Devon Bunks and fittings?

Discussion in 'Mech Tech' started by carlperkins001, Dec 8, 2012.

  1. hey guys, i got a '75 devon. The previous owner had rivited some really dodgy home-made bed in the top and binned the bunks.

    I managed to get some bunks from the local breakers yard for £20. but its missing the three hooks that it attaches to when opened.

    i think they look like this..

    Is thats right? and if so.. has anyone got any that they can give me the dimensions of so i can get one made??

    cheers
     
  2. Send me a pm in the morning to remind me. I will have a measure. I have the single hooks. Not sure about the double one.
     
  3. Ok cheers will do, the single hooks would be easy to make, the double one not so much.

    Not really sure what to do about fitting these bunks.

    Does anyone know how to bunk material fits to the side of the van?
     
  4. It's so long since i've looked at mine, but i think they're riveted. I'm fairly sure the edge of the bunk and the bunk cover are riveted together, then when you collapse the bunk the cover folds over. Found some pics.

  5. I have measured the single hook with a digital guage and put the images http://vwt2bay.webs.com/pictures.htm It is easier to upload to my own site rather than on here. The top hole center is 9mm down and the second hole center is 15mm from the first.

    I can't flipping find the other bracket and am now wondering if it came with the van :'(

    If you get the size for it and make 2 I will buy one off you :)

  6. Haha yeah ok will do, i think ive found a local engineering company that can make one for me. A friend of mine managed to find and give me a spare single hook, so now have one i can get copied.

    As for the bunk material.. If the material was rivited to the cover and then into the side of the van, would that hold much weight?

    Cheers for the help people!

  7. Hey carl, i was going to pm you to say my van's at my mum's and i don't get there very often, so pics might have to wait. Then i noticed i'm working on a devon now. Doh!!
    Here's some pics, let me know if you need any other pics or measurments. Cheers

  8. cheers man thats brilliant! if you get time could you get me 3 more measurements?

    ive marked them out in this pic...

    the vertical one that crosses over is the thing that sticks up in the middle.

    by guessing i thought that the bottom left one would be 15mm, the middle bit is 10mm and the two top curve bits i have no idea, maybe 2cm out and 1cm up?

    cheers for the help man! its much appreciated

    Carl.
     
  9. Hi carl,
    The bottom line is 2.5cm,
    The vertical bit is 4.5cm from the bottom of the plate to the top of the tab between the hooks.
    The horizontal section of the hook is 2.5cm with the curve starting at about 1.5cm
    The vertical section is 1.5cm from the tip to the horizontal.
    The plate is made of 3 mm steel by the way.
     
  10. Nice one cheers mate. Bugger i bought 5mm steel.
    Ill update when ive made the thing.

    Thanks!
     
  11. managed to make up the fittings today. theyre not 100% yet, still need some drilling, filing etc.

    i forgot to take pictures of when i was making the bigger bracket, but it was just a 3mm plate with the dimensions marked out on it, cut, bend, cut, file and so on.

    he outer edge of the bunk is a ? 12mm x4mm round-edged metal bar which traps the fabric. The bar is then screwed to the roof metal every 15cm or so.

    When I replaced mine, I used yacht lacing eyes (little metal arches) which I screwed to the sides with self-tapping screws about every 10cm.

    (its what happens when the nearest hardware store is a yacht chandler)

    The bunk fabric is doubled up, the edges meet at the bus roof. Each edge is folded over to make something for eyelets to fit into. A cord is threaded through the doubled over bit so the ends can be tied to the eyelets at each end. This is critical, as when you are in the bunk, the fabric stretches and the cord actually stops the eyelets pulling out of the fabric


    Roof edge of bunk

    ---------------------------------Fabric edge
    ================== Cord pulled tight
    /------
    | | Eyelet
    ------/

    bunk fabric


    I then fitted reinforced eyelets to the bunk material so that the cord running along the edge is 'outside' all of the eyelets, and then laced the whole lot to the eyes with 4mm terylene cord. Then by undoing the cord, I can remove the bunk fabric. The cord running along the inside edge of the fabric is stretched very tight.



    It will take my 15 stone weight although the general blubber doesnt really fit the bunk.

    Have any of you been on one of these bunks?
    Best place is the bin IMHO.

  15. The bunks are good for kids and they are pretty strong. It's a bit claustrophobic when you have both bunks out and you're sleeping under them.

    They're strong enough, but tiny and very difficult to get in and out of.

  18. Hi,
    I understand this thread hasn’t been active for many years but I need to make up some brackets to attach our hammocks to our Devon Bay. I’ve tried to access the files above but they seem unavailable now. Does anyone have any images, drawings or measurements that would help me with this?
    Thank you so much.

    Without measurements I would cut the shapes out of thin metal, bend to shape, adjust them and then copy them in heavier gauge metal.
    The main thing is to be thick enough to take the weight of the bunk and the 15 stone person trying it at one end.. all going through two about 4mm diameter woodscrews.
