it's unfortunate that something that can look so pretty in a picture can turn out very poor. On the other hand it's an opportunity to make something much nicer. Like for instance when I'm doing this I'm looking at my computer and the desk I made so it fit the space that I had it met my requirements because I couldn't find anything that was suitable for a computer desk for me.
As much as I like my watch bench I would really like modifications like it would be nice to have drawers on both sides of the bench. The entire left-hand side is open and basically it's wasted space. when you're starting out it seems like the bench is a vast open space but it's amazing how fast it gets filled up and then you run out of space.
All of the watch mainsprings I'm aware of can potentially be hand wound into the barrel, some are just more tricky than others - some shapes or types of mainspring can be awkward regardless of method. Having a pre-wound mainspring is nice when everything is going to plan.
It should only slip to prevent overwinding, otherwise sliding and slipping of the mainspring in the barrel of an automatic will result in very low amplitude and poor running conditions or may not run at all. This why I never oil an automatic MS, even the slightest bit of oil drops the amplitude a clean dry spring with kluber on barrel wall yield 280+ without fail. For me at least can’t speak for others and not going to say my method is the answer. I would say a dry lube is best for a MS if anything. And as most say a lot of new mainsprings come with dry lube ready to be installed.
