Timegrapher question

To get the proper meaning of your question you have to ask the question correctly? Seconds per day means how many seconds in a day a timepiece is off. A Timegrapher Measures the Ticking sound in a watch averaged over a very short period of time and it makes a prediction of what the watch will do over 24 hours.  So using your timing machines/timeGrapherYou can regulate your watch hopefully to a few seconds per day. Then the only way to verify whether the timing machine is right is watch the watch over 24 hours or even better average over several days. Rolex averages for their timekeeping over three days at least to come up with the average seconds per day.

Making allowances for a secondary modern boy, I hope this question isn't too simple, but what does 'seconds a day mean'... is it over a 24 hour period?

I’m also a secondary modern, and also requiring allowances... so I understood your question precisely. I think others across the pond were baffled though [emoji3]

    • Yes, as watch repairers we never ever use force, we use percussive persuasion! 🤣 
    • I have a barrel bridge arbor bearing that needs a slight reduction. I have never closed a barrel bridge arbor hole before and my staking set has a very limited number of doomed punches and most of them are too small (go through the hole) or too short to fit in the lower section of my inverto-style Boley & Leinen staking tool. So, I'm considering ordering a few doomed punches from CousinsUK. My question is what sizes I should order? Is there a rule of thumb relating to the hole diameter? I too worried that reducing the hole size would increase the end-shake. Especially as Kalle Slaap talks about end-shake at the end of the video at 7:43, but then he just glosses over it by saying "You can just gently push the material back in", which I don't get at all 🤔 Anyway, I feel a lot less worried now after having seen @mikepilk's excellent illustration. Thanks!
    • If you have access to a 3D printer, here is my design I did a few weeks ago:  
    • I finished my polisher yesterday, and just tried it out. I'm surprised how easy it is to get a good result - just a couple of minutes. I thought it was going to be more difficult - a nice surprise as most things in watchmaking are harder than you expect. I bought self adhesive 3M lapping film https://www.cousinsuk.com/product/film-lapping-3m-261x266x , 9, 3 and 1 micron, and stuck it to sheets of glass. The 9 micron is course enough to remove large scratches.  I'm glad I used the M6 thumb screws as the large heads allow for small adjustments.
