The December 2013 issue of Popular Woodworking Magazine recently came out. In this issue, I wrote a piece for the Arts & Mysteries column in which I talked about choosing woods based not just upon their looks, but for the application and the ease with which they are worked. Well, on the heels of that article, I’ve recently found myself working with a couple of kiln dried species that I specifically suggested be avoided if possible, ash and hard maple. Working with these two kiln dried woods has reminded me once again why I typically try to avoid the dried versions of woods this hard. In my defense, they’re intended for very high stress applications, so I need their rigidity and strength. However, that doesn’t make them any easier to work with.
Some time back, I timed myself ripping a 40″ length of a 4/4 board of black walnut. It took me about 2:00, give or take. For a similar sized piece of white pine, I’d expect it to take about half that long. For this similar length of 8/4 hard maple, it took just over 13:00. Same saw; same sawyer. But it took almost 7 times as long.
You may have seen the podcast “Flat & Square” where I timed myself facing a piece of walnut about 10″ wide. It took about 5-1/2 minutes to surface one side of that wide board. The maple, again, took about 13:00, for a face a bit longer than the walnut board, but about 1/3 of its width. Once again, same tools, same craftsman, much more difficult material.
Finally, there’s the mortises. Two 3/8″ thick through mortises in 3″ hard maple. Let’s just say they took a bit longer than the same sized mortise in pine. The Ray Iles mortise chisel worked like a champ though. It was ready for more after these two maple mortises, no sharpening required.
The mating double tenons took much longer as they had to be much more precisely fit since maple does not compress nearly as much as a softer species. After some paring here and there, they were finally “persuaded” into position.
The final result was certainly worth the extra effort, since, as I mentioned, these are high stress items where rigidity and strength were much more important than workability and appearance. But working these timbers made me ready for a nice piece of Eastern white pine.
