Turning the staff out on the lathe isn't that difficult because of the special carbide cutters I ordered and I am able to pretty reliably turn the balance pivot down to around 0.13mm without it breaking every time. After getting to this dimension I burnish down to the final diameter with the Jacot tool (on this staff the pivot diameter is 0.11mm)
All that remains for this project is to cut out the old bent staff then rivet this one in. It has been a fun challenge and I am looking forward to turning out more in the future.
