Balance staff turning without lathe :)

Thank you very much for this. Re: 1. I've so far found that this one needs something thicker than 2x kitchen foil (another suggestion in that thread)! 2. I've been checking where the roller needs to be in relation to the wheel, the hairspring stud/arm & the pallet fork to try to get it right first time. 3. Does one raise notches at both ends of the tube? 4. What is a "driver roller sharpener"? -
Hmm, if it is sitting that low I am not sure I would blame end shake (which would be to blame if you turned it DU and the hairspring touched the balance cock). If it is sitting so low that the balance rubs on the pallet bridge I would verify that the balance arms are not dished downward and also that the lower balance jewel doesn't have an issue such as being chipped. Or the balance staff is actually too short, which would have caused your earlier end shake problems too. If you install the pallet bridge without the pallet fork and install the balance, is your free oscillation still good or is it immediately bound up on the pallet bridge? (I have an elgin watch like that where someone in the past ground down the pallet bridge significantly) Yes, you'll need to rotate the hairspring but deal with the pallet bridge interference first. -
Ok. So given that I had free oscillations DU/DD for roughly the same time, I reassembled with the pallet fork and bridge underneath, and now I can see two more problems. 1. The arms of the balance are nearly flush with the pallet bridge. Bad. I can speculate as to why…the end shake still looks to be too much. Maybe other causes as well? 2. The balance doesn’t spin freely. In the resting position, it looks like the impulse jewel is outside the jaws of the pallet fork. Not by much, but still outside. If it needs be inside in the static position, then I’m guessing I’ll need to rotate my hairspring collet to change orientation by a few degrees. The journey continues… -

Andy, why you betray me? I may have good news. I'll share later! I have contacted an old watchmaker from my town, and the guy has it all. He is offline, so no parts are available to purchase, but he offered to send one for less than 10 USD, which is great. I'm now checking if he has an oscillating weight as well, to close up all that I need to put this movement to work. Thank you all for the support. And if any good soul finds a video of the assembly process of this stem and crown, it would complete my day!
