I'm making some plant stands which will have legs splayed out at 7.5 degrees from vertical. There are two sets of horizontal rails joined to the legs by mortise and tenon joints. (Each set of rails is an "X" shape, so diagonally opposite pairs of legs are joined by a rail, and the two rails intersect.) Normally when I make (non angled) mortise and tenon joints I cut the tenon shoulders on the table saw, then the cheeks with a tenoning jig on the table saw. The mortises are cut with a mortising attachment on my drill press. Obviously all these steps need to be modified to cut the angled mortises and tenons for this project. The obvious approach seems to be to cut the long shoulders with a miter gauge set at 7.5 degrees, and the short ones with the saw blade tilted at 7.5 degrees. The cheeks are a bit trickier -- I guess I need a jig to hold the rail at 7.5 degrees from vertical on my tenoning jig. And then another jig to hold the legs at 7.5 degress from horizontal on the drill press table to cut the mortises.
Does this sound like the right approach, or is there an easier way to do this?
Thanks for your advice.
