75/105 four fletch

[Pine]

  Just found out it was originally setup that way for more cable clearance on a compound.
Back when they had two wheels and a cable guard.

Yea, but here it is from "Kelly" as per Roger Rothaaer, who was a trad shooter:

"The 60/120 degree 4 fletch alignment is done during fletching with the three fletch jig. Install two-hen feather and two cock feathers. The following instructions are for right-handed shooters. If you are left-handed, you will do the opposite for the hen feather position, only. First, put on the cock feather. Then rotate the nock indicator of your jig to the left (counter-clockwise) and install a hen feather. This is where if, you are left-handed, you will need to rotate the nock indicator of your jig right (clockwise). Now remove shaft from jig, rotate 180 degrees and return to jig. Put on another feather. Finally, turn the nock indicator back to the cock feather position and install another feather. Wholla!"

Lets remember we now have (Blitzenburger) jig which will set up for 75x105 four fletch as well as doing the method above also.

Holy macaroni I have a lot to learn... and i look forward to it

Pine, I shot 75/105 way before compounds and several of my friends did the same

Is 75x105 two feathers close together at the top,and two close together at the bottom? That's what mine is set up for,and I like them,get great flight.

CORRECTION TO ABOVE:  I was running 60/120* just like Mr. Rothaar, I believe.  75/105* makes some sense to me.  Might try some on my 3-D set this year.

So do you run straight, offset or helical Clamp?   I shot a 4 fletcher arrow at RMSG a couple years back, but did not inquire about the arrow..... just the bow I was running them through!

goingoldskool:

I asked the same question and was told to use just a bit of off set.  Seems like a helical clamp would be enough with out adding more off set on a Bitz jig.

Yes... that's what I have on my Bitz jig.

I like using 4 X 90. Everyone's mileage will vary.

Ok mine is a Bitz also. I really like this set up myself. I don't have to look at the nock or feather orientation,and they fly really good. That's good to know I need to write it down somewhere

For those of you using four fletch, which ever configuration, what size and shape fletching are you using ?

This is getting very interesting......

[Wudstix]

I'm thinking I could go from 5" to 4" fletching and gain feather to control broad head flight.

Wudstix:

You may be surprised that going 4/4" or 4/3" will work for the BH and believe it or not give you more velocity.  I worked out a cople of arrows (carbon) on Stu Millers calc and the speed went up....

[Wudstix]

Would probably work on tapered woodies, as well.  But right now all my choppers are for 5".  I'm happy with quiet arrows and good flight.  Moving from 160 grain BH to 200-250 BH.  Quiet Kills Not Speed!

I have shafts with 4-2” and some with 4-3”. I like the 2” best, but I compete in some IBO shoots, and they have a rule that you must have 12” of fletching, so that is why I have the 4-3” arrows.

Bisch:

I am looking at the same thing "IBO" rules.  However, with the right arrow I can see the 2" as being deadly indoors.

Wudstix:

Don't want to start a big discussion but, the arrows/fletching pattern in question for me are for 3D IBO shoots.  I will look at them for broad head use after I have shot them a good bit.

Speed on a well tuned and FOC'ed arrow works well for me up here in Yankee land on our deer which are in general bigger then yours down in the valley.  We don't have hogs here at home but on my numerous forays down into Brooks, Kenedy and Kleberg and Willacy County's has not deterred me from speed and sharp BH's.

Just sayin....

[Wudstix]

No worries, I just shoot what I'm used to and pick my arrows up on the other side.  Even went end to end on a 150# boar once, chalk that  up to luck.

Dad had a couple theories on the 60x120 spacing you described from Kelly's website.  One was that either way you put it on the string it is like shooting 3 fletch cock feather in, and that gives you quicker recovery from paradox due to the "parachute" type effect of hen feathers out.  Additionally, with 3 bladed heads (Snuffers of course😁) and 4 feathers you can rotate them in your quiver to get better fletching clearance in the bowquiver without poking new holes in the foam. He always shot big feathers, and I agree, I'll take the faster recovery that big feathers give over a few fps any day for hunting with big broadheads. 

I don't know for sure when he started using 60x120, but I have a picture on the wall of the big Ohio non-typical he killed in 1974 and the arrow he killed it with is on the wall under it, and its fletched 60x120.
