Broadhead tuning
 

how does this chart work??? if i move the rest won't it move my practice heads aswell???

RE: Broadhead tuning
 

Yes, it will move where your field points are hitting. The idea is to have broadheads and fieldpoints group at the same point of impact. Once you achieve that, then move the sights, not before.

RE: Broadhead tuning
 

That's exactly correct. It sometimes is just not possible however to get both heads shooting to the same point of aim. You have to have everything setup properly. I have a link you can check out that will help you to see if your on the right track. http://www.broadheadtests.com/TUNING.html

Paper tune the bow first, that may solve the problem.

RE: Broadhead tuning
 

sorry guys but this chart did not work at all...i am so mad right now...all this chart did was make me loose 3 more arrows....im a lefty....my broadhead was going left about 8 inches and the hight was perfict..so according to the chart i move the rest right....right???...all it did was move the practice head like i stated and i'd move my sight untill everything was as far right as possible and the broadhead was still going left of my practice head...any thoughts would be greatly needed....thanks

RE: Broadhead tuning
 

Did you read through my link? you have to paper tune before you do anything. After that you mus understand that anyting you do will change the impact point of your arrows in relation to your sight's. Therefore after paper tuning you need to shoot at very close range at first to get your pins set so your on target, then move back to longer ranges and see how you heads hit. At that point you make very very minor adjustments. You also need to have good arrows, spined correctly with enough helical or ofset on the vanes or feathers to control the arrow.

RE: Broadhead tuning
 

You do? I never knew that and have tuned a bunch of setups. I find bareshaft tuning much more sensitive and easier to tune than the paper. And then aftewards, I see good tears in the paper anyway and usually if done right BH's hit where fields do.

But I have seen a whole bunch of people paper tune and then shoot BH's and have to make a bunch of adjustments.

RE: Broadhead tuning
 

whats the diffrence between the two??? and how do i make a paper tunning bord thing???...i don't have an archery shop

RE: Broadhead tuning
 

Broadhead tuning and paper tuning are 2 different things and will have 2 different results .

I like to hunt , and shoot fixed broadheads , broadhead tuning is the litmus test for me , paper tuning a waist of time , havent done it since I learned it was a useless exersise .


Broadhead tuning ,

If, you , your bow , and your arrow are close to being tuned when you move your rest slightly left to right , your field tipped arrow will move slighlty on the target but the broadhead tipped arrow "of the same weight" will move in the same direction but a futher distance , say at twenty yards the field point arrow moves 2 inches , the broadhead tipped arrow "should" move 4 inches in the same direction . Same for vertical movement .If your bow is not tuned well , If you are over bowed , if your arrows dont spine match your bows power very closely or are too weak of a spine , and your form is not consistant , good grip , consistant , and so on , broadhead tuneing will give you fitts .

RE: Broadhead tuning
 

yeah ijimmyit got me many fitts alright...i don't think its a consistant problim b/c normaly when im shoot practice tips i have to shoot 3 diffrent dots for 3 arrows or i'll robbin hood everytime...so last night...i tryed the chart...and i shot at the same target..so i shot about 1 inch group with 3 practice arrows and same with braodheads i was slicing off fletching almost every shot....it wasfunnyonce i moved everything to the right i started to move everything back to the left it seemed like it was getting closer then i ran out of sunlight....im going to shoot again tonight and and try moving everything to the left???

RE: Broadhead tuning
 

I'm a lefty like you. After getting myself hopelessly confused with articles about this and that, I asked a guy (who was also a lefty) about tuning. Basically, you have to take everything you read about tuning and reverse it. If you have photoshop or paintshop (heck Windows Paint might even work) take your chart above that you cut 'n pasted, and take the two sections "Stiff Spine Reaction" and "Weak Spine Reaction" and REVERSE them.

Edit: I just used Paint Shop Pro for you and cut/pasted/reversed the two Spine Reactions charts. Print this out and keep it, it'll help us lefties keep our bows tuned. ;)

RE: Broadhead tuning
 

Bigcountry were dealing with a fellow who is new to bow tuning/broadhead tuning. I can bombard him with bare shaft tuning, paper tuning, walk back tuning, and then get started on arrow tuning, fletching configuration etc, but what he needs is to get close to on track then we can debate the merits of paper vs bare shaft tuning.

RE: Broadhead tuning
 

thanks for the advise butcha...but i look at it just to move the rest the direction you want the arrow to go...and i was shooting to day and my broadheads and P heads are shooting 1 inch groups together...for some reason its was the oppostie of opposite...i was moving my P head and my broadhead stayed the same...its weird but it worked

RE: Broadhead tuning
 

so basicly i used the right hand chart for my bow and it worked great????

RE: Broadhead tuning
 

Yep, I know many a new tuner who has wasted hours on paper tuning. Including myself. In fact, he can follow the BH tuning chart without even touching paper, and come out better. No debate about it.

RE: Broadhead tuning
 

Hmmm, that is weird. But, hey, it worked for you! :D I was fortunate enough to have a bowshop about 1/2 hour away and got my bow all tweaked, tuned, and perfectly setup - by a fellow lefty bowhunter.

RE: Broadhead tuning
 

yeah, your very lucky to have a bow shop close by...the closest one to me is cabelas in Conn. about a 2 hour drive...i've tryed bow shops around me but everytime i go in and have them look at something they have no clue what it is...or if i have a question they look at me like i have 1,000 heads...there mostly just gun shops with a little archery room in the back

RE: Broadhead tuning
 

Some great advise there , very true , if you plan on hunting why bother with anything else , IMO hunting rigs are MUCH more critical of tune , and this is the tune they require .

RE: Broadhead tuning
 

No not really. The key is a properly paper tuned bow. Most people really don't do it correctly and then have to make a lot of adjustments later. If properly done paper tuning will almost always get you very close to where you need to be. I have done it all, bare shaft, walk back and just done the tuning chart. The fact is that paper tuning not only will have your arrows shooting better, but will help you to understand what minor and major changes in your form, rest position, nock point location will do to arrow flight. Again the key is proper paper tuning. The other methods work, and work well, but paper tuning will show you things that you won't see right away using other methods.

RE: Broadhead tuning
 

Not really. What most people don't understand is papertuning is not sensitive enough to really tune a bow. But most people don't understandthat long ranger broadhead tuning and bare shaft tuning is much more sensitive and works better. Most people like the paper because its simple, and see shops use it because its simple. But most people do not understand this.

RE: Broadhead tuning
 

I guess we will have to just disagree on this one. I find paper tuning to be very sensitive to changes in rest postion, hand postion, shooting form etc. Like I said though I use a combo of both, but I rarely have a bow that was properly paper tuned that won't shoot broadheads and field points to the same impact point, provided the arrows have enough fletch to control broadheads in the first place.

RE: Broadhead tuning
 

I was under the impression that most shops use paper tuning because they are limited in space. If you only have 15-20yds to shoot in it would be hard to walkback, group or even bareshaft tune with any effectiveness. Paper tuning IS easy but that does not mean it can't be effective if done correctly. No tuning method is effective if done incorrectly. If a shop only has the short range to work with better to papertune than nothing at all.

RE: Broadhead tuning
 

I agree bruce, not too many shops are going to be able to tune bows at 40 yards BH tuning. Its just not practical. I dont' blame them. I can move a rest 1/32" and may or may not see difference on paper, but I sure can see it with a bareshaft shot at 35 yards. And sure can set it with a thunderhead say at 50 yards.

RE: Broadhead tuning
 

I hate to say it but, most shops don't know squat about tuning!

RE: Broadhead tuning
 

Yes, distance most definitely magnifies any tuning issues. One of the big reasons a person should learn to do these things for their self. Doing it ourselves we can takefine tuningto a level most shops can't approach.

RE: Broadhead tuning
 

LOL another big reason a person should learn to do these things for their self.

RE: Broadhead tuning
 

I sorta disagree. I know some guys do know but just don't care aboutcustomers equipment. I see thier equipment is done properly, thier peeps tied in nicely, so is thier nocking points, but then they did entirely different work oncustomers bow. I have helped out alot of people lately from shotty work from proshops. I sure don't know it all. And honestly, I don't get too picky anymore, because a compound is dynamic. I used to spend hours getting it perfect, and then after 500-700 shots, poundage might have creeped down, might be little out of time, etc.

RE: Broadhead tuning
 

That is an excellent point! In my limited experience I have found the same thing. I generally retune or at least checkthe bow tune every few hundred shots or if I notice it shooting "differently".
