Find a steel drill bit which is exactly the same diameter as your saw
blade is thick. Locate it in line with your blade at the rear of the
throat plate and use it to drill a hole. Stick it upside down in the
aforementioned hole and . . .

Ok, sounds reasonable, but what's to stop the drill bit from dropping down
through the hole either due to it's own weight or with the added tablesaw
vibration? With the addition of some type of support mechanism to stop that
happening, it sounds like a viable option.
