Using a garage creeper as a mobile platform for a racing simulator.

Basic - intermediate woodworking skills recommended.

Items required:
1x Garage creeper ($15 - 50)
1x gaming system ($100 - 250)
1x Steering wheel/pedal set ($50 - 250)
1x Car seat (Free - $50)
1x old computer monitor ($50 - 150) (optional)
Various Scrap Wood, screws, cables, etc.

Tools required
Table saw
Drill & Bits
Basic hand tools
Paint & brushes (Optional)

Step 1: Out With the Old

Do you see the problem?
It was an eyesore and ergonomic nightmare.
This was version 1.0: the workbench racer.

Step 2: Sourcing an Appropriate Chassis

Look around the house for some found objects.
In my case, it was a garage creeper I hardly used.
(You can easily create a mobile platform/chasis by slapping some casters and 2x4's up.)
Head to your local junkyard for a cheap ol bucket seat.

Here, I'm laying out the parts needed.
There are 2 screws on the bottom of the creeper to remove the cushioned surface.

Step 3: Building Seat Mounts

Since the dimension of components will be different for every build. (ie: Seat, creeper, game system, monitor, wheel/pedal setup)
Use this write up as a general building guide, then measure out required mounting points for your components.

Create seat mounts by fixing scrap 2x4's onto the creeper's chassis.

Step 4: Mounting the Seat

Here's the seat mounted using wood screws.

Upon leaning back into the seat, there was a potential of flipping over backwards,
so I installed a small wheelie bar using some spare skateboard wheels.

Step 5: Building the Base

Measure and cut two 2x4's and mount them onto the creeper chassis.
(This will be what you mount everything to so be sure it's secure)
They should encompass the pedal set as shown.
I have also added a wooden platform between the 2x4's.

Step 6: Framework

Build framework around the pedal set using scrap 2x4's.

Step 7: Test Fit

Quick test fit, always be testing to see whether it fits you.
In most cases your bucket seat will have adjustments in all directions.

The chrome tube supporting the steering column is an old hand rail.
The steering wheel is mounted to a platform that telescopes back and forth on a 2x4 via a set screw and wing nut.

Step 8: Painted and Ready to Go

Here's an overall shot of everything painted.

I have also added a monitor riser made by some more scrap 2x4s.

Step 9: Detail: Steering Column

Here is a close up of how the bar supporst the steering column.
For the monitor, you can either build a platform for your monitor to rest on.
I continued the 2x4 theme and built a raised stand.
