Nice pics. Yeah I didn't even think about using threaded studs, and I used to install hardwood handrails for a living. (In which you use such bits of hardware) It would be trivial to add that but the question is how big do people want, what sort of hardware do people have available? I guess I'll just throw a 3mm hole in the middles and if one need it to be bigger they can drill it out or mod the sketchup. Thanks for the idea.
