I've been planning to do a cab just like this for about a year-and-a-half now, and just recently got the monitor for it.
My plan is to have steering wheels on 3 sides, and get it set up similar to Sprint 8.
It will be a modular plan, so that I can swap out whatever I want, wherever I want, as well.
(2 wheels front, sticks on the side, trackballs anywhere, etc...)
I plan to use it AS a cocktail vertically, but an upright horizontally.
My concept is basically a standup cocktail, that will convert to a Candy Cab.
Here's a sketch of my tilt-up concept.
I was just going to use a piano hinge at the front, and a stop block at the rear (with locking pin holes to keep it from popping out, and crashing down).
My monitor weighs 110 lbs. bare, so I'm guessing I'll be pulling somewhere around 60 lbs. to tilt it up.
Not a big problem for me, but could be a problem for others.
