How to Make a Mitre Box
Although the construction of this labor- and time-saving device
seems at a glance to be very simple, a great deal of care must
be exercised in the making of a mitre box.
But very few tools are required in making a mitre box, and even
the handyman about the house generally has the requisites.
Below are given two methods of making a mitre box. The object
of this is to show that a box can be made with different tools.
Fig. 7 shows a full working drawing of a mitre box. The simplest
way of making a mitre box is with the use of a mitre try-square
(Fig. 8). This tool has been on the market for a number of years;
room should be made for it in every carpenter's tool chest.
With the use of this tool, a saw, and a hammer and nails, any
handy person can make a picture frame.
For the ordinary mitre box, take three boards, the two for the
sides being 1/2"x15"x5"; the bottom piece should
be 1"x15"x4". The box when put together will
be 5 inches wide from side to side. Now mark off 5 inches, AB,
on any part of one of the sides (Fig. 7). Then place the mitred
try-square at A and mark from A to C, E to G. Also from B to
H, F to J. Now place the square on A and mark side to K; also
from B to L. The same operation is employed on the other side
from the points G and J.
The box is now ready for the sawing of the mitre cuts, with which
much care must be taken.
