I've been meaning to post pictures of the tipi. First - I'd like to thank everyone on this forum, specifically Ben. Thanks for the design ideas. I ended up building a mockup in google sketchup, then scaling the tipi to the size I wanted. I did not use cat curves, and decided on an octagon footprint. I'd have to go back and look at the dimensions in the sketchup rendering but I think the tent came out to be around 7 foot tall and a 13 foot base. I could be a bit off there.
I honestly think I would have went home early on my week long backcountry hunting trip without this tent. The weather was s@*t. We made a small homemade stove with pipe for the tent, and the whole system worked great. One day it snowed like a banshee and my partner had to hike out - I was able to dry my clothes, eat a warm dinner and listen to a baseball game on a portable radio through the storm. It was really nice. The tent came out weighing a bit above 2lbs total.
I think when I build another (oh, I will) I'll keep the design the same with the exception of taking the zipper to the peak. I think you could zip this thing all the way open, tie it off and have a pretty decent shade shelter for the lake/beach. Since there's no floor, this thing is also going to get some ice fishing time this winter with the stove. The sky is the limit! Thanks everybody - just one last thing... if you are considering doing something like this - just go for it. It's the only way to learn.
Next up - backpack, or quilt, or another tent!
