Yeah, the swamp has finally dried out and the little peepers are out of the trailer, out of their brooding boxes, and in the coop.  Without another moment wasted, the Planner was back at work on the subframes again. Two weeks have past since the outer frames were erected. Now for the inner frames and cross bracing.

Upon erection of the outer subframe, a mistake in the design was discovered. Unlike other measured errors, this was more than an inch. This error was the depth of the I-beam. One side of the cross bracing sits flush with the outside of the I-beam while the other sits inside the I-beam itself. In order to fix the mistake, the I-beam columns were boxed at the location where the cross brace intersected.

Some of these boxes were on bottom and easy to weld. Some were on top and harder to weld. 

However, as it turned out, the mistake was not a mistake at all.  It would have been difficult to weld the cross brace when mounted inside of the I-beam flanges.   Mistake or master planning?  Interesting….

Fortunately, once all the materials were cut and tacked into place, the welding of the boxes went fairly easy. Upon completion of the boxes, the cross beams were attached, tacked, checked for plumb and square, and welded together.

Three days later all inner and outer subframes were erected and welded in place.  Lots of work done in a short amount of time. Lots of weld rods were used in a short amount of time, too. It took just short of ten pound can of welding rods, the assistance of the Kid and the tractor, and ample supply of patience by the Planner when assisting the Kid in the making of his videos. 

The video shows two boxes being installed on one frame.  Both are on the bottom, one left and one right, but with different views. Being nine, a boy, using a phone with no stability supports, and not being able to watch clearly because he had welding hood that was too big in order to protect his eyes, I think he did a fairly fantastic job with his videos.
