1. I assume the green wire off the trackball is the ground correct?

If the Imperial trackball is simular to Happ then that green wire is the static ground.  According to  Happ static electricity can build up in the trackball during use.

This is correct.  Contrary to common belief, however, this has little if anything to do with protecting the electronics or the user from shock.  This is to prevent static buildup in the ball from attracting dirt and debris and the subsequent transfer of that debris to the rollers inside the unit.  A dirty ball and rollers will perform poorly and wear faster.  The EI ball material is less susceptible to this type of buildup, but you may want to connect the wire just in case.

When looking at the ball-side of the unit, the wires should exit at the lower right corner.

ok thanks, I guess I would have mounted it upside down.

What is the preffered TB size 2.25" or 3"? Why?

I'm completely rebuilding my control panel because of lack of planning, poor design, mistakes, addition of TB & Spinner and and on and on...Hopefully i will get it right this time!

You can also route a to within 1/4" of the top surface and secure the body of the unit with L brackets and short screws.  Just be sure to stay away from the corners of the housing.

I have seen others use a roundover bit inside the large hole for the ball and it looks very nice.

I already have some carriage bolts in stock, and I will be getting some top plates made soon for those you don't mind that look.

When mounting the Electric Ice in the fashion listed above...What should the approximate diameter of the trackball hole be?
