Slow motion videos of primitive archery

AWESOME!!! Thanks for posting and doing all the hard work for us Tuomo

I may be stating the obvious, but per the out of tiller vs good tiller vids and the limb timing myth, did anyone else notice that the out of tiller bow actually rotates during the loosing of the arrow??  There's actually quite a bit of it when you compare to a well-tillered bow in the other vids.  Not sure I see how that could cause the hand shock, but it may be it.

Wow! Lots to think about.  This is hurting my head  .  Thanks for the post.

K-hat - you are absolutely right! See this: http://www.youtube.com/watch?v=8pYVmrWzTP8 Same bow but tiller is much more unbalanced, plus there is 1500 grain weight in upper limb. The bow is rotating.

Hand shock is purely the residual energy, "waste" energy of bow limbs. Efficiency of the bow is depending quite many variable - limb mass, tip mass, etc. You can see how the bow is jumping forward.

How about a vid like the one where you let the bow fly forward, but with at arrow instead of dry fire.  I'd love to see the comparison w/ arrow vs w/o.  I know, easy to make the request lol

Another request   ... Would love to see comparison of long and short arrow paradox.  Short arrow being proper spine and cut to archers draw length.  Long arrow being a 3-4" longer than draw length but also with proper spine, so stiffer than short arrow.   

Great work.  I am still not sure which looks better for limbs the dacron or fast flight.

Same thing happens when you let the bow go with an arrow.  I was experimenting with a loose grip - a bit too loose.  Bow flew about 5 yards from me and stuck perfectly upright in the mud.  Was a little bit hilarious. It might fly a bit further on the dry fire.

I have been looking for this kind of stuff for a while. This is perfect! I just browsed your channel for about 5 minutes and have already learned a ton. I feel like this will greatly advance bow-building knowledge. Also seeing that arrow pass through that plum was pretty sweet!

thanks for the serendipitous experiment Bubbles!  That's what i figured, i was curious as to how much energy difference there was w/ vs w/o arrow.  I would have expected a bigger difference, however.   

[bubbles]

Yeah, I was surprised by how far it went. Maybe its a sign that my now isn't very efficient.

There is some new slow motion videos in my channel: http://www.youtube.com/channel/UCmVczwYUfq6sQQjCmKd2q5Q

Limb vibrations with different weight arrow, unbalanced tiller, etc. Just old stock, I had now time to upload those in Youtube. Now I don't have camera until April, and no new videos waiting. But I have ideas what I want to film and see, when I will hopefully get the camera again!

[Tuomo]

I have loaded the last 29 videos on Youtube. A lot of flying arrow and a few flying bows too...

If you have any questions, please ask!

Thanks !!!!

Great, now I need to purchase a high speed camera to see if my arrows are tuned properly.
