making a cigar box guitar part 2 - the neck
This a brief description of how I make the necks. I use hardwood like oak or mahogany usually recovered from old furniture and ripped down to approx 20 x 30 mm section and about a metre long. I round off the corners slightly with a plane and rasp then sand down smooth.
I use another guitar neck to find the positions for nut, bridge and frets. I have made a template on thin MDF and use this to mark the positions in pencil allowing sufficient length for the headstock and for the neck to pass through the length of the cigar box and protrude about 50mm for attaching the ball end of the strings.
I mostly use 3 in a line tuners which means you need to remove some material from the front of the headstock to create an angle for the strings to drop down to over the nut (look at a Fender for the principle). I mark the positions of each tuner post and drill three holes for them to pass through.
I place the neck over the box so that the bridge will be about 1/3 up the length of the box and mark the neck about 10 mm inside where the box ends will be. This section which will be hidden in the box needs about 3mm removing - this is to stop the neck resting on the inside of the lid and dulling the sound.
I cut a small groove across the neck where the nut is to go and glue in a large threaded bolt for the actual nut.
I drill three small holes near the bottom end of the neck abou 10 mm apart for strings to pass through. The fret positions and dot markers are now burnt on using a woodburning tool (or old soldering iron). Also my signature "smojo" on the headstock. I "treat" the neck with a couple of thin coats of tung oil then rub smooth when dry with a cotton rag. Finally I attach the tuners.
This is just a rough guide, if you want any tips feel free to leave a comment or e-mail me.
