Tenons on a 6' long board

[AlanS]

Obviously I cannot cut a tenon on a 6' long board on the tablesaw. What kind of jig do I make to do this ACCURATLY with a router?

You could always cut them by hand.

A tenon is roughly the middle third of your stock. So if your stock is 3" x 3" your tenon will be 1"sq. Use a hand saw to remove the waste and trim with chisels.

I've done it on the triton, with extension table, many times. unfortunately you only get to take off about 3mm at a time so its a bit slow, but easier than trying to stand a 6' board up. set the fence for the length of the tennon and just make several passes advancing 3mm or whatever your kerf is at a time

Just clamp a straight edge across the piece, that the base of the router runs against then set the depth required... no real need for a fancy jig for a one-off job.

First, and very important. With a marking gauge, marking knife or utility knife, score the stock where the sholder of the tenon starts. This prevents chip out during the cut.

Use a Rip blade in the table saw. Raise the blade height to the depth of the sholder. Set the fence to the length of the tenon, less the width of the kerf. Hold your 2M board against the miter gauge and nibble away. Yes, it is slow but it does work. The reason for the rip blade (or a true combination blade) is the raker teeth. They will make a flatter cut on the tenon.
