It's a delta 46-715. Maybe 25 bowls made from it. Normal use today, and i turned it off to sharpen a tool, and it would never restart again. I tried the obvious things. Power source is there, switch wires are right. My next step is to bypass the switch. Any ideas from you veterans. I know this is not the most highly regarded lathe, but its gotta work till I get a really nice one. (robust).
