..I should add, I'm not using double-sided tape or superglued back-to-back masking tape because they'd like mess with my tolerances.

I have a mini Taig lathe ,I have seen many time people attach at the lathe's chuck a rod,truen it and the glue the part they want to machine on the shaft with CA glue. After they finish the machining they use heat to melt cyanoacrylic glue and detached the parts.
Maybe you can do something like that.
