Making A Yurt Rafter Ring

One of the most basic components, yet one of the most crucial structural elements of any yurt is the rafter ring. This device holds each rafter in place, ensures geometrical and structural integrity of the building, allows for installation of the essential dome vent and must be installed so as to apply uniform weight and pressure to each rafter at the same time that each rafter equally holds it in place. There are a number of pieces that make up this assembly, whether it is designed and constructed in-house or custom ordered.

The ring, in some instances, is built from one piece of wood. However, this is quite a costly venture, relative to the total cost of the yurt. Other wooden rings use a layered approach, sandwiching a layer of OSB between pieces of dimensional lumber, or the reverse. Other rings are constructed from metal, or metal and wood combinations, while a few are built of polymers. Since most yurt-dwellers have a core of self-sufficiency, I recommend constructing the ring completely from dimensional lumber, in layers.

For this piece of your modern Mongolian yurt, you will need fourteen eight-foot lengths of one by six spruce, fir or pine planks. As well, one quart of carpenters glue and one hundred eighty two-inch construction screws complete your parts inventory. For tools, you will need a variable speed drill, � inch drill bit, screwdriver bit, jig saw with blades and a small paint brush.

Begin by cutting all of the eight-foot lengths of planking into four-foot lengths. Lay them side by side, using nine pieces on the first layer to form a near-square. Due to the actual width of a six inch plank (5.5 inches) he total width should be 49.5 inches - slightly wider than the length. At this point, this is not important. Next, tie these boards together temporarily, using one of the four-foot lengths screwed across the centre point of the nine boards. Apply a liberal coat of carpenters glue to the surface.
