I was talking with my Father-In-Law, Jerry, one day when he mentioned that one of his neighbors had a lazy Susan that he really liked and wanted to know if I could make him one of his own. I told him 'sure' so the next question I had was what size? Once I cut some cardboard to give him a better idea, he settled on 20" diameter. And the base will be 12". Oh, Jerry also supplied the bearings for the lazy Susan as well.
 

I'll be working on the base first and for that I'll be using pine.
 

Fixture Making

I'm going to need a way to cut out two different size circles, accurately. And yes I could cut these out with a jig-saw but that's not that accurate. What I have in mind is to use my router for this, along with a circle cutting jig. They sell jigs like this but I'll be making my own.
 

This is a very simple jig to make and I'll be using 1/4" MDF for mine. All I need to do is trace around the router base on one end, including the three screw holes and center location. Also, I figure while I'm making one, I might as well make two different sizes.
 

I've marked out my two sizes below. Now if you're wondering why you see a number six and ten on my fixture, this is the radius, which will produce a 12 and 20 circle once the jig pivots around. All I need to do now is drill a small hole in my work piece, but only half way through. This way you won't see anything on the top surface once I'm finished.
