Sorry I haven't posted on my project until now, as it is in a close to fully constructed state, but better late than never. The intention is to see if anyone has any suggestions that will help me avoid future problems. This is the current state of my project, and has been for the last 2 months (this is what having a newborn will do to your hobby). I have built this from scratch from MDF based on the Ultimate Arcade II cab using a 27" TV (and possibly an arcade monitor later). I planned the control panel off of something like Delusional's, but without double 8 way sticks. Currently I am debating on admin buttons and whether to throw a 4 way in there up top (and where to put it, as I'll jack up my hand playing golden tee).
From my short experience, I can tell you these mistakes that I have made:
1. Building the cabinet before discussing where it will go with my wife. (Ugh, no basements in San Antonio) So possibly garage and I'll wheel it into the main area through the front door for parties. Or I can put it upstairs in our room. This one already has me thinking of building a second cabinet to put in the office that will fit through a narrow door (like the slim woody by Knievel).
2. Routing the slot on the cp before buying the plexi that will go on top of it. Really the plexi is thin, but hind sight was definitely 20/20.
3. Building it all out of 3/4" MDF. HEAVY, and only place it can go inside is upstairs. The neighbors are going to hate me. A case of beer may be in order. Speaking of which, I could almost fit a kegerator in the arcade. Hmmmm...
Note in the pictures that I modified the cp to include a slimmed out area that will have "flipper buttons" about where they would be on a real pinball machine.
