    Hello everyone I would really like to know if 15mm thick plywood is strong enough for a slingshot because it's really hard to find 18mm thick plywood here and it is really expensive please reply!

    I think 15 mm will do fine but if you are unsure stresstest a piece first!

    Yup, depends on the layers. I have some 10mm with 7 layers which is much stronger than some 15mm construction grade ply with 5 layers that ive seen.

    It really depends on the design you plan to make. I just completed a slingshot using 1/2" (~12mm) birch multiplex. I was concerned about the strength of it, but it worked out just fine for the design. If you plan to make high, narrow forks, it would be different than if you're doing shorter, wider forks. The 15mm should be fine for a variety of styles. I know I would trust it now.
