The ringmaster tool can cut rings about 11-12 inches diameter, max... and that's if you rough-cut the material it to mostly circular first. My largest lathe-chuck for finishing the project can only handle an object about 8-9 inches diameter.
There's a couple ways around that... I could make larger jaws to attach to my lathe-chuck to handle MAYBE up to 13 inch diameter projects, but that's pretty dicy. Even at the slowest lathe speed, if it's not perfectly balanced it could be disastrous. I could also leave the 1/2" hole in the base of the object to mount the project on the lathe, then glue in a dowl-plug last, and finish around the plug by hand.
The conical shape of this bowl was the result of not doing anything too fancy with the ringmaster tool yet, using its default setting of 1/4-inch walls and having all the layers from uniform thickness material (3/4" boards).
I watched a mfgr-provided video that showed some techniques for mixing various ring sizes for more elaborate bowl and vase shapes, and will get into that before too long... time-permitting.
