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.
