We're making a wall for conventions. Some problems we've found is wood splitting so well grabbed extra brackets to keep it together.
The assembly is 4 12ft wood beam cut into 8 ft and 4ft beams. We then cut the 4 ft beam to 45 inches and use a bracket to keep the two beams together. We added hinges to make storage and transport easier. We noticed a problem with the hinges not sitting flush. So we got a dremel and made an indent for the hinges to sit flush.
