anodize your OEM Ti shifter using coke and 9v batteries
 

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.

if you like, have a try, and get some pics up :D

Haha. High school chemistry put to use. An electrochemical cell...

light blue/greenish with red removed.

i have now found if you put the foil all the way round you get a much more even coating aswell

haha cool ish

Cool. I bet you have fun dying easter eggs :P Maybe you should figure out how to make each color and make a chart and make this a COMPLETE DIY. Cool stuff!

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

there are charts available but to be honest everyone seems to get different results depending on how they do it and how flat the batteries are etc......for anyone having a go once your set up its easy to experiment for yourself

While the science behind it is cool, am I the only one that thinks that rainbow colored shift knobs are kinda silly looking?

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

yeah i'm not leaving it stripy like that, just thought it would show the colours i've managed to get off a little better

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

VERY cool.

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

is the type R shifter Titanium? I have one I got off ebay not sure if its titanium or not...

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

well now you have an easy way to test if it is genuine or not, oem is titanium

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

Very interesting. I support Tyrant's idea for an complete DIY.

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

The non-USDM/CDM ones are. USDM/CDM are aluminum (or as the Brits like to say aluminium).

I saw this done a while back with radiator hose clamps. :thumbup: good info

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

sorry, didnt realise US didnt get titanium shift knobs.

Wasnt trying to rub your noses in it or anything like that ...........honest

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

Lye (Drano or Easy Off oven cleaner) takes the anodizing off aluminum. Dunno if it works with Ti.

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

yeah i think it works on Ti too

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

DRINK THE COKE AFTERWARDS....IT FCUKS YOU UP....

:beer::beer:

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

People use Coke to unclog drains instead of using Drano.

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

People also use Coke as a spermicidal douche. Have been since some window licker decided it worked for her the 1950s. Doesn't mean it actually works, nor does it have any bearing on the product as per what it is intended (consumption).

...on that note, did you know that tap water can dissolve solid steel?!?

Re: anodize your OEM Ti shifter using coke and 9v batteries
 

Cool idea OP. :thumbup:
