Bow issue... Can't figure it out.

[WStreblo]

Having an issue with the bow here. Was having some erratic arrow flight and the speed just dropped. Couldn't figure out what was going on... After looking it over it was a mess. Cam lean was bad, string stretched, timing was off, axle to axle and brace height was out of specs... Got all that back to perfect and speed sky rocketed up big time. 310fps (gained 24fps from before bow tuning) however, shooting here at the house where I could really really focus on the arrow flight I noticed they are still corkscrewing or fishtailing down range only not on every shot. I can't figure it out.... Anyone???

Start with the obvious man....it is a Hoyt right?...j/k

If the nocking point is incorrect the arrow will porpoise on the way to the target. If the center shot is not correct the arrow will fishtail. If both of them are incorrect, the arrow will corkscrew.

I'd take it to a pro shop myself

is this the new one out of the box you got from me?? i didn't do anything with it at all but I could've checked it if you wanted. Hoyts are pretty good with nock travel so between level and 1/16" high should get you close and then center shot is what it is. you can work with cam lean but they must be timed and that's after you put your accessories in your string. I'd say your bow is slightly out of tune. when you shoot with not as good form as the last shot, that will exaggerate the corkscrew. Another thing is Hoyts have a stiff riser with that bridge so your center shot should be close if you eyeball it right. I use paper tuning for nock height, getting a bullet hole at 5, 15, and 30 feet. then I walk back or French tune to get center shot depending if I'm inside or can get outside or some more distance.

if ya can't get it or don't have a press you're pretty much stuck taking it to a shop. just make sure they don't put the nock square, eyeball the center shot, and then say it's good. lol

Thanks for the input fellas, once I get home from this road trip I will see what I can find out and let y'all know. DbHunterNY it's the vector I got from you last year. It was shooting great then one day I could tell something wasn't kosher. Thought I was doing something with my form but realize now the bow itself worked out of time and tune. I did call the pro shop and their first call was a new string is needed based on how much I shoot... If that's all that was needed I'd do it but I think there's still more to it.

limbs are pretty good but if there's a problem with them then they should be under warranty if you filled all that stuff out. to have the cams be suddenly out of time I'm thinking some strands within the string may have broke. that'd do what you said happened so I agree with the shops initial assumption. keep us posted. hope you get it straightened out. my cousin and his friend I think are coming tonight to have me tune up their bows. I never know what I'm going to see with my family bringing me bows. lol

They put a few twists in the string to get everything to specs... Within 30 shots it was back out of time. New string is being made and should be back to shooting by the weekend. Good luck on the bow work Dan

sounds like it's just worn out. a new set of premium strings should get you back out there for a couple years with you shooting a lot.

they showed up one had an old string on his Hoyt Alphamax but it was still in working order. rest and nock point was way off kicking nock high and just messed up. got it paper tuned in a few shots shooting a perfect bullet hole. the draw length was a little long for him and he was doing some other stuff you're not supposed to. did a little coaching and measured draw length. he's got to go to a shop/dealer to get modules for correct draw length as I don't have them. my cousin had bigger issues his Diamond bow as the serving was worn at the cam module and the bare string was wrapping around it. it's stock string and cheap to begin with. it's only the cable so I told him he has to go to the shop and order a new cable.

I can do a lot at my home bow shop and have lots of points, string accessories, and other stuff. However, stocking strings and modules is where I draw the line! lol I will say hoyts do tune well.

The corkscrewing could be a misaligned insert. I knocked two of them off last fall and it caused the corkscrew on those arrows.

To test this you need to spins the arrow on the point in the palm of your hand. Grab it between your middle finger and thumb and spin it on that same palm. It takes practice but really works. If the insert is correct you won't feel a vibration. If it's wrong you will feel the arrow wobble. You can't see it but you can feel it on your hand.
