Title: Adcock Fletch - the turbulator one
Post by: Flatout on October 17, 2008, 11:37:00 AM
Thinking about trying to duplicate this fletch  http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=057257;p=20#000289  However, I'm a newbie and am wondering how do you make a feather like this?  The choppers that I find online don't have that shape.  Do you just cut with a scissors?  Also, could I just buy pre-shaped 3" banana, parabolic, or shield and have the same results?  Also, I am working up a set of practice only arrows for a light weight 36# bow (no broadheads) but low FOC.  Could this same shape and style be used for these arrows - shucks maybe wouldn't need a turbulator for it.  Where do you buy pinstripes?  Sorry for the many questions.  But, I do appreciate any help.

China?

I dunno if he'd be interested but I know a chap who will alter a raptor feather chopper to make the A&A feather design.

PM me if you're interested and give me an actual email addy and I'll send it to the chap and see if he is interested in building anymore! I got one through the St. Judes auction and he auctioned off another one I know of!

That's a very easy feather profile to make a chopper for.  It took me less than an hour to build my first chopper (after a few beers no less).

You could get the pinstripes in a hobby store that sells RC Planes and such I bet.

"Where do you buy pinstripes?"

Automotive paint and body stores

Might be more work than people would like but one or two layers of string wrapped over the shaft with a layer of clear fingernail polish has the potential to look very nice!  (Think of the wrappings on very nice fishing rods or tying your own flies.)

Is this stuff going to be covered in Ashby's next report...or will it only be EFOC/UFOC?

I will PM you Doc Noc.

Jeremy, could you show me some more detail?  That looks like a hacksaw blade.

Still wondering if any old shape back of the turbulator wouldn't work fine.  

Thanks for the help.

Hey guy's I know this is going to just slay some of you and please I'am not being a wise guy here.What in the heck are you guy's talking about.Is it a fletching ??? thanks dudes bowdoc

bowdoc-ther is a long thread about very short fletching preceeded by a airflow interrupter 1/4 inch in front of the fletch-it interrups laminar flow and supposed to stabilize the arrow better.Flatour has a post for it in the first in this series

Since I have a pile of 5" shields I just measure 2.5" from the tip and cut ninety degrees with quality scissors, yields a 2.5" feather 0.5" high at the back, basically a right triangle.

Real bowdoc, yes it is a fletch some are using, the idea is to minimize the fletch size/height which quiets the fletch and robs less speed. I use them with the turbulator and they stabilize my broadheads very well, even when wet.

katman thanks.I was not sure.I know I have some super old arrows that have broadheads mounted on them.I beleave they were from around the 1920's.But some of them guy's shot a very short(3 1/2"-4") 4 fletched arrow to stabilize the broadhead as soon as possible.I did try out a few 4" 4 fletch myself and they seem to work fairly well.Again KM thank for the heads up...bowdoc

Will the turbulator help on flight on regular fletch you think?

Now wait a minute.  EFOC is supposed to enhance flight and improve penetration.  It supposedly allows for less fletching, so why does one have to have this little tail?  Now I'm not opposed to a little tail....it's the principle of the thing.

And....shouldn't it be called a deturbulator.  Or perhaps a misinturbulator.  Whatever happened to just tuning your arrows 8^).

Excuse me now but I have to get back to finalizing the design of my Testiculator.  Congress is in need of some of those.

LOL, You guys are great!  :)  Guys, I have no clue what this is doing at the low speeds we typically shoot for hunting arrows. the good Doc picked up on what I was doing with flight arrows which could be an entirely different ballgame. Instead of relying on a lot of subjective opinions, I/we intend on doing some wind tunnel tests at our hunting arrow speeds looking at "stability" mostly between different FOC's but fletching size and what if anything turbulating does. I am certain no matter what size fletch is used it will make the fletching more effective without increasing drag. That won't be sigificant at 10 yards but the further out we get, the more dramatic it will be. When trying to explore and understand, riding in the middle of the road won't tell you much.....O.L.

I've never seen this type of fletch. does anyone have a pic?? just curious. Skippy

It's all good O.L., some of us are just mired in the 20th century 8^).  Grumpy old men, if you will.  I think it's funny that anyone who plays with stick and strings talks about stability.  :bigsmyl:

imskippy,

Follow this link  http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=057257;p=20#000289   Its in Ashby's first post.

O.L.,

Any idea why Ashby selected the fletching shape that he did?  JC (earlier in the 36 page post) was finding banana fletching to be really quiet.

I really appreciate you guys who are advancing archery, keeping us informed, and doing it at no cost to us!  Thanks!

One must be careful however.  Nothing wrong with new feather shapes, front loading, single bevels, etc.  It's interesting and sometimes very beneficial.  But keep the line taut because Hollis Allen, Tom Jennings and Pete Shepley were advancing archery as well.   :saywhat:

Yeah, the same could be said about fiberglass and epoxy...and I bet someone feeling a little self righteous did when first introduced.

Gee...O.L and Dr Ed are playing with way's to achieve improved flecthing correction..NOT a new arrow launch platform or a lazer bow...lol
