Divide
150mm into 4 Equal Parts - not as difficult as you might think.
Instead of dividing 150 by 4 and marking your timber every
37.5mm (which is a nuisance) angle your ruler or tape measure
along the edge to 200mm (see diagram).
 Now you can easily divide 200 by 4 and mark the timber every
50mm. Do this on both ends of the timber, rule along the marks and
you will have a 150mm piece of timber perfectly divided into
quarters without all the brain strain.
The width of the job can be almost anything, as
long as your rule is long enough to angle to a number that is easy
to divide. Some examples include, 4.5m - angle the rule/tape to 6m
then divide by marking at 1m or 2m intervals or for 250mm - angle
to 300mm and divide by 20mm or 30mm.
What about the kids' assignments when they have to
draw a table to put information in, or cutting out a piece of
timber to slot into another piece, or working out where to put
expansion joints into a new concrete driveway? What about
measuring around the yard planing your garden bed or landscaping?
This is a handy hint to remember. |
