This is my interpretation of a Self Contained Racing Cockpit.

You will notice the design influences from Chilicoke's DIY cockpit. The simplicity of his design coupled with the real car feel that it appeared to provide is what made me say, “I must have one of those”.

That being said, I also wanted a self contained unit that was easy to move around. It had to be easy to get in and out of. The general construction costs had to be on the cheap and I wanted it to be something that anyone with a chop saw, skill saw, drill gun and some lumber could easily screw together.

Here are some pictures of the finished product:

Equipment used in this project:

-Logitech G27 Racing Wheel
-Logitech X 540 multimedia speaker system
-Hannspree 23'' Widescreen LCD 1080p
-Summit Racing Sport Seat w/Levers

I used Google SketchUp to design the cockpit. Once I had it looking pretty good and the measurements made sense I went out to the garage and cut all the lumber for the basic frame in one shot. I assembled the basic frame and made sure the seat rails matched up and that the dash placement was good.

Next I was stuck waiting for the G27 to arrive. Once I received it I immediately pulled apart the pedals to built the pedal rack and double checked my measurements assuring the shifter would fit in the center console. The pedal rack is just a rectangle as wide as the front dash supports and tall enough to center the threaded ends of the pedals. Both items were built out of 1.5X1.5 square lumber and the inserts for the console were built from .75" plywood. The pedals were test fit using C clamps to make sure the position was perfect before they were bolted in place.

Getting the whole thing wired up was a little tough in the sense that I didn't want wires all over the place ruining the clean look of the cockpit. I was able to run all wires down the right side dash support and under the frame in a 1.5" wire loom. I created a space underneath the spot for the PS3 putting most of the mess 'under the hood'. Also (not pictured) the subwoofer that contains amplification for the rest of the speakers is mounted under the seat (you can see the shelf for the sub in one picture below).

Few notes: The monitor mount was from my weight bench. It was the part that held the elbow rest and I never used it. It was hanging in my garage and I saw it out of the corner of my eye and thought, "No way that is 45 degrees". The dead pedal was cut out of some thin steel and mounted with 2 cylindrical plastic washers on some 1.5" wood cut to match the shape of the Logitech pedals. The wheels are 3-Inch 150-Pound Swivel Double Lock Rubber Plate Casters from Amazon.

So that’s my ride. Any questions, comments, things I could have done differently?

I know that DIY is not for everyone but if you are even thinking about giving it a try and have some basic wood working skills you can take a shot at this project for the cost of a few 2X4s.

I'll also include my Google SketchUp plans. Install Google SketchUp if you don't already have it and you can measure every aspect of this project and even edit some stuff if you wish.

Straightforward design with a very nice finish and well thought through details. Looks very neat! Thanks for sharing!
 
Very nice job! Looks comfortable and solid!
Is the chair adjustable (up-down, forward-backward)?
(Unfortunately voluminous for my small playroom)
 
Great build Wayside, good clean look too. 👍

BTW. What's the switch box under the shifter? Volume??
 
Is the chair adjustable (up-down, forward-backward)?

The chair is on sliders so it is about as adjustable as the average car seat, forward-backward. It is set to fit me in the neutral position (5’10”). All the way forward a 5’3” person was able to clutch, no problem.

BTW. What's the switch box under the shifter? Volume??

Yeah, the control pod for the speaker system. Volume, bass, power and a headphone jack. I wanted the headphone jack close so the cord wouldn’t get in the way.

I also have an extra 3.5” cable wired in for an external sound source. With the music turned off in GT5P you can pick your own tunes which is great.
 
Thanks guys.

Maybe worth considering adding a sub for added bass?

Sub is mounted under the seat. It's pretty much concealed but you can see the shelf for it in the pic where the rig is on its side.

Update: Momo Steering Wheel 4/4/10

Added a 350mm Tuner Steering Wheel. The adaptor is made from a 1/2" sheet of Plexiglass. Using a 3 1/8" hole saw I drilled a hole in the sheet of Plexi and used the portion it removed (approx a 3"X1/2" disc) to create the adaptor. No rocket science in drilling the holes, used the wheel to mark out the Momo holes and the Logitech center cap to mark out the hub holes. Marked them with a fine point Sharpie and drilled them with appropriately sized drill bits, countersinking the Logitech hub bolts with a second drill bit to fit the screw heads. The screws holding the wheel in place are coarse thread drywall screws. First I used the screws to slowly tap the holes, then I cut them very short and screwed the wheel in place.

Loving the full size wheel and the PCB view.

This is, without a doubt, very nice.

May I suggest three things though:
1) Bigger TV, mounted lower.
I've found 32 inches from about that far away is near perfect. Close enough that you can see everything, and the edges of the screen are viewed with your peripheral vision for an "added speed" effect. And, surprisingly, it doesn't strain your eyes nearly as much as you would think, provided you keep the backlight down. With a 23 incher, it's hard to imagine that it would be an "immersive" experience, considering you see so much else around it. By the added size, you could probably use the same TV mount and still have it low enough.

2) Cover up the gaping hole in the steering wheel!
Cool for a second, then -whoosh-. Fun's gone. Wouldn't be that hard to whip out a hot glue gun. Wouldn't affect anything else other than the hole.

3) Surround sound. Even with the good speakers, it would certainly be better if you could hook up extras in the places below. Shouldn't be hard to find a compact, low power 7.1 amplifier. You'd have 6.1, but it's good enough.

I'll never have the privilege to build this (or perhaps I will, we'll see!), but that's just what I would do if I did. Thanks.

Not sure what you're referring to... I don't see a hole in the steering wheel :P

Would definitely go for a bigger TV though. They are cheap now adays, even though you spent most of your money on that cool cockpit :D

You can get quality 32" HDTV for $500 or under pretty easily if you know where to look.
 
Ah the "sub" is below the seat, okay though it it must be tiny, if you call that I sub I wont argue with ya, lol.
This may be decent for the budget. In relation to the cost of the new wheel it seems audio has been skimped a little on is all. Youd def get benifits from something a bit more powerfull in audio terms.

Question:
Do like the new wheel, although not fussed on the PCB look tbh. With the full sized wheel is it now too difficult to reach the paddles?
Or have you removed them completely?

Upgrading Issues?
One problem you have with your design is if you now add a bigger screen like some suggested it wont be centred to the seat but to the actual frame. This would maybe then be odd if offset from the seating position. If you do centre it to the seat then its going to be sticking out the left side. Also noticed your screen seems up very high as well but maybe your quite tall.

Your cockpit looks great Wayside and I'm sure it's a lot of fun to use. I'm also sure 99% of the people in this forum would love to have it, whether they are capable of building one like it or not.
 
is the wood 2X4" or is it 1,5"x3,5" as it is in 3d model?

It has something to do with the way they produce the lumber. When the board is first cut from the log it is 2X4 but after it is dried and planed the finished size is 1.5x3.5

Thank you for that Stroker.

How did you join 45 degree angle wood to frame? I mean did you drill like half way so that you do not have use so long screws?
 
Wayside any way I could get the dimensions for your pedal rack??

Sure, the pedal rack is 31" X 8 3/4".

How did you join 45 degree angle wood to frame? I mean did you drill like half way so that you do not have use so long screws?

Correct, this picture shows exactly what you are referring to.

The two holes that you see are where the screws that go into the deeper side of the 45 degree angle of the wood reside, counter sink was about 2". The one screw that you can see goes into the shallow side of the back support, the front support is screwed in from the top on the shallow end as not to cross the screws that connect the base to the front beam.
 
Hi wayside, what a fantastic setup. My DIY skills amount to zero but my brother is a 'Chippy' so I'm get him to build it for me. I am new to this forum so that may be the reason why I can't open your plans attachment. Is there something I need to do from within this forum to download it. Winzip will not recognise it. I downloaded google sketch v7.

Thanks for the kind words.

I tried to download the file and it said the zip was empty?

Try this, same file but just pushed up today:

I just want to say I really like your setup wayside. I'm using it as a good starting point for mine. I'm wondering how did you attach the ply on the armrest where the black is, and is the black paint or fabric? Also how sturdy is it? And do you have more pictures on how the shifter attaches?

Again, great setup!
