Anti Sieze For Coil Slugs??
 

I finally got the frozen slug out of my pretty new and HARD to find horizontal efficiency coil in my 1964 Zenith 5111. I have a new slug, but I don't want that one to get stuck as it is the last one that I have. Anyway, I am thinking of putting common automotive spark plug thread anti-seize compound on the threads. The form is plastic just for the record.

Would this interfere with the performance of the coil. I would think not, but I feel after all the work it is a question worth asking. Thanks folks!

I'd use some white lithium grease. It's slippery and PLASTIC SAFE which is important.

Chapstick !

Or, Chapstick and a little powder graphite on it....

.

Two good ideas! Thanks folks!

A general rule of the thumb for removing stuck coil slugs in post-war tube-era sets:

On cardboard or plastic coils, dunk a wooden toothpick in kerosene and deposit a small drop on the joint between the slug and the wall. On plastic, it usually will free up the slug in a few minutes. On waxed cardboard or shellacked cardboard coils, it may take from an hour to overnight.

When putting the slugs back in plastic coils, use no lubrication, unless it is very stiff and then use a little Vaseline.

When putting the slugs back in cardboard coils, dry off the slug, and lightly coat the slug with Vaseline.

Caution: Never mix petroleum-based lubricants with lithium-based lubricants.
