What do you use as a nut files for 10 & 13 guage (.25mm & .33mm) strings?

    I got a set of welding tip cleaners for filing nut slots to lower the action at the nut but the smallest file is to big for the smallest two strings. Is there a good source of those for the 1st and 2nd strings, 10 & 13 guage (.25mm and .33mm) or is there a Macgyver solution to the problem?

    Try using .010" and .013" nut files...

    Hosco makes 'em, as well as StewMac.

    I bought the stew Mac ones for the first 3 strings, they last years if you look after them, worth the price in the long run. I’ve used those 3 files for like 12 years and they are still like new.
    For the larger gauges I use needle files. Because I can make those work without problem.
    I use Welding torch tip cleaners for fine tuneing or smoothing nut slots, not very efficient at cutting slots.

    Nut work is tedious for me, those stew Mac files were a necessary investment as far as I’m concerned.

    A MacGyver solution is an xacto or similar craft saw set which starts at 0.010". Folded fine sandpaper for smoothing.

    Thanks for the replies. I should have mentioned that I just need the files for fine tuning the slots in Tusq nuts. (I never use Tusq ovaries.)

    Another vote for proper nut files. A trivial investment for a tool that does exactly what it's designed to do.

    Welding tip cleaners are fantastic also...for cleaning welding tips.

    Horses for courses.

    I use StewMac 0010 & 0016 nut files and wrap 1000 grit sand paper around them to get the slot smooth, slightly wider than the string and square shaped at the bottom. I need to wear a headband magnifier when doing this cause it’s a delicate process

    My hands shake enough these days that I can use files several thousandths undersized and still be ok :eek:

    I agree that some kind of magnification is very helpful for this. a headband magnifier sounds ideal. I have been using a loupe. In the past I have considered getting a heaset magnifier and I think I will consider it again.

    Would it be a good idea to get undersized nut files to compensate for hand wobble and to allow for the thickness of sandpaper?

    Be very careful with sand paper! The wet/dry I have is 0.007" so doubled over is 0.014" and my regular dry only paper is 0.011". Doubled over a file, the slots could be like the Grand Canyon!

    I'm going to use a single sided razor blade. Mine are .010" thick which is as thin as any of Stew Mac's nut files. I will file off the edge of the blade. Then I will use a file to round the edge of the blade. Then, using a dremel tool with grinding disc, I will cut sections of the new edge and then file off the burs. That should work to saw the slot deeper for the skinny E string. To polish it without making the slot too wide, I will wrap fine sand paper over a fresh sharp razor blade. For the B string I will use a similar process.

    I would buy Stew Mac nut files if I was working with blank nuts or if I was working with Tusq nuts more than once every year or two. Also, I would be more likely to buy a Stew Mac nut file if they made a thinner file or if I wasn't so cheap or if I didn't enjoy Macgyver solutions.

    I've used a .017" fret saw for both. I'm not sure making the slot the same width as the string is even something you'd want to do? Sounds like a recipe for binding and tuning issues, plus you can't change gauges down the road. I can't see or feel any movement of a .010 string in the the .017 slot at all, but YMMV.

    Bingo.

    A properly constructed slot has several other attributes, all more critical than width, IMO. I readily go .004-006 over the string thickness, without a second thought.

    I was wondering if a wider slot would make much difference and why, unless the string wouldn't return to the same spot during tuning and bends. As long as the slot width is a little wider than a string, the string shouldn't bind in a Tusq nut. Another thing to consider is it is much easier to make a narrow slot wider than to make a wide slot narrower.

    Someone mentioned that a square slot works fine. One possible advantage of a square slot is lubricant could stick in the corners and seep onto the strings to keep them lubed. That is a wild guess and could be wishful thinking.

    I think I will try my razor blade method and use sandpaper over the blade to widen if necessary. I'm retired and have all the time in the world to get the job done right. I wouldn't be surprised if I end up buying nut files eventually but in the mean time I think my MacGyver blade is worth a try.

    2-sided nut files are a good way to go and not overly expensive. I have a Hosco 10/26 that covers the 10, and a 12/10 I can use for the 13 - you can tweak a thousandth up with a smaller file - just not the other way.

    You'd be surprised not just by the time savings but the precision in your setups. If you do setups on anybody else's guitars it's worth it - and for experienced players that are also knowledgable techs there's just no substitute for the right tools.

    A slightly wider slot, rounded bottom. The string will remain at the bottom. It's under tension, remember.

    A flat bottom will allow the string to wear multiple grooves, and that will definitely cause pinching issues.
