My TS is a Delta 36-600, the original guard is better than nothing but thats all, it does prevent kickback, that is a plus.
Bought plans for an overhead guard/collector, took care building it and found out I had wasted time and money.
Bought a 1 hp dust collector, closed the bottom of the saw, it helps with the dust but does nothing for blade protection naturally.
Lee is building me a shark guard, hopefully get it about mid August, still got all the digits and only have had one kickback problem, ripping a 2 x 4 in half, about the time I finished the cut the saw kicked one half of it out the door of the shop and stuck in the side of the house about 25 feet away. Don't know if you'd call me nervous now or just extra cautious....
I got lost in thought. it was unfamiliar territory.
