Title: Hickory propeller?
Post by: TroutGuide on August 20, 2010, 11:17:00 AM
I have a roughted out hickory stave drying and it looks like a propeller.  How hard will this be to fix.  I plan on using the natural backing left from removing bark but could back with more hickory if needed.  I dont want to go too far if falure is eminent.  How do i go about fixing the twist?
Thanks, Brian

Probably not what you are looking for but I am doing an osage propeller but am doing a takedown.  So I have two halves that I can rotate inside the handle, slightly, so that limb tips are nearer to being on the same plane (no pun).  The result is that now the near handle wood is out-of-plane but the limbs pull evenly.
It is evident that the tips like this better during the tillering as the limbs want to rotate to keep the tips on the same plane.
I'm keeping the bow long for now so reduce stress.  Time will tell

a bit of prop twist wont hurt, as long as the string stays on and full draw is good. you could use heat to take some of it out, alot of guys use a pipewrench on the twisted limb with some weight hanging off it.

Made lots of  prop twists bows. No worries about to 35 degrees of twist. Be sire to look at tiller from both sides and take the average between the 2 picturesThere's info on my site. Jawge
