So I recently purchased a matching set of plow plane irons made by W.M. Ash. The idea was to either make a new wedge for my existing plow plane, or perhaps get crazy and make a whole new plow plane. There isn’t anything wrong with my current plow plane (except for a stripped depth stop screw), but I only have a 1/4″ iron for it.
Plow plane irons can be kind of funny though. Because of their shape, the plane and wedge are typically made with a matched set of irons. Irons from another plane may not necessarily fit because of differences in tapers. Of course one can compromise by making different wedges for each iron if you have a mixed bag of makers with different tapers, but I didn’t want the hassle. I wanted a matched set of irons.
So I got them today, and just for giggles, I pulled the current 1/4″ iron out of my plow plane. Guess what? The iron that came with the plane is a W.M. Ash iron with an identical taper. I tried all of the “new” W.M. Ash irons in the plane (made by Bensen & Crannell) and they are a perfect fit. So there won’t be any need to make a new plane or a new wedge. Perhaps I’ll just carve a new depth stop screw (and perhaps I won’t since I have grown used to just planing to a scribe line anyway). So now I have two 1/4″ W.M. Ash plow irons.
It doesn’t happen often, but it’s nice to catch a break once in awhile.
