The left and right hand threads unscrew FORWARD which means counterclockwise for the left hand and clockwise for the right side. If you cannor loosen the BB and have stripped the grooves for the holder, get a pair of lock jaw pliers and lock them tightly to the BB that cannot be squashed with the bearing in place. Then get an 18 inch pile that will bit over the handle. That will free ANY aluminum on aluminum joint. Before sawing anything off you might as well throw the frame away. Andrew could probably save it but most shops wouldn't have the proper tools.
