Category: Old Smoothing Planes
Plane Type: Smoothing
Model No: M4
The Marples smoothing plane number M4 is fitted with a Beech rear handle,
a Beech front knob, a 'Marples' lever cap, a cap iron and a Marples
blade. The blade rests on a flat faced frog.
The cap iron for these Marples bench planes have a piece at the top set at an angle with the wording on the cap iron saying 'Correct Angle For Grinding', as you may have guessed the angle at which the top of the cap iron is set is intended as a guide for when sharpening the blade. The design of these cap irons I believe is unique (there are similar).
The blade can be easily adjusted laterally using the lateral adjuster found behind the blade.
The plane is finished with a red japanning.
The Bodies, Frogs and Lever Caps are made of high grade Cast Iron and the Lever
Caps are Plated.
The Positive Cutter Adjustment, together with the Adjustable Frog make accurate work easy to perform.
The handles are of Selected Hardwood and the Cutting Iron of heat treated Tungsten Vanadium Steel retains its fast cutting edge on the hardest of timbers.
