club web page. Contact Loyd Ackerman
- Larry Wendland
announced that he is helping sell his brother-in-law’s woodworking tools. He
passed around a list and had pictures of larger items. Contact Larry if you
are interested.
- Vince Zaccardi had
four wood chisel sets to sell. They were found at the Fine Arts Center and
came originally from Hawk’s Hardware. Vince is asking $11 per set.
New Business
- President Deuermeyer
opened a discussion on the impact of changing the TVW meeting time from 7 to
9 PM to an earlier 6:30 to 8:30 PM. The change has been proposed to benefit
members and presenters who live outside the area by allowing them to return
home at an earlier hour. Look for the subject again on next month’s agenda.
Show and Tell for the February meeting:
-
Jay Hazel brought
a slide show that featured a Mission style headboard that he built
for his daughter. He explained the steps required to go from raw wood to the
finished product and described problems encountered and several innovative
jigs and assembly procedures that he used. He also showed several items that
he has built over the years, including, sets of shelves for his home, lots
of turned Christmas ornaments, a pair of night stands, a computer center, a
walnut mirror frame, Colorado cedar stair rails, and a set of FIFO (first in
first out) pantry boxes for storing can goods.
-
Vince Zaccardi brought a
cherry free-standing shelf unit that he built from Wood magazine plans. The
shelves were finished in linseed oil while the base box and back beam were
sprayed with high-gloss black paint. He also showed pictures he took at the
Appalachian Craft Show.
-
Tom Gillard brought an
end-grain Southern yellow pine cutting board that he built after seeing one
like it at William Sonoma in Nashville. He also described how he modified
6-in sticky-back 60-grit sanding disks for use on a perforated-disk
hook-and-loop sander.
-
Bob Leonard brought “Jim
Bob”, a wood figurine that he carved based on a ceramic original owned by a
friend as his pattern. The piece took Bob a month to carve, and he considers
it to be his best ever head carving, even though Jim Bob has a fuzz under
his nose from a sanding oversight and his lips were chapped from being out
in the weather.
-
Henry Davis brought a
cherry bowl that he recently turned. The small size of the bowl required
removal of four stoppers from his Longworth chuck (four remaining). During
the first attempt to turn the bottom, the bowl moved. He was able to take
the bowl out, tighten the stoppers, re-center the bowl, and achieve a true
bottom turning. The bowl was sanded to 400 grit and finished with Briwax.
-
Bob Reese used a garment
storage bag to make a small-scale version of Loyd’s large vacuum press bag.
He used the smaller bag to inlay a 32-piece cherry and rosewood compass star
into the back of a violin that he is building. He milled the recess for the
1/64th inch thick inlay using a Dremel router base. Parts of the
inlay were temporarily held together with veneer tape and covered in the
press with paper towels and cork shelf liner material. The violin back was
left solid (not hollowed out) during the process to prevent the estimated 10
lb/sq in force from crushing the piece. Bob estimates two months to finish
the violin, and he will bring it in for his first wife to play a tune for
us.
-
Loyd Ackerman brought the
first carving he made using his new CNC router. The rose outline was traced
from a picture and vectorized using VCarvePro software to produce the router
cut instruction file. Loyd pointed out that the CNC system could have been
programmed to mill a decorative border, drill mounting holes, and cut the
piece to final size - - - amazing.
-
Ross Roepke showed an
unfinished oak table he is building for a local benefit auction. His design
was inspired by a recent back cover photo on Fine Woodworking magazine.
-
Stan McKinnon brought an
unfinished box elder demo bowl and the special mandrel attachments required
to turn on a spring pole lathe. He usually turns larger 14-inch bowls from
freshly cut pear wood on shop-built pole lathes similar to the one he
inherited from his granddad. Stan described the construction and operation
of pole lathes, and explained how he makes traditional hook tools in a
home-built two-brick forge. He also brought a copy of a Viking ale cup that
he turned. Ken’s granddad was a chair maker and used pole lathes to turn
chair spindles and other parts. Ken will present a program on pole lathes at
the June TVW meeting.
-
Bob Cantrell brought a
large bowl he turned from a burl cut from a large white poplar tree on his
neighbor’s place. The standing part of the tree, after being struck by
lightning two years ago, was eleven feet tall and five feet in diameter. The
wood is kind of “funny” with lots of knots and wet and dry places
throughout. Bob asked for advice for dealing with wood having the wide
variation of moisture content that he is finding in the bowl blanks.
-
Doug Dulap brought a
peppermill that he turned from cherry and oak segmented rings. He glued a
plug into the hollow assembly for a tenon to attach the lid, but had trouble
getting it in straight. He suggested that a longer plug would have been
easier to align.
-
Mark Ledbetter (member of
TVW for a year) thanked the club for sponsoring the turning bee. Bought
Henry’s lathe and set up in Tom Cowan’s shop. He got frustrated trying to
turn a walnut blank left from the turning bee and didn’t touch a gouge for
several months. He didn’t have the tools that were called for in Loyd’s
segmented bowl workshop, so he started back to bowl turning with a
vengeance. In the few months since then he has turned 118 bowls to various
stages of completion.
-
Mick Knowles brought in
bowls he turned from a maple tree cut in his yard and from a chunk of cherry
that a friend gave him. He also brought two segmented turnings that he
bought in Honduras for $11 and $15.
-
Goeff Roehm brought in
ten wood samples to challenge our identification skills. He asked folks to
examine closely and post their answers on the TVW Forum. Goeff hinted that
eight of the wood species were indigenous and only two were exotic, and he
promised to post the answers on the forum within a few days.
-
Bryan Gordon brought a
drop leaf maple table that he is restoring. The table has been passed down
in his family for several generations and was in pretty bad shape. After
minimal success using Formby’s and other products to remove the seven or
more coats of various paints, he sprayed on air conditioner condenser coil
cleaner and was able to wipe the paint right off. He replaced rails and
slides underneath with well-seasoned poplar and replaced rusted out bolts
and nuts that attached the legs.
Program: Using
Staves (Straight or Tilted) in Segmented Turning
Presented by Loyd Ackerman
- Member/Speaker Loyd
Ackerman was introduced by Vice President Karen Browning.
- Loyd began with a
commercial. “Every single question that came up about the club (during the
meeting) is (answered) either on the website or on the Forum, but you don’t
get it if you don’t look at it.”.
- Loyd explained that
turning stave vessels is one of the several types of segmented turning.
Construction methods can involve open or closed segment rings, straight or
tilted staves, or various combinations. He showed several examples of the
different types of segmented vessels made by himself and others.
- For his
closed-ring segmented vessels, Loyd cuts and glues up sets of
trapezoidal-shaped segments into a series of flat closed rings. He then
sands and glues a stack of rings together and finally turns away the surface
waste to form smooth inside and outside vessel contours.
- The cut angle for a
trapezoidal segment is equal to the number of segments in the ring divided
into 180, e.g., for an sixteen-segment ring the cut angle would be
180/8 = 11.25 degrees.
- The segment length is
equal to the ring diameter multiplied by the tangent of the cut angle, e.g.,
for a 10-inch-diameter sixteen-segment ring the segment length would be 10 x
tan(11.25) = 10 x 0.198912367 =
1.989 inches.
- Loyd uses shop-built
sleds on his table saw to make the precision cuts required for segment
assembly.
- For straight stave
segmented vessels, the cut angle for ripping a stave is calculated the
same way as the cut angle for the trapezoidal segment above, e.g., for an
sixteen-stave tube the cut angle would be
180/80 =
11.25 degrees (the blade angle with the table would be 90 minus 11.25
= 78.75 degrees). Loyd uses a Wixey digital gage to set the table saw
tilt angle to within 0,1 degrees.
- Straight stave width
is computed the same way as the trapezoidal segment length above, e.g., for
a 10-inch-diameter sixteen-stave tube, the stave width would be 10 x
tan(11.25) = 10 x 0.198912367 =
1.989 inches. Stave material is ripped in long strips and cut to final
lengths using a stop block on the table saw.
- Staves are laid edge
to edge and outside down on a flat surface with
the outside (bottom) edges joined with masking tape. The assembly is
rolled up to “dry fit” and check for closure before finally applying lots of
glue and clamping.
- Cutting parts for
tilted stave segmented vessel construction can be significantly more
complicated, since compound cut angles are required. Loyd uses an Incra
miter gauge for setting miter angle to within 0.5 degrees and a Wixey angle
gauge to set bevel angle to 0.1 degrees on the table saw.
- Since the material is
flipped before cutting each tapered stave, it is often desirable to separate
the odd and even numbered pieces into two sets for best grain match. Once
the saw is set up, It is good to make multiple sets anyway.
- Special clamping
fixtures and techniques for clamping the tapered glue-ups were discussed.
Sacrificial glue blocks are often required for flat-angle tapered stave
cones. Loyd has been more successful gluing half of the staves together at a
time rather than gluing them all at once. He then trues up the faces of the
two halves on a disk sander before gluing them together.
- Note 1: Loyd
has placed cut angle tables for making segmented rings and straight staves
on the TVW website, along with compound miter/bevel angle tables for making
tilted staves.
- Note 2: The
TVW Club library has a DVD (#2019) by Loud Ackerman entitled “An
Introduction to Turning Segmented Vessels” The video presents the basics
of calculating, cutting, and gluing for segmented ring vessels. Calculations
for segmented stave vessels are similar, but cutting and glue-up can be much
more complicated if the staves are tilted.
