Hexayurt project/Hexayurt H13 Plywood: Difference between revisions

H13 Plywood

• Vinay Gupta invented the basic shape in 2003. The H13 was designed by Scott Davis and Dylan Toymaker (design published in November 2010). The H13 adds one panel to the “classic” H12 hexayurt, but that one extra sheet of plywood gets an 8′ roof line and 2-3 times the walkable space inside the hexayurt.
• The H13 has been built with polyiso panels and there's even a design to make it folding.
• This page describes the specificities for a H13 built with wood.

Before you start

Tools

• You need to cut 5 diagonals and XXX blocks. You need to do some trimming.
• You need to screw XXX about 200

Wood

• 13 panels of plywood or OSB3. Each is 4" by 8".

Screws

2" deck screws. Any head is fine. Non-countersinking screws are better because they don't weaken the plywood wood where the screw is by crushing it or cutting into it. XXX number.

"Wafer head" seems to be the name for these. But I've never found them locally, so I use regular deck screws!

Cost

Naming the pieces

• A "panel" cut through the diagonal gives us 2 "triangles". Please refer to this chart to name the "panels" and "triangles". (By the way, you can use this chart to print it on paper, then cut and fold it, and just cello-tape the walls (1a to 2a to 3a to 3b to 2b to 1b to 1a).

• The "wall" has 6 "wall sides": 1a, 2a, 3a, 1b, 2b and 3b. Each has a small triangle cut off. The triangle is a rectangle triangle: measure 6 inches for each leg of the triangle, then cut through the hypothenuse. This is called the Sri Lankan corner, because it was invented in Sri Lanka (V has the details).
• The "wall sides" are joined together with 12 wooden blocks, 2 at each angle, which are made from 2"x4" wood, cut at a 120º angle.
• The "roof" has 2 "classic roof sides" (4a+5a and 4b+5b), 2 "big roof sides" (6a+7a and 6b+7b), and 2 "horizontal-vertical roof sides" (8a+9a and 8b+9b).
• There will be "blocks", cut off 2"x4" lumber: some are cut at 120º angle, others at 150º angle and others are used "flat". The following pictures shows MOST of the blocks right. Still looking at the video (above) to find out if some are wrong! Sorry, no high visual skills! LucasG 08:38, 27 July 2011 (PDT)
