Time to start on the gates. This tailer has 2. As you can see I measure diagonally. I'm only doing this to be close. As soon as I have it into a "rough" rectangle I put it on the bench. My "bench is the back of the trailer. Makes a nice work hight. I've only solidly tack welded it at this point.
Because the gate frame wasn't quite true, I use a long bar clamp to bring it into shape. I would rather do this on the "table", thats why I only get it roughly square on the floor.
This trailer gate will have to hold the weight of a compact tractor. I don't know what they weigh, so I used 1/8" wall 1 1/2" x 1 1/2" tube. better to be safe than sorry. As much as I enjoy building the trailers, I don't want to ever work on them again.
I try to leave a bit of the joints unwelded, again, a place for the water to drain out.
The last pic is just showing the mesh. I ordered it a bit long. Its easy to cut down to size with the plasma cutter. I did this for years using thin wheels on the grinder. I do love using the Pcuter.
The side gate is going to be used to load quads. I used 14 gauge tube for that. The side gate is close to the same dimensions, but at least 30 lbs. lighter.
