I remembered that you asked for the link on the Old Wakeworld site for the specs those kids posted about building your own winch...I bookmarked Wakeworlds site and not the actual URL...Do you have it by chance?
i built my own winch, and i have a list of all the parts i bought online and the sites i found them the cheapest. if you want it, along with some more basic instruction. fire me an email, ill be happy to send it your way.
