Lumber from Logs II -- heavy artillery

The ultimate weapon in the backyard lumbermill arsenal is a bandsaw lumber mill. These are major machinery; even the cheapest one (new) will set you back several thousand dollars. (You can google on bandsaw lumber mill and get torrents of information.)

For those of us who cannot justify such an expense, there is always the Alaska Chainsaw Lumbermill. Granberg's Alaskan Mill is a neat gadget. It costs money, but is cheap at the price. It is basically a steel frame that carries the chainsaw as you rip.

The first job is to set up a frame of wood or metal, place it on the log, and even things up.
The frame is a 2x4 structure nailed up from commercial lumber. I abhor commercial lumber, but sometimes one must swallow one's scruples to progress. (Politicians do this as a way of life.) Having done this you nail or screw the frame to the wood, being very careful where you place the nails. You do not want to run the chainsaw into a nail.

Next, you set up the mill, following the rather terse directions that come with the mill. (See Granberg site, above). The mill rides on the platform you just set up. If it is straight and level, the chainsaw will be likewise. So you take a full cut, and rip off a slab.You now have a nice neat surface on the log. The chainsaw rides on that surface for the subsequent cuts. Actually, for my first cuts with this contraption I used a piece of power pole, kindly provided by Matanuska Power when they replaced a pole, and I got a few 25mm (1") boards out of it.
I am sitting on the slab I just ripped off (literally). The power pole turned out to be either cedar or redwood. It is much easier to rip cedar than it is to rip birch.

Looks easy, doesn't it? It's not. First, in ripping the big stuff, you need a big chainsaw. I used my largest, Siegfried the Stihl, with a 50cm (20") bar, all of 61cc or so. It is up to the job if you don't force it, but just. The saw roars, and it is going full ahead all the time. When you crosscut, the saw is loafing for the top and bottom parts of the cut. Not so in ripping.

The sawdust outlet on saws is designed for crosscutting, so when you have the saw on the side, it comes out right in your face, along with the exhaust. Protective gear is mandatory. The stuff is heavy. But it makes very nice boards.

The ultimate book on chainsaw lumbermaking is by Will Maloff, and it is out of print. Mr. Maloff has a website; Will Malloff-working with wood. Mr Maloff advocates a 120cc (or more) saw, along with meter-plus length bars. Another unjustifiable expense. But if I was cutting up the monster trees that he does, I'd have to do it or pass up the lumber. See his website, and look at what he's ripping up.

Squaring the circle, or lumber from logs

In Alaska, we have a paradox. While we are surrounded by trees, lumber is very expensive. This is because it is imported from the "lower 48," as we call the rest of the USA (except Hawaii). There is enough lumber -- spruce, anyway -- to go a long way, but for various political reasons, which I will not rant about now, it is unavailable; when it becomes available it is in some remote location. Okay, this is a challenge. I want a workbench for metalworking projects, so I decided to build one, from logs that grow on my property or I find lying around on the power line right-of-way , for instance. The wood of choice is birch, because it is a hard(ish) wood. If the scandinavians can build things out of birch, so can I. There is nothing but birch, spruce, alder, and aspen in this part of Alaska.

The traditional way to do this is by hewing the log. You outline the square you want on the end of the logs, snap chalk lines to indicate where you want to cut, saw down to the chalk line, and then chop (hew) out the stuff between the cuts. A picture may be in order:
Here it is spring 2008, and I am hewing out the cuts I made with a saw. I am using an adze to do this. Some say a broadax ( a one-side-edged axe) is easier. But broadaxes are only made, as far as I know, in Sweden, where this kind of thing is considered an art form, and they are very pricey. Well, this makes quite a decent log, but it takes a long time! It is also tiring, me not being as young as I once was. So, when I finished that first log, I went to plan B. Let's see if we can do it with a chainsaw, freehand:
Above, I use an (electric) chainsaw to slab one of the crosspieces. This is much hairier than the adz, because a chainsaw is a dangerous tool, but it takes minutes. Does it work? Glad you asked.
The surface leaves much to be desired, because the chain is a crosscut chain, and I am ripping -- going down the grain. (I have since acquired a gas chainsaw that has a very narrow bar, and it leaves a much better surface.)

Here is a finished crosspiece:
I happen to think that the picture above is a rather nice still life. By the way, the workbench in the picture came up with me from Juneau. I built it entirely out of found wood, at a cost of $8.00 US for fasteners (bolts to hold down the top. There are no screws, nails, or staples in that bench, and there will be none in the new bench).

The third option in lumbermaking is the heavy artillery option, but I'll leave that for another post.

El conuco, part I of many

Conuco is a Venezuelan word, derived no doubt from the Carib language, which translates to "vegetable garden." However, a conuco has many connotations that are usually not associated with a veggie garden. It implies rough and ready, rural, and not, perhaps, up to the latest agronomical standards. So I began to garden in 2006.

In another lifetime, in Maryland, I had tried gardening, but it was difficult. The rabbits, for example, ate most of my garden before I could do the same. My neighbor had no such problems and produced agricultural wonders from 50 meters away, but then, he had a green thumb, among many other talents. Fast forward to 2006. There was a place on my land where I could see beds through the weeds, so I took my trusty garden fork and dug up the weeds. It was a major workout.
At the time, I did not understand the meaaning of "sod" -- the collection of matted, snarled plant roots that underlies anything that hasn't been gardened for a while. I suspect my predecessors didn't garden, and that the rows date back to antiquity, or anyway back to 1985 when the house was built.

So I cleared out four meters of junk from the rows. As I say, it was hard work, but strangely satisfying. The result was conuco, v1.0. Four meters of garden.
Knowing I was going to have a garden, I had started some lettuce in containers previously. You see me above after I transplanted the lettuce. Four meters of lettuce is enough to feed the entire russian village, let alone me, but I didn't know that at the time. We learn from our mistakes. But at least I had some rows dug.

Do you know, stuff actually grew, not only in the garden but in the greenhouse.
All that lettuce. Wow. The greenhouse wasn't too tacky either:

I don't know what ws greener, me or the garden. But we had some good results in a few areas, for instance cucumbers.
I don't think we had ripe tomatoes in '06. But then, I can't remember having ripe tomatoes ever. Since then, we have swung over to the "cold cycle" of the North Pacific Oscillation (NPO) and without heating, I doubt that I will see ripe tomatoes at Chalupy. We keep trying, though. It is really hard to garden in Alaska, because the season is very short, basically Memorial to Labor day. I have seen frost two days after Memorial day. On the other hand, the long daylight hours mean some crops (cabbage, for instance) achieve gigantic proportions. At last year's State Fair, one cabbage weighed in at 83 lb, about 40 kilos. It is probably quite inedible.

So on the whole, it was progress. I had lettuce galore, some cukes -- I was happy, anyway.

A greenhouse grows at Chalupy

Still in 2006, come spring, it was time to build a greenhouse. Now in Alaska the classic way to build a greenhouse is with "PVC flex and visqueen", i.e. flexible PVC piping and trasparent, or at least translucent, plastic. This gives you what has come to be called a hoophouse. But my objective is always to buy the minimum, so for version 1.0 greenhouse this was the playpen that came with the house. Pole construction seemed the way to go, so my first step was to take a walk in the woods and collect some poles.

Onece I had some poles, came the task of peeling them. This is not a pleasant job. These poles are too long for the shaving horse. So I improvised with a forked stick.
The reason you peel is to avoid the wood rotting on you. The inner layer of the bark (the cambium layer) is basically bug food. Leave it there, feed the bugs, rot the poles.

As you see, the trusty drawknife works well for peeling poles. Note the snow on the ground, it was in April, I think. With some peeled poles, I blocked out a crude shed to fit the old playpen.
There were many frustrations which I won't detail. But slowly the greenhouse takes shape.
The structure you see there survives to this day, and cost $0.00, not, of course, counting labor, because I pay myself no salary.

The last task was to cover it with "visqueen" or translucent plastic. When you buy the stuff at Home Despot, er, Depot, or wherever, it says "transparent." Nonsense. But when you do it, you have a Greenhouse. It ain't heated, of course; it would be more properly called a "giant cold frame." So then it looks like this:
The cost has risen, of course, because I can't make the plastic. We are now into $5.00 for the plastic, a figure that is steadily rising with the price of oil.

So now you are wondering (and quite properly, I may add) whether this contraption works. Well, actually, yes.
Here we have zucchini and cabbages busily growing. I have since discovered that while zucchini belong in the greenhouse, cabbages do not. But that is another story. My life is a long struggle to optimize greenhouse crop allocation.

Greenhouse 1.0 had many faults, but the worse one is that in winter, the snow loads it down (we have a full meter of snow at Chalupy) and the roof collapses. We are now at v1.3, and all of the versions have been concerned with not having to rebuild the roof. So far the score is winter-3, JRC-0. Looks bad for the home team. But there is always v1.4. And we have plans for v2.0, but I will not reveal them because this is what we call in Venezuela pavoso, jinxing the outcome.

As I write, greenhouse 1.3 is full of tomato plants and some cucumbers. Will they ripen? We shall see. It is raining, and has been for two weeks. The tomatoes want more photons. Not so many photons, not when it rains.

Green Woodwork

We now go back in time, to AD 2006. In the spring, I discovered a wonderful book by Drew Langsner, who has a very nice web page, Welcome to Country Workshops, with many goodies. The book is called Country Woodcraft, ISBN 0-87857-201-5. Unfortunately it is out of print, but still available on the secondhand market. It goes a step further than Roy Underhill's books; Roy too has a website, The Woodwright's Shop.

Both these gentlemen work wood the old-fashioned way, with hand tools. While I have nothing against power tools, I enjoy the quiet, the lack of noxious sawdust, and the lack of noise that you get with hand tools. It seems much more appropriate for Chalupy than screaming table saws. I do have some power tools and use them when I have to, but I prefer the peace and quiet. Time? I have all the time in the world, so I take it.

Anyhow, Drew is big on green woodworking. You find some trees in the forest and use them before they are dry. (But they will warp! you say. Yes, but that is overcome by drying carefully after the wood is worked, and by putting on the finishing touches once it's dry.)

There are perhaps fifty or a hundred projects in Drew's book. Summer of ought-six I built several:

In the front is the birchbarrow, version 1.0. This is a wheelbarrow, of course; I used a bicycle wheel (which I got out of someone's trash) as the main ingredient and built the barrow around it. You may also see the sawhorses, in use to this day (alas --one leg on one of those broke the other day. Winter is hard on sawhorses. Fortunately, as with shaving horses, spares are no farther away than a walk). I am holding a very large mallet called a commander, useful for driving stakes and posts (and perhaps for some moral persuasion of obdurate characters). I have since changed the wheel arrangement to use the original bike fork (v1.1) and now must rebuild the whole front, because it is too tippy when you load it with firewood. This is not Drew's fault, but mine, when I converted absurd gringo inches to metric. I put the wheelbarrow to immediate use.


It hauls veggies (above), firewood, sacks of manure, and almost anything else. It started to turn black, so applied common household bleach and that took care of the black. Birchbarrow is due for a version release (1.3) but I don't think I'll have time for it this fall.

Funny about so much work with software; we have these absurd-looking version numbers, whatsis 2.1.4. Why bother? Because there's always room for improvement, that's why. Most things at Chalupy have version numbers. The British had the same thing going with Roman numeral "Marks," so we had Spitfires Mark VII, which were presumably better than Mark VIs.

Lysander IH tractor, the hero

Life at Chalupy was fine, but I decided I needed a tractor. It could pull wood out of the forest for the fireplace (which I didn't have at the time), it could help me garden, it could plow snow, in fact, it would be a very handy contraption, even if it is YAICE (Yet Another Internal Combustion Engine). This is a weighty subject. I wanted a small tractor -- a Ford 8N, say, or an International Harvester (IH) Farmall A, or a Farmall Cub. (To placate any irate brand-tractor fanatics, I would have taken a Deere, a Case, a Minneapolis-Moline, Oliver, Massey, Fordson Dexta, etc. ad infinitum ). What Craigslist turned up, at a price that I could afford, was Lysander.

Above, Lysander on a field in Palmer, Alaska, home of the Alaskan small farm. I should say something more about that, but not now. Short form: I bought Lysander abd some good friends helped me haul it 60 Km north to Willow. Then I had to drive the thing off the trailer.

Notice the expression of mixed delight and terror on my face. After all, I learned to drive on farm tractors. But that was a long, long time ago, at APISA, the Rivero (and others) owned farm in Venezuela. But I did it!

Lysander was promptly put to work. Here he is after plowing snow.

Since that day, Lysander has been a constant companion. He was built in 1947 and he has been working ever since. He starts immediately, runs like a champ, and has done all that I asked of him. he has a few glitches, for example he won't chage the battery. I am working on that. You say he's rusty. Not so, as you will see. It's not rust, just old paint. Just wait, you will see the paint saga. The only trouble is that he is too big for a lot of the work I do; the H was a mid-size tractor in its day. Amazingly, you can buy spare parts for him. Not at all bad for a 60-year(+) old tractor. A true hero.

Shaving horse, Part II

You can't go to the hardware store and buy a shaving horse. You have to make it yourself. Some people use dimensioned lumber. This would be OK, say, in Juneau, where in spite of being in danger of getting a tree on your head, you can't cut any. I will not, at this time, go any further on that one. But at Chalupy, we have wood in the round, as in trees.

So I found a biggish birch near home. Much too heavy to move; I tied a rope to it and used the car to drag it home. Then I proceeded to split it.

Looks easy, huh? You use wedges, those steel black things at the top of the rightmost log. You drive the wedges with a maul, the yellow-handled monster in the picture. The steel wedges are helped out by big wooden gluts -- one is sticking out of the lefthand log. If you don't have any gluts, you must stop and make them. I didn't have any. Getting to this stage took at least two hours. The bigger the log, the harder it is to split.

Nest you take the better (right) half of your split and you split off the lower part, making a plank out of your log.

If you look really carefully, or maybe have a full-size picture, you can see a blue chalk line which is where I wanted to go. The log didn't cooperate. Tough. That was a nasty log. I am now at least four hours into this project. So now I have to hack the log to shape. Roy Underhill's book suggests you use an adze. My adze at that time was a Portuguese one-handed adze called an enxo', observable in the bottom middle of the picture, and with it I hacked the log to plank shape. All this is an excellent workout. Unlike a gym, you have something to show for it when it's done. Real logs are not straight-grained oak, which splits like a dream; they have knots, burls, twists, and all kinds of obstructions. Con estos bueyes hay que arar, as they say in Spanish -- with these oxen we must plow.

The next step is to put legs on it. This involves drilling some great big holes, then getting suitable legs in thiose great big holes. Unfortunately, drilling great big holes is my bugbear. I can't find a suitable auger. I should mention that for green woodworking, power tools are anathema. Any moron can build anything using power tools. (I will make some exceptions for chain saws, and a few other things. But basically Chalupy frowns on power tools.)

Then we hack out the riser and ramp from out leftover logs. I wish I had some pictures of this, but I didn't take any. Too busy hacking.

The current incarnation of the horse is below.


The top crossbar was hacked out this morning, 'cause the old one broke. One nice thing about a shaving horse is that you make your own repair parts. The strange object that looks like a giant demented comb is, in fact, my bull rake project (as if I didn't have enough projects). But that's for later. In the meantime, I am shaving out the tines of the rake on the horse -- a beautiful way to spend Thursday morning.
