Hi Everybody,
Allow me to introduce myself, my name is Robert, I live in northern california and I'm new here on primitive archer, but i've been building bows for about 2 years now. I'm glad that you were all interested in my video about the Klamath Style Yew Bow, it was a lot of fun to make. I appreciate all of the criticisms and compliments alike!
Firstly, I'd like to say that this video is not intended to be a How-To video, I don't think I'd be qualified to make such a video seeing as I'm only a beginner. It was however intended to be a small experimental archaeology piece; an attempt to mimic old Homer Coopers techniques as best as I am capable only for the sake of my own curiosity about native american composite bow construction.
I learned a great deal in making this bow, especially in regards to the properties of sinew, which I see has generated a bit of discussion here as well. In my opinion this is not the best method of sinewing a bow, for several reasons. I much prefer to lay wet sinew out on a board, comb it parallell and brush the glue onto it before applying it- like korean hornbowyers. It does appear to be accurate though, ethnographically speaking atleast. You can see sinews being applied with a small flat stick from seconds 23-33 at the beginning of the video.
I found this sinewing method very difficult to use because the dry sinews were still stiff and therefore very difficult to straighten or neaten. Furthermore, since they only absorbed the moisture from the glue, they did very little shrinking as the bow seasoned. This, I propose, explains why the Yurok felt it necessary to string the bows backward during the application if the sinew- the reflex had to be induced with the string rather than with the sinew drying. While it may not have been the optimal sinewing method, and my inexperience with this technique made it most unattractive, the backing was still very successful in my opinion. After seasoning the bow held 4.5 inches of reflex! After having shot around 200 arrows the bow has taken no set and has even retained reflex in the limbs. This is of course granted I've only taken it to a 19" so far where it pulls 40lbs.
Again thanks for watching, I hope you guys enjoyed the video.
Robert
