Title: surprising scyth
Post by: Lukasz Nawalny on October 26, 2013, 04:45:01 am

Some time ago I have made few scythian bows in this design http://www.fotosik.pl/u/robbin/zdjecie/1/album/1119559 . All hickory selfbow with sinew , glued only in handle. I was not very glad with work, stacking on 27 " . Now I make more reflex on this first bending, give more comfortable draw. In last week I make chrono test and this bow shoot 198 fps at 27" with 7 gpp arrow and only 42 lb. I was suprised, I dont expect good results with so deflexive design. Wood and bows will always suprise me :)

Deflex allows the wood to stay fresh. Fresh wood is very important to speed.

That bow is amazing!!! I have been trying to make one similar for years. Can't seem to make it work. Can you give us more details, dimensions? Thanks!

That is an amazing bow- especially without horn on the belly!    Very good work!

sinew thickness is uneven, most is concentrated in this small deflexive areas, protect wood.

Thanks for sharing Lukasz. How much sinew did you use?

Those are impressive statistics Lukasz. The level of refinement you put into your bows is amazing.

thanks, Im happy that you like it. Sinew 3-4 mm on deflex bending 1-2 mm on limb and working recurve. Now I make on scythian little differend type of work. Last 10 cm on recurve is static , more reflex on this bending near handle and more work in middle part of limbs. This solution give good performance and more smooth draw. Good sinewing and good wood give very nice results. Like in this bow, I was very surprise http://www.primitivearcher.com/smf/index.php/topic,42590.0.html

Deflex allows the wood to stay fresh. Fresh wood is very important to speed.

The trouble with that thought regarding this bow is that the "deflex" is more of a decurve achieved by compressing the wood to attain that curve.
 Is the wood still "fresh" if it is boiled to plasticize it and then compressed?
