Basic Segmented Turning Tony Duarte 27 August 2019
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
Lloyd Johnson Products • No free plans on website- Several YouTube Videos
Bill Kander Products Website provides plans and general information on building segmented pieces. Did not see anything on stave bowls

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 • https://www.instructables.com/id/Simple-Sled-for- Perfect-Segmented-Bowls/ • Wedgie Sled: http://segeasy.com/index.html
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 or 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 or 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
