where did you guys get those wheels?
Custom 5 inch wheels: 2 pieces of 1/2 lexan cut out on our CNC. We cut designed patterns to save weight and make them look good 
These are the new version of our wheel from last year. http://www.chiefdelphi.com/media/photos/26365
According to the caption, they’re custom. Probably from the CNC in the back.
edit: Shan beat me to it
I’m liking the nitrile tread, wonder who gave them that idea?
I think 116 gave us that idea, but the one idea we won’t be taking from 116 is how to destroy the Smithsonian’s floor with nitrile tread 
If by destroy you mean leave pretty blue artistic loops on a concrete floor of a construction area, then sure. :rolleyes:
Nice work Shan and Ash. I am liking the extruded
That’s the messiest floor I’ve ever seen on ChiefDelphi.
where can you buy nitrile tread?
McMaster-Carr caries it. It’s under “incline conveyor belts”.
how fast you guys moving this year?
we are geared for 11 fps under no load
2 cims and kit transmission then we are geared down with a belt and pulley drive system - 612 doesnt do chains
