Thanks melev...I understand the need for the notches but I was more refering to how the two ends being glued together stay along the same line without angling slightly...I guess I would have to draw a picture. But what I am getting out of this is that the square can actually hold up your end piece without falling over and creating a mess????? I can just envision the end piece leaning up against the square, pulling the pins, and then watch as the whole thing falls either right or left in on itself...guess that isn't as big of a concern.

Your tools page shows guitar strings. Are you on to those now or are you on the acupunture pins? Have you found anywhere else online that sells the pins without requiring a $25 order? The local acrylic tank manufacturer uses fishing line...ever tried that?
