Bender's Bjurts - Documentation - Dimensions

So, you want to build a bjurt.

The first thing to do is to figure out how much bjurt you can handle.

For the time being, I am concentrating on the octagonal bjurt. Since the cross poles and roof poles are the same length, this gives the most floor space for a given storage length. A folded octagonal bjurt has a width and depth of less than two feet each, and a length near (within an inch or two) of its roof pole length. The bjurt can also be broken down into its component pieces for long-term storage.

The following table describes the dimensional characteristics of different sized bjurts:

Octagonal Bjurt Dimensions
Nominal Size
Recommended Pole Material
Cross / Roof Pole Length
Brace Length / Wall Size
Inner Diameter (wall to wall)
Outer Diameter
Center Height
Finished Frame Part Number
Comments
10'
1/2" EMT Conduit
5' 10 3/4"
4" 1 1/4"
9' 7"
10' 4"
7' 10"
none
This size is useful because a single cross pole and brace can be cut from a single piece of 10' stock, allowing a bjurt to be made from 24 pieces of 10' EMT.
12'
1/2" EMT Conduit
7' 2"
5'
11' 9"
12' 9"
9' 3"
7128
This size is useful because two braces can be cut from a single piece of 10' stock, allowing a bjurt to be made from 32 pieces of 10' EMT.
13'
3/4" EMT Conduit
8'
5' 7"
13' 2"
14' 3"
10' 3"
none
This is the largest octagonal bjurt that can be made with 8' stock. The connectors are designed to accommodate 2" x 2" wooden studs, but this material has not been tested.
17'
3/4" EMT Conduit
10'
7'
16' 7"
18'
12' 6"
7178
This is the largest octagonal bjurt that can be made with 10' stock.

Mail me (link at bottom of page) if you would like to make a size not listed here. We can discuss dimensions and materials.

Once you have selected your size, you will need to procure your pole stock. The following table describes the amount and type of material you will need.

Octagonal Bjurt Pole Stock Requirements
Nominal Size
Number
Recommended Pole Material
10'
24
1/2" x 10' EMT Conduit
12'
32
1/2" x 10' EMT Conduit
13'
40
3/4" x 10' EMT Conduit
17'
40
3/4" x 10' EMT Conduit

Once you have procured your pole stock, cut it to the lengths indicated in the dimensions table. This will result in 16 cross poles, 8 roof poles, and 16 braces (8 horizontal and 8 vertical). At the time of this writing, 1/2" x 10' EMT conduit is available from Home Depot for approximately $2, and 3/4" x 10' EMT is available for approximately $4 (SoCal prices).

Congratulations! You now have a stack of poles. Time to drill them.
