Guest Demonstrator November 2002:
Alan Lacer
Alan resides in River Falls,
WI. He has been a turner for
over twenty-five years. He is
also a teacher, writer, exhibition
coordinator, demonstrator
and was the second president
of the American Association of
Woodturners. His work has
appeared in numerous regional
and national shows and he has
instructed turning in thirty-five
states and four foreign countries
including Japan and Germany.
He has also taught at
the John C. Campbell Folk
School and Arrowmont School
of Crafts.
The demonstration began
with a discussion of the skew
chisel. The secret of excellence in using the tool is to
have it "scary sharp." Alan then discussed the use of
the right angle hook tool for end-grain hollowing. He
makes his own using quality carbon steel. A gouge
with a limiter was then shown and discussed. For the
remainder of the morning demonstration he discussed
the various cuts with the skew chisel ground to seventy
degrees. These cuts include roughing, planing,
peeling, V-cut, shoulder, saucer, pommel and rolling.
The curved skew was discussed. The differences
between straight and curved are quite subtle. A
turner should start with the straight and progress to
the curved. Alan feels that practice with the skew will
enable turners to be more proficient with other
gouges such as the bowl gouge. The straight skew is
easier to sharpen. The side edges of the chisel
should be rounded, especially the short edge side.
The oval profile skew is difficult to grind.
Sharpening was then discussed. Alan uses eight
inch wheels of 60 or 80 grit with a grinder speed of
1750 rpm. He uses a coarse
wheel initially. He uses an angled
grinder platform set at a fixed angle.
To get the chisel "scary
sharp" he uses a cylinder of quality
MDF particle board. This he attached
to the headstock with the
Morse taper. White buffing compound
is applied to the wheel.
Alan hones from the opposite side
of the lathe because you want the
wheel to go away from you -- not
toward you. He rubs the bevel,
not the edge. When the "mud"
comes over the top you are finished.
The honing wheel is about
the same diameter as the grinding
wheel. Alan also uses a fine
grade diamond honing bar. This
achieves sharpness on all four edges -- the two hollow
ground bevels and the two edges to achieve the
"scary sharp" points. He hones frequently and grinds
infrequently after the initial grinding.
The tool rest must have a clean, smooth surface.
This is achieved with a mill file. Alan uses a dead
center and not a spur center. This reduces the severity
of catches. A live center is used in the tailstock.
He sharpens the rim of the dead center and puts
three or four scallops in it to make it more effective
when turning hardwoods
Next, Alan began demonstrating the various cuts
using a piece of fir. A large roughing gouge was used
to take the corners off. The peeling cut was used to
remove wood quickly. This was done with the curved
skew chisel. To plane, Alan uses the short side of the
chisel down. The "sweet spot" of the tool is just
above the short edge point to just past the middle of
the curve. He feels you probably need only two
skews ½ and 1 ¼. He places the tool rest higher
than in bowl turning.
The V-cut was shown to establish detail and to achieve a finishing cut.
Next, the shoulder cut was demonstrated
using the long point of the tool with the edge of the tool as the bevel.
Alan keeps the tool above center. The saucer
cut was done to achieve a concave shape. The skew used as a parting tool
gives a cleaner cut than the actual parting
tool. This is because it does not tear -- it cuts. The pommel cut was
shown after squaring up the piece. A
straight and a curved pommel were formed. This completed
the morning demonstration.
The afternoon session began with a demonstration of the
rolling cut using the curved skew chisel. This is probably
one of the hardest cuts to perform especially when forming
true beads. Alan formed the bead with the short point
of the tool. He then turned two extremely small tops using
the curved skew -- both worked very well.
Next, Alan began a poplar box. He first formed a shoulder
to place in the chuck. The interior of the box was
turned with various tools -- each giving a rough surface.
He then used his right angle hook tool. The shape of the
hook determines the cutting action. The ring tool by Sorby
is also useful in forming the interior of the box. The Termite
tool was then used. This was followed by a ring tool and
finally a tool with a limiter was used on the inside of the
box. All of these tools produced a very smooth interior surface
requiring little to no sanding.
Alan then described how to make a hook tool using 3/8
inch 0 #1 drill rod tool steel. Besides the drill rod he
uses a mill file, a can of olive oil, needle nose pliers and MAPP
gas. He stressed you need the proper tank head for MAPP
cylinders. First the drill rod is ground to shape and the end is
rounded off. He ground the tool on a belt sander. The tool is
placed in a handle for ease and comfort in heating. The tip
was then heated using the torch until red hot. It was then bent
to form the hook shape. The hook was again heated until red
hot and then plunged into the can of olive oil. He then made
an offset hook tool.
It was first bent -- then offset to the right. Both were washed and sanded. The
hook was bent to the left on both tools and the offset to the right. At this
point the tools are in a hardened state. They can be tempered in an oven at 470
to 490 degrees for 30 minutes. They are then air cooled and a bronze color
forms. For demonstration purposes Alan used a propane torch to temper the tools
-- again to the bronze color -- then quenched them in water. They were then
ground to sharpness and honed with the diamond bar. When turning, the flute is
presented at the 9-10 o'clock position. At 11
o'clock you're looking for trouble -- at 12 o'clock you're in trouble.
The demonstration concluded with the turning of a soft maple box. The piece
was placed with the dead center in the headstock and the
live center in the tailstock. It was then rounded with a large
Crown roughing gouge. A tenon was then turned at both ends
of the piece. A coarse hack saw with 18 teeth per inch
was used to separate the lid from the bottom. The lid piece
was then placed in the chuck and the inside of the lid
turned to a tapered shape. A three-eighths inch bowl gouge
was used to initially hollow the lid. The hook tool was
used to finish the surface of the lid interior. A round nosed
scraper was then used to finish the sides of the lid interior.
The bottom of the box was then placed in the chuck. The upper
part of the bottom was turned so that it would
snugly accept the lid. Alan stated that the lid and bottom of
the box should be rough turned one day and finished another
to let the wood change shape if it is going to. The interior
of the bottom was completed using the round nose
scraper -- then the hook tool -- then shear scraped. It was
then parted off and a jam chuck formed on the piece remaining
in the chuck. This was done so that the bottom could be finished.
It was given a concave shape and the box
was completed except for finishing.
Last in the demonstration was the use of the hustler tool -- a large, three foot tool that
was used in the past for forming masts and booms on ships. It has a limiter attached to it. A
small log was placed between centers and the tool produced long, six foot shavings -- quite
impressive. This completed an excellent demonstration. A video tape will be available in
January for further review of Alan's demonstration.--Bob Gunther
