Go do a job where you have to install a bunch of 30" spherical bearings, where SKF will send a couple reps to site just to make sure you're doing it correctly. That's where all the cool bearing installation tools will come out. Huge installation collars, removal collars (both with weird special wrenches), eccentric support posts to align the bearing, all kinds of stuff. The eccentric posts were a pretty good idea. I made myself a set after that job.
