I wanted to have a generic surface for mounting various switches and different permutations of gauges and data loggers, so I built a dashboard by shaping it from a flat sheet of aluminum. I thought it would only take a day, but it took a bit longer. Given that this is only my second attempt at metal shaping, the result is surprisingly good and it ways next to nothing. Take a flat sheet of aluminum and start pounding the crap out of it until its the right shape… (I may be oversimplifying a bit here) then weld the corners.
Here’s a big project that spread out over a number of months. I’m aggregated the photos here and attempted to make them tell a coherent story.
The cluster as a whole can be adjusted forward and back for drivers of different heights. The gas pedal is adjustable for foot travel, throttle cable travel and left/right position. The brake pedal height is independently adjustable, and brake bias is adjustable from front to back. The hydraulic clutch pedal is also independently adjustable for height.
Many of the original pieces were laser cut from steel, then bent and welded to form the complex shapes required. Some of the bushings were CNC turned, but most were made by hand. The master cylinders, brake bias adjustment cable, and the nuts and bolts were purchased, with everything else custom made. This includes the brake bias adjustment assembly, which forced me to learn how to cut threads on the lathe. It’s not as easy as it looks. Take a look at the brake bias adjustment bar– it has three sets of threads independently cut on a manual lathe, three diameters, two snap rings and a threaded hole. Good fun! Due to changes in the steering rack mount, the main pedal bracket had to be widened as you can see in the photos.
I looked through a bunch of street car transmission shifter cables, brought a couple of them back to the lab, and decided on one that was the correct length, light, and low friction. Everything else was fabricated…
The car will use a Suzuki GSX-R1000 engine, which has a 6-speed sequential transmission, meaning the shifter only has two movements: shift up, and shift down.
