I have been doing some work modeling the door frame for the yurt. It is 8 pieces and I will eventually have to decide whether I want to use dowels (or steel pins) or screws. The size that I have chosen is 4 khar mod spacings, or 51." The total height is 54.5 inches. This means that you'll have to bend over to enter. The first frame shows the door installed around some segments of the khana. I probably am missing something, because I had to manually insert a cutting plane to trim the lengths of the khar mod.

This frame shows where the khana segments fit into the door frame. I have highlighted the place where they fit in red. In real, rather than CAD'd yurts, there are groves cut out for them to fit -- An excuse to get a 3/4 router bit! As you can see, it is not the best of fits. I am sure that they can be persuaded to fit in the grooves. The youtube videos that I have seen indicate that this fiddly bit is not the easiest part of the assembly.

This last frame is an exploded view of the pieces of the door frame -- the total thickness is 4", so there will be room to install the door inside the frame, with maximum dimensions of 50" high by47" wide (minus hinges and door thickness).

I guess that I need to mock it up in cardboard for a better view, but this is pretty much a fixed/no wiggle room allowed set of dimensions.

You might want to click the exploded drawing to get a better idea of the way they fit together. The four upright boards are 1" by 3" and the 2 upright supports are 2" by 2".

Chao!
