New Birch Skis

These skis are loosely based on a find from Reinheimen in Norway. They are of birch (Betula pubescens) and may or may not have had fur on the underside. I opted for not using fur as of yet, although I might add that at a later point as is does provide a lot of traction and reduces speed downhill.

The bindings area is where the skis deviate most from the original. The front portion is a rectangular on these skis, and pointed on the original. The hole on mine are also rectangular, due to being chiseled out, whereas the originals might have been carved out with a knife and are more eye shaped. The holes on the originals are probably also a bit more roomy as I could not wrap the withie part (also birch) around twice, which would have made the binding stronger. The buckskin bindings have been threaded through the hole and pegs rammed in in order for the fit to be tight.

Snow conditions are currently pretty horrible as the snow is crusty, wears a lot on the skis and is dangerously fast. The Saami had specialised skis for such conditions, which I might make at a later time. These skis are harder to use than modern skis as they are not completely fixed onto your foot, however with some practice I think it will not be an issue.

I will probably make another pair of these at some point and actually make a tutorial about how to do it.

Splitting Planks 5: Hewing the Boards

When you have split your log, whichever method you want to use, by high likelihood you have to hew the planks, maybe both to thin and straighten them. There might be the rare tree which will split true right away, but hewing still gives a nicer finish.

The log used in this tutorial was not particularly straight splitting and I ended up cutting some of the end off to avoid taking out the spiral all the way. Also, it had a few large knots, which can be pretty annoying.

IMGP1147

First stage is to start taking out the twist as much as you can on one side. Since it will not matter to my intended project if the planks taper a lot, I took most off at the top end first.

After I had a reasonably straight line chopped there, I estimated how much I had to take out on the other side to straighten the inside of the board. This can be done very accurately with string and a weight, but I did not go through that trouble and simply went by eye measurement. I ended up with a very slight twist in the plank, but that should not really be a dealbreaker in this case.

IMGP1152

When both sides were straightened enough I chopped away the centre, being careful to not new a hollow and preferably not make it convex either. The plank was smoothed a fair bit through pushing the axe instead of chopping as it gives more control. Scotch pine (Pinus sylvestris) is very soft and will generally be very easy to shape through pushing. More so with fresh wood than dry wood.

When I was satisfied with what will become the inside of the building, I started chopping out a line on either side of the board to mark out about 1.5 inch thickness over the whole plank.

IMGP1165

Next the remaining ridge was chopped into in short intervals and the pieces split off.

IMGP1172IMGP1176

Final hewing is then done to remove the roughness and create an acceptably smooth surface. For my project, this side will not be visible on the building and I did a rougher job than on the inside.

The whole process takes about 3 hours, depending on length of the board and how straight it is.

Splitting Planks 4: End Splitting

There are several methods for splitting logs for planks and this is probably the simplest one. It requires very straight splitting material if you are going to get long pieces, since you will have to take out the twist with the axe afterwards. For shorter boards it can be very twisted and it still will not matter much. An advantage with this method is that it if the material is very straight splitting you can get several boards out of one length.

A bit about the wood. Scotch pine (Pinus sylvestris) splits best from the top end. Norway spruce (Picea abies) splits best from the base end. Why it is like that I don’t know, but it is certainly the case.

The first part of the process after felling the tree and sectioning it into a desirable length is to use the axe and a mallet to drive in the axe in a straight through the pith. This is done to crack the wood enough to insert the birch wedges.

IMGP1128

The birch wedges are then driven in as far as you can, which should already cause a very significant split. On shorter pieces it might be enough to split the entire length.

IMGP1131

Further splitting is achieved through driving more wedges into the side cracks that develop from the end split. You can do it from only one side, but often it is better to do it from both sides.

IMGP1133

When it has split through you are ready to hew the pieces, which will be shown in the next tutorial. If the piece is particularly straight splitting you can split it again, which will give you an extra board and less work in hewing the original piece. Sometimes the outer piece will run off to the outside though and not follow the whole length. I always prioritise some additonal thickness on the inner piece, since it will be the wider and better board. This is to ensure that the split doesn’t run off towards the inside.

This project was done in collaboration with Jon (http://jonsbushcraft.com/).

The Importance of Fishing

IMGP0935

The ecological information I am writing here is not necessarily true everywhere, but certainly true in this general area. If it does not apply to where you live, just see it as a different perspective. It might also not apply to every type of fish.

The brown trout (Salmo trutta) is the most common fish in this area of Norway. It is in virtually every lake. One could claim it is not natural in the normal sense, since the fish has been planted there in most of the lakes. However, the transplanting goes way back and some of the lakes might have been colonized by the aid of humans thousands ago.

Because it is not strictly natural as such, imbalances tend to occur. In former times we also had bears and otters which might have made a significant contribution to keeping the fish populations down. These days the main predators are fishing birds of various kinds. Although effective, they are not numerous enough (and probably will never be) to keep the population growth down. They also appear to be less attracted to lakes with low quality fish and tend to move in as the quality increases.

Because of lack of natural predation, the lakes tend to easily get overpopulated if left alone. This is not true of all types of lakes as there are many factors involved. Available spawning ground to the size of the lake being the most important one. During an overpopulation, quality will decrease. The fish will get skinnier, smaller and have a tendency towards getting more parasites.

When having fish as a staple, one does not want to eat low quality fish. The fat content is essential for not getting tired of them and also to get enough energy. Larger sized fish have a higher capacity for storing fat and although very small fish can be good for frying, you will generally want to have larger fish because of this reason.

In order to remedy overpopulation, we are keeping a constant, very high pressure on the good lakes and we try to reduce the fish population to below normal carrying capacity when restoring a lake to good condition. Such a high pressure on the fishing will allow the feed insects and crustations to recover and create better conditions for the fish. This can involve fishing thousands of fish and in large lakes it is an enormous job. The quality will often be so poor it is not worth keeping more than 10% for food during such stages.

You want to fish as much as possible on the smaller sizes of fish in lakes with high reproduction. The larger fish cannibalize the smaller and spawn at a slower rotation (like not every year). This will thus over time help the lake into a higher degree of self-maintainance. Some of the larger fish will however be so stunted that they are beyond recovery. These will gradually be taken out even in nets that are too small for them. But they can persist for a surprisingly long time.

The example below are lakes where Jon (jonsbushcraft) and I have been doing the majority of the fishing. The first years we threw away more than 50% of the fish. Now we are generally throwing away less than 10% and the quality is experiencing a major increase.

The statistics below are from when we started the project. We are not quite done for this year yet, but the majority of the catch has been made. Unfortunately we did not record the weight during the first years. However, we did for 2020, so I am including that to show that the average weight is still pretty small.

Shorting Civilization to Zero

As you may or may not know, I have been mainly focused on learning the craft of trading and technical analysis over the past few years. This comes in addition to me being more self sufficient on wild food than I ever was.

My observations is that we have probably reached a major top, perhaps even THE major top in the stock market. I am inviting you all to a potential bear trade that will make the financial crisis look like a walk in the park.

The cost per month is 50 USD and it is expected that you have at least basic knowledge of trading and risk management.
