Properly finished bowls never reveal how the turner mounted them. However, traditional methods for reversing a bowl to turn the base involve a lot of fuss and bother. Cole Jaws, for example, require cranking at least 48 hex screws for each use (not to mention the aggravation of having to scrabble in the shavings for dropped screws).

Leslie Longworth must have been aggravated, too, because he did something about it. Two decades ago he conceived an ingenious self-centering scroll chuck that does the reversing job fast and elegantly. Unfortunately, it attracted little interest, perhaps because it appears complicated. His instructions were incomplete, because he was able to write only the first of two intended articles on its construction before passing away.

However, with a little imagination, the first article contains enough information to not only make his chuck but to develop it further.
