I decided from the get go that since I didn't have the bit required to route a trench for T-Molding...nor did I have any T-Molding on hand...that I was going to just round the edges with my router...being that this was the very first time I had ever used a router (No,  I never had "woodshop" in school...I was always taking Metal Shop & Auto Shop instead)...I think I did a pretty decent job.  To the discerning eye,  there ARE errors...but nothing earth shattering...and as I said,  I have an overlay (of sorts) that I am going to put between the wood and the plexiglass.
In this first photo,  you will see my arcade cabinet.  I have marked in red where I plan to make a cut (approximately...I eyeballed the photo,  I will,  of course,  measure the real thing before i cut).

Next is the backside of the CP.  I still have to route the other joystick...it was getting too late last night for the router (around midnight).   Also note that the route jobs aren't 100% accurate either,  but being that I added about 1/4" on each side,  there is plento of room in there to line up the joystick correctly before mounting.

Here is the front side of the CP.  Again,  the flush-mount trackball plate route isn't 100% accurate,  but it will be covered with an overlay of sorts and then some plexi so it's perfectly fine.

Here are a couple of shots of the plexiglass, I can't remember the exact thickness...it's thin stuff though...thin enough that I use it for my "rounded" marquee...trimmed to the correct dimensions & waiting to be drilled...


Finally...here is the base of the "The Real Ghostbusters" control panel that I was given... it needs a little work (nothing a little bondo won't fix).

Any comments?  Suggestion?
What is the best way to drill that plexi?   I am thinking hole-saw mounted to the CP,  facing down between a sheet of wood...my concern is that I would then be drilling toward the CP face and it wouldn't be flipable if there are burrs, etc....but I think that is the most accurate way to get the button holes right?
