Back To Inside Welding

Took the welder back inside again to do some more welding. Remember the slots I made a while back in the top of the sides?  This is why.

The middle weld is the the reason.  This weld joins the back of the D section on the outside to the top of the side panel and provides a hidden weld to make the bottom of the of the D section stable.  The other 2 welds are long tacks just to add more strength to the roof to side panels.
