    Can someone tell me if there is somewhere on the web or a book I can buy where I can get fret placement dimensions for a 35" scale bass?

    Any info would be greatly appreciated.

    it generates a PDF that you can print and use it to graphically slot your boards. I used that for a couple of years before I went powerslotting on the tablesaw + jigs.

    Gotta be careful though if you're printing templates. not all printers are perfectly 1:1 scale. I ran into this problem printing PCB masks on my old printer.

    Just measure when you're done and make sure the real thing matches the numbers. ;)

    You can find formulas for it on the internet as well. Just don't use an iterative formula. every fret should be calculated from the nut, not the previous fret. I wrote a very short perl script to calculate it.

    for ($i=1;$i<25;$i++){
    $position=($ARGV[0]-($ARGV[0]/(2**($i/12)))+$ARGV[1]);
    print "Fret#$i: $position\n";
    }%
