The Verdict

Norris 51-M Review By: I.Ball

Manufacturer: Norris

Plane Type: Infill

Model No: 51

The Norris 51 M plane is a 7 1/2 inch long dovetailed infill smoothing plane made from malleable iron. This plane is also referred to as the 'Norris 51 Annealed Iron Plane' or 'Norris 51 Malleable Iron Plane'.

The Norris 51 M is fitted with a Norris of London parallel iron plane blade, cap iron, gunmetal screw cap and a blade adjuster

The plane body on the 51 M is referred to as a parallel side body. The plane body is also referred to as dovetailed; the name given to a body where the sole has been joined to the sides with the use of dovetail joints. The dovetails can usually faintly be seen at the base of the plane sides.

The plane is stuffed with wooden infills which consist of a front bun and a closed rear handle.

The rear handle has the blade adjuster neatly built into a suitably sized recess allowing the handle to remain as a closed handle.

The blade adjuster allows the blade to be accurately adjusted laterally and moved upwards and downwards to set the depth of cut.

This plane usually has quite a deep mouth to cater for the thick Norris cutter.

The Norris planes were the ‘Rolls Royce’ of their day and are still considered in high esteem today.

Norris A51 or Norris 51?

As I understand it, there is a Norris 51 plane and a Norris 51M but not a Norris A51 as such, or should I say not a plane advertised as a Norris A51.

The 51 and 51M planes are often classed as a Norris A51 due to both the 51 and 51M plane having a blade adjuster like the blade adjuster on the Norris A5's and Norris A6's.

The Norris planes with 'A' in the model number = 'adjustable' so in theory it would follow that the 51 and 51M are A51 and A51M planes.

Please somebody correct me if this is wrong.
