I just got back from a bow building course that took place in Inari, a small town situated in Northern Lapland (Finland). The course was held in Sámi oahpahusguovddáš, local Sámi educational center, and the teacher was archaeologist J-P Joona.
J-P has been one of the few people over here actively researching and building North-Eurasian laminated primitive bows. His emphasis during the course were bows traditional for our own area, ie. present day Finland, Sweden, Norway, and adjacent areas of present day Russia. The course was a great success, and hopefully there will be similar opportunities in the future. Also, as the ´scene´ for this type of bows develops and matures in Finland, perhaps there will be more courses, competitions etc.
Most weapons built during the course were strictly based on archaeological & historical models originating from the area I mentioned above. For this reason the materials were limited to reaction wood pine for the belly and birch for the back. Possible siyahs were also birch. Modern glue however was used for laminating the bows, while fish glue would have been traditional. Strings at this point were modern as well. All the bows were wrapped in birch bark. Heat bending was allowed, and it seemed like a must for certain models, esp. ones involving back pieces extending from nock to nock.
Bows built during the course will be presented in Siida, Sámi Museum in Inari. For this reason finishing touches for the bows will be important. Below you can see my own example, still lacking bark at this point. It pulls 51# @ 27" ...good for hunting.
Hopefully more pics to follow after wrapping etc.
