Its been a long time since I updated this thread.
Year 12 has finally begun and I can start building this thing!
So what has happened in the meantime?
- Design is 90% complete. Figuring out holes for the latitude adjustment and holes for a Dovetail saddle plate (I would make one if I could find some details and specifications for designing one, but if not ill have to buy something like the Williams Optics one)
- Decided on a tapered bearing at the rear end (32010x) and a needle roller bearing at the front (NK50/25), mostly to make it easier for me design wise and I felt that it would be redundant to have another tapered bearing at the top when there is a thrust bearing to take the axial load.
- Nema17 motors go through a 4:3 gearing system to drive the worm.
- Worm is going to be mounted on easily available skateboard bearings(they may not be designed for this purpose but having skated with them and seeing how smooth they roll at low speeds makes me confident that they'll be alright to use)
- It is going to be running EQAscom with an Arduino mimicking a Skywater mount through the AstroEQ software, for the time being.
- All bearings and moving parts have been bought - just awaiting delivery*
* The size of the tapered bearing is much bigger than what i had imagined but the measurements all check out. 
(I had the drive system mounted on the design before but decided to take it away because it was just getting in the way when i was modelling it)
But yeah, just thought I'd update this thread.
