N°4 smooth plane

3D Model

Specs:

• The blade is ground sharp at a 25° bevel
• 9-1/2” long. Blade is 2” wide x .125” thick
• Bronze 4-1/2 lbs, Iron 4 lbs

Mouth Adjustment:

• To adjust the mouth opening, loosen the two locking screws at the back of the frog; then turn the middle adjuster screw. Observe the opening in front of the blade. When it is correct, set the locking screws again

Chipbreaker:

• The Chipbreaker is 1/8” thick. The raised lip under the bevel of the chip-breaker is back beveled 1° to ensure that the leading edge contacts the blade firmly.For general work, set the end of the chipbreaker about 1/16” from the cutting edge of the blade; for the finest smoothing work, set it closer to the edge

Blade Adjustment:

• To advance the blade, turn the adjuster nut clockwise. It is always a good idea to finish adjusting the blade by a forward adjustment to take up backlash and to prevent the blade from moving. In order to be able to adjust the blade easily, do not overtighten the lever cap screw.
