Part 3 (1/2)

Sea Green 3/8 oz lareen 1 ozcolors are used in sufficiently large quantities to alter the consistency of the paint, add one-half asenamel as a finish for toys, care should be taken that the surface of the toy is in proper condition To obtain good results proceed as follows: Give the wood a coat of shellac Sand lightly and dust The following coat should consist of part of white paint and one part of the enahtly tinted with the finishi+ng color, if the finishi+ng coat is not white Alloenty-four hours for drying thoroly; then sand with No OO sand paper Next apply a coat of enamel of the color desired for the finished work (Enaround in oil)

Should the enaallon of enamel Turpentine may also be used as a thinner for enamel

A better finish of ena the enaer body and of course makes it more durable

Because of its durability and for sanitary reasons enalossy finish is attractive and very appealing to children

30 The Dipping Method--When a considerable quantity of toys is to be finished, the problem to be faced will be the cost of application of the paint rather than the cost of the paint itself The dipping process, (i the material to be covered) is found to be the , where so many small parts are used

Many of the s process at quite a saving of time and labor, with probably better results than where the application of paint or stain is done with a brush

The success of the dipping process depends on the arrange is done and while they are drying Here the exercise of a little ingenuity on the part of the students and teacher, will overco that a number of checkers, or handles, or s 8 could very easily be prepared You will notice the screen tray (which is removable), and the tin sheet which slopes towards the container The small pieces to be stained can be handled in wire baskets with h so that the pieces will not fall thru

The wire basket is then immersed in the container and worked up and down, so that the liquid will penetrate and touch all pieces It is then pulled up and swung over the screen tray, where the contents of the wire basket is dumped Here, the superfluous paint will drip off on the tin sheet, which, because of its slope, will cause the superfluous paint to flow back in to the container Fig 9 shows the dipping frame in use

The screen tray can be re Several trays could then be made and a rack to hold them could very easily be constructed

The paint used for dipping purposes must so be prepared that too much does not run off or too much stay on, for this is surely one way to spoil the work It should be thinned to the right consistency and care should be taken that the thinners used are of the best quality

Where larger pieces of work are to be dipped, wire attach separately over the dipping frame until ready to be placed in a rack If the wire attach up the toy until drained and dried In re the toy from the paint it should be drawn out very slowly so that the surface of the paint may be left as smooth as possible

Where one desires line effects on toys, thesebrush or sign painter's pencil

[Illustration: Fig 8 Dipping fra fra---Excellent results in polishi+ng large quantities of s The material to be polished should be thoroly dry The parts are then placed in a tu 10 Cut up paraffine wax into s about one-fourth pound to each tumbler full of toys Allow these to tumble several hours This will distribute the wax evenly over the parts and produce a polished surface

The tu 10 is turned by hand, altho it could very easily be placed in a lathe, where one is available

32 Care of Brushes--A suitable place should be provided for brushes that are not in use A tin-lined keeper is recommended Brushes should be suspended so that their bristles will not touch the bottom of the keeper, and have the liquid in which they are kept come well up over the bristles, so that none of the paint or varnish may dry in the butt of the brush

33 Paint Application by Means of Coreat advancement has been made in the application of paint byequipment was confined al materials such as japans, enamels, lacquers, varnishes, etc, on manufactured products But in the past few years improvements have been inally experienced and make possible the use of this s, shi+ps, etc; and at present, a large portion of factory maintenance work is done in this manner Excessive fumes have been eli the volatile thinners, solvents, binders, etc, thru air reduction This is brought about thru the use of low pressure and the perfection of ingenious patent nozzles and other i 10 Tu small pieces]

34 Uses of Pneumatic Sprayers--Pneumatic paint sprayers, or air brushes, are extensively used in themachines, telephones, electrical equipment; in fact, very nearly all manufactured products, as well as on shi+ps, structural steel and iron work, bridges and buildings

The speed of the air brush is very great compared with hand-brush work

Usually, an air-brush operator will accomplish as much in one hour as a hand or bristle-brush worker will in one day; and it is possible to obtain an even coating, free fros, runs or brush-marks and better results are obtained than with the hand brush method A film of paint can be applied in one operation equal to two hand-brush coats, as it is not necessary to reduce paints by thinning as reatThe air sprayer can also reach places inaccessible to the hand brush, and a perfect coat can be applied over rough, uneven surfaces, which could not be obtained by hand-brushi+ng

In considering pneu to be kept in mind is the proper application of materials This can be successfully accomplished only thru the use of co only sufficient main-line air to lay the paint, enamel, varnish or whatever finish may be used, on the object Excessive pressure results in fu place By air reduction is meant the removal of the more volatile solvents, thinners, binders, etc, thru evaporation, and the material thus loses its adherent and coherent properties

Both types of air-brush equipment illustrated here require three cubic feet of air per minute to operate and the pressure necessary depends on the density, consistency or viscosity of the material used For example, undercoaters, japans, etc; require from twelve to fifteen pounds of pressure to apply perfectly; while enahteen to twenty-five pounds Water stains require about five pounds of pressure
