Larry Hasiak
October Demonstrator
Larry Hasiak, Tarpon
Springs, Florida was born and
raised in New Hope, Bucks
County, Pennsylvania. He began
turning in 1985. Larry has studied
under many noted turners and
artists including David Ellsworth,
Liam O'Neil, Ray Ferguson, Hap
Sakwa, Bruce Mitchell and Michael
Peterson. He is a member
of the board of directors of the
American Association of Woodturners
and has served as treasurer
and vice-president of that
organization. He has taught on a
regular basis at the John C.
Campbell Folk School since
1997. He has won numerous
awards and his work has been displayed in many
prominent shows.Beginning his demonstration with a discussion
of his techniques and certain tips for turners,
he showed a piece he had turned of Norfolk
Island Pine. The concentric branch knots need to
be placed on the same plane in the lathe. The bark
is quite dark and comes off in sheets. Beneath the
bark is a sticky, spongy layer. The wood spalts easily
by simply placing the log on the ground. Below
each of the concentric branches is a notch on the
down side that shows which direction the branch
grows. The branches face upward so the top of the
tree is at the bottom of the piece. In other words,
the top becomes the bottom and the bottom the
top.
You need to know this in order to take advantage
of the star pattern when turning. The top was
placed in the tailstock live center - the bottom in the
headstock using the spur center. Concentric rings
were grooved on the bottom with the parting tool so
when the faceplate was attached it
would be easily centered. Larry
uses 1 to 1 1/4 stainless steel Phillips
head screws to attach the piece
to the face plate - the more screws
the better. He used a six inch face
plate. He turned the top of the piece
until the knots became evident
around the upper portion of the
piece. The knots consist of hard
wood; and should not show on the
rim of the neck because they may
easily chip off. A deep fluted gouge
was used. The object was to visualize
each of the six knots as
much as possible in the top of the
piece. The top was then parted off
in preparation for hollowing. The
outer shape of the vessel was then developed leaving
a considerable thickness of wood attached to
the face plate. This was done to assure stability of
the piece during the hollowing process. The outer
surface was then cleaned by shear scraping. He
then briefly discussed his sharpening technique using
the Wolverine Jig. Larry then used a 1 1/2 drill
bit to do the initial hollowing of the vessel down to
the bottom. The opening was further defined using
a Henry Taylor gouge ground to between a deep
fluted and a spindle configuration. He began the
hollowing with a Dennis Stuart tool. The cutter used
was a tear drop shape with a slight cutting angle.
The tool rest on his grinder is always set at this
angle. He used a rounded, curved tool rest in conjunction
with his hollowing tool. The angle of the
tool handle rests on the round tool rest which he
prefers. The vessel was then hollowed using the
tear drop shaped cutter. It is important to keep
chips out of the vessel and not let them build up and
trap the tool in the vessel. He then demonstrated
small copper rakes he made out of one-half
inch copper tubing. These are used to remove
chips from the vessel interior. He used compressed
air to aid in chip removal. Larry then
used the straight hollowing tool to develop the
bottom of the vessel. The shoulder of the vessel
was completed using the tear drop shaped
cutter. Larry turns the hollow vessels to balance
them about one-quarter inch wall thickness.
He feels that a little "heft" is OK in a
piece. Calipers were discussed to determine
wall thickness and one of his designs was shown. Depth of the vessel
was then determined so as to avoid going through the bottom. A correction for even this mishap was discussed.
The entire hollowing process should be completed prior to completion of the base.
Vacuum chucking was discussed using stretch plastic tape available from U-Haul It. The plastic seals
the numerous air spaces that prevent adequate suction. He uses hot spot glue on the center pith in the bottom
of the vessel to prevent it from being sucked out by the pump.
Camphor Bowl with Corian Plug. A camphor
bowl with a Corian plug forming the lid started the afternoon
session. The opening of the vessel was trued up
- the vessel removed from the lathe. A waste block
was placed in the chuck, trued-up and the piece of
Corian glued to the block. The Corian was trued-up
using a parting tool and then turned to fit the opening
of the camphor bowl. The parting tool was used at a
negative angle to avoid fracturing the Corian. The top
was notched to fit snugly in the opening. A one inch
hole was cut in the Corian lid using the parting tool. It
was then parted off and glued in place. The Corian
was surfaced and the edges formed. It was then sanded. Finishing with several
coats of clear lacquer is done outside. If a blush occurs then lacquer thinner can be
used to remove it but the thinner should be the same brand. Larry feels that lacquer
is superior to polyurethane.
Christmas ornaments. A 2 1/2 x 6 inch camphor block was used
for the first ornament. It was rounded and a tenon formed on the tailstock
end. The piece was reversed and the tenon placed in the chuck. A second
tenon was then formed at the tailstock end. After truing the piece a rough ball
was then formed. A pencil line was then drawn across the ball so that later it
could be realigned after cutting into two halves. A parting tool was used at an
angle to separate the two halves of the ornament. Each half was hollowed
using a small scraper - then a gouge and were then glued back together by
aligning the pencil indicator mark - each keeping its own tenon. Finial were
turned on both ends of the ornament using a one quarter inch deep fluted
bowl gouge.. The ball was then trued-up with a one-half inch scraper. The
tailstock was removed and abrasive turning done to define the lower finial.
Sanding was done with Korax paper (Eagle Brand). Small grooves were then formed on each side of the
glue line and a stainless steel wire was used to burn in the lines. The ornament was then colored using double
ended pens available at most art stores. When coloring a very slow speed was used. The top of the ornament
was then formed with the gouge, sanded, painted and parted off. A small screw eye was placed in the top of
the ornament. and finished with several coats of lacquer. Larry finished using colored laminated wood for another
Christmas ornament and finally turned a small Christmas bell.
Hasiak continued from page 1s then parted off and glued in place. The Corian
was surfaced and the edges formed. It was then sanded. Finishing with several
coats of clear lacquer is done outside. If a blush occurs then lacquer thinner can be
used to remove it but the thinner should be the same brand. Larry feels that lacquer
is superior to polyurethane.
