Bad news on my part, epoxy of the core was a failure and will need to be redone. it seems that even though the epoxy has a cure time of 24 hrs it was still not ready when i began to grind and buff it. this is what cause the winding core separation which in turn caused the inductance to plummet. so again i am at square one having to redo the core. this time i will use machinable epoxy that of course will be heat tolerant.
R&D can be a bitch some times and this is just one of them. the core is just fine and when finished will excel in it;s purpose but the failing of the epoxy was not expected.
machinable epoxy will be ordered tonight and i will keep everyone updated as to the status. in the mean time i received a very old variac for the electronic thread that you can see shortly.
