Super easy to use.
We used a ratcheting wrench for our climber in 2016 and loved it. Simple, cheap, and already interfaces with a hex shaft. The reversible ones let you unspool the winch easily too. If we need a ratchet in the future, a wrench will likely be involved.

I like seeing all of the winch systems that teams come up with, but they tend to be a bit overkill. Winches that have a large reduction from the motor, but also a large diameter spool have always bugged me. The one in the OP doesn't have the large spool problem, it looks like a nice lightweight winch pulley.


For the milling operation pictured, is there a reason you're using a plywood support piece instead of just bolting the pulley to the table? We're getting more involved with milling, just looking for tricks we don't know about.
