Hi Guys,

 

I thought I'd put this up to help those with nasty rusted movements.

 

The product is called Evapo-Rust, and it's a soak for rusted parts that removes rust without ANY scrubbing, and will not affect paint, plating and safe for all metals.

 

http://www.evapo-rust.com/

 

Removes even heavy rust completely
Non-toxic, non-corrosive, safe on skin
No fumes or bad odors, non-flammable, no VOC's
Biodegradable, water soluble
Requires no special equipment
***Will not harm unrusted steel, safe on other metals***
Will not affect plastic, PVC, Viton and most paints

 

I found this product through a vintage Radio/TV Restoration Channel on YouTube.

Here's his review on this product ... he was extremely impressed by it.

I hope this is useful and makes those water damage repairs a little easier.

Hi Lawson, have you tried it in watches yet. I'm curious about the result. I got a watch with very rusted parts I opted to replace the movement completely (just yesterday!) The "customer" was very happy but she didn't know how much trouble I went through (that fiberglass from the rust brushes can give you an itch and then, the involved tweezers work on the fingers!). I wish I had known about this product.

Hi Bob,

 

No I haven't yet, not on watch parts; but metal and brass is metal and brass.  Before you are consider replacing the movement, I'd test first with some of the cheaper parts that you'd intended to throw in the bin anyway.

It's like US$22 for a gallon so it's not going to be an expensive test.

I have seen this used on some very old and rare and delicate radio parts which are impossible to replace, and they came out completely rust free, didn't remove the 60yr/old printing on the metal, and didn't remove the cadmium plating ... I was VERY impressed.

 

ps... I hear you about the fibreglass pens, I've used those before and had glass in my fingers for days!!

I have been doing a little research on this product and it seems to be excellent.

I did find this warning from another forum:-

"I found that on some paints that the Oxalic Acid can change the shade of colour, thought the paint remains unharmed. The paint involved was as below a light khaki spray paint.

That even though it is said that Evaporust with not harm paint, this is not completely true for some paints. I had it soften the paint and make it go all wrinkly. It also removed gun blueing and shellac. The paint involved was a light khaki spray painting on a tin."

My fear is that the shellac removing quality may cause big problems if you're not careful!

I'm still going to buy some as I have lots of projects where paint and shellac are not present.

Yes, they disclose on their Australian site that paints created with oxides may be affected.

"Will not effect plastic, PVC, Viton and non-oxide based paints"

Here's the link:

They also explain how it works on the Australian site too:

I definitely wouldn't soak a dial plate in it without being absolutely sure it's paint is enamel based; and even then it would be a risk.  I posted this information for rust removal for movement parts only.

If the pallet is rusted, wouldn't you remove the stones before attempting to removing rust?  So perhaps the shellac removal is a bit of a bonus to get the forks nice and clean too before re-fitting the stones.

      Stem removal after fitting hands

      By PeterS · Posted

      I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.

      Hope you mum keeps on mending. I was adamant that I was going to get myself going after my stroke. I was only 52. I still have a lot of life left to live. Some people give up. Some people don't let it beat them. Your mum sounds like one of the winners. 👍

      I'm going to be setting up a decent little workshop here at home.

      Moved in. Now working out the best place to have things so moving around the room makes sense. The wooden movement testing rig may end up being suspended from the roof with some pulleys and ropes that I salvaged from some alfresco blinds that we replaced. I always seem to salvage things from things we scrap thinking, "I have an idea what I can use these for." I hope I'm not the only one that does that. My wife hates me for it. "What are you going to do with all this crap?" Anyway, here you go. If anyone has suggestions for workflow around a room, speak up. All Ideas are appreciated. The bench on wheels will carry either a laptop or my Samsung table for using with the little camera that is on the tripod for photos while dismantling etc. The small bar fridge in the corners going to have water etc in it and I might move the coffee maker from the kitchen out there as I am the only one that uses it. I want to get an ultrasonic cleaner so I may set up some sort of cleaning rig in front of the glass of the sliding door. Where the grandmother clock is currently standing. I'm hoping that I will be able to transition my working area, which is the table that the stool is sitting in front of, fairly easily between clocks and watches. I'll be doing my best to make sure that tools for each are separatedwhen stored. Logistics. I'll have a bit of wall space for being able to hang clocks if I find some that I wish to keep or hopefully at some time to be able to hang customer clocks for monitoring after servicing/repairs. The clock on the left in the blue pillow slip and the grandmother clock are earmarked for  Jarryd and his wife, Sara. He helped me move the benches in today. And then went on to tell me that ticking clocks drive him nuts. Who doesn't like the rhythmic ticking of a clock? I have a green pad for adding to the bench for a working surface. It is not a cutting mat or one of the Bergeon mats. It is actually a green desk writing mat. Was really cheap and will do exactly what I want, I think. I also have to get the sparkies back that put our new stove in to put some power points on the walls behind the benches. Hopefully this is all going to go well. I'm excited about it. It'll beat having to live out in the garage doing it. The other thing I have to do is cut a circle or square of plastic to go over the bouncing watch or clock part black hole in the middle of the floor. I would pretty much guarantee that anything that sproings off the bench would end up going straight down that drain. 😄      I think I have been on this forum about 4 years and still yet to really strike a blow. That's a bit sad isn't it. Signed up to Mark's watch course and have yet to buy the movement for working on. Have most of the tools I think I will need so now all just a matter of will.   I have to make a crank handle for my Joe Collins spring winder as well and some spring retaining tubes as I can't find where I can buy them. I will be salvaging (here I go again) the aluminium tubing from my old hang glider which I have to scrap as I can't fly anymore and it is too old to sell. All the aluminium tubing is aircraft grade so I am hoping it will be suitable for the winder. I have also been making a bushing tool and I have just worked out that it will work well with my Dremel stand. So another thing that I can turn into a working tool. Don't know if you guys have ever seen the ad about the guy that buys himself a new 4WD and the son says "We're going to need a bigger boat." So Liz is looking at all the stuff we have to get rid of and says "We're going to need a bigger bin." Really difficult to work out how big a Dempster bin we need. Sigh.

      Stem removal after fitting hands

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.
