Finally got this guy done. It's a 6' slab of 5 1/2 thick red oak. Took me a while to wrangle it into shape, but I'm pretty excited to get to work on it. I'd be happy to post more info and photos of the process here if anyone is interested. Alternatively, there's a lot of it on Instagram at #crowworkswood or #crowroubo if you like. The slab is from Leslie Caudle in Booneville, NC (firstname.lastname@example.org). He sells a 'Roubo kit' which gets you the rough lumber to start with. Hardware is Benchcrafted and holdfasts are the 1" ductile iron beasts from Crucible Tools.
