    I'm getting faster at making sandwich boards. Today I made
    two in about an hour. This time I made them with nice timber
    sheet instead of chipboard using my Bunnings Warehouse gift
    voucher. 🙂 (I also bought about 500 screws!)

    Anyway, I thought I'd share a couple of tips that I've
    learned with experience.

    1) Use plenty of (but not too much) glue.

    2) I suggest this pattern for the screws joining the plank
    to sheets (going into sheets first)...low, high, low,
    high, low. What I mean is I've been putting the screws
    in in a zigzag pattern to use the full width of the
    planks. I think it's best to have three low ones because
    if I'm not mistaken there's more force in that
    direction. I'll make a diagram to explain my reasoning
    if you want. I'm not sure if it's correct.

    This screw pattern also results in there being more room to
    work with when fitting your hinges. You place the hinges on
    the sides which is where the screws are positioned lower and
    the hinges are automatically higher so it works out nicely.

    Do you think using 16 screws to attach the hinges was
    overkill? I decided since I have 300 of that size anyway I'd
    just go for it.

    Now I'm off to go hopping and gapping on 1 ugly (my first,
    lazy attempt) and 3 beautiful sandwich boards. 🙂

    They look really well put together, Andrew. The only thing I
    worry about, though, is, since the grain is going sideways,
    you run the chance of just splitting the board in half when
    you hop onto it. Be ready for that to happen so that you're
    not surprised. They also may warp in the sun.

    Heavy-duty plywood should eliminate both possibilities.

    I did consider that when I bought them but that was the only
    way they were available. They're between 20 and 30mm thick
    and seem very sturdy, plus I'm pretty light so hopefully I
    won't have any problems.

    As for them warping, will they be fine as long as they're
    not stored in the sun?

    I just set up a really great trials line with my 4 and a
    half sandwich boards (the half is my suicide mount
    board...one wiht only the planks and hinges) that goes
    around in an arc then up onto a big boulder and onto my
    letterbox. I haven't managed to do it all yet and it's
    really hot outside. I've just come in for a break and I'm
    going out for a second batch of attempts soon. Wish me luck!

    i like the ones with the 2x4 on the outside so it closes
    flat and is easier to port.

    Hey Andrew I would say your best bet is to put some 2x2 or
    anything available against the grain, probably best on
    either end. They look good but with hopping on them and
    everything, I'm thinking they will split. Maybe possibly who
    knows, but its worth the extra few cuts and time.

    That grain looks very break happy to me too! So, if you decide not to
    re-inforce them, at least have your buddies shoot video when your
    hopping. I wanna see the fall! 😄 --chirokid--

    By the way, 20-30mm thick was a typo....I meant more like
    10-20mm. Yes, I did consider bracing them with some planks.
    I might still do that. I've been hopping around on them this
    afternoon and they do feel solid.

    I like these ones with the planks on the inside because I
    think that although they are the same width at the top, they
    look narrower. Even though they don't fold up flush
    together, you can place one inside the other which saves
    some space.

    Check out www.unicyclist.com/gallery/albuu61 if you want to
    see how I used them this afternoon (or one of the ways
    anyway). I did eventually clean the line. It was fun. 🙂
