This was cut from apiece of wood that a student gave me. It had been a beam in a neighbour's house, then, for several months, an edge of a raised bed in their garden, until he nabbed it in the hope of using it when he buys a lathe. He brought a lump for me to identify and to try out. It wasn't easy to turn; it cut easily enough but its grain tore-out readily and it took a fair amount of sanding to get an even finish. There was a lot of hairline cracks in the first inch-or-so of thickness, hence the scorched rim - not that I need much of an excuse to get the blow-torch out.
12" diameter and 4" deep. Cellulose sanding sealer and microcrystaline wax, with lime wax applied to the open, scorched grain and mostly buffed out again.
C&C always welcome...Les
p.s. .. I'm fairly certain it's Western Hemlock, but am happy to be corrected (Steve!).
