http://bowmaker.net/index2.htm When you cut shafts,cut fletched and bare,each time.
It is a good idea to have a WIDE variety of point weights and verify with point weight before cutting.You will see this mentioned in the Bowmaker tuning information.
For you,right impacting bare shafts will mean the arrow is too stiff.Add point weight.Left impact means too weak-trim shaft length or reduce point weight.
These days,now that I am familiar with what carbon shafts I need,I get them all cut to 30" and tune by point weight alone.Not having to cut shafts,makes the process go very quickly.I keep an assortment of screw-on field points from 100-300 grs and even a few heavier.
It might not hurt to list your bow and all it's specs,plus the shaft you plan to start with.Possibly someone could get you in the ball park with length and point weight and then you could tune from there.
Don't sweat the process and don't get in a hurry to get there.It is a great learning experience and you can jump on here and ask questions along the way.
Always remember,change only one thing at a time-very important.
