Stanley 140 Review By: I.Ball

Manufacturer: Stanley

Plane Type: Block

Model No: 140


The Stanley block plane number 140 is a specially designed skew block plane (with an angled mouth), a wooden front knob (usually rosewood), an adjustable blade, and a removable side wall.

The Stanley 140 is very good at working difficult wood including end grain work to produce a super smooth finish.

The Stanley 140 is able to work difficult wood due to the skewed mouth and a blade set at a low angle, a combination which is well suited to producing the best results on tricky wood.

The number 140 has a blade depth adjuster located at the rear of the plane below the blade.

The depth adjuster is operated by a wheel; turn the wheel for a finer or deeper cut.

The wheel has five small rimmed circular holes pierced through the face, a central raised full circle outlined by a rimmed circle. The edge of the wheel is knurled.

The right hand side of the plane (as looking from the rear) is detachable. The removal of the wall allows the plane to be used as a rebate plane.

The side is held in place by two screws; one located between the front knob and wall, and the other located towards the rear between the depth wheel adjuster and the wall.

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 through the face and has knurled edges. The lever cap has a plated finish.

The lever cap has a curvacious head, an angled bottom edge and an extra raised wall protruding from the right hand side (as looking from the rear).

A modern day version of this plane has been produced in the form of the Lie Nielsen 140 block plane.
