1. I think I'm above the average person as an all around handy man but haven't done any woodworking in probably 15 years. Do you think building two cabinets at the same time and expecting a professional finish is unrealistic for me (or anyone without much experience in woodworking)?
If you have an area where you can make horrible dust clouds without recourse, invest in an extra sheet of wood and make one nice side template that you can use to make all four sides. Then use the template with a router and a flush trim bit to make your sides. As long as your one template is good, all four sides will be perfect. This is just wood we are talking about. If you mess something up, you can just bondo or buy a new sheet of wood.
3. Since I don't have Maws to filter games, could I have some opinions on which cab (or both) I should add a spinner or trackball to? I definitely want the Golden Tee games (which I believe are all horizontal) and definitely want many of the bowling games (which I believe are mostly vertical), so that puts a trackball on both cabs. What about the spinner? I love me some Arkanoid and other breakout type games, but really cant think of many other spinner games off the top of my head.
World Class Bowling is my go-to bowling game and is horizontal. People who like Golden Tee usually prefer it to any other bowling games.
It's an awesome party game.
Me personally, for the horizontal cab I'd have a street fighter layout with a trackball in the center and a spinner for each player (to play racing games like Ivan Stewart's off-road and super sprint). The joysticks on the horizontal cab would be best suited for fighting games and beat 'em ups.
For the Vertical cab, I'd have 2 joysticks more suited for vertical scrolling shooters (shmups) and then a dedicated 4-way pacman style joystick in the center. I'd probably only have 3 buttons per player on this cab, so I'd use the extra room to give the 4-way joystick it's own set of buttons.
There was only ever one gun game with a vertical screen IIRC. It's Fast Draw Showdown and isn't emulated. There was supposedly a PC version released, but in all my searching I could not find a copy or even a picture to prove that anyone ever owned a copy. So the guns would go on the horizontal cab.
5. Could anyone recommend a good cabinet to copy for a 2 player + trackball/spinner? Don't want the controls to be crowded.
I have tons of cabinet plans... I was thinking a mortal kombat cab or maybe a sunset riders cab since it was a three player cab and would give the extra room for a trackball.
I usually use the x-arcade tank stick as a point of reference. I used one for years and felt it was pretty comfortable.
For two joysticks and a trackball, it's about as short as you can get and not feel cramped at all.
If given room to work with, I use it as a starting point, then go wider as the CP allows.
