Need to raise a nut slot. Question about the file.

[dave_bass5]

My E is a bit low and ive decided for the first time that im going to have a go at fixing it. 

I’ve seen how to do it using Baking Soda, and im confident in doing it, but have a question about the file i need to use. Ive seen recommendations for Welders rods, and have looked these up on Amazon.

The question is, do i need to get something that is the same, or almost as wide as the slot itself? All the Welder’s rod sets seem to be very narrow. Is it a case of just using a narrow one and working my way around the slot with it?

 

Thanks for any advice.

Baking Soda? Are you sure?

 

Simply use a drop of Super Glue, let it dry, or better use an accelerator and slightly file.

To file without the right tool (a real nut file), use an A string (in your case) with some sanding paper (800 grit or more) wrapped around it.

Yeah, i thought this was quite a common practice. Obviously with superglue and not just left loose 😀

Yes, this does seem to be the go to method, perhaps it is harder than just superglue alone, it will certainly be easier to see.

I’ve used this method, a short, chopped off length will make it easier to handle, with less chance of a convex finish.

Table salt is a good substitute for baking soda for this application.

Thanks for the replies. The plan is not to fill the whole slot, just pack it out at the bottom by a mm or two, although im sure to get to that I will need to file it. 

I have the wife's baking soda and the glue, I'll get some sandpaper and should be good to go. It's only a plastic nut and if I bodge it up too much I'll get a new one fitted. Should really do that anyway but I need the bass at home for the next few weeks while im learning some songs for a couple of gigs in July.

I had to build up the nut on a ebay neck.

Tape up the headstock from sharp pointy things... think i used a round needle file, twisting rather than back and forth.

Thanks. interesting thread. Hoping to get this done at the weekend. I'll report back if and when I do.

I found when I needed to raise the nut a little a slip of paper did the job enough - might be worth a go before you start hitting it with the glue?

Cheers. There is already a piece of paper in the slot. I was getting buzz from behind the nut a while ago and that cured it, but now i get a bit of buzz on the open E string and can see the string is sitting really low. Fretting at the 3rd fret pushes the string on to the 1st fret.

Cunning Tip.

 

Use paper to get the ideal slot height. Carefully remove string and ensure paper is well bedded down.

 

Use a cocktail stick to apply superglue and make the paper permanent. Cellulose fibres are ideal reinforcement. 

 

Trim ends as needed with a sharp blade.

With all of these fixes, do make sure you use tone: superglue; baking powder; salt; paper.

What type of baking soda is good for metal? 😂

Good idea, cheers.

Ok, i think ive got it all sorted. Got home from work and put a few drops of superglue in the slot while the kettle was boiling. Left it for an hour and re strung. Perfect!!!. 

I didnt bother filing anything, it just seemed to work fine without that, and i took the paper out as well. Im going to put some new stings on over the weekend so will have a closer look to see if it does need anymore attention.

This will be fine until i can get the nut replaced. Not sure how long the glue will last, but as i dont change strings much im sure it’s not going to wear out anytime soon. 

 

Thanks again for all the tips.
