[CAUT] Key leveling stick??

Hello all!

I figured out a way to make a curved key leveling stick using a table 
saw. Let me "splain":

I built a 50" wooden fixture with a 48" piece of angled aluminum 
fixed at both ends with a slot cut in the middle and toggle clamps on 
each end of the fixture to hold the blank in place. The angled edge 
of the aluminum faces the blade.

The center of the aluminum is pushed towards the saw blade 1 to 2 mm 
and locked in place. I then take a square and straight piece of wood, 
48" x 1 1/2" x 5/16" and attach it to the jig with the toggle clamps, 
squaring it against the bowed out aluminum edge. When the clamps are 
engaged, the outside edge of the stick is under tension and bowed out 
towards the blade, following the contour of the aluminum. I then run 
the jig through the saw blade against the saw fence and cut it 
square. When the tension is released, the stick springs back to its 
original position, leaving you with a perfectly beveled edge on one 
side and a straight edge on the other. Works every time and the 
amount of bevel is adjustable.
