God this takes me back! My Grandfather was self taught (but certified) horologist, I spent many hours as a child watching him work, at least what I could see over his shoulder especially on ladies watches!. He often made replacement parts such as this on a very small lathe that was originally treadle driven. That was 45+ years ago, wish there has been video cameras available
That is fantastic work your very talented. And I thankyou so much for these informative videos. Please keep making them. And do not be upset buy the thumbs down. Envy click. Ur skill is to hard to except.
Making a part that is .16mm (.006") is difficult. Most of the pivots I have seen are around .1mm (.004"). The problem I had, when I was trying to figure out how to do it, was having the pivot break off once the diameter was around .3mm (.012"). I know from struggling through the process myself, the master watchmaker in this video spent a long time learning how to do this. david
I have over the last sixty hears used my graver the other way up, and have never had the troubles you mentioned also I have never had the screaming and chattering that you get. I don't know if it's the bearings in you lathe or the collet you are using is not gripping the blue steel parallel or because the way up that you are holding the graver, whichever it is will reflect on the finish on your work. When I turn up a balance staff all you can hear is the motor, one other thing, I might have missed I didn't see you undercut the balance seating for the riveting of the balance wheel. I have been in the trade as a WATCHMAKER for well over sixty years.
I've tried it both ways and mostly work with the face down. While I don't have sixty years experience and in fact am a relative newbee, I do think many people who work face down have problems with the graver getting caught under the work. I do work face up when I want to work more precisely and take off less metal and I find I have more control as well. Like you I don't get the chatter I heard in this video. I was taught to "abhor" chatter. Thanks.
Hello Maurice, great demonstration. When you use your graver "upside down" do you also run the lathe "backwards" or the usual way, towards you ? Thanks, Mike
G'day Neekon, I know it's been quite a while since you asked the question, but yes, the lathe is run in the normal direction towards you. It doesn't matter whether you have the graver 'right side up' or 'upside down' :) Cheers
yor not a mechnic doesnt matter to know that or not, you get to make a course of turner to understand all of this stuff, or an watchmker course ,,, in the svhool not online...
Hi Danny Maurice was using an 8mm watchmakers lathe. 8mm refers to the diameter of the collet that locates in the lathe. The collet size (workholding diameter) you need depends of the blued pivot steel you are using, it should be as a close a match as possible so that the steel is held firm and true. If you have a watchmakers lathe you only need a basic collection of different collet sizes to cover this sort of job. If you do not have a ful set, it is not the end of the world as pivot steel comes in a variety of diameters; you can buy the steel to suit your collets. Hope this helps
+SLBBHI Horology The man who worked on my pocket watches for years died last year he put in a balance staff and clean the watch for 100.00 , done all the Amish guys watches as well , I work in a machine shop and use a big lathe for years , so I bought a watch makers lathe and a set of collets just to see if I could maybe do some repairs myself. One man in Georgia asked 400.00 for a staff clean , I know it's a lot of work , but I can't spend 400.00 on a 75.00 watch.
Very impressive considering the dimensions. I am a little surprise at the use of the fingers occasionally being put on the work-piece to clean it. Is it not dangerous considering the minute shavings coming off, that can enter the skin? May be the shavings are soft considering how the work is being done. Congratulations for your skill and perseverance to achieve quality work.
Thanks Maurice. Your video is very revealing. I have been practicing this for a fair amount of time and am still plagued with problems most significant of which is to maintain centering on both sides. Your reference cut was a revelation! I'll try it. Turning between centers is, frankly, a pain and requires dogs, etc. which are awkward. Am very interesting in the cardboard tray you have under your tip-over rest but I can't see it clearly. Also, where do you get "blue steel" stock? Another major problem I've been having is bad stock; it's either too soft or too hard. Thanks.
Sir, would you demonstrate the adjustment of balance spring alignment with pivot of French carrige clock. I am in trouble to adjust it many times but disappointed.

Lovely series Maurice, thanks for posting.
dont do this at home
Thanks for confirming that you can eye and mark reference points on the blank with the graver. Hard to convince students that I am not crazy!!!
Great job! Thank you very much for show us this video. Regards.

hi, i want to ask you what are the knives with which you cut the steel? from vidia, steel fast?
Excellent video. Very informative. A little disappointed not to be able to see the staff completed.
Hi, I know over the years there has been a lot of discussion over which way up to use your graver,,
I have over the last sixty hears used my graver the other way up, and have never had the troubles you mentioned also I have never had the screaming and chattering that you get. I don't know if it's the bearings in you lathe or the collet you are using is not gripping the blue steel parallel or because the way up that you are holding the graver, whichever it is will reflect on the finish on your work.

Looks like the same lathe I have Lorch schmidt
What size collets are required to make this staff?
