Skvělý! děkujeme za vaši milou zpětnou vazbu. Doufám, že obsah povzbudí vašeho vnuka. Matthew

Eu tentei fazer esse dias e me deparei com essa dificuldade de fazer espaçador de tempo e questão de ir regulando até ficar bom o melhor para aprender tem que fazer..

Very enjoyable hour spent watching this. Thanks for your efforts.

' .. go round the escape wheel looking for rouge teeth ..' Therewa, how good is that in Northern accent! 😁

Top work

[@Golfer-rn7lh]

You talk about center distance between intermediate wheel and escape wheel then apply that to escape wheel and pallet arbor???

[@openclockclubarchive325]

Hi. Thanks for your feedback. I havent re-watched the whole thing yet. From what I see I show the escape wheel to intermediate wheel centre distance as an example of centre distance (11.54). When I show the drawing, I hope I make it clear that the centre distance we are interested in here its the escape wheel to pallet arbor? (12.58) Apologies if this isnt clear! M

Really exelliant study

[@openclockclubarchive325]

Thanks Jon! Let us know if there is anything specific we should cover. Matthew

[@MK-ge2mh]

Great lecture! Yes, please, more talks about escapement design. I would also like to ask you for a reference to a book which contains very technical pendulum escapement theory with all of the geometry, trigonometry, calculus, and physics. I'm sure there must be a book with that, but I've been unable to find one.

[@openclockclubarchive325]

Thanks Michael for your kind comments. Regrettably clock books do not seem to be written with the reader in mind... (don't get me started). Daniels (watchmaking), Rawlings and Gazely will get you started but you will have to work quite hard to get what you want I imagine. You might like to try the Horological Science Chapter of the NAWCC. Some great brains there and I'm sure they can point you in the right direction... I'll do a bit of a follow-up next week once we have the Enfield movement back in its case! M

[@openclockclubarchive325]

Soon I will do the same exercise with the dead-beat with equal locking and equal impulse. M

[@MK-ge2mh]

@@openclockclubarchive325 Thank you for your reply. I am wondering something else from your video. When you set the depth of the pallets, what is the effect on time-keeping and amplitude when the pallet depth is deeper that it should be, but not so deep it stops? This is interesting because I have two movements with strip anchor escapements where after fully cleaning and installing new mainsprings, I set their pallet depth as deep as could go (couldn't be set so deep that it stops) and am wondering if this might be where the problem is. They both keep perfect time for the first 2 1/2 days and then dramatically lose time after that where by the end of the week they are 5 1/2 minutes slow. After watching your vide, amplitude should be greatly affected by pallet depth, thus circular error must be greatest in this case.

[@openclockclubarchive325]

@@MK-ge2mh Hi Michael. Good question that I will tackle on Saturday. Circular error would make the clock lose at the beginning of the week and gain later on. Did you replace the mainsprings? If so and you have the old ones, if they are not broken, re-fit them. Your clock now is being over-driven. The anchor recoil escapement has a positive escapement error. When you drive the clock harder, this becomes more pronounced and swamps circular error. new mainsprings will also prematurely wear the clock out. My advice, only replace mainsprings as a very last resort if even then. M

[@MK-ge2mh]

@@openclockclubarchive325 Thank you for the advice! I shall try that. I remember you mentioning that in a video, but I had already ordered them and wanted to try new ones because it was losing time similarly. Now it appears to be exacerbated. Anyway, I'll go back to the old ones. Thanks again!

[@kwacz]

I have a pendulum controlled clock and it makes a knocking sound instead of ticking, then fades to a regular ticking then fades back to the knocking. Reducing pendulum swing has no effect. It must be coming from escapement but dont know for sure. Pendulum definately not hitting anything and clock keeps perfect time. Any ideas here what's going on?

[@readrepairs]

Hmmm, interesting. I had a similar experience a couple of weeks ago. Imn my case it turned out the suspension spring was moving in the back cock slot making a double ticking noise. The movement was barely perceptible I put a small amount of heavyish oil on it and the sound disappeared. Did you put oil where the crutch impulses the pendulum rod? Also, check the backs of the pallets are not glancing the escape wheel teeth. To check, increase the centre distance between the escape wheel Arbor and the pallets ever so slightly. If the clock has one of those relatively lightweight pendulum bobs, check it is not moving on the rod. Hope this helps

[@kwacz]

@@readrepairs thanks. I need to do a complete disassembly to clean inspect anyway but its good to know what to look for ahead of time. You might be on to something.

[@dougmaz1]

Hi ..I’ve just came across your video and I’m so pleased with it. I live in Australia and Iv been repairing clocks for a long time. All the clocks I’ve repaired for people are still working I build model Steam engines from scratch for a hobby but very interested in clocks but I feel that I’ve been plodding along using trial and error to get them working. But now I’ve found your channel I’ve learnt a fair amount on the workings of clocks. How do I join your club? It’s my number one on KZbinTube. Doug

[@openclockclubarchive325]

Thanks Doug for your kind feedback. I'm glad you found the series of use. The Club was a lock-down initiative so it only ran for a year. I dont know whether you have found out other to clock repair related KZbin channels? READ Repairs and How to repair pendulum clocks... (links below). You may find them of use too. If you have any questions, please shout. Good luck too with your clock repair progress. Matthew. kzbin.info/door/QAVLubQcXt3QbzlchD0Wkw. kzbin.info/door/q25FhgQkNLeNJOBcw9BOlA

Good video. I am trying to make a new pallet for an old longcase clock. In your video you repeated say "it's covered in 'our book'" but you never indicate where this msterious book can be obtained. Any hints??

Hi @Yobbaray. Apologies for not giving a link to the mysterious book. Here is the link. At the moment it is only available on the Kindle reader as the first edition of hard copy sold out. www.amazon.co.uk/repair-pendulum-clocks-Getting-started-ebook/dp/B08NYWVC7Z We are re-printing later this summer so please keep an eye on our website for updates!

Was following Gazeley trying do design a recoil escapement but the description of the second pallet gets VERY vague, and also the description doesn't completely match the drawing in the book even though it refers to different points and line markings in the drawing :/ This was a huge help! Thanks!

Escapement!

24:42 Woo - a lot of technical terms in a short time, all having to do with the fundamentals of the history of the pendulum. Some pointers may help: Christiaan Huygens: en.wikipedia.org/wiki/Christiaan_Huygens; Isochronous timing in horology (definition): en.wikipedia.org/wiki/Isochronous_timing; Cycloidal Cheeks are shown in the Wikipedia article on Huygens' "Horologium Oscillatorium": en.wikipedia.org/wiki/Horologium_Oscillatorium; The cycloid curve and its relationship to an isochronous pendulum (I just look at the pictures - the math is messy): en.wikipedia.org/wiki/Tautochrone_curve. I'm sure there's a more concise page about all this, but this was the first set I found on a quick search. Such cool stuff! Thanks again for the wonderfully detailed and practical coverage how an escapement is designed.

I have a Ridgeway model 225, date 8/27/86, Movement CC-1161-853-114-CM. It will not stay in beat, I have found that the anchor escapement is loose on the shaft. I can rotate the anchor slightly and it will run just fine, then all of the sudden it will slip and get out of beat again. What is an acceptable way to secure it to the shaft? Thank you Hager Hay

How is the friction between the pallets and the crutch (leader) achieved at the moment? Happy to help. You might like to join our Facebook group (How to repair pendulum clocks) where you can post images and loads of people to help.
