In the following weeks,I will be making my 2nd tent.The first one turned out fine but I wanted to try and make one out of silnylon just for fun,keeps me from roaming the streets at night.
I decided to make an a-frame style tent,sort of.No crossing poles to fight with in the sleeves,in fact,no bent poles at all.
A few weeks ago a did a tour of Death Valley and one night I was so tired,seems like it took almost an hour to set my tent up,I almost crawled inside as is and just let it lay on top of me.
I make tents like I make race cars,I build a frame first that takes all of the abuse,then hang panels from that.
On the tent above,sleeves were made for the poles with flanges,to sew a felled seam too.
I considered the same thing for this tent,that's what most of the big companies do(not the sleeves but the felled seams),but after extensive testing at the Booger1 Laboratory,I have found that a lapped seam bonded together with 100% silicone,then sewn,is MUCH stronger than sewing alone.It's so strong,that the parent material fails before the seam.It's FAR stronger than a felled seam alone,no comparison.
Also a zig zag stitch in silnylon spreads the tension over more threads than a straight line of stitching,a stepped zig zag stitch is better yet.
The addition of bonding all seams will add about 3oz to the overall weight,well worth the extra strenght in my opinion.You could bond the tent together with silicone only but you have to watch your seams,shear strenght is enormous,peel strenght not so good..So with the addition of a line of stitching to prevent peeling,the seam is more than strong enough.
I have started already,and have some parts done.I didn't bring my camera to work but I will post some pics when I get home tonight.
The tent will be 5' x 7'------52" high in front,46" high in back.It will be a "hybrid" tent,meaning I will be seperated from the tent walls on most of the tent but not all.It doesn't have a seperate net tent inside.I will sleep crossways in the tent giving me 8 1/2feet of lenght on the bathtub floor,LOTS of room.
It seems big but the vestibule is inside with me,instead of on the outside.It just seems stupid to have all that wasted space on the outside.There will be some covered room on the outside for wet stuff.
According to my math,this tent should weight about 3lbs,maybe a few ounces over.That includes everything,poles,ground cloth,stakes,guyropes,bathtub floor.....everything.
You don't need fancy sewing machines,I made the tent above with a $25 dollar straight stitch machine from the second hand store.I upgraded to a Singer 328 zig zag for this tent because of the light materials,it was $35 from the second hand store.
So follow along if you wish,maybe visit the Goodwill near you and try your hand at making stuff,it's fun(most of the time)
