5 Before You Get Started Power tools that I used: Lathe Band saw Table saw Planer Jointer Drum sander Belt sander Disc sander Dust collector Hand tools that I used: Caliper 18 ruler Wood clamps Compass Self made jigs Wedge sled Sacrificial sanding plates Push block Ring press Centering jig

6 Things to consider Use only scrapers and scews because the majority of your bowl will consist of end-grains. Because the bowl will be end-grain if you do not have a multidirectional lathe you will not be able to sand the bowl completely smooth. The nap of the grain will cause the bowl to feel smooth from one direction and rough from the other. Do not attempt to turn down any part of the bowl until all the segments are added. If you turn each ring to thickness as you assemble the bowl, the thin base of the bowl may not sustain the weight of the unfinished section of the bowl. I speak from experience! By taking the time to glue the rings one at a time, and by using a centering jig, you will ensure all the rings are centered (the more rings you have the more important this is). I use Titebond I, or II aliphatic glue. I can glue a ring and in one hour return to the lathe, round, and flatten the ring and glue another ring onto the bowl.

7 Designing your dizzy bowl Dizzy bowls are time consuming and tedious projects. Do not get in a hurry. Determine the diameter and depth of your bowl. Anticipate how many rings you will need to construct. Draw your bowl to scale including all the rings at correct dimensions. Select the different types of wood you will be using. The thinner your strips are the more spectacular your bowl will be.

8 Why draw your dizzy bowl to scale? You can visualize how large the bowl will be. You can determine the thickness of all your rings. You can determine how many rings you will need. You can label your rings on paper before you label your boards. You will have the measurements to all your rings. By drawing a line down the middle of your bowl you can use your drawing to set your compass. This saves a lot of time. You can determine the diameter of you rings in order to prevent wasted wood.

9 Drawing out your dizzy bowl

10 Selecting and rough cutting your wood For rough cut selections Cut all pieces to same length Cut all pieces to same thickness Preferably 2 thick or more. Width is not important at this point

11 Cutting your wood to desired thickness

12 Cutting your wood to desired thickness

13 Bi-symmetrical construction

14 Gluing your pieces

15 Gluing your pieces Use Caliper clamps to prevent wood strips from slipping out of place

16 Glued and finished slabs

18 Re-sawing the slabs

19 Re-sawing the slabs I re-sawed the Slabs to 3/16 and drum sanded them down to 1/8

20 Re-sawing the slabs Slabs are smoothed and thickness set with my drum sander

21 Drawing your rings Twelve boards, Twenty-four halves. All are taped in the back. After the rings are drawn the halves are separated and cut on the band saw.

22 Marking your rings Only outer diameter of rings are drawn and cut. This allows for maximum width

23 Cut rings Because the rings Were 1 in width, I was able to cut two sets of rings and construct two Bowls instead of one.

24 Dry stacking the rings

25 Making your pattern The dizzy pattern is created by turning each successive ring clockwise. Also every ring must be turned the same distance and in the same direction.

26 Ring Overlap After splitting the rings, each set of rings were now 7/16 in width. When the rings were stacked this allowed for a 5/16 overlap. Since I was stacking 36 rings, I had to make sure each ring was centered. From top to bottom, my combined margin for error was only 1/8.

27 Assembly of bowl

Gluing the rings Each ring is only 1/8 thick and is comprised of dozens of narrow strips of wood. This makes them very fragile and flexible. So, if you drop one it will break.

28 Gluing the rings Each ring is only 1/8 thick and is comprised of dozens of narrow strips of wood. This makes them very fragile and flexible. So, if you drop one it will break. Also, they tend to warp when pressed together. For this reason. I first glue them in pairs. The staggered rings create a stronger and more rigid ring. This makes them less likely to break, or warp. This also allows you perform half your gluing at one time making for quicker assembly.

29 Using a Ring Press A ring press applies consistent pressure over entire ring. Use extreme caution when gluing more than two rings. They tend to slip! My Method: Glue two rings and press for five minutes. Start with widest rings. During this time glue two more ring, lift the press, lay paper between the two sets of pressed rings and press. Glue two more rings and continue process. Note: I glued the rings in pairs on the press. I took the pared rings and glued them in place on the lathe using my centering jig.

30 My high tech centering jig Centering the rings

Centering the rings Remove bowl from chuck and place upright. Dry fit the next ring and turn it to its proper location. Glue ring and press into place. Gently clamp bowl back into chuck.

31 Centering the rings Remove bowl from chuck and place upright. Dry fit the next ring and turn it to its proper location. Glue ring and press into place. Gently clamp bowl back into chuck. Center ring with centering jig. Make sure ring is still turned in proper place. Press the ring onto the bowl with centering jig. Wait at least one hour. Round out new ring with scraper. Make sure the flat surface of the ring is square and flat. Get next ring and repeat previous steps. Continue until all the rings are glued onto the bowl.

32 Flattening the face of the ring

33 Adding the rim, or last ring Both the base and the rim were made with Wenge

Sand with 150, 240, 320, 400, and 600 grit. 5.

34 1. Use scraper to smooth bowl. Final touches 2. Use caliper to gauge thickness. 3. Scrape bowl down to desired thickness. 4. Sand with 150, 240, 320, 400, and 600 grit. 5. Sand with 1500, 1800, 2400, 3200 grit micromesh. 6. Finish with a clear gloss. 7. Cut off of sacrificial block. 8. Enjoy your bowl.
