Effect of aluminium hangers on galvanised iron/steel balustrade?

In article snipped-for-privacy@4ax.com, Mike Halmarack snipped-for-privacy@gmail.com writes

Speaking from Land Rover Defender experience then if they are galvanised then no and if not galvanised then yes. If you want to be doubly sure then you can get a paste to smear on the contacting surfaces as used in the aircraft industry. I have a tube somewhere in one of my many tins of useful stuff in the garage.

It's possible that it could be both yes and no if the hanger starts to rub away the galvanising. I'll check out the paste. Thanks.

What about the fixings?

That's the whole point - they're meant to be easier to remember mnemonics.

I taught myself the resistor colour code during my very early teens (perhaps just before - it WAS a long time ago now) by simply using the actual colour sequence of "Black, brown, red, orange, yellow, green, blue, violet, grey, white." for the 0 to 9 digit sequence. It was only a decade or so later that I was taught the (NOW!) non PC mnemonic[1] of:

"Black boys rape our young girls but virgins go without." which I was only able to recall with the aid of the (by then) well ingrained colour sequence I'd taught myself years earlier - I was using actual knowledge of the colour code as an aid to remembering a mnemonic intended as an aide mémoire for recalling the colour code sequence!

These days, after over half a century, I'm glad I bothered to learn that non PC mnemonic since it provided a sanity check for my recollection of the colour code sequence when I resumed my interest in DIY electronics projects nearly two years ago after a quarter of a century break - "Use it or lose it!" is ever so applicable in this case.

Another phrase I can't forget (I don't think this is a mnemonic so much as a reminder to be careful) is the "Electrician's Litany" of:

"Ashes to ashes, dust to dust, positive to negative, s*it or bust!"

that I heard one of our EL&P engineers utter. I'd heard it perhaps just two or three times but an amusing enough 'ditty' for me to take the trouble to remember it - I was more easily amused back then.

I've room in my head for only so many 'handy mnemonics'. It seems the phrase, "Less is More" does after all, contain a universal truth beyond that of its general perception as being just an artsy fartsy type's platitude so oft abused by the advertising industry. :-)

That's what I would do with something non-conductive and relatively soft, if only to protect the balustrade from damage.

What fixings? You would use a clamp, rather than risk weakening the rail by drilling it for a bolt.

What about the bolt in the clamp?
