Stu' Arrow Calculator?

[Capt. Dave]

I am wanting to build some new arrows how accurate is this program.

[snag]

It is a very great aid in selecting shafts, point weights, etc....as long as you put in the correct information. If your shelf on your bow is cut to center and you put in "0" you are putting in incorrect info. This is because of not figuring in the strike plate material thickness. I for one am very thankful to Stu for sharing this wonderful tool with us to help us as a starting point.
I guess what it comes down to is how "tuned" do you want your arrows to your bow. I like to use the calculator sometimes to get me to a starting point. Then I bare shaft them to fine tune them. But that's a whole other thing.

For my bow, not very.

However, since by tuning I know what my bow likes, I can use it to figure out other arrow combinations that work as well. So IMO it works extremely well at comparing one arrow to another but not so well at matching arrow to bow.

Think of it as a tool to suggest a starting point. It's really no different than getting an educated person to give you a starting point. It's only as accurate as the information you input. Like Snag says, the better measurements you make regarding all of the variables, the closer it will be.

That being said, whether it will be accurate for you depends on you. If you snap shoot, creep forward at release, have a rigid string hand, torque the bow, torque the string, have a bunch of stuff on your string, etc, can all affect the accuracy of the calculator.

Again, I see it as a starting point, just as I would if I went to a pro shop and talked to a professional. It has been accurate for me.

I almost hate to ask for fear of looking like an idiot ... but is Stu's calculator located somewhere on this site where I can access it?

[Shawn Leonard]

I find Stu's Calculator does not get me even close and yes I have entered everything right. He always has me well overspined as do most spine charts. Shawn

look at my signature.. direct links..

Stu's calculator is a great tool.

Stu's calculator is a great virtual "what if" progam since you can see if different spined arrows and point weights will work without having to buy them first. I always fine tune by raising or lowering the brace height.

I have to run a -6 on the calculator for it to be accurate for me.

Stu's calculator is in my humble opinion one of the best things to happen to traditional archery in the last 10 years. I use it and find that 99% of the time it is real close. Just because its a calculator doesn't mean it is perfect but its a beginning. Good job Stu!!  

[Spectre]

Works pretty good for me. Like others have said, it gives me a nice starting point to tune from.

Thanks Les ... When I first got into this sport a couple of years ago, the previous owner of Sipsey River helped me out tremendously with selecting and tuning shafts.  I am very grateful to him, and for all the help this group offers each other.

It is dead on for me and that has been with multiple bows and multiple arrow combinations. If it is not accurate for you it ought to get you in the neighborhood at least.

I find it very helpful. I put the numbers in and come up with a "starting point" arrow. This arrow is usually VERY close and only needs a minor tweak here or there to make it perfect.

I like stu's calculator a lot too. It usually gets you real close if you have no idea where a new setup should be. I don't think there's a better way to guestimate shaft size before buying. I always lean toward buying a heavier shaft though because you can always load a ton of weight on the front until you're soft enough. Also, that way you have a really massive arrow which is great for hunting and trad bows in general.

Good to see the majority of users benefit as I do from Stu's efforts.
