Huge thanks for that, but I'm with you on the principal of ownership, even if there's no formal protection. As an engineer, it's a simple common sense design, but it has flaws. There's too little thread length to ensure it keeps in tune. I have a way around that, & I've already consulted with my builder on making an enhanced version. BTW, the builder I'm partnering with on this unique drum project is Dean of Guru Drumworks. Maybe you know him? Great guy. These lugs are probably the most standard bit of this kit build, & are only being applied to the kick & snare. Thanks again, Andy.
