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

or for people on budgets you could buy this....

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.

You roll your eyes, but it's been done.

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

Now why didn't I see this a week ago? Haha oh well, can't get it right all the time, at least it works right?

[Aren_Hill]

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

Guess what I found at Sears on Sunday:

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

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
