Dave,

Thank you for the reply. I mean this in the most non-confrontational way imaginable, with all due respect and keeping in mind that I am a newbie: so what is the dynamic spine calculator used for? I have always been a numbers guy. I can explain myself in numbers 127.479 times better than with words 😛 . I plugged my arrow numbers into it, got an FOC that seems acceptable, but a spine that is WAY off (with the Tusker Concord Broadheads someone on the forum suggested 😉 ). I still understand the “get your arrow to fly perfect and worry about the rest after”, so is that what I should be doing with the spine calculator? If I am truly making this way harder than it should be, just tell me to go pound sand and I’ll go practice instead of number crunching. Thanks again to everyone for all your help and patience. It is truly appreciated. Be well.

Tombow,

I agree completely with you (and Dave above where he says “So the trick is to find the lightest possible shaft that can deliver the necessary spine…”). the point I was making is that having a decent FOC (like may arrows at close to 25%) and having them balanced with the bow according to Stu’s chart if pretty darn difficult.

The calculator says “These two numbers should be nearly equal (within 2#). Fine tuning can then be done by adjusting the bow’s brace height.” My numbers are about 25# off. Then I am planning for the longbow I have on order and it looks like I will either have to use a steel rod for a shaft or give up a significant amount of FOC.

Using the calculator with the stats above on my 52# LB, I get arrow spine of (+/-) 22 and bow spine of 69.5. I am estimated at 158 fps and 38 ft/lbs. and an FOC just under 25%. Going to my new (WIP) bow gives me the same FOC, but bumps my speed to 192 fps and 56 fl/lbs. But my “spine must be within 2#” goes to 22 arrow and 97 bow. I understand that a good flying arrow can come out of a bow/shooter combo that is over/under “within 2#”, but such a big difference? I guess the numbers are just scaring me.

Going to what Dave said, I choose a 300 spine carbon arrow with all else being equal (for the 80# bow, I am using 78# as input). I still get 52# arrow and 97# bow. So my question is (I guess) how much can the spine suffer with FOC, and if it just depends on the shooter, why bother calculating it in the first place? Again, very new at this, and I actually want to get this right not just for me, but for the animal’s sake as well. Thank you all for your input. Be well.

I guess that’s where I get into trouble. My arrow dynamic spine and bow dynamic spine are NOWHERE close. If I decide to tweak the arrow to match the bow, I get an FOC about 10%, which is not acceptable at all according to the study here. I cannot tweak the bow (LB 52@28 or Hybrid {R/D} 50@28 ), so my only option is to be grossly mis-matched? Furthermore, I am getting a bow that is close to 80#. To have 350gr (250 + 100) up front, I cannot find a shaft that will handle it (according to the dynamic spine calculator) or an arrow that has acceptable FOC (>18%). So what am I doing wrong? Be well.

😆 😆 😆

Sorry, that one got me.

I was doing some calculating, and I am still having an issue. I am starting to think it’s me, but I figure I’d check. I have a 30″ 2016 aluminum arrow at 10.6 GPI (grains per inch). My fletchings are 5.8gr, so round to 18gr for 3. I have a 250gr broadhead and a 100gr insert. I tend not to follow directions well (and I don’t have my arrows in front of me) so I did not measure the shaft, but I figured I would use some math. Here’s what I got:

Total weight = 686gr (arrow = 318 {10.6*30} + 18 for fletching, 100 for insert and 250 for the broadhead)

Center of shaft is 15″ (30/2)

Center of weight would be the point at which both sides weigh 343gr. Here’s where it gets weird. Looking at the feather side, I would subtract the feathers from the [half] weight and get 325gr. That is how much shaft is on the non-broadhead side. So, divide that by the GPI and I get 30.66. Basically my FOC for this arrow is BEYOND the arrow.

HUH?????

So, other than my math being off, what am I missing? Keeping with arithmetic, I cannot find 15.66” on Dr. Ashby’s FOC chart.

Help!

Be well.

Dave,

Thank you for reminding me of a question I had. I agree about the jerky BTW. Actaully great jerky, otherwise, not so much. On to the question: What are thoughts on the ethics of shooting birds (like geese, actually, geese) on the ground versus on the wing? I am strictly talking about filling the freezer (dehydrator, actually).

Next, how about bird hunting in general? In have NO experience, but I have seen [previews of] wing-shooting videos that show pheasants flying away with an arrow sticking out of them. Somehow makes me lean towards the old smoke-pole.

Sorry if this is off topic. Be well.

Roger,

I know it’s not what you’re looking for, but here’s my “quiver”:

For $30, it serves me well. Keeps quite a few arrows (so long as they are field points, 2-blade broadheads or the like, no Judos or 3 or 4 blade broadheads). Also keeps my bow stringer, glove/tab, lunch, water, book, …

Again, I know it’s not what you are looking for, but since no one else was posting pictures… 😉

Be well.

Ditto here. Never mean to offend. If something can be taken 2 ways, I ALWAYS mean the one that doesn’t offend. Actually, I had to put my foot in my mouth on the same subject (not archery related) today because I assumed that just because something is on PBS, it must be “L&%*@#al”. I really do enjoy these forums. I hope I have not offended anyone. People do not always agree, but that doesn’t mean they can’t get along. On the flip side, I do not take offence. If someone has a suggestion or a criticism, I am only grateful for the advice. Anyway, hope to hear from you all soon. Happy holidays to you all. I’ll start a new thread as it gets closer to my Florida Hog Trip. Be well/.

in reply to: Dumb Question… #39975

Thanks for the info. So far, the “locomotive versus pick-up” example makes sense. I am still in “gun mode” in many ways. A 240gr .44 Remington Mag cannot compare to a 55gr 5.56 traveling at 3X the speed. I guess I have to get into “archery mode”. My E=0.5(M)V^2 seems not to hold up in practical use. Well, back to the study guide. Thanks again all. Be well.

How bad are we talkin’? Mid 60s? 😉

If you tried the basics (and it appears you have) take a look at some other things, i.e. clothing (not shoes), fitness, etc.

As far as clothing, I tell my kids this all the time in the fall. If your hands are getting cold outside, put on a sweater. They look at me weird, but if you are keeping your core warm, the extremities are much easier to regulate and respond much better. Also, don’t forget a hat appropriate for the weather.

For fitness, have you had a physical in a while? I am not a Dr, nor did I stay at a Holiday Inn Select, but there are issues that can limit circulation and thereby make you feel colder than usual.

For the “etc” part, remember not to be a statue. You don’t have to do jumping-jacks in the stand, but remember to wiggle your toes, or maybe half-stand just to get the blood in your legs moving and don’t ignore your arms (unless you shoot the bow with your toes). This helps quite a bit when stationary for a long time. I am sure others will have more (and probably better) advice. Good luck. Be well.

DWC: Agreed. I also think that misguided organizations like PETA are helping quite a bit. When they let their “idiocracy” show (naked protests and things of that nature) many people who may not have had a strong support for hunting now at least listen to when hunters offer rational arguments to wildlife management, and they pay even more attention when they see hunters acting ethically. They finally start to really pay attention when they see how areas that have well managed wildlife are much less prone to [animal] hunger, disease, accidents like collisions with automobiles, etc. But it all hinges on us not turning those people against us. Like you, I very rarely mention anything about hunting. It has gotten to the point that I simply don’t want to put up an argument. I try to present facts, but there are always the fanatics who will yell and scream and not listen to a work you say. So all I can say is, we must be doing something right. Hope we can keep it up and keep the slobs at bay. Next, as tailfeather, BuckyT and others have mentioned is the “Big Pimpin” of our craft. Only way I can think to combat it is to not tune in to the shows, not to buy the products [I know I am a bit guilty there] and to keep leading by example. Just IMHO, of course. Be well.

Thank you all for the advice. Looking forward to giving it a try. Arne, watched several of your videos multiple times. Great teaching aid. Moral of the story is “anything easy usually isn’t worth doing”. I have the perfect bow to practice with and I will try the paint can in between. Thanks again. Happy Holidays to all. Be well.

in reply to: Newbie with an Arrow Question #37048

kellenlogan,

Nothing against Cabela’s, but may I suggest you try 3RiversArchery.com or TradTechArchery.com or even KustomKingArchery.com. Again, nothing against Cabela’s. I go there every now and again. But the places I listed (and there are many more that are just as good) tend to cater more to the trad folks. They have a bigger selection and prices are on par, if not better. Shipping takes a few days, and is usually pretty quick. Shipping cost is ofset by the price of gas (I live 30 miles from my Cabela’s, so 60 mile round trip at 20 mpg at $3.30 per gallow, well, you do the math). Again, I can’t stress enough that I have nothing against Cabels’a, nor do I work for any of the places I mentioned. Just want to see you get the biggest selection to choose from so that you can make a good choice, and Cabela’s is pretty limited for trad stuff, especially hard-to-find stuff. Hope this helps. Be well.

Arne,

Thanks for the advice. As I said earlier, I went out to the range and tried to “loosen the shooting fingers”. I am actually having issues with that. I can’t seem to “let go” fast enough. I am not sure how I am doing it, but trying to consiously let my fingers relax winds up with me actually moving my string hand forward as I “let go”. Any suggestions on how to practice this / aquire the skill? I am really trying to get consistancy down, even at 10 yards. I am in an 8″ circle 99%, but I want to tighten it up and get to 8″ (vitals area) at 20 yards. Thanks again for the help. Be well.
