The Union compass plane otherwise known as the Union circular
plane is a 10 inch long metal plane with an adjustable flexible sole.
The plane is used for planing timber which has a curve such as the edge
of a round table.
The flexible sole can be adjusted to form a convex sole or a concave
sole, set to the required curvature.
The flexible sole is anchored with the frame at either end of the sole
with the frame meeting the sole at the center.
The sole is adjusted by turning the knurled sole adjustment wheel nut;
located on the top of the plane towards the front.
The plane has graduated toothed plates on one side of the plane. These
graduations can be used to assist in setting the desired radii.
Once the sole has been adjusted to form the desired curvature, the
adjustment wheel nut is locked by securing the small locking screw just
under the adjustment wheel nut.
Similarly the small locking screw should be loosened before turning
the adjustment wheel nut.
The frame shape and front metal knob provides handy grips to handle and
control the plane with ease.
The plane blade and cap iron are locked in position with the lever cap / screw cap.
This helps to reduce chattering.
