Are they gripper parts? It looks like a pulley with a hex broach and something else with a hex broach

That's no pulley! (I cannot confirm or deny that I am watching star wars)

I assume I'm ineligible for this...

Isn't anything robotics related cool?

A double sprocket before the teeth are hobbed, and the cylinder is likely a wheel hub to be press/cast into a plastic wheel.

No, it is a system for keeping the Fro fluffy.

Dang it.

You're right, though I hoped that it'd take a little longer to figure out.

The part on the left is a blank for a 22T double sprocket, made from 7075 Aluminum. It's been broached before the sprocket cutting to make things a little easier for the mill operator.

The part on the right is a 'plug' for a 2" wide colson wheel, made from 6061 AL. Preliminary testing shows that the press is good to at least 80 foot-pounds of torque.

(I'll have to bug you on FB for a shipping address once the stickers are made.)

I'm pretty sure that the smaller item could be part of a cable winch. Could the larger item be an adapter from a hex shaft to a different type of shaft?

EDIT: Dangit, I was both late and wrong.

Oh I see where you're going with this one Dustin. The topic that we were discussing about makes sense then.

...Or just give them to me for hand delivery dude. We don't live that far away.

If you guys can wait until Madera I can hand deliver them as long as they go next to the "Powered by..." sticker on your bot ;)

Drain plug to keep the water out and a small anchor???

I've been making a variation of the press-fit Colson hub since 05 using the same principle. If I'm seeing the hub correctly, it looks like its knurled which is something I've had great success with as well.

Looking good.

For season I see the resources used to make the double sprockets better used elsewhere, and instead just purchase off the shelf sprockets.

Why do I get the feeling there is going to be a heck of a good time had at Madera?
