Flies are often unhygienic, pestilence spreading, and in many ways annoying buggers. But I do admit that I like how they look.

I did not feel like working on knives today, so I have decided to make the measuring pin from brass. It took me rather longer than I expected because I had to work out several things on the fly and there were therefore several failed attempts and repairs. But I managed it in the end and the result looks kinda cool. And it works just as well as the wooden one, in addition to being ever so slightly more precise.

The bent brass pin on the right is screwed and glued into the lower half of the pin and goes through a hole in the upper half where it has slight (several tenths of a mm) clearance.

Here you can see the upper jaw, where a ground wood-screw holds the spring tightly in place. In combination with the bent brass pin, this holds both jaws fixed against each other so the tips do not misalign (too much) when used.

On the underside is no screw. Originally I thought that two bent brass pins in the back portion will do the trick. But it did not work at all, it turns out that make something like that precise enough by hand is impossible (for me at least). When you look closely at the pictures, you will see that there are plugged holes where that second pin was. If I were making another one, I would try to ditch the guiding pin altogether and fix both jaws to the spring with a screw. Whether it would work better or not I do not know, since I stopped tinkering as soon as I got a working product.
And the second tool that I have made today is a center scribe.

It is a piece of black locust wood onto which are fixed two small ball bearings. The axes are just press-fitted both into the wood and into the ball bearings. Black locust is strong enough to hold and if it splits, I will make the body from aluminium, this was just a proof of concept.

Here you can see the other side. The wood-screw goes all the way through and just the tip pokes out between the ball bearings. Should it turn out necessary, I will eventually replace the screw with a re-ground drill bit, but for testing, a screw was a readily accessible and easily applicable piece of hardened steel.

To scribe the center on a flat bar (in the future on an outlined blade) it is simply inserted between the ball bearings so it rests firmly on both of them and on the screw tip. When dragged through (for example downwards on the photo, assuming the tip of the tang is down), the screw tip inscribes a line that is very close to the center. Not perfectly, but I can also scribe a second line by dragging the piece of steel through the assembly in the other direction (putting the tang up in the photo and dragging that way). These two lines very close to each other are sufficient enough for me to grind the blades symmetrically, after all, it is better than what I have used so far.
When grinding blades, it is important to have the ridges, fullers, and similar as symmetrical as possible, especially before quench. An asymmetrical blade has a much higher probability of warping or bending in the quench.
On an unhardened blade, one can scribe markings with a scribing needle and/or compass, but once the blade is hardened, that is no longer possible. And I still want my blades to be at least mostly, even though not perfectly, symmetrical too.
I used to measure the symmetry with a help of a folded piece of paper that I have cut with shears so that it has two perfectly aligned points. When folded over the blade, I could easily-ish check if the points align on the ridge on both sides and thus check where I shall grind more during the polishing to keep the symmetry.
But the pieces of paper get wet and manky in the process, and I kept of course losing them so I had to make new ones over and over every day and sometimes several times a day. And today I finally got an idea how to replace them with something much better and hopefully permanent. I took one wooden clothespin and I ground it in about 5 minutes to sort of mini-calipers that can be clipped onto a blade

This pin is made from softwood so I could not make the point too refined, but I do not need to. I want to make my blades mostly symmetrical, not perfectly symmetrical. And anyhoo, I shall, in the future, probably make a better and more precise one out of brass, this is just a proof of concept.
And it works well, here you can see it in use. It shows that the ridges on both sides are within few tenths of a mm apart, and that is good enuff for me, that is a difference that cannot be seen with the naked eye and is not easy to measure even with calipers.

Earwigs are not normally associated with flowers, but they can occasionally hide in the flower buds if they provide enough dark end enclosed space to hide in. This one did not manage to completely hide because this bud is healthy and still well enclosed with leaves. Some other flower buds were badly damaged by slugs – hollowed out in the middle – and those were positively filled with earwigs to the brim.
I do not know why many people fear earwigs, they are completely harmless and very shy animals. When disturbed, their only worry is to scamper off somewhere secluded and dark as soon as possible. They do not climb into ears to eat our brains, but they do eat mites and aphids, so they are an asset in the garden.

Today was a blade quenching day because according to the weather forecast, it might have been the only sunny day in a while. Luckily, I have managed to finish a batch of 8 blades to a sufficient state for hardening so I set out to do it first thing in the morning. And when I was taking fireclay bricks – not for fireplace, just to hold the quenching oil receptacle upright and steady – this fellow was hiding from yesterdays deluge in a crack. It got lucky I did not squish it flat when taking the bricks.
When I put it in the sun, it has spread its wings, soaked in some warmth, and buggered off pronto so I only managed to snap one picture with my phone. But it came out quite well, I think.

It is small tortoiseshell Aglais urticae. These beauties justify the existence of stinging nettles.
There is plenty of grasshoppers around, and technically they are a pest. However, unlike slugs, I have never noticed them do any noticeable damage on crops, local species seem to prefer grass over anything else.
This individual is the only one that I have seen sitting – just sitting, not munching – on one of the sunflower plants. And it stayed long enough in one place to get shots from different angles.

I was not trying to photograph this one. I did not even see it – I was aiming for a grasshopper. But the camera autofocused on this tiny spider who seems to have caught an even tinier insect.

There was a beautiful, big facehugger, bright yellow like a bead. But it was raining and the next day I could not find it. I only found this tiny one, hiding behind one of the petals.

I have planted several sunflowers this year. Slugs did a number on them, but they did manage to blossom at least somewhat. And there are some pretty critters showing along so there will be a series of pictures in the next few days.
Today this beautiful female great green bush cricket. I was afraid of these when I was a wee little kid.

I was born on Friday 13th, 45 years ago. This Friday, to be precise. When I learned that it is supposed to be a “bad luck” day, I thought to myself “that makes sense, considering…”.
I am not superstitious, but whenever I reflect on my life so far, I do think the same still, although in some respects I am among the lucky ones. But depression does not lend itself to dispassionate analysis.
Anyhoo, this year the world burns, again, and it keeps getting worse. Hooray.
If I were on Twitter (which I am not) and if I were keeping up with what flavor of nonsense TERFs are currently peddling (which I am not) I would probably notice that they are trying to claim late Terry Pratchett as a transphobe.
And if I were making YouTube videos (which I am not) I would make one just like Shaun did (and I did not).
Whenever I think about trans issues and Terry Pratchett, the Monstrous Regiment immediately springs to mind. I did not like that book after the first reading, which was rare for Discworld books – I liked most of them straightaway. But it grew on me with subsequent reading and like most Discworld books I ended up reading it multiple times and I probably will read it some more before I finally die.
We cannot know what a dead person would say about some issue. Even a word from their living friends and relatives might not be entirely reliable, since friends and family could tend to be overly favorable when judging their loved ones who passed on (although when multiple people say the same, it does bear significant weight). Throughout the books, many things about Pratchett become apparent, among them his deep humanism and knowledge of the intricacies and complications of the human condition. There is absolutely no doubt that he would reject any notion of trying to shoehorn people into neat little boxes with simple definitions. All of his books stay and fall on the only “simple” fact about humans – that each is their own person and categories and words are mere imperfect crutches that we use for communication, always imperfectly.
Yesterday evening when watering my citruses in the greenhouse, I heard the typical cry from a nearby oak tree and when I looked there, I saw these two cuties sitting atop of it. They were kind enough to wait for me to go inside and fetch the camera, but not long enough for me to get the exposition settings right for the crappy lighting – I only got one shot and they whooshed.

In case you are wondering, the tree is living, but it was struck by a lightning a few years ago and it has one dead branch on the very top and a strip of deadwood down to the earth since then. Right next to it is an ash tree with a dead branch on which I have photographed kites a few times.
Raptors like to sit on dead branches, I guess they provide them with a good view.
The title says what this will be about and in my opinion, it is not much different from what one normally sees when making soup. However, some people might find the pictures disgusting so be warned. [Read more…]
