Well this bow is a few firsts for me. This 62" Osage holds 1/1/2" of unbraced reflex, it pulls 50# at 27". This was my first attempt at heat treating, and it improved the performance greatly. This 50#er shoots almost as fast as my 60# Osage recurve. This was also my first asymmetrical design, the top limb is 1/1/2 longer than the bottom, as described in Hunting the Osage Bow. I think i butchered the tiller, but i didn't want to drop the poundage anymore than i already had, I will know better what to expect the next time I try for a bow of this style. Any tips on tillering asymmetrical limbs would be great ;D Ty

Looks ok to me, my tip would be dont make your limbs asymetrical......lol.
-
Does that bow have a sapwood back?
-
No, It is just low density heart wood, The reds spots are reel wild, they give it a nice leapord look 8). And curiosity lead me in making the limbs of dif length, Torges ideas sounded reasonable enough.. ;D Ty
-
don't want to sound too critical, but i seem to detect a stiff area about lower mid-limb on your left (lower?) limb. on the right, the mid limb could bend a little more. the tip on the left limb seems to travel a little further (but might be the angle of the picture), which should give you a little room to bring the bend out towards the tip on the right, while weakening it to match the left. but since i'm a newbee, take my words with a grain of salt and listen to the more experienced bowyers on this board (like ryan) ;D
-
Like ryano said make the limbs the same and some larger pictures would help,
my eyes ain't as good as they usta be. Other than it looks pretty good
-
maybe this picture explains better what i mean:

Per Marius example, might be bending a little much on the lower limb just out of the fades?
-
Ya i knew it was off, but i really wanted to keep this bow shootable, and not drop it to far below weight. i will take some more time on the next one before i heat treat. ty
-
I'd go for broke and gently remove a little of the right belly wood. Might not take too much to even up the limbs. My view is that a bow that is a little under weight but is well-tillered is the goal.
-
Dusty bear, how do you make those ovals on the pics if you don,t mind?
Looks okay and sometimes your better off to leave well enough alone! I would shoot it and start another one. ;D
-
it's quite simple: open the picture in MS paint (it's part of windows) and select the ellipse tool. i start in the upper left corner at the same hight with the handle and somewhere above the left tip. just play around with it, you'll see how easy it is.
-
Thanks Dusty Bear I'll give it a try ;D
-
since i have already heat treated the belly, wouldnt removing belly wood have an adverse affect on the heat treated wood?
-
well, you could always heat treat it again. plus, less draw weight with better tiller doesn't automatically mean a loss of arrowspeed.
-
Nice looking bow. If you have a finish on it then I would leave it alone
