Two cool projects. Drum brakes are cool. I ran them on my old winter commuter in the day. I was a 60's era Schwinn frame. Cooks Bros cranks, MTN bar and stem with the drums laced into modern 26" rims. Kept the old chrome fenders and OEM fork. It was a fun towny.

Its really not that hard. I love building them personally. Even back when I was building them a lot. About the only thing that sucks is 48 spoked BMX wheels. Just a lot of crossing to do there with not much space.
