I'm not sure how many of you use this string jig but I would like to give it a whirl, but i need to know what is the measurement where the question mark is. I would hate to waste rolls of string to find it out so maybe one of you pros would know. Also is the measurement between the 0-9 .37?

You dont need that number. If you notice you are counting up from the bottom increasing bow length as you go. SO the peg that says 90 is for a 90 inch bow...one more inch to the right would be a 92inch bow etc etc.
If you look at the 10x.375 you'll notice the . I cant vouch for it's correctness but I can see it there where it's not on the top. It sure cant be 3.75"es between the pegs LOL!
I dont use that specific jig, I use one similar. Mine has a single post for bow length. I do want to make a new one though...idears idears. Here's a good link to a picture of one like I use..and a pretty dang good tutorial on how to build them that was posted here not so long ago, thanks who ever did it. If you're looking for a video look up doin the twist at www.recurves.com (http://www.recurves.com)

nice, i like that one it looks easy, but what if you need a different string size? wouldn't you need to make another jig, or at least re set your current one?
I also use one like in AkDan's link. And to answer your question, with a jig like that, the pin at position marked with a "C" is moveable and is numbered according to bow length, kind of like your drawing above only with one peg instead of two. So if you need a string for a 62 inch bow, you move that peg to the hole marked 62" then start wrapping you string.
That's the whole purpose of the jig really, is to have ONE compact and consistent device to measure out strings for any size bow. It also adds in "tapering" so that all strands are a slightly different length, that way you don't have a sudden change in final string diameter when you reach the end of a bundle while twisting it up.
As AkDan mentioned, I strongly recommend you getting the DVD "Doin the Twist" it walks you through everything and even includes details on how to make a jig.
Boy my jig is crude but similar to the one pictured.
Keep in mind that there will be a fudge factor with any jig especially since the tightness and number of twists enters into the equation.. So just make one and mark it up as necessary. There is a lot of string on a spool so experiment.

Ron is right, different strokes for different folks. There is no "universal" jig.
You can simply tack two nails at a specific length cut and stagger the ends for each bundle.
Some add 16" to the bow length, find a length that works for your twists!
Don't be afraid to undue a string, that doesn't' come out right and try again.Saves on material. Just keep records of the lengths that work for you! Making your own, is the best!
I've been making strings with B-50. I want to try some with 452. Will I have to change my peg positions for strings for the same bows? Will the different material result in different lengths?
I made mine of the plans on the how-to on this site, nals at the top of jig 1/2" apart, the string length pins work for a double loop string but if yo want a single loop, you have to go two length's longer
ibehiking, It will of coarse make a slight difference but hard to measure. You might have to add or subtract one twist when the string is put on the bow.

The answer to your question is 4.625" (4-5/8").
0-9 is 3.375" (3 3/8"). There are ten pins but only nine spaces.
.375" = 3/8"
Here is a link to one similar to yours, with all needed measurements, it is from the How To Section here at Tradgang: http://www.tradgang.com/stuff_bin/stringjig.jpg
remember the one I have drawn up is for AMO length, and a little trick to keep the string straight when finished, is to pretwist about 20 rev before second loop
Twist them seperatly the same way you twist the individ. bundle when you are "doin the twist"
