First functional prototype (a modified C2 Model D) which utilizes gravity instead of an elastic cord to take up the chain and return the handle. At this stage all of the geometry had not been worked out, which accounts for my truncated stroke. It was nevertheless a satisfactory proof of concept. A more refined prototype is demonstrated in the video "Gravity Return Dynamic Rowing Ergometer" on this channel.
