Apologies for the pun! As you can see, both of Adrian’s
instruments now have their necks and fretboards fitted and both have been
fretted. The tenor’s neck has been roughly carved and will get its final
shaping next week, whilst the octave’s is still square.
Whilst fretting, I’ve been using a fret rocker to test
whether or not each fret is level with the previous one. I don’t know who
invented the “fret rocker” but I bought mine from a chap in Portugal, who sells
them on eBay.
The differing lengths of the edges allows you to compare only three frets
at a time (if the middle one is high then the fret rocker rocks) as you progress up
the fretboard and the frets get closer and the straight edges need to be
shorter. Checking each fret individually ensures that they are all seated properly.
Apart from checking
whether or not frets are level, it makes a great mini straight edge for all
manner of checking.
