This is a solid steel plate that mounts to the old blade guard bracket, under the table insert. You must make a zero clearance table insert, I make mine from the 1/2" thick melamine coated phenolic from Highland Hardware in Hotlanta. I wrote the gcode to carve the outer so it fits the table quite snugly, then raise the blade to cut the slot, then take it back to the mill and extend the slot all the way to the rear so the shark fin can rise and fall with the blade. I used a 1/8th inch bit and tried to center it on the slightly narrower cut from the saw blade. This allows me to shim the fin one way or the other and I tend to run it to the right so the work is gently squeezed between it and the rip fence. I can just barely feel the work dragging on the fin as it holds it solidly against the fence behind the blade. I did have to mill the mounting slots on the bottom of the fin about 50 thou deeper because the fin was running a few thou higher than the blade, making it difficult to cut slots on the saw. Now it sets within 1/16" of the blade, but the blade is just enough taller it cuts clearance for the fin now. I haven't had an excuse to take it off since.
