help Building an Arrow

[wildwilderness]

Finally getting into traditional. The bow is a 3 piece takedown recurve, 62",  53# at my draw lenghth of 29".  I want to make arrows for the bow.  I want to go with carbon arrows.  I also want to keep the price on the lower end.  I have read all the stuff for newbies and tuning, but I need a starting point. I think an overall all weight of 500-550gr would be good.

First I need to select a shaft, I have been looking at GT trads, or CX heritage.  What shaft length should I start with? and what spine?  

I like the idea of using 100gr inserts to get the weight up and out front. Then tuning with different weight tips. the GT weight system is an option if needed? How do I get the inserts to stay in while testing without cement?

How about fletchings? 3 or 4, how long, 4 or 5 inch?

Any ideas would be appreciated.

You will need the GT 35/55 or go with the GT 55/75 if you want an EFOC.  The Hertiage 150 will work with or w/out the brass inserts.

My standard fletch for the arrows are a 5" shield cut feather.

First off where are you in CO?

What bow are you using and what is the Center Cut?
Are you using a fastflight string or B50 dacron?

Initially the GT TRad or the CX Hertitage will work.  The biggest factor in knowing how the side plate is cut and where it is from centerline.

I'd go with 3-5" Fletching.  Shape is a personal thing.  Parabolic, sheild or banana?

It will be know problem getting a 500-550 gr. arrow.

What broadhead are you wanting to use and weight?

Get this info and I can get you a better idea of what you will need.

I am in grand junction, the bow is a Jimbow, I have shot with him, center cut, and for now a dacron string.  Just keeping it simple to start.

I have not decided on a broadhead or tip weight yet.

Since the bow is center cut and with a hair sideplate it should be around +1/8".

I plugged in the GT 55/75 and CX Hert into Stu's Calculator.

Your bow looks like it needs a dyanamic spine around 53.1#

GT 55/75 specs for a Dyanamic spine of 53.2#

This gives you an arrow around 514gr w. FOC of 18.9%, 9.3 gr/lb

30.6" BOP
200 gr head w/adaptor (125 gr head w/ 75 grain steel adaptor)
15 gr insert
11 gr nock
5"  Feathers


CX Heritage specs for a Dyanamic spine of 53.3#

This give you a 573 gr. w/ foc of 16.9%, 10.4 Gr/lb

31.25" BOP
200 gr head w/ adapter (125 head w/ 75 gr steel adaptor)
11 gr insert
9 gr nock
3-5" Feathers

This will get you in the ballpark.  Best to shoot bareshaft and see how the fly then cut down a little at a time until you get the correct flight.

Thanks for the help

so, you would not recomend using the brass inserts? Would I just use screw in 200gr field points?  or would it be the same to use a 100gr insert and 100gr screw in pts and broadhead?

[MSwickard]

Either way.  Brass inserts are on the spendy side compared to steel adapter. I've used brass inserts when I use an Al adaptor.  You can achieve the same thing using the factory insert and using a steel adaptor.  The steel adaptors come in 75, 100 and 125 gr.

I'd find the BH you want to shoot and work the weight up from there.  A lot of different ways to achiieve the same ends.
