Guest Demonstrator December 2006:
Alan Leland
Overview:
Alan Leland comes to us from Durham, North
Carolina where he has his home and his studio. He began woodworking in 1975 in
the furniture industry for a company called “This End Up.” As with many other
U.S. based companies, overseas competition forced cutbacks and eventual closing.
Alan then went on his own designing and building his own style of furniture. He
also began woodturning. He has continued in both of these endeavors. He
specializes in traditional and functional turning. His ornaments are very
delicate and flawlessly finished. Alan teaches hands-on classes at his own
studio and for woodturning clubs both in and outside of North Carolina. He has
demonstrated at the American Association of Woodturners Symposiums in Charlotte,
NC, Orlando, FL, and Louisville, KY. His teaching focuses on skills and
techniques. It is geared to spindle turning which he feels lays a good
foundation for any woodturner including those who want to specialize in bowl
turning.
Morning Session:
Alan began his demonstration with his detailed
ornament consisting of a globe, finial (icicle) and cap. He prefers dogwood or
maple burl for the globe and a contrasting hardwood for the icicle and cap. He
usually uses a glue block to hold the globe portion. The glue block was placed
in the chuck, trued up and the glue face side flattened using a spindle gouge.
Alan stressed that the tenon on the glue block should be at about 89 degrees so
that the block seated properly in the chuck. After sanding the surface of the
globe blank that would be attached to the glue block it was glued using thick CA
glue. The tailstock was brought up to press the two surfaces together. A small
bead of glue was applied around the glue joint and then accelerator applied. A
previously glued up block was placed in the chuck in place of the one just
glued. This was then rounded with the spindle-roughing gouge. The diameter of
the globe cylinder was measured (should be 2 to 2 ½ inches). This measurement
was then marked on the cylinder and reduced by one quarter to one third. This
gave a rough estimate of the height of the globe. The center line of the globe
was marked and each half was divided in half. The area between the marked off
globe and the glue block was removed using the beading-parting tool. Edges were
blunted to prevent injury especially when sanding. The edges of the globe were
rounded producing a rough shaped globe. The previously drawn center line was
left for symmetry until the final shaping. The shape of the globe is a flattened
sphere. This permits the cap and the icicle to compliment the curve of the
globe. Any small ridges produced by the gouge were then sanded with the lathe at
a slow speed to prevent overheating of the wood. A dimple was then made on the
bottom of the globe with the skew to facilitate using the drill bit. A Jacobs
Chuck was placed in the tailstock and a five-eighths inch bit used. The depth to
drill was measured and this distance marked on the bit with tape. It is best to
mark the drill about one-eighth inch less than the desired depth in order to
leave some margin of error and thus prevent, or at least lessen, the number of
globes lost. The drill flutes were placed downward to facilitate the removal of
shavings. The tailstock was removed in preparation for hollowing.
Alan uses a series of hollowing tools from
Packard. He grinds each to achieve a degree of negative rake. These are HSS
tools. Alan began with the straight hollowing tool and hollowed as much as he
could. With this straight tool there is minimal torque. Hollowing was done all
the way to the bottom of the drill hole. He then used the 45-degree angle tool,
which permitted him to hollow from the center of the globe to the bottom.
Then
the 80-degree angle tool was used to hollow from the opening of the globe to the
center area. Calipers were used to aid in the measurement of wall thickness.
Once the globe was hollowed the tenon was reduced in size. This was done with
the beading-parting tool. The curve of the globe on the tenon end was refined
and sanded. The entire globe was sanded (Alan goes up to 1500 grit), and then
ScotchBrite pads (gray – then gold) were used to polish the surface. The tenon
was turned to less than five-eighths inch (the diameter of the drill bit used
earlier). The drill was placed back in the Jacobs Chuck and inserted into the
globe to the bottom of the previously drilled hole. It was then backed off
slightly. The lathe was run at a slow speed, the drill advanced, and the globe
parted off by the drill bit. The globe actually rode up the bit so there was no
chance of it flying off. The thickest portion of the globe becomes the top. This
completed the globe portion of the ornament.
The icicle was then turned. A steb center was
placed in the #1 jaws. A wood contrasting in color to the globe was placed
between centers. This piece was roughed into a cylinder with the spindle
roughing gouge. A cone shape was formed with the thinner end toward the
tailstock. A tenon was placed on the headstock end to place into the #1 jaws.
The foot was made three-eighths inch wide and the shoulder slightly undercut to
give the tenon a secure fit in the jaws. The tenon was then placed in the jaws.
The tailstock was not used. The piece was further shaped with the roughing
gouge. Alan formed a fairly thin cone. Distances were marked so that so that the
icicle details could be determined. The tip was shaped using the spindle gouge.
A small tear drop was formed then a tapered tear drop. At this point the turned
portion was sanded. This area would not be returned to because of its thin
dimensions. Further details were formed including two flat plates with a ball
between. Another tear drop was formed. The portion of the icicle adjacent to the
globe was then turned. It was shaped to give it a pleasing appearance that
complimented the shape of the globe. The tenon was turned to fit into the globe
and was checked with calipers. The base of the icicle was undercut to
accommodate the curvature of the top of the globe. Because the upper and lower
portions of the globe had been made relatively flat this undercutting did not
need to be too steep. The undercutting was done from the tenon to the outside.
However, the final cut has to come from the outside to be certain that the outer
edge of the icicle rim is smooth and does not have a ridge. The icicle would
then be sanded (except the distal potion) and parted off. This completed the
icicle.
The cap was then turned from the remaining part of
the icicle blank. Once shaped a tenon was made to fit into the underside of the
globe. It was undercut and sanded. A small pilot hole was made in the center of
the cap so that a small drill could be easily inserted to make the hole for the
eyelet. * The cap was then parted off. This completed the cap and the ornament.
Alan uses Mohawk spray lacquer and applies it with the ornament slowly turning.
Multiple, very light coats are used. It is important to finish the ornament as
soon as possible so that staining of the wood does not occur. This can happen
when particles from the grinder get on one’s hands and then are transferred to
the globe surface. This completed the morning session.
Afternoon Session: Lamp
Alan began his lamp demo by showing how the
laminated blank is glued up. Three pieces of maple were used with purple heart
veneers in between them. The veneers were one-eighth inch thick. Glue is spread
on both sides of the pieces and they are then clamped. Alan uses Titebond-original.

Drilling a lamp blank can be difficult because the
drill bit can wander. This is because of the winter/summer growth rings. To
avoid this Alan places two short pieces of maple in the center of the blank
instead of one long, solid piece. By doing this he only has to drill holes at
each end and not the length of the lamp. He leaves small openings at each end
that he
plugs so that the piece can be placed between centers. Once plugged the
centers at each end are determined. This blank is then set aside so that the
glue can dry and the base is made.
The blank for the base is 12x12x2 inches. A circle
is scribed to determine the actual lamp base size. A router is used to cut a
groove in the underside of the base for the lamp’s electrical cord. The groove
does not go all the way to the center. It stops about one-half inch from the
center. This is so that the groove does not interfere with placing the blank
between centers. A center hole is drilled into the upper surface of the lamp
base. This is made to accept the tenon that will be turned on the base end of
the lamp column. After the tenon hole is drilled another three-eighths
inch hole
is drilled to accept the Talon chuck screw center. Then the band saw is used to
cut out the base. The base is sanded to assure a flat bottom and then placed on
the screw chuck. Be sure at least 3, better 4 or 5, threads grip the base piece.
The tailstock is brought up. Alan does not have a pattern for the base. He
eyeballs a shape that he feels suits the project. A face shield is worn while
turning the base. First the piece is trued up using a side-grind bowl gouge. The
shape is roughed out and it may be refined with a scraper, especially on those
areas where it is not practical to use the bowl gouge. A spindle gouge was used
to produce sharper details but caution is necessary using the spindle gouge,
particularly when nearing end-grain. The area around the center hole for the
tenon was left flat so that the lamp post could sit properly. The tailstock was
removed and the piece sanded. It was taken off the screw chuck and the chuck
removed. A steb center was inserted and the originally glued up lamp post blank
was inserted between centers. The piece needs to be oriented so that the
finished, heaviest portion of the piece is at the headstock end. Also, the more
attractive grain patterns should be oriented to that same end. With large blanks
the corners should be removed with the bandsaw. In this case, with a smaller
blank, they were removed with the roughing gouge.
To get the cleanest cuts
possible lathe speed should be fairly fast because the maple/purple heart woods
are alternating soft/hard. A cone was formed and, using calipers or pre-cut
forms, the diameter of various parts of the lamp were marked out. Once the rough
cone shape was made details were formed such as the bead near the top of the
column. A spindle gouge was used to form the bead. A skew was used
to improve
the surface of the column below and above the bead. The surface of the column
below the bead was checked to insure it was flat. A tenon was then made to fit
the previously drilled hole in the upper side of the base. The shoulder was undercut so that the column sat firmly on the flat surface of the base. A small
bevel was turned on the lower end of the column to produce a shadow line thus
adding to the lamp’s appearance.
It was then sanded up to 1500 grit and polished
with ScotchBrite pads. The ends of the lamp post were drilled to accept the
lamp rod which was passed through the column and into the base. Nuts and washers
were placed on both ends and the bulb fixture placed on top. The wire was
threaded down through the column and along the groove in the base. This could be
covered with felt or cork. This completed the structural formation of the lamp.
Next, Alan turned to coloring. He discussed using
paint, dyes and ink. He mentioned Gary Sanders and his testing various dyes
exposed to the Texas sun. Metalized dyes appear to be the most sun resistant.
Alan showed three lamps – each finished differently: 1.) Paint – dye – ink 2.)
Dye – ink – paint and 3.) Ink – paint – dye. At first they appeared the same but
on closer examination they were different and Alan stated that in the sun the
differences were more dramatic especially the color tones. All were finished
with the same color paints, inks and dyes. This completed an informative
demonstration by an excellent turner. A DVD will be available in the club
library in January 2007.
