Marples M-77 Review By: I.Ball

Manufacturer: William Marples

Plane Type: Bullnose

Model No: M77


The Marples bullnose plane M-77 was made by William Marples who produced a whole series of metal planes which emulated the Record planes of the time.

The M-77 was based upon the Record 077 bullnose plane with the two planes being almost identical with the exception of the planes colour and markings.

The Marples M-77 was finished with a black lever cap, polished sides and sole and a red finish on all other parts of the plane body. These colours were the typical colour scheme used on the William Marples iron planes.

The Marples M-77 bull-nose plane is a 4" (10.2cm) adjustable, fixed nose bull-nose rebate plane constructed from cast iron.

The body cast is one solid piece with a fixed nose. There are similar versions of this plane made with a removable front nose such as the Record 077A bull-nose plane.

The plane can be used left or right handed and can be laid perfectly flat and used on either of its sides to trim rebates, shoulder lines and tenons.

The plane has curved areas on top of the plane offering added comfort and control.

The Marples M-77 bull-nose plane is equipped with a blade adjusting mechanism. The blade adjuster control is located at the rear of the plane in the form of a knurled nut. The adjuster is used to control the depth at which the blade will cut.

The plane is fitted with a shouldered steel plane blade. The cutting edge is 1 1/8" (2.9cm) wide with a bevel edge. The top of the blade has a slot to allow the blade adjuster to locate with the blade. The blade sits in the plane with the bevel edge side facing upwards.

The blade is held firmly in place with the use of the securing cap / lever cap. The cap locks the blade in place by locating the securing cap into the two notches in the plane body and then turning until tight the knurled securing wheel located on the underside of the securing cap.

This model of plane has more recently been revived in the form of the Clifton 770 bullnose plane. Like the Marples M-77, the Clifton 770 is also a fixed nose bullnose plane.
