Been doing my first ever proper clean of my IJ. Stripping everything off the playfield and disconnecting everything was scary, but I took millions of photos with my iPad. Now I am putting everything back, and even though I am following Garrett Lee's fantastic guide (that man deserves a medal from Indiana Jones owners), there are definitely times when you would wonder 'what's that screw for' or 'what's that random piece of metal - never seen it before in my life'. It's just a simple matter of flicking through the iPad sitting on the bench and the mysteries are solved. Then there's the ability to flick back to Garrett's guide or the manual. Overall I would say I couldn't live without it for any future jobs like this!
