Sorry, our agreement with Woodcraft restricts us from shipping WoodRiver Planes to the U.S.

We highly recommend WoodRiver V3 planes. These planes are based on the reliable Stanley Bedrock design, are very well made, and have an excellent price point making them a "BEST VALUE."  We offer our WoodRiver planes with either our standard “Preparation service” or our premium “Cosmanized service.”  Either way, our planes, unlike the vast majority of planes you can buy, are 100% ready to use out of the box (see below for details).

Traditionally, a smoothing plane is the last plane used on a board's surface to make it smooth.  Smoothing planes have short bodies typically between 8 inches (203mm) - 10 inches (261mm) long.  These short bodies allow the plane to follow any undulations in the board's surface and thus smoothing it rather than planing off the tops of the undulations and flattening the surface like a longer bodied plane would.

Plane Description

  • No. 4-1/2 Plane size: 10-3/8 (272 mm) long x 2-7/8 inches (86mm) wide with a 2-3/8 inches (60mm) wide blade.
  • Heavy, stress-relieved ductile iron castings.
  • Fully machined frog bedded at a 45-degree angle.
  • The frog can be adjusted without having to remove the blade.
  • Thick (.125 inch / 3mm) steel blade and chipbreaker which dampens vibration.
  • Rockwell 58-62 hardness blade.
  • Lightly finished Bubinga handles provide comfort and control.

Plane Preparation Service.  Our plane preparation service makes it so that no setup is required by you. Your plane is ready to use out-of-the-box!  Our plane preparation service includes:

  • Flattening the sole to within +/- 0.0015 of an inch (0.038mm) of perfectly flat.
  • Squaring the sides to within +/- 0.0015 of an inch (0.038mm) of 90 degrees to the sole.
  • Flattening the bottom of the rear handle (tote) and its boss so they mate properly with no movement.
  • Chamfering / easing all edges of the sole of the plane.
  • Tuning the lateral adjustment lever so it moves freely.
  • Applying a back bevel (Charlesworth ruler trick) to the back of the plane blade.
  • Sharpen the blade using micro-bevels. Final polishing is done using 16,000 grit ceramic waterstone.
  • Flattening the back edge of the lever cap so it mates properly to the chipbreaker.
  • Flattening the leading edge of the chipbreaker so it mates properly to the blade.
  • Testing the operation and set-up of the plane.
  • Removing all of the shipping / packing grease and applying a light coat of camellia oil to all the metal surfaces to prevent rust.

Cosmanized Plane Service.  Includes all the elements of the plane preparation service described above, plus:

  • All common screws (frog adjustment screw, frog retaining screws, lever cap screw, and chip-breaker screw) are replaced with hex head screws for positive connection when making adjustments.
  • The blade adjustment knob is replaced with a Rob Cosman AdjuStar for ease in turning.
  • The plane IS NOT pre-drilled to accept Rob Cosman’s hand plane shooting grip as this plane is not appropriate for use on a shooting board.
