Do you have any tricks for installing new mainsprings, particularly the new ones that come wound in a sleeve or washer? What I have done for years is, while holding the sleeve I use a screwdriver and slowly press along the outside of the mainspring pushing it into the barrel. I feel like there is a better way, but anything else I have tried, has resulted in a mainspring that doesn’t completely go into a barrel, with an outer coil sticking out. Any advice is greatly appreciated!
I find that the sleeve for the 550 series is never small enough for the barrel, causing the outer wind not going into the barrel (like you mentioned) So I unwind the mainspring out of the sleeve and then wind the mainspring manually into the barrel. I use powder free nitride gloves when handling the mainspring. When the sleeve is small enough for the mainspring to be pushed straight into the barrel I press it in with a plastic stick. One can also use mainspring winders, but I never quite took to them.

Hi Brandon,
I find no flaw in your technique:)

Fantastic! Thanks for your advice (as always)!
