The hole is shown in this page https://www.benjaminsalley.com/inthe...-palettes.html
I appreciate your help.

If the angle of the hole's walls is the same for the whole circumference, mount the palette on an angle jig so the walls are vertical then come in with a pocket, contour or even boring operation.

If the angle is changing or your machine won't support the Z height needed to clear the palette on the angle, look at mounting it flat on a jig that incorporates a spoil board, rough out with a straight cutter and then put the angled faces on using a spherical ball mill aka lollipop cutter.

Thanks for your answer. I think the angle is not the same for the whole circumference, right?
Are the methods you described CNC, or manual machining?

Cut the elliptical hole on the CNC, then wrap sandpaper around a dowel, and sand in the angle by hand.

Thanks. It is better to machine the angle than make it by hand, right? What is the name of the angled surface?

Use a "lollipop" cutter.

By sanding's a great idea if there's only one or a few to do. If you're belting out hundreds then I'd be trying to automate it.

I'm thinking those techniques would work for either manual or CNC, the only difference is it's tough doing an ellipse on a manual table.

You'd probably need a really long tool to CNC the angle.
A better option than hand sanding would be a spindle sander with an angled table. It would only take a few seconds each, if you were making a lot of them.

I will look into that. Thanks

I want to make a large quantity and sell them, and looking into the method and cost of doing that. Thanks

OK, thanks for the info. I will look into the spindle sander.
