Do the capstans generally throw smoke or dust in normal operation?
I've never had to mess with an anchor in canoes.
Kept a 3 tonne anchor on mine, you never know when a nor'easter might blow in.
I think most of that 'smoke' is rust. Probably not the best thing to be standing near if it blows into your eyes. Looking at these braking systems reminds me of how tiny the rotors seem to be on my 5,500 lb Jeep. When I pulled my wheels to replace the rear pads I was stunned they had about the same surface area as my little Veedub Folf runabout. Some day when there's money I'd like to upgrade all those rotors. I can only imagine the heat they experience when I'm descending about 4,000 feet on CA-190 into either Death Valley or the Panamint Valley. A lot of kinetic energy being converted into heat which must be dissipated.
Those chains, though, that's really something to watch go by. Big, heavy and build up some serious momentum.
