...and, what a thing to get distracted by. I rough turned a Black Walnut bowl blank (store-bought), back in April and got it out of its box of shavings yesterday to continue. The outside was shaped and it was still solid, though not round. It was, and is, to be a Lidded Box. So, yesterday, I made it round again, cut the lid off, and turned the inside. All the while, I’m thinking, what a freaking waste of perfectly good wood. It was just a six-inch blank, but, still. A bowl-coring system is called for. Here’s the situation: My lathe is a Shopsmith Mk5, of 1956 vintage. I’m well aware of the popular coring systems, and know how they work. Two posts, one serving as the pivot; the other as the thingy on which the curved blade rests/slides – the blade guide, I presume? I’ve looked all over the internetwebinformationsuperhighway for something that’ll mount to my lathe. I got nothing. Help me?
