i am working on a yew bow.and i measured 3 inches from the nock and tied a timber hitch for the first bracing.and then i measured from the back of the handle to the string and its 1 7/8. so,what do i need to do to get 3-4 brace height on the first bracing.maybe i should go back to long string tillering which is 10 inchs from the back of the handle area and take some more wood off.or is measuring 3 inches from the nock down not enough.just trying to learn to learn more about this.its the first i have gotten this far on bow making and seeing any bracing got me excited.thanks john
