Thanks for posting the video Mike, I found it really interesting and learned a lot. Just a quick question about how you fix the connectors. Did you thread the holes in the connector, or put nuts on the inside? The potential problem I see with using nuts is they won’t tighten down flat against the inner surface. Or did you use threaded inserts?
This is outstanding, have you thought about entering it into art shows as mixed media art? I have found some success in doing that with acrylic pieces held together with nut and bolts with straps made from veneer.
