From the quote in the OP: “I can’t really see saving the crib as a huge deal, unless someone built it by hand–which probably isn’t legal.” As worded, it suggests that building the crib might be illegal.
Logical question from this, the heart of the OP: “It’s not really illegal to make a crib, is it?..If such a law does exist, what other items of furniture are illegal to build at home?” One would naturally assume that along with building the item, one would possess it and use it. However, nothing has been said or implied about selling it.
From ftg: “Note the word ‘probably’”, as in ‘the chances of someone’s homemade crib meeting Federal Standards are nearly zilch.’" Along with the rest of ftg’s post, this clarifies where a concern of legality would apply. However, again nothing has been said or implied about selling anything.
Bryan Ekers & Gary T raise the question of how federal standards, or any law, would apply to the building and personal use of a crib, which is implicit from the OP. ftg, if this represents a misunderstanding of your post, kindly clarify what you meant.
tailake links to the actual federal standards. However, these are in the Code of Federal Regulations, Title 16 (Commercial Practices), CHAPTER II (CONSUMER PRODUCT SAFETY COMMISSION). These clearly apply to selling (commercial use) such a crib as a consumer product. These do not clearly apply to building and personal use of the crib, which is the question from the OP.
I maintain that one is at liberty to build, possess, and use a crib, and that such building, possessing, and using, IN AND OF THEMSELVES, are not violations of law. I would be happy to be corrected. I have seen nothing in this thread or its links so far, however, that would contradict my contention.
