Again, I applaud your efforts. I don't want to be "that" forum member who goes around playing "editor." My only intention was to be sure very key points were clear to new stringers for the safety of their frames and quality of the stringjob. No disrespect or so forth is intended.
I can give you a brief summary of what could be improvements because you asked. I'm not intending here to tell you to change your personal writing style.
1. There are some spelling errors (such as "guage" instead of "gauge" in the "calibration" section).
2. The starting method to which you link at **** seems to be a method for using fixed clamps (similar to that shown by a member, "Yulitle," in one of his videos regarding starting mains). That **** guide isn't written particularly well.
3. I'm still not sure about your explanation of starting the mains. What I see you doing is tensioning the center strings (LM1 and RM1) to set the loop against the frame and set the tension inside the clamp. You can probably explain what is happening more accurately.
4. When you talk about the weight being "balanced," I think you should note how the bar should be close to horizontal to achieve proper tension of the string being pulled. I understand what you mean, in regard to the torque to string tension, but new users might just want to be reminded to get the bar to level without pushing it down (adding tension) or holding it up (reducing tension).
5. I think you should clarify for new users that you let the bar down, as they may literally lift it and drop it. New users do all kinds of things. I don't think some bother reading the official manual. I know from forum (and life) experience that you can't say, "No one would do that."
6. In some places, you might want to rewrite some sentences with actual stringing and machine terminology or better describe the situation. For example, someone may not know what you mean by "unity tension."
7. You might want to be more clear by using terminology like, "thread the next main from head to throat, etc.," rather than (copied and pasted) "Thread a string through to the next hold and pull tension on that string." This helps focus the reader.
8. Rather than (copied and pasted) "make sure you’re skipping the right strings," you might want to be more specific and mention the term "main skip" and skipping the "holes/grommets." I only say this for clarity to someone who is a beginner, knowing precisely what to count and skip as they are reading at that point. Tell the reader why they are skipping, if only briefly. New stringers appear and ask about "main skips." They are thinking, "Mains skip what?"
9. I think most stringers would disagree with the comment (copied and pasted), "Crosses are much easier than mains to deal with."
10. I think you can make the section about tying on the crosses more precise. A new stringer may not understand, for example, what you mean simply by, "To start, thread your crosses string through the “starting crosses” hole for your racket. Then, bring the string tip around and through the “tie off crosses” hole. Yes, you thread through the “start crosses” hole and then into the “tie off crosses” hole and tie off onto the mains string that is in that hole." Some have difficulty with patterns. Some don't understand this terminology. It might be best to explain, again for example, that the first cross that is woven enters and exits a grommet of a certain number (what you call the "starting crosses hole"), such as grommet 8 at the head (left and right). This depends how the pattern is written. In your case, you are putting the string through the grommet for the first cross on the side opposite the tie off, weaving the first cross to avoid pulling the entire length of cross string, which is entering and exiting the frame at grommet "Y" (what you call the "starting crosses hole"). You are then running the string along the outside of the frame, and inserting it at grommet "X" to tie a starting knot around the anchor string. Then you pull tension on the string that you have already woven. I was just using "X" and "Y" to replace numbers in an actual pattern. They might just need those extra definitions and a map of the string travel without related photos or videos.
Again, it is just my opinion, based on my knowledge of what newbies ask and do, as long as you're going to the trouble of creating a tutorial at Google Docs.
