Title: What does trapping the glass on the limbs mean? How to sharppen Grizzley broadheads?
Post by: buffalo53 on October 02, 2013, 12:33:00 PM

Hi   I saw a reference to the glass or veneers on a JD Berry bow as being trapped, what does that mean? Also, is there a sharpener that works well on Grizzley broadheads?  Thankyou George Hill

I think trapped refers to the limbs being trapezoid is shape. Wider in the front, narrower on the back.

Trapped can be from the belly side or back side.
It means that the glass has been removed at an angle. Leaving more of the core woods along the edge,showing.

On wood bows that are,backed,with bamboo this is sometime done so there is less bamboo so it doesn't over power the belly wood.

In glass bow there are different benefits and I don't feel qualified to respond.

Most folks use a file and stones on grizzlys but some of the scrapper type will work.

This video shows using a file.  I saw a recent post, and the KME broadhead sharpener was the favored method.

Trapping is one way of reducing the draw weight on  limbs that are a bit too heavy as well...a decision needs to be made on narrower belly or bac

Here is a JD Berry Taipan that illustrates "trapped" from the belly side quite nicely.  Smooooooth...

Great sharpening video also.

Hi  Thank you to all of the above posts. You can certainly count on fellow members to respond unselfishly with great information. To Chromebuck I have a Taipan, but I did not know that the bevel on limbs were called trapping. Thanks again George Hill

Buffalo:  If you cut a cross section of the limb, it would be trapezoid in shape.  Trapping is slang for shaping the limbs in a trapezoid shape. As others have pointed out, the wider limb may be the back or belly depending on the bowyer.
