more awsomeness from across the disctrict! Looks like both of our teams are busy w/ summer projects!

Love the engraved 114 on it. excellent looking design too. Has anyone dones stress analysis on it? you saw what happened to 1280's wheels in finals this year, and while these may be more easily replacable, you don't want to have the situation in the first place. Also, how're you holding the treading on? machine screws?

Why the 4 holes?

I'm thinking so that they have an option between using a live axle or attaching a sprocket to the wheel...

Thanks for the feedback!

The tread is held on by pop rivets through holes drilled into the wheel. The tread in question is roughtop from mcmaster, the blue thick kind. It's never done us wrong!

The 4 holes are for holding a sprocket to the wheel.

[edit] This is the wheel for the Coaxial swerve drive that is currently under design. If anyone feels interested in that, I'd be glad to spam our ideas/pictures/CAD files at you over aim. [/edit]

That tread looks great.

Do you have the McMaster-Carr part number?

Thanks

It looks like Nitrile based "rough top" incline conveyor belting on page 1125 of McMaster's online catalog. Here's the part number for the 4" wide unit 5994K852. This stuff held up amazingly well on the 2003 wire-mesh ramps.
