Hi all; got a bit of an update with some of those previously promised images. Here are all the shots of the current design as it stands. The motor mount was the only one that caused any problems as it required a ton of finicky measuring. This design uses this impact wrench. I like how this works as it lets you remove all the plastic. It also lets you remove the nylon spacer that holds the bearings, gear race, etc. It really makes everything sturdier by making it all a cohesive aluminum unit. This thing is now bullet proof.
The final image shows how it all comes together. What's next is the changes needed to add in the solenoid mounts, limit switches and electronics. Please let me know if you have any questions, comments, or ideas. Thanks!
