[Shop-talk] Anode for compressor

Sounds possible that it'd help.  Why not ensure the connection by drilling a 
brass contact bolt through an end cap and wire it to the anode with a long 
braided wire as Kai suggested ?  Maybe some silicone grease on the contact 
spots to make sure the connection stays good.

I've always scoffed at compressor tank corrosion as I've been lucky and 
never have had a rust problem with my pre-WWII compressor tank.  However, I 
recently got my 1977 2-HP compressor back from an extended loan (22 years). 
It was nearly new when I loaned it out.  When I got it back I dug and 
flushed about 10 double handfuls of black muck out of the tank - all rust. 
And the interior is badly pitted.  I phosphated it to stop the corrosion for 
now, but I'm still not sure I really want to even test it.
