I've made and turned about 15+ bowls now (look at my profile for posts), and probably 20+ other segmented vessels like cups, bowls, vases. The one thing I found out pretty quickly is that the creation of the segments, rings and overall glueup takes probably 90% of the time. The actual turning of the thing you're making doesn't take that long, depending on the size and shape. A few tips: Accuracy in the angles of the segments is crucial. I used to cut these on my table saw thinking my Incra Mitre gauge was fine, and it wasn't. I didn't get great results until I created a segment cutting sled, with adjustable angled boards, and then laser cut wedges at specific angles for the number of wedges per segment, and then I can use those to exactly align to my blade on the table saw. You CAN do it without this, but until I did this, I was constantly dealing with slop gluing up the rings. Make a sled, cut exact angled wedges (or buy some 3d printed ones) and then work on getting more accurate.... https://larrymarley.com/scripts/Segment_Calc_V5/SegcalcV5.phpOne of my favorite sites for creating the exact angle / length / width for my segments. All of my projects have been calculated on Larry's site. Get a ton of rubber bands and these:https://www.amazon.com/dp/B0B12DQSF1?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Rubber bands for smaller rings, band clamps for larger rings. Clamp slowly, on a very flat surface (I took a 4x4 sheet of melamine MDF and cut it into 2x2 sheets and glued 2 together to make a flat, cleanable surface. Clean excess glue off of the segments as you go. You have to have some flat surface to sand the rings on. When I first started I created a 12" Circle that mounted to my lathe and I would stick a 12" disc sandpaper to it and sand my rings. It works but dust was EVERYWHERE. I created a hood that I could attach my dust collector to and that helped, but it wasn't a perfect solution. What WAS a perfect solution was a drum sander. I finally bit the bullet and did this based off of the amount of rings I was creating. This was a game changer for sure, but I know that's a big expense for most people. So - yea. A few things. Start small, make mistakes, learn and keep trying!
