I have 9 platinum plus 1916 arrows, 100 grain points, 3x4 feathers, weight 465, same foc. using a SK at 40# with 271/2 draw. The arrows are straight. Eight fly perfect, one does a loop when shot. The fletching is 1 inch from end of arrow, straight fletch, 1 degree offset. The fletching is identical. I can not see any thing different about the arrow. I can't figure why the arrow loops.

Pull the point and shine a light down the I.D. of the shaft.

Now?...see that line on the I.D. wall?....that's...

"The Weld Seam"

and it's probably not clocked to the same radial position as your other 8 arrows.

Is your nock too tight on the string?

the nock is the same as the other arrows, thanks for the suggestion.

Maybe the nock is not on perfectly straight?

Is the nock crooked, or bent? Does the arrow have a small but long bend in it? Put it on a straight edge and roll it to see.

X3 the nock or really check to see if a little bit of fletching came unglued

checked the nock, appears ok. did a roll test arrow is straight. thanks

try a different point?

Well, there's something there. Perhaps Jinkster is on to something. I've never heard of that, which means essentially nothing if it is a thing.

I would change the nock, and try it, and then change the point and try it if that didn't work.

Where are the other three arrows from a dozen?

Box Call:

"How should the weld seam be lined up with the nock and cock feather?"

There is no right or wrong way there as the weld seam can be positioned anywhere however?..."Uniformity"...of where it's located should be common among all arrows.

Easton "X7" shafting was the first shafting to do away with the weld seam by offering up "Extruded" (re: "seamless") aluminum shafting and back in the day were the only shafting that archers who rolled their own didn't have to concern themselves with locating the seam and making sure it was positioned with commonality prior too fletching them up.

I have them as bear shaft. The weld seam I will check, could this be enough to make the arrow loop?

Idaho: It's towards the top of the "Possibilities" list.

Reset the nock 90degs and see what happens.

Other possibilities could be a poorly aligned nock or simply a bad shaft.

The shaft is "female" and will never be serviceable, discard it and move on. You have already wasted more time and effort than it deserves.

I was just trying to possibly find more clues with your MYSTERY arrow. Perhaps one or more of the three arrows missing held more clues. Replace or weigh the point to confirm that point indeed weighs the same as the other eight. Did you build these arrows? Mark

I build my arrows, been doing for 50 years. The reason I posted the thread was I have never seen an arrow loop like this. I seen fish tales, etc. but this actually make a loop at 30 yards. I had a friend watch and confirm the loop. The arrow appears to be the same as all the rest. I am not trying to save the arrow, I just can't figure out why. I will change the point later today to see if that makes a difference. thanks

If you fletched them your self, did you by chance happen to use say, 2 right wing and 1 left wing feather ? I have seen this happen to a friend of mine and that is what his arrow did, "The loop De Loop".

What exactly is it doing that you call "looping." Is the nock end making a circle around the line of flight?

Jim, you may have solved the problem. I use only right wing feathers but a left wing may have been in an right wing order. Later today I will check the feathers to see if they are left or right. What you describe is exactly what the arrow does. thanks

Jim, to answer the last question, the whole arrow does a loop on the way to the target. thanks

Weld seam on an Easton,aluminum arrow?Are you sure about that,Jinkster?I thought they were extruded and seamless?

I would suspect the nock.I would change it and see.All nocks aren't made perfectly straight.

There maybe one other option if it is not the feathers. I have done this and not realized it, nock orientation. Thought I had the fletcher in the correct timing when I started fletching the shaft and it wasn't. Just a thought. DANNY

Whatever it is a close visual inspection should reveal the cause.

Easton aluminum arrows are all extruded nowadays and have been for awhile. The start with a thick long tube and pull through a die (extrude) to get the diameter they want.

I say you've got a bend somewhere towards the fletching...

Jim B:

"Weld seam on an Easton,aluminum arrow?Are you sure about that,Jinkster?I thought they were extruded and seamless?"

Well Jim?...Until you questioned me I thought I was sure because back in 1987 I use3d to pay a pretty penny for my 2114 X7's and mainly because they were the only extruded/drawn tubing alum. shafts Easton sold besides the barrel cores for their ACC line of arrows and all others were welded seam tubing then again?...I haven't dealt with any of Easton's alum. shafting since 1994 so I figured my thoughts and info could be a bit dated so what I did was I called Easton Customer Support (SLC, Utah) and asked if the Platinum Plus line of arrows was seamless or not and he was honest enough to admit he wasn't sure but took my number and got back too me (after the engineers got out of their meeting) and the answer I got was...

"All of their aluminum arrows except for X7 Eclipse are welded seam however they go through process whereby the I.D. seam is conditioned too a point that it has no effect on spine regardless of position and can not be seen by the naked eye."

The young man's name was "Zack" and he was just the messenger.

GDS: I'm pretty sure no one is going to be purchasing "Extruded/Drawn Tubing" arrow shafts at L.A.S.'s $4.42 ea.

X7 Eclipse shafting is $8.50 ea and as far as I'm concerned?...that a great deal on the most awesome alum. arrow planet earth has ever seen.

"The Tip Off" (of the manufacturing process) is in the way Easton specs their weight tolerance (by % not +/-grs) and extremely high strength...

• Weight tolerance: ± .75%

• Strength (psi) 105,000

But at this point?...I conceed that Idahodick's looping issue is NOT weld seam/spine related.

I've seen arrow flight like this a league night shoots. A point or nock would get pulled when the owner didn't notice and a little bit of water placed in the shaft and sealed again. The owner would get so frustrated with that arrow they would break it.

I think raghorn just solved the mystery. {I checked the feathers and all were right wing}, I had left the shaft outside and during the night we got a light rain. So some water got into the shaft and I sealed it up. I think I will leave it as is, It makes an interesting arrow. Thanks to all for the advice.
