My experience with wood... well, it's like this: I have a good amount of experience in cutting down trees, and in sawing dimensional lumber. But as far as finishing wood goes, my experience is virtually zero. I've made a few tables and things like that over the years, but I've never applied myself to anything like a really nice walking stick, except for one I made last year. That one came out ok, but after reading some of the posts here, I'm now considering doing some carving on it.
Now about making a shillelagh from almond, I'll probably take off the bark. I don't think it would stay on the round anyway, since almond bark comes off pretty easily by nature. I do think I can find a stick suitable for a good shillelagh without too much trouble. But again, after some of the posts here, and after seeing those pics, now I'm thinking of making a nice cane.
The thing about almond wood though, is the many knots. Generally, to get really good heartwood you need to go to the stump, but these are usually too short for a walking stick, so the next choice is the first limbs growing out of it. These limbs are usually long enough, but lots of branches are usually present. Besides, the limbs are too big around, unless someone wants to turn them on a lathe.
So the next choice are the secondary branches, which sprout from the limbs. Here is where I would find my shillelagh, because the stick's diameter would be about right, and I could use the wood where it's cut from the limb as the mallet end for the shillelagh.
These secondary branches have lots of other, smaller branches coming out of them, so it might be kind of hard to find material for a cane without too many knots. There are different varieties of almond trees, some bigger than others, and a few get pretty large. But these very large trees are not the norm. Most of the trees around here just aren't that big, so finding a stick that is long enough, without too many knots, suitable for a can might be kind of tough.
It does occur to me though, that I might be able to find the perfect stick from the roots. Here's where I would ask for advice: can root stock be used for a walking stick? You see, almonds have a very shallow root system. They grow well in sandy loam. When orchards are removed, the typical process is to cut down the trees, then rip the stumps out of the ground with a tractor. One company here even developed a machine that rips two trees at a time, simply by driving their tractor between rows of trees.
The root ball is very thick, but it's not uncommon to see nice branch-like roots radiating out in a fairly straight fashion. What I don't know is how hard the roots are. I just don't have any experience with these, other than watching them being ripped out of the ground.
