Rather than making stone-cutter benches permanent fixtures in different bases. I carry a couple of iron bars to make a bench, then deconstruct it when I am done. I like to repair those intact stone towers in the wilderness, put a roof on them, and use them for portal hubs. I just finished doing that in a tower, then took apart the Stone-cutter bench and converted a Troll Cave on the coast of a distant continent into a base using stone. It's on a little peninsula very close to a swamp, and has a deep creek with very steep cliff walls making it an awesome place to safely park and store a longship.
