    Any body ever bent sintra boards into an “L” shape, to make them self standing? how much more do i add on to each sign for the stand?I was thinkin of drawing a line ,heating it up with a heat gun and bending them over a pipe…….any other bright idea’s 😀 Kinda stumped on this one.
    Thanx People

    hi steve,

    not quite sure what sintra board is mate but whenever I bend engraving laminates to make freestanding a-frame type signs, I heat it up using a paint stripping heat gun and then bend it over a piece of 2 by 2. This way you get a nice 90 degree angle.

    Sintra Board is a foam pvc much like foamex I think Andy. If this is so then a heat gun is fine to apply heat, bend using a block or the edge of a metal table as Andy says this way you get a nice clean 90 degree bend, unless you dont want a sharp bend in which case a piece of pipe would do.
    It will of course be a bit more difficult to bend the board squarely useing a piece of pipe and a bit more difficult to bend it to the correct angle.

    Just to finish off the topic, i usually score the foamex board on the table saw, with the blade set at 45 deg, this gives you a very accurate nice bend.

    when youre bending, hang the shorter bit off the bench, using the score line (facing skyward) as a guide to the end of the bench, heat gently with a hot air gun , when ready to bend just pull back on the bench with a block of wood and fold up to meet the block of wood
