Before fitting the hairspring, always a good idea to check the balance wheel is running true. Riveting on these split balance wheels can lift an arm sometimes if your unlucky. And some minor adjustment to re-true the balance may be necessary

Put it in a truing calliper and it looked good.

The way to prevent any misalignments is to rotate the punch while you are tapping the balance wheel onto the new staff this will help the balance wheel to be re-seated correctly.

BTW, what kind of steel are you using and what type of gravers? You have to be careful with steel selection and avoid any that undergo work hardening. They sell something called "blued steel" at many places that is typically horrible stuff for what we are doing. Best bet is to get annealed O tool steel and do the gardening and tempering yourself. That way you know what you are getting.

I’ll need to find some annealed O Tool Steel. Do you have a reliable source

Update. Had to re-shellac the roller jewel, then i staked in on my new staff. I then aligned the hairspring with the balance cock and the pallet fork. I put the lot together and it started running right away: with exceptional amplitude. However as i completed tightening the balance cock, the balance stopped. Too long a pivot on the top of the screen staff. Tomorrow i shall Jacot the pivot and start the adjustments48aedcffd969c76f3f3b079a503d0bcd.jpg6cbd0acddd3c1b28430e8495cfbf8d42.jpg6651d8d0f452306bdcfb1d5f5bec77ad.jpg04c9128c1ae9763a67c5b950b3a9f258.jpg

What you did ~works~ in an worker kind of way. If you blow a measurement on a staff, only solution is to start again. What you did would work on a clock, but centricity on a watch balance is too critical. By tightening the roller table in a staking set you've mangled the center and I'd be surprised if you got that thing even well poised. Like I said though, it will ~work~ but you've just forfeited precision and introduced positional timing variability. 

Worked and accurate

Honestly, once you've manufactured and fitted your own working hairsprings there's going to be no limit to your possibilities. Very well done indeed

Another adventure I’m sure:) I wouldn’t know where to start to manufacture a hair spring.

You said hairspring? Did you mean Balance Staff?

      Like losing Ranfft. That was a wake up call. We took his website for granted. Miss him terribly.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      By GuyMontag · Posted

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.

      Is the Roamer not a split stem? I'm confused on your how your case is put together. If it is a front loader where is it you are putting the case screws? I love me some Roamer, do you have any photos?
