Arrow Setup Question.

[Gerald S]

I have been bow hunting for 20 years but, I have never paid much attention to what the pro shop guys were doing when setting me up. Add to that, I rarely change what I'm doing. The most I do to my own setup is fletch my own arrows and change my site or rest. However, I just ordered new arrows and I'm thinking about adding some length to them. Currently, with some broad heads, they won't clear the riser. Adding and inch or so would solve this problem because it would get the head out in front of the riser.

So, would adding an inch to the arrow change anything else that I would need to be mindful of?

My set up in case it matters:
Mathews Outback
27.5" draw
26" arrows measured from nock (currently)
67#'s
Axis 400's

wouldnt it just add weight?

[rocky]

Adding 1 inch to the shaft will weaken the spine as well as increase weight.
I think something is out of whack if you have Bhead clearance issues.

[DaveC]

I would think the 400's would still spine OK for your set-up.

If you have a cut saw available just cut 3 to the length you want and see what happens.
If you like what you see do the rest, if not- go back to what you know worked,
OR figure out why your rest is set up so close to the riser to cause BH clearance issues. (Assuming it was a side clearance and not arrow shelf clearance issue. )

Finatic...

Adding one inch to your arrow length will not do anything but add a little more weight to your arrow. If you are shooting correctly spined arrows for your draw wt, then you should be fine. Arrows are made and spined for 28 inch draws...

The 400's should be fine shooting at 67 lbs draw weight, no matter if they are 26 inches in length or 28 inches in length. Just a little heavier with an added inch. You may have to make a minor adjustment to your sights though to make up for the extra arrow wt. You should gain a little kinetic energy as well.

By the way...do you use that avatar on the ATVFrontier Yamaha forum?

I agree with DaveC.-If you are hitting the shelf , raise the rest so that the arrow is even with the rest mount hole in riser. If the arrow is hitting the side of the riser, center shot is too far inside. If you are shooting a drop-away, center shot should be ABOUT 5/8 inch from riser, but if you are shooting a conventional rest,centershot should be about 3/4 inch from riser. IF you have a cam that is leaning, youwill have to set centershot further inside to tune the bow, and I suspect that this might be the case. I personally never manipulate centershot to accomodate a leaning cam, GET IT FIXED at your local Mathews dealer. Also, I don't like to manipulate centershot to accomodate a particular rest or a shooter that pulls the string to the left. These are all common problems that would cause centershot to be (inside) and should be addressed at the cause. I'm assuming you are right handed.

Knight- arrow spine deflection is measured at 28 inches

[Chris]

Why is the centershot on conventional rests and drop-away rests different?

[rocky]

Cables being on one side of the bow causes torque. With a conventional rest, you get a little side support that you don't get with a drop-away. Because of this torque, centershot is rarely dead-center, it is usually slightly inside with a conventional rest and a little more with a drop-away. READ "USALLY".

[rocky]

Bad spelling- READ " USUALLY"

[Gerald S]

Thanks for the info so far. Let me give another detail and ask the question a little differently.

I have about a 1/4" of clearance from my riser, not the shelf, with my Slick Trick 125 magnums.

Let's say I want to shoot the Gobbler Guillotine. To do so, I am going to need an extra inch added to my arrow. Will this effect my arrow flight other than the extra weight?

Edit: I am shooting with a drop away.

[Knight in Mossy Oak]

The answer is "no"...other than the wt issue and maybe some planing issues shooting the guillotine.

I bet you have a Yamaha...don't you?

[rocky]

Most likely no. It depends on how close spine is now. If you are borderline now, the extra length could put you under. I'm a big fan of shooting "stiff" arrows because I rarely encounter problems as long as the bow has fairly level nock travel.

[rocky]

Remember, adding weight to the front of the shaft weakens spine and decreasing weight stiffens spine so if the GG weighs less than your ST's it would Most likely have no effect.

[jmoore]

It should not, but for the Guillotines I would reccomend also full helical fletching and turning the bow down for the best flight. I use different arrows for guillotines than broadheads and have both in my quiver in the spring with my bow is set at 52#.
