Camera Maintenance and Repair - Books 1 & 2’ by Thomas Tomosy - AmherstMedia, Inc (search Amazon photo books section)
If in doubt about the purity/non-streaking characteristics of a solvent, simply try it on a mirror first.
Acquire a coupl'a representative junk lenses and bodies and totally disassemble 'em
with no expectation of ever restoring 'em to proper working order. Save all the screws, springs, rings, and other loose parts for future use and keep the carcasses around for reference. What you learn doin' it wrong the first time is called hands-on experience. (You'll also gain a lot of respect for the folks that used to conceive, draft, manufacture and assemble this gear without the help of computers or space age plastics.)
Do related word searches and study tool and hardware catalogs so you have the proper nomenclature for 'stuff'. Now that you're aware there's such a thing as a JIS cross-point screw and driver bit you also need to know what it looks like, where to get it and why you'll need one. Where do you find a replacement for that 1.2mm ball bearing that rolled down the rabbit hole? Will the tip of a ball point pen provide a useful substitute, or not? Do you need a truss head or a pan head replacement screw? What are the common thread pitches in camera lenses?
Squirt canned air on a soft,
nylon artist's brush to give it a static charge to help pick up dust. Or, just rub it on the cat.
Naptha (dry cleaning fluid) is useful in place of lighter fluid as a grease solvent - 's with the paint thinner back in the dark corner.
That band of rubber they wrap around your arm when they take blood makes a good grip/band clamp when unscrewing lens barrels.
You can make custom spanner wrench blades from a hacksaw blade with a bit of filing.
A light coat of 'rubber cement' provides a friction surface and can be easily removed later. That way, you may actually get a grip using those crutch tips and wash basin plugs.
And there's also that magic Indian incantation used to begin and end all lens maintenance projects: to be repeated seven times aloud - "
Owaa-tayfoo-liam!" .
