i like you bill and much appreciate your participation around here even if for your own gain, but come on...felony...the plans are only ~$15 and you don't even own the i.p. on front loaded horns or any of their designs, so i'm not sure what legal ground you are standing on. in a legal sense, what you have is like a recipe for chocolate cake. a good recipe, to be sure, but a felony for sharing with a neighbor...no way. also, there is an exclusion for non-commercial use for patents, but you don't even have any. take your threats elsewhere. let's chalk this one up to bad weather and get back to being friendly. i like reading your posts and sharing thoughts.
