Gents,
Just got in my Easton Traditional 400s in and started tuning them today. I left them full length with 75grain inserts and 175 head. After getting my knock point set my bareshaft and fletched arrow are impacting together, but the bareshaft its pretty knock high. Any opinions on this or would most call this good and rely on the fletchings to flatten it out? Left and right so far are good. The 200 grain point flys well too. Shooting a Bear Montana 28@50. Thanks
How high do you have your nock set off the shelf?
Currently set at 9/16.
How is the bow tillered?
How do broadheads and field tips impact?
Not exactly sure on the tiller, but a quick search yielded the top limb about 1/4" longer. I am new to tuning longbows and have not bought the broadheads I want. Wanted to tune with field points and decide on a weight head then continue the process, so I cannot answer the second.
You're shooting a pretty skinny shaft. With a 9/16 nock point height, your arrows may be coming off the bow nock high. Might be able to lower your nock point a little to straighten them out.
Lowered it all the way down to 1/4" and the arrow is still in the target knock high. It came down a little but not enough for the adjustments I was making. Anything form related I can focus that causes knock high flight or anyone else have any suggestions on the culprit? Thanks
Form related, vertical bow or string torque could throw the arrow nock high. If you grip the bow fairly loosely, bow torque shouldn't be an issue. If you grip it tight, with too much pressure on the throat or heel, you might be torquing it vertically. If that's the case, loosen up a bit and see if that helps.
Vertical string torque can be caused by out-of-proportion pressure on the string by the various fingers, usually too much or too little on the part of the index finger, if you're a split finger shooter. Try to be aware of your finger pressure and try to equalize it somewhat. The ring finger usually doesn't apply as much pressure as the two above it.
A high drawing arm elbow will put downward pressure on your index finger and can also cause the arrow to come out nock high. If you have a high elbow, might try lowering it a bit.
If you're using only one nocking point, the arrow could be slipping on the string. Try two, one above and one below the nock, if you're not already
All this being said, it seems like you're pretty close as is. If none of these things remedies the problem, just fletch them up and shoot. Good luck.
Well I went back up some and installed a bottom knock tie in and found the flight I was looking for. Nice and straight now, I like to think luck had to play a role, but I am ok with that. Top knock is at 5/8 and bottom at 7/16. Straightening out nice. Currently fletching them all now and will probably be shooting a Grizzly or Cutthroat singe bevel. Thanks for all of the help. Gained some confidence doing this.
