I was thinking about sewing an 8 sided tipi for winter snowshoeing.
Probably a total length of ~9.5ft and height of ~6.25ft tall.
This would make each of the 8 side panels aproximately 4ft by 8ft.
The theoretical total weight of fabric would be around 19oz... who knows how much it would weigh with all the trappings. I would guess 25oz with peak reinforcement, webbing for tie outs, and seam sealing.
My justification for 8 sided is better wind resistance than a pyramid and I think it will take snowloading better.
When I look at pictures of megalights, supermids, ultramids, etc... it seems like the fabric collapses in between the mid edge stake and the corners causing more snow to accumulate. I figure I will get a little bit less of this effect with 8 sides. Now, I realize that I will still get some of the same effect but I think it should be lessened due to being able to tension all the stake properly instead of worrying about staking out the midpanels too tight. I also figure I can put more tension on all 8 stakes and will get a stronger pitch.
I like the idea of 8 sides over the 6 sided shangri-la approach since I think the shangri-la isn't as idiot proof. I find it difficult to balance the staking tension and location. With the octagon I ca stake a square, tension, stake the second square, and then tension.
Anyone think of a reason not to do it.... besided the fact that it will suck to sew 71ft of felled seams?
