The plane is ready for use straight from the box though many woodworkers will prefer to add their own personal honing touch to the cutting edge.
The cutting iron is Hand Forged High Carbon steel which will take and hold an edge better than most contemporary planes! The extra thickness of the cutting iron and of the two piece cap iron gives the cutting edge tremendous support close to the point of cut.
The Frog mechanism is on the BEDROCK principle, which, due to having fully machined full-face bearing surfaces on both the frog itself and the seating pad in the body, again ensures absolute rigidity. These design features give the CLIFTON plane the most rigidly clamped cutting iron of any bench plane currently available.<
The Bedrock design differs from the Bailey design in that the frog is clamped to the seating by means of two dowel pins with "dimples" on their shanks, into which the cone screws (either side of the brass adjusting wheel) tighten. If you dismantle the frog mechanism, ensure that the "dimple" on the shank of the dowel pins faces to the rear/heel of the plane, so that the cone screws can engage. To adjust the mouth width, the frog should be moved backwards or forwards as required; to do this, give a quarter turn to the two outside screws to slacken off and then turn the central screw clockwise to close the mouth and anti-clockwise to open the mouth. Then re-tighten the two outside screws. The mouth is adjustable to a very tight/fine aperture.
Other features are stainless steel screws, dowel pins and lateral adjusting lever (which is also thicker than usual)..... fuIly ground sides ..... and a hefty feel.
The cutter adjusting wheel engages positively - so no irritating "back-lash" appears; and at the time a CLIFTON plane lefts the factory it was flat within the British Standard for Bench Planes of 0.003" (three thousandths of an inch)(0.076 mm). Each plane is checked on a dead flat granite bed with a feeler gauge of 0.003". lt is a well-known fact that castings will "move" with changes of temperature and over the years ..... we even know of a 40 year old plane which continues to "move" .... but CLIFTON has taken ample practical steps to minimise this effect. Nevertheless climatic variation may affect your plane.
Finally, a drop of light machine oil from time to time on the full length of the cutting iron and on the frog/frog seating will keep the CLIFTON plane looking good and performing well.
