Hi folks-
I'm turning a large vase from SPP, 25 rings about 18x13 finished size. The base is a nice smooth convex curve. I've cut and assembled the rings for rows 1-10, and have started stacking them on the base (I glue up on the lathe using a longworth chuck on the tailstock to align concentrically). Things were going fine until I went to glue up ring 6 to ring 5. Not enough wood on the inside of ring 6 to match the angle and width of ring 5. Dimensions of the rings are matching expected internal/external diameters on my summary and cut sheet, so am I right in assuming the problem is the profile of the curve I'm turning to as I proceed? If so, can I print out a profile to follow as a guide during assembly?
I've just made a new ring to go between 5 and 6, which required jumping the board width up to 2" from 1.3". This seems to fit, but not convinced the rest will follow without problems.
I selected the option to round the board widths in my summary report. This seems like it might be part of the problem, in that I have a lot of wood to turn away.
I usually work from hand drawn plans, and don't have as much wood to cut while turning. I do well by cutting off my segment corners and fairing my curves. This is a first time project with SPP, so if anyone can offer guidance I'd appreciate it. Thanks!
