Rotating monitor - Yet another take

This would allow room to mount 4 blocks on either side of the monitor. These blocks would extend out flush with teh front of the monitor.
You could then cut out a round poster board circle (the thick foam filled stuff).
You would cut out for the monitor viewing area in the center of poster board.
This poster board would be big enough to cover the gap between the round wood disk and the monitor panel of your arcade. The rest of the poster board would cover the entire monitor panel.

Sort of like. . . this?
I'm looking at building a wooden cage around my monitor, effectively. It will be a panel-mount monitor, so it will actually attach to the front piece of wood. Four blocks will connect it to the rear piece, which in turn will connect to the lazy susan bearing, which will connect to the board in the cabinet supporting the whole assemblage.
It could work just the same with a rear-mounted (VESA) monitor. In that case the monitor would attach to the rear circle instead of the front one. But the front piece would still be required to support the rotating part of the bezel and for the user to push on. It has to be solid because that's what the user will grab onto when he rotates the monitor. (It's done manually in my plan, as you know.)
There will be some sort of knob or a hole -- not shown -- in the front circle where you can grip and give it a push. So it has to be strong both in front and in back.
I was wary of desktop LCD monitors because I could never find out whether the VESA mounting point is centered, whether it requires access to the front panel to adjust, whether it will come back on after losing power, etc. With an industrial panel-mount monitor there should be a lot fewer variables.
The bezel will be another thing. My hope is to have a circular bezel made of laser-cut tinted acrylic that moves along with the monitor, and a slightly overlapping frame of laser-cut ABS around it.
DaOld Man:
yeah that should work.
I am going to use blocks from the circular board to the edge of the screen. (Im using a CRT).
I can then attach the thin poster board cut in a circle, to the blocks.
This should give a plush appearance.
Plexi will go over all that.

OK, I found an hour last night and tried mounting the monitor using the lazy susan bearing. What a huge pain!!! I mean it was easy to do but I encountered a few extra steps I didn't think about - first and foremost was after attaching one panel to one side how do you attach the other panel to the other side??? I worked it out but I had to drill a ton of holes. As for the rotation... I'll let you know. I bought some 1" machine screws to mount the monitor but they had the wrong threading so it's off to Home Depot today to try and find the right kind...
I'll do a more "formal" write-up with lots more pics once I sort everything out. Also, my camera totally blows. Everything is out of focus and 1/2 the pics I took are useless.
Picture 1: Cutting the circle was fun. I made my own router table/circle cutting jig and it came out OK. Definitely good enough for this project. The board just pivots around the center pin - easy!
Picture 2: Here you can get a pretty good look at the lazy susan mechanism. Imagine screwing it down to the panel. Now imagine trying to screw down the opposite panel. Madness I tell ya!!!

Picture 3: Here you can see all of the layout I had to do to get this to work. The holes in the 4 corners of the "square" are for the monitor bolts (these are through holes). The holes on the diagonals that are inside of the monitor bolt holes are for mounting the lazy susan bearing. Finally, the large holes are for mounting the opposite panel to the lazy susan bearing. I had to go through the circle panel in order to attach anything to the other side.
Picture 4 and Picture 5: Here you can see the lazy susan mount actually screwed into place. The first pic shows it out of place and the second pic shows it in place where you can imagine coming through the large holes from the other side in order to secure it to the other panel.
As for the rotation of everything, it is quite good. Not much play and the rotation is smooth. I'm not going to be sure this will be the way to go until I mount the monitor and set it at the proper angle. That's about it for now. Once I find the right screws I'll take a short movie of it rotating so everyone can see how it works. It's a start! :cheers:
