I have a question about beams, I have a beam in the basement that needs to be replaced. the current beam is 6"x6" I am considering using 3 or 4 2"x12" #2 Douglas fir boards to build the replacement beam. The new beam would end up being 4.5"x11.5". If my research is correct on this the new beam will end up much stronger then the older one, do you agree? 2nd question would it be best to nail the three boards together or use bolts?
Thanks in advance for your help.
