    Question Aluminium extrusions plates tolerance stack up

    Hi all,

    my plan is to build and CNC machine from 8020 aluminium extrusions and aluminium plates.

    I have a quick question about the aluminium plate tolerances. The extruded aluminium has tolerance of 0.008"(Thickness) is that to much for the following build or do I have a tolerance stack up problem? See picture 1
