We had good success with Delrin hubs in our shooter wheels this year. Went with around 0.004" over size press, some may have been more like 6 >_>. We have a big arbor press and I may have gotten a little carried away with the interference #SorryNotSorry.

Much lower durometer than Colson wheels, but not as compliant as the teardrop rollers from McMaster. Prices range from $2.50-$5.00ea (not counting hubs, which are only necessary for applications other than 0.500hex). 4 durometer options and numerous size options.

(CAD coming soon on the website--we were too excited to let these sit on the shelf.)

Hope that you will have enough stock of all four of the wheels.

Beyond the 2" sizing, this one has a black color option too!

Keeping stock for plastic molded AndyMark products is not a problem. Our mold shop is about 5 miles away, and they provide fast service. We don't have to keep gobs in stock, due to quick production runs.

We may run out of stock for a molded item for a few days, but it's always back in stock soon.

This is reason #3480 we don't buy molded parts from distant lands.

Sincerely,
Andy B.

Fun fact, at size 12 single spaced Times New Roman with 1 inch margins, you can get ~46 lines on a page so the AndyMark handbook for buying molded parts must be at least 76 pages assuming each reason is at least a single line.

I'm guessing Andy uses that handbook to keep his desk level.

Also, the entire AndyMark employee handbook is only 15 pages. (I just checked.) Aside from FIRST's game manuals, I can't think of any company-guiding documentation that comes in at 50+ pages.

Also, you think Baker can't build a level desk?

LOL. Now people are going to be looking at that desk for teasers.

Baker can't use you to defend his honor! He better provide a video using a NavX to show how level that desk is without a stack of paperwork under those wheels!

Marshall, don't spit into the wind. Even I can cut and drill pieces off site for an outdoor workbench to be used from a boardwalk and have it come out level at the right altitude (and be more solid than the boardwalk). Baker's so got an indoor desk that it's not funny.

That desk has wheels and is clearly meant to be rolled outdoors into the rain. #WaterGameConfirmed

At this point I'm just trying to see how absurd I can make this thread prior to kickoff. I'm waiting on Nate to drop a memey gif in here next.

We are rating the 2 inch wheels at 6000 RPM, or "don't go any faster than direct drive off a Mini CIM" below that speed it will not significantly expand (~1mm) but above that speed it becomes unstable and different parts expand at different rates. Interestingly, even at ludicrous speeds (+10,000 RPM) the hex will stay aligned if nothing touches it. When subjected to hard impacts at any speed the hex will slip (game piece, compression, and RPM dependent) but for the application it is designed for, that isn't really a problem. Even if it were used as an FTC shooter wheel for this years game it would probably function pretty well since the balls are light and only have to go a few feet. I can also say with confidence that it will not explode below 6000 RPM. I am unable to do any damage to it by hand, and it took putting pins between the spokes and stretching it by mechanical means so that the pins were over 13 inches apart before it tore.

Also, they are back in stock, so BUY BUY BUY!

Or one of our even newer 4" compliant wheels rated to Over 9000 RPM
Also an expansion vs RPM table should be up on the site soon (along with more stock )

That number seems DANGEROUSLY high to tell general case to team's at large.

With compression and a high number of shots, I'd be very concerned running at that number.
