Having watched our machinist toil at making her hubs for the past week or so, let me just say, superlative! Very nice finish...

What stock did this start as?

What diameter and width are they?

What stock did this start as?

Looks like either 6 or 8 inch 6061.

This all started as 8x8 square stock (hard to believe, eh?)

We had it CNC'd at our sponsor's machine shop.

Each wheel is 6 inch diameter, with 1.5" wide tread. They turned out so perfect that when you ding them together, the spokes act as tuning forks, and the chime lasts for a couple minutes.

I'm going to have to mar them a bit, the whole tuning fork effect is starting to give me a headache... :p

How thick are the spokes? (thick meaning in the Z direction on the CNC machine on which they were milled)

The spokes are .3" thick

This all started as 8x8 square stock (hard to believe, eh?)

We had it CNC'd at our sponsor's machine shop.

Each wheel is 6 inch diameter, with 1.5" wide tread.
The wheels started out of 6"x6"x1.5" thick Aluminum 6061 bar stock and the wheels are 6 inch diameter, with 1.25" wide tread.
This is a movie of the wheel being machined on the CNC (10MB Quicktime movie). (http://engineer.la.mvla.net/robotics/inventor/2006/2006%20Wheels%20%20Being%20CNC.MOV)

wow i would be square being pushed around by those monster wheels.

FIRST should have a "Best Bling" Award for the best looking parts or something, those wheels are so awesome.

those look awesome. what kind of tread is going on them?

At what feed rate is that mill running? We run ours so much slower than that, but we also don't pour buckets of water onto our parts, so.

They look very nice you did a good job, but how about weight?

Bah we always say we're going to use this one type of wheels and end up with the 4 they give us...
