I have often wondered about laying one of my stereo speakers on its back , placing a large dish over the woofer,putting the cleaning solution and parts in a plastic jar and listening to Jethro Tull.

Ultrasonic is the way to go. I use 5 small glass jars. Number them put cleaning solution in the first 2, and rinsing solution in the other 3. You can usually get small cleaning baskets from a supplier

Found another way, vintage butter churn.

Switched to a square bottle. Notice there is hardly any vortex now. Looks promising. :woohoo-jumping-smiley-emoticon:

I may modify the magnetic stirrer in future. At present, the hotplate doesn't work unless the spinning motor is on. If I plan to use the hotplate as a parts dryer, I will have to bypass the switch.

I may also modify the motor to add an automatic reverse direction function.

Something weird happened to phone. I don't know if it's the new version of android or Samsung app. Keyboard layout has extra stuff now.

If you click on the 3 dots you get the option of downloading the video. Then you can see it on your video player.

I thought that you were going to spin the liquid and then enter the basket such that it was fixed, and at a greater distance from the magnet. Could be worth trying if magnetism proves to be an issue.

That's too simple. Where's the fun in that. :D

But seriously, I did consider that design. But I didn't think the flow of liquid through such a fine mesh would be enough to clean the watch parts.

Another design I was considering was to move the magnets further out to the periphery, so that the basket is not directly over it.

But I'll test out all methods to see which works best. I've got a pile of scrap watches from ebay. I should probably clean them and sort out the usable parts.

Has anyone tried to build a watch cleaning machine from scratch? Looking at the ones that show up on the bay I am surprised at the prices they fetch here in the UK for what is essentially a fairly simple bit of kit that often needs a lot of work to get them up and running safely.

Although my horological skills are so far not much to write home about I think I should be able to build something that would work but would like to avoid having to re-invent the wheel.

I would be really grateful if you could share your creations.

Many thanks.

I'm thinking about making something using a small drill press. The reversing operation is not figured, as well as the rpm. The basket, may disappear from my wife's,  new tea brewing in a cup, Christmas gift. I have been using the ultrasonic cleaner, and drying in a toaster oven, not the best results, just ok.

The reversing is a real thing. It doscombobulates the parts. With real pro solutions ultasonic is a sideline subject in a machine that spins in both directions. Manufacturers want ultrasonic so if pro you're humped there. But the old Elma manual machines worked great, didn't even reverse. But it was Rubisol or whatever then 3 benzine rinses, so, yeah. Spotless. The 3 benzine rinses help a ton.

 

If you want to make a machine go for it. But count your time, you might see that an old Elma isn't that expensive.

 

I have a machine that distilles alcohol for the rinse, it's from the late 60s. I'm very much looking into reproducing this machine on a basic level, but it's off the map from regular machines. Either go glass jar naphtha brush (and sawdust), or buy commercial solutions and a basic machine, or full 13k Greiner modern machine, which gives similar results, or, make a machine that will do the bare minimum + the time spent making it.

Good thoughts.  I have more money than I will ever be able to spend before I die, but even when it makes no economic sense, I make things that I can buy.  I am an engineer...can't help it.

With regards to making the basket I had a similar idea as HectorLooi posted above with his photos (link to video is faulty) in the sense to use something that is commercially available.

For a basket I found this on Cousins and it had a snug fit into a glass jar. Probably too snug as I note the real machines have a stainless steel mesh around the container walls to act as a wave/current breaker. Off-cuts of stainless steel mesh can be sourced fairly cheaply. Pots like this can be sealed off really well.419111418_IMG_20210214_0944331.thumb.jpg.f2ef6eeaaa6b4a78d8b9cae567e8530c.jpg1802805749_IMG_20210214_0944531.thumb.jpg.7b5ff2c5bafb0f0f7e6536cb21e00086.jpg

I suspect the basket would need a lid to avoid the parts becoming unintentionally airborne but if that lid is made of plywood for example it could serve as a float in an ultrasonic bath?

I have not got a drill press but a cordless drill which has a reverse could work or a small electric motor powered by a 9v battery? The amount of torque required is minimal.

I too am looking to try and build my own machine.  But I don't know where to start. This gentleman had the right idea.

      My first Gruens. Precision 510 and N510R movements.

      By rjenkinsgb · Posted

      Snap! I recently finished my Gruen 510 movement - though the case for mine is in a rather sad state; I'm going to try re-plating it (in nickel, it's not a gold one).   Re. the screws, I got a few of the one gram mixed batches from ebay. I've only needed a couple of screws for things so far, both rare, minuscule types - but both in the mix, after enough time sorting through them! The ones such as normal bridge screws are quite common in those lots.

      Any tips to correct a sloppy error?

      By rjenkinsgb · Posted

      Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      By GuyMontag · Posted

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      By Neverenoughwatches · Posted

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.
