I just finished enough of the welding to give this thing a try. I’m lifting some small butternut logs that are a foot or so in diameter. I designed the size of the arch for lifting much larger logs. The arch is made from 3″x2″x1/4″ tubing. The winch is a 12000lbs Harbor Freight winch mounted to the front of the trailer on 4″ 5.4lb C channel.
