Not sure if I've asked this already, but on smaller stands that won't be dealing with as much weight, would it be possible to use nails, for no other reason other than it would be kinda fun? I know screws hold things in place while nails are able to bend and handle shear, but stands don't really shift around like a house would, so again, for small tanks (my definition of small is a tank a single average person can carry without breaking it), would it be possible to build a stand with nails?
