Thanks

Matt

shaft angle in the butt always matters most to me.

And you have fairly straight shafts with 400 grains up front?  I like to tune a bare shaft so it shows slightly weak - 5 maybe 10 degrees off the fletched shafts. Do you have a picture?

Please don't get me wrong I'm not questioning your tuning I'm just trying to understand and gain from your experience.  While I haven't posted here a lot I have been playing this game for 10 years and like you have spent a lot of time and money tweeking arrows.

I am beginning to think that like hatchchaser stated earlier - a 32 inch shaft is a very different animal than a 29 inch shaft.  But, i don't know why that would be.

Thanks

I am shooting a 50 @ 32 Morrison recurve.  I believe Bob cuts past center.  Would building out my side plate let me put more weight up from?  This is an area that I know little about.

It is conversations like this that makes this such a great site.

Yes it would, but as Jason stated earlier it makes your setup more finicky or less forgiving.

I have had some success adding weight up front and stiffening the spine on GT 35-55's by just inserting a 1/4" dowel (from 3 to 5 inches in length) in the front of the arrow and pushing it in with the brass insert so that it lies right behind the insert.  Depending on the sizing diameter of the dowel it is either necessary to lightly sand or add a layer of cellophane tape for a snug fit. By this means I have been able to use some shafts that were too weak spined for any of my bows. I get about 27% EFOC and good arrow flight from a 53# @27" St. Charles TD longbow that is cut about 5/16 from center. Arrows weigh about 625 grains using a 50 gr brass insert and 260 grain point.

ye of little faith.      

messing with arrow tuning is an 'experiment of one' because the archer is a significant part of that well flying arrow equation, not just the physical gear we love to chat about.

tweaking the many of the aspects of the arrow and the bow is the first and foremost route to go for a well flying arrow. there are no guarantees and your results may significantly vary from mine - as it could/should be.

a bidirectional butt tells the truth, too.   :D  

i read in the latest tbm where fred eichler hunts with essentially the one bow he's had all his bowhunting life, a 54# @ 30.5" palmer, and his axis arrows weigh just under 500 grains.  his comment was "I've had it pass through a moose with no problem".

to each their own and that's good enuf for me.

I made an arrow for my son's 55 lb bow.

Gold Tip Ultralight Entrada 400. 7.4gr./in.

513 up front and 781 gr. total weight with 32.7% UEFOC.

It is wonderfully and fearfully made.

yeah, but how well does it fly?  

[Matt_Potter]

Rob,

Thanks for all the feed back.  I can get the Axis to tune up to 275 (100 insert and 175 head) past that and I'm not happy with the flight.  This gives me 20% FOC and a 590 grain arrow.

I am going to switch to a standard insert and a 250 grain head on my next batch.  This will give me a slightly lighter arrow (580) but, more FOC.

I could switch to a Maxima 350 which has the same spine but is 31 gains lighter to get more FOC.  But, I think I'll call it good and go try poking things with my sharp stick.

You guys run a GREAT site.

Matt

tweaking gear in the off season can be fun and rewarding (and help with 'cabin fever'    ).  

it sure helps heaps to have disposable 'fun money', too.  :D

[Richie Nell]

Rob,
"yeah, but how well does it fly?"

What?  It flys perfect!!!  I wouldn't have mentioned it if it didn't fly right.

You are not from the "light, fast" camp but that is what they imply so much of the time.....That you can't have everything in the same arrow, for some weird reason.

But you can and that is the only option for me...AND YOU I'm sure.

[Elk whisperer]

shoot a AD trad 31" 75 brass insert 200 point for a 630 gr arrow out of a 58@30 schafer seem to fly well I would think you would be ok
