Rusty: As Bj says, 1/16th per full turn is just right. Think more than panels. I use mine to make sliding dovetails, edge jointing, etc, etc. Mine uses two threaded rods instead of one(at each end)hence, if you leave one end locked & turn only one threaded rod, the adjustment is half that of a single rod full turn ie: 1/32nd. For sliding dovetails this can be important. Namely 1/2 turn = 1/64th, a quarter turn = 1/128th. Longest sliding dovetail I have made so far has been 42" long. An excellent breadboard attachment. I didn't note a dust collection port ? I presume that there is one ?
