[Amps] Anodised aluminum

[Robert Briggs]

I would like to thank you all for the helpful replies and emails 
regarding using anodised aluminum in amplfier boxes...

The consensus is that it is quite ok to use provided bolts and rivets 
bond clean aluminum surfaces...

The material I obtained (free) is 2mm thick and heavily anodised on both 
sides..The anodising is nearly like a ceramic coating and virtually 
scratch proof....I am going to make a 6 meter GS-35B amplifier using 
this material for the case...It has a really nice satin grey finish..I 
have just made up a special tool to remove the anodising from all the 
drill holes exposing the bare aluminum...

I must tell you, the VHF/SHF fraternity here told me that anodised 
aluminum is a big NO for rf work...It takes me three days to manufacture 
amplifier cases in my workshop so I look forward to the outcome...
