Default Cutting sequence for pool table job.

I've been asked to do a job for a customer who builds pool tables. He would like me to make the legs and curved surfaces that go behind the legs, and run horizontally. The legs are 6 to 8 inches square.

I am thinking of doing the curved cove rails behind the legs as a single piece with a simple 2 rail sweep in Aspire. The vertical legs pieces will need to be cut in pieces and glued up since, the router bits have only so much depth cutting. The photo I have attached shows a fancy corbel type carving, but only the basic shapes will be cut.

If any of you have suggestions how to do this job I would like to have some feed back.

If you don't need any of the ornamental features/reliefs, you can create all you mention with a 2 rail sweep. The corbel face of the leg can be done on 3 sides to get complete coverage or if you don't need that simple scroll, just with some 3D toolpaths. The only thing you really have to worry about on the main face of the corbel part is collet collision. You can get tools up to a 4" cutting length and 6" overall off the shelf.

If I were doing it, I would just scan the parts and go from there. I'd extract the moulding cross section and sweep it & break out each face of the leg for single sided machining - then do the glue up.

The customer provided me with a side layout of the parts he wants cut. The horizontal rails will need to be in two parts. The vertical legs will be CNC cut into 3 pieces then glued up.
Since I have only a certain amount of height on my machine I will need to get creative with a longer router bit to avoid height problems.
