[Shop-talk] Separating copper

[Karl Vacek]

Having been disappointed in every rust penetrant I've ever tried, and never
really believing that any of them actually loosened anything, I just heard
of something else from someone similarly frustrated.

Corrosion X is a product sold for internal corrosion protection of vehicles
and structures.  Really popular for spraying inside aluminum aircraft, into
all the hidden panels, etc. where there's no way to clean or inspect short
of rivet removal and rebuilding.  It's not AFAIK sold as a penetrant for
part removal.  However...

This guy had two really rusty Curtiss OX-5 (used in the WWI Jenny, Waco 10,
etc.) engines he'd just bought.  I mentioned that successful disassembly
looked really iffy, and he immediately smiled and said that where previously
he'd anticipate spending months struggling with disassembly, he didn't
expect to spend more than a few hours on each one after an hour or two with
Corrosion X.  The engines have lots of steel and aluminum parts, with some
brass and copper as well.

He's not a Corrosion-X dealer - he makes custom embroidered shirts, jackets,
caps, etc. to support his antique airplane habit.  In fact, he didn't even
specify which formulation to use - they have several.

Quick question, I have an antique split bamboo fishing rod that is
*suppose* to separate in the middle.  The problem is that they are stuck
solid.

I've tried WD40, and some other lubricants with no luck.  Heat really isn't
an option. 

So, any ideas?  I need to be careful, because I don't want to destroy or
damage the rod.  (I believe the metal tips are either copper)

Thanks.
