Please tell us the process
By Steve McClelland on Sunday, May 10, 2015 - 10:38 pm:Dean in the appliance business, years ago at Hardwick Stove Co. We had a pickle room, it was about 100--120 degreees in there year round, not a place most wanted too work. It was huge process with a whole series of boiling hot process tanks, everything we put used to porcelain enamel coatings on was pickled, funny thing was with newly stamped steel parts they came out of that room with a ugly dark green tent. I always wondered if that's where the term pickled came from. I doubt you could ever get a part any cleaner or grease free than by pickling it...

Thx
By Kohnke Rebabbitting, Clare, Iowa on Monday, May 11, 2015 - 04:24 pm:Dean, a guy e-mailed me and said, what you done with the Lie was a form of cleaning operation.
Pickling is done with acid, and that rusts even if coated with oil.
The caustic on the tinning surface, I am thinking will rust also, open to the air, or covered with tinning.
So I am thinking, if you didn't sand blast to bare metal after, it may not be the best bond later. Nothing sticks to dirt.

By Frank van Ekeren (Australia) on Monday, May 11, 2015 - 05:20 pm:Pickling was old skool stuff in the radiator shop, hot caustic clean first then the sulphuric acid one, that stuff was and is very toxic, never breath in the fumes, tinning was done straight away after a good fresh water clean, you had a few hours to do that before it sort of oxidised.
These days sand blasting is much easier and healthier.
By Dean Yoder, Iowa City IA. on Monday, May 11, 2015 - 09:09 pm:Herm,
Pickling with boiling lye does not cause rust it removes rust and oil. If the tinning is properly bonded oxygen can not get to the base metal to cause rust .
I have sand blasted & used many different fluxes.
The K rods used anchor holes to hold the babbitt.
I prefer Tinned rods and that is how I did them.
I felt i needed to get the oil out of the base metal that is why I pickled them in a boiling lie water bath.
By Dean Yoder, Iowa City IA. on Monday, May 11, 2015 - 09:22 pm:Herm,
I agree Nothing sticks to dirt.
I say Nothing sticks to oil & boiling lie water cleans deeper than sand.
