String not on center?

Hello,

Rookie question here but here it goes.

When I shoot my bivouac backland long bow, the top string and limb don’t line up, I can sort of push it back over.

Why is it doing this? Is it a problem? These limbs don’t have grooves in them like my other bow does. Here’s a pic I took right after shooting 5 minutes ago.

If you put a half twist in the string on that end does it do the same? It's likely the string groove, but it could be the lay of the string too.
 
What does the lay look like on the lower limb? Centered ??

This is an ILF limb model?

If so I would check the fit of the upper limb in the (pocket/bracket) this could happen if your top limb is canted a bit to the right.

Is is an ilf bow, I’m going to mess with the string, I’ll check that limb thing out but I don’t think that’s the case.

Bottom string is centered.
 
Curious what your brace is at? Looks like the string is laying on the limb? Longbow strings shouldn't touch the limbs, if it is laying on the limb like a recurve, then that could be your issue.
 
I would check your limbs to see if they are twisted - it can happen for a variety of reasons. Usually an easy fix.

This is interesting. I’ll measure the brace height and check to see if it’s the same as they wrote on the card when I got it.

I got on some websites to look at bows and like you said, even the reflex/reflex models don’t have the string touching the limb, even on bivouacs website, their picture shows the string not touching the limb.

Ok found the card, the guys at bivouac said it should be 9”, based on that and the photo, what do you think?

I had the bow unstrung but with the string loosely on it I wonder if I somehow managed to loosen it.

Ok, the way I was taught is to turn the square around from how you have it and place it in the deepest part of the grip and measure back to the string. Long bows, especially decent quality ones will never twist the limbs, but what will happen with RD longbows, is when your brace gets too low, the limb will kind of collapse back the other way in the middle and usually it only happens on one end and it will make your string lay down on the limb. My Dryad used to do it all the time, didn't have as good of strings then and they crepped more.

Thanks for the reply, a lot going on here and I’m learning a bunch. As I’ve mentioned in most of my trad bow threads, I can shoot the things ok but I generally have no idea what I’m doing.

Here’s my thoughts. I assumed when I got the bow that it was all set up with the string and all that. Im guessing they just gave me the 60” string and the brace height number of 9” figuring that anybody spending that sort of $$$ must know what they were doing.

I just threw the string on and went and shot it, it seemed ok but what do I know. When I measured the brace height the way the videos show, I was getting like 5-3/4” and lots of string on the limb. For the past half hour or so, I’ve been twisting the heck out of that string and I’m over 8” but going to keep going for the 9” they recommend.

The string is no longer touching the limb and it is getting noticeable harder to string/unstring. I’ve also been walking out and taking a few shots after each adjustment and the thing is noticeable more quiet.

The string still isn’t centered though and it’s bring out my inner OCD which I hate. Now it makes sense though why longbows don’t have string grooves….because the string shouldn’t be on the limb.

My black widow recurve is sitting at 9” again, without me doing anything, just putting the string on it, getting my nock to 5/8ths and shooting.

Anyways I’m going to keep working towards that 9” brace height, maybe like 10 more full twists on the top loop and I’ll report back.

Whoa, that bh was way out of spec. It'll be like shooting a different bow once in spec. Once you get it in spec, measure from the ends of the loops so next string change you can get it in the ballpark straight away

Yeah, I’m sure the guys at bivouac knew the numbers off hand and assumed I’d know how to set it up lol. Very different bow now.
