hi guys,
an odd query perhaps, but here goes anyway,
I am currently carrying out some experimentation in the manufacture and use of Solenoids for potential use in an EDM machine.
my first effort using a home-made solenoid was only partially successful, the mechanics proving to be adequate for the job in hand but over an extended period of usage the heat build up within the solenoid was detrimental to the Perspex spool core (slight melt down) Sooooo!, a rethink is necessary. the cheeks of the spool are of Perspex and were undamaged but the Perspex core was not up to the job. The experts have suggested that a better material would be Delrin or even better PTFE which I intend to try but I pose the question, what if any adhesives will work with these materials - Araldite? Superglue?
I look forward to your thoughts
