Your site is a great inspirational resource for me, and since I work as a physics teacher I decided to build a marble adding machine for an annual school Science Fair.
I modified your design slightly, mostly in cosmetic purposes and it works flawlessly from the start. Great conversation object and great fun for my kids!
I kept mine open at the front so I could always reach in and tweak things, but most of the problems involved marbles bouncing out the front.
