Added door handling and simple locking mechanism.
Finished door including a door handle
Simple door closing/locking mechanism
Finally did the last thing, the door. I used some laths, with frame and insulated with Sagex. I assemble a simple door locking mechanism with wood next days.
Door construction: laths vertically
Complete door with hinge
Sagex in between for insulation
Door closeup: where the main wall/khana rope goes through
Door closeup: 3 roof poles lie on the door frame
The only thing left is the floor.
Sew the main cotton interior cover, 5 lanes: 6m, 7.3m, 7.5m, 7.3m and 6m again, each 1.5m width, apprx. 1cm overlayed to sew the lanes together. Took a lot of threat more than expected. Also attached cord each meter of the two 10m x 2m wall covers in order to bind them to the main wall rope, made seam for each ends.
I finished the toono cover with its clear PVC, it's a bit fragile to whole thing, next time need thicker wood for the frame. Sew three pieces of the PE rain cover together to 2m x 19.7m long piece. The cotton interior I will keep in sections, two pieces each 10m long, and attach some cords (like inlining of a tipi
) to the main rope, each 1m or so, makes 10 cords to attach each section.
Preparing clear PVC
Clear PVC cut-out, to form a cone
Roof cover frame segments
22.5° angle for 8 segment polygon frame
Reenforcement to screw segments together
Clear PVC patched, and laid over frame
Attaching clear PVC
Outer clear PVC layer attached
Two layers: one inside, and outside reaching over the frame
Attaching cord to fixate roof cover to roof
The pictures above are from the 2nd cover I made, since the first broke during stormy winds (flew away because I didn't tie it); when I made the first roof-cover I didn't document or photograph each step.
The last days I took down the yurt again, had to protect wood (crown-wheel / toono, its collar and door frame) from water using wood wax, but also wood lacquer, not yet sure which is better.
Today I sew the PE rain cover, from 8x10m -> 8x8m and 8x2m, and fixed the cut making a seam with a cord within. The 6x4m with one cut making 6x2m twice, also sew the seams with a cord.
I folded the 8x8m so the center appeared as corner (twice folded), then cut with scissors 2-3cm cut, this made 4-6cm hole, the center; as next step I put the crown-wheel / toono with its collar (where the clear PVC comes on) on the opened cover, and cut out the hole, had 4-6cm spare to the crown-wheel / toono collar. Finally sew along this hole with a strong cord, to have the canvas just fit the crown-wheel / toono and its collar.
Sewing the roof canvas/cover
Sewing in a cord into the seam
Roof cover and toono/crown-wheel
Cutting hole into roof cover
Final roof cover cut, 3-4cm left to the toono, sewing then a seam with cord
Sewing in the cord to the roof cover where it goes to the toono/crown-wheel
The floor wood is coming soon, yet, the floor insulation (Sagex) I have to wait for 10 days to get - so if all goes well October 26 I raise the yurt with all.
What's left to do: crown-wheel / toono cover (frame & clear PVC), cotton cover (lot to sew), door and the floor.
Finally complete erect the yurt with all roof poles (uni), test-wise to see if the poles, roof angle etc are matching my calculations before I cut the roof poles (just a few centimeters though).

Toono Symmetry - Beautiful!
Since I had two drilling diameters for the toono (two diameters of roof-poles since I used the smaller end of the bamboo sticks on the toono and bamboo sticks are sorted by thicker ends when you buy them - which meant I had to resort them, and we ended up with four different diameters: 2.0, 2.2, 2.4 and larger than 2.4 (those we took aside, just a few); I took the 2.0cm and 2.2cm diameters. I color-coded the roof poles and holes in the toono (2.0cm: green, 2.2cm: red) so when I put it up I see right away where which poles goes in.
Some angles are a bit off, e.g. wrong tilt, wrong angle, but due the length of the roof poles it didn't matter as much, the poles just bend a bit. I also didn't recalculate anything (unlike previously thought), but had the cord on the end of the roof-poles give more or less space as required as I couldn't compensate the unevenness of a 8-segment polygon vs. perfect circle with deeper holes in the toono - glad it worked out this way. So, the 8-segment toono was a good choice, just the segments and their end-angle of 22.5° needed exact cut - the resulting toono with 6 x 6cm profile looks filigree.
I calculated 2.88m roof pole length (6.4m diameter, 1.22m toono diameter, αroof 26°), the bamboo poles are 3.05m long, so plenty left. I assumed 2-3cm fitting into the toono, plus some extra as the cord at the end; so I just drilled the hole for the cord at 2.90m, which seems just right after I put up now all roof poles.
I also now realized after the first put up that the toono holes for the roof poles are short enough to support different angles, I had a bit little space and the diameter is less than 6.4m, apprx. 6.25-6.30m, and so the roof angle is a bit steeper. When I build it up again with exact 6.40m I assume the roof comes down a bit, good to know I can make 6.20-6.50m diameter - just one thing needs to be kept in mind: it needs to be a near perfect circle so the roof poles truly fit and are pressed unto the toono, no sloppyness allowed there.
The main rope on top of the khana I moved between the junctions (over a junction and next under the junction) all around, and then tightened it several times til the rope at strong tension, then I began to put up the other roof poles (started with 4 and then the rest).
Anyway, I'm impressed by its beauty in real life, the toono with its roof poles in it looks like a sun . . .
I'm a bit delayed with updating the diary. Haven't been working on the yurt each day, and also was a bit slow when I had to glue wood (waiting til a part has dried and then doing the next part etc). So here a few photos of the state currently with my yurt developement. Due to rainy weather I haven't been able to work on the yurt and do some required measurements of the toono plus roof poles.
Toono 8 segments
Putting together two segments
And so on ...
The toono finished, without roof pole holes, glued and tied with a rope to press together for 12 hours
64 roof pole holes into the toono, 16 per quarter, 24 = 16, means 4 times half the angle of 90°
90° divided by 16
Marking the position of the holes, for each toono quarter
First test of putting 3.05m long roof poles (need to cut to 2.88m) into the toono, diameter as expected (6.76m, with too long poles, finally should be 6.4m); holes with right tilt/angle drilled!
Putting up the toono-cover frame (plus clear PVC, not yet assembled)
- saw the segments for the toono (22.5°), glueing it together
- doing plan for angles for the roof-pole holes, drilling the holes with right tilt (26°) and angle - was hard since I had to do this by hand and drilling machine
- additional collar on top of the crown-wheel / toono, the rain cover will be pulled over it to have no rain reach the inside of the yurt
- crown-wheel / toono cover (clear PVC) frame (8 segment again), a bit larger than the crown-wheel / toono collar so it can be put inside of each other, the crown-wheel / toono-cover frame gives the form for the clear PVC (slightly tilted done using a cut)
The next days I sew the canvas and cut the roof-poles and attach some cords for the fixation to the khana. More pictures follow.
I bought 6cm square wood lath, 2.5m long, for the door but also for the crown-wheel / toono. A collegue saw the other lath for the 8 segment toono, but I also realized a small bug in my n-polygon calculator, and now I require to decide if the quite thin (6cm) 8 segment toono works, and may have to cut the roof poles individually (aside of the different diameters and required holes), which I wanted to avoid, more calculation required, but might be worth it.
The bamboo poles for the wall and roof arrived, and we are using black rubber binders and not drilling the holes, just on the top of the wall, the other holes are done via those binders. The first attempt was laying out the wall poles on the floor which turned out time consuming and not very efficient, the next khana section I did vertically which I did quite faster.
The bamboo sticks (made in China)
Drilling holes on the top, the rest of the "holes" using rubber binder as connectors
Closeup rubber binder
Two poles ("twins")
The rubber binder
Laying out the lattice wall
All the way
One finished khana section
Closeup khana, binding vertically - much easier
Adding twin poles individually
Finished khana, two sections, twice 30 1/2 total 61 junctions for poles, the door will be 3 poles wide
So, I decided the make the door 3 times w wide (3 roof poles), also 3 * 31.4cm, 94.2cm - so the khana carries 61 remaining roof poles, two khana section with 30 and 1/2 twin poles. Since I used bamboo two khana sections works, expanding apprx. 10m, but otherwise apprx. 70cm wide when compressed.
We also had to sort the roof-poles, since we decided to use the thicker ends on the khana and the thinner ends into the crown-wheel / toono, and there holes need to be drilled - so I got two diameter sizes of roof poles / uni, less than 2.0cm and less than 2.3cm.
After weeks of planing and calculating & taking notes
Melanie got the bamboo poles from a garden wholesale company I researched beforehand:
- 150 wall poles 2.12m, 20/22mm diameter the thicker ends
- 75 roof poles 3.05m, 26/28mm diameter the thicker ends
We require just 64 roof poles, but it was cheaper to get 150 poles (for two yurts) than buying the exact number. The cost per yurt for the poles apprx. CHF 200 or € 130, or US$ 160.
