Title: How do I deal with a "roller coaster" stave?
Post by: Gwynnin on July 04, 2014, 09:11:39 pm
Making a light warbow (aiming for 85# at 34"). Right now it's 60# at 20". 78" long. Reflexed ~2" with 2 major waves in the upper limb.

I'm taking a pause on this one while my belongings make their way across the country to my new home. Also, till I figure out how to get a bow heavier than I can draw tillered. I'm used to dealing with character staves, just usually more, smaller issues.
Thanks!

Remind me of "Dogleg" one I did a while.
There are two approaches.
1. Use heat or steam to straighten it out a bit to get the limbs more symmetrical, which will make tillering much easier.
2. Leave it and allow the waggles to show up even at full draw. This is tricky and sometimes a heavy line drawn as straight as possible along the edge of the limb can help you see the true curve.
This post from my blog shows what I mean:-

This post shows the finished bow at full draw  :)

Don't you have some sort of tiller rig with a pulley? I shoot video using a camera mounted on the wall opposite, while I flex the bow on the tiller by heaving on the rope. Loads of pics on my blog, BTW the search enging on the blog actually works quite well.
