Welcome to Knock-On Podcast where we bring you archery information and education that you can trust.

Knock-On was created as a way to bring all archers together regardless of the brand you choose or the style of archery you shoot.

Knock-On Podcasting will deliver professional insights to the latest gear, proper shooting technique along with high-level equipment setup and tuning.

Hey hey hey everybody let's roll or welcome back to another Knock-On Podcast regardless of which intro you like I'll give you both.

So that's what you got but yeah we're here on a Sunday morning and I'm gonna do what I promise I'm gonna keep plugging away with these questions that you all sent in.

I had a pretty good two-hour podcast the other day but starting to get caught up and I am going to work my way through more of these questions from all of you out there.

I appreciate everyone being patient with me as I had a little bit of time to myself.

But first question here is gonna be from Eric Faye. He's asking does adding more weight to the rear of the arrow, i.e. lighted knocks and fletchings help to stiffen the spine or does it continue to break it down.

So anytime you add weight to either side of the shaft you're technically breaking it down. You're you know you just kind of think of it like any type of long handle that you have the more weight you put on the end of it the more that that's gonna bend.

And that happens regardless of which end of the arrow that you do that with. So lighted knocks, super heavy fletchings, different types of bushing systems that they have on the back of the arrows, sleeves, some arrows take sleeves on the back.

I've seen I think there was a company called new fletch that had like an aluminum piece that went on the back of the arrow where you could unscrew the knock and just slide your veins in so you didn't have to learn to fletch your own arrows.

But also adds a ton of weight and really reduces your FOC. So not really a great idea when it comes to practicality.

So yeah another thing too is vinyl. So vinyl wraps can also stiffen the arrow too if you know you're wrapping that on there because the weight of the vinyl is fairly light but you're actually adding something that's you know that's a little bit stiffer around the outside edge of that shaft.

So it's kind of a fine line there. Certain points for example go further up inside of the shaft. So the further that that point is inside of that shaft the mortals stiffen the arrows so to speak.

That's kind of a loaded response because obviously adding weight to the end of that arrow will weaken it. However the longer you slide a solid object inside of that shaft then technically your bending points are shorter so it's harder to get that.

So in other words if you have an arrow and you put a hundred grains on the front and a 50 grain you know fletching set up a knock on the back if that arrow is 29 inches long it'll have a certain type of spine rating or flexibility.

But if you take that exact same arrow and then cut it down to where that's only 26 inches long with those same builds that arrows actually stiffer and that's spine or you know how flexible that arrow is is stiffer so that's why for example on some of my target arrows like for example on my pro fields which is a target arrow that I have the pro fields I can actually use in the field.

And actually use an ACE insert which is a tubed insert that slides way up inside of that shaft and then you screw on little small bulge points on the end and the reason I like that is because on for me personally on my target setups.

I'm kind of right in between a 410 or 420 spine and a 380 spine so what that allows me to do is that allows me to use that longer shank that goes up inside of the front of the arrow and because it's longer it stiffens that arrow just enough to where I can get away with that 420 shaft.

The other thing you've heard me talk about probably in the past as well is that for example on an X 10 arrow or a pro tour you have the option of either using a tungsten point or a stainless steel point the stainless steel points are much longer because the material itself has to be more to equal the same mass.

So a stainless steel point which are actually cheaper in like say 110 grains that could probably be almost 3 inches long versus a tungsten you would break off one little chunk and you would get it 110 grains and on that tungsten it's probably only about 1 1 1 2 1 2 1 1.

So technically even though the weight's the same you've got almost an inch and a half less of that arrow that's actually flexing as it comes out of the bow so you can get different response that way but what you really want to do is try to be smart about the amount of weight that you put on the tail end of the arrow.
