I know this isn't really for bass, but at some point I would like to do this. I was gonna cut a piece of deer bone for a nut blank, but given the < -20 degree windchills, I'm not gonna dig through our yard yet. So I was gonna make a plastic blank to just get me by. I made a mold out of modeling clay shaped by a 1x6 lego brick, which is slightly larger than the nut on my Les Paul, and also larger than my bass nut. My mom like to make cards, so she has plenty of embossing powder in her craft room. Before I bother asking her for some, would it be hard enough to use? I was thinking of putting some powder in the mould and heating it with her heat gun. I was originally thinking of melting down water bottles in an old pan I found buried in our yard, as that plastic is quite hard even though it's thin. Ever tried drilling a hole in that stuff? But being that it has a melting point of about 500 degrees, that is quite inconvenient. Any thoughts? Oh, and the only reason I thought to use plastic to make a temporary (or permanent, depending on how well it turns out) nut is because two nights ago I dreamt that I was looking for spare bits of plastic to melt into a nut until I could get my hands on a bone. It's amazing the things you can come up while dreaming. I actually have a small bass riff written down somewhere out of a dream. If I can find it I'll post it for you six string players to test out. I would try it if I had a sixer, when you got a four banger, you can't do much.
