"Epoxy won't set up...it's 2-part & doesn't start setting until you combine them"
Correct...but I'd need a big batch all mixed up standing by; no time to keep mixing it up. But with a two hour cure time, that would be plenty of time to do the whole job.
I'll probably stick with the steel bands...just use two around the "equator". I had other issues that was preventing the slices from "closing" in a few places (I'd used screws (sticking up ~1/16" to 1/8") at the base of the assembly jig to "shim" a few of the slices that were slightly undersized in North/South pole length up/down. This was a terrible idea and the slices were hanging up on these shim screw heads. Should have either done more slices (the undersized ones were from very early builds wherein the jig I was using was not quite "perfect" yet). But I got impatient. Normally the force from one of the steel bands I'm using would have been adequate to squeeze all the slices together (and it did in the "dry run" BEFORE I added the shim screws). Good news is I can fix the few slices that are slightly out of place with plastic wood fill on the few low places and a bit more sanding. Also the few small joint gaps around the equator that did not 100% close...some of which will be cut out anyway with the driver holes, some I'll seal with either epoxy or Gorilla glue. They are only about 1/32" wide and are closed on the interior surface anyway. I know, TMI! Lessons learned from the 1st time.... I'm sure the next one will be a piece of cake! Thanks for all the helpful suggestions! Pics to follow later.- Ed
