    I'm working on a slingshot that involves some Pergo flooring samples from Home Depot. Am I wasting my time with this stuff? It seems hard enough, but will it take a stain? How do you guys treat it? What do you guys think, should I finish it?

    Show it to us!

    Hey mixer,

    half the world is watching!- And I (as many others) have
    no idea what you do and what material you are dealing with!
    Therefor: yes, please go on and please post picts!

    I've got some Pergo at home left over from a remodel a few years ago. I've been wondering the same thing myself. The stuff is pretty darn solid, but will it work for a slingshot? I guess you may have to tell us. I was thinking about trying to laminate 2 pieces back to back, leaving the original factory finish, then leave the filed/sanded edges as is, perhaps sealed with some poly. I'll look forward to your results.

    Be, Pergo is a name brand of laminate wood flooring. It's pretty durable. It's basically a chipped wood core with an outer layer of laminate material. It was developed in Sweden. It's less expensive than 'real' wood and it looks pretty good, in my opinion. :)

    Verdict : I will finish it :)

    Gimme another week, I only have about half hour before work every morning to work on my slingshots, and I'm about halfway there with this one. If anyone has any suggestions, especially on staining, and finishing, please chime in! Thanks guys :)

    a clue

    Now I got a clue..

    Guess we call that "Laminat"..
    8mm to 12mm thick, "resopal" ( another brand name:) )
    cover with a photo of wood..
    the lower cover just plain?..

    If so, it all depends on the right type of glue..

    If that would be epoxy (of the right kind)
    a middle layer of coloured cardboard (Or three?
    like red-blue-red) which as posted before would have to
    be soaked with the resin might look fine..

    I´m waiting for pics :)

    Greetings, good success!

    If I got it right, theres gonna be a lot of inner forces
    in the "MDF"-layers (shear force?). If parts of the fork are
    too narrow there might be damage, in the end the glue used
    for production of the "medium density fiberboard" will have to
    cope with that.. Be safe!

    First post/Pergo

    Hi, been reading the forum on how to do it yourself and found this. I did one and glued them together with TiteBond III. Need at least two days to dry up. It measured ~16mm. Look solid to me!

    super light bands only! Dangerous material.

    I say go for it and if you have any doubt your could use a harder material for a core.

    It's pressboard, might as well make a slingy out of sawdust. Any legit builder would advise against using this inferior material.

    Thanks for the advise. I'll be testing this one and be careful. My initial impression is that this is very strong and solid. Cheers!

    Keep in mind that it is amorphous, it could break anywhere without warning.

    Yeah this stuff is spooky... I made a small shooter from one layer of it back in July or so. I got a fork hit with 3/8" steel and it blew the fork right off. Laminating with an alu,steel or good plywood core would probably be ok but I wouldn't trust it alone.

    Thanks for the info! I got two of them glued together so hopefully this is stronger. I'll test it before using a stronger band. I'll strike it several times and see how it holds.

    Using a core would be great!. :)

    You might have a look at steel bridges; or concrete ceilings.
    In both cases there there is a drawforce/ pressure resistance
    element on top and bottom of the system. To prevent e.g. a bridge from
    bending, the second most important element of the system is the
    diagonal elements/beams to cope with shear-forces.
    If you regard a thick telephone book, you can literally roll it up
    in your hands; this is possible because there is nothing to prevent
    the pages from gliding on another..
    If you fully glue each side to its "neighbours", the glue will compensate
    for those forces (shear-strength) within the phonebook ("Schubkräfte"
    in german) rolling therefor is impossible.

    This is where pergo comes into play: there is two extremely hard layers
    on top and on the bottom side. But WITHIN those boards there is,
    as dolo tried to make you understand merely sawdust, highly compressed,
    with a minimum of glue to guarantee a little cohesion or "no-load
    shear strength"- for there is no shear-forces as long the boards
    don´t bend..
    What they don´t do, lying on the floor... !

    Glueing two layers together is no solution! If either outer side of that
    laminate is receiving any microscopic cracks, the system fails..
    (The more important side of the sling is the one you cannot see while
    shooting it)

    Destroy the fork, so you can see! (using both eyes as long as you life)

    - thats what I wish for you!
