Good morning!

I'm planning my first project with my new Bosch router. I'm making a pair of Lazy Susan shelf units for canned goods. I need to cut 8 15" circles out of some old high grade 3/4" plywood I got at the local Habitat store. I have a 3/8" Freud spiral upcut bit coming soon, and I plan to use it with the Bosch edge guide circle attachment.

I searched this forum, and I did find advice that this is a successive pass proposition, but that's all. As I'm making eight of these, I don't want to be at it all day. I'm thinking three passes per circle, but I'd like to avoid too much split out of the plywood.
I plan to plunge this, but if it's easier, I could use the other base and twist the motor into the cut.

Thoughts? Thank you in advance. Hope your day goes well!

do you have a bandsaw or jig saw ?
with a plexi faceplate on the router, you can make them consitently the same size.

I could make one of 1/4" plywood easily enough, and I could then use a screw for the center, rather than that tape business. Would that be easier to use than the RA1054 circle attachment?

So I did two passes with a 1/4" spiral downcut on all thirteen circles, with a thin plywood homemade circle gauge I got for a dollar at the local Habitat ReStore, with a cabinet screw in the center of each circle, then went back and finished each one with an upcut bit. I can tell that twenty-six passes of about 50" (16" circles) did dull the bit just a bit, but it is still useable. Combining the two was a great idea! Thank you for giving me this solution! There are two lazy Susans, one has two taller levels for juice bottles and such.
