Playing with pinned joints

Spent some time experimenting with some wedged through tenon joints.

Everything was done with 3mm MDF, 200/full.

I started with larger components. I found the most rigid joint was where I had a wedge on each side of the joint.

Then I tried progressively smaller ones.

This was the joint I was working toward. Two pieces into another piece. Or four pieces coming together.

I decided to try and make a sphere.

My sphere attempt produced a large number of pieces that did not result in a sphere. So I tried to make a free form sculpture.

Recreated and made the obligatory dodecahedron:

I played with pegged joints a while back and made my pegs actual wedge shapes. It helped lock the pieces in position while still allowing for disassembly. You can see them in the second picture here:
