I am finish welding the stringer brackets and wanted to dhow this little trick I stumbled upon to tack the rear stringer brackets in place. I pretty much used the stringers as a guide to tack the other brackets. Since the tail of the stringer falls naturally in the proper place on the diagonal tube, I thought why not use it as the holder while I tack it? I rotated the fuselage upside down and just had the rubber band holding pressure on it so it wouldn't want to move. It worked out beautifully...
