Title: Moistre effects on hickory bow
Post by: LaBill67 on May 30, 2017, 07:01:08 am

I have a recently completed hickory backed hickory bow that tillered out very nicely. After sometime I noticed the tiller changed. I am wondering if that change is due to high levels of humidity in the shop where it was stored?  Also how should I treat it? Should I bring it inside for a while to dry out and then retiller? Any suggestions would be appreciated.

It could be moisture. My bow for the year is in AC.
Tiller changes could also happen from not exercising the bow between wood removal sessions.
I remove small amounts of wood even to the point of counting the passes and then exercising the stave at short draw 20 times or s.

Hickory changes dramatically in the humidity losing draw weight.  I've had bows fluctuate 10 lbs, or so.  When you say tiller change is this what you refer to or is the actual tiller not right?  Haven't noticed that.

   I discovered a problem several years ago with the way i stored bows in a drum. The bottom limbs took on more moisture. The drum was crowded with bows and the air circulation just wasn't sufficient to equalize with the top.

Thanks everyone for your inputs.  I'll try to get a photo uploaded.

Warm the bow with a heat gun and see if it comes back in.
