Well, I did state "typically." It's been several years since I framed houses.
Yep. It mostly depends on the dimension of the lumber, the span, and for vaulted ceilings/roofs, the pitch and local codes for snow loads and such.
Perhaps, but not for the framing crew that I worked with during my late-teens and early-twenties. Studs, joists and rafters were always placed within 1/2" of specification and walls were ensured to be "square" to within 1/4" diagonal to diagonal. Perhaps "they don't build them like they used to." But, most of the houses that I helped to construct are high-end "spec" houses.
When did you post: "Not "everything" is placed on 16" centers. You might consider refraining from making comment on subjects about which you are ignorant?"
bloggs enjoys permanent residence in my kill file. I trimmed my previous reply only because it is directed to bloggs. I may have "replied" to your post, but my previous response is directed only to bloggs, not you.
