The jointer is designed to quickly and accurately accomplish many operations that would require many hours of tedious labor if done by hand. It's a rotary cutter that will plane edges smooth and square, ready for gluing or assembling. It will do a fine job on light surfacing cuts also, but should not be confused with the planer, as jointers often are. The planer is designed to dress stock to exact thicknesses and perfectly parallel surfaces. The jointer is used to square edges to surfaces and straighten surfaces.

Setup and Features

Figure 6-1. The Jointer can be mounted on (A) the MARK V or on (B) a Shopsmith Power Stand.

To set up your jointer, follow the instructions in the Owners Manual that came with your jointer. As you work with the jointer, you'll find that it has several special features:

  • The jointer mounts on the Mark V or a Shopsmith Power Stand (Figure 6-1).
  • The dust chute will allow you to connect the hose from your dust collection system to the jointer. Since most heavy-duty dust collection systems have fairly strong motors, you should not plug a dust collection system into the same circuit as the Mark V.
  • The width of cut is a full 4".
  • The depth of cut is adjustable from "0" to 3/8". The maximum depth of cut for most operations is 1/8". When surfacing, the maximum depth of cut is 1/16". You can make full use of the 3/8" depth of cut in stages when performing special operations.
  • The infeed table is 5-5/8" wide by 13-1/4" long. The outfeed table is 4-1/2" wide by 13-5/16" long. Together, the overall table length is 28".
  • The fence is 3" high and 21-3/4" long. It tilts 45 to either the left or right and has adjustable positive auto-stops at 45 right, 90, and 45 left. It may be positioned anywhere over the cutterhead. Also, the fence has predrilled 1/4" holes, making it easy to add fence extensions to help support wide stock.
  • Figure 6-2. The cuts and shapes listed here can be formed on the jointer. (A) chamfer; (B) tenon; (C) bevel; (D) taper; (E) edge rabbet; (F) end rabbet; (G) surfacing (cut depth exaggerated for clarity); and (H) furniture let (example). Click on image for larger view.
    The cutterhead is 2-1/2" in diameter, with three precision-ground steel knives. It's equipped with individual knife leveling screws so that you don't have to match-grind each knife.
  • The jointer can make the cuts and joints shown in Figure 6-2.
