Title: layout question: knot or twist?
Post by: jeffp51 on March 10, 2015, 01:15:16 am
How would you lay out this stave?  If I start all the way at one end, I would place the knot pictured in the final 10 inches of one limb--but have to deal with the reflex and 45+ degrees of twist at the end.

On the other hand, if I cut the stave below the reflex, I have a relatively straight stave with a knot about 10 inches from the handle section.

On the other other hand, I could cut off the final 6 inches or so, use the natural reflex as the recurve in one limb and bend the other to match, and have a knot right about mid-limb, and an the need to remove some twist.

The wood is elm, by the way.  Please share your opinions.

Don't know the length, but leave it long and heat straighten.  That knot 10 inches from the tip is less of a concern than 10 inches from the handle.

  I cut that stwist off the knots not a problem.

  Unless you have a problem makeing shorted bows.
  That stwist will come out in elm. Use dry heat. But go slowwwwwwww bending and tillering so you won't get checks.

If you cut off the twist how long will the stave be? Jawge

Now I have two opposing opinions--both of which I have thought at one time or another.    Anyone else care to chime in? If I cut off the twist, I can still get 70 inches if I wanted.  I was aiming for about 66-68 with a stiff handle.

No one right answer. If it were me, I would want the knot where it would be under the least stress and less likely to cause problems. Closer to the tip will do that. 70 inches is a lot to work with, so cutting the twist off is an option, but you just need to consider where it places the knot if you do so. Every move is a trade off in some way.

Can't tell for sure but it looks like you have a knot on the edge near the twist. I would be worried about a knot on the edge than the middle. Like I Said I Could Be Seeing it Wrong though.

There is a knot there too, but between thinning and narrowing, I am pretty sure that one will be gone before I am done.  For what it is worth, I have 58 inches shy of the big knot--I could also do a short bendy handle bow and avoid the knot altogether--but I would have to deal with the twist and bend.

As long as you leave the area around the knot a little wider the knot shouldn't be a issue. Imo  I'm still a newb  but that's my take on it

George, what do you think?  I have gone back and forth several times in the last couple of days.  What is the best place in a limb for a knot like this?  I am nervous because my last stave with a knot blew up in spectacular fashion.
