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.
- 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.
