I've built a few bows along with Dave's guidance, and use of his tools. (messed up a few as well). I now work a lot slower than Dave.
We have both tried talking folks into learning. I gotta say that building along with someone in the workshop seems to make things go faster, and I just like combining brainstorming ideas.
When we invite folks to build, most ask if we could just build one for them. I don't think thy understand what they are missing in the process in really understanding their bow. We tossed around the idea of building them and charging, and I'm glad Dave posted the question here. Glad to get so many responses and open our eyes to issues we hadn't considered.
Currently being assigned to a ship isn't going to leave me as much amateur bowyer time, but maybe I can get some of my crew into the workshop, as they are asking questions about my Traditional Bowyers Bibles.
Having made my first bow this past summer, and building more bows since with improving technique and experimentation has been addictive in it's own right. Then taking small game with a bow has been a new challenge that has brought a new level of satisfaction to the craft.
Seems like trade and tutelage are the most appropriate paths to take for this traditional hobby/sport. The comaradarie, the development of skills and craft and the trading of ideas are probably more valuable than the bows themselves.
