So this is how the project looks today.  I have been practicing with routing out an area on a scrap piece of wood (1/4" out of 5/8" MDF) for the underside of the control panel for the joystick.  I am concerned about the strength of mounting the joystick with only about 1/4" of MDF left.  I think I am going to also get some metal strips and mount then under the joystick and screw them into the full thickness of the wood.  It seems like it will work.  Also, I ordered one of the Oscar Controls Vortex Spinners that showed up on Ebay this week.  I got it two days ago.  Great product.  I was impressed with the quality.  If you are looking for the Vortex Spinner the ones on Ebay are the real deal.  Last I looked there were 4 left.  From Happ, I ordered the High Lipp trackball and special mounting plate.  I'll pr active routing out a surface for the mounting plate on a scrap piece of MDF.  Also on order is the Hagstrom ME4 optical encoder and now that Ultimarc has the Ball Top J-stik, I plan on making a large order this week for the ArcadeVGA, J-stik, and Ipac4.  If anyone has any questions or wants to see some more photos that I took along the way, just let me know.  Hopefully this will all be of some help to others.
