Wrapping a Bow Limb with Sinew

Sinew is a staple in any bowyer’s toolkit. Here I show how to make a quick patch in a weak area of a limb by wrapping it in sinew.

The sinew is shredded and soaked, and a light coat of glue is applied to the area around the weak spot. The strands of sinew are wrapped tightly around the limb, then smoothed over with more glue. It’s allowed to dry for at least a day – more if it’s humid.

Normally this fix is applied to cracks along a limb’s grain. This particular weak spot is caused by a compression fracture around a pin knot. I don’t yet know whether this will help the compression fracture, but it’s a quick enough fix that it’s worth a shot.
