Brace Height Affect on Bow Poundage
Вставка

- In this episode I’m tackling the question of what happens to bow tip to tip length and, more importantly, bow poundage when raising or lowering brace height.
EDIT: I mention when doing the 7.5 inch brace height that the initial poundage reading was 43 pounds. This is not true. That was a false reading and I didn’t explain that very well in the video. At 7.5 inch brace, the poundage was averaging between 41 1/2 to 42 pounds. Just want to make that clear.

I shoot a Hoyt Satori with 65lb Black wolf limbs of a nap center rest. I had a bunch of 400 spine Easton axis trads from another setup. The issue I had was that the bare shafts were shooting stiff. My BH was at 7 I raised my BH to 8.5 and the bare shafts started flying straight. Great vid brother.
I always thought you lost speed on a recurve when you increased brace height. I am glad you did the heavy lifting on this one, thanks. ✌
That's correct lower brace height gives the bow a longer power stroke hence slightly faster arrow also weakens spine higher brace height will stiffen spine and give you slightly less speed you can see what brace height does to a arrow with any super slow motion video on a decent phone if I don't to build out the strike plate to make arrow stiffer I'll either raise brace height or move string silencers closer to the center of the bow which will also stiffen the spine opposite will weaken
Verry well explained, nice video! Brace is verry important, makes a world of difference! Stay healty.
If your arrow showed a little weak raise your brace distance and it will correct It. In essence it is placing less energy on the arrow this stiffing your arrow. I just did this with a new bow and it worked. One thing that is unarguable is facts
The only way you're getting different weights and overall length is if you aren't drawing to the same distance. I've seen this test done several times with actual draw boards. And they don't reflect your results.
The only poundage your changing is the weight of the first inch of draw.
And shortening the power stroke.
This changes the energy into the arrow,but a bow that draws to 45@28 with a 7 in brace is still going to be 45@28 with and 8.5 BH
Put a bow on a draw board. Set brace height at say, 7”. Measure the tip to tip distance at 28” draw.
Now reset brace to 8” and repeat the experiment. Measure tip to tip distance at 28” draw. The limb tips will be closer together with an 8” brace vs. a 7” brace because with a 8” brace, the string is shorter, making the limb tips shorter distance. If the limbs tips are closer together, that means the limbs are flexed/bent more. More bent limb means more poundage.
I owned a bear recurve when I was 15. Shot it for years. Loved that bow.
excellent video, thanks!
Good job , Great information !!!!
Is this a murder basement?
I'm getting murder basement vibes with the background. 🤔
I do not understand why some traditional archers do not already know this, or at least have not realized it yet. Good video !
Nice video...I do believe that the arrow will have more momentum if the nock has longer contact time before it leaves the string... just IME perceptually, I don't have scientific data to back it up. I really like the breakdown here ... Gets me thinking.
Billythebassist stay tuned for Part 2!
Very interesting. I got that concept wrong all the time
Excellent video!
Good explanation
Very informative.
Hey, what is that bow you held up at the start of the video? Is that an old Kodiak Hunter???
Not sure which one you’re referring to. At the time I had a Grizzly and a Kodiak Magnum
It was the Grizzly, which has a handle riser shaped like the Kodiak Hunters, with a distinct deflex. I thought Grizzly bows always had a continuous curve and uninterrupted fibreglass on the back of the bow through the handle riser like the current models - I have never seen one like yours before, but I may have missed a running change in the model specs.
@@seayak the 64-67 (maybe 68 too) bows all had that look. After that they got rounded
@@bowhuntingsoul2149 Hey, great, thanks! That explains what I was seeing, and is something I did not know about Bear bows of that vintage.. They retained that deflex riser configuration for the Kodiak Hunter after that date (I had one of those which I bought around 1973), which is what was confusing me.
Bear Archery bows, the vintage ones, have good medicine. I wish I still had my Bear "Whitetail" 45/50@27"/28"
Did you change the stock string on your grizzly?
Mtb Joshua nope. Not sure how old the string is but I bought it used with the bow severs years ago.
Too slow- u need to get to the point faster- instead of talking about what ya gonna do- you gotta do em. And fast.
