i'm fairly handy with wood, have built some plain and simple furniture and a kayak or two of wood and have a couple of nice tools, nothing really fancy, table saw, router, drills, sanders, that sort of thing. but after starting a couple of fuselages, i see that wood is very sensitive to the quality of the glued joints, which i don't really know about until i put them under load, at which point they fail somewhere, usually catastrophically. this is why i don't talk much about building airplanes lately. i wonder if aluminum tube and gusset would be more appropriate for an ultralight? i've never done much with aluminum tube, but am competent with a hacksaw (or a powered equivalent), drill press and pop rivet gun. would it be difficult to pick up the necessary skills to consistently bend and join tube? what about special tools?
