Hello!

So after tinkering with watches I thought I gave it a try with a clock. How hard can it be ;)? First of all you don't need magnifiers :) Actually you need to take a step back to see the entire thing.

Basic questions, if I may: what do you use to oil these beasts? How do you take out and put back the mainspring?

Some photos:

Thank you,

You can remove the mainsprings by hand BUT be very careful them springs can do a lot of damage to you & the clock if they get away. RE-fitting is very difficult by hand. I highly recommend a proper clock spring winder. I use the same machine as in the demo vid below. Notice even with the correct machine they guy uses thick gloves. I use moebuis 8030 which is for small to average size clocks. Looking at your pics the pivots look Ok but check the pivot holes for wear. If significant wear they will need re-bushing.

I always used windles clock oil. Its one of the better oils and can be used with most movements including Long case clocks. You need a clock mainspring winder, I used a boxwood mallet, hit the back of the winding arbor and the cap will come off, then use the mainspring winder to take out the spring. You can get the cap off by putting a screwdriver in the slot of these barrels, not all clock barrels have slots, you can take the spring out by hand but you will distort it, the same for putting it back, but it is not recommended because when you come to wind the spring up you will get an irregular unwind and it can effect the time keeping. 

What you have is an 8 day ting tan movement sometimes called bim bam, I can tell by the three hammers, and it has an anchor escapement .

I am a hobbyist mainly interested in watches, not clocks. This one is just for fun. I wish a I had the means for re-bushing, though I believe this is not the case. I wish I had a winder, but I don't, so I think I will clean the barrel arbors only (naphta and Rodico). The mainsprings don't look too dirty.

I have another problem though - during the disassembly, one of the click-springs broke. Do I need to replace it or can I put a resort spring instead (between the hole in the main plate and an eventually future hole in the click)?

Or is that a BLASPHEMY?

I see by your photo you could have taken out the barrels without taking the whole movement apart. That type of click spring should be available from good clock part suppliers. If you decide to make and adapt a part just make sure it is strong enough to work and hold the click without too much give because if it slipped while winding it will damage the hand of the person that is winding it, broken fingers come to mind. Put a little grease around the click and don't forget to oil the springs and arbors, a little oil in the privet holes, anywhere that to metals meet and touch, a little on the face of the pallets is a must.

oil, oil, oil... I am used to and know the oil for a wrist watch. I don't know them for clocks - clockboy said something about 8030 - I suppose it is ok for the train eheel pivots. Is it also ok to use on the mainspring and pallets? It seems unlikely.

 

Anyway, I just bit the bullet and cleaned the mainsprings. I just took them out and put them back by hand - that was a workout, I'm still shaking a bit :) I cleaned them with a piece of cotton with naphta on it. They look much better now. I just need to oil them now - I suppose it is like for the watch mainsprings - just put four drops of oil  on the MS and two on the top and bottom of the barrel - but again, what type of oil?

Also, I am still thinking about the click spring solution.

wall clock oil [for those that don't have jewels] :  since the pivots are "metal  on metal"    i see no problem by using multi viscosity motor oil there.   vinn

    • I'm sure it's the ancien. My measurements: A = 342. The slight bend in the pivot would make much less than a thousandth of a mm difference to this so I don't think 348 is plausible unless there has been significant wear on the pivots. B is hard to measure without first removing the balance wheel. I measured to the other side of the balance wheel as best I could (263) then subtracted the thickness of the wheel (69) to get 194. This could easily be three or four hundredths out, so 195 looks right. (196 could also be right.) J couldn't be measured. I did my best to measure where the balance wheel has been riveted on and got about 95, so 85 before riveting is plausible. (60 is not.) G again couldn't be measured without first removing the roller. I get 37 where the staff emerges from the roller so 41 at the other end of the taper seems plausible. (43 is also plausible to me.) K = 60. (Definitely larger than 55.)   I've never replaced a balance staff; it'll be a new adventure for me. I'll have to read up on how to maximise my chance of removing the old one without damaging the balance wheel without having access to a lathe. I also need to explore how to remove the roller without damaging it. I won't actually place an order until I've gone through the rest of the movement. With the number of issues I've already found, I'll be amazed if I don't have more surprises in store. There are some watch part suppliers in Australia but nothing like Cousins or Otto Frei or Jules Borel. AllTimeCo is fine for basic parts for modern watches: batteries, bands, some crowns, stems, seals, movements, some tools, etc., but not really anything for vintage watches. Australian Jewellers Supplies is similar. Cousins charges about £9 for shipping to Australia which is about AU$19 and not too bad (considering Australian parcel post is $11) but I still want to minimise the number of times I'm paying it. I need to explore other options closer to home. There may be something in Singapore or China that would have what I want and ship it faster/more economically.  
    • Hi, I just finished the service of a Rolex 3135. Amplitude is great, 295 degrees horizontal after 2 hours and 280 after 12 hours. Vertical positions are 25 degrees down on those. I am however seeing a rate variation with temperature. I have 0 SPD on wrist, say 38 degrees and +7 SPD at 18 degrees room temperature. That equates to +0.35 SPD which is within spec I believe (+-0.5 SPD/ Deg C max). It just seems more than I would expect from such a high quality movement. To put that in context, I see similar rate variation with temperature for a Seiko 7S26. Just wondering what you guys see. Thanks, Steve.
    • For years I've done it the el-cheapo way (read: cleaning by hand). Bought a 2nd Elma S15(H) ultra-sonic, including proper cleaning-fluids (Elma WF Pro (cleaning) & Elma Suprol Pro (rinse)) and entered a complete different cleaning world. These cleaning fluids are none-water based and not that easy to obtain. Initially I bought these fluids in Germany "SKSONIC" (www.sksonic.de) but last year they stopped shipping international. Perhaps they resumed international shipping? You can always ask them. You could also ask @VWatchie, he lives "next-door". As for the fumes; I use the ultra-sonic in my garage, partly for the fumes, but more for our dog ...... he goes "bananas" when I switch on the ultra-sonic. Oh, next on your list (if you consider watch-repair as a long-time hobby), a Microscope (up to 50x is enough).  Pegwood leaves, observed under the microscope that is, whole tree-trunks behind 🫣 Ultra-sonic, in combination with proper cleaning fluids, takes care of the cleaning.
    • How do I remove the hairspring from an ETA? 2846. Balance  staff pivot is broken and I need to transfer the spring over to a new wheel. But the spring stud is not removable. It seems it almost looks like a snap ring at the top of the balance cock or am I missing something?
