Butternut Bowl Continuedfrom Previous Pageas it sticks to itself even months laterwith no “cold” joint.A quarter on the outer rim givesa sense of scale. Note the whitecenter area where decay has takenhold, leaving many small voids; seeFig #5 close-up.Fig. 4Fig. 5There were a number of optionsat this point. One, I could apply lacquerto both fill the tiny voids and toprovide stiffness to the wood fibersduring the next phase of turning.Two, I could fill this area, and anysmall bug holes, with fine sandingdust and glue. I could use dust thatis whitish from this area, or from adarker area. The results would eithermake the lighter area more apparent,or cause it to blend with the darkerarea. It is a matter of artistic taste.Third, I could scrub in a thin coatingof EZ Poly in its natu- ral light tan,or by adding powdered colors, evenlike red, to show stark contrast.At this point I stopped to pondermy options, and turned attentionto the inside. Another reasonto work the outside and then theinside, in damaged wood like this,is to uncover any more problemareas and determine if they shouldbe dealt with by thinning on theinside vs. the outside of the vessel.Figure #6 shows the inside, withsome cuts having run from edgethrough inner center. And, the startof thinning at the edge is shown.This is where thinning shouldstart as it allows the greater massof wood to exist toward the centerand middle to support the thinningedge. A quarters shows scale.Two EZ Poly filled voids areshown. The rim is undercut usingthe round carbide cutter toolsnow on the market, making suchcuts quite easy without bendingfar across the lathe bed. On largerbowls this sort of rim also providesa better thumb grip when carryingthe filled bowl. Depending on theshape of the outer rim, that areacan become a place for decorativegrooves, gold leafing, etc..Fig. 6After an evening’s reflection Idecided to fill the small voids withEZ Poly, adding sanding dust fromthis vessel. About 1/2 oz. of EZPoly was mixed with a teaspoonfull of light dust, and applied witha putty knife, using small strokesand pressing the mix into thevoids firmly. Figure 8 shows whatit looked like at this point...a bitghastly.Figure 7. Shows my roundcarbide cutter coming up andunder the rim.I could have started sandingafter 2 hours, but waited until nextmorning. 60 grit on a 5” cush- ionedpad, in my drill, cut through the EZPoly easily. When wood began toshow I moved the sander onto moreof the EZ Poly.The next step was touse finer grits andunveil what might bethe final appearance.The next step was to use finergrits and unveil what might be thefinal appearance. Figure 9 showsthis as work in progress. The centerarea has been sanded down to 220grit. You can see the lighter coloredvoids. Two of the black EZ Polypatches have a coating of the lighterEZ Poly. The still unsanded EZ Polyis at top and left sides.The feel of the surface in thewell sanded areas is very smooth.At this point I could finish sandingthe whole outside and, if I like, applythe final finish, like lacquer. Icould also decide to turn and sandthrough the now firmed up decayedareas and see if better wood mightshow. The risk is that the decay willgo all the way through to the inside,Page 12 More Woodturning August 2009
which is probable, leading to greaterproblems or a lost vessel.Figure #10 shows a coat oflacquer applied and buffed with aScotchbrite© pad. This leaves aninteresting effect and would raisediscussion with a potential buyer.A final coat of lacquer followed bybuffed wax is likely. Attention wasnext turned to bringing the insideof this bowl to proper form anddealing with uncovered imperfections.The next evening I had timeto commence hollowing the inside,starting at the rim area, then workinginto the bowl’s depth. Sureenough, as Figure 11 shows, therotted area was found (just beyondthe tool rest). It appeared worsethan on the outside of the bowl!Note the two EZ Poly patches. AsI brought wall thickness to about1/4” I had to be careful in this areaand refill the patched areas.Fig 10Where Turners Turn FirstTo assure even wall thickness, Iadjusted my caliper to the thicknessnear the rim, and then slowly slidthe caliper inward toward the centeruntil I felt resistance due to thickerwood. At that point I made a chalkmark. I continued moving the caliperinward, sensing the thickness,and stopped at about an inch and ahalf, again making a chalk mark. SeeFigure 12. The area between chalkmarks was for the next thinningcuts.
