"How is it done?"
First, let's make one thing perfectly clear, burls do
not come naturally hollow. Usually, you should begin with a piece of wood
that is as solid as possible. The bottom of the piece is glued to a faceplate
and mounted on the lathe. Starting with a slower speed, the exterior shape
of the vesel is turned first. Now the actual hollowing process begins.
First, a half-inch hole is drilled down through the center of the vessel
to act as a depth indicator. Next, a straight square-end scraper is inserted
through the vessel's opening (or neck) to begin removing the interior.
The interior scraping quickly causes a build-up of chips that are removed
with a vacuum hose. After the interior has been rough-hollowed, a hooked-shaped
scraper is used to thin out the side walls beginning at the top of the
vessel and working down to the bottom. A wall-thickness indicator is used
in conjunction with the hooked scraper to gauge thickness. A plastic tip
on the end of the indicator bends while the wall is still thick and when
the tip straightens and no longer touches the exterior of the vessel,
the vessel is down to the desired wall-thickness. Lastly, the vessel is
parted off and the bottom is finish sanded by hand.
