May 1, 20233 yr Popular Post After practicing on the Dizzy Bowl I and thinking I had the process down pat, I started on Dizzy Bowl II AKA The Wedding Bowl for my nephew and his bride to be. I ordered some bits of wood from Rare Woods and when that came in on 2/6/2023 I was ready to start the new bowl. So on 3/1/2023 I sorted through some wood and picked out what I wanted to start with. I suspect the horse drawn cart in the background was the delay of game for the bowl. I cut up some strips and sanded them flat on both sides on 3/17/2023. Probably a work related delay of game here. I put them in a box and gave them to my wife to pick the color pattern out. Next up the glue up screw up... JT Edited May 1, 20233 yr by jthornton
May 2, 20233 yr Author Popular Post After my wife sorted out the color sequence I glued them up. Then I cleaned up the slabs only to discover that two parts were in the wrong place and spoiled the pattern. Should have been wide to wide and narrow to narrow but we both missed that. Here you can see I've fixed one and one to go. What I did was cut out the wide strip and replace it with a narrow strip. Here I have the slabs re-sawn into flats and sanded down to the same thickness. I did loose one flat due to squaring up after each repair... Next up cutting the rings on the circle jig. JT
May 3, 20233 yr Author Popular Post I made a circle cutting jig for the bandsaw because cutting them by hand is not ideal. Test cut on some scrap The jig uses a bit of T track with a 1/8" pin and a T bolt and locking knob on the bottom and a positive stop for the sled. Cutting the rings... I added a tab to each one because the center is off on one side. All the ring halves are cut out and labeled. JT
May 3, 20233 yr Popular Post Nice idea. I have seen people use the RingMaster for this task. Their rings were tapered and close enough in size to finish up the bowl with sand paper after gluing.
May 6, 20233 yr Author I started on the wenge base and the plan was to finish it and chuck it on the ID... more about that plan later. JT
May 6, 20233 yr Author Popular Post After getting all the rings cut out I started to glue them together using a bit of wax paper and a flat board and a steel weight. I used blue tape to hold the halves together the folded it open and applied the glue. Most rings the glue joint came out perfect. In this photo you can see the bottom ring that was too short to make a full circle because I forgot that I had to waste every other piece... the replacement is being glued up. Gluing up the rings More gluing rings up. JT Edited May 6, 20233 yr by jthornton
May 7, 20233 yr Author Cutting the segments for the bottom inside of the bowl. Hindsight being 20-20 I should have made the wenge a bit wider... because of the pattern I have to toss every other wedge. Finished segment ring. Glued up. All stacked up for a visual. Next up making the engraved medallion. JT
May 7, 20233 yr Author Popular Post Engraving the bottom of the bowl... or how I learned to love the bomb. My first thought was to engrave the bottom of the bowl but the wenge with soft/hard wood didn't engrave very cleanly. Not happy with that I decided to make a brass medallion and screw that into the bottom of the bowl. My first attempt was less than optional. Facing off some brass stock. First attempt at engraving was a failure... couldn't get the stock perpendicular to the spindle due to the OD not being perfectly round. Ok, I thought I'd use my 5-C collet holder to hold a chunk of brass and that will be easy to align. The max on a 5-C is 1" or so. I turned down the back side to fit the collet. Then with the chunk in the colllet faced off the top. I did a test engrave with a different setup (v-carve this time) on some oak. Happy with that I engraved the brass. Then Painted the letters and drilled holes for the screws. Last I made sure the recess was the correct size for the medallion, the dental floss was to make sure I could get it out if a bit tight. I did refinish the letters and seal it before attaching to the bowl. End of metal working! Next up gluing up the rings. JT
May 9, 20233 yr Author On to the glue up... Gluing up the bottom inside of the bowl. I switched from using hot glue to blue tape and a tongue depressor sharpened up a bit to push the tape right into the corner. This held well and was much easier to remove than hot glue which tears up the glue up disk surface. All the rings are glued up and ready to assemble on the bowl. The bottom and first ring. Because the sides were not exactly identical I put match marks on the top of each ring which made it easier to index them at glue up. Adding more rings. View of the inside, you can see the pattern start to develop. JT
May 9, 20232 yr Author Thanks, I wanted something a bit more interesting than what I did on the practice bowl. JT
May 10, 20232 yr Author Glue up disk got too small so I had to make a new one. Last ring! Turning a Dizzy Bowl does make some interesting chips... JT
May 10, 20232 yr Author Gluing up the top ring with 24 segments I did them in pairs then glued the pairs together then glued them into half rings but somewhere along the way the segments got a tiny bit off and the halves were not exactly flat so I put a spacer between the fence and using double stick tape stuck the half ring to the plywood which had parallel sides. Then I took a tiny skim cut to get the ends square.] Now the half rings had a perfect glue joint. I found that using this method is far more accurate and less prone to mistakes than anything I've tried before. Finally go the top ring glued on the bowl. Next up turning the bowl. JT
May 10, 20232 yr Wow. I’m taking my time reading the descriptions and looking at the pictures, and i’m overwhelmed with the process.

May 14, 20232 yr Author Final sanding of the Dizzy Bowl and due to an issue with the wenge being a bit soft I had to switch to holding the bowl with external jaws. I started sanding with 40 grit for some final shaping because the glue joints being harder than the wood made it impossible to use cutting tools. I went all the way up to 2500 grit a few times restarting at 80 grit if I noticed a scratch in the bowl. JT Edited May 14, 20232 yr by jthornton fix image names
