New design that i did today. I made it so that both halves are symetrical so that it is easier to machine, (It only takes one program). The screws are 8-32 SHCS. Questions? Concerns? Comments?
Looks nice. Are you planning to broach the center with a hex or key? If so you might consider indexing the broach so that the “halves” broaches line up. This would allow the halves to be truly interchangeable.
Looks nice to me. Course… I’m not the mechanical genus… My questions are only about the CAD program. Which one are you using?
Also, do you think you could get away with fewer spokes?

I am using Solidworks 2009
Yes, i could but i liked the look of 10 versus 6 spokes for some reason.
Yes since my upload i have added the hex broach and the halves line up perfectly. The purpose was to have the halves be interchangeable.
Nice Wheel,
How much does it weigh with bolts?
-RC
0.42lbs With bolts
0.36lbs Without bolts
Is there any chance that you have the AM Shifter Gen 2 CADDED with the gear teeth? If you do can you send it to me?
Thanks RC
My my that looks mighty familiar. I too wonder about your plans for the bore, and the necessity for symmetrical halves. You might consider not having the bore extend through both halves. Timing/indexing a broach is a pain. Also, you may find it not worth it to have the wheel be two halves at all, if simplifying manufacturing is your goal.
Nice! looks kinda familiar! Haha =)

I see you’re going “clamp style” for tread, but you need a little groove along your rim that captures the tread so it doesn’t fall out (higher quality picture here where you can see the groove better http://604robotics.com/Blog/wp-content/uploads/2010/02/IMG_0296.jpg). I like how you made both halves symmetrical for ease of machining, however, what we do is make them asymmetrical so you can have a locating groove instead of using the screws/axle to center the two halves.
Also, you might be able to get away with less spokes. 7 is a cool number.
Keep up the great work!
Well i was thinking of broaching it while it was assembled or just simply keying it. The two halves is so that you can clamp the tread along with rivits for a better grip.
Ah,
I would try to aim for about ~.3 lbs. How thick and wide are those spokes?
Yes I do have one, when I get home tomorrow I’ll make sure to put it up on the CAD Library.

Yeah I agree. As you can see from the pictures I posted, the back of our wheel is just a rim, which saves weight. It simplifies the broaching issue too. By the way, those 6" wheels I posted were 0.28 pounds each.
Each half has a 1/8 spoke thickness and a 1/4 combined thickness.
The spokes are 1/4 in wide each.
Thanks again RC
WOW thats light!
The CAD says it is .28 pounds, but when I weighed one it was .23 pounds.
Psh, 604 needs to bring these babies back.

There’s really no point to making a two piece wheel without having the undercut groove to capture the tread. It won’t be any different than a one piece wheel without it.
Yeah i know ive added it since i just forgot to do it when i took that picture. Thanks Cory
Someone explain to me why, in this day and age, anyone would bother making custom wheels.
Because they’re cool! Although I have to say AM Performance wheels are really good, especially their price. You could get custom wheels about 40% lighter though. If that matters.
