Hi ceetee

Here's just one way to get the job done quick and can be used over and over..
Just chuck up a 1/2" router bit and put the 3/4" brass guide in the router base, turn the jig with the router plunged down, put in the slot outside slot then use the other holes or slot to plow out the center...

Like my memory, the formula I once knew is long gone! What I'm attempting to do is make some lazy susans with the lip idea. That should prevent items from falling off the top surface - especially if it should get spun too fast. I would like to use a 1/2" straight bit and corresponding bushing. After routing the circular groove, I'll find a way to remove the rest of the top surface - leaving only the lip sticking up. Help!


No one is ever too old to learn or practice good safety!
