Chipbreaker Grinding Guide When grinding the edge of a plane blade, you need a guide of some sort to ensure a straight edge and an even grind. Some aftermarket tool rests include blade-holding j igs that run in a groove in the rest. Alternatively, you can simply clamp to the blade a short wood or metal "fence" that runs along the front edge of the tool rest. However, many typical metal-bodied smoothing planes, jack planes and jointer planes have their own built-in guide of sorts. Simply switch the chipbreaker to the opposite side of the blade and orient it perpendicular to the blade. You can slide the chipbreaker up or down the blade as necessary to create the proper distance from the cutting edge, then lock the chipbreaker in place using its own screw.

If you're not careful when reaching for a board exiting the planer, your fingers can easily be trapped between the end of the board and one of the rollers, causing serious pain. On the infeed side, a board entering the planer can shift sideways suddenly, pushing an errant finger against a roller and a metal side rail. The height of the boards should be lower than the rollers To prevent this danger, I filled in the spaces between my support rollers with boards. Each board is simply screwed in place through holes that I drilled through the metal side rails. Use at least two screws at each end of a filler board, and make sure that the boards are slightly below the level of the rollers.
