I agree with Martin's idea. Make it two piece and glue together. Then you have more and easier options. I am guessing that the seam would never show from the front and be very inconspicuous on the back.

Thanks for all of the suggestions. I think I'm going to try the ball mill. Going to Harbor Freight this morning, I'll see if they have them.
Lester, make sure the piece is clamped down to the table. Don't plunge the ball mill down too fast, use a steady feed.
Let us know how it works.

I would tilt the table on a drill press to 45* and use a bottom cutting endmill the radius of the cutout and lower the endmill with the quill of the drill press to cut out the shape. Set a quill stop so you don't run into the groove if you can.

In thinking about it, I would use a plunge router for this if repeatable results are what you're after. Hot glue an appropriately angled "fence" to the aft side of the router baseplate to create the angle/tilt you need. Cut this fence at your table saw from some scrap. Maybe a locating stop at the fore side would be good also since you have many to do. Experiment with the depth of cut to get the recess you want such that cutting the groove subsequently will erase the part of the bore you don't want. I would try a 3/4" round nose bit because I happen to have one, and at the right depth it should give you a scallop as opposed to a straight hole, resembling what you did by hand. Once you have this set up, you can blow through your blanks in short order. Secure the blank to the bench in any number of ways. I'd use a combination square or a scrap spacer to set the left/right position in under 2 seconds. Maybe a bit of sandpaper under the angled fence to resist movement.
I don't like cutting/re-gluing because it takes time and clamps x30. I'd say once you have the set-up I'm describing, you should be able to do them all in about 15 minutes and they'll be identical.
