This site is very graphic. We also use it for a 'beamer' presentation, that's why the pictures are so big and colorfull. Please be patient.

The pedal unit consists of three pedals, of which the clutch is rather unusual for a PC race system. This is mainly because there aren't many games that directly support a clutch pedal, so Thrustmaster, CH Products etc. wisely decided not to put a clutch pedal on their products, as they would only make them more expensive. These days however, there are some games where you can use a clutch pedal. (Grand Prix 2 and Grand Prix Legends for instance)

We're also working on a way to make the use of the clutch pedal nescessary, by disabling the gear-shift buttons until the clutch pedal is pressed. The idea is that without pressing the clutch pedal, you can't change gears. We will make this option switchable, so if you don't want to press the clutch all the time, you don't have to. Here's a rather nice AutoCAD solid/perspective/render thing: (i.e. this is how it's going to be)

The pedal unit might not look very 'realistic', but bear in mind that your average desk arrangement is quite different than a Nascar cockpit. We're going to make it comfortable for use underneath a desk, using a normal chair.

The gray bits are aluminium, fabricated using a CNC plasma cut machine. The green parts are 2mm thick steel sheets, bended 90 degrees. The red parts are cog-wheels, used to 'drive' the potentiometer. We've used a cog-wheel ratio of 4:1. The pedal only 'rotates' 30 degrees, and using this ratio, you get a 120 degree range on the potentiometer. Add some nuts and bolts, and you're just about finished.

Due to their center of rotation, the pedals don't move forward to much. This means that the heel of your foot will stay in one position, and it feels like the pedal is pressed downwards. This takes a bit of getting used to, but at the end of the day, it's very comfortable. (you don't want your feet to slide about while driving 200Mph)

Up next are the drawings for the green and grey parts, showing all the dimensions you need. Take a look at the picture when you get confused.

You're going to need 3 pieces from the parts above. For the wooden enclosure, we've used 18mm MDF. Check out the picture at the top of this page to get an idea of it's dimensions. It's a bit fiddly to put all the parts together, but it worked for us. For pedals, we've made 35mm round 'rollers', with a length of 50mm, out of NYLON.

To give the pedals resistance, we've used rotation springs. (for want of a better term) They can be tricky to get, but we've managed to find a small 'spring factory' kind enough to supply us with 3 of those springs. Confused? maybe the drawing below will shed some light on the situation:
