Broadhead tuning question

[Bowhunter1994]

All of my Broadheads are hitting high, about 3-4 inches higher than my FP's . I understand I need to move my nocking point up, but I am already sitting 1/4 inch higher than level. Is it okay to go higher than 1/4 above level?
I have never had to do that before so I am clueless and don't wanna fool with it without getting advice from someone that has done this before

As long as your bh and ft are flying good I don't see why it matters.

[Csmith52779]

What kind of bow is it?

[oktx]

Are you getting some contact with your rest?

[Bowhunter1994]

mathews z7
no contact with rest.

[DoubleGArchery]

Look at the top cam or wheel. See if the cam is leaning, if it is you may need to tighten one side of your cable. You know there are so many things that it could be, it's just a guess without starting from set up of bow. Good luck.

^^^ i wish there was a decent shop close by my area that could help me out with times like these.

Usually if something is way out of center something is out of whack. Could be numerous things. 1/8" nock high is on the upper end of too high. 1/4" is too high (to me)

1/8 is usually money on a Solo.

Correct...... But why would someone shoot a bow with that old of technology?

[Csmith52779]

^^^ that's funny!

That^^^^^^^

[Bowhunter1994]

So I called my local Mathews dealer, and they told me never to move my nocking point ( leave it at leveled, not 1/8 or 1/4 high).
Wish someone down here knew some decent info.

Level??? On a solo?!

[Low Fence]

Just out of curiosity. What arrow spine and length are you shooting as well as draw length and poundage ?

[Bowhunter1994]

Z7
69 pounds
28.5 DL
GOLDTIP PRO HUNTER 7595

[Bowhunter1994]

I've shot the same set up since 2009 and had it shooting darts with numerous bh's. But since I put new string on I haven't gotten it back to my standards

What brand string???

[Low Fence]

Arrow seems right unless excessively long. At a and brace within specs?

[muddyfuzzy]

you can ship your bow to me and i will tune it for you for 75 bucks.

Starting rotation is off causing poor vertical nock travel

Could you explain that in terms I can understand.. Lol
Starting rotation means my nocking point?

sure, let me be a little more specific.

there is a relationship between the rest, nocking point and cam starting rotation. if one of these is changed then vertical stringing can occur. when the bow was previously set up with the old string (when new) there was a starting rotation on the cam, more than likely the rest was installed with the arrow running through the berger(s) and the nock point set somewhere close to perpendicular. without making any changes to the rest we can change vertical poi by either adding or removing twists (aka retarding or advancing the cam(s)). the nock point is simply a reference as it floats on the string relative to the rest but has no relationship to the draw force curve imparted by the cams eccentrics. therefore you are essentially trying to fix bad rotation on the cam by overcoming it with the nocking point.

most bows should tune pretty close to nock level, or slightly high ( 1/8"). this means that the starting rotation is pretty close to optimal, with the best way to tell is by running the bow through a chrono as most bows will make optimal speed this way. of course, this can be magnified by broadheads like most tuning problems but may not be evident shooting field tips.

Thank you sir, I am a little picky about my bow. Good info bud thanks

[muddyfuzzy]

your cam should have a timing hole, how does the cable pass through the hole? centered is the starting point.

[Bowhunter1994]

Yes that is centered ^^^

[muddyfuzzy]

is your bow maxed out or turned down?

[Bowhunter1994]

Turned down a bit.

[sambo73]

Good thread and info

[muddyfuzzy]

the starting rotation is set with the bow @ peak weight (maxed out). The cable should pass through the hole at this time; however, when the limbs are backed out the orientation will change. if it is in the center of the hole with the bow backed out then the starting rotation probably needs a little work.

if it was my bow i would do the following:
1. max the bow out
2. set the starting rotation on the cam
3. set the draw length
4. make sure the bow is hitting peak weight and full let-off
5. set the idler for zero lean @ full draw
6. reset the rest to make sure the arrow is running through the berger(s) on the riser
7. set the nocking point level to 1/16" high
8. begin the tuning process again

There is no way in hell that I'd pay anybody $75 to tune a single cam bow unless I had to pay for a new rest or strings.
Whoever put the strings on, incorrectly twisted the strings, or the strings were the wrong length to begin with, or , heaven forbid, the stretched a lot.
If your cable is centered in the hole, with the bow backed off, your cam rotation is wrong.
Not $75 wrong, but wrong.

classy as always rocky.

it costs me 40.00 bucks to ship the bow back, you really are a piece of work. thanks for rolling up in here and taking the words right out of my mouth(literally) and acting like you know what's going on.

op, i'm out....... hope you get your issue resolved.

rocky, it sure was nice without you posting for a while, or at least that's the way it seemed. wishing you all the best....

This was your post.
You didn't say that your cost for shipping was $40 .
You simply said that you would tune the man's bow for $75.
I don't grasp your issue with me.
AS a matter of fact, I do know what's going on.

don't forget I TOLD him what was wrong with the bow, then your boy rocky rolls up in here with you snapping at his heels, well we all know what happens next.

you think that's funny, you're an enabler.

Uhhhh. You took that totally wrong dude. And I know plenty. You know that. But I didn't need to add much cuz you covered it right off the bat.

Nice blast at me btw. Sorry I like to laugh.

[Bowhunter1994]

Settle down fellas ... Thanks muddy fuzzy you helped a lot.
Rocky I don't know you but he was helping me and you bash him for a offer he gave ME. I knew how much it was to send a bow and I automatically deducted that from the 70$. I haven't jumped on it because I want to see if the problem can be fixed locally without having to ship.
I found someone down here and hopefully issue gets resolved SOON.

Don't forget that there's one or two guys at Point Blank that should be able to fix you up. Beto is the tuning guru there so ask for him. Let's shoot when you get her all tuned up.

There was no intent to bash ol' muddyfuzzy in my post.
His advice was correct, and I didn't say anything to contradict it.
All I said ( advice from me to you), was that $ 75 is pretty steep to tune a single cam bow, that obviously has a simple cam rotation issue (over advanced) due to improper installation of strings, or improper length strings.
Again, there was no mention of shipping in the $75 quote, only that he would tune your bow for that amount.
Maybe I should have just simply known that $40 was for shipping
I own an archery shop and tune lots of bows of all makes and models.
I don't have a clue what muddyfuzzy does for a living, but I do know he gets on here to help and gives lots of advice.

This is good advice for me.

He always does. Muddy knows his stuff.

[cvansickler]

Not a tuning guru, would lowering your rest help. i.e. 1/64" or so
