LARGE ELLIPSE SERIES
Size 10" X 16" each template
MAJOR AXES 2-3/4 THRU 4
T-93-A Set 5 templates (10 projections) - 15°, 20°, 25°, 30°, 35° - 16', 40°, 45°, 50°, 55°, 60°
T-93-B Set of 2 templates (4 projections) - 15°, 30°, 45°, 60°
T-93-5 single template 5°
T-93-10 single template 10°
Each template is 10 X 16 inches and has two different projections, with six full ellipses for each projection. Exact pin-point centering is provided for both axes. One side of the 4 inch ellipse for each projection (sets only) is surrounded by pinholes spaced at 15°, thus providing a protractor for that particular projection. The user can thereby divide the ellipse into various equal parts without the customary projection steps. A radial line through the pin-point will provide the correct division for any ellipse of the same projection. |
