Title: Easily etch some markings on your kettle.
Post by: dk4545 on March 11, 2014, 10:41:31 PM
Not really sure where to post this but I thought it was genius.

Found via hackaday.com http://hackaday.com/2014/03/09/fetching-etchings-for-stainless-steel/

I'm definitely gonna try this on my keggle build. Looking at the comments they seem to think that rust isn't an issue either  ;D

The secret lies in the stencils he used.

Where can we get them?

This is on homebrewtalk and there was one guy who did etch a hop cone on the front if his kettle.

Anyone know someone who has a vinyl stencil cutter?

We could then get stencils made of the "rabbit with the big balls" for our stainless stuff

You can also etch glass with this stuff but be careful, it also etches fingerprints

Ah Yes!

My old favourite Hydroflouric Acid ( HF)! The evil sister to HydroChloric acid, it is about the nastiest damn acid there is.

In my old chemistry department the HF lab was a bit like outer-space when it came to the safety gear (now called PPE) that you had to wear to work with the stuff.

It does etch glass though :)

Would this etching result in rusting or anything?

When I found this originally most comments on that site seemed to think it wasn't a problem. Now more comments have popped up doubting this so don't take my word on it. More research required.

On the plus side my 4 elements turned up so the keggle build begins at last ;D expect plenty of noob questions!

Never one for patience, I thought I'd whip out the old trusty 12V power supply and give this a shot :)
(http://i679.photobucket.com/albums/vv152/magnethead123/Beer/20140315_125316_zps31c085db.jpg)

Tried a test piece here
(http://i679.photobucket.com/albums/vv152/magnethead123/Beer/20140315_130034_zps6c3c6900.jpg)
Which turned out fine
(http://i679.photobucket.com/albums/vv152/magnethead123/Beer/20140315_130224_zps4e90216b.jpg)

So stensiled the pot up
(http://i679.photobucket.com/albums/vv152/magnethead123/Beer/20140316_120507_zps6901e2dc.jpg)
(http://i679.photobucket.com/albums/vv152/magnethead123/Beer/20140316_123155_zps463cf412.jpg)

and here's the final result  :P Only time will tell if the numbers start to Rust....I'll report back after 6 months to let you know

Stensils were 1 euro from that craft shop in Blanchardstown....use the negative once you remove the numbers...see above pics

The numbers will NOT rust!

All you have done is to electro-chemically etch the Shinny/polished surface of the pot.

You have just taken a very fine polished surface and reduced the surface finish to a more "scratched" finish

Its as if you sandblasted or abrabed the surface with abrasive paper to remove its shine!

Unlike the mechanical process above yu can use stencils :)

Aparently in the Bio/Pharma industry a similar process is used to electro-clean vessels.

(Not sure about this so if any one in the pharma/bio industry cares to chip - please do)

QuoteThe numbers will NOT rust!

Good to know as I was going to try it anyway! :D

@magnethead: looks good

I know this is an old thread.... but I think the etching process has just been upgraded ;p

Not sure what's going on here, Looks like a mini welder, but leaves a decent black mark, and if you're handy with a pencil and a bit artistic ...this could be for you....I'll stick to the stencils

It's hard to expel a corpse :-)
He using a reversible European type plug top, which means he won't know which terminal is live or which terminal in neutral.  It's not the hand with the glove I'd worry about its the one holding the knife, if it touches the blade or the rivets in the handle he won't need the light bulb to light up the room.
You really have to wonder sometimes  :'(
