For a locked brummel Samson recommend 2.25fid lengths (1fid =21 x rope diameter).
For 1mm 8 strand?
FWIW, The locked brummel is harder to make than a sewn splice and also weaker. I havent done a locked brummel in years, I just sew some thread down the splice with the machine.
Samson is a good source for fid values, as is English Braids/Marlow, New England ropes, Gottifredi Maffioli, Lyros.
Hi Teepee - Samson don't do 1mm but I think it would still stand, I use it for 1.75mm Zingit/Lashit with a locked Brummel. Personally I don't find it that difficult to do a locked brummel though I haven't tried 1mm yet. The weak point of a whoopie sling or UCR will at the point where the adjustable part exits the bury as there is a sudden transition in size - this is where a rope will break.
It will be a longer bury with 1mm but it's probably a moot point for this application. Liros do a 1mm hollow braid but I can't find the splicing info for it on their site.
Here is the Liros splicing instructions and they say 40 x diameter which is even shorter. Is there any reason 1mm would be different? I admire you guys splicing 1mm that is some seriously small cord .
40mm!? Their splicing video shows a bury about normal length. Their taper is 100mm .
Besides, still good to find the data for a whoopie sling as it's usually a longer bury.
40mm - does sound short doesn't it? Only one way to find out if it works . I usually do a bury of 90mm in 1.75mm Zingit including the taper.
That's some interesting info there folks.
I've been going with 50 X diameter for locked brummels and I measured my old Whoopie bury for new ones which were about 10 inches.
My thought was that for a low load application like guy lines you could go shorter and have more adjustment.
The Bury on my ridge line Whoopie, 2.2mm, i made shorter at about 25 X diameter and that seems to be ok
OK, OK, I didn't make a pair of Merrell Moabs, but I did make a hole disappear... and make them waterproof again!
Bunged up a split near the toe with bathroom sealant.
and smeared the bottom inch or so with the stuff too.
3 days in, working pretty good so far.
Bit disappointed the Merrells only lasted 6 months tho' (prolly knockoffs, I guess).
Summer nest for the Duomid, 2.1m * 0.7m * 1.2 high, 253g inc tie outs.
36g/m2 cuben bathtub with 125mm walls; 27g/m2 ‘pertex’ walls 175mm high (225 at back); 27g/m2 no-see -um mesh; #3 zipper.
Wow that's I seriously nice build!
Agreed, looks brilliant!
Looks 'the business' @Whiteburn and a good 200g lighter than my nest. Can't quite tell, looks like you didn't go for struts at the corners, the bathtub forms itself naturally through the design?
Found with my first go around (winter nest with 3 solid walls) that with correct positioning of the tie outs that the corner struts were unnecessary with the Duomid; obviously wouldn't pitch too well as a stand alone bug shelter.
Smiley Ron Cone Sleeve
My original Trail Designs Sidewinder Tyvek cone sleeve was getting a bit tatty at the top and bottom. Replacement took 5 minutes:
1. Take one Tyvek envelope as used by Ron etc.
2. Remove expensive gear from envelope under cover of darkness (covert)
3. Use existing envelope as is i.e. 2 ply or if Ron has deviated from his standard smiley dimensions, cut the envelope at its glued edges and fold that in two to ensure you get all the smiley
4. Mark out TD original cone sleeve on envelope material and cut or use as a template and simply cut around it.
5. Stitch the seam, which will be slightly curved.
Kevlar composite pot lids.
I bought some kevlar for a chew resistant food bag but it was a disaster, the weave easily pulled apart. Anyway I thought a composite lid would be cool so a trip to the pound shop for epoxy resin and Teflon cookie sheet. Watered down the epoxy with alcohol, and made a soaked small 3 layer, a soaked 3 layer with curved edges (unfortunately with bubbles!) and a 5 layer which was three layers of sticky, starting to set mess so I quickly stuck a layer on each side.
Interesting project, I like the basic disk lid. What do you think the advantages are over say a Reflectix or foil lid - might it melt at the point of contact with the pot rim?
Have you had chance to pop them on the weighing scales?
Well they're definitely more robust than foil and kevlar is fire resistant, I've no idea about how insulating it'll be. I did try the Sierra cup with decent sized alcohol flames up on the edges and it coped very well.
Weight for the formed lid 18g, flat 5 layer 28g and the little one 11g
I think with a proper skill set and materials a 2 layer would be sufficient and probably in the 12g region for a 14cm pot. Unfortunately my attempt was a bit cack-handed.
If it was easy it'd be less interesting.
On the melting question I was thinking more about the epoxy than the kevlar.
Very true ☺
My tests haven't been at all thorough yet but the epoxy browned slightly in direct flame contact. Other than that I've no idea if it's toxic, safe etc. My 5 layer disc one is pure kevlar on the outside and I presume that'll be fine with a bit of a flame
Id guess epoxy in contact with flame will give off some nasties but most of it will go into the air rather than pot contents ans its not like we camp on a daily basis. Id consider my liability before i flogged any though
I'll have to get them smooth and flat before I could sell, it surely can't be more poisonous than a sigg.....
Ended up drinking the inner coating! Swiss quality
BTW it didn't flake off while it was cut this happened in about a month of daily use at the gym. Still one can never be satisfied with a stove setup, another fancee feast..
Oh a Sigg have no money back guarantee of anything.
Finally conical drill bit arrived and I was able to put vent holes into the windscreen I made weeks ago..of course it was time to do some drybaking for the test..so far so good
Lovely results @slovhike, looks tasty
But hungerly look at it for a while an it looks like an angry crab
Nice work !!
@Tartanferret it snapped in half while i was removing it from the pan...it didn't last long..
thank you for kind words
