150 lb yew

<< < (4/9) > >>

adb:
A nice bow indeed. 1/2" of set at that draw is very impressive. It doesn't look like it's being drawn very far on the tiller stick, and why is it on a tiller stick anyway? At what draw is it making 150#? Also, what's up with the hemp wrap under the top(?) nock? Is there a flaw? Someone drawing this bow to 30-32" would be very nice to see.

I dont know english very good , so I dont know exactly what are you talking about. Near one of nocks was little cavity in sapwood , and wood loks a little to week for me.  by this draw weight I want to sure , that everything will be ok , so such reinforcement. Bow was tillered to 28" - 189 cm is full lengt but only 179 between nocks. On foto is pull on 25 " . I dont like make fotos with full draw such bows on tillering tree - before I make good foto - could be last about 30 seconds and it is to long for such bow in full draw - and nobody can pull this bow in my neighborhood. You say that near nocks should be round cross secion or all bow should have round section ?

Rod, if you make and post a 150+lbs yew selfbow with 1/2" of follow I'll promise to try and find good points :)

The fact that the bow is 75" long and only tillered to 28" makes a difference on the string follow here.  Tillering it to a longer draw length will add a fair bit of set

Henry: Having square edges on the back is not a good thing. 

P.S.  Nice bow by the way.  I know making a heavy draw weight bow is not an easy thing to do

Lukasz Nawalny:
ok , not good , but why ? I dont read book about bow making - in polish we have no such books and my english is not very good, so Im happy to know yours opinion. I have made few yew longbow with oval cross secion and in my opinion such secion make bow a little more string follow prone . Maybe in pacific yew with thin sapwood we have other situation?

A square edge on the back is much more likely to pull a splinter
