Title: Adding Second String Grove to Increase Weight?
Post by: tippit on September 14, 2016, 10:07:00 PM

Is there a way to predict how much increase in draw poundage you will get by shortening the limbs with additional string groves?

I have done a few, buy dont recommend it after tillering, because it will place extra stress on the limbs.  And if you re-tiller after piking the weight will only drop back down.
You can try 1/2" it would increase by 5# to 7#.

I think both Wood bows broke after piking...    :scared:

This would be on a glass bow and still within the tip over lay about a 1/4" on both ends...so 1/2" total.

1/2" total would get 2'to 3 pounds increase.
