Question by ALJoe. Uploaded on November 01, 2010
I shoot a three blade Thunderhead and if my nock, fletchings and blades are not lined up properly, when I draw back, a blade scrapes the side of the bow. So in this case, it is very important.
Mine don't always line up and it doesn't seem to affect accuracy. The nock and fletchings are more important so the fletchings don't hit the rest.
I did that years ago before the lower profile and more aerodynamic broad-heads available today.
I shoot Montec on carbon arrows with Blazer vanes.
I have no problems with flight.
As for Expendable, I have no experience with it, but they say they should shoot like a field point.
I personally could not get the 4 bladed to shoot as could as the 3 and I tried everything.
Lining up a blade to fletching is overkill but lining up the broadhead to the shaft is fairly important.
I test each head after screwing it into the shaft to make sure it is screwed in straight. I place the shaft of the arrow into a groved box with the point of the broadhead against a wall. As I spin the shaft the point should come to rest in the same hole each time. Often it does not. I will then unscrew the broadhead and screw it back into the shaft to see if it is straight again. This test exposes bent broadheads, crooked inserts or poor seating of the broadhead.
I can't say I've ever taken the time to line my broadhead blades up with my fletchings, but the arrow is spinning so lining them up doesn't mean the blades and the fletchings are going to cut through the same path anyway (unless your arrow speed is perfect, you can do the math). All I know is field tips shoot better than fixed blade broadheads, but the difference in accuracy is small enough I'm still confident with a broadhead. If you want to line them up I don't think it will hurt but I don't think it will help either. Like I said I never took the time, maybe I'm wrong.
I screw on Rage 2 blades and they shoot like field points. Do use one of those tools that make the face of the insert square with the shaft. Forget what it is called and who made it. Might have been G-5
I dont worry with my Montecs lining up, they fly great and just as good as my retired Spitfires!
never went through all the effort of that and have never had any trouble myself but had wondered if it made a differance. but my groups are close enough I stopped worrying about it
the blades don't need to be aligned with the flechings but make sure they are spining true with and balanced to the shaft. also the proper weight.
Used the Muzzy MX-4's and had great sucess. With modern vanes, arrows, and broadheads, its a myth of the past.
