And my all time favorite …

“It is not the critic who counts: not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself for a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.”- Theodore Roosevelt ; “Citizenship in a Republic,”

Speech at the Sorbonne, Paris, April 23, 1910

in reply to: A&A Fletching #58326

I’ve posted this on other threads but it is worth re-posting here too. The concept of using the minimum fletching ‘drag’ required to stabalize the arrow’s flight is nothing new.

“The arrow has been likened to a ship; the feathers corresponding to the rudder with which the ship is steered. If the rudder is too heavy, it slows the ship down and may even cause it to sink; if it is too light, the ship will roll and pitch and be out of control.” – From translation of the 500 year old text on Arabic Archery

Ergo; if the fletching is of a greater amount than the minimum required to stabilize the arrow’s flight all it does is slow the arrow down and ‘cause it to sink’.

Steve, King has it spot on. The natural curve of the feather imparts all the arrow rotation required. The purpose of applying it as a straigh fletch is simply because the additional fletching pressure (read that as ‘drag’ on the arrow in flight) is not needed with the EFOC arrows.

I though it worthwhile to copy this post by Kingwouldbe over from another thread. It’s a very important factor to realize before you start trying the A&A fletchings.

Kingwouldbe wrote: After several PM’s I think I need to share or clarify a few things.

You can not just take your regular arrow and cut the feathers down, You must have EFOC to get the results we are talking about.

A EFOC arrow is stable by design, therefor needs or requires less fletching to do the same work 5″ feathers do, so that you under stand a little better, it’s like putting flu-flu feathers on your hunting arrow 😯 why in the world would you do that, it makes your arrow LOUD and SLOWS it down, down range, yet, you can pluck the arrow all you want, it will fly straight, even if it’s not tuned to the bow, it will fly straight, as the HUGE feathers masques or covers up any errors in the tune.

No one would hunt deer with a flu-flu arrow with a broadhead, will it straiten your arrow up with a bad release, it sure will, but at a cost.

If you tune your regular hunting arrow, you do not need flu-flu feathers to stabilize it, it’s the same with a EFOC arrow, you just need less feathers to do the same work of 5″ feathers of a regular hunting arrow.

I have heard a few people say, they want more feathers for hunting to stabilize there arrow for hunting conditions, and I do agree, for REGULAR arrows, however with the EFOC hunting arrow, it is not needed.

We are NOT taking a regular arrow and cutting the feathers down, we are building a whole new arrow, from the ground up.

Hope this helps

The only set features of the A&A pattern are: (1) The fletching has a straight, vertical cut at the rear, with a 1/2″ height; (2) it has a straight taper from the rear to the front; (3) it is applied as a straight fletch, with no helical and no offset; (4) it incorporates the turbulator placed 1/4″ forward of the fletchings leading edge and; (5) it is individually tuned to the particular EFOC or UEFOC arrow you are building up – that determines the length of the fletching you can use.

Smithhammer wrote: Their arrows used fletching cut to a length of 5 centimeters (1.9″). Average overall arrow length was 60- 80 centimeters (23″ – 31″).

It’s interesting that they chose to use such short fletching, given that they used the feathers of a large native goose, which could have offered longer fletching options if needed.

(Selk’nam fletching and points:)

Even at the very short feather length it appears that those arrows have only 2 fletches. Shame they didn’t look at arrow FOC.

Great autopsy video, King. I particularly like the clearly shown “L-shaped” cut through the lungs on the second test shot and the ‘starburst’ cut showing on the liver, from the kill-shot. Superb video work.

I wish I had been able to do videos during the Study but didn’t for several reasons; I’m not tech-savvy enough to operate one, couldn’t afford a good video camera and, as you’re learning, it takes a lot of effort to carry along AND use all the things one would like to when working in the field. With all the assortment of arrows and measuring equipment I was always carrying it was just more than I could manage. At any rate, I’m immensely grateful that you are documenting on video so many of the things I’ve tried to capture in still photos. Unless one has done a lot of field testing it is hard to grasp the extra effort required to document the shot outcomes. You have my most sincere thanks for the great effort you’re putting in.

in reply to: How many bows do you have? #52960

Too many, but a necessity at times, for the testing. When it comes to serious hunting, over the last quarter century I’ve used very few. For hunting I tend to stick with one bow; one that I have developed a special relationship with and am totally familiar with.
