Thanks for that Bob

Here it is all cleaned up and on a test run Have to say when the timer alarm went off it made me jump lol

Wow!   What a bargain Andy, that looks like a quite expensive model too.

My thanks to Rafal for the copy of the manual, which I am in the middle of translating using Google Translate. It should do complete pdf's but mine doesn't for some reason so I am doing it line by line.

If you read this Rafal, could you please tell me, if possible, the wiring positions of the three red wires on the back of the timer? When I took it off, it had two wires on one position and one on one of the others. The spring in mine was broken so I repaired that and, using an Ohmmeter, find it connects a+b when off and a+c when on. I took a picture on remove, but it got deleted in error so I am now not sure where the three red wires belong.

 

I also connected a 240V supply to the basket motor and fried it as it is a 12Volt motor but had a 240V wire going into the casing. Turns out there is a Siemens bridge rectifier in front of the clock timer.  Stupid of me not to check first so now need an armature rewind.

 

I am slowly getting the hang of finding my way round the site but I think I may have posted my messages in the wrong place.

 

Thanks,

 

Tom

Hi  Tom,

 

Im not sure if you can make use of this picture as from my experience those machines had different setups ?

It seems that this timer is not really seting time for spinning but opens circut to stop synchro motor from progressing program which is set with those bronze wheels when end switches opens and close on tooths. At least in mine. Only 2 screws have wires connected to them as far I can tell.

Thanks for that Rafal.

 

This is how I have connected mine as well. The sheet you sent me , when translated, says to set the timer to one minute and it will raise the basket motor to the start position the when you press the start button, it will start the machine on its cycle. I can't get mine to do that though. Are you able to see where each of the red wires terminate?

 

I seem to have lost the feed to the basket motor, which did work, and I suspect it is soemthing to do with these red wires. I know one is the main supply from the connector block as the mains wire enters the machine but the other two, I can't see so I may have to completely strip it down. If I do, I will try and make a wiring diagram and send you a copy but, as you say, they are all slightly different. Mine has three wheels driven by the servo motor and only one at the other side, with the four segments, which I assume is for the four stages. I can drive it by lifting the contact on that wheel.

 

Thanks for the quick response to my question. Do you have any other literature on them? I am  keen to try it out.

 

 

Cheers,

 

Tom

Ok, I'm at that point where I'm thinking of splashing out on an Elma Solvex SE.  I've tried for months now to win an auction for a several beat up 1950s machines and my wife can't stand it anymore and offered to buy me a new one!  Am I crazy?  It's a lot of money for just a hobby.  I don't want to be that "All the gear, no idea" guy.  Talk me into it or talk me out of it.  I'm fed up with hand cleaning parts.  Help.

Hi,

Do you repair 52 watches per year? Even if you do, it means 1 watch per week or 1-3 hours per week spent on cleaning. Not a lot, right? Think of cleaning the parts as Strip and Survey - study your watch, check under microscope every component. If you ask me, I do not need "washer and drier", as everything can be easily cleaned with peg-wood sticks, Lighter Fuel or / and ZENITH FORMULA 67 WATERLESS CLEANING SOLUTION NON- AMMONIATED either manually using various brushes, or in UT bath 3-5 minutes at 35-40C.

Hi un less you have the through put to justify the cost and are able to get a return on your investment  I guess the answer is no  I myself use a small jewelry cleaner(ultrasonic) and mini jars, (single portion jam) as used in hotels.  The jars contain the cleaning fluid of your choice and are placed in the U/s which contains warm water up to the level of the cleaning fluid and then started for several mins,  a cost effective way of cleaning and it works whether you use IPA or Ronsonol, Naptha or whaterver. I reckon the cost was  £19 for the cleaner  £10 for the IPA/ ronsonol.   Si for me save your bucks for somthing you really need and can justify.  And take the wife out for a drink.

And don't forget that setting up your Watch Cleaning Machine ? requires some permanent space, accessories, and it takes time to prepare it, then clean it after cleaning watch parts, etc. Not sure if you are actually saving time. 

And also, what i do not like about WCMs & UT bath is that in some cases this way of cleaning removes a bit more than you would like to be removed... Like this black "ink" will be all gone.

I get that hand cleaning in going to be better for the movement and I give you time to inspect each part.  But this is a hobby for me, and as such it needs to remain fun.  I do not find manually cleaning parts fun.  Maybe I've just not got my cleaning system correct yet.  I tend to have to rodico the dirt off each part after cleaning which can take me upwards of 3 hours for even a basic movement.  I have an ultrasonic cleaner but it just doesn't seem to make any difference.  Maybe I should spend some time (and money) trying different things.  I've read (extensively) what everyone else does and know that what's right for one person isn't right for another.  Yet when I watch videos of professionals, they always use a nice watch cleaning machine...

I'm not an impatient man, more efficient.  I'm also not looking for a quick fix or a solution, just a better way of working.

It is important to read, learn, listen to what others recommend, but the final decision is yours, right? If it makes you happy - go for it.

Are there any of you who use a Elma Junior cleaning machine?

I need some technical information and possibly. pictures or video of a working machine!

 

I have the same one. Motor and driving mechnism is working. But connection from motor pulley to cleaning head is missing. That could help me if you can open the arm cover and inside pulley connection.

Hello

Recently I bought a knock off, old style Elma watch cleaning machine. Love it. The spring that controls the motor going up and down the support shaft is quite firm and the tension knob can be a killer on the hands. So I found a scrap piece of wooden corner trim and cut it down to 16 cm to make a brace or stop. Works great!

Ok, so, to start off... I am well out of my element here.. I'm more of a blacksmith than a watch and watch repair guy... That being said, I happen to come into ownership of an Elma watch parts cleaner after helping a friend clear out his great aunt's property after the estate sell. I have had one hell of a time trying to find out what exactly it is, much less any information on it. And what I have found has been minimal to say the least. I've seen several Super Elites sold on eBay, yet I have not seen one exactly like mine. I'm fishing for a some sort of insight as to what I have, and what I should do with it. I am not much of a forum kind of guy, and I am definitely not tech savvy, so I apologize for my unpreparedness with this.

Any idea as to what I should do with it? As I am not in the jewelry or watch repair vein of the hobby/industry.... I don't have any real use for it, and it's something I think should be in the hands of someone who will appreciate it more than I can.

Sorry for my being so inconsiderate to the forums etiquette. I have yet to introduce myself or anything. The name is Holden, and yeah, well outside of my element. I'm more comfortable in a blacksmiths shop not in the virtual world. That being said, thanks again for your response Frank, and anyone else who might be able to point me in the right direction.

Holden-

Hello, I recently bought an Elma Super Elite and I try to figured out with the heating element !

i’m looking for the details of how to assemble the different layers of the heater . I want to know where the white plate goes. I guess it is the following order but i would like to be sure :
From top to bottom : Protective plate => Heater plate => White plate => Base

i’m right ?

Regards,
Nicolas

Hi there, that looks to me like an Elma Basket Holder suitable for use with Elma Super-Elite, Elma RM90, Elma Solvex SE and Elma Solvex RM cleaning machines. To fit Ø8mm spindle with fixing grubs crew. Hope that helps.

I helping my mentor to repair the timer of his old Elma cleaning machine.

The timer is like a kitchen timer, you turn it to the time desired and it winds down to zero then rings a bell. But now, it appears that the friction wheel has worn off and it returns to zero the moment immediately when your hand leaves the knob.

I've stripped the timer down and can see that the friction wheel is part of the mainspring arbor. There appears to be a red phenolic paper washer that is disintegrating and the spring washer can no longer exert adequate pressure to stop the wheel from slipping.

Has anyone attempted to fix something like this before? I told my mentor to replace it with a timer switch or cannibalize a kitchen timer. But he's a stickler for authenticity. 

Thanks in advance.

    • I've been working on an 8-day clock. The dial is decently large, but the actual movement is similar to an oversized pocket watch. The only markings I've been able to find are "Sandoz" on the dial, and on the barrel bridge: An "M" with emphasized serifs "15 Fifteen Jewels", "3 Three Adjustments", and "Made in Switzerland" The serial number 403250 While working on it, the click spring went *ping* into oblivion, and despite my best efforts and strongest magnets, I haven't been able to find it again. At this point, I'm looking to replace it. However, just going off the above markings, I haven't been able to find any information about the movement classification or caliber in order to find a proper replacement. Since it's a click spring, I'm not too concerned about getting an exact replacement just so long as it applies pressure to the click. The original was just a simple spring consisting of a single U-bend and fit into a channel 8.4mm long, 2.9mm wide, and 0.54mm deep. How would I go about finding more information on this movement in order to get a proper spring? Or just search for springs that have the right shape and dimensions?
    • Yes it can;  perhaps impulse jewel can't enter the fork horn, if the shock has  knocked a pallet jewel out of alighnment or bent a pivot. Remove the two black screws then the automatic device, loosen the cock screw by couple turns, raise the bridge just enough to pass the impulse jewel over the fork so to get impulse jewel inside the horn, tighten cock screw. It will run, however , might get stuck again if pallet jewels have got misaligned or a pivot has got bent.
    • A little uninspiring.  It does run though...kinda.
    • I decided to find a knew winding pinion for my Vulcain.  I see some wear on the one I have.  I have the spec sheet on the Vulcain 120 and identified the part as #1246.  I searched around and found scotchwatch.com had one.  $45.  I really want it, so I bought it.  Meanwhile, I continued my search and found a part with a different part number (410) on Northern Watch & Clock Supplies in the UK.  It was just a couple of pounds, so I bought it. Later I looked at the invoice from scotchwatch.com and see that the part I bought is 1246 (410), so I think the part has two numbers.  Well, we will see when they arrive.  On part cost 20x the other one.  I am not complaining...as I am glad that someone takes the effort to maintain an inventory for budding watchmakers like myself.  I just think it is interesting. Learning new things every day.
    • Thank you for your introduction and welcome to this friendly forum. A nice looking watch you are wearing.
