Quick question for the brains trust. 
How does one differentiate between the locking wheel, gathering pallet wheel, strike intermediate wheel and the third wheel for example?

 In figure 25, the diagram seems to show them as all very similar?

 Am i missing something or is it just experience that I am missing?

Hi Michael  There are two books from Donald De Carle, Practical clock repairing and watch and clock repairing,  So I take it you have the clock repairing one. 

the locking wheel has a pin on the edge of the wheel to lock  and release  the long lever.

The strike warning wheel is similar with a pin to lock and release the strike

The third wheel has no pin

Because the locking wheels look very similar in construction it is important when dismantling clocks to keep all the strike parts together, same with the going side and the chime side and label each container so as to avoid confusion on re assembly

Correct. I just have Practical Clock Repairing for now. Have started the book several times. Other things just keep getting in the way.

I have focussed again on just doing clocks for now. So I thank the guys that answered my other topic. The pocket watch can wait until I get better at all of this. I'm still chuffed that I have it. I have looked up the prices of sterling silver fob chains for it. It looks like I will spend more on a chain that what the watch cost.

Maybe I'll just use the chromed one that came with my pocket watch from my wife for now.

I know what I need for the clocks that I have and I probably have enough tools at this point to be able to get by. I will get myself some cleaning chemicals and then work out a plan of attack from there. If anyone knows of a good guide to make my own burnisher, that would be appreciated.

A mate up the road has a laser cutter, so I am going to give him the plans for the Joe Collins winder and he willl cut all the pieces for me.

Happy that I have got my head back in the game.

Looks like watchweasol has answered your question. It would help you if you watched a few videos on Youtube to understand which each part plays in the chiming and striking. It would also have been better if the diagram had the parts in order instead of all over the place.

To work on clocks you will need decent screwdrivers, decent pliers and tweezers. I also have some small  BA/Metric spanners  a small adjustable and a few others bits gathered over the years such as brushes etc . Initially for cleaning use some hi grade petroleum for primary cleaning dirty clocks, I use some of the PRIORY polishes clock cleaner concentrate dilutes to 7:1 do a 500ml bottle goes a long way preferably use distilled water. Drying is the key.  Peg wood for the pivot holes and some Windle's clock  oil. With all the above you will manage to clean most clocks.  Bushing plates and re pivoting is a long way in the future but read the books watch the videos, when I started with clocks there was only books and I STILL read them. You may want a volt meter for the odd electric job and battery testing but take small steps don't dive in to three train chiming clocks untill you understand the single train and striking clocks (two trains)   remember small steps, and don't over complicate things it just fogs the mind        all the best

I also find taking pictures helps. Especially of the strike wheel and associated levers and the general position of things prior to disassemble. it's always good to have a picture to go back to.

I’m currently studying the DLC and managed to find the same Bentima movement as used in the lessons, trouble is, with a mentor by my side once a week that timepiece has been stripped, bushed, pivots polished and back together as habe numerous customers clocks mostly French strike Mantel clocks and good Haller movements etc. 

In the DLC I think you finish the Bentima movement in lesson 10 and never go near strike or chimes. So at the moment my studies stopped at lesson 5 as practical work took over whoops.

So stay with simple timepieces until you are happy to move onto strike movements , I’ve learnt a lot from my mentor that books don’t explain very well, so use us here on the forum to aid you as you progress.

Books can only help you so much. There's nothing like getting your hands dirty, books will not cover all obstacles you might have to confront only the popular ones.  Start with a time piece then a strike then chime, then do the same only this time French I don't expect you to have chiming French movements. Then French carriage clocks Timepiece, strike then if possible  French Grand Sonnerie. Longcase clocks start with an 8 Day strike then the 30 hour ones as these are much more likely to have far more wear to them. When you are prolific in that lot you should be able to tackle any clock that comes your way. I have left out those horrid battery and electric movements. I have covered just the basic movements.

There is no substitute for practical experience. Books as OH says only can teach you so much. As you continue to learn the books will be your guide.  I personaly embrace all clocks quartz /electric and have been known to dismantle a quartz module and repair it not because of cost but to keep its originality.

    • Hello and welcome to the fo4um. Enjoy
    • Welcome to the forum, enjoy.
    • You're asking a pretty broad question and you didn't specify the machine but yes it's simple especially if you have the right machine. The question has problems but I'll take it as it is. Is it really that simple yes especially if you have the right machine. So in the video below he's making a screw and yes it really is that simple but pay attention to the machine it is not simple at all probably wasn't cheap but it is small it will probably fit in your garage. Unfortunately wouldn't fit in my garage as it's far too cluttered up with things. In the video he talks about making a screw and pay attention to the machine. The machine has lots and lots and lots of cutters and lots of things to do lots of machining all-in-one machine conceivably one step after another all programmable. If you look at his channel lots of CNC's stuff and there are several other videos related to this machine. He goes to the factory where they talk about it and show all the other machines they make in Switzerland.  I did look up the specifications the machine I don't recall the price it's not going to cut wheels I think it has a maximum diameter around 11 mm basically it's really good for making small diameter watch parts. Then in one of the other videos he goes to a factory that used to make parts with waterpowered machinery been in business for 100 years and everything they now make is made with CNC machines including this one. What was interesting with the factory photo was that when they make some parts they can put them on a optical comparator comparator compares with whatever the reference is and the machine can be programmed to adjust its cutting to make sure everything is actually being made to specifications. Oh and then somewhere in all of this there was at least one picture of a balance staff can't have a CNC Swiss machine without making balance staffs.   It would be really nice if we had pictures of the machine. Then yes if you look at the page for wheel cutting you can enter parameters and it will generate a G code but he left out things? Notice he has a picture of a complete wheel but the G code isn't making a complete wheel it's only cutting the gear teeth I don't see whereas the program for crossing out the spokes? Typically when you see people cutting gears once the teeth are cut most the time the spokes are cut by hand. Occasionally someone will mill them out but typically not with the program which seems strange if you have CNC capability for instance one of my friends fill it used to design assembly line equipment or things to make things. So his hobby was to continue to make tools to make things like clocks. Very interesting and clever clocks but his true fund was making the machines to make the clocks. Then machine is not controlled by G code like we would typically find today as the stepping motor controller he has was made a long time ago and the individual controllers used a textbased program. So the company had a editor you could write a program to cause each the stepping motors to do something. So basically once you figure out how to cut a gear he would just change the parameters for different size gears so here's an example of a gear as you can see we have the teeth and the spokes. Then we have a picture the machine which sucks because it would've been so much nicer if I could've taken a picture when it was cutting a gears so we can see things better. Then yes there is a worm gear stepping motor indexing this is a mini lathe and the indexing is at the end of the lathe head hiding. The basic operation of this machine would be brass sheet not cut to a specific diameter size not even round mounted on the machine. Then it turns and a milling cutter will cut the diameter. Then the gear would be cut with a gear cutter. The same mill cutter for the diameter although conceivably change the size I don't know but basically the same milling for cutting the outer diameter would be used to cut the spokes. I really can't remember how he did the center hole but whatever it was was very precise.          
    • Yeah I know the site and the creator of it.  the two video clips are good examples of the quicker method and a full tear down.  the quick method will work in many cases. But not always and not for all the different movements.  I strongly suggest to not bend the four tabs as was done in the first clip.  Instead there are three tabs that insert into the top plate, Much saver way as to not break a tab.
    • I found a motor that is 3/4 hp and another that is 1.2hp. They come with speed controller. So I don’t think I would need a wiring diagram. But I sure appreciate you offering your help! Do you think 1.2 hp would be too much for a watchmaker’s lathe?
