Restoring a Mercer 10ths DTI

Hello everyone. I am back from work and in this episode we look at finishing up on a Mercer 10ths DTI restore. I began the work some time ago, and it has been sitting around waiting for me to finish it. No time like the present. Please note that I do not intend this film to be a "how to" for the repair of precision measuring instruments.

Hello everyone, in this video we are looking at restoring a Mercer 10ths DTI. This is a project I started some time ago and has been languishing in a box waiting for me to finish it. This film is not intended as a "how to" for this type of work. If you want that you need to look at the work of Mr. Bob Dixon that can be found here:- kzbin.info/aero/PLwzZw6FLeTREPtbrrjSrkNr8RQ3xmfwtF&si=w2G0vfAO6MgtQgoU

Just like to say brilliant. thank you. Carl

Thank you very much indeed Mark. It's comments like yours that keep me going. Because believe me, I've considered giving up a number of times just lately. Your comments and interest are very much appreciated.

good video..thanks for your time

Thank you for your comments and interest!

Good job finishing your project. I dropped a indicator once and played with it and got it working. It's people like you that show us it can be done professionally.

Thank you for your interest and kind comments. I am not sure about professionally! I tried to do the best I could with it. It still isn't perfect but the new spring should help. Thanks again.

Thanks for this video Carl . A proper "Have a go hero" stretching the abilities is the best way to learn . I also have been following John mills and of course the legend Bob for years . I have been fiddling with old mantle clocks for a while and when I finally get one to work properly I will do a video . Watches are beyond my old eyes nowadays . great job . Cheers Ade

No problem Ade. I enjoy working on small mechanisms. I am very pleased you liked the film. Yes, Bob Dixon is definitely the authority on this subject.

as a young man I was fortunate to visit the Mercer factory . If I remember correctly it was on Hanger lane on the north circular of London. It was the first time that I had ever seen a CNC machine . I am guessing early 80's . the facilities were eye opening as to attention detail and Quality expectations . Cheers Ade.

That must have been extremely interesting. Hanger lane, the gyratory system. Probably doesn't come across in my film but the sheer quality and precision inside the clock has to be seen to be believed. Thanks very much for your comments and your interest Ade.

Thanks Carl. Very enjoyable and something I can well relate to being a watch collector. Cheers, Peter

Thanks Peter. I'm told the method I used for removing the hands is the same as used by watchmakers. I'm glad you enjoyed the film.

@carlwilson1772 That's correct Carl.

Excellent. I have a John Bull 10th gauge with much the same problem. I'm.going to send it to Sainted Bob as my HAVS precludes fiddling around with watch sized components! Best wishes, Dean.

I don't blame you. I'm still not happy with the return speed of this one and I think the new spring will fix that. It wasn't too bad to dismantle and clean really. More like clock sized components as opposed to watch. The rebuild has been a long time coming. It was pre COVID that I dismantled and cleaned it! Glad you enjoyed the film.

I think you could safely add "Jeweler" to your CV now mate.... Great demonstration and great work with the camera for clarity. Really enjoyed that episode.

Thank you Tony! I'm not sure about that! Quite happy to have a go at most things. What I didn't mention in the film, and should have, was that I have an old book from the 1950s on Aircraft instrumentation which gave me some help and insight. That and watching Bob Dixon which showed me the way. Thanks again!

You made a nice job of that Carl. Not for the faint hearted, or those afflicted with sausage finger like me lol. Cheers, Jon

Thank you Jon that was much appreciated. It wasn't too bad a task. I'm fortunate to have some good small precision tools like Lindstrom tweezers and forceps. I also work with fibre optics amongst other things in my day job which definitely hones the fine motor skills. I enjoyed refurbishing the clock and I'm glad you enjoyed watching.

well explained Carl i have a very similar one not returning its basically new old stock, i have been avoiding it for ages so might give it a go when i have nothing to do cheers Carl👍👍👍👍 regards Kev

Hi Kev, glad you liked the film. Thanks for your interest and comments. As I said take a look at Bob Dixon's films over on Doubleboost channel. I put the link in my comment. A knowledgeable man who will keep you right. Have a go at your clock gauge, it's not as daunting as you think.

Excellent Video Carl, very challenging to film at that focal length! Enjoyed it muchly, but I shall not be doing one on my clock guages, they are working much better than my eyesight! Phil

Thanks Phil, I really appreciate your interest and comments. I'm glad you enjoyed it.
