asking the wood to draw that far will reduce your chance of success,,
here are some things you might consider,,
draw the bow to 24 inches,, or sinew back it for the longer draw,,
not sure why you need to draw to 26,, but you will find if you mark your arrow at 24 and shoot it for a week,, 24 inches will be quite accurate for you,,
ok maybe the bow is for a friend that has 26 inch draw,, that may not be the right stave for that project,,
sometimes people think they have only one draw that works for them,, well making bows for alot of different people and also my interest in Native style bows has taught me that I can shoot about any draw length with a little practice,,and I think most archers could as well,, so let the stave dictate the best draw for that bow that will keep it healthy,,
I have been reading Laubin, ,and took note that the Sioux preferred a 23 inch arrow,, just thought I would mention that,,
