Brush buttons may be placed on each end of a recurve’s bowstring to prevent sticks and branches from getting caught between the tips and the string. Brush buttons may be purchased from most archery shops, but I prefer to make my own from wine bottle corks. Some of the new corks are not true cork at all, but rather a man-made substance that works rather well for brush buttons.
The cork is about 1 1/2″ long, and should be cut into three pieces measuring 1/2″ each. Drill a small hole, about 1/8″, through the center of each brush button. I rounded off one end with a disk sander. You will need two brush buttons, one for each end of the bowstring.
Run a hairpin or cotter pin through one of the string loops, then push the pin through the hole in the flat side of the brush button and slide it down the string a few inches. Repeat this step with the other loop. String the bow, and position both brush buttons so they just touch the limbs. Shoot a few arrows to make sure the brush buttons don’t affect your accuracy.
