ok..I am a first timer.. My mother has much experience with home remodeling, but is strangely unavailable (grin).... I would like to cut an archway double door into a load bearing wall....I am somewhat familiar with how to brace it... boards on their sides 3 together..but what size boards and how do I get them in?? What sort of tools do I use to make the hole?? What about electric lines etc?? Any information could be direct mailed to me at email@example.com Thanks so much!!
