My Guess, The rubber bands are for an anti back-drive mechanism.

You are missing one of the gears, so you obviously don't plan on using the shifting half. But why do that is the question...

EDIT: I just noticed that the other gear has been switched to something else as well. I'm going to go with Adam Bochek, an anti back-drive mechanism. Which would be great for hanging...

I'm guessing you're using the dog gears from the super shifters for a ratcheting kicker mechanism? That doesn't look like something I'd want to sit in front of for too long.

I just have to say that I really love gears, and super shifters have a lot of gears. It looks awesome.

By the way, I was looking into the exact same thing on McMaster last night.

Are those ratchets and pawls from McMaster?

Re: pic: 1678 Teaser #1

The McMaster ones run a little pricey. We bought 3 sets of the 3" ratchets and pawls for each. Its about 50 per ratchet and 40 or so per pawl.

And the ratchets happen to be 3/8" thick, which works out petty well

cut it in half and hold the handle solid

Ding ding ding! And David is the winner!

So, I am guessing you using these for a hanging winch or some sort. But why two? I have absolutely no idea.

Thankfully, they sell a lot of winches that has ratchets built into it, so we don't need to use ratchets and pawls in our gearbox.

Re: pic: 1678 Teaser #1

I was rolling my eyes over the idea of spending that much for a ratchet and pawl system that most likely took more work to implement.

And i know its been done, we've done it

its right on the end of that cable winch

Re: pic: 1678 Teaser #1

i'm just being cheap, you guys got a slick implementation going.
Im still wondering why you need two though....main guess is kicker and winch using the same winch construction

This guy is going on our robot this year (at least, I hope so).

Now now, no need to rub it in Ken...

And we'd need two 3/8" wrenches, just incase you're feeling generous

Re: pic: 1678 Teaser #1

Looks like a winch gearbox for kicker. The ratchet and paw are a nice touch. I used one on our leadscrew lifting arm to stop it from back driving as well.

Overdrive is using a very similar setup. Be careful with the stock shifting block and shaft they tend to destory themselves or explode.

I'll keep an eye on it. We have been kicking for a few weeks with no problems, and we have to use a 2" bore cylinder to pull the dog out
