A while back I posted a question about calculating saw angles for making a tetrahedron from square stock. It took a while to solve the problem, but I was finally able to make what I was after:

Just curious, why did you taper off the corners? Break too easily?
Would you care to share the calculations that you came up with?
Pretty interesting.

The corners aren't actually tapered, they form those angles when beveled to fit with the other two pieces. A line from one corner to any other corner lies on the surface of the 2x4 chord of the joist, so the corners aren't tapered or rounded off in any way.

The cuts were made at 35 1/4 degrees, with the saw tilted 30 degrees. I cut from both sides, which forms the point at each end of the joist. The interesting thing is that with those angles, a 90 degree angle is formed on the surface at each end. You can see the three 90's at each intersection.
On the old ones, the pieces come to a point. On the new one, they are beveled.
Help me understand this. :-)

Those were both made with sticks that are square in cross section. The one with the sharp points has the sticks rotated 45 degrees from the where they are in the 'beveled' one.
