[Milsurplus] Removing beeswax from slug-tuned transformers

[Bob Camp]

Hi

With beeswax a *little* heat goes a long way. If you use a heat gun you 
want to set it so it's putting out warm air and not hot air. You should 
be able to spray your hand for a ten count with the heat gun.  The same 
thing applies to heating with a soldering iron and allen wrench. It's 
better to start out heating the wrench out of the core first. This is 
definitely a go slow and don't apply a lot of force kind of work.

There are several problems you are trying to avoid. One is the obvious 
one of setting stuff on fire. The other is to not hit the core with to 
much heat all at once. Cracked cores are a real pain to adjust. One 
very unusual problem is when the core is *only* held in by the beeswax. 
I have never seen a coil like this, but it's claimed they do exist. If 
so blowing all the wax out isn't a real good idea. I certainly have 
seen coils that have the windings held in place with a glob of beeswax. 
It's probably not a good idea to have the windings fall off the coil 
...

	Enjoy!
