Playing with pinned joints

omni_dilettante · July 30, 2018, 12:46am

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.

Nice work, clever 4-way joinery.

Where did you get the giant penny for scale

Wow that is incredibly small!! Your fingers must be much more dextrous than my are nowadays.

Great job!

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:
