Archery

I want to build myself a spine tester to calculate the spine value of arrow shafts using the ASTM F2031 standard. I do know that I need a 880 gram weight and that I have to measure the amount of flex that the shaft produces when I hang said weight at the center of a 28 inch span off the shaft.

Well, but what then? I can measure the amount of deflection I have then but let's say the shaft is deflected by 1/12th of an inch or some millimetres. How do I calculate a spine value that ranges between 20 to 80 from that?

Can anybody give me a hint or solution?

I have a suggestion for a rule amendment. It goes like this:

When posting pictures of your targets, post as much info about your setup as reasonably possible, ie distance, target diameter, bow type etc. If you're looking for advice, be as specific about your gear as possible.

Reason for my suggestion is that a lot of the time posters will leave out this info, but still be looking for advice, or to show off I guess, when posting a picture of their target. I mean a spread of 50cm at 18m with a compound bow isn't that impressive - not that there's any reason to discourage the archer. But was that a 15cm spread instead, at 70m, with a bare bow, then that's pretty darn impressive.

I like to give constructive feedback, but I know next to nothing about anything but recurve target archery.

Back on December 24th, I wrote the mod of this community, !innkeeper@lemmy.world, suggesting this rule ammendment. It's been two and a half week and I haven't heard back. I also noticed when writing the mod, that the account haven't posted or commented anywhere in a year. So now I'm trying the community instead. I have no idea what we need to do to actually implement the rule, so I'd thought I'd give democracy a shot in the meantime.

Haven’t gone to the range in over a month, really thought I wouldn’t be able to pull my bow back, but I picked up rowing recently and it’s been a huge help in between archery sessions!

New Bow Day 💕

I got into archery cause my friend got my husband and all my other friends hooked. My friend and I happen to be the only lefties in our friend group. Last year, he got a new bow and generously gave me his Bear bow so I could give archery a try.

Starting out was pretty rough. My draw weight was 7-10# and it was hilarious attempting to aim at 45 yard targets. But I got really into it and this summer, I upgraded an Altus with 43# draw! Had to celebrate with a proper group pic at the range.

For anyone new to the hobby and not sure they can do it with their noodle arms, you absolutely can! Just gotta believe and crank that weight up slowly!

Hoyt Altus 42#

Hi all,****

** **

I am very excited, I just bought a new Hoyt Altus (weird name IMO but whatever) because my shoulders is not what they used to be, my old bow is getting to be a bit much for me. Also, I just felt like a new bow and the Altus is a beauty.****

** **

Anyway, on to my question: I've been shooting 340 spine carbon arrows out of a 1999 Hoyt Raider set to around 65#(Used the raider for some years, then stopped shooting for 10 years or so, started up again 4 months ago). The altus is pulling 42#. My draw length is 31", so I have LONG arrows. (76 cm or so) My question is: Can I continue using my current arrows? I guess they might be a bit stiff, but I ain't no Levi Morgan, if it hit somewhere in the red at 15m I am quite happy. (I am hoping this will improve with the lighter bow) The point is I don't care (yet) about perfect arrows, I want to shoot more so I can concentrate and work on my form and process with a bow I can handle better.****

** **

I guess I want to know if the new bow will fire the old stiffer arrows with reasonable accuracy without damaging the bow?****

** **

What spine would be correct for this bow at my draw length? My wife uses 400 spine on her 35 or so pound bow, but her DL is very short. On a long arrow, the 400 might be too floppy?****

Thanks!

But more inportantly, it was a nice round. I felt relaxed and it just felt good.

The rising star from Lancaster, Pennsylvania looks to become the first American to win Olympic gold in archery since 1996. She could become the first American woman to claim an individual medal since 1976, when Luann Ryon won gold in Montreal.
