    Default Low G Nut Slot File

    I have a couple re-entrant ukes that I'd like to switch to linear, and I have several different low G strings, though I don't know the exact gauge for some.

    I'm not a builder and don't have the tools to do even a simple set up. But since I'm not able to take my ukes to any luthiers, I'm thinking about getting a nut slot file. Since I won't be building ukes or even doing set ups, I wanted to see if I can get away with getting a single file from StewMac.

    My understanding is that most non-wound low G strings are similar in size/gauge, and that the nut slot should be a few thousandths of an inch larger than the string.

    Is it possible to get a single nut slot file to create slots that will accommodate most low G strings? And if so, what size would that be?

    Naw, I wouldn't spend the money for a slot file just to widen one slot on a nut. Use an acetylene torch cleaning file. Slow, but works. Available at most automotive stores. $6 USD.

    Thanks. In trying to research this, Iíve seen this recommendation a few times, sometimes along with a hacksaw. But I guess I was hoping to see if anyone here could recommend a nut slot file size. While multiple files or sets are expensive, a single file is cheap enough that, if having only one is feasible, it seems like it would work better than hacksaws and torch files. Especially if I end up doing more ukuleles in the future.

    I was hoping there was maybe a popular size that people use most often for low G on linear ukes.

    Depending on the instrument setup and string choice, you may not need to do anything. Often they fit fine. Plus, many of the wound low G are smaller in diameter than the C string. At the most, you might need a wee bit wider nut slot. A couple swipes with a SMALL round Swiss file will do ya. You don't need to make it deeper but only slightly wider.

    If you decide on a file from StewMac rather than another approach, the .032 will do just fine.

    Sorry, what's a small round swiss?

    Thanks, my research so far had me looking at the .036 or .042 to make slot widths for most low Gs. But I was second guessing myself.

    I didn't know either. This is what I found.

    Sometimes they're called needle files. They're just small files for precision work on small pieces. Often made in Switzerland, hence Swiss files here in the States. I have a set, Craftsman Needle File Set no. 96757. I also have a set of the StewMac nut files and I like them for cutting new slots, but find them bothersome when I merely need a slight widening of an existing nut slot.

    Snowden, have you tried installing a low G? I have tried several different low G strings on my equipment and haven't had a problem. Be sure you try first before making any alterations.
