Here's what I have for mainspring winders. The Watch-Craft sets do a lot. The Bergeon set handles others. If I can't get the job done with these I then resort to installing by hand. Pocket watch mainsprings go right into the barrel. Wrist watch mainsprings are more easily hand wound into the rings that new mainsprings come in (I save them), and then pressed into the barrels.
Some of the Bergeon winder slots have been modified so as to not bend the spring as it's being wound into the tool.

That's sad that you had to modify those Bergeon winders to make them work correctly. That set costs $1500 new!
