At the age of 77, I have problems with the steel strings, as they go deep into the fingers skin, making hard to play after 5 minutes.
I thought was a problem of action for my 60 years old acoustic guitar, but I measured and found 3 and 4 mm, which matches the average indicated in this post.
I will need to use a file lo lower the action, as at that time there was no bar, and the bridge was fixed. The neck is straight. Not easy.
Any suggestion for hardening the fingers instead? As I am no more playing long enough to allow the build up of callous. Any cream?
Having used both a file and sandpaper on bone nuts and saddle, I will never use a file again. Bone will glide on a file and require a lot of pressure to cut. Sandpaper requires much less effort and give you better control. Get a quality 320 grit paper, lay it on a flat surface or use a small sanding block. 320 is fine enough for the finish on bone while coarse enough for material removal.
You were using a blunt or a cheap file. Files work extremely well on bone. If they can work mild steel they certainly can work bone. They clog when working bone but it's extremely easy and quick to clean them. They give as much control as sandpaper, maybe more. If it's a one off then it's not worth going to the trouble of buying files.
You may be right, the file is not new and not at its sharpest. It's a Johnson, made in USA 1-7/8" wide x 14" long, second cut. Looked up second cut: a file having teeth of a grade next finer than bastard.
What type of file is best for sanding down the bottoms of bone nuts and saddles.
