Correct angle for a bull-nose rabbet plane (Record 76) blade

Woodworking Asked by 111111 on April 12, 2021

I have a Record 76 rabbet plane.

The plane is bevel side up, and the primary bevels as ground by the manufacturer appear to be 45° or close to it. (If I apply pressure to the bevel whilst bevel side down on a flat surface, the blade seems to "stand" at an angle half way between the surface and the vertical.

Rightly or wrongly, the blade has a secondary bevel ground onto to it. I am not sure of it’s angle, but clearly it must be steeper than 45°.

The plane iron is sharp but when assembled it cuts rather terribly no matter how I adjust it. The blade doesn’t want to "plane" but rather dig in and stall.

So what should I do? My gut says I should grind away at the primary bevel so that it becomes a single beveled iron cutting at 45°.

One Answer

While a 45 degree angle is quite high, this should work. It is common to use higher angles in bevel-up planes to prevent tear-out in more difficult woods (i.e. figured, reversing grain, or difficult species). The higher angle will cause the plane to be more difficult to push, but in a narrow plane like this that shouldn't matter.

There's not really a whole lot that can go wrong in bevel-up planes, but I would check to make sure that the sole is flat, and in particular that it isn't hollow in front of the blade. This will prevent the fibers from being supported before the cut and lead to the wood splitting out before the blade cuts them. This is more of a concern here due to how little support there is for the nose of this plane. (I've previously had a Stanley 78 with this exact problem. It was basically a total loss.)
