With a 12 degree block plane you must use almost no back bevel. To get a 30 degree included angle, you will need to put all of that on the front. The resulting cutting angle will be around 42 degrees. When honing a blade with no back bevel, you must hone the front bevel using your coarsest abrasive until you have removed all the back wear, then continue as usual with the next two front.
I have just cleaned up my number 4 plane and decided to sharpen the blade. I used my trend sharpening system and ground a 30 degree and then a 25 degree like a chisel. I suspect this is wrong and would appreciate any pointers. Grind at 25, hone at 30 has worked for a lot of woodworkers, for a lot of years, for both planes and chisels. You're fine.
A low angle block plane does a number of jobs on any given project, from smoothing end grain to creating chamfers. Its small, fitting into most apron pockets. This particular model is not the lightest weight model but the additional heft provides some additional inertia. The fit and finish is good and like most planes, it will still need a bit of tuning before using it. The iron is sturdy, and.
An acute bedding angle, finely adjustable mouth opening and top-quality fit and finish combine to create a block plane that makes quick work of adjusting miters, joinery and fitting doors and drawers.

Tips for Selecting the Right Angle To Sharpen Your Knives. Selecting an angle for your knife edge is an important first step in sharpening. Selecting an angle is probably one of the easiest steps in sharpening, once you know the basics. To make it easy, a 20 degree bevel angle is a good starting point. If properly sharpened, the 20 degree angle.
A standard bench plane uses the blade in a bevel-down orientation, with a chip breaker and cap iron (I prefer standard angle bench planes over low angle bench planes, except in block planes). Thus, presenting the back of the blade to the wood. The angle at which the blade is presented to the wood is called the cutting angle or angle of attack. With a standard bench plane, the cutting angle is.
