Truck bed liner?
That sounds interesting.
Please keep us posted as to how that turns out (pics too)

Great job on the circle cuttin'

Two steps forward, one step back!
So I've mounted the monitor, got the software rotation/wiring working at 75% completion, when a few things happen:
1. I've realized that the weight of the 21.3" monitor is putting too much stress on the 5/8" area used as the rotation fulcrum (main bolt). The pan has about 1/2" wobble, and this time, not around the bolt through the wood mount, but across the bolt head/pan intersection. This is causing too much pressure being applied on the motor wheel, which in turn, causes the motor to struggle to the point of almost not being able to rotate in one direction, and needed a gentle push in the other direction. A stronger motor might solve this, but at the same time, so would a redesign of how all the pieces fit together. It makes me kinda grumpy to even think about redoing the mount, but it's not been a real joy mounting the cross brace by yourself. So that will be one consideration in the rebuild. Also, the spacing between the multiple bezels, I'd prefer to see mounted to the cross brace instead of the monitor anyways. AND.. i feel the cross brace even when mounted with three screws on both sides of the cab, sill had a bit too much twisting capabilities. I think next brace will be more "shelf" like. Also to note, the umbilical cord of wires coming from marquee light, power buttons, and sound cords interfere with bezel removal. More things to consider..
2. While messing with trying to relieve the motor strain, I ended up tearing off one of those flimsy soldering mounts on the end of the hobby motor. That's the second one that's happened to, so I have no spares. Time to hit Hobby Lobby.
So right now:
1. Everything is mounted, but will have to come out and be redesigned.
2. A new motor will need to be purchased, or I'm going to have to see if parts are sold to fix my specific issue.
3. Pulse modulation software still hasn't been proven to work in my rig yet, but using the "always on" config settings I proved communication with Mala using the Advanced Wiring 2 schematic in Weeisupts PDF. We're discussing things over PM, but until the rig is fixed I'm back at square 1.
There it is folks. Avoid the pizza pan :)

Too bad it didn't work out. It looked sturdy enough.
Personally I gave up the whole idea of having a rotating monitor.

WOW csa3d!!! Unbelievably awesome job - nice and clean and GREAT documentation. Too bad you ran into some trouble - I'm sure you will work it out. I've been out of the loop with my project but I have all weekend starting tonight to push forward! Hopefully I'll get somewhere.... :cheers:

Any updates? I'm very interested in this as I'm trying to decide on a cab and may redo a similarly designed one (completely gutted with no CP though)
