How to make this cut? Help please

[Zac wingert]

I’m going to make a lazy Susan/spice rack because the plastic one broke and naturally I saw it as an opportunity for a small project.

example I found with google
397651

Specifically, how do I remove the centers so that there is the lip around the edges of the radius. I’m guessing with a router, but how? Everything I think of would result in a groove/cove only. Freehand from one side to the other so I still have high points for the base to reference? Thanks

You could use a router bowl bit like this https://www.google.ca/url?sa=i&source=images&cd=&ved=2ahUKEwjFkKSJ-vjeAhUUFzQIHdlBA8MQjRx6BAgBEAU&url=http%3A%2F%2Fwww.precisionbits.com%2F1-1-8-diameter-bowl-and-tray-router-bit-1-4-shank-yonico-14959q.html&psig=AOvVaw03PyKJgXD1S-2GnWk449be&ust=1543558583520634

that and make you a circle template and run that bowel bit real shallow

[Zac wingert]

Thank you, but even with that but what do I reference off of once most of the waste is removed? How would I go about making n g the circle template?

[Wayne Lomman]

Use a router with a circular base. Make the template to suit using the outside edge of the router base as the guide. This leaves you space to work from one side to the other. Machine the centre out first and cut the outside shape after. This gives you more material to keep the router base on at the end of the job and also something to attach the jig to. Cheers

You could do it with a router, but unless there's something unseen about it's construction, I'd do it on a lathe.

Draw the form out on wood.
Mark the points for the dowels.( spindles) While simultaneously marking the center.
Drill the holes for the dowels.(spindles)
Rough cut the circle
Put each "shelf" on a lathe and have at it. Your imagination is your only boundary on the edge profile you create.
It's basically two turned platters with some dowels in between. You could even turn your own spindles, instead of those plain dowels.

you could use a circle router jig, or you could make it in 2 pieces. Use a bandsaw or a router jig to make the circle, then make the outside/ 2nd layer as a segmentation

+1 on this. Cut the blank in half, saw off the lip, resaw the cores and glue it all back together.

Pin router...

[Jim Becker]

You can use the bit illustrated above with a template mounted on the workpiece with double sided tape and with the router mounted on a piece of sheet goods that spans the "hole" in the template no matter where you are cutting. The bearing runs around the edge of the template to get that lip so it follows the contour and the rest is just machined out by moving the bit across the workpiece. Multiple passes/depths are best...don't try an hog it out all at once. If you don't want the rounded corner, you could also use a "short" straight bit with a bearing in the same manner.

This video shows how to use a bowl bit and what Jim is suggesting re the base of the router. https://www.youtube.com/watch?v=UJ-RKZezXl8
