I was working on an osage bow that had light splintery wood that wanted to crack when I bent in the recurves. One limb cracked twice, I filed off the cracked wood and glued on an underlay on to save project.
With deer season now over, I decided to work on the bow again. This time I am trying freehand bending using my vise, no form. This way I can bend just a little of the limb at a time, put the limb deeper into the vise and work down the limb as I go. I have the limb taper cut into the limbs so the bend is even.
Of course, there have been tip alignment issues that need to be tweaked back into line but that's no problem.
I use an aluminum reflector to speed up the limb heating.
Just starting out, this isn't one shot deal to get the amount of recurve I want in the limbs and to get them to match.
I added more recurve than I would have on my bending form and didn't get any cracking at the bends. I just took this picture; the other limb relaxed a little after it cooled off and will need one more bending session to match this one.
