The original cost is more,but the facility for doing work is greatly increased;there is then no variation in current, and a dynamorequires practically no attention. A dynamo depends for its current upon the fact that acopper wire, passed between the poles of a magnet, willgenerate a current of electricity in the wire; this cur-rent bears a definite relation to the strength of the magnetand the number of times the wire is passed between thepoles. From this it will be seen that the size of wire,the strength of the magnet and the speed of revolution 3Q MODERN ELECTRO PLATING. all have a bearing on the current produced and that byaltering the various factors given above we can obtainthe quantity and strength desired. Before dynamobuilding had attained its present state of advancement,great difficulty was experienced in producing currents oflow voltage by this means, and the older dynamos were. •i Modern Dynamo. very apt to burn the work; hence the notion, still heldby many old platers, that the dynamo is unsuited to doreally hard and durable plating. This is completelyovercome in the modern dynamo and the much lowerspeed of the modern dynamo makes them at the sametime less expensive to run and more durable and longerlived. Therefore the plater who is tempted to buy asecond-hand machine, on account of its low price, may MODERN ELECTRO PLATING. 31 find it the most expensive machine he could use, and befinally obliged lo throw it away and get something up todate in order to get the cost of producing work down toa figure that will leave him any margin at all. Whenbuying a dynamo, see that it is a modern machine. See that it will do your work. See that it does
