Built the basic, truncated octahedron's, for the model. CNC routing of MDF, assembled by hand with spruce strip edging.
​
I have ordered the square and triangular up-stands from Cut Laser Cut, too much to route and too dusty.

Looking good, will get the assembly with the up-stands complete and then epoxy tissue to seal.

After being given a load of 6mm think A5 sized MDF sheets I decided to cut the hex and squares to build a "fuel pod" at studio scale from the Valley Forge, Silent Running.

The cut edges are chamfered to a close edge and glued. On the inside I have taped and epoxied the joins, a strong basic geodesic box.

The raised edges are 1.5mm thick spruce, wood glued in place. The corners will need filler since I couldn't get another width to keep the same edge width on two sides. The square edges other hang to be sanded back and become a little thinner - I think this is as per the studio model but that is difficult to tell. The best referance comes from Lunadude and only a single referance dimension is shown.

I will skin with glass fibre tissue and epoxy, that will hide all sins, bits of filler and make a strong box that should resist delaminating or exposure to moisture / movement.
