Set up a guide on the saw to keep it aligned:
Take the planks and run them thru the saw slicing off 3/16" strips. I got 24 strips from each 1" x 8" plank. Infeed and outfeed rollers help with this. The Forrest Woodworker II thin kerf saw blade is awesome and you can feed it thru as fast as you can and get a smooth, smooth cut.
Next you need to mill a cove on one side of each strip and round off the other side so that they all key together. You could do this by running each strip thru two routers. Instead, I set up two routers (one on top, one below) a router table:
Feed the strips thru the two router setup to mill the bead and cove at the same time.
When you are all done you have a bunch of strips and a whole bunch of saw dust (actual size of the sawdust pile is about 4 feet wide by 1 foot tall):
