Birch Plywood Cabinets made by CNC machine

Musik007 · 17th May 2011, 10:35 AM

Hello,

I'm pleased to develop a new series cabinet made by CNC machine. High precision processing of CNC machine is able to cut any shapes on plywood. This is my first sample of a bookshelf cabinet for CHR-70. The material selected is Finland WISA birch plywood.

With a CNC would it not be easy and better to NOT use right angles for the internal cavity so as to avoid parallel walls and the resulting standing waves?

I am liking that a lot! I've never made any speakers, but if and when I do, I will use that method.

The result of the unfinished or varnished ply will look very restrained and Scandinavian, or you can presumably veneer it. I'm almost tempted to start straight away...

Hi Charles,

Thanks for your remind. I want to keep the internal volume unchanged as Till 70's. I will put damping material into the cabinet.

Asymmetrical "Wavy" walls would be the way to go... Just as easy but mobedda.

While you are considering changes... why not implement at least three holes in each piece in the same spot that could be used to align all of them. For instance, you could put a threaded rod through these holes to align the pieces and clamp them together while gluing the stack together...

Also, +1 on not using parallel, rectilinear inside walls.

Hi Charlie,

Thanks for your recommendation. That is possible to do like this.

Thanks,
Tony.
