OK - to make a long story even longer - I acquired a self catching headgate in good condition that I would love to get in working order. The problem is I only have the headgate and am not going to spend a ton of money on a chute or alleyway. I know some of you guys out there have built your own chutes and attached a headgate at the end of some 6x6's or something. The cross bars on my self catching headgate are square not round. I am trying to figure out how I could mount it to an alleyway/chute on the end of some 6x6's with the structural support that I would need. It does have holes on the top/end of the cross bars at the top and bottom of the headgate. It has a stamp on it of Plains Mfg - Sydney Nebraska - bit nothing to be found on the web. So any ideas or pictures of what you guys would be great to get me thinking. Thanks for the input.
