Very relaxing. Until impossibly small $15 Incabloc springs start flying around the room. I'm convinced these sublimate into a vapor the moment they fly out of view of your loupe.

Not relaxing to me, like the YouTube videos. It is difficult and frustrating. It is very easy to wreck things like brass threads. Often lots of things are seized up on anything more than a few years old. Fun all the same.

If screws seem seized up make sure that your screwdrivers tips are properly shaped.

I do, I have a fine whetstone. I agree, properly sharp/shaped screwdrivers make a huge difference. I think I need a better roller sharpening guide, and lots more stuff. :)
