  1. Just picked this up, Boley Leinen. Anyone know how to adjust the collet holding tail piece. Sent from my iPhone using Tapatalk Pro

    Making a Balance Staff

    Also lined up the impulse jewel to the center of two arms and then drew the line straight from the jewel to the pallet fork pivot then placed the hairspring on the balance loosely to align with stud; while the impulse was perfectly centred with between the banking pins.

  3. Need to make a balance staff for a European picket watch. The old staff had both pivots broken off. First I disassembled the watch and removed the balance staff. Removing the roller table was the hardest part because it was a Three arm balance and my Magic Roller Remover would not work so I used the scissor type. I then determined the widest diameter of the balance staff and found a 2.0 mm piece of Blued Steel. I cut off 1 inch and sized the collet, and inserted in into my Boley Leinen Lathe. I then started to cut the Balance and Hairspring side by first using the old staff as a guide and marking the piece of steel with my carbide graver. I started cutting down the first diameter where the balance fits and simply cut and measure until it was snug but still room to stake it in place. I then cut the hairspring diameter next and fix and cut repeatedly until it was snug. I used a special gauge to measure as I went along. Once the part fit was good I worked on the pivot with the graver until I got it down to around 0.2 mm and then used a stone to get it to around 0.14. The rest I plan to do on a Jacot tool. I then flipped the part around with a different collet and started working the Roller Table side using the same technique. I Amos finished off the plate where both the rolled table on one side and the balance on the other side rest. Slight error in the description. I left the full part in and started working on the roller table side before cutting off the part and flipping it around...saves time. I worked on the other pivot as well and got it down to 0.14 with a graver and then a stone...on the Lathe. The final product looked great. I am waiting for a set of vintage pin gauges to get the pivot size exact. Will finish it off next week. Sent from my iPhone using Tapatalk Pro

    Making a Balance Staff

    Done and dusted. I shimmed the balance cock because I did not want to shorten the pivots and more and the pocket watch was running with good amplitude. Sent from my iPhone using Tapatalk Pro

    Making a Balance Staff

    More progress. As well, made a video on how to use Jewel Hole Gauges. So I staked the balance wheel onto the newly made balance staff, friction fit, and it fit really well. Very pleased . I then used the jewel hole gauges to determine the hole size and this the pivot size. Turned out to be 0.10. Now I need to burnish the pivots to that size, fit the part in the movement and once fit perfectly, I will add the rolled table and the hairspring. Sent from my iPhone using Tapatalk Pro

  10. Unusually finish them off with a Jacot tool just to avoid snapping off the pivot in the Lathe....chicken. I do have a jewelled ruler to measure the pivot size. I bring it down to around .14 in my Lathe and shave the rest off I’m the Jacot. Perhaps I can more brave as well. I did pick up a set of Pin Gauges:) Sent from my iPhone using Tapatalk Pro

    My first balance staff!

    I use 4 carbide gravers, two are 4 mm flat and round and two are 2mm flat and round. Found them on a speciality site and they are around 15 US each but worth it. I also have a few 5mm triangle gravers for the initial cuts. Sent from my iPhone using Tapatalk Pro

    What is this tool used for and how do you use it ? Sent from my iPhone using Tapatalk Pro
  17. About 6 months ago I picked up an Invicta Grand River and was really impressed by the quality of the case and look. It also had a Seiko NH35A hacking auto movement. So a few weeks ago, I picked up the Grand Diver 2. Here is the picture of this beast. It weighs about half a pound. Had the same NH35A movement, which I hear is reliable. I am an old diver, and this is definitely a dive watch. Retail on this was $856 US. I paid a lot less. Sent from my GT-N5110 using Tapatalk

    The thumb knob opens the mouth in the center and the side knob is just used to brace the other finger as leverage. The knob on the end is an unknown feature. No hole in the stake at all. I thought it would somehow be for studding a Hairspring ?? Sent from my iPhone using Tapatalk Pro
  22. I am wondering if i should reattach the balance cock assembly onto the bare movement and put the whole shebang into the ultrasonic cleaner and run it using basic jewelry cleaner. I have no other method of cleaning this assembly, unless i dip the unit in lighter fluid. Any suggestions? From Canada

    Cleaning Balance Cock With Hair Spring

    Big thanks, I did not know that. I would have dunked the complete balance and all in lighter fluid along time ago. I was Afraid of loosening the jewels. Darn. Sent from my iPhone using Tapatalk Pro

    Cleaning Balance Cock With Hair Spring

    Can you put a balance with impulse jewel shellacked in the roller table into lighter fluid without the shellac desolating?? Sent from my iPhone using Tapatalk Pro
  25. After servicing a South Bend pocket watch with a weak mainspring, I think the small amplitude and fast BPH on my 6139 is probably due to a weak mainspring and not magnetism or a dirty mainspring. So the question is; is there any way to remove the mainspring barrel on a 6139 without a full disassembly? And, where would the best place be to pick up a new mainspring?
