           Selection and determination of slip gauges for

           different sizes

           Objectives : At the end of this exercise you shall be able to
           •   determine slip gauges for different sizes.


           For determining a particular size, in most cases a

           number of slip gauges are to be selected and stacked one over the other by wringing the slip gauges.
           While selecting slip gauges for a particular size using the available set of slip gauges, first consider the last digit of
           the size to be built up. Then consider the last or the last two digits of the subsequent value and continue to select
           the pieces until the required size is available.
           Example (Without using protector slips)
           Building up a size of 44.8725mm with the help of 112 piece set. (Table 1)
