Day 113- Crush wall progress

Welcome back Ghouls! Looks like we're actually going to pull this off! It turns out the main problem was in fact the unbalanced nature of the whole block/ wall connection. In other words, we had the bracket to the wall placed BEHIND the bracket to the wheel on the I beam (see image from 'Day 117' post). This caused the front of the 2x4 block (labelled 'B' in today's images) to want to tilt upward against the I beam and jam up the sliding motion. I suppose we could have designed that a little better, but there is always a solution to every problem! So what we did was to use a few of the scrap 2x2's we have lying around from cutting down the longer pieces and screwed those into the front of the block and anchored them into the wall frame to pull the front of the block down. This opened up the space between the block 'B' and the I beam shown by the arrow and basically solved the problem! The wall is now quite easy to move! However to get it move uniformly is the next task. Now the other important improvement from the additional 2x2 brackets was that the wall no longer swings through the metal wall bracket labelled 'M'. This would have certainly produced metal fatigue failure right there and would have led to disaster, even though the weight of the wall is not too bad. You can see the basic 2x2 wall frame in the other image to which we will attach the vacuform panels. Now those dollar and change 2x2's are not all straight, so when I first tried a basic box type frame with a longer horizontal piece first on the bottom it totally distorted the frame and screwed up the sliding block alignment. That's why you see the shorter segments in between the long vertical ones. By first aligning adjacent vertical ones with the shorter horizontal ones, I was able to straighten the wall out first before putting the longer 2x2 on the bottom.
