Thanks guys.
Steve, when we pulled down the ceiling in the dining room, we found the beautiful hand-hewn beams in the living room didn't extend all the way to the back of the house. It was built in 1850, and the last 6 feet or so had half-round beams with the bark still on them... Not exactly the look we were going for. So when we were getting ready to re-frame the drywall ceiling, a coworker offered three 24' 8x6 beams from an 1800 era cape he owns. He needed to open up a wall and reframed the second floor. While it killed me to cut them to length, we were able to get enough to add those beams just below the existing framing and fill between. And the table was built from my father's old rough-sawn staging planks. He put it together after we mentioned wanting a harvest table in the new dining room. It's pretty cool to have that history in the table, and it fits the space perfectly.
