Anodize your oem Titanium gear knob using coke and batteries
Geplaatst: wo 31 maart 2010, 16:01Opgelet, werkt alleen bij titanium. Die zitten standaard in de ITR en waarschijnlijk nog andere R Modellen
I was reading earlier today that Titanium can be anodized using coke and 9v batteries.....only thing i had made of titanium was my oem gear knob....well i had to have a try for myself.
what you need is a non metallic container (mug) put a folded bit of aluminium foil down one side of the mug, connected a wire for the negative (note in my pic i have the red and black leads the wrong way round GEARKNOB GOES TO BATTERY POSITIVE, FOIL GOES TO NEGATIVE). i attached my gearknob to a bolt and hung it into the coke (i used diet but i dont think it matters) THE GEARKNOB AND FOIL MUST NOT TOUCH.
the best way to do it is get your gearknob hanging in the coke and make sure theyre not touching before you connect the battery (batteries).
For my first attempt i used two batteries for 18v and got the results below after about 1 minute, a bit blotchy and not really the colour i was looking for.
so i added another battery and put it back in for another minute..... getting more like it now
i then started trying again, adding more and more batteries, but it just started going a bit grey. i sanded it down with a bit of wet and dry in a drill (took about 30 secs) and tryed a few more times. to get it looking like below i had 7 batteries connected together (63v, i think voltages upto 150v are used) and connected the power for about 3 secs, span it round 180 degrees and gave it another 3 secs.this was because i found the side nearest the foil changes colour a lot more quickly.
The idea is that different colours can be gained by using different voltages, but you would usually have an adjustable power supply and better solutions than coke to get a broad spectrum of repeatable colouring. even so, just with the batteries and coke, i'm sure you can get good results by experimenting a bit........there's a lot more info out there on this, i have barely touched the surface.
