Title: Bare Shaft Tuning
Post by: buckeyebowhunter on January 08, 2010, 10:50:00 PM
Hey guys today i attempted bare tuning my CX 150's. I have been shooting them out of my 50lb takedown. I tried several different field point weights but they seemed to fly the best with 175 gr points. But even so they were still flying with the nock right just a little bit. I was wondering how i can get these arrows to fly straight all the time. Is there something i can do to adjust the way they are flying, or am i just asking too much. Any info would be great. Thanks.

Try them with feathers it's nice to have them perfect bare shaft but while hunting your going to have feathers if there a little off bareshaft they'll be fine fletched if they were hitting sideways then you may want to adjust something

Robert,

There is any number of things you can do to arrive at perfect arrow flight with bare shafts.  Different field point weight is only one variable.  Try brass inserts to increase the FOC (both 50 & 100 gr.)of the bare shaft, which is in effect, just point weight any way.  Tuning your bow differently can have a profound effect, specifically brace height, but brace coupled with nock height variation and different point/insert weights are a lot of variables to work with, not to mention your best shooting technique.  Building out the strike plate or making your bow more center shot is another way of affecting a shafts spine relative to that bow, hence arrow recovery etc.  Keep in mind changing one thing may reset the whole set of variables.  As always with tuning, change only one variable at a time.  I have played with CX Heritage 150's and found them to be difficult to bare shaft tune, they seemed weak (relative statement) in spine and I had to go much lighter in tip weight than I otherwise would.  Bare shaft tuning will also accentuate all your worst habits, so you'll have to use your best technique to give it a fair shake (already mentioned).  When all else fails, go outside the realm of what you think should work, it never ceases to amaze me as to what unconventional combinations actually work for bare shaft tuning.  Also despite all the aforementioned, some shafts will just not work for you, through a given bow...try a different shaft, before you are totally discouraged.  Also what Moose eye says is true, fletch will correct for "not so perfect bare shaft tuning", but there is nothing like laser straight bare shaft flight for efficiency and confidence, IMO, fletch is just icing.  Keep trying, I have found that eventually I can get just about any shaft ,within reasonable spine, to fly w/o fletch.  It's fun and a great learning exercise.   Call if you'd like to talk more about it.  608.798.1103

Over the years i have found that I get the best results after I have found all the sweet spots on my bow with fletched arrows. In other words, get the bow where it needs to be....brace height, nocking point, string material and # of strands, silencers, etc. Once you have your bow figured out then tune the arrows to the bow. If your bare shafting gets you close and you are having trouble getting the flight you think is perfect try a fletched arrow with one of the broadheads you want to use. If the spine is off too much the broadhead will tell you a lot. In reality, a properly tuned bare shaft will show a bit weak. When you fletch it the fletching will make up for the slightly weak spine.

If I read it once I read it 50 times.  Go to  www.bowmaker.net (http://www.bowmaker.net)  click on tuning.  Try bare shaft PLANNING.  It takes the "form" problem out to the equation (somewhat).  

I have found the most important part of above is the broadhead tuning.  In addition, I don't use "groups" of bare and fletched arrows.  I use one fletched and one bare and put a marker (usually a golf ball) in front of the target, so that when I'm at full draw I put the tip of the arrow on the marker and release it hits the center of the target.  IF I feel I shot both arrow with the good form I feel comfortable making a change.

Right hand, left hand, draw length, LB, curve, center cut of bow?  Unless we now what hand you are shooting, we don't know if that is weak or stiff.   What is a little bit?  You could be really close.  Also remember that unless your form is really good you may not get a perfect bare shaft flight.
