

Anyone out there have experience working on hefty mounts who can share a pearl of wisdom, or 20..., I'm all ears
