    Another tool that can be used that is much handier is a set of
    'feeler gauges'. This is a set of metal strips usually about 3/8"
    (10mm) wide & 2 - 3" (50-75mm) long. The strips are different
    thickness starting about .001" (.000039mm) & going up to about .035"
    (.09mm). Thicknesses not represented by a single feeler can be
    checked by stacking 2 or more gauges together. Feeler gauges are
    usually under $10 depending on the quality & size. 

    They're generally available at stores that sell tools used by
    mechanics & machinists.
