During their most productive and diverse years of hand plane manufacturing, Stanley made several different variations of weather stripping planes. I guess before hand held electric routers were popular, and access to heavy machinery like shapers was available, craftsman used this type of plane to cut narrow grooves in window sash specifically to accommodate weather stripping. If you’ve been reading along, just a little while back, I mentioned that I was currently engaged (and still am) in a window sash project at my house. Since I’m at my own home fixing/replacing the sash on my own windows, I have the benefit of a shop that’s full of heavy machinery. My window sash project does involve cutting a groove the length of both stiles and both rails that will accept a piece of weather stripping. For purposes of time and given the amount of parts that I need to constantly make, I have a small router table set up and dedicated to the task. Outfitted with a 1/16” thick slot cutter, I can make those grooves pretty quickly. Yesterday while I was out in my shop plugging away at my sash project, I got to thinking about how different things might be sixty or seventy years earlier. Maybe I’d have a table saw to help me. Would I have had two? Probably not. Would I have had a shaper? An electric router? Hard to say, but again, probably not. For a craftsman of that bygone era, who was employed to fix one or two windows at someone’s home, lugging around heavy power tools probably didn’t make sense. Thinking in those terms, suddenly it’s much easier to see how a weather stripping plane may have been a necessity for various tradesmen. If one visits certain websites dealing with old hand planes, weather stripping planes tend to get a negative rap in terms of their usefulness and utility. Although they may not be as well known today, or as efficient when making multiple parts, they had their place back in the day. For any craftsman who went to a job site for purposes of repairing a window or two, they were the ideal specialty tool.
Stanley #238:
This plane was manufactured by Stanley between 1928 and 1938. It’s very easy to use and as one can see, it does a very respectable, neat job of cutting grooves for weather stripping. The #238 includes several features that are common to other “plough-like” planes such as a fence and depth stop. The #238 also employs a relatively unique method of securing its various sized cutting irons. The irons fit into a milled groove on the main casting, and slides back and forth in the groove to adjust the depth of cut. A light pass seems to produce the best results. Once the iron is positioned at the desired setting, it is held in place by the shoulders of two screws that pinch it (the iron) down into the groove of the main casting. It’s a little tedious to set up, but not too bad, and the iron does not move once the screws are tightened down. The fence is adjustable on rods that are threaded into the main body of the plane. Notice there are two other rods that are connected to the fence, but not to the main body casting. Those other two rods can be adjusted toward the main casting or away from it and then secured into position with screws. By setting those rods in a desired position on the fence itself, a secondary, repeatable fence location can be achieved. It’s a nice feature if two pieces of parallel weather stripping were used on the same piece of window sash. Also notice how those secondary rods have a piece of wire wrapped on one end to keep them from sliding out of the fence when they’re being adjusted.
The #238 works well as designed, but like many other planes that Stanley manufactured, it had several little parts and seven different width cutters ranging in size from 1/8” to 3/8” that could be easily lost. Most of the irons that I’ve seen have their respective sizes stamped on their sides with a Stanley trademark stamped on their opposite side. Prior to adding a #238 to your hand plane arsenal, do your homework and know what to look for. Make sure all the original/correct parts are present and accounted for. Some of the parts can be extremely difficult to locate separately. Most particularly the fence, the secondary rods with the wired ends, and the individual cutting irons are easy to misplace and expensive to replace…. if one can find them. Very often, the only iron that comes with originally equipped multi iron planes such as the #238, is the iron that was last used with the plane. Any weather stripping plane is probably not one that I’d recommend as a “must have” to use. Electric routers, shapers, table saws, etc. can get the job done pretty quick particularly if several parts need to be made over and over again. But for the one little job, or maybe for some straight inlay work, a plane like the #238 might be fun to tinker with.
