MYOG - cuben shelter

    Why ?? - I've been using TN Laser Comp which with mods and proper pegs, is nearly 1300gms. If I'm going to invest in something lighter then I need to loose about 500gms - so a cuben mid is probably the only way to go. For me the Laser is OK space wise, but I wouldn't complain if I ended up with a bigger shelter . A less flappy shelter would be nice too.:D

    MYOG ?? - I can get exactly what I want and I love a challenge :D.

    Cost ?? To buy - Too much. Think I can save about £200 over what I might have bought ready made. As it is the 'ingredients' I've got so far come in at about £230 :eek:. Hopefully I'll have cuben left over to make all sorts of other bits and bobs.

    How ?? - I've been researching online - but I'll be on here looking for help and support ;) Hoping to bond as many seams as possible.

    When ?? - Hubby is away for 3 weeks in March so I'm grabbing the opportunity for some space, and peace and quiet then :D

    What ?? I've been thinking about this project for months. I decided on something in size between an MLD solomid and a duomid - partly as it gives the most efficient layout of panels on cuben 138cms wide, and because the solomid is a bit small and duomid is more than I need. The large 'flat' back panel seems a weak point on the MLD mids and I'm planning on having a point/beak at back and front. Should negate the need for a mid panel 'pull out' and be a better shape to hold shape and shed wind. I was very interested to see Robin (? have I got the correct name?) has come to the same conclusion on his Tramplite, which looks brilliant. But I want full coverage all round with proper zipped doors. I want to get the Fly right first - inner can come later.

    Stuff I still need to sort

    Vents - I need to get a look at these on someone's duomid etc. to see how it's done. Working on it but pics and any info. comments welcome.

    Reinforcements - I need some small pieces of heavyweight cuben for these but Extem Textil only sell a minimum of a meter at a time - has anyone got small pieces I could acquire ?? Same problem with a bit of dyneema for the peak/top of the tent where the pole goes - any offers ?? Please :)

    OK - 'nuff for now. Please chip in with your contributions - I'll be months before I'm done. :D

    Don't copy the MLD mid vents is my advice, they are not a great design.

    Nice One Cathy.

    An expensive MYOG project:eek:

    (Think you mean Colin Ibbotson - Robin owns one of his Tramplite shelters)

    I agree re the pointy bits. But it makes reaching the base of the door zip harder (assuming it's at the point?)

    MLD vent on the solomid I had was *****.

    The low edge is too high so it wouldn't close as MLD claimed they do. The velcros just wouldnt meet except at the very edges.
    Took multiple photos, made measurements and wrote description and played email ping pong with Ron Bell - just gave up in the end - he is either obtuse or arrogant -was unwilling to even countenance there was a problem.

    Locus gears vent seems a better design - has insect netting too.

    Thanks for the name correction - I couldn't remember and too complicated to hunt around for it.

    Zip at pointy bit - but not too pointy - probably not quite as hexagonal as SL3 or Hex.

    Paul - thanks. I'm using the black 19g/m stuff. Well mostly:confused: - I've had to take some in green as there wasn't enough in stock of any one colour. I like the black best.

    Mole, I was hoping to incorporate some noseeum in the vents.

    I don't like the stiff bars in the DuoMid vents, I keep meaning to take mine out and see if they'll stay open, would make packing a bit easier too.
  11. Mole

    Mole Thru Hiker

    oh it'll stay 'open' somewhat - it's if you want to close it you have a problem!
    the stiffener is easy to take out anyhow - why not do it before you pack, and store the cable tie lengthways down the pack?

    Is that what it is in there, I've never properly looked.

    My comments about the vents well covered by the above.

    You can get away without making a hooded vent. They are clumsy. e.g. on Duomid....they are a pain when it comes to rolling up and packing away. Keep the design as simple as poss'. Adapt the area at the top of the zip so it can be left open. The top of the zip area can have a larger flap of cuben incorporated around it to prevent ingress of water. Held open with a piece of stiff Velcro.

    Great idea LG. Simpler , neater and probably just as functional. A 2 way zip ..... wonder why doesn't the duomid have one ? :confused:

    cathyjc Thru Hiker

    I was planning 2 way zip - why wouldn't you ? :confused:. And linelocks as standard.

    Will think about running the zip higher, under a cover, to provide ventilation - I wonder if zip would slip/unzip when wind creates tension in the surrounding fabric ??
    Zip - I ordered YYK 5c - but it looks much too chunky/heavyweight for the fabric. Would 3c be tough enough ?? - Comments please.
    And Exteme sent a double quantity of zip (not charged :D) so surplus may be looking for a home - wait and see o_O.

    And most important my shelter needs a name. Calling it "my cuban MYOG shelter" is too long a handle.
    I thought - "The Howff" :D.

    It shouldn't at top Magnitude more tension at bottom. I've had several shelters with 2 way zips. Inc the Golite Hex and Oware mid. Never had an issue.
  19. Mole

    Mole Thru Hiker

    I wouldn't use 3C unless not under much tension. (Inners). Or easily replaceable.
    My Scarp has 3C. One zip has separated after fastening a couple of times Last year. Not impressed. Weak point of Tarptents.
    There was a recentish discussion on BPL. The majority agreed. Several examples given of 3C failing on inners.

    My hex and oware both 5C

    Thanks Mole :)

    I wholeheartedly agree. Hence my comment that I think it is strange that the duomid doesn't use one. 2 way zip using the top as an integrated covered vent seems a neat solution.

    Here's a photo of a vent I had on a Hexamid Twin, which I thought worked rather well.
    Twin vent.jpg
    A carbon fibre rod fits into the triangular pocket and a bungee cord runs from the circular reinforcement, up through a loop attached to the triangular pocket and through a cord lock.The bungee/cord lock can be loosened and the carbon rod removed from the triangular pocket and the bungee retightened to close the vent. The carbon fibre rod is held in place by a cord attached to the square reinforcement patch. The cord runs up through the rod. Originally, the cord was knotted at the upper end so the rod was permanently attached to the tent. I was worried about stressing the tent when packing up the tent tightly with the rod attached so I undid the knot and threaded the cord through the rod each time when setting up the tent.

    Looking forward to this :)

    For the reinforcements, I think most of the fabric from ET is available in any length you want as long as it's 0.5m minimum
