oh yeah no the pieces I cut were at a 90 deg to the spindle the toolpath is just a 30 deg slope using a flat endmill so I can use it for the dovetail cutting and for the cut out profile of the piece so I dont have to change tools
I see what your saying about setting up the machine like the jig above but correct me if I am wrong if you did that you would have cut all your square pieces first and then set them up right? so really at that point the cnc might not be any faster than the regular hand held router jig?
and yeah I like the look of the splines I can see that being really hard to do on the cnc machine though as those small pieces would not hold down well even with a vacuum table you would have to us something like a pressure foot to hold them down

Ahh yeah sorry i misunderstood. That works just fine then if your including the dogbones. And yes, you are right that pairing plywood with a chisel may be a bit tricky, but it isnât much material so you may be ok.
Yes, you would have to cut outer dimensions of your pieces to size before setting them up for that cut. If this were a one off project then i would certainly just do them by hand. but if you were planning on making a bunch, then cutting a bunch of pieces to size then just setting up in the cnc and letting it run would be worth it.
As for the splines. You would only have the CNC cut the 45° miters. You would have to cut the slots for the splines either in a tablesaw/router jig or by hand with a dovetail saw/chisel. The actual spline material can just be cut into a bunch of small chunks and set aside. You then just glue them in and cut off the excess then sand.
Here is an example of some I did earlier this year (entirely by hand though).

David Barron (really great woodworker) makes a cool video on using veneer (same thickness as your saw) for splines. They look really neat and you donât have to do any chisel work. Just cut the slot, glue it in. No jigs required.
