old school throttle pedal extensions.

[keith]

I'm working through the bits we're making for our client's Mary Stuart RSR project, and I'm on the cabin stuff now; today I took a look at the throttle pedal extension from my reference photos:



- and I'm thinking this is wood, painted black (probably laminated plywood and drilled by hand?) - anyone have any direct knowledge about these 'motorsport' extensions from back in the day?

Like everything else, I'll make a few extra, so I'd like to at least get the material right...

not to hijack the thread, but that hub extension is something else !!

yeah, 74 steering wheel dissected! - lots of neat 'racer quality' bits on this car.

Ya gotta love the leather key pouch in a race car,,,,and without a floorboard how did they do the clutch and throttle stops? As to the pedal extension,,,,think 50 ft. rule. What would be close at hand, floorboard material, probably doubled up for thickness.

[keith]

I was thinking similar; materials at hand (might be what happened to the floorboard, perhaps?)

Laminated plywood makes much more sense than a chunk of wood for this, even if make hastily in the pits...

I would worry about the lack of a floor board.

If the throttle pedal over travels the side of the pedal box bends - only 1 mm thick- and the rod that connects the pedal to the reverse link sticks into the tunnel and then the throttle jams open.

I have seen this happen on two cars being used without pedal boards.

Very exciting and best avoided.

There isn't a part listed for this extension in either the 2.8 or 3.0 RSR Parts Lists.

I love wood extensions.

There are two things to consider.

1. Get the extension wide enough that it's up next to the brake pedal.

2. You want the accelerator pedal at the same height as a depressed brake pedal.

If you do both of these things you can then use the right side of your foot for heel & toe. Remember you're going to blip the throttle with the brake pedal totally depressed.

If you could wait a little, a friend of mine will see R7 (certainly the car in picture) in the future. I could ask him to have a look at this pedal extension.

Indeed, R7.

I'd LOVE that (and inspection of several other details.) In fact, I'd love to see the car in person; will it be displayed publicly?

I quite agree; but for this project, I need to reproduce what's on the MSRSR.
That being said, just getting the pedal height up relative to the depressed brake pedal will improve things quite a bit.
