My bow is about exactly 75" from nock to nock. My bow string is exactly 72" from nock to nock. The bow is a straight profile english longbow. When I string the bow, with the string that is exactly 3" shorter than the bow, the brace height is like 10". I am stumped. The only thing I can think of is because the bow has about 2" reflex in it, the back stretches out when bent and strung essentially making a longer bow, equally a shorter brace height. I have no clue. The string is a fast flight endless loop string, I haven't put any twist in it yet. :o
Either way I am off to go make my third string, this time about an inch shorter,... ;D
-
Make it longer and twist It down

Lol! That's funny! Sort of like "I cut it off three times and its still too short!" Josh

I do stuff like that all the time, you are screwing up somewhere on your measurement LOL. Arithmetic don't lie!

Well if u make it shorted your brace will get bigger

Toomany knows that, man. That last bit was meant as a joke. Josh

LOL, :). I swear though, I measured probably at least 25 times in a row, no idea. I just made a 73" string and gave it a couple twists.
-
I think that 2" of reflex doubles to make 4" and 3" short should make up for a total of 7" if that makes any sense. And maybe add another 3" for the circumference difference. .......lol......... ??? just guessing
-
I measure the length of the actual wood, I think you did that also? Didn't you?
-
Cut your string strands 10" longer than the t/t bow length, twist an eye in one end and make a bowyers knot in the other end. If it is too long or too short just retie the bowyers knot to the correct length. ;)
-
Yeah, that gave me a good laugh ;D...
I'm sure we've all done it tho' not everyone will admit to it.

Try a flemish twist double looper....what a pain ;)

I may have been doing this wrong, I measure the bow on the belly side from nock to nock and make a string 3" shorter, not the air distance between the nocks when dealing with reflex..

You make a Dacron string 3" shorter because it'll stretch down 1". FF won't stretch so it'll only be 2" shorter..........Art

TMK...Funny you bring this up. Earlier this summer I had a few bow making friends over for a few days. Sat down in the living room on a rainy afternoon to make a string for a bow I had just finished....4 tries and four strings later I got one to work. My friends laughed louder each time the latest string was too short by the same length as the one I just finished cussin'. Still cant figure out why that particular spool of FastFlite had such shrinkage issues.

Glad I'm not the only one! :o

Welp, just to update yall, everything is measuring the same, braced or unbraced. ;D Bow is 75" ntn, string is 72 3/4" from end to end. So the string is 2 1/4" shorter. Brace height is about 5 3/4" or so. The string measures the same length braced or unbraced. I was thinking maybe due to it's positive tiller, it may make it seem a bit higher than normal, I don't know.

I've never heard this before anywhere else, I make my flemish ff stings 3" shorter, but that is before they stretch out, right after I twist them up.

Yup.

Toomany,
What are you using for your String Jig?
I had a similar problem with Endless Loop Strings before I switched to Reverse Twist strings.
It turned out my String Jig was bowing there by making my strings come up an inch or so short.
It happened most with longer strings...

Yup.
So, once your string settles in, and you have to give it a few twist to maintain brace height, that it'll be 'bout 2" shorter than the bow? ;) ;D

lol :) I think every bowyer becomes a great string maker................I make 3 strings to every bow I make. The good thing about that is after 10 -12 bows you might have a string for the next bow you build :laugh: :laugh: :laugh:

I always measure the string im tillering with while the bow is strung at proper brace to get get the lengh.
-
The string I tiller with is the string I use. I make it long to start with then shorten it as the bow is ready. By time I am down to brace, the string is already all stretched out and ready to go too. No worries :)

Smart idea, I will do that next time.

Heck no, not me! That's out of my pay grade. I tried it a few times and I ain't got it. One loop and a bowyer's knot for me; that way I can always make it way too long the first time. I know it's wasteful, but I am not a math guy, so it keeps me from making a half a dozen strings that won't fit my bow. :)
