Maybe you remember this stave:
I have cut it last spring, just when winter has gone, look at: harvesting wood
In the meantime it has become a maruki- style bow, a yumi made of a single piece of wood, the fore- runner of the delicious to do yumi made of bamboo. It measures 75″ in length, 11/4″ in width at its widest point at the handle.
There are still some details to work, tillering it at 30″, about 55lbs, sanding, polishing, coating with walnut- oil.
The recurves are steam- bent, the s-shaped natural growing was at first heat- treated, but without any appreciable succes, so steam bending was required. The bow insisted on keeping a bit of its natural shape, I agreed, the string is running across the handle. Juniper is quite delicious to heat- treat or to steam bend, cause of its content of essential oils. The workshop smells great when working juniper. Store the splinters as a remedy against clothes moths.
The ratio of the length of the upper limb to the length of the lower limb is 1.61- the Golden Ratio.
The string is made of linen, the slight recurves are wrapped with thin buckskin, the handle is wrapped with a thicker buckskin, buckskin is naturally tanned with fat.
Eventhough I prefer short bows, I like this style of “primitive” yumi, due to its asymmetry it makes you feel to shoot a somewhat shorter bow than it really is. For to use it to full capacity, I guess I´ve to take some kyudo lessons.
This bow makes me feel very happy: juniper is one of my favourite plants, but I´ve never succeded in making a juniper- selfbow, they´ve all broken. I succeded in making shorter bows of juniper by backing them with sinew, juniper is very compression strong but tension weak. But this stave is completely knot- free with very thin growthrings- perfect. Done as long selfbow, it is a durable character bow.
