How much would the material and grommets cost for something like this?

[Fl0und3rz]

$5-6/yard for a 60" roll depending on source for silnylon, also depending on weight of the fabric.

That 12'x12' so at least 4 yards, maybe more to get the full 12' transverse dimension (the two side panels across and sewn to the main 50" x 12' section). 

You can get uncoated, also, and treat with silicone, yourself, for even cheaper.

That polyester is a bit cheaper most places. The grommets are cheap. I personally have found that grommets are nice but webbing sewn into loops are easier to work with and less likely to fail. So, material, thread, Cordura nylon for the corners. Maybe $70 for the material.

[Jonathan_S]

That tarp is pretty heavy though. I don't see a need to use that heavy of a material for a tarp. That thing weighs more than twice as much as a tarp I just made

Wouldn't it be at least 10 yards?  I'm a numbers guy but I know that when talking sewing there's some weird math that goes on, kind of like our federal tax code.

[Fl0und3rz]

If ran the seam down the center - kelty didn't - you'd need approximately 8 yards for 2 12'x60" panels.

In 4 yards of a 60" roll, you'd get one center panel, 12 ' long x 60" wide, then you'd have 4 45 degree offcuts. I'd have to layout those cuts to see if you can add any of them to the 60" dimension to get close to a 12' x 12'.

Otherwise, you would need at least 8 yards if you don't put the seam down the middle. But the total depends on your layout and how much use you can of "offcuts."

Linear yards. In this case = 36"x60" not 36"x36"

And FL0und3rz, most of the 60" stuff comes out to 58" because of the selvedge and open edge. Not a huge deal but it is a difference

[Fl0und3rz]

Thanks.  That's good info to have at the noodling stage.

[Jonathan_S]

Thanks.  That's good info to have at the noodling stage.

That's why we have smart guys like you and BULLBLASTER as engineers because you have a noodling phase. 

[Fl0und3rz]

Yeah, point taken.  I need to get out of the noodling phase.  Thinking about ordering some SS shim stock to start on a packable wood stove.

[luvmystang67]

Okay, speaking of noodling...

I'm having a tough time here.  Is there any reason you WOULDNT do SilPoly instead of SilNylon?

Anyone?  It kind of seems like a no brainer?  Is the SilPoly harder to seam seal or sew or something?

[7mmfan]

From what I've been told, SilPoly is a little less tear resistant and its tensile strength is a little lower than SilNylon. Also slightly more prone to punctures.

Yeah like he said, it's less forgiving to sharp sticks and doesn't have as much strength. These things aren't big deals to me, I can obviously patch anything and I don't camp in wind tunnels. Silpoly HS better UV resistance which IS a big deal to me.

[7mmfan]

The UV resistance is good to know. If you don't beat up your gear, that will add years to the longevity of your shelter. Jonathan, this winter I'm going to talk with you again and I'm going to build one like we talked about on the phone a while back, like the Badger Hole Supreme.  I'll need a refresher from you at that time and hopefully you can give me some tips that you've learned along the way   

[Jonathan_S]

Yeah the crazy thing is, even a Kifaru will eventually succumb to the sun.
