I've barely had time to work over the past couple weeks, but I've finally got it mainly complete. Here's a few pictures of the process. Most everything went smoothly, except for my monitor setup - that's been a real pain in the neck. I ordered 3 Acer XB270HU monitors, as I got a great deal on them refurbished, and there are next to no options for 27" 144hz IPS panels with G Sync. One came with about 50 dead pixels, which was RMA'd. Then I found out there must be some sort of compatibility issue with iRacing, because all 3 of the monitors freeze up for about 1-2 seconds about every 30 seconds or so, making them completely unusable. So, back they go... I now have a single Curved 35" BenQ XR3501 on the way. It will have to do for the next couple years until some quality 144hz IPS panels come out. Anyway, on to the pictures.
I ordered all 97" lengths and cut myself. I was treated to two boxes weighing about 95lbs in my driveway, which was a real treat to move inside.
All cuts were made with a 12" mitre saw and a Freud Diablo 96 TPI non-ferrous metal blade. I was surprised at just how clean the cuts were. I didn't even really need to sand, but I scuffed the ends real quick with some 320 grit sandpaper, and I'd say the cuts were just as smooth, if not smoother than the factory cuts.
About 2 hours of cutting and sanding later, I'm left with a box full of my future sim rig. Everything was pretty straight forward with assembly. The sparco R100 mounted directly to the frame, but I did need to pick up shorter screws with a regular allen cap head. The pan head was too big to fit inside of the R100's sliding rails. Nothing a quick trip to the hardware store couldn't fix.
One minor nitpick was there was a tiny bit of play in the steering wheel. The wheel mount itself is rock solid, but the Thrustmaster TX only has 2 mounting holes, so there was some vertical wiggle. I lined the aluminum frame the steering wheel mounted to with rubber t-slot cover and that did the trick. Everything is nice and tight with no wiggle room, and I don't have to worry about the aluminum frame cutting into my wheel base.
I ordered 3 Bytecc 100x100mm vesa mounts. These have full tilt/swivel adjustment. One thing to note, is it was near impossible to tighten the tilt adjustment enough for it to hold the weight of the monitor. I replaced the plastic knob with a standard 6mm allen screw and tightened it that way. Not ideal, but for $20 a piece, I think it's more than worth it. I drilled out the mounting holes so that the standard screws/t nuts fit, allowing the bracket to mount directly to the aluminum frame.
And here she is in her near-completed glory. I've already removed the additional monitor arms, since I've decided to go with a single 35" screen for the time being. Someday they will be reattached... someday.
Sorry for such a long post. I'll try to make another post with the final plans, exact cut list, and all the parts I ended up using in case anyone is interested.
