[Elecraft] [K2]...Hot glue toroids to PCB???

[Mike-WE0H]

Building my K2. Does anyone see any issues with using hot glue to glue 
the toroids down to the boards? I've never had issues gluing toroids 
down in my 600 meter projects. Inductance values have never changed from 
no glue to glued down. But with the K2, it just doesn't seem right to 
leave the toroids loose without gluing them to the boards. So what do 
you guys think, glue or no glue?

Many thanks,
Mike
