Not a problem. I love to answer questions. Brad has all the dimensions written down somewhere for the inventor so he can post it.

3 2/3 hrs till i leave for annapolis!!!!!!!!!!!!!!!!!!

Congratulations on your stellar performance in Annapolis! Sorry I missed it. I see that you won every match, and seldom got less than 100 points. Very good numbers. You also got some awards - excellent work. Was one of these for your transmission?

Regarding your transmission, I want to clarify the size of the ball bearing that you use - is it 5/16"?

Also, you mention that there are 2 different size holes - I guess these are the holes through which the balls protrude. Can you describe what you mean by 2 different sizes - are the holes stepped - that is the entrance hole is bigger than the exit - so the ball doesn't come out to far?

As far as I know we recieved both design awards for our tranny at Annapoilis, I was not there, but I did get word of our acheivements. All of this was because of our Mechinist Bob. Unfortunatly, due to weight issues, we only had 2 gears ( I am unsure of this, please correct me if I'm wrong) to run with, but still the tranny proved it's value. THANKS BOB

Actually, we did still have three speeds. Removing a set of gears was something we talked about before shipping while sitting at the usual 132# with three days to go. Like always, we managed to loose weight without sacrificing vital functions.

On the awards...Friday's Delphi Driving Tomorrow's Technology award was primarily for the tranny and the way the students were able to describe it to the judges.

Saturday's Motorola Quality Award was the combination of the tranny, the robustness of the machine and the applicability of the overall design to the game.

I am glad to see Frank has rose up from the dead. He hasnt posted in years.

Yes their are 2 different size holes. The bearing 5/16 and they are steel. The first hole is the size of the bearing and is drilled partway down into the hollow shaft. The 2nd hole is all the way thru so that the bearing doesnt fall down thru. This hole also allows the bearing to protrude thru the hole so we can push it up thru. I do not know the depth of the first hole or the diameter of the second hole. sorry
