A really helpful video Matthew for a common problem. It was good to see the sequence of work and the reasons for the choice of materials and cutter module. Glad you got round to repairing the larger piercing saw. That was a project in itself 😂
As usual, meticulous detail and most enlightening. I need a date wheel for my latest purchase (1760 Welsh longcase), but I don't have this standard of equipment! Where do these date wheels disappear to! There must be a huge stash somewhere 🤔.
Thanks for the video, but I wish you had shown exactly how the new wheel moves the date indicator. Also ... why is it that the missing piece of the mechanism is not uncommon in clocks of this kind? (I have just such a clock, also missing that wheel.)
I'm usually pretty good at this sort of math, but I have to admit I got lost at about 5:32. I suspect you're calculating something about a theoretical wheel that has the CD as its radius, which has the sum of the two wheels' teeth, and which meshes with a wheel that has zero teeth. Is the sum of the two wheels' diameters divided by the sum of their teeth a constant for a given center distance? Thanks for this thought-provoking and informative video.
Lovely video to watch very interesting and satisfying to see clocks repaired ill leave this kind of work to the experts😂. I have a Jmperator clock made in Brussels that appears to need a pendulum dont know if its something that i can make or rather leave to the experts but i do think it may need a suspension spring as well. How do i tell the difference
Is it a pigeon racking timing clock? It really depends how much experience you have with more straightforward clocks. If it is spring driven, you always have the challenge of getting the power off the mainspring first.
@@howtorepairpendulumclocks hi thanx for the reply. Looking at the back of clock there are 2 barrels for clock spring. There is a little swing lever through which a pendulum wire would go through(based on what i learnt from cuckoo clock.)but there is a shaft more above near top of back plate which appears to be the spot where the pendulum suspension wire would hook on. Im certainly no expert on clocks but would like to learn more. Im not finding any info on what the actual pendulum length and the size and weight of bob should be. However ive seen formulas to calculate this but no known variables to work from
Yers, to calculate theoretical pendulum length, you need to count the number of teeth on the gears between the hand and the escapement. You can also do it of course by simply beginning with a longer pendulum rod and gradually cutting it shorter. As for pendulum bob size, the mass of the bob is mostly immaterial as the mass is not part of the pendulum equation. Again, start with a piece of plasticine or similar and experiment. M@@jacqueso8424
@@howtorepairpendulumclocks thank you, the reponse and reply is much appreciated will start playing with the clock real soon as im eager to learn these things.
Great video our grandfather clock dim Cardiganshire Mid Wales probably 19th century has a kidney shaped slot in the face with figures which I think is the date.. but not connected
The clock has a low tone on 1/4, 1/2, and 3/4, as well as the number of hours is also low, and some of its parts (parts of the machine) need maintenance. The clock is located in Iraq - Baghdad. How much does it cost to maintain it so that I can calculate the shipping costs and that I only send the machine, knowing that the clock is working With three weights
Always learn something new on your videos
Thanks Mark!
Brilliant work Matthew! Thanks very much for sharing this. Lots of techniques described and demonstrated as well as an obvious pride in your work.
Thank you. Appreciated.
Nice job as usual Matthew.
Thanks Dell. Hope you are keeping well. M
@@howtorepairpendulumclocks yes still doing lots of torsion clocks for other clockmakers, have you done the one I sent you yet ?
@@torsiondell like many jobs, in the queue!
I will never in my life do one of these, but I love to watch this type of content.
Thanks Keith for your kind feedback. never say never! M
Thanks Matthew. I always enjoy watching your videos and always learn something. Please keep them coming.
Thanks Brian. Appreciated. M
Always something to learn from your videos
Thank you!

Thanks Ian. It only took me 10 years!
Thank you for sharing this-- truly superb workmanship!
Thank you, very kind.
Very well explained and filmed. Thanks.
Thanks John. Matthew
As always a joy to watch the master at work 😁
Thank you....
Thanks this is captivating and I am watching from 🇨🇭

Thanks for your kind feedback. Yes, thousands must have been thrown in the scrap bin. Great shame. M
beautiful video many greetings from Italy
Thank you. Appreciated.
Дякую вам за працю 😊❤
You make it look easy.

if you send me a couple of images via email happy to have a look. Matthew
