So I was looking at making a longboard for myself and thought I should make a mold for me and my friends. Now I know this is probably not going to work but what if I got an old longboard deck and put it inside of a box of some sort and poured concrete or something around it that would form a strong mold? Like this but with a longboard and concrete and of course not wrap in with a cardboard box lol

Concrete is just going to crack, and you wouldn't be able to make a mold that way at all anyway. Just take two tiles and sandwich the plies in there, you don't need kicks on a longboard.

But on DIY skate they say you can use concrete for a regular skateboard mold. All I want to do is build a rectagle out of some pieces of wood and fill it with concrete to make two rectangles made of concrete. Something along the lines of this

It would be super dope if someone made drop through truck mounts for a fingerlongboard.

That would be soooooooo cool.

Well Bondo/concrete is gonna be really hard to mold it. It will probably just crack :/ If you know someone with a metal mold I bet you could get the plies pressed down and shape the kicks into the longboard shape. Sorry this is a tricky one :/

Do you have thay big of a press? Concrete would probably crack. Male one out of wood.
