Woodworking gurus - need help with a specific design

I take it you don't have a router table. If you had one of them with proper guides, it would be a piece of cake to do that removal and there is a simple technique you could follow to remove most all of it except squaring up the corners, and that is done with a sharp chisel.

You want a pattern bit and to make a pattern that fits tightly to the leg, so that you can’t mess up the positioning. Because if you can mess up the positioning, you will mess up the positioning. At least I tend to at least once.

You can do something like Cam does to install the table legs. Instead of using a guide bushing, you can use a pattern/flush trim bit.

I should downvote you, because now all I want to do is watch woodworking videos all day. But, the video is on point and a good idea for the OP. Now, I got some youtoobin to do today.

Yep. A good router table (you can even build one or there are nice ones available) and a jig will do what you need.

I make end up making jigs for every single project that end up getting trashed or repurposed after the project. I take as much time as necessary to build a good jig that sets the boundaries for you and you just execute the cut.

Everything is repeatable with a jig or template.

Is it tapered? Hard to tell in the picture - not that it makes any difference but it being tapered would make it slightly more difficult to do.

The cove at the top and bottom are simple straight up router jobs unless its tapered. The same is true of the reveal at the top and bottom...simple router job or a dado set in a table saw or even a flat face blade in a table saw and a series of cuts.

Is there a deeper recess around the edges of the faces are is it the same depth? Hard to tell in the picture but again only makes it a little harder. If it is not a simple jog and pattern cutting bit will easily do the job....remove about 1/8 of an inch at a time. If you want to save some time drill a series of holes with a forstner bit and remove the material with a router....or remover part of the recess with a circular saw or even a table saw and remove the rest with a router bit. Will be fairly easy to do. Will take some time anyway you do it. If it is tapered it is going to be harder.

Get one of your boys with a CNC to make you a template and then use your plunge router. Solved.
