| Intro = The jointer does one important thing very well. It creates a perfectly flat surface, either on the face of a board, or on the edge (with the face of the board riding against the jointer's fence). When milling rough lumber, the jointer represents the first step, producing one flat face and one straight edge for reference. The board then moves to the planer for thicknessing and the tablesaw to be cut to final width.

| Intro = A jointer is used to create a straight surface on a wooden board. It can also be used to create a second straight surface at a right angle to the first straight surface.
To work properly the outfeed table should be set at the exact same height as the blades. The position of the infeed table determines the depth of cut, and multiple passes can be taken to produce a completely flattened surface.

* Never edge joint material less than 1/4 in. thick, 3/4 in. wide or 12 in. long.
+
* Never face joint material less than 3/8 in. thick, 3/4 in. wide or 12 in. long.
+
* Always have the blade guard in place.
+
* Stand to one side of the jointer, not directly behind it.
+
* Stand at the left side of the cutterhead -- never stand at the end of the front table, because a board may accidentally kick back.
+
* Keep your eyes and undivided attention on the machine while using it.
+
* Allow the cutterhead to reach full speed before starting a cut.
+
* Keep your hands on top of the work and use a hold down.
+
* Use paddles, push blocks, and push sticks to keep your hands 6 in. away from from the cutterhead at all times.
+
* Never feed material with your thumb or fingers on the end of it; keep them on top of the material.
+
* Always try to plane in the direction of the grain - never plane the end grain of narrow stock (less than 8 inches).
+
* Surface the concave (hollow) side of a warped board first.

* Keep the floor around the machine clean and clear of scrap wood.

Jointer

A jointer is used to create a straight surface on a wooden board. It can also be used to create a second straight surface at a right angle to the first straight surface.

Basic Info

  • Ownership: TBD, best contact person is Dave Alvarez
  • Location: The jointer should be stored in the Wood Shop. It is on a wheeled base so it can be rolled out to provide clearance for working with long boards.
  • What it looks like:

Manufacturer Information

  • Make/Model: Chiu Ting WJT-150 (6 inch jointer)
  • Part Number: S/N 4932

Documentation

not specified

Rules

  • To prevent nicks on the blades, please check your board carefully and remove nails, screws, and any other metal bits.
  • Work with pure wood only, please! Masonite, for example, will quickly dull the blades. Even plywood, particleboard, MDF, and the like will shorten the blade life because of the glue content.

Instructions

Set the cutting depth

The depth adjustment ...

Turn it On

The power switch is located on the front of the base.

Turn it Off

The power switch is located on the front of the base.

Other References

not specified

Maintenance

Two critical adjustments need to be maintained on the jointer. The infeed and outfeed tables need to be parallel to within 0.001 in. or so, and the blades need to be 0.001 in. higher than the outfeed table.

Things that Need to be Done

  • The sawdust chute dumps directly onto the floor. Perhaps a box or a dust collection hose would make cleanup more convenient.

FAQs

  1. What is a jointer? Wikipedia has an excellent article on the Jointer.
  2. Is there an online video that discusses jointer table/cutter alignment? Yes: jointer adjustments
