The files on the homemade cam were posted by Bill Rouse. They are a great design and I am sure work well, and certainly look great.
As a full time liveaboard, the option of machining teak really isn't available to me. Even if it was, my time is more valuable than the cost of the commercially available lever cams.
Of course there are others who would enjoy the process of making them from scratch, and not put a price on the time involved. They will end up with something more elegant than I have and I would not begrudge them such satisfaction for a second.
The commercial product is certainly not as nice a solution as the custom made teak cams, but are they are way better than the handwheels!
