This will be a simple fruit compote, though you’d expect to see a real one in glass, I’m following the traditional depression-glass form for this project. To be added will be a footed column of some sort, for an overall height of maybe 12 inches. Anyway, here’s the problem! I’ve encountered a slight gap when constructing the rings, each layer has 24 pieces and there must be a pile-up of minute angular errors. As you can see in picture 1, there is a gap of about 3/32” when the segments are assembled, at the bottom of the pic. Here’s what I did: I assembled the rings into semi-circles into a simple angle-aluminum jig, as seen in this picture: Then, I edge-sanded the semi-circles on my belt sander, so that the segments at either end of the semi-circles became absolutely co-planar. Pic: Knowing that the mating edges would exactly be in alignment, I could then assemble the 2 half-circles together with a minimal glue line. Once dried and face-sanded, they’ll be ready to layer onto the bowl body as seen on the lathe here: This step has solved the problem of mis-matching glue lines and improper gaps in ring glue-ups. By this method, you’re guaranteed two mating 180 degree surfaces for a perfectly fitting joints all around. -- Einstein: "The intuitive mind is a sacred gift, and the rational mind is a faithful servant.
