Double Bowl Demo (cont’d)Jerry RitterTurning the exterior: With the blank mounted on a screw chuck:1.True the surface which will be the top/open end of the bowl2.Turn the top rim of the bowl to an outer diameter of 5"3.Turn the bowl exterior to a true half sphere with a tenonI used a Vermec sphere jig to turn the exterior. The exterior can also beturned using the template.(Photos of bowl with exterior turned to this stage and with template.)Turning the interior:Reverse the bowl. Use a scroll chuck to hold the tenon.Shape the interior of the bowl to a half-sphere using a template or a spherecutting jig to insure accuracy. The wall thickness of the bowl must beuniform throughout.The wall thickness of the bowl at this point will be the the thickness of the"two bowls”. The wall thickness I used was 3/8”. Each bowl had a 3/16” wallthickness.Turn the interior of the bowl at the rim, to reduce the wall thickness at therim to 1/2 of the original thickness of the bowl wall.The turned edge on the inner side of the bowl rim extends from the rimdownward to a depth equal to the "off-set" or “shift”. My depth was 1/2”.The inside corner of the cut should be crisp and well defined. Use athickness gauge to ensure the rim has a uniform wall thickness.(Photo of photo of bowl, interior template & thickness gauge)Minnesota WoodTurners Association January 2022Continued on next page31

Double Bowl Demo (cont’d)Jerry RitterRemove the tenon: Using Jumbo Jaws or a Longworth type chuck, reversethe bowl and remove the tenon. Use a template to make sure the bottom ofthe bowl follows the "true sphere”.(Photo of exterior template held in place)Offset bowl and remove exterior portion of rim to give the appearanceof an inner bowl sitting at an angle within an exterior bowl.Prepare a jam chuck to accept the exterior of the bowl. Prepare a jig oradapter that can be used in the tail stock mounted live center to press thebowl against the jam chuck.Marking the bowl.(The offset or shift in this example is 1/2 inch.)Looking down at the inside of the bowl, put pencil marks on the rim at 12, 3,6 and 9.On the outside of the bowl, at 12 (the low side of the exterior bowl) draw aline down. At twice the distance of the offset (1”) make a reference markparallel to the rim.121” from rim3961. Place the bowl in the jam chuck.2. Position the tailstock with the modified live center to lightly hold the bowlin place.Minnesota WoodTurners Association January 2022Continued on next page32

Double Bowl Demo (cont’d)Jerry Ritter3. Place tape on the tool rest and make three marks perpendicular to theedge of the tool rest separated by the distance of the offset orshift. (Left mark is L; Center mark is C; Right mark is R)4. Position the tool rest at a level even with the centerline and parallel tothe axis of the lathe.5. Rotate and position the bowl as follows:Mark 6 on the rim is positioned at the R mark on the tool rest;Mark 12 at the L mark on the tool rest;Marks 3 and 9 at the C mark on the tool rest.6. Secure the bowl in the chuck with tape or hot glue so that it does notshift during turning.7. Draw a line around the bowl by holding a pencil at the "L" mark on thetool rest and rotating the bowl by hand.8. Now the bowl is ready for turning.9. Turn the exterior of the bowl one half of the original thickness of thebowl.Minnesota WoodTurners Association January 2022Continued on next page33

Double Bowl Demo (cont’d)Jerry RitterThis step will involve "turning air". For approximately one half of theperimeter of the bowl rim, the wall of the interior bowl will be lower than therim of the exterior wall.Be careful when turning away the outer wall thickness in order to avoidcutting into the wall of the inner bowl. Where the inner bowl wall risesabove the rim of the exterior bowl make the cut crisp and sharp so that itlooks like the two bowls are separate.(Photos showing the bowl on the lathe and off the lathe)Flattened bottom of bowl. Reverse the bowl in the jaw chuck. Adjust thebowl so the rim of the outer bowl is perpendicular to the axis and ways ofthe lathe and then hold secure with a soft nose point in the tail stockmounted live center. Turn a small flat or concave area at the bottom centerof the outer bowl to allow the bowl to sit evenly and avoid rolling or rocking.The small point or area where the soft nose point prevented access whileturning can be carved off and finished by hand.(Photo of the bowl on the lathe for flattening the bottom of the bowl)Minnesota WoodTurners Association January 2022Continued on next page34

This third piece has been entered inAAW exhibition, The Space Between. Our fourth piece is in theworks.When four women get together to work on one project, theresult has to be pure chaos, right? Wrong! Sally Ault, LindaFerber, Ana Lappegard, and Janice Levi have known eachother for over ten years but when Covid kept everyoneseparated and at home, they looked for a way to keepengaged and to stay active. All four women come fromdifferent backgrounds and live in different states stretchedacross the United States, but with the magic of Internet, theymanaged to come together.Minnesota WoodTurners Association January 2022Continued on next page47

Instant Gallery (cont’d)Linda Ferber(cont’d)The ladies regularly teach woodturningclasses, write articles, and demonstratefor various clubs and symposia. Theycontinue to work together to createcollaborative turnings and have nointentions of stopping turning orcollaborating any time soon. Andbecause there are eight hands workingtogether, the women decided to callthemselves “Manos Maravillosas,” or“Marvelous Hands.”The Ties That BindWhen obstacles present themselves, when chasms form between the possible and the impossible, we digdeep within ourselves to find a way to fill that void, to eliminate the space between. Through inner strength,faith, family support, friends, community— the “vines,” the “ties that bind” help us fill the voids that occur inour lives at even the most difficult of times. And the impossible space between becomes possible again.Minnesota WoodTurners Association January 2022Continued on next page48

Instant Gallery (cont’d)I’m giving my son several turnings for his birthday. Heloves to cook so most of them have something to do withfood or the kitchen A simple turning for a cookingaccessory is a mezzaluna board, a cutting boardspecifically for use with a mezzaluna knife. Mezzaluna(half-moon in Italian) is a knife consisting of one or morecurved blades, which is rocked back and forth choppingthe ingredients with each movement. It is typically usedfor mincing herbs or garlic but is used for chopping manyother things, including cheese.Mike RohrerI laminated 2 warped oak boards together and itwas interesting that when I turned through thetop board making the half moon depression, anoptical illusion made it look like the centralportion was cut on a separate radius.Minnesota WoodTurners Association January 2022Continued on next page49

Tips For TurnersMike RohrerWhen your “hook” material on your hook &loop attachment for sandpaper, etc. wearsout it can be a problem and expensive toreplace the part of the tool that the hookportion is part of. I use TurningWood.comfor some types of sandpaper and otheraccessories. They sell very inexpensive“hook” material with “loop” material on theother side, so you use this “temporary”hook material instead of the “permanent”hook material on your tool. I also like theirpads that can go between the temporaryhook material and the permanent.I made my own holes for the suctionholes on my random orbit sander.Minnesota WoodTurners Association January 202252

Tips For TurnersMike RohrerMy arthritic hands are getting a bit shakier week by week.Although I’m managing most things in my shop with someadjustments, daily tasks such as eating lettuce and smallnoodles are becoming more and more difficult.I made some small tongs which work betterthan a fork for much of my eating.

Tips For TurnersHow Can I Safely Reuse an N95 (KN95) Mask?This is a short synopsis of an article from the New York Times If the mask fits properly the CDC recommends that the masks do not need to bediscarded after each time you use it or each day you wear it To disinfect the mask you can store it for at least 72 hours (5-7 days is a goodguideline) in a brown paper bag. Example: have multiple masks on rotation, labelbrown paper bags with the days of the week and place the mask in the appropriatelylabeled bag between uses during the day and at the end of the day. Moisture from your breath will not bother the mask if it dries; if it gets drenched,throw it away. Don’t try to disinfect your used mask with a chemical. Using dry heat or UV light should be used only in medical settings with controlledprotocols. There’s no strict guideline on how long a mask can be used. It depends on fit andtotal exposure. Should you ever throw it away after only 1 use? YES, if you been in a place wherethere was high virus exposure – for instance, if you’ve been interacting with a COVID19 positive person.Minnesota WoodTurners Association January 202254
