A powerful tool for heavy stock removal, the No. 7½ Low Angle Jointer combines the length of a jointer with the simplicity and flexibility of a block plane. The low-angle and long base make it ideal for shooting joints and fittings as well as for trueing large surfaces.
It has the same dimensions as our No. 7 Jointer but with the blade mounted bevel up at 12°.
Our Low Angle Jointer is the largest Low Angle Block Plane ever produced. It is as big as a No. 7, but with a much simpler design that is quick and easy to set up, and is excellent for a wide variety of work.
The blade sits in the body bevel up at 12°. It comes with a 25° flat ground bevel, making the included cutting angle 37°.
The blade comes ready to use, but honing a secondary bevel
of 5° or 10° will increase performance, help achieve a razor edge quickly, and improve edge life in hardwoods. You can find sharpening

Blade adjustment is simple, direct and positive. Hold the tool in one hand with your thumb on the cap. Loosen the cap iron thumbscrew all the way, then tighten slightly until there is a little resistance. Adjust depth of cut with the stainless steel nut. Sight down the base of the tool from the front, and judge depth and squareness of the blade by the thin dark line of the blade showing against the sole as it protrudes. When you are done, snug the cap thumbscrew. Do not over tighten.
The Low Angle Jointer intentionally has very little lateral adjustment of the blade. This is an advantage. As you adjust the blade, it will track squarely with the sole. The disadvantage is that you must sharpen the blade square. We recommend our Honing Guide to help with this task. If you find that you don’t like this feature, you can grind the blade narrower to give more lateral play.
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 and Steel and Cherry.
The blade is ¼" thick A2 cryogenically treated tool steel, double tempered to Rockwell 60-62. 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 thick blade provides solid, chatter-free cutting.
The sole is surface ground flat to a tolerance of .0015". Depending on how much use your tool gets, an occasional light sanding with 320 grit or finer wet/dry paper on a flat surface will keep the sole in as-new condition. Tools with Iron bodies should be kept lightly oiled or waxed to prevent rust. We recommend Jojoba Oil, a plant based oil product that is non-toxic, odor-free and easy to use. Also, in our shop, we use a fine abrasive handblock to remove any light surface oxide from tool bodies and blades. Jojoba Oil and abrasive handblocks are available from us.
A light oiling on the threaded rod, the Brass adjuster nut and the lateral blade adjustment lever 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 Cherry knob and handle are oiled and buffed with wax to produce a natural finish. Wipe with oil as desired to refresh.
Materials and workmanship are guaranteed for the life of your tool. Call for repairs or replacement parts. We are available for advice if you ever have a problem using your tool.
Bronze and brass alloys contain lead, a chemical known to the State of California to cause cancer and birth defects, or other reproductive harm. Wash hands after handling.
