|Measuring Diagonals Easily
The last step to assembling a
case is to make sure it's square. And the quickest way to do this is to measure
diagonally from corner to corner. (If it's square these measurements will be the
same. If not, you'll need to make some adjustments.) Using a tape measure is an
easy way to check for square. The problem is that keeping the end of the tape
on the corners can be difficult. But with a quick modification to the hook of
the tape you can solve this problem.
To do this, simply cut a small
slot on the hook with a rotary tool (or hack saw), see the drawing above right.
The slot slips over the
point of the corner of the project, see the drawing and detail at left. The slot
holds the tape in place for those large projects where an extra set of hands would
be a big help. And it doesn't effect the tape measure's accuracy when I use it
for other projects.
