Hey guys we're continuing our arrow build and what we're gonna do is we're
gonna index our arrow. So before we fletch we want to know
which way the arrow wants to naturally spin coming off the bow. Since we're
building our own arrows we're gonna fletch using helical or offset. One or
both the offset helical. What that does is it induces spin in the arrow through
your fletching. So if you buy a factory fletched
arrow such as this one, kind of the industry standard is a one degree offset.
And what that means is is you look down from the nock end of the arrow you're
gonna see the front end of the fletching is gonna vary slightly sit to the right
of the back end. That's a one degree right offset and that will induce some
spin in your arrow and that's fine if your arrow naturally wants to spin to
the right. But if your arrow wants to spin to the left that's not going to be as
good for you. So what we've seen in high speed videos
is the arrow spinning as it comes off the bow. If you're fletching doesn't
match the natural spin. What we've seen is the arrow will come off it'll start
its natural spin and then as it gets downrange the fletching will take over
and it'll spin back the other way. Well that's wasted energy on the part of
the arrow we want it to keep spinning the way it wants to go. And what that has
to do is not whether you're left-handed. There was an old adage that if you're a
right-handed archer you wanted to shoot a right helical arrow. Left-handed
archer left helical arrow. That doesn't matter. What it has to do with is the
direction that your string is twisted and therefore the serving that dictates
which way your arrow is going to spin. But there's a simple test don't bother
looking at your string there's a simple test to figure out which way your arrow
wants to spin. So we have here our Black Eagle Rampage 300.
that we are building. We got a silver sharpie here and so all I'm gonna
do is on the very top of this arrow I'm gonna draw a silver line straight down.
You can see it's right in line with the nock. So I'm gonna shoot here. I'm
shooting from a close distance. I'm only about I don't know eight feet away from
the target. I'm gonna have my silver line facing directly up and also I'm going to
do is shoot into the target and then go see which way the arrow is spinning so
it's just going to look like this.
Okay so now you can see that my nock and my silver line have turned to the left.
That tells me that my arrow naturally wants to spin counterclockwise which
goes to the point that it doesn't matter what hand you shoot because I'm a
right-handed shooter and this arrow wants to spin to the left. So just do
this simple test and you can figure out which way your arrow wants to spin now.
Why that's important is when I go to put my fletchings on this arrow, I
know that I want to put them on in a fashion that promotes a counterclockwise
spin and then my arrow is going to be doing what it naturally wants to do.
