Wooden 12" jointer plans for sale

12" (30 cm) wide jointers are very expensive and heavy to buy, but small 12" thickness planers can be very inexpensive. These plans are for converting one of these small planers into a 12" Jointer that is inexpensive and light.

This jointer is designed to be buildable mostly from parts of an inexpensive 12" thikness planer and wood. Other than screws, the only metal parts are some 3/8" (10 mm) steel rods, and some 1/8" (3 mm) metal plates to put onto the wooden tables.

The plans include:

  • Detailed drawings of every part of the jointer
  • Dimensioned 3D views and assembly drawings
  • Full-scale 1:1 drawings of all the parts, so you can easily check your parts without the need to measure.
  • Detailed instructions on how to build it, with over 90 photos
  • Materials and hardware list
  • A SketchUp model of the jointer, which allows you to view it from any angle, disassemble it, or regenerate each of the views in the plans by clicking on the 'scene' tabs in SketchUp. SketchUp is a free, easy to use CAD program, downloadable from Google.
