finding true dimensional joists or ripping down lumber
OK..I've searched and searched and cannot find a solution or answer. I'm replacing approx 8 2x8 (true dimension 1880) joists that span 12' in the basement that support the first floor in a balloon framed home. The joists are attached to a 10x10 main beam and the other ends rest directly on the fieldstone foundation. I cannot find true dimension lumber for anywhere near reasonable pricing. The original joists sit back about a foot onto the foundation to support the upstairs floor so notching a 2x10 wouldn't work. Can I purchase 2x10's and cut them down to a true 8 inches? If not where would you recommend finding the proper lumber?
