double ledge info

Since the double ledge is a goner, no longer in production and abandoned, and IMHO the best combination of size to compactness/weight, here's some info if you want to build your own.  Expect to spend at least $300 for time and materials.  

Not complete, but more info on size can be garnered from old A5 catalogs. Some information is assumed, like the #10 YKK zippers that we used in all our stuff, and stainless steel sliders (more for durability than for corrosion).  Seam tape is also not mentioned in the material list, below.

The tubing is 6061-T6 1.125 inch outside diameter, 0.058 inch wall thickness.  Joining sections are 1" OD, 0.083" wall thickness.  Such tubing is also used frequently from hang gliding shops and can be bought in small quantities.  Corners were 1.375 inch square stock cut to 2.1 inch lengths, then the holes milled. All this from memory, but believe it is correct.







Also, for the tent pole fly entender:

Wow.  Very Cool.  

I might now have another project for my mom and I.  A few years ago I roped her into helping me make some bivy sacks.  I did the planning and since she is master sewer, she did the sewing.  Of course, being the poser that I am, I made clip-in loops just like the big wall bivys.  I few layers of seam grip and the thing is water proof.    

Thanks.
