That's a crazy amount of work and waste to cut a panel long ways unless they're 12' even still a one acre pen with panels you must be rich what's wrong with 5' no climb and t post? A small pen to pen break the hogs helps with escapees as well.
Ive wondered if you could just use no climb for a training pen. Do you have to bury the bottom in the dirt? how far apart do you but your t-posts? cant a big boar just work his way under? what do you mean by "pen break"?
