SPEAR AND JACKSON CSP3 Smoothing Plane

Blade Sharpening

• For best results, the blade (sometimes otherwise referred to as ‘the cutter’, or the iron) on this product requires sharpening prior to use.
• This requires removing the blade by turning the brass thumbscrew anti-clockwise on the iron cap (sometimes otherwise referred to as the “lever cap) (fig 1).
• Unscrew the cap iron screw until loose and remove the cap iron from the blade (fig 2).
• This product is supplied with a blade ground angle of 25° and should be honed to 30° (fig 3).
• Use thin machine oil to lubricate a flat oil stone and place the 25° bevel flat on the stone, raising the blade 5° to the 30° honing angle.
• Using a figure of eight movement to distribute wear evenly, sharpen the blade.
• Once a burr has formed at the edge of the blade, turn it over and re-position the cutter to sit flat against the oil stone with the bevel facing up. Gently sharpen to remove the burr.
• Ensuring the cap iron is parallel to the blade, re-attach the cap iron to the blade and tighten the cap iron screw (fig 4).
• Place the re-assembled blade into the body of the plane and secure the lever back into position.

Quick Tips

• The brass adjusting nut can be used to alter the depth of cut.
• When planing softwood, set the cap iron 2mm back from the cutting edge.
• When planing hardwood, set the cap iron as close as possible to the cutting edge.

For Best Results

• Keep shaving thickness to a minimum.
• Ensure that the plane base is maintained in line with the workpiece.
• At the start of the stroke, apply pressure to the top of the plane. Adjust this pressure to the heel of the plane towards the end of the stroke.
• At the end of each cutting stroke, lift the plane from the workpiece before the next stroke.
• This product should be used to plane in the direction of the wood grain. When planing end grain, work from edge to middle.
• Candie wax can be used for ease of movement if required; simply rub the wax into the base of the plane.

Product Care

• Keep the blade sharp, and oil metal parts when not in use.
• Do not use other metal objects to clear shavings from the plane.
• When not in use, lay the plane on its side to protect the blade.
