I have a pair of H&R that are a bit unusual and I’d like some input about why. This pair of planes was made by Barry & Way, N. York (I’m guessing that’s North York, not New York). I used these as models for some H&R planes I made and blogged about recently. These planes cut a radius of 1/4”. But the round plane cuts more than the typical 60° of arc for H&R planes. The iron is 15/32” wide whereas if it cut 60° of arc, it would be 1/4” wide. So it cuts almost a half circle. The only decent picture I could get of this is an end view. I’m sure different plane makers produced different amounts of arc depending on what the customers wanted. Any idea why this would cut more than the typical arc? The hollow plane is shown in the following picture. The right side of the plane is shown on the right side in the picture, the front of the plane facing the camera. You can see that this plane not only has the hollow profile, but also has an angled aspect on the right side of the iron. The right side has a chamfer and the iron extends into this area. Two questions here. Am I right in thinking that a hollow plane would have no chamfer on the right side – the right side would be flush with the longest aspect of the iron? If this plane has another purpose, does anyone know what it is? Thanks for your time. -- Matt, Northern CA |

That round looks like a side round but not quite and the hollow kind of looks like a snipes bill but not quite. There were always exceptions to the 60 degree standard, my dumb guy guess is that both were simply made for specific profiles. Like here’s a group of simple profiles that would be impossible to make with a regular old standard H&Rs:
Maybe someone with more knowledge can chime in. |
