Absolutely gorgeous work with the escapement Tommy. I could watch it all day; the gap for the pin on the driven beat seems no greater than the pin itself, yet slips through like silk :) Congratulations. I love all the built in adjustment points you've given it...ramble, ramble, ramble....
Hello Tommy, Thank you for another good video... and a big CONGRATULATIONS on passing the 6,000 subscriber milestone... See you on the next one... Take care. Paul,,
Hi Tommy, Congratulations on reaching the 6000 milestone and many thanks for sharing your work so that an expat clockmaker in NZ can spend some virtual time in your workshop! This is the first time I have seen this particular escapement and I am much inspired to utilise it in a future build. Regards
Beautiful work Tommy, just love looking at it even when I'm tired from working on clocks in my workshop I always get new inspiration when I see you resurrecting a tarnished old movement back to life again clean and sparkling so back downstairs I go and finish my work with new enthusiasm and great satisfaction. Once again many thanks Tommy. Jim from AUSTRALIA. ❤😊
Great work Tommy, the level of precision in the escape mechanism is high. So much could go wrong with the manufacture, but it looks fantastic and is mesmerising to watch.
@@TommyJobson Hi Tommy. I've been thinking about this escapement and am considering having a go at making a clock using it. I was thinking of using a standard pin wheel escapement but like the idea of being able to use a shorter pendulum with an effective seconds beat. Do you have any links to where I can get some more information about dimensions etc?
I'm fascinated with mechanical devices in general, and just recently I've been getting into traditional clocks and watches. I just stumbled across your channel and so far it's amazing! The music box and clock sounds in your intro is a really nice touch.
A very impressive restoration of a very cool looking clock. That is probably the largest mainspring I've ever seen - I guess it has to be to power the clock for a month.
Thank you very much that is most kind. That’s not too big a spring, just the type that would be found in a larger dial clock or English bracket clock. You should see the spring in a Symphonium! They are arm breakers!
Nice to see you using the 'Perfect' handle screwdriver - I have almost a full set of H.D.Smith's, plus a few copies... most need a refurb of the wood inserts. Interesting to see that escapement working close-up, very neat - a really nice job you've done there, Tommy. Looking forward to seeing it fully faced.
Congrats on the subscriptions, well deserved 👍🏼 I’m a fan of all things horological, watches, clocks, stopwatches etc. I was trying to work out what wristwatch you’re wearing in this vid, can you share? Really enjoyed this episode, keep up the good work!
Fascinating video and superb work in restoring it. That clock with that escapement would make a superb project clock to make. Back in the 80s I made the John Wilding Congreve clock. Its a great talking piece but seriously horologically challenged. I would love to make another more accurate clock and this Perdu escapement looks like an ideal subject.
First off, Thanks for a wonderful channel! Secondly, I am fascinated with the Coup Perdu impulse escapement. Where can I find more information on this device?
Tommy, I keep looking at your amazing work on this and the escapement action. i built L.G. Browns design that has a Coup Perdu and to be frank it is not a robust design and wont run consistently (a bad feature for a perpetual clock). As I study this video a key difference is the escapement is of center to the wheel allowing the pallet angle to be steeper and in turn putting a larger impulse then my clock. Brown has all aligned along the center of the clock. Is this offset normal when using this type of design?
Congratulations Tommy on your subs milestone. A beautiful clock and some excellent workmanship you’ve put into it, you should be proud Tommy. I’ve got a question please, on my clock the barrel is identical to yours with the great wheel held on with four 8BA screws as plans. The great wheel is 8 and half inches in diameter. My question is has it ever been known for the screws to fail when fully wound with all that torque? It’s been playing on my mind. Thanks in advance.
Thanks very much indeed. I don’t think the screws would be likely to fail, even though the screw is only threading into a thin plate the force is in shear which is far less likely to fail. The chances of all four screws failing before breaking a tooth of the wheel or a pinion leaf are very slim i’d say.
Nice work Tommy, am I correct thinking it was a grease (the red) that you used to lubricate the barrel arbor to barrel and cap? If so do you have a rule of thumb as to when you switch between an oil or grease, like a pivot size or spring size (greater torque) or do you always use a grease at this point? I have maybe in error always used oil, but then i haven't really done many large barrel / large spring clocks. Cheers
You don’t miss a trick! The red is HP 1300 which is a high pressure oil similar to D5. I have moved completely over to fully synthetic lubricants which are very expensive but far better over time.
No because the pins on the other end of the pillars have to line up with their slots. I know what your saying, but often it actually looks better not to try lining up screws. As soon as you try the smallest imperfection is noticed. In horology screws are very rarely ‘clocked’.
I wondered the same at first, but knowing Tommy...I thought there would be good reasoning. When you say their slots Tommy, are we just talking of age related witness marks from the pins?
@@neilscragg2148 if you take a look at 19:00 you can see a witness mark that the pin is not aligned with, Tommy does terrific work and I take his point about screws not being headed on clocks but !
@@bryanlatimer-davies1222 if you look at 24.10 you can see the clock upright and the pins not in view, which you would have done from their postion at 19.00, I skipped forward...as I expected Tommy would have repositioned the pillars for the screws to be tight, and the pins aligning correctly. Also you can see that the top right pillar screw for example...had changed from a vertical orientation earIy in the video to nearly horizontal at a later point. I have personally witnessed Tommy's work and detail, I would have been extremely surprised if that was the case 👍
@@neilscragg2148 you are spot on with your observations as always! The first set of pins you see are long pins just to hold things together for assembly. These were replaced later on with shorter nice tidy pins aligned with the slots.
