5" Wheels
 

I would like to be able to buy good 5" wheels, does anybody know of some?

Re: 5" Wheels
 

What was your reasoning behind choosing 5" wheels? Even number diameters are drastically more common. If this is for a FIRST bot, you'll have trouble finding wheels that you can mount easily, be it on live or dead shafts. I strongly suggest that if you need 5" wheels, you machine them yourself.

Re: 5" Wheels
 

Well I prefer smaller wheels, but my design wont allow for 4" wheels. I am aware of the relative scarcity of odd numbered wheels but I'm wondering if delphi knows any good sources.

Re: 5" Wheels
 

Colson wheels are good, albeit lower traction.

What's the application?

Re: 5" Wheels
 

These wheels are pretty awful, and likely not usable for any design which requires live wheels, but try anyways: http://www.amazon.com/Fairbanks-905-.../dp/B0026GFQZA

On further research, it seems that Banebots wheels come in a 4 7/8" size, which I'm assuming will work for your design.

However, I warn that they're a pain to mount. That being said, they're fantastic wheels. Their driving surface is among my favorites.

Good Luck!

Re: 5" Wheels
 

That's the first positive review of a banebots wheel I've ever read (for driving).

I would recommend Colson Performa wheels, they come in 5" sizes but provide less traction.

However, I would also recommend you work with a chassis design that allows for regularly available wheel sizes instead of restricted to 5". What is requiring a 5" wheel?

Mcmaster sells some nitrile rubber wheels that are 5 inches, but they are very heavy.

unless you go down to 4 inches, i dont think there is much of a performance gain between cots 5 inch wheels and cots 6 inch wheels.

Re: 5" Wheels
 

Stogi and Adam-

Are you sure about the Colsons having less traction than a wedgetop/roughtop??


A member of our team did a ton of wheel traction testing as part of his capstone project...the results may surprise you guys.

Also during matches they tend to heat up. Making the rubber sticky and more traction. They also wear down pretty evenly.

Re: 5" Wheels
 

WOAH! 5 inch wheels???!!! It's like the compactness of a 4 inch wheel, and the largeness of a 6 inch wheel! Amazing!

I googled 5 inch wheels, and found some good results.

Re: 5" Wheels
 

If you're looking for a more customized wheel to suit your needs, and you have any crude lathing or milling abilities, you could consider making your own out of stock aluminum. Then you can make the diameter whatever you want, as well as customize other features like lightening pattern and how it fastens to sprockets and/or shafts.

Obviously, you should CAD the thing first, keeping in mind the limitations of whatever shop tools you have. Then, the actual machining process would be an excellent exercise for any student. We really need to give our students more jobs like this; they somehow can't ever drill a hole in the right spot, let alone mill something to spec.

Sorry if that was too unrelated to your inquest about buying wheels, but its an option that, while usually not as practical, shouldn't be totally ignored.

Re: 5" Wheels
 

Where can these results be found?

Re: 5" Wheels
 

That's very interesting, I'd like to see the results.

Re: 5" Wheels
 

Let me get the results from our teammate, and I'll publish them and repost with the location.

Re: 5" Wheels
 

Has this happened?

Re: 5" Wheels
 

I too am interested. And, I'll throw in another vote for the Colsons, although they are a little heavy.

Re: 5" Wheels
 

Embarrassingly no. We have a meeting tonight- hopefully I'll have time to pull the data off the computer while I'm there.

Colson rubber wheels heat up o.O

So what you're saying is that our robots should be doing side swerves in autonomous, like NASCAR racers do on pace laps? :ahh:

Re: 5" Wheels
 

Might be able to get away with spinning in circles for a few seconds at the end of auton.

The crowd always likes that. :D

Re: 5" Wheels
 

Thanks. November is almost upon us, so it's time for my annual "what wheels might we want to consider" internal monologue.

Re: 5" Wheels
 

COLSONS solve all problems. Done...no more internal monologuing
