• Hand Tools Planes

2
TYPES OF PLANES

• A carpenter's hand tool with an adjustable blade
  for smoothing or shaping wood "the cabinetmaker
  used a plane for the finish work
• Common types used are
• The Smoothing plane
• The Jack Plane
• The Block plane
• Spokeshaves for curve work
• Electric Hand Plane

3
THE SMOOTHING PLANE

• Is typically 8 to 10 inches long, has a tight
  mouth and is held with both hands.
• The iron of the smoothing plane is generally
  sharpened straight across or with a slightly
  arched cutting edge

4
THE PLANE (Nomenclature)

• The depth of cut is set by turning the Depth
  adjustment knob found behind the blade, try for
  fine thin shavings, making several light cuts

5
THE PLANE (Nomenclature)

• A The Mouth is an opening in the bottom of the
  plane down through which the blade extends, and
  up through which wood shavings pass.
• B The Blade or Iron is steel with a sharpened
  edge which cuts the wood.
• C The Lever cap holds the blade down firmly to
  the body of the plane.
• D The Depth adjustment knob controls how far the
  blade extends through the mouth.
• F The Cap iron makes the blade more rigid.
• J The Frog is a sliding iron wedge that holds
  the plane Iron at the proper angle. It slides to
  adjust the gap between the cutting edge and the
  front of the mouth. The frog is screwed down to
  the inside of the sole through two parallel slots
  and on many planes is only adjustable with a
  screwdriver when the plane iron is removed

6
JACK PLANE

• Is the general-purpose bench plane, used for
  general smoothing of the edges and sizing of
  wood. Jack planes are about 15 inches long, and
  the blade usually has a moderately curved edge.
  In preparing wood, the jack plane is used before
  the smoothing plane.
• The name is related to the saying "jack of all
  trades". Jack planes perform both the work of
  smoothing planes and trying planes

7
Block Plane

• A block plane is a small woodworking hand plane
  which typically has the iron bedded at a lower
  angle than other planes, with the bevel up. It is
  designed to cut end grain and is typically small
  enough to be used with one hand.

8
SPOKESHAVE

• These handy tools come with either straight,
  convex, or concave blades, they are an excellent
  tool for hand shaping material.
• CONVEX CONCAVE

9
ELECTRIC HAND PLANE

• A blade revolves at high speed and as the machine
  plane is pushed across the surface of the wood -
  it is planed.
• A big disadvantage of these planes is that they
  are potentially very dangerous if misused. Also,
  sometimes the finish to the surface is not as
  smooth or precise as a hand held plane being
  carefully used.

THE PLANE (Nomenclature)

1. The Lever cap holds the blade down firmly to the
   body of the plane
2. The Blade is a plate of steel with a sharpened
   edge which cuts the wood.
3. The Cap iron makes the blade more rigid
