BILL FILE

This is a useful article for filing notes or memoranda of things that

need immediate attention. There is very little variety in design. The

base can be made square, circular, six-sided, etc., and decorated in

many ways. It looks well either in copper or brass. Only heavy copper

should be used, in order to give weight to the base.

[Illustration]

_Material:_ A 3-1/2-in. square of No. 10 copper. Rod of sharpened steel.

_Directions:_ Take a piece of iron 1/2 × 2-1/2 × 2-1/2 ins. Go to any

scrap heap for this. Place the copper sheet over this block of iron,

letting the surplus metal extend evenly all around. Put it into the

vise with the corner vertical. Tighten it up and drive the metal over

the corner till it touches the sides of the iron. Do this on all the

corners. Make the outside of the metal fit tightly over this iron,

acting as a shape or form. If the metal should feel springy before

driving it up close, anneal it. Notice that in driving these corners

down they are longer than the four sides, and they suggest feet. If

filed flat and smoothed up you have a square box with a foot on each

corner. Take it off the iron form and make the top rounding by driving

it over the hollow block. Now drill a 1/8-in. hole through the middle.

Place the copper rod in the hole and solder with hard solder.
