X - you bet, just stack two of the n3s pairs together and call it a mtmmtm.. ha. No, the reason I have not done the N3 towers is that you have to load the stuffing and No Rez prior to sealing them up. I have not found an easier way to make these unless I was to have all the other materials on hand, which is to much to invest. I have thought about making them and letting one side loose, but then it does not make for a perfect joining when the consumer would glue it up, i always router after the glue, better edge. So you can see the issue, I would love to try these for others, but the logistics does not seem cost effective for producer or consumer. I though Ruben was trying to put together a system of interlocking parts and the end user would just need a few clamps to finish. Not sure where he is on that. It would be very good for the end user non wood working consumer though.. Ruben. get going on this..
Sorry CX
