and 4. Hold the brass strips apart by means of the hard rubber
strip and screws. Do not let the screws come all the way through
the rubber strip or you are liable to get a shock in case you
should touch both screws simultaneously. Screw a rubber handle
onto the rubber strip to move the lever back and forth with. Fig.

detail. Fig. 3 is an end view of the same.

** Cleaning Bronze Bearings [405]

Bronze bearings may be cleaned with a solution of washing powder
and water run through the oil cups while the machine is running
without any load. The solution, cutting out the dirt and grime,
will come from the bearing very black. About 1 pt. of this mixture
should be run through each bearing, then clean thoroughly with
clear water.

** A Water Candlestick [406]

A glass of water makes a fine emergency candlestick. Weight one
end of the candle with a nail just large enough to hold the candle
in the water so that the water comes near its top edge, but does
not touch the wick, and then light the candle.

It will burn until the last vestige of wick is gone and the flame
will not flicker. The melted tallow that runs down but serves to
hold the candle more stationary.

** How to File Soft Metals [406]

When filing soft metals, such as solder or babbitt metal, the
file, after a few strokes, will become filled with metal, causing
scratches on the surface being filed. The surface may be filed
smooth, provided the file has been well oiled. The oil prevents
the cutters from clogging and also allows the metal to yield
easily. Oil the file every few minutes and use a card frequently
in cleaning and the work will be smooth.

** To Make a Magazine Binder [406]

Get 1/2 yd. of cloth, one shoestring, a pasteboard box for covers,
and some heavy paper. Cut the pasteboard into two covers, 1/4 in.
larger all around than the magazine, except at the back with which
they should be even. Next cut a strip 1 in. wide off the back of
each cover. Place the covers on the cloth, Fig. 1, with the back
edges 1/4 in. farther apart than the thickness of the volume to be
bound. Cut the cloth around the covers, leaving 1-1/2 in. margin.
Paste the cloth on the covers as they lay, and turn over the 1-1/2
in. margi
