I'm a new member and fairly new to woodworking. I recently acquired my first SS, a 510 with shaper setup and speed increaser. I also got a SS Pro Planer along with the 510.

I want to convert a pile of 1x4 rs pecky cypress to vee-joint tongue and groove for wall panel planks. I have seen several router bits that cut the tongue or the groove at the same time they ease the front surface edge. (This is what I mean by "vee-joint" tongue and groove--so that the joint between each board consists of a vee groove. It would be the same profile as most of the commercially produced tongue and groove you see in lumber stores.) The problem is that I feel a router is not up to the volume I need to produce for this project.

My question is; does anyone know where I can find shaper cutters that produce the desired vee-jointed tongue and groove pattern in one pass? I realize I could cut a conventional tongue or groove and then change cutters and ease each front edge, but that will double the number of passes for each board and add a lot of time.

Any experience or suggestions would be appreciated.

Unless you're only running a small amount of stock, I wouldn't even consider using the shaper cutter method. You only have three or four cutters. The bits can only handle a fairly slow feed rate, and they require periodic resharpening. So where's the time saving? Though more steps are involved, I'd consider simply using the tablesaw, with a suitably tall 'stock support' fence. [perhaps opposing fences on each side, of the stock]. Depending upon the width of the tongue & grooves, two circular saw blades with/without spacers, should do fine; and there are a lot more cutting teeth involved. Alternately, use a dado blade setup. Visualize the cuts to be made, and how you'd need to configure either the circular saw blades or the dado blades, to 'effect' the desired cuts. Final step would be to tilt the table and make the final pass, to form the chamfer and the resultant 'V' groove. My suggestion may involve more setup and passes, but since the larger blades wouldn't be 'laboring', and wouldn't require periodic resharpening, the total time element would, perhaps, be less. Dado blades can be custom made, which would do all necessary cuts, in one pass, [at least on the tongue edge] then a second pass run on the groove edge.
