Twist in limbs

[Garman]

Hello friends, new to post. I am just finishing my first bow. It is a laminate long bow hickory bamboo backed. Coming in around 44lbs @28 right now. I am just finishing tillering. I have an upper and lower limb twist. I am asking for best suggestions for how to proceed. If it is too much material on on side or another what should I do. If not what should I do? Thanks guys. This is exciting to me, been shooting compounds  for 30+ years. Decided I needed a hobby.

Welcome to TG.
This picture below will help.

Thank you very much, this gives me a good point

Sure thing.

The string will always drift towards the weaker side of the limb.

SO you need to remove wood from the side the string is drifting away from.

Also check the depth of your string grooves at the limb tips, the picture shows that also.

Started to get some of it out. Need to get a bit more. Shoots ok for a training wheel shooter

Work on the worst limb twist first.

Working on that limb can also help alleviate the twist for the other limb.

But not always...

Just have fun....

Below is a link to a useful tillering tool..

   Something else you should check... It's the first thing I check if I have any kind of twist...   Make sure your limbs are coming straight off the riser...  Just because you put lines on your limbs and sanded up to them does not mean that they are perfectly inline with your riser...  If they are not straight off the riser and you go sanding to correct twist, That would be two wrongs trying to make a right...

Don’t shoot it anymore until you get the limbs straightened out.  No sense in training the wood to bend the wrong way.

Also, make sure limb removal is the same on both sids of the limb.
At any rate, remove wood from the string side which is the side NOT bending enough.

well I got most of the twist out and finished. This is my first bow using no plans just off the top of my head putting it together and piecing together info. before I found this website. Anyway, I will explain some that happened. When buying materials I decided to go with a hickory with bamboo backed. When I bought the bamboo I never gave it any thought and glued it up before measuring widths and such. So I got a piece of unplaned bamboo very uneven in Thickness. Anyway it became a point in tillering and getting the twist out that I would have had no more hickory to work with. I got most of the twist out and tillered fairly well and racked it up to experience. It shoots fairly well so far at close distances ( have not tried further out yet) and I understand these issues will continue to make the bow struggle with accuracy and longevity of the bow itself. But to be honest this gives me the confidence to start on a new bow these mistakes I have learned there is no doubt the next bow will come out good. This was my form of a test bow. It has also renewed a interest in shooting traditional bows. I appreciate all the feedback.
