Resources
Quick Starts
Some students may want to start now, by pre-reading background materials. To this end I have posted
a series of articles initially written for The American Woodturner to my webs site:
www.jlrodgers.com. Also this handout can be found at the same site.
Segmented plans and kits developed by Bud Latven are sold through Craft Supplies and Packard Woodworks.
Some of these plans are for more complicated designs, but are a good way to learn about some of the tricks.
Note that each plan contains full scale drawing and are rated from easy to difficult (1 – 5).
Tutorials
Tutorials are also available on line from Kevin Neely (www.turnedwood.com) who has probably taught more
segmented turners that anyone and Verified Software (www.segmentedturning.com)
On the transitional vessels and other materials from this class see by site: www.jlrodgers.com
Cutting sled
In order to accurately cut segments you will require a fixture that cuts the desired angle repeatedly, allows for
segment edge length measurement, and provides safety when cutting smaller pieces. For detailed information
on building a cutting sled download complete instructions for my sled from AAW or one of the others processes
available:

Segmented Project Completion Instructions
This instruction sheet describes the basic steps in constructing a ring segmented vessel. While
projects may vary the work steps will remain basically the same. Some open bowl project will
only require one face plate.
When turning the vessel or bowl concentrate on obtaining the correct shape by referring to your
drawing. Disregard the voids between the rings and concentrate on the curvature; as you approach
the correct shape and diameter the voids will disappear.

o Check for flatness with a straight edge
o Final thickness and ring flatness will be completed after the ring
is glued to the project


Assemble project
o On each of two faceplates, attach a glue block of approximately the diameter of the
foot and one approximately the diameter of the top neck ring to be affixed

Turn sled right side up remove the segment fence
Elongate one of the drilled holes to 1 inch long
Bolt segment fence in place readjusting accurately to 15 degrees
Add toggle clamp to the segment fence approximately 6 inches to the right of the saw
kerf
o Cut a short strip of hardwood with the sled to use as a segment stop
Calibrate sled
o Set TS blade to an accurate 90 degrees vertical with a good straight edge
o Rip several strip of hardwood to 1 inch
o Clamp stop in place with the toggle clamp
o Carefully cut six segment using sled
o Snugly assemble the six pieces against a straight edge and check; there should be no
gap
 If there is a gap on the outside of the semicircle of segments, the angle is too
oblique
 Adjust the segment fence towards the rear of the sled (away from the
operator)to increase the angle
 If the gap on the inside of the semicircle, the angle is too acute
 Adjust the fence rearward (towards the operator) to decrease the angle
o Repeat by cutting another 6 segments and retesting
o When the six segment test appears perfect, cut a set of 12 segments
 Assemble a full ring by clamping the segments together with a hose clamp
 Check for gaps
 Readjust fence as needed to decrease the gaps to zero
o When calibration is complete, screw segment fence firmly in place with several wood
screws on both sides of the saw kerf
Completing the project
o Recut the stop with the newly calibrated sled
o With vernier calipers, set the position of the stop at exactly 2 inches from the rightmost tooth of the saw blade, clamp firmly with the toggle clamp
o At a convenient location on the stop, place a fine line with an ink pen and square
o Align the stick-on measuring tape’s 2 inch mark with the line drawn on the stop
o Stick the measuring tape in place

TRIGONOMETRY FOR SEGMENTED TURNERS
Angle functions are useful in calculating the setup of sleds for specific angles. When accurately
determined the calculations can set the segment fence precisely. The longer the measured line the
more accurate the set up will be. To calculate
the proper
angle you need to use the appropriate trig
function;
here they are:
Sine =Opposite/Hypotenuse
Cosine=Adjacent/Hypotenuse
Tangent
=Opposite/Adjacent

Setting up a new segment fence





Draw a horizontal line across the
width of the sled.
Calculate the distance up the RH
of the sled by using the tangent of
desired angle
Measure up the right hand side of
sled the exact number of inches
your calculation and mark.
Draw a line from that mark to the beginning of the horizontal line.
Align the sled fence to that line for the proper angle.
Example:
12 segments requires a 15º segment cutting angle
Sled with is 24 inches
Tangent 15 degrees x 24 inches = RH length to calculate
0.2679 x 24 inches = 6.43 inches

A zero clearance TS insert is needed Modifying the zero clearance insert with an additional “ramp” to prevent the segments engaging the blade will be an additional aid A segment measuring stop is also required; it should allow segments to fall freely from the TS blade and not allow them to get trapped. Below is one example of how they may appear. For more information and to see videos of use and construction go to: www.Segeasy.com 16

Notes & cautions:





Note that the photographs included in the write up do not necessarily conform to my
latest thinking.
Dimensions for the glue press can be adjusted to meet the maximum ring diameters
that you require
All 2 x 4 sections added to the uprights must be thoroughly screwed into place since
a lot of sheer stress will be applied during operation
One or more cross beams must be added to the initial under framing to provide
support of the mid portion of the press so it won’t flex
If a longer veneer screw in purchased, less (or no) “notches” will be needed
Use KD construction timbers to prevent wood movement and shrinkages due to
drying
The “plastic” surface of the melamine sheet will allow for waxing to prevent glue
form sticking – this will be needed!
Purchase additional; Melamine disks to match the ring sizes you will pres so that they can be stacked to
equalize pressure during the glue

Student Projects
A first project is an open bowl requiring only one faceplate and four rings.
When turning this project be sure to follow the shape of the drawing failure to do so may cause your
base curvature to be too tight and the wall thinness near the base to be very thin. Strive for ¼ inch
wall thickness.

Second and third projects (or what every time will allow) require two faceplates. One half of the
project is assembled on each faceplate – bottom up and top down. Make the division between the top
assembly and bottom assembly at the widest portion of the project – the mechanical center.

Opensegmentconstruction
Open Segment construction is both easier and more involved. Less accuracy of the cuts is required as pieces don’t fit against each other. However the assembly requires a method of positioning the individual pieces at specific angles around the circumference of the “ring.” This is accomplished by positioning fixtures and indexing of the rotation. More details on the three different methods for this style of construction can be found at: http://www.jlrodgers.com/pdf/open‐segment‐woodturning‐1.pdf , http://www.jlrodgers.com/pdf/open‐segment‐woodturning‐2.pdf, and http://www.jlrodgers.com/pdf/open‐
