| A carpenter's
square. It has a long side, about 49cm, and a short side about 24cm, and
looks like an L shaped ruler. Also sashigane wι. It is used to take
measurements, make right angles, and mark with India ink on a marking string,
sumikake n|―. The carpenter's square is made of steel or brass and
originally it was graduated in the shaku Ϊ, sun ‘ and ri
system of measurement. Today the metric system is used. Gradations on
the frontside of old kanejaku were divided into 1.5 shaku
to 1.6 shaku on the long side, and 7.58 sun on the short
side. The gradations made on the back urame Ϊ outer edges are the
square roots of those on the front side. These gradations are called *uragane
ι or urajaku Ϊ. The gradations on the inside back of the arms are
the same as on the front. They are called sashigane, kane
Θ or magarikane Θι. The back gradations were devised to handle the
corners of the roof around the eaves. |
