I've been using and abusing ultrasonic cleaners for more than 30 years. I've also repaired many units for friends. I've encountered brands like Elma and L&R Quantrex, and unbranded ones like Chine

Like almost everything else in this group we've discussed this before. So I have a link all kinds of ideas and I swiped a picture out of the link to post here. I'm using commercial watch cleaning

Really? Maybe during the war it was the only thing available. Below a page from an early 1900 watchemaking book, benzine is the same product is still best fo degreasing, and post-ammonia rinsing. You

Is that the guy that has a seemingly bottomless pile of crudded-up Seiko's that ship out of the Philippines? At least those are from a tropical environment, which Russia very much does not have.

Thanks for the feedback, all...thanks, Mark....I had little doubt that you would not sign off on cutting a corner like that...I knew it would not be the right way to do it, so that, I won't do...

Again, thanks.

They make me think of lab rats...after they are used up in the lab they are disposed of...only being movements they are sold on ebay!  :)

 

I buy some of those once in a while and feed them and care for them properly...they are sometimes good for spares or to make one full movement out of the bunch...just sometimes! :)

 

Yeah, that last sentence was about the watches not the rats! :D

Where DOES Ramon get them from? !?

Bottom of the sea? [emoji1]

 

Well, think about it - Dive watches? Don't they sometimes fall off? 

 

Typical beach / dive site  recovered with a metal detector stuff. Could have been sitting for years in a salt water environment, thus the verdigris :-)

Had some good ones from Ramon over the years, a little slow posting but well worth the wait. He obviously knows some good Philippine fishermen who have given up catching fish & just go out & trawl for lost divers watches - a very lucrative trade.

When I buy individual watches from Ramon I have about a 50 percent recovery rate, even those like I posted most of the crud is on the alloy of the rotors, get quite a lot of good spare parts from them, last batch I bought 27, of those 7 were 6119c's and I reckon I could build at least 4 good movements from them - all pot luck!

 

ro63rto, I have 3 nice Seiko 5 Sports 100 like that out of 4 I purchased, sometimes you can successfully restore the crystals by a bit of grinding and polishing, they stand proud of the bezel enough to do in situ, though I can see yours has some chips and needs replacing, nice one!

Chinese product on steroids.......... :nurse:

 

I got my "Ultra"-sonic today. Indeed it takes 2xAA, parallel ! So, this means that the little electro-motor, with a small eccentric, runs on only 1.5V.........how boring !

Lets crank it up 3x.......or perhaps 4x? Yes, it takes 6V, draws over 0.5 Amps and for sure: something is happening !!  :D

 

4x more oomph out £2.99.......... 20.000 waves / minute !!?? Now we are talking !!  :thumbsu:

I found a 5.5 V DC adapter and it seems to be quite happy. Obviously there is more strain on the shaft and winding's, but at 1.5V it was a "pensioners" speed.

Now it's in the fast-lane.........how long it will last.......... I think if you don't let it run for hours........ still a long time .

Bursting in flame? It's just 5.5V and it has its own water on top :D

Of course, you can let it run on the 1.5V.............perhaps forever! So is the cleaning time.................

I once learned the Scottish expression: "Gie it Laldy" :D

 

Yes, I also used a variable bench power supply and @ 6V our dog started to look nervous.......

So, mine runs now on 5.5V ;)

Myself I think he pays the kids that scour the rubbish dumps in the Philippines for them, probably a Peso per hundred. :D

Hi all,

I am out shopping for loads of equipment, tools and so and I almost forgot about how I will clean all the parts :)

On eBay there is a vast variety of different cleaners, I came across this one:

http://www.ebay.co.uk/itm/600ML-Digital-Jewelry-Glasses-Watch-Ultrasonic-Cleaner-Cleaning-Machine-35W-/152015232796?hash=item2364d05f1c:g:BSUAAOSwv9hW5nTz

 

 

Anybody using these?

Or any other cleaner for budget of 30£?

These ultrasonic cleaners use only usual tap water?

Thanks for your help.

the manual says that the machine has 3 minute cycles. How long do you usually keep the part for cleaning? Something like 15 minutes meaning 5 cycles with this machine?

Thanks.

I have a very similar one that I got on the bay used for 15$ US. I use tap water in the cleaner, and then put movement parts in a beaker with cleaning solution and then set the beaker in the water. I usually run two cycles, for a total of six minutes or so, seems to do the job. 

Cheers!

Thank you,

what kind of cleaning solution you put into the beaker? And the beaker is glass one?

I guess you can't just put anything into the cleaner because you could damage it in the long term right?

    • I bought this for my new watch bench. It is nice but because of the way you work on a watch bench, the lamp is mounted on the same plane as your work space (this is higher than if it were a typical work bench).  As a result, the lamp cannot pivot upward enough to get optimal positions. So, what I had to do was design and print an short extender that pushes the fulcrum of the lamp away from the manufactured pivot point.  This allows me more range of motion. I am pretty happy with how it turned out.
    • This purchase must qualify:
    • Please keep us posted though. It's a beautiful clock and well worth a bit of time and effort to get it back to it's original glory. Good luck!
    • Did a bit more today on my Hettich. I also mucked around with practising on the top plate from the second Hettich that I bought. The calico wheel can leave marks and I am being gentle. I am certainly not pushing the plate into the wheel. I could easily stall the bench grinder that I am polishing on. I am wondering if Hettich started to use a lower grade of brass? I still cannot polish the brass to a mirror finish. On my Hettich (older) I have had to emery one of the posts that supports the movement and after 600 grit then 1500 grit, straight to Tripoli on my stitched wheel, then green on the calico wheel and the post is spotless. Absolutely gleams. post has a steel nut on the top of it that was rusty and affected by the battery acid. It is now polished as best as can be done and then I mucked around with a bit of heat and have changed the colour of the nut which looks quite good now. It was black originally. I have done several jobs now by hand where a having a lathe would have been so much quicker. Have to get rid of the Esprit first. Then I might have a chance.
