Uneven Limb return question
« on: February 01, 2010, 02:32:50 pm »
Hey everyone,

I was recording myself shooting yesterday and when I was watching the video I noticed something funny on my bow when the arrow is released.  I slowed the video down to 10% of the original speed and I noticed my bottom limb returns waaay faster than my top limb.  The bow is the hickory backed hickory bow I made a while back.  The limbs are both the same length but the arrow pass is around 1.5 inches above center.  The tiller on this bow is very even in my opinion so could the height of the arrow pass cause the bottom limb to return sooner than the top or is this just normal?  ???  Like i said before I didn't even notice it until I watched at low speed.   I wish I had a way to post it but I can only play it back at low speed not save it in low speed.  Thanks for looking  any opinions on this will be very helpful...  :)  -josh

Does the bow have hand shock?  I suspect a lot of bows are like yours. They're just not filmed and viewed at low speed. Try moving your knock point and film it again. Maybe try three under or something as well to get an idea what it will take to get the limbs to return at the same time.

really not much noticeable hand shock to me... I really haven't ever shot a bow besides the ones I make so I wouldn't know any different I guess...  :)  -josh

The lower limb is often shorter than the top, shorter generally means faster...
Maybe tie a small anvil to the lower limb...that'd slow it down a tad :o.

I dont think that it would mean a whole lot.  If the tiller is good and it shoots good I dont think I would worry about it.  THe arrow is already gone by the time the limbs return.  May just be your form like Jesse said.

thanks Tell.   it is really cool watching the video on really low speed cause the string is just a few inches from my cheek the arrow is already 2 feet in front of the bow.  I had no idea about the arrow being that far ahead of the bow on release till now.   :)  -josh

When you draw and release is she rocking in your hand or is the handle pressure even? Jawge

i really wish I wouldn't've made the video now just wanted to check my form and followthrugh on my shots... Nothing really feels off with the bow, just surprised me to see the bottom limb coming back so much faster than the top limb...   :)

Could it be possible that the image on each frame of the video is affected by the way it is scanned into the camera?  I have seen this with still cameras where it scans from top to bottom and makes it look like one limb is ahead of the other.

Yeah it could be an effect of the video and the frame rate that the camera records at.  I've seen some pretty crazy things that a video can do.

Turn the camera upside down and try again?
