Can I squeeze a track ball in there?

how big of a foot print does a spinner need? I do sorely miss Arkanoid.

If you get the GGG turbotwister spinner (highly recommended) the footprint is the same size as a regular arcade button.  You'll need somewhere below the panel to attach the PCB board, but it's very small as well.  That should fit fine.

I just finished building my CP.  I have what used to be a Centipede cabinet that has long since been converted.  I built mine with 2 players with 7 buttons each and a 2.25" Trackball.  The CP on those is 23.75" wide.  But, there are two supports under the CP that are 3/4" on each side, so really I have 22.25" to work with.  I built it about 10" deep, but the front piece of MDF takes 3/4" off the depth, so I really have 9.25".  I am using two U360s so I don't have to worry about joystick microswitch clearance. 

I have attached my Visio template for you to use.

Instead of a Tornado Spinner like in the template, I am going to use a TurboTwist 2, but you can see how a Tornado would fit there (it takes a 2" x 2" footprint).

I even had room to have a row of buttons at the top.  I am only putting the Player 1/2 start buttons and two in the middle which are mouse buttons.  I have the shift button under the bottom of my CP box and some pinball buttons on the sides.

It was a really tight fit, but it can be done.  Should be better for you since you have few more inches to work with.  Hope this helps you a little.

Plus, you have to factor in a mounting plate if using a wood panel.

That is at least 6 inches

PsychoAU:
Yep, I had to factor that into mine.  2.25" trackball has a 6" mounting plate.  3" trackball has a 6.5" plate, I think.  I managed to get it all in with millimeters to spare.

The same mounting plate works for both the 3" and the 2.25" trackballs.
