Anodising
 

I think thats how you spell it does anyone know of a firm that will anadise aluminium parts and remove old anadising?

Sorry its one of them words i cant spell like scruternering.

Anodising:)

Scrutineering :confused:

you can remove anodising with caustic soda(drain cleaner)..comes in crystal form you add water to it and drop your parts in,doesnt take long.

as for anodising you again can do that yourself,but if you dont feel upto it then get the yellow pages out,lots of companies in there.

i used one a few yrs ago to get some alloy hard anodised,i think it was mansfield anodising the name of the company.

Pepsi or coke will turn stuff blue:thumbsup:

Do you just leave it in there?

And FANTA turns it ORANGE:D

haha. Cherryade

fosters :drool:

pi$$ coloured

haha. Yeh ashley use fosters. Your car will be dialled

i would buy the fosters to do the pi$$ coloured anodising then just drink the fosters and love the blue i already have :p

No i want blue :p The reason im asking is ive foudn a shop with one in stock but only in red so i wanted toget it re done in blue.

Mossy could do his ali bits to match his wheels :thumbsup:

I used mansfield anodisers to do the red S4, might be a bit expensive for just one piece mind??
You could always try trish too?

Ash, do you know the sad thing, the servo mount started out as blue, we got it anodised red!!!! It complimented the Matt Francis stuff from Trinity at the time, but it is now the only one we have left.......

haha :woot::lol::cry::cry:

Ill see when i get paid only got a small wage packet this months so its gotta last.

Ash, be very, very, very careful if using caustic soda to remove anodising!

Don't know what's in that stuff but it's mighty powerful. Use a strong plastic or metal container and do it outside, I don't want to know what's in the fumes it produces (and the solution gets hot)!

Also don't leave the parts in for too long, would recommend dipping them using pliers and keeping an eye on the progress.
DO NOT immerse them in the solution and leave them their!
Was recommended to do this to remove the green from Axial AX-10 parts and have now had to order a complete set of linkages etc!
If left alone for a while caustic soda will remove the anodising and then starts on the aluminium itself!
Linkages became shorter, holes bigger and M3 became M3.5! Great!

It works very well but just be cautious and careful!

dont use a metal container,a plastic tupperware box is best,a tiewrap works ok around the object to do,the solution can get quite warm,generally the more cc of solution the cooler it will be,ie if you used a bucket full to do a shock tower it wouldnt get warm..use a small dish and it would get hot.

I can see this ending in tears.

Caustic is in caustic soda, its nasty stuff, it will burn skin and stuff, depending on concentration.

We used to have to wear big green suits when i worked on a caustic plant.:thumbsup:

its only ashley :)

its not too bad in the small concentration you use,just use it outside and when finished pour down the drain..and rinse everything off well.

the industrial stuff is far more concentrated than the commercial drain cleaner you get from wilkos..ive had it on my hands and didnt burn but would still reccomend using protective gloves and eyewear

I thought of doing some home anodising a while back but ended up not doing it because it really is quite dangerous and I like skin and stuff.

This web page is pretty detailed on how to do it but I really wouldn't recommend it! click here

The scariest thing was that there are mail-order places that will send you the nastiest liquids and chemicals by post!!!!:wtf:

its not too bad doing home anodising,ive done it before but you do need to be in an open space because the fumes from the acid is quite toxic.

basically you drop your material in some caustic solution to clean the surface up and remove the oxide layer,then rinse with clean water.

you have a tub containing battery acid and water(i cant remember the exact mixture %) with a piece of lead strip connected to a 12v battery(i used a mains 12v 2 amp adaptor) and the other battery wire connected to your alloy piece,when you drop the cleaned alloy into the acid it will start to strip the top layer away and open the pores of the alloy up,the alloy will turn a milky/champagne colour after about 45 mins to an hour,you then either rinse it off with water and drop into a tub of the dye of your choice(dylon clothe dye is ok) until the colour you want has taken..usually around 30 mins to an hour if i recall.

then you have to rinse the part and drop into a pan of hot water and simmer for an hour or so to seal the surface of the alloy.

Ash, how about you come chat to me at taly and ill get them done for you. any colour i have a building at work who do it. PM me if you want to know more.
