My Craftsman saw has pictures and a chart in the instruction book for crown molding, i.e. if you want the inside of this corner, set this to X degrees and that to XX degrees.
I got to have someone come over this weekend and dig up the front of our house to figure out why the sewer was running out from underneath the front patio. There was a clog, but apparently everything has settled enough over the 50 years since the house was built that the lateral has a belly in it. The clog was bad enough that everything was coming out the joint where the belly way. They cleared the clog as a temporary Band-Aid and we'll have to have them come out and do a more permanent fix once the weather improves. One fortunate thing it that, even though we have a full basement, the sewer line is a high line (elevated about 5-ft high where it exits the basement) so it's only about 3-ft deep. When the nimrods built the house, they also went out about 8-ft and then put in a 90....who puts a 90 in a sewer lateral?
