Artwork: How pulleys work#2: With two wheels, it's as though the weight is hanging from two ropes (the two strands of the same rope on the left), and a pulley halves the lifting force you need. It's like lifting the weight with two ropes instead of one. But you now have to pul...
So how do you use it? The basic idea is simple: you press a key (1) and a lever attached to it (2) swings another lever called a type hammer (3) up toward the paper. The type hammer has the slug of metal type on the end of it. Just as the type is about to hit the page...

And once you are guiding, you are limited by centroid accuracy and response and - well - you are guiding anyway - so what is the benefit of encoders vs. tight guiding. It may mean "less work" for the guider - but who cares how much the guider works if the resulting fwhm is small...
