Thanks! I went to Home Despot and the greeter girl says "Hello, how are you today?" I said "I get to buy POWER TOOLS, it's a guy thing." She said "Yep, it's a guy thing!" So I got this cool Ryobi 4.5" angle grinder with a swivel handle with a nice clamp-on guard for $39. I had one at home and took it to work to replace one that was stolen. And, I got a $12 diamond blade. Ooooo! That works nice and fast! I cut 1/2" all the way around and tap it with a hammer and "Bink" a perfect cut! Thanks guys!
I'll send pix of the patio when it's finished and lit, it's going to be nice and I entertain outside a lot.
(Now for the waterfall and fishpond!)
