Any idea how I would make these cuts? Four cuts, same on each side.

I think we’re gonna need a bigger picture.

With the appropriate jig they could be cut on a table saw sideways. (like cove mouldings)
Just a thought, there is undoubtedly an easier way.

Two pieces of rails cut on a bandsaw with the desired curve (cut both at the same timeso that they’re the same) and make a router sled. Make a jig with the rails. I actually think that this would be super easy.

My guess would be it was done on a lathe
and then cut square.

You can devise a router jig to carve a dish.

My first thought was that it was done on a lathe, as well.

Does it not go to a point in the center?

Yes it does.

Make a router sled!

Probably router and a sled is easiest way.

Radial arm saw.
Turn the blade sideways.
Make a jig to hold the work piece at an angle.
Make cuts lowering the saw blade 1/8” at a time.
Something like this:

It’s turned on a lathe, cut apart, and glued back together. Similar concept to inside out turning.

Check out the router jigs for making the scoop cuts for seat bottoms. Basically a two axis sled. The X axis is the U and the Y axis is a wedge.

When the sled is all the way down the Y axis, you go left and right in the X axis U establishing the nice curved cut side to side at the edge. Then you start moving up the Y axis wedge while going back and forth in the U.

So basically you are cutting a climbing U and at the top of the wedge in the middle the bit basically lifts off the piece when the router is in the bottom of the U.

Rotate the piece and repeat for all the sides, resulting in the four way closure in the middle and each edge having the gentle curve corner to corner.

It’s hard to tell from the picture because it’s
so small. If it is the shape shown in Jbay’s
drawing, then it could also simply be carved
out with power or hand tools. Perhaps it
way shaped on a the end of a belt sander.

Cut diagonally into 4 pieces and turn them around. Think segmented turning.

If you turn a square piece on a lathe, you get something like this:

Make 2, cut them diagonally and turn them around so the outside corners become the center. The bottom probably wouldn’t be curved, it could be flat.
