My folks cut down a birch in their front yard a couple weeks ago and saved me a 5-foot length of the trunk. Craigslist helped me find “Tom the Sawyer”, about 20 minutes from the office. Made an appointment and stopped by this morning. Thirty minutes later I had three 12/4 slabs approximately 11 inches wide and 5 feet long…...pretty cool! Now I just have to let it dry, and I think I will try my hand at flattening via hand planes. Not sure what to do with the lumber just yet, but was thinking a natural edge bench seat with through-mortise/tenon joinery.
