Ideal for cutting small rabbets or trimming tenons to fit. Based on the Sargent No. 507, this low angle, fixed-mouth block plane has open sides with a blade that extends the full width of the body. It’s a great design, handy as a block plane and wider than most rabbet planes, making it easy to trim tenons to fit.
When set to cut, two circular A2 nickers protrude .010" on each side for scoring cross-grain cuts; The low angle of 12º makes it an excellent choice for end grain. Unbreakable Ductile Iron body ground flat and square to .001". Bronze cap.
The body casting is ground dead flat. Occasional hand lapping with fine wet/dry sandpaper (320 grit or higher) on a flat surface will help remove dings and keep it true. The cap iron can be polished with any good brass polish or allowed to patina with age and use. Occasionally the tool should be disassembled, cleaned and moving parts oiled. The blade should be kept lightly oiled to prevent rust. A light oiling on the threaded rod and Brass adjuster will keep them moving freely. Many people like the patina that Bronze gets with age and use, but if you wish to keep the finish bright, a little brass polish is in order. The blade should be kept lightly oiled to prevent rust, especially when the tool is not in use.
The sides of the Ductile Iron body are stout. However, because the sides are open at the mouth, the “frog” may flex under the blade as pressure is applied to the cap iron via the spinwheel. Very little pressure is necessary to hold the blade, so if you wish to minimize the flex, back the spinwheel off a bit. We have intentionally left the leading edge of the frog section thick for strength. If you ever decide to surface the sole, be careful not to remove too much material. The body is cast from Ductile Iron, a very strong alloy that will take a lot of abuse. These castings are fully stress-relieved, a process that removes inherent stresses and ensures that the tool will remain flat and true. The cap is Manganese Bronze. Other parts are Brass; the adjuster nut is Stainless Steel.
The blade is A-2 Tool Steel hardened to Rockwell 60-62, cryogenically treated and double tempered. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time. After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly. The 1/8" thickness provides solid chatter-free cutting.
