Stave Vessel Design & Construction Tom Kenyon May 2012
The Art of Segmented Wood TurningBy Malcolm Tibbetts • 10” is too Tall - looking for about 6” • 6/4 wood required for staves - prefer 4/4
First Prototype • Symmetrically scaled plan to 6” high • Simplified construction • Eliminated veneer layers • Eliminated multi layers splines
Revised Design • Prototype too round • Top out of proportion to the body • Center divider too thick • Created lip for top/body joint • Second prototype looked good
Parts Neck Top Separator Splines Staves Bottom
Stave Cutting Jig Based on Replaceable Throat Sled My Friend!
Stave Cutting Jig First Ten Vessels
Dedicated Segment Cutting Sled Designed to accommodate Bridge City Tool’s Angle Master • Large rear fence opening • Removable segment slide
Vessel Holding Fixture • Used for; • Initial glue up of staves • Initial turning of the base • Final turning of the base • Design from PBS TV show and Malcolm Tibbetts book • Duct tape help donuts slide
Ring Sanding Jig • Shown previously in Show-n-Tell • Descriptive article posted on Segmentedwoodturners.org
Templates • Templates cut out of 1/16” plastic on the laser • Outside only one that proved useful
Production • Production of 20 broken into three groups - 10, 5, and 5 • Manageable number of parts • Doable task - not overwhelming • Assessed mix after each group • Wood combinations that worked or didn’t work • Appropriate mix • Available material • Timeline (best recollection) • Design started late Sep, done by third week of Nov • Lots of time finding material (tops) and making prototypes, jigs, and templates • Four weeks to the first prototype • One to two days to prepare material - almost independent of number of vessels • Two vessels going simultaneously • About a day for each
Top • Top opening drilled after finishing - fits tailstock plug - helps alignment during glue up • Inside finished with shellac
Base/Bottom • Lots spinning ! Slow is OK • Watch out for those bolt ends! • Inside bottom base cut to blend in with bottom plug, also gives reference for turning inside
Turning Base Inside & Outside • Trick is getting a tight fit with top • Inside finished with shellac
Finishing the Vessel Last step is to make plug to center vessel’s top on the jig
All Done ! • Used General Finishes sealer and oil/urethane • Buffed with brown paper sack after a week
