Advice...kurf at angles?

I want to take two pieces of birch plywood 3’ x 4’ was wondering how would I go about putting like one small wave affect in it? I know about kurfing but I’ve never seen it done at angle. Help please. Thanks

Interesting question. Can you draw a picture of what you’re wanting to do?

Are you talking about cutting a series of kerfs to allow the sheet to flex? How much of an angle are you needing to cut it at? Depending on how the kerfs are oriented, the easiest way may be to attach a second piece to it with double sided tape or masking tape and super glue. Attach it at the correct angle to allow you to run the second piece against the fence, then saw like normal.



What the heck is that?

I don’t know how closely you want to match that, but in a sheet of wood, without a press it will be difficult to do. Unless it’s just the way it photographs, that isa cookies shape. It curves in two directions. Here’s another example of something with that shape.

As you can see it doesn’t have a cylindrical shape, which is what you get if you bend a sheet of material along one axis. Again, maybe a simple bend is what you want, but it won’t match that ps exactly if that’s what you want it to do.

I’m wanting to make a giant ps5, so I’d want it as close a it really is as possible. All I have is plywood. In my head I thought I could somehow kurf the wood then glue it and wrap to hold the curved shape. I just dont the way that’d be possible.

It’s subtle, so most people probably wouldn’t notice the opposing curvature. If you already have material, then you have what you have. If I was going to do a large radius curve, I would laminate multiple sheets of thinner material over a form, or a buck, to get the shape without weakening the material from cutting a bunch of it away.

I would use the laser to cut the shapes using living hinges to create those curves. then Use veneer as the top layer with a vacuum bag form. Lots of choices though.

I think I know what you ur talking about, but then again some of what ur say I’ve never heard of lol. I need ur help on everything I wanna build in my head

I never thought to use the laser cutter, I guess multiple passes would be needed to go 3/4 plywood.

I wouldnt use anything over 1/4 and that’s pushing it. i was thinking an 1/8 inch baltic birch plywood. You wont get much movement using a living hinge on anything thick. If you are set on something thick, glue multiple together and use the shopbot to make the waves. All depends on how much time and money you want to spend on this project.

I think you’re talking about something like this?

Yes! I think that would work. Now I just need to know where to get that type of wood and a super cool person to help me burn it
