Lawrence,
engineers in the old days used to just throw
the prints over the fence (stayed away from the dangerous animals ie the welders
)
help on a real note
the hole is square, so the engineer
is calling it a square weld
but remember the prints they threw over the fence
we burned them for fun
prints????????? we don't need no stinking prints
