Bucket Indexer tips

We had exactly the same problems you described and spent two weeks of build season trying all kinds of methods to fix the jamming.
It came down to a simple thing for us....we cut a strip of 1/16" lexan and cut it like a comb. It is duct taped to our bucket where the frisbees leave.

It has enough force to hold it in place and flexible enough to have a piston push it through. The teeth will eventually break, but making 20 spares is easy.

We did something similar to this at NYC. We took a piece of flexible plastic that wasn't lexan and used it to essentially shim out our bucket to fit the frisbee better and prevent the discs from riding up onto each other. We are still having a few jamming issues and withheld our hopper to work on it so I'll post anything we come up with, hopefully this thread stays alive because I know this was a problem for a ton of teams at NYC.

You might be having the same problem we were. In driving around a lot, the bottom frisbee can occasionally move forward, causing the second frisbee to fall back, and thus making your piston hit the second frisbee instead of the one on top. I would recommend some sort of grip tape on the bottom of your hopper, so that the frisbee on the bottom of the stack has a hard time moving forward except with your piston hitting it. We were not able to fire in teleop in a large number of our matches, and after one piece of grip tape we shot fine, and put up 60 points of frisbees in teleop.

Unfortunately I don't have any pictures right now of our setup. But if your problem is the bottom frisbee sliding forward, grip tape works wonders.

Thanks for all the replys guys

Were going to try to pull the frisbee from the bottom lip instead of push it from the back. Theory being that the disks sitting improperly above would have no effect on this type of system, as long as the disk doesn't slide out of the bucket early by itself. We currently have a few strips of tape meaure we cut and taped to the inside of the bucket that act as our gate, and thats been working.

Will update.

[THE DYNAMO]

we discovered an easy solution to all of this: put a bolt or other kind of 'nub' on the inside of the bucket near the bottom. the 2nd frisbee will rest on this bolt and the bottom frisbee until the botomm one is ejected, at which point it will fall down and the cycle will repeat.
