- Building a Vane Gear. By C. A. Heisterkamp.
- A newly designed vane gear for 50-800 class model yachts uses duralumin for the vane support arm instead of traditional stainless steel wire to improve performance and durability. The design features adjustable components and allows the vane position to be changed for different points of sail, reducing broaching in heavy winds and preventing the gear from dragging when the yacht is heeled.

D SHOP Railroadvers Since RELIEF model of the city of San Francisco, done ona scale of 1’ to 100’ was recently completed by WPA workers and is now being exhibited to audiences coming from all over the nation to the Golden Gate Exposition. The map, done in remarkable detail, is 41’ by 37’, and is so constructed that it is possible to re- move whole city blocks or whole sections to make any future changes or additions, thus making it easy to keep it up-to-date. The construction of a scale model of San Francisco was first contemplated by the City Planning Commission in 1937. A proposal for the project was submitted, approved by the WPA, and work started early in 1938. The City Planning Commission requested the model to be con: structed primarily for use in city planning studies, dealing with re-zoning, rebuilding, new highway development, etc. It is necessary to use a relief map, or model, in order to show visually and topography, natural the realistically, street grades, the general proportions and sizes of building and lots, and the phy: sical relationship of the various parts of the city to each other and to surrounding areas. The growth of San Francisco was westward from the docking and anchorage facilities of the harbor, and the business and heavy industry reaching out along the lowlands and valleys, the residential construction taking place largely on the adjacent hillsides. In predicting the trend of future devel: opment in by business, two 1/16″ rivets.
