I was thinking about this today, and wondered, why don't they use glass as a nut material? I mean, it's a very hard and dense material, resonates very well, does not wear, and can be extremely smooth, not to mention kinda cool looken.

So, anybody ever heard of a glass nut, or do you think it would even work well?

I imagine the strings would cut it up.

Its quite brittle, would be a lot harder to make than a bone nut, can have very sharp points.
Not really worth it just for a nut. Plus you can't really file glass, it just cracks and chips out.
#4
Depending on the kind of glass, it could shatter rather easily. It'd be under a ****ton of tension too, so something that produces very sharp shards exploding at high tension...

no it wouldn't. I think a glass nut would work provided you could manufacture it well. Which would be extremely difficult, especially if you were gonna try and do it at home or something.

Glass would probably work provided you could make it into a nut. I recon plexiglass would work well too, it's easier to make and people already use it in guitar bodies.

The kinda glass I'm talking about is like coke bottle glass, and it doesn't really have sharp edges unless you break it, I've seen glass eroded by water to the point where it's silk smooth.

Plexi glass wont work cause it's soft, it's not really a glass material, and you can wear it and damage it quickly.

I know the nut slot would have to be perfectly flat in order to not crack the glass nut, but the slots could be eched in with a dremel or something and polished into a smooth finish. Glass is very easy to work with when you get it hot.

I'm just thinking glass would work great because it is practically a frictionless surface when met with a round piece of metal.
#9
Lexan (polycarbonate) would probably work. I suggested plexi because it's harder than the plastics people currently use as a nut and transparent. I recon if you could make a glass nut while it's still hot with slots and everything and minimise any cutting or carving, that would make it less brittle and it could work fine.

Guitar strings aren't round they are covered in a shitload of little grooves.

Yes, but everything is round, there's a reason why they call them round wound strings, they can have a hex or round shaped core wire, and the wire they wrap around the core is completely round if they are round wound strings.

Plus, it wouldn't really be any different than any other nut, it's just the material that changes.
#13
TS.. your idea for a glass nut is possible but not efficient. Glass is at it's peak of strength when it is whole. You need to consider that simply scoring a piece of glass is enough to break it along that score line so having a notch cut into it for your strings and the pressure of the strings pushing down on it will most likely crack the nut. Your best option, if you're really interested in attempting this, is to used tempered or laminated glass. Whatever you do though, DO NOT heat the glass up to work it. Heating up tempered or laminated glass will cause it to loose it's strength. Instead, try using diamond coated files to make the notches for your strings. (This is the part where it gets less efficient... diamond files are $$$$$!!) Hope this points you in the right direction. Good luck with it though, and ifyou do attempt it, let me know how it turns out.
#14
only way to probably do this would be to have a mass production of nuts, made one size fits all in molds and molten glass used? then use flat wounds, and no tremolo. probably on a short scale guitar for less tension. my 22.5 inch scale duo sonic fits the bill :p
#15
I think that if the grooves were 'forged' in while the glass was hot, as opposed to cut and polished, that there would be less chance of breaking. After being formed, the glass would have to be tempered, but once it is tempered, glass can be Very Strong. It seems like a lot more work than making a metal nut.
#17
String vibrations would cause it to chip away eventually if it wasnt made properly since its extremely brittle. Since the nut only needs to be hard enough to not wear away easily under the strings, theres no real point in having something that hard. The only thing one could use that is similar would be diamond or hardend metals like tungsten carbide, both of which are overly expensive for something as simple as a guitar nut.

Geez this has stirred up plenty of interest, i recon someone needs to actually give it a bash. How about it TS?
#20
I don't think it would work well at all. It's going to be a bitch to try and make and then once you do make it, it's probably not going to stand up very well to constant vibration from the strings...

Maybe, it's a lot like flint, and that it chips away in very sharp chunks, don't know if you could ever get a round edge on it, it is very hard, and doesn't chip easy.

You could use basic Mineralogy to figure this out.
Find out the Hardness of glass on Moh's scale.
How many cleavages does it have?
How many fractures does it have?

I believe Glass is around the middle of Moh's scale. Don't quote me on that though, I don't do too well in Earth Science class.

If you could get your hands on some diamond, that'd be amazing. According to Moh it's the hardest material in the world.

I think glass would be a great nut material. I'm going to guess that the reason it's not used is 2 fold.

1 shaping it would be expensive?
2 how to you attach it to the guitar?

I know it would be possible to attach it and to shape it but with the other good materials we have, I think that nobody has bothered with glass. I'd like to see it but I doubt I ever will.

Obsidian is volcanic glass, nothing remotely close to what it is in Minecraft. It only breaks apart into flakes and shards, not good for anything other than jewlery.

Well the Aztecs forged an empire based on an army armed with obsidian. The blades reputedly could decapitate a horse. Or you know cut out the beating heart of your human sacrifice

Lexan would definitely work. Infact I kind've want to make a Lexan nut, now.

When you say everything is in the wrong place, you mean the " and the @ sign lol. Seriously though i didn't see any typos. He was on the "who NOT to listen to" list though so that should tell you all you need to know...

^I don't know how most British keyboards are but this laptop has a lot more than 2 keys moved around. It has a lot more keys in general, the shift and enter buttons are a different shape, but what makes it really tough is that all the keys are smaller and I've been typing on the same keyboard for 8 years so everything is in the wrong place for touch typing.

and not having been here for several months I guess I missed out on the individual I was for some reason compared to so I still don't really get the joke. Oh well...
