Aluminum Gas Pedal
 
5 Attachment(s)
Hi Everyone,

I have always hated the plastic gas pedal and how it does not match the clutch or break pedal. Recently I have been working on replicating the clutch and break pedals, I figured I would post up my current progress to see what you guys thought of them, as well as if you had any ideas. I messaged GoodfellaFD3S before making this thread and he mentioned possibly making some wider pedals for heel and toe down shifting which I think is a great idea and I will make a prototype soon!

Anyways... here are the pictures of what ive been working on so far, hope you enjoy!

Originally I tried to 3d print a pedal, then use it as the pattern to cast a pedal from since the clutch and break are sand cast. Well my sand was much to rough and looked terrible, plus the sand picked up the line between the layers of plastic so that was a no go. I decided I would try machining one instead.

Here is the machined pedal fresh off the CNC before I sand blasted it.

I had some 'levers' waterjet cut.

Here is a comparison of the OEM pedal and the machined aluminum pedal.

And finally here is the pedal installed in the rx7.

Im excited to hear what you guys think!

Very nice. Think you'd get a fair amount of interest on a wider pedal.

Curious, is the stock spring sufficient for the heavier material.

Sideo 01-25-17 07:08 PM

Thanks TomU,

Ill get that wide prototype made ASAP. I haven't driven the car as my engine is out for a rebuild but between the spring on the pedal and the spring on the throttle body I didn't notice a difference.

Oh man. I'm in.

I would suggest drilling to match... and yeah, a wide option would be fantastic.

If you want a guinea pig - lemme know. :icon_tup:

Looks nice. I'm down to also be a rodent, along with Matt.

yea def awesome stuff make a dead pedal too if ya can :-)

hadokenny 01-25-17 10:15 PM

Very nice. I am very interested. Are you able to replicate the dimples and holes inside the circular rings as well?

cloud9 01-25-17 10:33 PM

Interested to see and learn more. Love this community.

As mentioned, a wide pedal option and a dead pedal would also be well received.

Would also see the hole alignment revisited. Looks like you were messing around with it. More uniform vs more dots would be my recommendation.

I'd love to see some of the holes drilled out like stock, the enterprising owner could probably do that themselves OK.

Attached some images of similar (but NLA) product for ideas and opinions.

I'm in for one of those :icon_tup:.

Thanks for all the great responses guys!

TomU:

I weighed the OEM and aluminum pedals this morning. OEM weighs 112g and the aluminum170g.

TomU, MattGold, hadokenny, Narfle:

I can definitely drill the pedal to match as well as add the 'dish' inside the rings. It looks like a half-inch ball endmill matches the contour pretty well. I modeled a wide pedal with the drilled holes and dished rings last night.

LoU "hOw Ya Do" and Narfle:

I think a matching dead pedal would be great. Definitely a lot more work but ill have to start working on one!

Absolutely awesome. I think you'll have a home run with either.

As for dead pedal, a full on replacement would be ideal, but that'll probably require a brake to fold the metal into form. Don't dismiss just a cover like the OEM accessory was:

Might be a way to short cut the process a tad.

MattGold 01-26-17 03:33 PM

...also 170 grams - but you haven't even drilled it out yet!

Last thing (I swear, if I could I would have edited these posts together).

Perhaps take a little width out of the top? I would have *slight* concerns over brake/gas mistakes.

I think where you want the width is lower anyhow, added benefit is that it maintains some of the factory look:

Heel toe, y'know?

Also, I'm not sayin'...but I'm just sayin'

Titanium.

TomU 01-26-17 06:47 PM

The raised circles match and look good, but wonder if they would snag on your foot.

Think this type of design might be more suitable (and probably saves some weight)

You may need some real world R&D to see how it works

But of course :nod:

Sideo 01-26-17 06:59 PM

Keep up the input! I agree that looks MUCH better. As I was modeling that pedal I thought " damn that looks like shit but I know everyone wants a wide pedal"

I will remodel this pedal and hopefully with everyones guidance we can figure this out!

This is my primary concern. I read a forum post that mazda made the pedal plastic and smooth to avoid this. Like I said I havent driven the car with it installed but playing "cruisin usa" in my garage this hasent been an issue. I would like to have a few people test them. Looks like I already have two volunteers in this thread :)

Sideo 01-26-17 07:05 PM

This is a good point! I DO have access to a break as well as a TIG welder so I could reproduce the whole dead pedal but it would be very time consuming/expensive. If a cover would be well recieved that would definitely be an option.

money ready ~ nice product sir

DC5Daniel 01-26-17 07:47 PM

Ready for some future FC options :). All our pedals are crappy plastic.

Sideo 01-26-17 07:49 PM

Ill remember that!
