S&S Upr.Bridge Cap Question

[Jon Page]

I have a plexiglass blocks with six bridge pins drilled in.  There are several
executions for length and width.  Once the center line is established and string
length, the center two pins are lined up and the block struck. All pins are
mapped
perpendicular to the string.
