No Measure Tape Method:
Blue Painter’s tape is .005” thick, office scotch tape is .0015” thick.

6th string @ 12th fret: .09” TARGET action:
Example, if it measures .1”then (.1” - .09” = .01” too high...
Multiply .01” by 2.2 = .022” thatneeds to be sanded off the saddle at the Bass E. -- In Tape this is 022” = 4 layers blue + 1 layer scotch = .0215” (.0005” tolerance)

1st string @ 12th fret: .075” TARGET action.
Example, if it measures .08”then (.080” - .075” = .005” too high...
Multiply .005” by 2.2 = .011” thatneeds to be sanded off the saddle at the Treble E -- In tape this is .011” = 2 layers blue = .01” + 1 layer scotch = .0115” (.0005“ tolerance)

The tape method lands within a .0005” tolerance.

Place the 6th string tape layers under the wheels one end, the 1st stringtape under the wheels the opposite end, be sure the saddle is orientedcorrectly.

Extra precision: How many frets? Example, for 22 frets we multiply by 2.2,for 21 multiply by 2.1, for 20 multiply by 2, for 18 multiply by 1.8 This may result in the saddle being a tiny bit higher, but it is safe.
