Here is where I decided to stop de-scaling my heating element, unfortunately I did not take a before picture for the heating element, but one can make an educated guess from the condition of the boiler :P
There is still a very small amount of scale at the end, but decided it was not worth it.
This is the "shiny" change in appearance I was talking about earlier, I am guessing it was some kind of plating from other parts of heating element, or the brass fitting on the end cap I was descaling in the same bucket. I had thought that the copper plated the brass, not the other way around, but it kind of looks like brass. Either way i am not terrible concerned about it...its clean and does not appear to be damaged.
For this I first used some metal etching acid (left over from when my dad chemically cleaned our garage floor). I used this to take off most of the green tint treatment that was originally on it, that had begun to show its age (As there was rust despite its presence). this also took care of some of the rust.
once I was finished with this i sanded everything, some with a power sander, and the hard to reach areas by hand.
(sorry no pictures of this, not that it was much to look at)
once I was down to bare metal and any lose rust had been cleaned off, i used "rust reformer" from autozone, i simply painted this on the areas that seemed to need it.
While the rust reformer dried, I decided to test the paint i had picked out on a piece that was clean of any rust.
I decided to use the same paint I used to paint my engine. So that it could withstand the heat of the boiler, and last for years to come. It is "engine enamel" made by RustOleum , also bought at Autozone.
Here is what it looks like (matte black):
NOTE: If you have the money to powder-coat it. DO IT! This was a pain, and was the limiting factor for most of the Restoration. It is also the part that I am most worried about. (rust bubbling through that wasn't completely "reformed" or sealed in by the paint.
Once I realized there was no pump. I emailed the guy I had bought it from asking if he had it laying around some where. (As we had agreed on the price under the assumption i was receiving a working when pulled espresso machine).
He looked around and didn't find it. He went the extra mile and called the guy that had switched out this older machine for a new one. The guy had simply taken the pump with him, and agreed to bring it back.
I have not seen the pump yet, but am confident that it will be in working order, however I am not sure what definition of "pump" were going by, the motor + pump, or just pump. My dad was already making a trip to Chicago and is picking it up for me tomorrow and will be back this weekend, so we will find out...
