The rust experiment is coming long but it got upset by some cops stopping by to ask about a neighbor I didnt know. Apparently, a couple moved in & then split a couple of months later just ahead of bounty hunters to avoid a heavy-duty warrant. HPD came around to find anything they could and it took about 1/2 hour to get them to understand that, yes, Im on the same floor but, no, I never met them, heard anything about them or knew anything about them. As a result, Naval Jelly & Coke treatments (Naval Jelly: only the drill press base) that should have only lasted 10 minutes wound up over half an hour which didnt do them any good. The rest of the Naval Jelly items were timed significantly better. The molasses dip lasted four days and included a few things I have no clue what are. I also tried some non-steel items just for fun.
It took a while to find something I didnt mind being blackened by the tannin in Extend and tea (It converts red rust to black rust which is actually a protective layer.) For the former, I found pieces of a small Swiss turns I got for parts to complete my other one and a watch parts tin. For the tea, I picked out some wing nuts, the motor & headstock position lock screws & drawbar for the drill press plus a couple thumb screws. The tea dip lasted a week.
Okay, pictures. The first group is of most of the items to be treated followed by pictures after the first pass.
Okay, heres the Naval Jelly and Molasses before the first pass:
And the Naval Jelly after pass 1. Note that I added a bezel chuck to the items treated since it was there and it was a skosh rusted.
The molasses didnt cover the entire jewelers saw frames but it did cover enough. I put the brass Jacot tool frame in for the fun of it, not knowing quite what it would do. The same is true for some other bits there, some of which are complete mysteries.
I dont drink Coca-Cola, but their secret formula reportedly has sufficient phosphoric acid to do something worthwhile. The cross slide has been sitting around disassembled for a while and Id really like to get the screws out if I can. Its not really necessary but it would be cool.
The screws still wont budge. I think it is written somewhere that theyre gonna stay.
Okay, Extend and tea. Nothing here is critical, as I mentioned before. Actually, its all pretty much non-critical. This is a good thing.
Extend is serious about blackness. Everything thats black now started off kind of a dirty milk grey then magically transformed to black as it dried. To prove I dont have a life, I thought the process so cool that I dug up some rusty scrap and applied Extend to that as well just to watch it turn black. Okay, it doesnt take much to entertain me.
Okay, tea which is what started this whole thing. It is a limited urban legend. Some rust was blackened after a week but not so much Id call it a worthwhile way to do things.
Okay, now what. The tea-dipped watchmakers drill press parts will get hit with Naval Jelly while the base will get a touch with oil and wet n dry to finish it up. The two Swiss turns will be re-polished, removing any residue from the treatments they went through. Like the drill press base, the saw frames will get abraded into submission and fitted with new blades one each 2 and a 2/0.
The cross slide, which did degrease and clean up some, will also get the oil & wet n dry treatment and be put in service on the 8mm lathe while I repair the Wolf Jahn and fit it with a milling adapter. Later on, who knows; it may become part of a CNC experiment. Or I may just use it when I dont have to get fancy.
This isnt cast in stone, by the way. Im thinking about giving the good Swiss turns and a few other items the Coke treatment before anything else but with regular Pepsi this time. (I managed to wind up with this rather than diet Pepsi which I prefer.) Im just curious what the results will be.
Among my itty bitty parts, I have some watch screws and other tiny parts that have surface rust on them so somewhere down the line, theyll get de-rusted as well. The results of all this will determine the method or methods I use when that happens. Maybe a month of tea therapy?
All this from a simple question about tea.
Best regards,
Kludge
