Thanks, Frederick. For years I would stop what I was doing to make a set for someone. It had honestly never occurred to me to sell them because the way I see it, it's just a triangle with holes in it. For guys who build model aircraft, they're easier to make than what they'll build with them. But it seems they just wanted to get on with building their planes and not mess with making tools. I still have a regular job though. The job pays the bills and the fixtures pay for my toys. Life is good.
