problem with graphite nut


Recommended Posts

on my last (or rather, 1st) project guitar, turned a strat into an unconventional installed OFR, by installing OFR but having a graphite nut and lokicng tuners.

now, in two months the string has eaten through the high E groove........ it was fine when i had it cut, buzzed a little a month later, i made action a bit higher, it was fine, but now the buzz has caught up with me - evidence its being eaten through continuously.

now, the tuning stability is amazing, and i can easily retune with this setup, so the graphite has performed very well........ but since it is buzzing really badly when the high E is picked with strong fforce (esp uding strumming), coz the groove is too lw, i will need a new nut fitted shortly.

this has only happened on the E string - why? i abuse the OFR a lot, but moslty on G open harmonics and just very wide vibrato, so i am confused to why its done it, esp as every other groove is fine.

graphite appears to be a rather soft material then - then why is it used as guitar nuts? i use 10's in concert pitch, so i dont understand.....

but more importantly, now that i'll get a nut replacement, a new graphite nut, with hope it wwont be eaten through nce again? or a bone nut - from a singnificantly stronger material, but will it be as stable and in tune after minutes of trem abuse??

this replacement will cost me $30/£20 because since i do not have jewellers files, (which are ridiculously expensive), i have to get it slotted by techs, whicm means i cant just get away with bying a blank and thats it, and whats annoying they'll charge the same to cut and fit it as they would to just slot it....

so 3 questions,

1)why has this happened?

2) should i get graphite or bone nut replacement?

3)would bone hold out as nicely after trem abuse (i do have schaller locking tuners and a perfectly serviced OFR)......

:D

thanks,

i wanted to use a locking nut, but the neck was not intended to have a locking nut, and drilling holes for one would substancially weaken it..... but there's not enough space.

so a bone/graphite nut is a no-no? but surely bone is much stronger?

the other option would be to add wood to the headstock, so a locking nut could be fitted..... next problem is that the nut is only 40mm wide, and just about every FR/Kahler nut is around 43mm

i know thats a major problem....... but it feels really nice, its my fav neck out of all guitars that i've played........ but it means hardware is a pain.

isnt there this lubricant stuff also?

i do think its the only option sadly enough

also means i wont be copying the profile of this neck on any future projects, because as much as i like it, the hardware is far too big a problem........ and i could live with the extra 2/16" i suppose :D

you can buy graphite lubricant which comes in small pots with a thin dripper top i think. if you got a new nut such as brass then you could just use that. its basically just thin instrument oil with finelly powdered graphite in it so it shouldnt cause problems with finish etc

ok thanks, will install the brass nut shortly.

i didnt want to start a new thread, so i'll just post in here...

i've got to do some tidying up after the project as i just rushed it just to get it playing..... ok

1) is a clear coat a must? i've stripped mine down to sealer, and i love how it looks, and i dunno, is it necessary to finish it with laquer? i dont mind dents and what not on this guitar - it has that rough/beat up look on purpose.....

2) the electronics hum/buzz if i'm not touching either the strings/bridge or knobs (i have metal knobs)....... grounding problem....... but i know for a fact all grounding is done correctly, and there is a solid connection from volume pot to bridge........ is this because knobs are metal and are in direct contact with pots? so could i sort this out by just stiking masking tape (for example) around pots, so its no longer metal to metal? or why is this?

3) do i have to finish the neck with oil / laquer? it feels really really nice as bare wood, and i hate sticky laquer finishes but i dunno

4) my floyd does not pull up as easily as it should..... fulcrum posts are installed correctl,y but i think its because of the springs not being stretched out in a level form, they are sort of curved, so to pull up fully, you have to push them in, until they pish the spring claw down...... can i solve this by placing the spring claw lower down so springs are no longer bent?

That's why I've only ever used it once, and hated it. I prefer good 'ol bone.

yeah, i learnt it the hard way........ but its really cool to work with though, can polish it up to mirror like reflection and its a joy to file and sand........ clearly the string had a field day eating through it too.

but could you guys please answer my questions......... sorry but its kinda urgent and i'm relying on your expertise

In that photo, are the strings tuned up to normal tension? If they are, the springs should not be fully contracted as they are, and the trem block should be perpendicular to the body.

no, its with 2 strings broken (well i do like to abuse my good ol' OFR)......

but my point is, it will not go very far at all even from there, so from when the FR is setup correctly, its not doing the scoop of +2/3 steps a FR should be able to do, you know?

Your sustain block is too long. that's why the springs are curved
