The Verdict

Review By: I.Ball


Manufacturer: Stanley

Plane Type: Compass

Model No: 20

The Stanley 20 compass plane otherwise known as the Stanley 20 circular plane is a 10 inch long metal plane with an adjustable flexible sole.

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 a screw adjustment in the center.

The sole is adjusted by turning the knurled sole adjustment wheel nut; located on the top of the plane in the center. The screw either pushes the center of the sole down or pulls the sole up to create a curved sole.

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 provides handy grips to handle and control the plane with ease.

The Stanley 20 is fitted with the same plane blade, cap iron and lever cap as the number 3 bench planes. This makes finding a replacement piece a lot easier to find.

The plane blade and cap iron are locked in position with the lever cap. This helps to reduce chattering. The lever cap has a plated finish which is usually a nickel plating. The lever cap has a pear shaped hole in the middle in which a screw runs through, the shape helps prevent the cap loosening.

Also, as with the standard bench planes such as the 3, the 20 compass plane has a lateral blade adjusting lever located just behind the blade. This lever pivots side-to-side which in turn adjusts the cutter side-ways (note: the lever cap must be released when making these alterations).

When looking at compass planes, you may come across a very similar plane which is the Record 020 compass plane. Other than the colour and the plane markings, the Record 020 is almost identical in design.

Tradionally compass planes were made from wood with a fixed sole, mostly with no form of adjustment.
