Programming: Nicholas & Julie worked on communications issues with the Samantha. These were not resolved during the meeting.
Mechanical: Rebuilt the arm drive by replacing the original 4.7mm D-shaft with a 0.25" diam steel shaft with 3/32" keyway. His change required the following:
- Bore out the driven brass worm gear to 0.250" ID
- Broach a 3/32" keyway in the worm rear ID
- Drill the output shaft bushing holes on the worm gearbox to 3/8" (from 8mm)
- Replace output shaft bushings with 0.25" ID bronze flange bushings (1/2" long)
- Cut (3) 3/32" keys: for worm gear and (2) for Hubs
- Assemble output worm gear and shaft w/ key
- Re-assemble input shaft with dual motors and worm
- Bore (2) driven Hubs to 0.250" ID and broach 3/32" keyways
- Reassemble arm drive shaft (including tubing portion)
