I do as much as I can. Where I draw the line is boardwork, major soldering, or refurb (major cab or playfield). I agree that part of the fun is lifting the playfield to fix what I can. I feel bad for the people who don’t feel comfortable except occasionally removing the glass. I’ve seen pins with tons of burned out bulbs, and poorly adjusted fields...nobody plays those games because they are “broken”. Playing pinball is one facet of the hobby, but there is so much more.
