I have to say the CSUSA instructions are the best of the ones I make. They are getting more consistent, but sometimes they depart from their format for some kits. I agree with DW that they should all put diameters in the instructions. ONce in a while I have several bushing sets on my workbench at once, and knowing the diameters would allow me to put them back in the same parts bin correctly (I'm building a diameter table, but it'd be nice to just have it right away.)
The kits i get from both Rockler and Woodcraft have some of the most unreadable instructions (inconsistent part names, combining pen and pencil assembly instructions in the same step, no instructions on what order the bushings go on the mandrel, etc.), and I agree that some of the instruction writers need to learn how to type, and also turn a few pens...
