Chroming Regulations

[My Old Landy]

and carbon tet in fire extinguishers

Can we have halon back then please?

 

[Parm]

ahh sod it bring back everything. Including full fat petrol with lead and functional paint stripper with DCM

 

[8ob]

When all this comes into effect is there anything to stop hobby chromers doing their own stuff

I have 2 of them in the back of the shed, no idea what im going to do with them

it isnt that simple to do

I phoned the local fire brigade and they came and took mine away as it is a private address.

I know a lot goes into the polishing ,isn't the actual chroming the easy bit?

no with the tanks transformers and chemicals and putting the electrodes in the right position for chroming its an art and expensive

I am working in a fire station soon, problem is not my local one.

I may ask for advice (and if I can pretend to drive the fire engine with the lights and siren on )

In hard chrome plating its the hexavalent chromium thats transferred in the electrolytic process, this is what gives you the shiny finish

I don't think we refer to the same when saying hard chromium plating. The one I mention gives a rather dull finish before grinding and has a crackled surface to better carry oil film for lubrication of moving parts.

And guineas

dont forget half crowns and florins

Make sure have this caper on video. I want see how the other blue light service may react

Yep. The effort is in the surface prep, chrominance is the easy bit

 

[mtt.tr]

Im yet to meet a chromer who doesn't seem to have brain rot.

Yeah I get that, there is another finish that used as a build up coating so a job can be machined back to original spec.

widely used in aerospace, although these days there seems to be a preference for flame spraying

I didn't know they used Hydrofluoric Acid in chrome plating. That is seriously nasty stuff, only time I've come across it was in wafer fab sites.

Never knew it was involved in chrome plating either, wafer place I worked at, the guys in that part of the HF process looked like space men and that was over 30 years ago

Used to get chrome plating done by a guy in Rushden, not much more than a glorified shed, I should check on dear Doug, hope he's not floating very shiny in one of his tanks!

 

[Farside]

I have a few crank journals to get done,

Quite right; they won't write themselves, you know.

Why not??? A decision to ban wouldn't have been taken lightly. I'm old enough to remember the Montreal protocol banning various chloro-fluoro solvents back in the 1980's. We used huge amounts of Freon113 and people were wondering around saying that losing it would be would be the end of the industrial world. It wasn't, new products and methods were developed which were as good or better and the decision to ban was absolutely right.

Many of EU's bans have been due to lobbying from German businesses that will benefit - not good enviromental or safety reasons. I've seen enough of them recently. An example, EU bought in linked braking systems for motorcycles, a terrible, unsafe idea, at the request of Bosch.
Montreal happens to be in Canada, and that agrement /revisions do not go far enough in my opinion.

I dont know the full details of the process but Cr(vi) is a waste product, not an ingredient. The waste can be treated, it just needs tighter regulation and controls to ensure it is.
I couldnt care less for decorative chrome, but hard chrome is needed for hydraulics and many other items. The result of this is the manufacture will move to India, if it has nit already, where no care is given for controls, it will be an enviromental disaster. Final product wont have Cr(vi) so the Western world wont care.

I knew a guy who worked in chrome plating for 5 years, about 5 years before I knew him. His boss and two others died of throat cancer and he got it too. His words, they "never bothered with PPE" and I suspect the place was lacking proper safety controls. Doubt he is still around, but would be around 55 now if he was, it was about 15 years ago

Vacuum depositon (or physical vapour deposition) is another alternative.
