Hi everybody. I'm trying to learn this fascinating art. It's my first time and this is my first project. I'm tryng to service myself my 2836 -2, but now i find big troubles to install again the balance wheel. After i put in properly it doesn't engage the fork pallet and the escape doesnt move. I there a method to apply to insert the jewel on the balance right in the arm of the fork pallet? Any suggestion?
