A buck that I harvested 5 years ago in Texas had a broken brow tine seen below. I never had it repaired.

Too cold to do much at 0ºF outside. Sounds like a great cold weather project for me to try. Maybe you have an antler that needs repair too.
Below, what the brow tine should look like.

I found a few YouTube’s to fix a broken antler with epoxy putty. You can look it up as well. You can use a taxidermist putty or wood repair putty. One fellow used polyurethane dark walnut stain once the putty was hard and dry. He wiped it on and off as needed to get the color correct.
Look for my article and how my repair comes out.
Soon…
