Kreg - I'm glad you added safety glasses. I don't do anything without them any longer.
One of the worst eye injuries I sustained was when trying to light a pilot light on a water heater. I had opened the garage or something, and a gust of wind came up as I was lighting the pilot. The gust of wind blew through the heater vent, and blew a tiny piece of rust or metal into my eye. It became very difficult to see, and I had to go to the eye doctor to have it removed. But that wasn't the worst part. I had to go back to the eye doctor almost every day for at least two weeks so they could look at the tiny scar the metal produced, and try to pick out any remaining pieces, rust particles, etc. Going to the eye doctor so frequently was such a hassle that I never want to experience it again. I wear safety glasses for ANYTHING I do in the garage.
A question about the built ins - When you cut the parts, how square is square enough?
