PROCEDURE ON CUTTING ELLIPSES
Ellipse size determination
Delineate on the work piece axis of the required ellipse
at the angle of 90° and mark the length and the width
of the ellipse (fig. 1). Affix the cross frame (1) to the
work or help piece
(fig. 3) with the help of wood screws (13) or with
bonding tape so that the delineated axis intersect the
centre of the borings at the end of the cross frame
grooves (fig. 2). The cross frame is now centered on the
ellipse axis.
Major semi-axis setting
(fig .5) Insert the slider A into the centre of the cross
frame and the slider B in the direction of the major
(long) semi-axis. Loosen the control screw of the
slider A, set the required semi-axis length by shifting
the distance rod in the centre of the slider A pin and
tighten with the control screw (the screw of the slider B
is still loose and the rod passes free through the pin).
