It looked like a bushing to me.
Just a thought,

Sorry to revive a dead-ish thread, but over the holidays I'm training some new programmers with a kitbot we assembled before the break. I am happy to report that these do fit on .5" hex shafts very well, and without much effort!

Did you get to actually try it out on an intake? And thanks for this. I'll try and twist my team's arm and get them to buy some of these.

I didn't. I don't actually have any hex shaft stock in my house (I live in an unusual household). That being said, I do have a couple of creative ideas using what I have on hand. I'll see if my programmers and I can whip something up when we meet.

Is the overall width on that 1/2 or 1"? Thanks!

This is my guess.

Yes, I measured it at 1/2" thick.

And OBTW, you can dummy a 1/2" hex shaft with some 5/16" nuts and a bolt.

Downloaded the model last night and it was 1". Layout drawing and site say 1/2". Just wanted to verify with someone who has one. Thanks again.

I'm out at the moment, but if memory serves correctly, it was thinner than 1". I'll double check when I'm home.

There's no way this wheel is going to work well at 5000 rpm. You wouldn't even want to use it as a shooter wheel. It's too compliant and it will buckle (that is if it doesn't explode).

Stick with the McMaster wheels if you want a nice compliant shooter wheel that isn't going to deform like crazy/explode on you.

Ok, so does anyone have any recommendations for shooter wheels that aren't $30 each? Are Colsons the best cheap alternative?

We used 4" kop wheels last year on our shooter, were only $6.00 each if I remember right

Any tips on how to adapt them for hex shaft?

I think the bore is 1", in the past we just made an aluminum hub that was .001 or so oversize and just pressed it in. You can probably take a colson hub or versahub and shave it down to size if you don't want to make a hub from scratch.

At a certain point you'll have to spend some money with some game objects.

Colsons worked for us in 2016, but in many other years didn't work nearly as well as more expensive options.

Considering the base price per axis in terms of speed control and motor, $30 per wheel really isn't that bad.
