Yep, if I had a dollar for each time I'd said that, and done that..... well, I could buy some more tools!
I like to double or triple up the thickness of the rear boar right where the saw cuts through, just a bit more insurance to keep my fingers from setting off the brake cartridge in my SawStop
Sometimes when I'm cutting a bunch of small pieces by using a stop block on these sleds, I worry that my hand could wander and forget about that blade coming out of the back of the sled, that's all
