John,
If you take the end of the rope, set it next to one end of the drum and run the rope sideways across the drum to the other side. Wrap duct tape around the drum (and line), now take the rest of the line and winch it in. You will want some pull on there to keep everything tight (and so when in use, the line doesn't duck underneath the line still on the drum). Call me if that doesn't make sense - 510-352-8781 Adam
