Hi folks! I recently took in an already finished osage bow which has an extreme propeller twist. I have removed the finish down to bare wood. I am just not sure if the tips can be bent on a caul and straightened. Has anyone had any experience with this? I can add pics later.

Both limbs have approx. the same twist

This is cake, par for the course with selfbows. It's super common to have a stave with propeller twist. Osage is relatively easy to heat bend actually. You can straighten that out in no time.
Read this thread.

Hopefully others will chime in. I'm on iPad so I don't wanna write an essay right now.

Over bend it about 15-20 degrees and you will have a flat bow when your done. Often times I vice the bow up, heat up said area, slap a crescent wrench/padding on said area for torque purposes, then hang a weight off the wrench handle to off set the twist. Let it cool a few hours and move along. Happens on nearly every wood and every bow. In some shape or form.

How does the bow look braced? You might not need to eliminate the twist. Wood bows can handle a bit of twist without adversely affecting the way it shoots.

Just forget it. It doesn't matter one jot. The only consideration is that the string lies in the nocks correctly.
