As soon as Norm and I decided to build an arcade cabinet, we ran into a problem: We didn't actually know how to build an arcade cabinet. We knew what we wanted, at least in general--a four-player MAME cocktail cabinet that could support fighting games and beat 'em ups and pretty much anything else we could throw at it. How hard could it be to find exactly what we wanted online, then replicate it at home? Turns out: Pretty hard.
ArcadeDepot, one of the most popular sources for arcade kits, was knocked out of commission by Hurricane Sandy. The other pre-built kits we looked at didn't offer customization. That left user-built arcade cabinets to work off of. The Arcade Controls forums and wiki are great resources, with one unfortunate downside: Many of the projects linked on the site now lead to 10-year-old dead webpages, and most members only upload photos of their homemade arcade cabinets, sans dimensions or detailed blueprints. That left us with one good option: the detailed Pac-Man cocktail plans and assembly instructions created by Kyle Lindstrom.
Most cocktail cabinets are heavily based on the original Pac-Man cocktail, with a few tweaks here and an added control panel there to support two extra players. To make those tweaks, I decided to recreate the Pac-Man cocktail cabinet in SketchUp. Once I had a 3D model of each part, it would (hopefully) be easy to piece them together, add another control panel, and change some dimensions while making sure everything still fit together.
After recreating the cocktail cabinet in 3D, the next phase of our build could begin: Creating a cardboard mockup, to make sure the dimensions of our modified design would give us enough control panel room. The cardboard build would also give us a good visualization of how the planned 19-inch arcade monitor would look in a slightly enlarged cabinet.
SketchUp is a free download, and offers templates upon startup to work in millimeters, inches, feet, and so on. I started with inches, and spent a few minutes fiddling with the 3D camera before settling on a top-down perspective. Then I started drawing each Pac-Man cabinet part in 2D.
