Looks like this bug was still having it's effects. My brain was off in never never land when I ground the bending slot on the wrong side of the bottom triangular piece.
Below, not a problem I had intended to weld over the slots anyway.
Wood moves when it drys, and metal moves when you weld it. Before clamping up the ribs and base plate, I retracted the A frame jack and then placed a 200 lb. piece of rail on the front to weigh it down I then raised the two front frame jacks and leveled the frame. Only then did I place the ribs and base plate and clamped them tightly in place. Ready to weld. This is done to compensate for the inevitable up tilt to the A frame when the welding is done.
After the welding was done, I removed the weight and cleaned up the welds.
There are a few more welds to do when I tilt the trailer on its sides, but otherwise I am ready to start on the hoist. It will be placed in the center of the base plate where I placed the white dot.
Maybe there is something to be said about the old saying that you have to sweat out a bug. I feel better after a good sweat, than I did when I started. If the energy is there, I'll get started on the hoist this evening after it cools down a bit.
