Does anyone know the breakaway force for a safe halter?
I repair and make my own halters for our two quarter horses and I repair halters for others at our barn. Now I have made breakawy fuses (using chicago screws) and leather crowns that can break away. Also I have altered lots of nylon webbing halters to break away. But I have one concern. Different weight leathers (and quality) and manufacturating techniques can result in break away halters that separate at a wide variety of forces. Also the same fuse that would be safe for a large horse would not be safe for a pony.
So at what force should a halter break away for each bred?
If I can get a idea ... lets say 100 lbs or so for a quater horse (the average lanyard that people wear breaks away at 20 lbs) then I can calibrate the breakaway bits for a halter accordingly and be confident that I have made a safe and useful bit of tack.
