Today I feel like I have been "doing a Jocko" in that I came home yesterday with a 7 year old's new guitar, which is an Ashton 3/4 size mini guitar, steel-string, dreadnought style, and today I filed down the sharp fret ends (a first for me), put a new nut on, changed the steel strings to nylon strings (because his teacher insists he has a nylon-strung guitar) and put some washers under the strap buttons, sort of home-made straplocks that were free because I had two spare washers.
The challenge for me was that his guitar teacher at school (where, sadly, they only teach classical guitar) said that it would not be possible to put nylon strings on a streel-stringed guitar because the tailpiece is different, while his parents are saddened as their son was given the guitar by a family friend and they don't really want to have to return it and buy a classical guitar, especially as the little lad's aim is to learn chords and songs.
To make classical strings workable on this guitar, I tied a figure of 8 knot in the end of each string and used the little ball-ends from the old strings. The trick works and, as you can see, it looks good. Another satisfied customer, so to speak!
