Just to let you know, I just made a full movie on how to make a balance staff. I start with an old Waltham movement and show how to strip the balance cock down and then strip down the Parts right down to the old balance staff. Then I show the process of measurement and material selection, including the use of the tools. I then cut the complete staff including finishing the pivot ends on the Lathe. This is the most complete video I have made to date. I will post the link as soon as it processes in a few hours...on my “jdrichard01” YouTube site. Here are the end results and the camera setup. Very hard to do with a camera strapped to the Lathe.fdc36bbaf052eb48bdf5a7110b50b529.jpgb02ce5f7f80b083fd5411a05c6222e51.jpgece32388943e3c0bb89b49904326760a.jpg

Great Vid Richard.That square graver is great where did you purchase it and is it carbide. 

Precision Artistry, [email protected]
Bought the 2 mm (round and square tip) 4 mm (round and square tip). These are way more useful than the typical large triangular graver, although a 4 mm small triangle would be great for undercutting the flat spots on the rim of the cuts.

Thanks I will have a look. I have failed miserably making a new balance falling often at the last hurdle. However I have had a lot of success in modifying existing staffs. The gravers you are using should help.

The roller table cut is very hard so I really take my time. The pivots are also challenging. Using a stone to get the right final diameter of the pivot is the real skill. The rest is not too bad.

Thank you so much for posting this, I will be devouring it later. It's very timely for me in particular as I'm just starting out on lathe work and have started on the balance staff journey. And all I have achieved really so far is to find that I need a LOT more practice!

Instead of using gauge callipers why not, use a Vernier gauge it is a lot easier to handle. I cannot remember if you mentioned anything about taking measurements. I always measured all parts of the old staff and had those at the bench on paper to refer to if needed.  I didn’t find it a long video, it was extremely interesting and thanks for sharing.

It takes a bit of time and not cutting off to much material is the hardest part. I had to turn a friction fit staff into a riveted staff once because I cut too much. Also, cut the pivots down to .2 mm and then use a stone for the rest. Screw up one pivot and you need to start all over again.

Thanks for the input. I usually take all the dimensions first as well and love the pivot pin gauges, dormiens gauge(spelling) and the pivot ruler gauge. All seem to work.

deep bow for your work and sharing this, I know now that it will take me a lot more working on watches before I dive into making this....:Bravo:

Thanks for the input. Read a boatload of books first, then bought the two video sets, tasconni and John Trope(spelling): I’m on a plane right now:). The I found the right material and gravers that were sized right. I also bought some sharpening plates off AliExpress for almost nothing. I should do a video on the tools needed. I now have 10 lathes. 5 on borel stands and the rest are traditional.

Interesting jdrichard. I only have HSS gravers which work great but need sharpening on a regular basis. The only reason I have not purchased the carbide gravers is the issues with sharpening them. If I am correct the only way is with diamond wheels or laps.

A good way of starting is to make a staff about 4 times the normal size. You could start with something like a Swiza clock balance staff. Then work your way to a watch size. It helds to get to know your lathe and good pracrise with the gravers.

Managed to watch the first hour last night JD, very good stuff my friend. It's certainly given me some pointers on how to take my lathe work forward. I've read before that you can tell when you are turning well as you get swarf rather than chips from the material, so you are certainly turning well! Can't say the same for your singing though... :D

Very very funny. I am a guitar player though

Sheet of 2000 grit diamond plate. Buy on AliExpress cheap. Works really well with a screwdriver sharpener.

Just when I thought I was done, I was carefully putting on the second hand on the wheel and the PIVOT BROKE right at the jewel hole.da4feccddb09fb68a6b27e691eb0fdeb.jpg
Disassembled it to have a look and it was indeed broken, leaving the pivot on the second hand pipe.c6886df4459ad0aaa8b51a0770ef882b.jpg8c7c38509785ed0b13e9708082f8076f.jpgdaff378665e88ceabc9bd07047280ed8.jpg
So now I need to repivot the gear. Stand by for the next adventure....may make a movie as well.6d7081a9a33fdcd3f73772a95b2f4ad5.jpg

      Never and others. Yes like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Get someone local to tig it ,very easy fix and should only take a few minutes so probably wouldn’t cost much ,or failing that get it very clean and silver solder it. Dell

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, The winding pin is not split, well that's how it was when I obtained the watch. The movement is front-loaded and here's a picture of where the case screws are fitted. The face picture is before I dismantled it. Quick update.  I've always had a nylon ring sitting in the parts try that I wasn't sure where it went and left it to the last thing as I know it must be part of the case assembly. Anyway, looking at the picture in my last post you can see, just under the winding stem, a white-looking object, this is the nylon ring 🤭 So, I had to remove the dial again and replace the ring. Once this was all back together I placed the movement in the case and realized my initial problem maybe is not a problem as it looks like I can screw the movement back in the case and then place the hands as the dial is nearly flush with the outside of the case anyway so I'll be able to check for alignment. if all is good then just fit the crystal and bezel 🤔 I can't think of any issues with this approach but please comment if you think I've not thought of something. Another lesson learned as well. Take more pictures not just of the movement parts and location 😅

      I dont think mine is. Its an idea to have them all in one place if possible, then a quick screenshot will have them saved. Unless anyone has any other ideas of how to reconnect
