I've got a cheap Chinese fiddle, and its nut action is too high. Can I lower it with just one tool, or do I need a few? Shall I just get a fine general purpose woodwork file, or is there something better? The end result will be given Helicores and be used for country music, so nothing fancy. All it needs to be is robust, probably. Sorry, I flunked woodwork at school (one of the bigger regrets of my life!)
I think I just ended up using an emery board because I could bend it. Then on ebay I found a cheap box of tiny round files for the string cuts. $3. Put masking tape on the fingerboard and everywhere else is needed to keep it from getting scratched. Nuts can be popped off and replaced, but its better and easier if you don't mess up too bad. I did start off with a stiffer file to get it down to approximate size quickly. Have fun.
