a gate direction to the Beduzierxt tob dimensions for mode llanf ar ti gang-.

When making models on a reduced scale, it is necessary to convert the dimensions of the drawings to the true sizes in millimeters of the desired, reduced scale. There are besides ien Beduziermaästähen not directly usable instruments "to the direct process a model on a reduced scale manufacture · S3 thus remains only one previous conversion to the now determine to be manufactured millimeter" may convert only on the time-consuming exact routes or at the expense of Accuracy with the cup pusher, whereby possible errors cannot be excluded.

Ea is suggested, the gate direction developed and tested by me to use.

This gate direction brings the following compared to the previous methods Gate parts.

The most important part of the door is a considerable time saver for the Conversion * No cup errors can occur either, as only one simply reading the values has to be done. Bas registered in the drawing The dimension is set with the required scale of the tongue on the envelope of the lower part. At the gauze mark dsr tongue the actual millimeter value is then read off. For both large and small values, you can adjust the individual

And by simply adding up to tenths of a millimeter the degree to be determined.

Scalons can be arranged for any desired scale, which is required for the respective production size.

It is important to consider which type of tongue appears to be the most suitable. She with slide rules Bit 4 different scales for conversions is operating or bit 6 Terschiedenen scale for working in the office, designed as a triangular prism tu, where appropriate, in order to be able to draw flat tongues. When choosing the scales, the operating requirements must be borne in mind
