You know a "Gauge", well since there so big. I mean a Plug. Wood ones. I am making some in Wood shop for my boyfriend. they are 2 inches and they are quit easy to make. So what if I made those all semester and sold them? [not 2 inch ones, i can make different sizes.] Could I do that? How much should I charge? I wont be putting any finish on them bc that could cause problems. just wood plugs. My friend has some, they are fine.
