I just thought I would use the blog feature to pass on some of what I have learned building cigar box guitars.
If you are still using a ruler to measure where to cut the frets on your fretboard or neck you are working way too hard!
I measured and marked (guesstimated really since my ruler lacked the precision required for the job) the fret lines for cutting on my first cigar box guitar. I found it challenging to say the least and hoped I was accurate enough.
I discovered the WFret program (see link above) for Windows by Jonathan D. Whitney on the web and gave it a try. I will never measure by hand again. I have used it for 24", 24.8", 25", 27", and 30" scale length fretboards. You can pick a popular scale length from a list or be adventurous and enter a custom scale length in inches or millimeters and you can print a template. I tape the template to the fretboard and just cut on the lines; it couldn’t be easier.
