Good day to you all. I'm deciding to ask for help because I really can't manage it by myself. For the life of me I cannot understand how to set the balance assembly back into position after having replaced a broken escape wheel. I'm working on a Lanco/Tissot 782-1 movement, I had already removed/replaced the balance before and I haven't had any issue. Now I just can't seem to get the balance oscillation working. The wheel seems to stick or isn't turning freely. I have spare parts and checked 2 or 3 different balances, I checked the staff & its pivot which are not broken, the roller jewel isn't broken either, the balance pivot hole is not clogged nor does it seem widened, and the pallet is in working order (I checked the escapement by arming the mainspring a couple of clicks then manually oscillating the pallet with a wood pick, everything runs perfectly). So it seems the rest of the movement is okay, the issue lies with how to place the balance back into position. I checked lots of tutorials & videos, Mark's included and I'm always quite astonished when I see how watchmakers and repairmen handle the balance, even if the hairspring is fragile even professionals seem to handle that part somewhat roughly. I take the greatest care when manipulating that part (and others) but no matter how I set the wheel&pivot back, the movement doesn't seem to run. Is there something I'm missing? Should the pallet be positioned specifically when replacing the balance? Should the roller jewel be placed in a specific setting versus the pallet fork as well? Everytime I tried before those things didn't seem to make a difference, so I'm really wondering what's wrong here, considering I tried several balances with different plates and different pallets, I can't understand where the issue is. I guess my question is: as tutorials don't usually give out many details about how to lay a balance back down into the plate, what should I take into account and what are the exact right steps to perform to ensure the balance will run smoothly ? Thanks for your help, I'm getting desperate here :-/ Laurent AKA HardTop

Hello! I have a question, if I may: is there any way I could exchange the staff on the left with the one on the right? I would need to push out both of them and push back the good one on the left pallet fork. The staff is 0.4 mm and the pivot is 0.12 mm. Is there a stake (4.7mm ones) that small? I need to change it because the end fork is damaged (don't know if you distinguish in the second photo). Thank you, Bogdan
