Why no pics of your favorite wheels teams?

If you are using a dead axle how are teams interfacing sprockets with Colson wheels and other designs that seem intended or designed to roll un-powered?

Ask and you shall receive. Attached below is an image of FRC2168’s custom aluminum hubs to adapt the 4”x1.5” Colson Performa wheels to the “standard” AndyMark bolt pattern with tapped 10-32 holes. They are a press fit hub. This design allows us to utilize 3/8” dead axles (grade 8 bolts).

We had zero failures thus far and have not changed the wheels since build season. We fully intend to improve on this initial design to reduce some machine time and run Colson wheels next year if they work in our design/strategy.

Feel free to ask more questions.

Our hubs were literally the same exact thing and we've had just as good results. Through 2 regionals (both of which playing through the 3rd match of Finals), IRI, and a couple of additional off-seasons, we haven't had to touch our drive train.

We are planning for a release near Thanksgiving.

Ya I can't wait that long.

REGOLITH!

Why? you knucklehead!, you might ask. Well, it was my first year on my schools team, and our programmer managed to get our 85 lbs (regestered) to shove around full-weight bots with the trailer at right agles to their desirred movement. :yikes: :D

Last year we got the replacement wheels for AM 8" mecano wheels, then made our own torch/bend aluminum faces for a whole lot less! The only issue was programming/wiring...... Plugged in declarations for Vics instead of Jags, and the whole thing went all wick-wacky at low speeds, but high speeds were just right.....:o

You could probably drill those bigger to save some weight. All you need is a little step to hold the outer race of the bearings. Overall they look good though. Do you knurl them?

Or you could just use flanged bearings. :)

Chris has an inside scoop I guess. The newer design does in fact use flanged bearings, a quick look at my blog will show you some of the stuff we've been working on.

Last years hubs were not knurled, and I don't think we'll knurl them in the future either and none of them spun, to my knowledge.

Question: When people refer to colson wheels, which type are you referring to? I was trying to see if we wanted to use colsons this year, and couldn't figure out which kind of caster we would want.
