I need to cut an oval panel that is 3” smaller than my existing oval table top. any suggestions for doing this? it needs to match the tabletop, just 3” smaller all around.
thanks for the input.

either make a template of the existing table top and use a router and combination of a flush trim and rabbeting bit to take the 3 inches away (the router bits keep it all in line). or make the template and wrap a piece of thin wood around it so that you can index off of it. then use a wheel that had the same radius as the reduction you want and trace around the inside and then cut it out and everything. wheels are the key to keeping it all right and everything.

You need simple jig. Attach a pin or small bearing as an edge guide on the bottom of router sub-base just 3” away of the center of you router less the diameter of the bit. Use your existing table (if possible) as the the template and cut the new table top.

I think Ryobi Router has this wheel (bearing) type of edge guide that can be mounted to straight edge guide fence.

Outline the table on luan or masonite, set scribe to 1 1/2 inches, redraw the perimeter from the template minus the 1 1/2 in and you’ve got the same shape, 3 in smaller. Now a flush trim bit or a straight bit and bushing will cut a new top. Best of luck, hope this helps, BTKS
