I had a 1973 Model, (Emerson Electric) Craftsman that I used for years. Granted, the fence was hard to adjust, but once it was fine-tuned, it worked (and is still working )fine. My son uses it, now. The key was to completely release the locking mechanism, so that there was absolutely no drag on the away lock. If there was any drag, or heavy buildup of sawdust on the back rail, it *could* be locked out of parallel.
My father has a 1953 Craftsman Table saw with a micro-adjustable fence. I have NO idea who made the saw or the fence. The fence had a knob that engaged a toothed rail and made for absolutely minute adjustments. It's still working fine, today, and has stood up to fifty years of cabinet-making.
I don't buy in to this all-Craftsman-tools-are-crap "conventional wisdom". Because, it's not true. I dislike modern Craftsman routers, because they are ungainly, unbalanced, ackward, and ugly. That said, I have TWO
20-year-old Craftsman routers (and Skill, and Bosch), that are quite adequate.James....
