Made this box out of 8/4 cherry scraps from cutting boards I make. It was a very simple design in Inkscape, 3 concentric elipses. Then ESTLCAM and hours to pocket out the bottom and top of the box, then part out both. A 1/4" lip on the top keeps the top aligned to the bottom. I will be adding felt inside the bottom and inside the top of the box and will add multiple coats of poly to finish it off.
Two sided milling. That’s some advanced stuff! Nicely done!
I agree! How did you do the two side part milling? Lately I have milled holes into my spoil board and then used dowels to locate.
I have to concentric elipses to work with (actually there are three, but the third elipse is for the for top).

In ESTLCAM I used hole and then pocket to cut out the inside elipse. I then parted out the outside elipse. I used a 1/4" two flute end mill for both cuts.

The most critical piece is making sure I had an end mill long enough for my cut, which was 1 1/2" deep with a floor that is 1/2" and walls that are 1/4". That and tons of time to monitor the 3 hour cut. Obviously, you could make a more shallow box.
For the top, use all three rings…

If you look closely between the hole and the part cuts, you can see the lip that fits into the bottom of the box.

I said it in a post on my build, but I did the box bottom, then the top and various other cuts for 10 hours yesterday and this machine just keeps on going… it’s a tank. I love it! I just did a Hylian Shield and am now doing a Punisher plaque… too much fun. I think I’m obsessed… is the a support group for too much MPCNC? Might have to sign me up.
It looks fantastic even before finishing - great work!
