Ever since I watched the video "Mastering Woodworking Machines" by Mark Duginske, I have been keeping sticky-notes pads in the shop for use as shims in making fine adjustments.
Today I needed to run some dados to house cabinet backs and drawer bottoms of 1/2" prefinished birch plywood. I set my dado blade (Forrest) for 1/2" which produced a dado that was a bit too narrow for a reliable fit. I didn't realize that my dado shims were 5/8" bore (my saw has a 1" arbor) so I had to devise another way. Since I needed to add about 0.020" to the dado width, I used stacks of five sticky-notes on the inside face of the outside blade as shown in the picture. The fit on the resulting dado was too loose - I could easily slide two sticky-notes in the void so I removed two sticky-notes from each stack. The resulting dado had the tight but not too tight fit I was looking for.
