Excellent example of useful craftsmanship and a creative way to solve this problem without the difficulties of finding the right drill from a trader. Thank you.
@@howtorepairpendulumclocks Anything involving the repair, restoration and making of clocks. Books can only provide so much information. Videos such as yours provide the equivalent of hands on instruction.
In the field of heating and ac there is a gas orifice bit drill set that can be purchased for around 300.00 and the bits are so small you need a good eye loop to see them. Just a thought , but not to take away from the craftsmanship involved, excellent job. By the way, the bit set is made by Anderson and Forrester.
Great video Matt. I have used drill bits that are the diameter of the pivot and then cut the end of the drill bit off to use as the pivot. But I dont repair pivots too often.
Yes. Quite a few people have done it with varying levels of success. As a broad observation, the slower-moving, more heavily loaded bearings respond better to caged or roller bearings.
Really useful video. I made a spade drill - and it worked!! I would love to see a video on softening the arbor prior to drilling, especially the the end with the wheel attached.
Thank you for your kind comments. There may be something over on our LIVESTREAM RU-vid channels. Noted. Yours Matthew ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-L2UmavuZ86s.html
Excellent tutorial! I have wondered how such drills have been made, and mine have always been much cruder than that, tho they worked to a course job. I look forward to trying your design!
@@adiletk.3811 Yes! A great idea. Id the the very best way to begin is to buy the book 'Watchmaking' by George Daniels. It tells you everything you need to know. www.abebooks.co.uk/book-search/title/watchmaking/author/george-daniels/
Je n'ai jamais essayé ça. Pour une utilisation dans le petit atelier, une flamme à gaz est peu coûteuse, flexible et relativement facile à contrôler. Comment fonctionnerait l'induction ? Oui peut-être à l'échelle industrielle de la production ?
@@howtorepairpendulumclocks On trouve sur Internet de petits systèmes de chauffage à induction qui fonctionnent sous basse tension, en toute sécurité (aucune flamme) et qui pourraient correspondre à votre utilisation, faible masse à chauffer ; ce genre là: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rQGKJw6PWh8.html
Hi Tiny. Yes a lathe or turns needed to drill the hole. The pivot 'should' be a good enough fit to tap in. I think the old school used to put a bit of oilstone dust on the pivot to give it some bite. Solder should not be needed but maybe stud lock for security if the pivot is a very close fit. If the pivot is loose; start again. M
I have 12 clock drills from an estate sale purchase. I won’t use them. They are labeled PM - T47. I’d be happy to send then to someone who can use them. Let me know. Thanks,
You can try but it is by definition really difficult to anneal to turn and then you will need to harden it again. With HSS you would have to grind the whole thing with a tool grinder I suppose. Try annealing a piece an see whether it can be filed or turned. I suspect not but an interesting experiment. Plain carbon steel or 'silver' steel would be ideal. M
I would love to see you cover the basics of material hardness for clockmakers. I've put together my meager knowledge in a post (needhamia.com/clock-repair-my-meager-knowledge-of-the-hardness-of-metals/), but it's woefully inadequate, especially when it comes to stones. I think you've covered it all in bits and pieces, and a single overview video would be wonderful.
Hi Bradford. I will certainly continue to discuss these issues and challenges in relation to clockmaking. My 'knowledge' is based on experience though and I would be the first to say I am not a materials scientist. When I started I read a book by J E Gordon, The new science of strong materials. It is a bit old fashioned now but still worth a read. Just read your post. Please continue e journey and continue to share experiences. M
