Title: 4 fletching preference 60/90 or 75/105
Post by: TheArc on December 14, 2007, 04:05:00 PM
I have a dozen arrows to fletch today and have decided to go with 4 fletching as a solution to better picking up my arrows in flight in low light with my fading lamps. I couldn't find any threads discussing the attributes or advantages of either fletching distribution. You four fletcherers(?) please lend me your thoughts on which you prefer and why. Holiday regards to all.

Arc:
You will get the best clearence with 75/105 there is not such animal as 60/90 you probably mean 90/90.

I like the 60/120 best personally.

I like 60/120 but usually fletch mine up 90/90 only because they are easier IMO to replace individual feathers.

Without a doubt, 60/120 for best fletch clearance and lowest nocking point.

My mistake, I see that the two four fletch options that I have are 4@90 or 4 @75/105. So Bob you like the extra clearance the more extreme angle of 75/105 affords when passing by the side plate and would you say it doesn't create less clearance aginst the shelf?

Deadsmple, that is a good point about the easier access from the greater distribution, on one side at least I guess for stripping,cleaning and gluing. I am actually more concerned with how it effects the arrow at release than maintaining the arrow but I like that consideration all else being equal.
Thanks as always for your good counsel gentlemen.

I been using 4@90 for 38 years, though I did use 4@75/105 for a brief period but went back to 4@90.

Mark

I fletch my arrows 4@90, and have had no problems.  I use 4" feathers, and I find arrow flight improved from 3  5 1/2" feathers.  I never really tried the 75/105.  Probably will eventually.

Talk to you soon.

Mark

A lot of clearance problems can be solved by the right spine arrow shaft.  In most cases,  that arrow has to bend around that bow to get out clear and on track.

I can see absolutely no difference in arrow flight between 75/105 or 4x90 out of my bows, both fly perfectly. Haven't tried 60/120 but see no need to, unless I get bored one day and need something else to test. I use 4x90 for the same reason Deadsmple does and honestly, I like the symetry.

I agree with Mark: I do prefer 4 fletch whole heartedly, and am completely convinced in my little mind, however small it might be   :rolleyes:  , that it's superior to 3 fletch. Espcially when coupled with lower profile feathers.

I use 4X90 on easton axis shafts and have no clearance problems out of my Cari-bow recurve.

Thanks all for the input. Now to fletch.

I space them evenly.....and here's why.... a 4 blade boat prop is spaced evenly for a very important reason....if two blades are too close together, one will rob water from the other, and the prop will not grab water evenly and it will loose stability and cavitate....like prop wash in jets.

If you have feathers too close to one another, one will grab more air than the one behind it....defeating the purpose you are after.

Never had clearance problems with them space evenly either....I like the 'no look nocking' feature though.

Would like to reserruct this one..

I have the option of (4) x 90 or
75 x 105...

For the first pass, which one should I try?

4" parabolics the way to go??

Thanks for the help..

I've always used 90 degree spacing. I figure the reason 3-fletch are at 120 degrees is to space them evenly around the shaft, so why not do the same with 4 fletch? Clearance has never been an issue for me.

I use 4 at 90 and never had a problem, plus as Terry said..they are better balanced....also just look better to me.

I prefer 90.  I like that prop analogy.

I USE 75/105 GREAT FLIGHT. I HAVE USED 4@90 GOOD FLIGHT. I THINK IT IS ALL IN WHAT WORKS FOR THE SHOOTER.

Sergio,

I didn't say anyone was doing it wrong...its just that each feather grabbing the same amount of air evenly is going to be more efficient in stabilizing an arrow than if the two lagging feathers are not.  It wont work with a boat prop for the very same reasons.

If you are getting good arrow flight...you got good form....so go with what you like. If its worked for you for 31 years, then I recon it works for you.  

No worries.    :thumbsup:

Hi terry; i was just " joshing " around. Ment no offence by My comment and actually i shoot vanes a lot especially during moose season , which is perpetual rain where i live and hunt and am using 75/105 , because arrow floght seems cleaner. I actually think that the " prop" theory has merit and am going to try it. happy Holidays to all.
