** 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.  —­Contributed by Jno.  E.

** 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. margin, pasting down smoothly.  Cut a piece of stiff paper to fit and paste on the back.  Take a piece of cloth as wide as the cover, and long enough to extend over the back and 1-1/2 in.

Beyond each “strip.”  Paste on to hold all together.  Two pieces of paper the exact size of the magazine, pasted on the inside of each cover protects the edges of the cloth, and adds to the appearance.  Let dry slowly.

[Illustration:  Magazine Binder Complete]

With backs and edges of magazines even, place in a vise and set up tight allowing 3/4 in. from back to show above the vise.  Bore three 3/16-in. holes 1/2 in. from the back, one in the middle, the other two 1-1/2 in. from each end.  Make corresponding holes in the strips of the binder and use the shoestring to complete as in Fig. 2.
