Stanley 120 Plane Review By: I.Ball

Manufacturer: Stanley

Plane Type: Block

Model No: 120


A review of the old Stanley 120 block plane.

The Stanley 120 block plane is a 190mm (7 1/2 inch) long plane from the Stanley block plane range.

The Stanley 120 plane body is made from cast iron which was originally machined and ground to offer flat sides and sole straight from the box.

The Stanley block plane number 120 has a wooden front knob, a pierced curvacious lever cap, a paddle depth adjuster and a 41mm (1 5/8 inch) wide plane cutter.

The blade depth adjuster is operated by a lever paddle; lift the paddle up for a finer cut, push the paddle down for a deeper cut.

The lever cap secures the blade by turning the adjuster wheel underneath the lever cap. The lever cap wheel has four evenly spread circular holes pierced through the face and has knurled edges.
