Jewelers tools like small screw drivers, pliers, tweezers, wrenches etc. Get a good spanner wrench, the cheap ones are junk. I also have some surgical tools like forceps for holding on to small parts. I use lithium grease (mostly on old projectors and movie cameras), sewing machine oil, Ronsonol lighter fluid, isopropyl alcohol and locksmith type graphite for lubricating. I use a very fine artists paint brush to apply grease without getting it everywhere. Cotton swabs come in very handy as well. Also work on a towel to keep parts from bouncing off into oblivion.
