Cleaning the lower instrument bowls - Revs & Speedo
McCabe-Thiele (Ted):
As I have recently received my restored clocks back from Peter Horton I decided to see if I can spruce up the lower housings - I believe they are some sort of stainless steel.
Although you can't see much of the undersides when in place mine seem full of scratches & the odd rust type spot/blemish - asside from spending a day polishing on a buffing wheel that I do not have - any tips for cleaning them?
P.S. I know it has been said here before but Peter's craftsmanship is amazing I am in awe of such ability.
Laverdaroo:
only what you've suggested Ted, attack them first with Autosol and some 'uber; fine wire wool or brass suede brush, might have a good starting point with which to decide.
kent400:
The covers are stainless steel Ted and not chrome. The covers fitted to the CB750 Fours are steel chrome.
If you had sent them with your gauges I would have polished them. Takes five minutes on the bench mop.

I am in the middle here - what I can say as a novice is that there were rust stains on the inside where the semi-captive fixing bolt sits - that came off with some chrome polish. The sides look like thin stainless steel but the outside of the backs have a few small pit marks - not the usual rust spot you get with chrome plating. The lower housings are fully magnetic - is there such a thing as thin chromed steel as opposed to chrome plating?

Not all stainless is rust free it depends on the gade of stainless used and conditions. Even 316 will rust if given the right conditions. Also lower grades are "magnetic".
