It looked like a bushing to me.

We actually cut a bunch of samples over the summer in .025" increments to test this size, and found that .425" flat-to-flat is the right number for this specific profile and material combination. This number would change for a harder or thicker material, as well as a part with less holes in it.

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!

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.

I have similar concerns about the wheel slipping on the hex at high speeds but I think a pair of plates will keep the rubber from expanding near the hex.

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.

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

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.
