The FabHouse is a ShopBot-capable version of the Hexayurt. It is constructed as a pressfit assembly.

Plans

The sides of the house are made from six 4x8 sheets and have 13 cuts each. On the left side, four slots, 6" high each, on the right, five cuts makes for four locks that go into the slots. This is enough to make a hexagon of six 4x8s.

On the top of each side there are four slots, 18" each, which serve as receptacles for the roof pieces.

The roof is constructed from six 4x8 sheets. To start off you need to cut along the diagonal a jigsaw-like shape. In cutting this, you may leave out 4" from the middle, as this is the amount by which the sides shortened, minus 2" that we'll use later. At the shortest end of the two triangles you now have, you cut tabs that fit into the receptacle slots on the sides.

Finally, on the longer of the two shorter ends of the triangles, you cut alternating dovetails, 1" deep. These dovetails serve to merge the ends together so that the roof is rigid.

Now, patch the jigsaw bits together and apply some adhesive. Next, lower the roof pieces one by one into place, fitting them to each other on the dovetail edges.

Chimney edition

When preparing the triangles, leave a 2.5" long cut off the corner end of each one where the longer short end meets the hypotenuse, and make the flat end into half of a 0.5" deep tab. Then, when you assemble the roof, you'll have six 0.5" tabs jutting out into a hole in the roof. Now, make three 6" long boards and three 8" long boards that fit the gap, each with a slot near the bottom for the tab, and construct a hexagon chimney.

Before assembling, cut locking tabs into the three 8" boards. Now make a 8" diameter hexagon with slots for the locking tabs that can be placed on top of the chimney, to stop rain from entering. That way you have three 1.75" holes on the top to let smoke out.

Please consider that for cooking fires you might want to make the chimney out of inflammable materials and lengthen the chimney to reach down to the fire.

Waterproofing / Weatherproofing

Paint the plywood and tape over intersections.

Benches & Tables for the inside

The PlayaPew has been drawn up for use in the FabHouse as using 16mm thick fiberboard. Designs available for shopbot cuts.
