02 Which type of dado blade should I buy, the dial (wobble type) orthe stacking (chipper type)?
The wobble type is very simple to use with infinite settings
between approximately 1/4 inch and 13/16 inch. It does not produce
true right angle cuts because of the design.
The chipper type doesn't have the same infinite setting for width.
You can achieve nearly infinite settings by adding shims with
thicknesses of 1/32, 1/64, 1/128, etc. It will cut a square bottom
on the dado, but it will also leave 2 grooves on the edges of the
dado. The reason for this is that the blades are slightly larger
than the chippers. The larger blades are to reduce the splintering.
The blades can be reground to be equal to the size of the chippers
at the possible cost of increased splintering. Some say the grooves
are a benefit because they provide relief for gluing joints.
Many people claim that the wobble type is easier to set up.
The August 1991 Fine Woodworking further studies the features of
the various types of dado blades.
