I searched for this topic both here and through Google.  Has anyone had any experience with this and if there are any adverse reactions between aluminum and the standard cleaning solutions, specifically the Zenith brand?  Thanks.

Ammoniated cleaning solutions react with aluminium, producing a lot of tiny bubbles of hydrogen.

If left in the solution for too long, the surface will end up with pitting.

I'm sure you said you were worried about this with your Indian Pearl cleaning basket Hector.

cleaning products with ammonia in watch repair do a beautiful job of making things bright and shiny. But ammonia has interesting properties with all membranes as far as I can tell maybe not steal perhaps. But brass leave it to longer elevate the temperature and the watch cleaning product and you'll frost the plates. the usually everyone recommends room temperature do not elevate the temperature the cleaning product at all. The big question is typically how long four minutes seems to work nice for brass or standard watches no idea for aluminum.

maybe try a piece of aluminum foil see how long it will last before it disintegrates. You could probably get by with a couple of minutes maybe even the same as you would a normal watch.

them attaching a technical communications which unfortunately does not specify anything related the cleaning. But it does cover a few things on putting the screws in probably concerned about the soft metal and them stripping.

Thanks.  I found some cleaning jar wavebreaker material in aluminum which was cheaper than stainless steel.  It would be sitting in the solution for extended periods.  I am going to try a few small jars of cleaning and rinsing solutions with strips of aluminum foil in them in a safe location.

I just found 2 things about this topic:  1) from personal testing with aluminum foil in small jars of both the cleaner and the rinse, I found no reaction; 2) I reached out to Zenith Solutions corporate contact information and they confirmed that their products do not react with aluminum.

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.
