I was messing around in CAD class and came up with this. Nothing revolutionary, just what i think is a well designed pedal. I have not worked on the spindle or bearings yet but that will be next. Oh and the body is about 78g out of 6061

 

[AlmostHeaven]

nice! looks pretty solid and nicely designed.


cue the whining b!tchfest about how much they weigh innnn 5, 4, 3, 2,...

 

[RUFUS]

Those things look like a tank.




JK, very well done, that is a great looking pedal.

how bout addin some screw holes to the center X member?

looks nice and simple. i likey

 

[Prettym1k3]

No screw holes in the middle, but I'd take an added few grams if you could concave the middle a little.

I think that pins in the center will put pressure on the wrong parts of you foot and could be painful.

The Spindle i will make at my work because that is easy part tooling and machining wise.

I would remove one of the screw holes on the f/r cluster of holes, and spacing them accordingly. IMO it would allow the shoe to sink onto the pins easier, sorta like how you can stand on a bed of nails, but cant stand on one or two. Just my thoughts. other than that I think it looks wicked.

The next step is to go and get some quotes from local machine shops. Then we will see if they get made. The Spindle i will make at my work because that is easy.

OK, I held off on criticism since I figured you were a young'n and modeling those just as an exercise.

I would recommend that you take step back and engineer the spindle and bearing system first since that is the major constraint which will govern your pedal design.

Secondly, you are going to want to design that pedal body as a manufacturable part. As it sits now, you are looking at a part that will require a good bit of fixturing and rotating in a 3-axis machine. You probably will also get some grief or laughs from the machinist since you don't have any corner radii which is governed by the tool size. Whenever designing something it is a good idea to use some basic DFM&A principles to minimize cost. Since you want to make this as a machined part you really should pay attention to things like the number of times it needs to be flipped/setup, and the types of tools necessary to mill out the features. As simple as that pedal looks you may besurprised at some of the quotes you get back.

Anyway, good luck, but start working on RevB

That's exactly what I was thinking. You could make it but it would cost a lot. I can't imagine EDM'ing a pedal just to get tight radii. I was taught to solid model using the exact same method that you would machine it. For instance, how would you core it out? I guess you could start with an extrusion but i don't know if that would give you the mechanical properties that you are looking for.

Good modeling though. It's not as easy as MS paint.

 

[beaverbiker]

add some tiny radii in all the internal sharp corners. that will help with the manufacturing.

 

[bfrich]

these pedals work well for us and would be a less expensive alternative - but i give you props for thinking about it:

Very Very good advice!!

 

[NY_Star]

I think that you are all missing the point, this was something that i drew up as an idea, I know that this model is far from production, I do have experience in a machine shop and know what you are saying for tooling radius and how many times the part must be set-up and the tolling changes that must happen.

 

[Scurry]

I feel like you might want some structure under the main set screw areas, connecting the top plate to the bottom. I had bad luck with pedals that spanned that distance withough anything connecting to the bottom.

but what do i know, im just an arsty architecture student haha
