I'm replacing the balance staff on my Hamilton 992B. What size levers should I use to remove the hairspring. If you prefer a particular brand, I'd like to know that as well. If a different tool is better to perform that task, please let me know.

Thanks
Rick

I bought this "old school" vintage K&D hairspring removal tool from an online auction. It works like a charm. Looks like I should be able to use this on different size collets.
