is the nature of the beast realy as your weld cools past its melting point it shrinks.
when i did my br's i tacked the bottom corners next to the wood all clamped down first then tacked the top corners, welded the sides of all tubes doing the same side one left one right, then the tops as sides put in my uprights corner tacked then tr's,d's and so on when i fliped it over to do the bottoms of the br's poped it back down after flating off and i had 1-2mm of gap if the back was clamped down after fully welding. i think was pritty good realy i was expecting more
