Broken Drum Core Inductor

[SlunkBoy]

I noticed a rattle in my oscilloscope case when I took it out of storage after a move. One of the dumbbell shaped drum core inductors had broken at the point where the shaft meets the bottom disc. The coil has only unraveled a few turns and I think I can salvage it if I work carefully. Assuming I am able to situate everything back where it was, will I compromise any electrical or magnetic properties by supergluing the disc back to the shaft?

Thanks in advance,
Nick

You can glue the core, without significantly altering the properties of the inductor, but i woudn't recommend superglue (by which term I think you mean cyanoacrylate?).
Two-part epoxy is a much better product. If possible, clamp the two core portions lightly in a vice or similar arrangement to minimise the thickness of glue bond.

Thank you very much for the prompt reply, Steerpike. I'll give the epoxy/clamp method a shot.
