Help with pyramid apex on 03/18/2009 17:56:06 MDT Print View

I am going to make a 10x10x6 pyramid. I am pretty good to go on most of the seams/assembly. But, I am having a hard time deciding how to made the apex where the pole goes.

As far as I can tell the basic pyramid will stop short of the top. Then some reinforced material is sewed on (like cordura) and a silnylon cap over that to make it waterproof.

Am I heading in the right direction? How do I make the 4 sides of the cordura come together at the peak with the silnylon over it? I am stumped!


Thanks for any advice!

what i have done...

cut the sil pieces so they go all the way to the top. Sew the reinforcement pieces on top of the sil pieces(fold over raw edges). So each side has 2 sil pieces and 1 reinforcement piece that covers it. Then all for sides get sewn together. After sewing each side on finish the felling of the seam and then do the next side.

The reinforcement is done once each panel is sewn together before it is sewn to the adjacent one.

I am not very good at explaining things, hope this helps.

Ben,
Here is a link to were you can find a photo of the center apex section I used on my mid built using grossgrain material ... If I remember correctly.

Just another idea. Also, you might check out MLD's site as I think Ron has a few photos showing what his apex looks like. His designs and shelters are always top notch !!!

SO, I sew each side together and to get 4 triangle panels, then I sew reinforcement at the top of each triangle. Do I make the reinforment the same size as the panels at this point? Then I sew the "corner" side together to bring all 4 sides together.

What do I do when I get to the very tip. how so I sew the tips of the 4 panels together at the top? DO I just sort of bunch them up at the tip?

Thanks for the tips!

Does anyone have a picture they could post that shows this?
