I have a Bohning jig.  I have the standard 3 fletch and what looks like parts to do 4 fletch 90.  I am thinking I can do a 60-120 by fletching 2 feathers then pulling it out and roating it 90 deg. to do two more making the 60-120.  Is this correct?  I don't see a way to do 75-105 with this jig.

Your jig should have 3 Allen screws near the indexer knob.
The bottom-most screw is your 75 X 105.

do 2 feathers with the 3 fletch settings. Pull arrow out of jig and turn 90deg's replace and start over.

Cock feather then left turn on knob. Turn back to cock feather setting and repeat.

You've got it right.  With the standard 3-fletch set up you just put on a cock feather and a hen, then flip the arrow and put another cock and hen. Gives you the 60/120 spacing without the need to change your jig.



I don't notice any flight difference between the 90, 75/105 and 60/120, so I just do what's easiest     It does work on skinny carbons too... I don't know why lots of people think you can't put 4 feathers on carbons?    :confused:

Great, thanks!  I will try the 60-120 first then maybe the 90.

I like the 4 fletch 90 on that jig

I shoot 4 at 90.  I would not over think the angles.

for low height fletches, 90x90 or 75x105.

for high feathers, 75x105 or 60x120.

i typically use 75x105, sometimes 90x90, never 60x120.

don't think any of this is gonna matter in the long run.
