I currently have a 2 1/4" trackball, Instead of buying/making a tb plate, I'd like to route out space for the tb with my dremel, I dont own a router.
Is this possible....
Dremel can route, but I think a major point is being missed:
The wood is not strong enough. 2 1/4" TBs have a 1/16" lip; that's how thin you'll need to route the wood to have the ball all the way out. Once you let the wood stay thicker, the ball will be that that much lower.
You could support the TB case from underneath or the sides, but even then 1/16" wood is prone to crack, chip, or flake off.
A laminate/lexan/plexi won't chip like wood. But 1.5mm ~= 1/16", so even with a 1.5mm-2mm thin lam/lex means you should cut all the way through the wood in order to get all of the ball above the CP. (You should have at least some support from the bottom with laminate on the top, too.)
So, IMO, the answer to the first question is no, making the question on dremels for your CP mote. [shrug]
