Sorry to be so vague. Yes, I'm refering to the magnetic base (without the dial indicator). When I turn on the switch, the base holds to my table with 45 pounds of force (2 would be doubly so). If you unscrew the rod from the base you have an attachment point for a wood plate or wood L-bracket that you could affix a featherboard (pre-made plastic or homegrown wood version). The advantage over the griptite is that you would get finer control over placement before locking down and you would also reduce scratching of your nice tablesaw finish. Removing it is also easy, because you don't need a brute force plastic cam lever. Another advantage is that you would have a more traditional feather board design with more fingerlets to hold your board in place.
I did find 1 reference on the web from woodworking tips from an magazine, but the full article (with photos) is not available.
