That’s awesome you are so skilled I couldn’t imagine trying to machine little things like that I just don’t have the patience or steady hand lol great job thank you for sharing
Junghans used many different types of bobs on their clocks, They didn't fabricate their own bobs. They had their design fabricated by other manufactures, so many of the same movements will have been fitted with similar but different looking bobs.
Good morning Mr. Martin Master Clock Maker; Oh my what a cute little mantle clock. The Junghans Westminster Mantle Clock is simple yet elegant . The small chimes sound great. Very Nice engineering update to the pendulum, speed adjuster. Oh my, your parallel vice is just as snazzy as the clock ! Best Kristy
Someone may have put an incorrect pendulum rod in the clock. Not sure, since it was purchased at an auction. Sometimes people will do this sort of thing just so it can be advertised as a working clock.
Great clock! It's a shame pot metal was used for the pendulum bob and your right about that material. Pot metal was also sometimes used for wind up phonograph tone arms and reproducer heads.
I have repaired pot metal items using liquid urethane and vacuum chamber to force the product into all the compromised cracks. The urethane stabilizes and seals the pot metal from the outside elements and stops its disintegration.
Muito boa tarde mr. James Martin, o trabalho que executas com fidelidade e guardando toda a originalidade da máquina, bem a forma meticulosa no trato com as peças requer um conhecimento tecnico, afinidade, interesse, denodo, perfeccionismo traz a lume o excelente profissional que és, receba a minha admiração e ao mesmo tempo conferindo-lhe os meus mais efusivos parabéns, saudações.
Hello Sir. The Junghans Quarterly Chiming Clock , which is unique with respect to removal of main spring barrels. It's in intact condition with respect to cabinet and the movement I think so. Great Restoration Work.
Another spellbinding video James. So much skill and a very nice clock. Thank you for sharing. Tiny parts sure lend themselves to the metric system, especially when having to make drawings. I use it daily on big stuff too, papermaking machinery.
Hi Mr Martin, Thank you for another great video, my question is with such beautiful works of art clocks you receive is there and trusted conservators of wood and finishes that you know and Trust? Rather than see these wooden structures disappear like the wooden ships of old?
I don't know of any trusted wood conservators, main issue we see on these lacquered wooden structures is that wood expands and contracts with heat, cold and moisture exposure through the years and the lacquer doesn't so the lacquer ends up cracking.
My wife agrees with yours... Those louder ticks when I was on the lathe is the timing machine that was hooked up to a movement. But yes, I have multiple clocks running at all times, need to test them before returning to the customers.
please james for some reason my hands are loose not thw mand it self but the wheel and shaft its on...i gets stuck easliy and the clocks stops before stricking... the clock runs the pendulum swing the clock just stops wheres the point where the wheel in frictioned on if you know what i mean
Minute hand is held on with a taper pin and washer. The minute hand and cannon pinion get its tightness from the snug fit-up the taper pin and washer puts on it. Add a washer or cup the washer slightly more to get a snug fit when the taper pin is installed.
@@jamesmartin5370 very glad you replied but thats not my problem... where does the shaft the minute hand is on get its tightness...you know where you set the time...that kind of tightness...where the minute wheel connects to the movement
The minute wheel is the wheel and pinion to the right of the hour wheel, it drives the hour wheel and cannon pinion, its mounted on a stud. Cannon pinion is what the minute hand mounts on. The center wheel is the center shaft the cannon pinion slides on to, it has the hole in the end for the taper pin. I don't remember on this model for sure, but a lot of them have a clutch system on them some in front of the front plate and some just behind the front plate. Some clutches are a coil spring and some are a curved compression washer. Same model of movement used different systems from year to year, they were always changing small details. You will need to inspect to find.
@@jamesmartin5370 james thanks i will have a closer look but ever since you wrote back the clock has been going great since...what do you think about the value of these? i got mine for 15euros which is 17dollars it had a broken mainspring for the strike side which i have fixed... mine was made in 1941
A fair amount, there are many clock companies who have hermle fabricate movements for them, then they just install them in their cases. Do you have one you are working on....
My interest was piqued when I saw that crummy looking bob. I restore vintage radios as a hobby, and the tuning dial drums on some older radio chassis were sometimes made of pot metal. They tend to de-laminate just like this bob. I'm glad the practice was short lived. Pot metal really is a crummy building material!
هذه المهمه كانت صعبه جدا" ولكنك جيمس قد تجاوزتها بنجاح وتفوق..تحياتي ..
Thank you, James. The clock is running great!
Good to hear, should be trouble free for quite some time for you...
That’s awesome you are so skilled I couldn’t imagine trying to machine little things like that I just don’t have the patience or steady hand lol great job thank you for sharing
To be able to machine free hand when most would want/need to use a tailstock on the lathe.
Brilliant work James!
Thanks David
Enjoyable to watch, especially your attention to the bob and pendulum rod.
Junghans used many different types of bobs on their clocks, They didn't fabricate their own bobs.
They had their design fabricated by other manufactures, so many of the same movements will have been fitted with similar but different looking bobs.
It’s always a joy to see you bring so many disciplines to your trade and the care with which you take

Nice work. I dig that vise and original label!
I use that vise a lot, I see them for sale from time to time.

Thank you, Sir, I didn't know that was possible.
Nice episode.
Better to have one thing well exposed than everything a little.
It's always the Dutch who have to put their stamp on it (just kidding).
Superb Sir

Good morning Mr Martin and beautiful clock
it would have been nice to see the various phases of the work
Another spellbinding video James. So much skill and a very nice clock. Thank you for sharing.

Excellent work, beautiful watch with a pleasant strike. Thank you for telling us about your instruments, it’s very interesting.

And I would say the 751 on the bottom dates it from July of 1951
Good eye, yes its the date.
Date on the movement is written as 517 odd they didn't use the same sequence on the case.
@@jamesmartin5370 yes that is weird, and have you ever worked on a Revere Westminster chime clock?
My wife says the ticking in the background would drive her nuts, I say it would be soothing
My wife agrees with yours...

They are like most items, value is based on supply and demand.
I am focused on fixing timepieces and have never gotten into estimating values on them.
Hi, mr martin do you know much about the early hermle movements?
A fair amount, there are many clock companies who have hermle fabricate movements for them, then they just install them in their cases. Do you have one you are working on....
@@jamesmartin5370 no but I'm curious if the barrels are removable without disassembly like later hermles
They are like many other German movements, their design allows to remove mainsprings without separating the plates.
@@jamesmartin5370 thank you so much
