When you are narrowing limbs what kind of a cross section would you stop at, square, elb 5/8? This is a generic question but I'm thinking of more toward the outer limbs and tips.
-
In the outer 8" or so I usually end up with an elb type cross section rounded belly.
-
Same as Badger.
Even at its widest though, my whole bow belly is radiused, corners rounded, and then that ellipse cross section gets narrower and more rounded or elb-ish if you will as it nears the tips.
I don't stop if I can still see flats or corners anywhere. Actually, I usually lose those shapes about halfway through tillering.
-
Me too, very narrow round belly tips with a more depth.
-
When building statics, I like to keep the back narrow and my belly flat and wide (trapezoidal cross section), and/or groove the belly so that the string has good surface contact to rest on. Seems to help with string alignment for me.
-
I think it was Paul Klopsteg or Clarence Hickman who first warned against making the tips narrower than their depth. The tips are apt to warp off sideways in that configuration. I only tried it once, but the tips did take some sideways set.
-
I figured that narrower than deep would be risky but I thought maybe square would be the saw off point but i'm happy with about 5/8. It would be a safety factor against twisting. I guess recurves are even more sensitive to this than a straight bow?

I haven't thought about that. I just let it flow. :) Jawge
