Cuben shelter design.

I'm thinking of changing the design of some of the tie outs that aren't at risk of abrasion.
D ring on a length of 1.5oz cuben, bonded on either side of panel with reinforcement bonded over the top so that both surfaces of the panel and tie out are held.

It seems feasible that delamination in shear would be less than in peel in the same way that glue/tape bonds usually are.

Well exactly. I'm extremely impressed with the load bearing capacity of bonded seams in shear. But I'm not about to subject my nice piece of 0.51 DCF to big peel forces, because @cathyjc has already shown us the result of that.

I found where rsbtr were hiding their reduced 0.51, so 0.51 it is.
Ordered a bit extra to finish v1 which will hopefully become available cheap cheap if anyone wants a v light shelter. Also bought enough 1.5oz cuben to make another pack or three, will probably make a couple of spares if anyone fancies a pack like

They are designed to work for what I do, upto half a dozen long weekend/100 mile trails a year on established trails, they'll last several years with that kind of use, but not for the pct//Arctic/bushwhacking :)

Looks tasty :) i’d be interested in your shelter and one of your packs if they are going? i do like testing new stuff and i’m in need of a super light shelter :thumbsup:

I'm just making a very small modification to my notch li so I don't really belong in this thread, forgive me my trespass.

BUT I'm going to add some perimeter tie outs for which @Enzo has very kindly given me some suitable weight cuben scraps. A few days ago I saw his suggestion of using D rings which also seems good. I would like to use 12mm D rings but can only find 4 on ebay, I could look harder but read on. I had planned to use 2 tie-outs per panel of the tent, so 8 in total, but now I'm thinking that 1 tie out per panel should suffice (and happily equals the number of available D rings). The panel length from pitchloc to vestibule tie out is 154cm. Do you think 1 perimeter tie out per panel is too much stress? After all, it doesn't take much stress, it's just to stop the bottom edge flapping around and catching wind in high wind. Yet two seems to be the correct number. The sil Notch has two per panel as I remember.

I can't answer your question, but if you need more than 4, @paul does the stick on lineloc3s. They're very good.

I'd go for one per panel as per sil, otherwise it could make evening up the pitch laborious.

I don't see the need for D rings. Just grosgrain and bungee loops are adequate I think.
D rings unless fixed well, often rotate to the wrong orientation. Tarptent gave up on them too on the strat, for that reason and now use circular rings.

Clare, if you would still like to go with d rings, I use the ones henge hammocks sell on eBay. I use them rather than grosgrain on cuben because I'd prefer to bond than sew onto 0.51oz that rules out grosgrain, and if you use cuben tieout I think a d ring is a sensible precaution against abrasion. YMMV.

I think the sil is 2 per panel but the laboriousness point still stands. ok will abandon D rings.
Ok. My sil Notch just has one each panel (4 extra pegs if all used).

That makes sense. I didn't consider the cuben aspect. Looks like there is grosgrain on the Notch Li pitchlok tiepoints, but only sewn into seams. Trying to go into a simple edge (with grosgrain) might be inadvisable.

Also the Beastee 'D' rings from Henge are a different design to the old simple D rings Tarptent used. Beastee, though D shaped perimeter have actually more ring shaped holes, so no corners inside to pull D ring to wrong position.

Well that's a very superior sort of D ring, my goodness. I've ordered some. I will attach with 12mm cuben strips and then an overpatch for strength and to look real pro.

Any particular reason that you prefer them to @paul's stick on linelocs that I linked to above? I like the circular cut of the Treadlight ones, and It looks as if you could use them as semi-circles on both sides of the fly.

I'd not looked at those because I'd assumed they were midpanel tieouts really, and also, for the Notch perimeter, IMO linelocs are unnecessary/OTT . It just needs simple shock cord loops like used on a lot of tents.

But they do look useable folded like you describe, and could snip the Linelocs off.

Edit: afterthought- if I was using the ones I linked to, I'd think I'd stick them on the inside of the shelter hem, to preserve the smooth look of the cuben walls.

given a choice I'd go with half round reinforcement, though triangles are a better use of expensive materials.

With thanks to all for evolving thoughts on perimeter tie out fabrication. I now present cuben 2.92 circles folded over edge with gg tabs sewed on and glued with seam grip wp.

The cuben is probably a bit ott for the application and I could have used the lighter stuff that enzo gave me. In fact I wish I had. Is there any way to ‘melt’ the seam grip off if I want to change it later? Xylene?

They look good Clare, agree with Whiteburn, hybrid having DCF on the back I don't think you could melt the glue through that layer.

But I regret those grey patches now :photogenic: and want to take them off! Waaa! Will try putting xylene on a scrap and see what happens

'spose you could work from the edge and progressively ease them off. You could also try nail polish remover/acetone, dunno if it's much better than a lung full of xylene...

Keep looking at my 7.5 yds of 0.51.
To make the most of it I'm tempted to use a bit of it to get v1 working better and add 2 more meters and make a 2.7m square 1.5m high mid. Along the lines of an ultamid 4. I wouldn't choose to use 0.51 to make such a big shelter, but it's what I have.

On my calculator you'd need 8.66 yards for the ultamid copy.

I made it a smidge over 8m :)
Is it worth doing in 0.51 for a lowland shelter?
Opinions?
I'd much prefer in 0.8 and have it as a winter palace.
Ultamid 2 might be doable with what I have, and less overlap with my knot shelter, but less efficient with cuben.
