Spent a couple hours making chips last night. This the plate that the Dec motor and gearboxes mount to, it attaches to the big harmonic drive. I still need to counterbore for the screws.

And some video of chips flying.

The part is 8" wide and 14" long.

Made the motor and gearbox mount tonight. One little goof. I entered a .1 when it should have been a -.1 and started a bore shifted but caught it early.

Next up is building a losmandy style saddle and the frame for the RA drive. Starting to get a bit heavy too, up to about 50lbs now.
