Oh Deer!

This is not a common sight. A single male roe deer, grazing near-ish our house in the middle of the day. He seemed quite unperturbed by a few cars passing the road about 100 m from him. And he was so focused on munching grass that he barely ever raised his head above his shoulders, so I mostly got pictures of his ass.

Sunflower Residence – Bumblebeeeezzz

I do not know the species here and I dare not to identify it. But I do not remember seeing bumblebees with this color regularly here, whereas this year they are almost the only ones I see.

Argiope bruennichi (Wasp Spider) – Belly

This is very probably the same individual, it is not like these spiders are very common here. This time she has build a web near the front door to our house and she was there for two days. She has caught one caterpillar but nothing else, so after two days she packed up her ropes and went somewhere else. But on the second day, she was on the web with her back towards the wall and her belly towards me, so I could take a picture. See below the fold.

I had the species identification confirmed by an actual spider scientist.

Sunflower Residence – Some Green Fly

This one is very green and very hairy. I do love the metallic sheen. It would be lovely if that kind of color could be replicated on a real metal surface, especially if that surface were steel. But it can’t.

Midsummer Afternoon – Part 1 – Visit to Harakka Island

Guest posts by Ice Swimmer

It was a hot afternoon just after Midsummer. I went to downtown Helsinki to take some photos.

In the first photo, you can see a jackdaw walking at the Market Square tram stop. I took the picture while waiting for the tram.

The second photo is an “aerial photo” of a family of mute swans, two adults,

and five little cygnets. I’m on the shore end of the pier, from which the boat to Harakka picks up passengers.

I think the leftmost cygnet has some Cladophora around the base of the neck, at least I’m hoping it’s that and not plastic (I noticed the green stuff when looking at the edited photo). The green algae, which has a Finnish name ahdinparta, beard (parta) of the old Finnish god of the sea Ahti, is rather ubiquitous in shallow waters here and there’s a lot of it on the underwater stones in the picture.

I took the boat to Harakka. The digitalis was in bloom and there were wild strawberries. It could be that when the Imperial Russian army was using the island before Finnish independence, they planted strawberries and other berries, as I’ve heard stories that it was their way to prevent the soldiers in fortress islands from having scurvy.

This red-leaved rose was growing in a forested area on Harakka. I like how simple and unpretentious it looks.

Most of Harakka is ruled by dinosaurs in the summer. This gull seemed to be above any ergonomic considerations.

My visit to Harakka was cut a bit short by the low battery charge level of my phone. I had neglected to take an emergency charger (“sähköpossu”/”electricity piggybank” as I like to call them) with me.

Having come back to the mainland from Harakka, I saw these crows on a sign (warning about the underwater cable AFAIR) on the pier. They were “singing”. There’s a Finnish saying “Äänellään se variskin laulaa.”, which could be translated as: “Even the crow will sing with its own voice.”

I did take more than these pictures on Harakka and there could be material for further posts.

I haven’t watched any other of her videos yet, and I must say that I do not like her choice of accompanying music very much*, but her handiwork is beautiful.

I do in fact enjoy woodturning videos most when they only have the sound of the lathe and the chisel crunching the wood. I do not know why.

Bumblebee Ride

Avalus had a little run-in with a bumblebee and was so kind to take pictures.

I was walking from the bus stop to work and saw this bumblebee, just sitting on a vetch leaf. I got my cam out and began photographing. The bee was stumbling around and looked kinda lost.

And then she leaped at the camera and started crawling on my hand, eagerly searching. (These pics were taken with my phone).

She was not extending and waving with a middle leg, which is usually a sign for „please mind your distance, thank you or I’ll sting you“, so I carefully juggled her onto my left hand and took her to the nearest batch of flowers. These were of some crownvetch (Securigera varia) and regular bees were bustling around. My passenger-bee was at first not interested, only noticing the flowers as I moved her head directly in front of it.

She then tried drinking nectar but she was too clumsy and just pierced through the flower with her tongue. Irritated, she crawled a bit over the flower, but always kept a leg on my finger.

You can see the tip of her tongue, sticking out of the back of the flower.

Then she lost interest, crawled back, and just sat at my hand.

My original plan then was to take her to my office and get her a drop or two of freshly made sugar water to nurse her to strength and then put her back in the field I found her in. But underway I found a thistle with many freshly opened flowers that were at ground level (It looked like the plant was crushed by a car in the past but went on to grow anyway, but the flowers were all within 2 cm of the ground). This looked like a suitable spot for my shaky passenger, so I offered her a place in a thistle flower which she took up immediately, thrusting her tongue deep in. I stayed for a few minutes and observed her, as she drank, she stopped the shaking so I think she got all right.

So good luck, big bumblebee!

I like bumblebees, they are co-cute.

Tiny Spider Eating Tiny Prey

This tiny little jumping spider was munching on a fly on my house’s wall, nearly in the same spot where I took a picture of a wasp spider a few days ago. Unfortunately, these little buggers are at the very limit of what I can photograph free hand and I did not dare to go for a tripod/monopod because it would probably bugger off.

Pictures below the fold. [Read more…]

Argiope bruennichi (Wasp Spider)

This species is not native where I live, it migrated all the way here from the Mediterranean late in the 20th century. I have never expected to see it in my garden since it still requires a generally warmer climate than what used to be normal here. I guess we can chalk that up to global warming – and this year’s summer was uncharacteristically humid and cold, almost like it used to be when I was a kid.

Pictures below the fold, beware of an intimidating and beautiful spider. This specimen is not particularly big – the abdomen is just about 7-8 mm in length. Maybe she is not fully grown yet. [Read more…]

Sunflower Residence – More Flies

I have no clue what species of fly this is, but it looks sleek and dynamic.

Sunflower Residence – Various Flies

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

T’was Tool Making Day

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.

Caliper Pin – New Knifemaking Tool

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.
