I have a 79" rough opening and a stock 81.5" metal entry door to install in it. It's a standard 30" Masonite six panel door I picked up at HD. I can't make the RO higher because I'd be cutting into a header supporting perpendicular floor joists above it.
I have the jambs and door all marked and ready for cutting. I figure my 7.5" circular saw will do the job on the door bottom if I set up a fence with some c-clamps and a straightedge, but not sure what type of blade to use for this application. Any ideas?
Thanks
