A combination gouge (not shown) has a profile that ** is somewhere between the two and can be used for either spindle or bowl turning. the lathe and the operator doesn't remember to reduce the speed setting? If he's quick enough, he can reach for the dial or the power plug and avoid disaster, but if not, he's in the way and becomes target practice. I won't mention names ... but a group of woodturners I know decided to have a contest to see who could turn a bowl the fastest. While that's not necessarily a bad concept, the addition of a high-speed setting caused the first person's bowl to fly off the lathe. Ironically, the guy on the receiving end of this disaster was the same guy who conceived of the contest. I think it took six stitches to stem the flow and repair the damage to his forehead. Always check the speed dial, especially before mounting anything to your lathe. Chuck Envy Here's my theory of why there are so many chucks on the market: when woodturning first became popular, demonstrators toured around, stopping at various local clubs. Each club had a different make and model lathe. In order to be able to easily attach wood to those lathes, the demonstrator invested in a chuck that had a good variety of spindle adapters. The demonstrator attaches a hunk of wood to the lathe to show different cuts, and at some point during his demo, someone asks, "What kind of chuck are you using?" The demonstrator answers the question but doesn't think to tell the attendee why he's using a chuck or that a chuck isn't necessarily the best solution for bowl turning. The rookie turner ends up thinking he needs that particular chuck, so he orders one. His friend, not wanting to be without the latest toy, also buys one. Manufacturers see growing interest in chucks, so they begin manufacturing new and better ones. And so it goes ... we now have plenty to choose from. Woodturning continues on page 30 ...
