The Verdict

Review By: I.Ball

Manufacturer: Union

Plane Type: Compass

Model No:

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.
