I almost decided to eliminate the springing hands because I couldnt figure out how to accomplish the effect. Im glad I stuck with it because really, the spring-loaded arms are the whole point of the project. They are what make it unique.
The solution came in two parts. 1) A spring from a ballpoint pen, and 2) 1/4" drip irrigation tubing. If I could make a point here, it is to never abandon your ideas. Sometimes it may take a while to figure out how to accomplish something, but in the world of woodworking, anything is possible. Just stick to your guns and solutions will come to you.
Same goes for designing projects themselves. Allow your imagination to lead you. The logistics will follow. Start with your right brain then let your left brain kick in.
Peace! Zenwoodworking guy is OUT!
