Today I got a quote for a single piece of wood for a bench 5" by 22" by 6-7 feet. The only material around that big is black locust, I know even asking is against the prevailing wisdom for benches. But I'm smitten with a one piece top, my only concern is the BL being insane to work with, but then again maybe I don't care? I don't know yet. The BL certainly isn't the cheaper or easier option, but it's one piece. and apparently BL is also very stable, and heavy. Thoughts on this?
