I dunno if my knot inner will fit, worth trying. Though I'll probably use it for a 1p palace or with my Mrs so the half inner.
That locus gear is exactly what I'm planning!
My plan is to tape the two triangles that make each panel and lap fell seam and over tape the corner seams. Given I'm using 0.51 taping alone would probably be fine but I have toys I'd like to use...
Have ordered some 9mm tape that I'll use to tape the two corner panels, then roll the seam over 180 degrees and I have a 10mm double spring guide foot for my 6mm double needle machine to form a lap felled seam. Then over tape, heavier than taped alone, but a stronger seam for sewing a tie out to, and I have 10mm mini line locs coming so they should stitch on tidy.
Occasionally I see a myog cuben shelter that says it doesn't use cat cuts, but generally, and in my experience as you say you get saggy seams.
Agree that heavy deflection could put extra tension on seams, but locus gear etc show it's possible with good lifespan. I'm coming around to the idea that it's shock loads from flapping that produces the highest loads, and the tauter the pitch on balance the better.
Not made enough shelters to have a good feel for it, but I'll give it a go!
Looking at how my Cuben shelter pitches - I get a little 'loose' fabric along the side seams where it doesn't always pull tight/flat - I've considered putting a CAT cut along those seams in any new iteration of this design I make.
BUT I would make it a very small deflection - not more than 1cm - I think you could put too much tension along the seams if you ask the DCF to "stretch" in ways it's not designed to do. My instinct is that big CAT cuts are really for stretchy fabrics like Silnylon.
Nice. Looking forward to how it goes.Settled on 8cm deflection. Three of four sides done, should get 2.5yards more cuben to finish it off from ripstop on the 16th.

Not touched it this weekend, but still have three line locks to fit and the vent. Estimated finished weight 450g. Not perfect but I reckon a useful addition to the arsenal.

It'll easily fit my knot 2p inner. But I'd be tempted to make a more state of the art inner.

If I was doing it again... Which might happen (once I've paid this one off!) I'd consider 1oz cuben to make it a winter shelter with longer lifespan, Def lower the mid panel guy points, and I'd cut the 4 panels so that it pitched as a slight octo.
