Looks like a turret plate?

It does look like a turret plate.

I looks custom made, what kind of material is it?

From the picture it looks like wood.

It's definitely plywood, not sure what type or grade though.

It's clearly not a functional part for the robot, and seems to be some sort of statue or sculpture of an angry god.

I think I know exactly what part that hole pattern goes to...

they might be planning on epoxying it.

I'm guessing this is the wood prototype before the metal version for the final bot is made. :)

Does this part mount anywhere near the 14 lb. shooter wheel ???? ;)

im guessing plywood prototype of a turret , made on a waterjet at GKN. Im guessing the real part will be aluminum, and at least 3/8 thick(probably 1/2inch)...:D :D :D

False, True, True, False

We set a record at the GKN waterjet; the code to make the part was 3700 characters long and took nearly 2 hours to cut. The best part is that the part came out perfectly. No need to redesign or remachine here! :D

It's the plywood backing that was used to cut the 3/8 thick aluminum turret plate (a sprocket) on the GKN water jet.

The teeth look #25 pitch to me, wouldn't that make the aluminum plate 1/8"?

It looks more like a timing belt pulley (a really really big one!) than a chain sprocket, so 3/8" makes sense.

#25 chain

1/8 aluminum plate sprocket

204 teeth

Good catch Adam. You and Ryan are correct. 3/8 would be way too heavy!

You have us beat. We cut out a 180 tooth 25 series sprocket for our turret. Ours was done with a laser though.

The real test will be in the crater. See you in Atlanta!

Indeed. I hope we get to see you guys in Atlanta.

You have us beat too. We used a sawzall to cut the center hub and spokes out of a swamp cooler pulley

AND how to you plan to place the chamfer on the sprocket teeth?? I can think of some interesting solutions but am curious as to your plans...

.... or are you leaving them square and hoping for the best by keeping the chain tension "extra tight" since I assume this will lie in a horizontal plane....

GKN's largest lathe can handle 20" diameter parts, which is where we will be doing our work. If it really came down to it we could stick it up on our VTL we use for our 6ft diameter engine nozzles. :-)

Well, wouldn't be the first time 294 over engineered something.... lol

(i.e. last years "cheesing" of the upper A-frame)

:D :D :D

Very nice. We cut a 183 tooth timing pulley for our turret on a laser cutter out of quarter and eighth acrylic. Works very well.

We made our weight and it never broke! Good luck to the Greybots. See you in LA and Las Vegas.
