First off, thanks to the bros who clued me to Stu's Arrow Calculator.  What a great app, I fiddled with it all last week.

It was on the money, too.  I set up some 2213's I had laying around that with 125 grain points and a little diddling, came out to within .2 lbs spine of my primarly bow's calculated poundage.  The result was the best arrow flight I've gotten to date, far superior to any arrows I set up before. Even better, I got more than acceptable flight with all my bows which fall within a few lbs draw of each other.

I have several dozen 2117s on hand and found I can get them within .5 lbs with 145 grain points, which will be a bit heavier arrow.  I anticipate they will fly as well once the points arrive.

It's going to be a long Winter and there is much fiddling to be done before Spring.  This leads me to my question in regard to carbons.  The calculator needs additional data to
cipher out carbons, so does anyone have the deflection data for some carbons handy?  

Specifically I'm looking for the data for 29.75" 4560 (.400) CX Terminator Hunter Selects...

BTW, the link to the download should be stickied somewhere here on Trad Gang...

Where can you find this Calculator?

This should send you to the download page:

Apparently your computer needs excel for it to work.

Or go to openoffice.org and download the free spreadsheet application. You may have to update some Java but works great.  There is a a variation of 5lb if you set center cut to 0.  For some reason openoffice adds 5lb of spine just subtract 5 lbs and your good to go.

Have fun

Les Heilakka.. any problems with download please let me know.

ND try looking here

Thanks Les,
I'll try that.

Yes, fortunately my wife had a copy for her computer.  Once I had Excel on, the app worked just peachy...

Thanks Met, that takes care of shaft diameter and GPI, now I need to find static spine (I don't have a spine tester handy or I would do it myself.  I could be wrong but I'm thinking the app may be looking for something other than spine 400, which is assigned to most all 45-60 lbs rated carbons..

Thanks for the link.  Nice calculator.

The ASTM spine for Carbon Express Terminator Lite Hunter Select #4560  is .398 which gives a amo spine of 79.2.

Thanks, but the Lite Hunter is slightly different than the discontinued Terminator Hunters of which I bought several dozen before they were dropped.  Too bad as they were great trad arrows as far as carbons go, tough & heavier GPI than most available even now.  

Probably the closest match in the app are the Heritage 250s....

Here are the specs on Heritage. I shoot the 250's
convert the spine to AMO using the calculator.

Thanks.  Did some diddling and  found the CXTH falls closer to the Rebel 4560 in spine but closer to the Heritage 250 in weight.  They have a full length "pre-built in FOC" Buff Tuff outer wrap which gave them more GPI weight than about any carbon at the time, until CX came out with the Heritage.

as far as dynamic spine, they come out less than 1# difference with a 29.5" shaft, 50 grain insert, 125 grain point, 7" cap wrap, and 4" feathers...
