Basic Segmented Turning

Design

• Unlike normal wood turning you will need to plan your design

to build your vessel.

– Watch YouTube for design ring ideas. Very few give you the how to build the vessel.

• Below is a couple of the websites I’ve found that maybe useful

to the beginners like myself

– Woodturnerspro.com – Segmentedturning.com – Turnedwood.com

Design

• Commercial Software

– Segmenting Software (All built to use on a Windows computer

(A MAC must have the windows installed for it to work)

• Lloyd Johnson’s Woodturners Pro software (You can

purchase either a package for $135 or individual programs from $49 to $79 ea)

– Get access to working groups to get questions answered as well

• Bill Kandler – Segmented Turning software at a cost of

$40.00. This is a very good site to obtain ideas and free plans.

• Kevin’s Woodturnings – Can be used with an iPhone, iPad,

Windows or MAC at a cost of $15.00

• No free plans on website- Several YouTube Videos

Bill Kander Products

Website provides plans and general information

use to design my projects

– Woodturners Pro – Segmented Pro – Lamination Pro

What’s required topics

• Cutting jig

– Commercial – Home made

• Types of clamps for gluing up procedures for rings/staves

– Segmented rings – Stave Bowl segments – Design rings

Segment Cutting Jig’s

• Commercial sleds

– Table Saw Crosscut sled - $169.00 & Drop off sled $39.00 – Incra Meter Sled – From $130.00 to $329.00 or Incra table saw gauge

• Home made sleds (Just a couple of sites along with

the one I will provide on a disk) – Websites for sled

Glue up procedures/Clamps for Segmented Turnings

• Segmented turning

– Units are cut at correct angle for the amount of segments required for each ring.

• I’ve seen videos where there is a commercial jig (Stomper)

that uses pegs and rubber bands.

– I use duct clamps and join them together to get the correct size for each ring.

– After rings are assembled I use a press to glue up the rings and base (I use a glue block on the base)

• Some videos show gluing up all rings

– I don’t like to put more than the bottom disk and two other together as this makes it easier to work the bottom of the bowl

• r turning

General Tips

• Segmented Bowls

– After cutting your segments you will need to dry fit them by using a duct clamp/clamps

• If the cut is off a little bit it will leave a space where

they do not meet

– Glue up half of the segments and use a dowel in between each half and finish your glue up with the clamps » Once this is done you will need to sand the ends flat so they will match up

Glue up procedures/Clamps for Stave Bowl Turnings

• Stave Bowls are cut with the two angles to

develop the stave according to your design plan

– Once the staves are cut, I look at them to determine a pattern of the wood

• Take half of them and use duct take to put them

together with the largest half of the stave on top.

• You can just glue up as cut or add a design element in

between each stave

• Use rubberbands stretched from corner to corner to

hold in place as a clamp

Glue up procedures/Clamps

– After the two sides are dry you remove the tape and glue the two sides together

• To glue together, you use a hot glue gun and add hold

down blocks on each side, then you will use rubber bands as clamps to assemble the two sides

• After the two sides are assembled you will hot glue the

bowl to a disk that has some type of tenant for your chuck and turn off the bottom to add the base

• Next depending on your design you will add a

segmented ring to the top for a rim

Getting your rings/segments flat

• Commercial units

– A belt sander (either oscillating or stationary) – A drum sander

• Home made sanding disks

– Cut a disk that will fit your lathe swing and add 60

• r 80 grit sand paper. (Harbor Freight or Home

Depot has larger sandpaper disks) – Sanding Board using a belt sander belt with 60 or 80 grit attached is used to ensure a flat surface is completed in order to add the next ring

General Tips

• If possible use a board for two bowls

– Using this method you will use every other stave to make your bowl and it will give you matching grain – I normally use 12 segments/staves and keep the slope between 30 and 45 degrees (a chart is in the reference folder being provided)

• Saw setup

– Set the miter angle on the sled with a protractor (if using a non commercial jig) – Next dial in the blade angle using your bowl design cutsheet and cut a test side of the bowl to make sure the setup is correct against a flat

• surface. If you have a toe up or down “ONLY ADJUST THE BLADE

ANGLE AND DON’T TOUCH THE MITER ANGLE IN SMALL INCREMENTS
