Calculate draw weight?

<< < (3/3)

Aksel:
Thanks for all interesting ways of calculate the draw weight. It turned out to be apr. #83 at 27" so #2 per inch was right in this case.

willie, I am not a specialist in arrows but my understanding is they all shot looong arrows which makes it difficult to say anything about draw length or shooting style.

Original bow was a very narrow and thick elm bow with shoulders/ levers half way out the limb and only 3,6 cm / 1,4" wide. 61,5" long. I stretched the length by 10% otherwise faithful to the measurements. Grip area is short, a little narrowed and barely thickened so it is not stiff.

This is the FD at 27" profile i came to after I evened out the tiller the original measurements gave me. Any thoughts or comments appreciated!

willie:
Unusual design for a bow,

I am curious if the find you are replicating has been dated?  If old enough could the design be considered a transition between the age of the atlatl and the age of the bow? you mentioned longer arrows associated either the find or era.
 I can see where more "atlatl like" darts would work better for such a bow than shorter "arrows".

Aksel:
Hi Willie, yes the bows for this site (Tybrind Vig, Denmark) is dated to 4-5000 BC, so it´s later part of the early stone age -but still 3000 years younger than the famous bows from Holmegård. Not many intact arrows exist from mesolithic times, but the ones I´ve read about are 90-120 cm (3-4 feet) long, long by today´s standard but quite typical for primitive archery. With some exceptions are bows from that time typically 150-165 cm long. Mean height for mesolithic european men were 166cm (65"). Bow design is a lever tipped bow with bendy handle :)
