Jim explained the dimensional requirements for glued up bowl in general
There were examples of segmented and open segmented bowls on display
Jim had a nice display with the basic glue up subassemblies shown
Precision makes it work so a good cutting jig is very important
At the lathe, Jim starts with a substrate mounted in the chuck
If your lathe doesn't include indexing, a homemade indexing system works well
He illustrates the indexing and gluing for an open segment bowl blank
Open segmenting glue up is a matter of following the sequence
A better look at the first layer of an open segmented glue up
A great demo with the crowd staying to the very end
For standard glue ups, Jim does them in halfs, trues each half, and will next assemble both halves
Completed rings are assembled into "stacks" to build the bowl blank
