I am familiar with Alodine. It was used by the 100s of gallons of the liquid
version to passivate the aluminum in the products produced by my former employer.
We also had the facilities to do this and other plating in our engineering
shop. You can see some of my personal handiwork here: http:
A quick note on a protective coating for aluminium:
You might like to look at Alocrom 1200 (Alodine 1200 outside Europe) which
can be hand-applied to preserve and protect aluminium from corrosion,
retaining its conductivity. I used it for many years in industrial and
military applications,

start to play. The beam is at 15
Ray,
I made a 40M rotary dipole and followed Force 12's Tornado loading coil
design. They issued a study
on the evolution of their loading coils from Tom Schiller's original
design. They first went to a smaller diameter (less efficient) coil and
later back to a larger diameter final version
