Like I said earlier the dimensions on this table design are going to be
completely dependent on the cooking sheet which you use as your top.
While you can get thick industrial cooking sheets I chose to use one of
thinner home use models.
Drilling the Vacuum Table Top
In order to mark off the grid of holes onto the sheet of metal I taped down
graph paper onto the cooking sheet.
In order to mark the cooking sheet at all of the points that were to be drilled
out I used a hole punch and dented the board at each of the points to be drilled.
The left most picture shows drilling pattern that I tessellated across the sheet.
The right picture shows the pattern set against a one-inch square hole pattern.
