February Antler Repair? I Ran Across A YouTube To Fix A Broken Antler Brow Tine
This is my first attempt at a brow tine repair. Came out ok. Need to paint/stain more but the JB Weld KwickWood® putty worked.
Note: I used my new GoPro Hero 13 Black to film and edit the above video.
Below is the right side brow tine fix. Not bad for my first try. I can play with paints and other stains but hey, it looks ok for me.

Practice on other antlers, can improve my skill. Need to buy paint/stain/urethane for correcting brow color if I want a pro job. But I am happy with it as it is for now. It was as a fun repair winter lesson.
