Sorge Natural Edge Winged Vase
Mike Sorge ~ SML Demo

1. Preparing the timber for the lathe.

  • Whole log section, about 5” inches longer than diameter.
  • Cut a thin flat edge off one side.
  • With flat side down, band-saw into a round a few inches larger than diameter.
  • Use drill-press to clear bark and attach drive center.

2. Balancing timber on lathe.

  • Using tail stock w/ revolving center, set drive center/timber in lathe spindle.
  • Balance top edge of wings.
  • Balance side edge of vase bark.
  • Snug tail stock.

3. Turning outside of Natural Edge Winged Vase.

  • True timber.
  • Shape wings from top down & vase from both directions.
  • Shape vase by determining bark at widest point of vase.
  • Create tenon to be foot of finished vase.

4. Using Super Thin/Fast CA Glue, glue cambrian layer, bark, pith, & other weak spots.

5. Hollowing out inside of Natural Edge Winged Vase.

  • Reverse item and mount in chuck to carve out inside to match outside shape.
  • Begin by removing center of bark and work towards wings.
  • When near wings, with fresh sharp edged bowl gauge, cut wings to desired thickness to match shape, make final cut and do not come back and cut further.
  • Hollow out more inside material clearing material close to inside upper vase edge.
  • Make final cuts using both “push-cuts” and “sheer-cuts”. Maintain same thickness.
  • Hollow out more inside material close to inside lower vase edge.
  • Make final cuts using “push-cuts”. Maintain same thickness.
  • Finish hollowing out remaining material and make final cuts at inside base without going too deep and through bottom.

6. Glue inside bark, pith area and any other weak spots.

7. Sanding

  • Finish steps 1-6 above before sanding.
  • Using low grit (80-100) 2” wavy sanding disc, (2” provides optimum control for bark sanding), carefully sand bark and other glued areas using free hand to support bark edge. Note: short angle sanding drills like the Makita are best.
  • If larger vase, after using 2” for initial bark sanding, can begin using 3” wavy discs. Using low grit, totally remove all bowl gauge lines before progressing.
  • Progress through each grit sanding bark carefully up to 600 grit.

8. Turning tenon into the foot/base & sand foot/base:

  • Reverse item and “jam” chuck using revolving tail center.
  • Following curve of lower vase, turn away tenon using push cut and slightly concave bottom.
  • Note: after a week or two of drying the bowl will warp into a slight oval which will also warp the bottom of the foot/base causing the item to “rock”, after which you will need to level/smooth out the foot one last time.

9. Finishing. Since this is an “art” item (not “utilitarian”), Mike finishes with a combination of varnish and oil, like the “clear” Wadco Oil, which soaks into and hardens in the wood. Then after drying, Mike uses the Beal Buffing System for a beautiful sheen.
