Re: Constructing a simple Two Drum Winch .

Nice job!

Another option that removes the requirement to machine is to use AM hex hubs. Use an extended or 'long' shaft on your gear box and slide your hubs on.

Keep in mind that your wire / rope on the drums may not build up or release at the same rate as the diameter changes (if it overlaps itself on the drum). Many teams use a tension spring on the pull-down side to account for any inequalities between the drums.
