Last week was a busy one, not much time to work on the ELapShelf project.
I found a nice gear set from an old printer that should work for the shelf control.
The small gear shaft was smaller than the shaft on the kit motor however, so I had to make a new shaft adapter.
Here's a picture of the gears in place on the main arm and shelf.
Here's a picture of the assembly with the gears installed.
The arm is made from oak trim so it is strong but not too heavy, and the shelf is a sandwich of
thin spruce plywood covering a foam core with a balsa wood trim.
