Making a Rondel Dagger – Part 16 – Chape

I had a very busy Sunday. My vacation is nearing its end and I have been hell-bent on finishing this project already, but things got in the way all the time.

The biggest problem with the chape was that I could not find any information about how to do it properly. There are some pictures of finished products  and some info about casting them from bronze, silver etc. but not about how to form one out of steel. So I had to start from scratch.

My first two attempts were completely unsuccessful. I do not even have anything to show you  – you are free to imagine some vaguely rectangular and bent piece of metal. What I am going to show you is my third – and final – attempt. I do not call it a success either, but it is at least big enough part of a success to yield a usable product. But I am not satisfied with it and I had to repress the urge to hurl it out of the window with great force.

In retrospect I think my biggest mistake overall was using too thick steel. The shovel that I was recycling was ca 1,5 mm thick and for this purpose probably half that thickness would be appropriate. Unfortunately I did not find any suitable piece of steel in my scrap pile.

Should anyone wish to avoid some of the mistakes I have made, here is the most important thing I learned: do not try to do it without dies and templates. It is a complete waste of time. Chape is a very complex piece of metal, bent and formed in multiple directions at once.

I wanted only the front face to be pretty, but even that has proved to be beyond being doable without a template, definitively without  a skill that I lack. And since I  also lack screw press, I had to do with my vice. So I have built a set of jaws – one formed approximately as the tip of the scabbard, and one with a matching hole about 2 mm bigger on all sides. After this I have heated a piece of steel, put it between the jaws and pressed it as quick as possible. After a few repeating and some repairs/adjustment of the jaws I have finally got a  shape that at leat partly fitted the tip of the scabbard. I might be on the right track here.

However, after a few presses the metal had nowhere to move – so I have cut it into stripes that I have intended to bend around the scabbard. I have again made the mistake of trying it first without a template. Again, complete waste of time.  I have only managed to bend them so they point straight to the back of the chape. I could not achieve the second bend to close the flaps around the backside.

So I had to fish around in my scrap pile some more. Two cuts that were left over from making the jaws have proved to be useful here – when put back to back, they were the same thickness as the wooden scabbard, therefore I reasoned I could make a template out of them.

So I took an angle grinder to them and made two nearly identical halves that mimicked the wooden scabbard. A few touches with a file were also needed in order to round the edges etc. I am not going to toss these, I am going to keep them as well as the jaws in case I need to do similarly shaped chape again.

I have deliberately made this template so most hammer blows will be perpendicular to the vice jaws. No matter how strongly you close the vice jaws on anything, hammering or filing/sawing it will eventually loosen it or break it. That is actually a reason why specially formed jaws with a groove have to be used for holding round stock.

With this I was finally able to bend and hammer the steel flaps all around so the fit more or less snugly around the tip of the scabbard. I did not want to close it all the way around and I intended to leave the stitching visible, because it was more or less clear that I will have to hammer and ever so slightly bend the finished chape onto the tip so it holds and does not fall of. However, I wanted to at least braze the gaps on the sides. I failed to do that, because I run out of silver solder and I will be damned if I spend another 10 € on this. At this point, I was starting to hate the thing. So I brazed as much as I could and sod the rest. Here you can see it all black, covered in solder and slag and scale. I have again carefully ground the excess solder with fine file and collected the silver dust, but I still did not feel like experimenting with making solder out of that dust.

This is when It I have got the only idea during this whole process that I consider valuable – I have found out that old, nearly worn angle grinder wheels are excellent for scraping of the scale and the slag – both of those are harder than files and they tend to smear abrasive papers. So a bit of water now and then to wash of the dust and a bit of scrubbing with an old wheel and I could proceed to polishing without covering my belts with grime. Polishing I have performed the same way I did with the throat. During this I have found out that the chape is much more asymmetrical than I was hoping for and that there are two poorly brazed spots on the sides. leaving unseemly spots, but as I said, sod it, I am not going to do this thing again.

When the chape was finished, I have put it and the throat on the scabbard and gave both parts a few wallops with a wooden mallet on a wooden board so they hold in place (for the throat I had to put a piece of leather on one side between the backside of the scabbard and the throat for better fit). And then I walloped it all some more so it holds.

So now the project is almost finished. All that is left to do is to sharpen and sign the blade, tie a leather strap around the scabbard and treat it with dubbin and make pictures. Neither of those things should pose any big problems and except the signing they cannot destroy anything. I hope.

Despite being a non-believer, I do understand the desire to be able to pray – a desire to have some control.

Slavic Saturday

I do not think I could make this a regular feature, but possibly an irregular one – some random snippets from the Slavophone world whenever I notice something interesting – be it art, traditions, languages, politics. Let me know if you would be interested.

I instantly fell in love this song (and some others from this band). It is so cheery and silly. And I love violin.

And yes, the text is silly, although my Russian is not so good so I could understand it all instantly. But I was able to parse some and with help of online translators translate the first half for you. Unfortunately I cannot translate all, because translating it into English was not only much more time consuming than I expected it to be  – but above all I started hiting on phrases that are probably Russian idioms whose meaning I do not know. Being able to understand the gist of something and translating it into another language is not the same thing I am afraid.

I ain’t no poet in addition to my rusty Russian, so take the translation with a grain of salt. The Skobari (скобари) is an ethnic group in Russia and I could not find any proper anglicized word for them. And you probably won’t be able to sing along the translation with the original.

Who goes there, who goes there
have a look at who goes there
riding on a crippled mare
that sems to be our Skobari.

Skobari are a jolly nation
going home from a fare
one bare naked, one bare footed
and one with an injured head.

Play me such one
Skobar funny
so my tummy doesn’t hurt
tummy mine, the sinner’s one.

Play me such one
thats good for dancing
but not for every
snot nose prancing.

Smashhing up, smashing up
I feel like smashing up.
And truth be told you
I feel like brawling too.

Who’s that lad
prancing knees
hasn’t got hands on
aspen sticks.

Pennies for a party one
daddy collects his loot.
Mom whispers in his ear:
“Don’t you get drunk you silly fool!”

I was born hopeless
with no respect too –
should the heads roll
I’ll tie the rope.

I am breaking, back is arching,
I’m not really feeling well,
give ne just one half a litre
and I no doctor is needed.

We saw the grave of the one
who called us drunkards.
We did drink for our own money
nobody was serving us.

Pollination Party – Moths 1

More perfect shots from Nightjar, this time Hummingbird Hawk Moth Macroglossum stellatarum.

It reminded me of a fun anecdote – during my studies at uni, one of my half-classmates mentioned one evening in the pub that he has observed a beautiful hummingbird in his garden. Pedantic killjoy as I am, I have pointed out that there are no hummingbirds in Europe, so what he has in fact observed was in this moth.

It was mildly embarrassing moment, because he was his half-classmateship was the biology half (me studying Biology-Chemistry, him studying Biology-IT). But there was no real reason for him to be embarassed. Nobody has perfect knowledge about everything and their similarity to hummingbirds in flight is really uncanny.

I have seen these beautiful moths occasionaly in my garden, but never when I had camera in hand.

 

 

Itsy, Bitsy, Dance

There will be more spiders from you! In the meantime, I think this green spider looked lovely when it waved at me from our plum. The way it was running around on that leaf it looked like some sort of dance routine.

Shake it to the left…

Oh, didn’t see ya there. Hi!

Anatomy Atlas Part 20 – Lungs

Our amazing breathing sacs, evolved from an invagination of our gut. Had that invagination been dorsal rather than ventral, we might be spared that awkward crossing of tubes that makes eating and breathing at the same time so dangerous task.

Id did not go too much into detail here, but I did outline the branching of bronchi and bronchial tubes somewhat. Which is an interesting issue in and of itself.

The tubes do not simply split willy-nilly, the branching is really intricate and is optimised so that at every fork the air pressure stays the same, thus guaranteeing that all tubes contribute to the air exchange and there are no (ideally) pockets of stationary air. This is no easy task for engineering, piping is difficult to make and ventilation systems in buildings often need additional ventilators added to the pipes at various places to compensate for pressure drop at some junctions.

In our lungs this is partly achieved by the fact that there are no right angles anywhere and partly by the fact that the forks are arranged in such a way as to reach all the alveoli with the shortest possible amount of piping. In modern engineering such tasks beyond certain level are allegedly sbest solved by evolutionary algorithms, because there are too many variables involved for simply designing them right of the bat.

Itsy Bitsy and Very Lively

I dug out more spider pics, because, why not?

I have made these pictures last year, but I never got round to send them. These were one of the first macro shots I have made, when I still did not know what I am supposed to do (I still do not, but slightly less so).

This spider is slightly translucent and very small – that mesh is just a few mm across, it is the texturing on a sheet of extruded polystyrene that I have used to make thermally isolating covers for my sewage treatment facility.

I love the copper colour of the abdomen contrasting with the translucent green of the thorax and the legs. It looks like made from glass or gemstones and precious metal. Actually it could be a nice inspiration for a jewelery, if it were not a spider. But maybe there is a market for spider shaped jewelry?

I just could not get a good shot at its face. It was running around constantly and in all possible directions, not staying still for a moment. But I noticed that under certain angles its eyes seem to reflect light like cat’s and I managed to catch that on a few shots. Then I have let it scuttle away, taking care to put it in a place where I will not squish it.

Behind the Iron Curtain part 15 – Cars

These are my recollections of a life behind the iron curtain. I do not aim to give perfect and objective evaluation of anything, but to share my personal experiences and memories. It will explain why I just cannot get misty eyed over some ideas on the political left and why I loathe many ideas on the right.

Cars were some of those goods that were difficult to obtain and difficult to maintain, even when you had the money – so we never had one. We did not exactly need one either, because public transport was in those times sufficient. It was not market driven and thus was not dependent on population density.

However cars were still useful and partly they became a status symbol so many people in our little town never understood why my parents did not get one. One of my mother’s colleagues was visiting us one day and she snooped around in our garden shed looking for the car she was convinced we have stashed and hidden away there. She just did not understand that my parents did not use their positions to enrich themselves and get the much coveted goods of the time.

What was fairly typical of the cars was their distribution in any given land. Someone interested in cars could probably travel in hibernation between the various lands of the eastern bloc and then recognize which country they arrived at by looking out of the window at the nearest parking lot.

In Czechoslovak Socialist Republic the far most predominant cars were Skodas, at the time of my life mainly Skoda 120 and towards the end of the regime occasional Skoda Favorit. There were zero cars from the western part of Europe and a very limited amount of cars from other countries in the Soviet power sphere. Father of one of my classmates had a very coveted Lada VAZ-2101 “Žiguli” which was admired for its sturdiness and strength as well as for being essentially very rare piece. He only could afford it – and get his hands on it – because he was middle ranking military officer of the border patrol.

The parking spaces in CZ were mostly empty and usually there was some mix of different cars despite the prevalence of Skodas. I was not used to seeing many cars all at once, or a parking space really full.

So when I was visiting East Germany for a summer camp at about eleven or twelve years age, I had an entirely new experience at that time, one that was very strong to an impressionable little child.

Rows and rows of cars stretching for hundreds of meters on each side of the street. Parking lots so cramped it was difficult to squeeze between the cars. Different colors, but all the cars were essentially identical, leading to strange uniformity. All were Trabants.

Trabants were known in CZ, and they were much derided. They were the cheapo cars for those who could not afford a “proper” car. Having a Trabant was seen as a sign of under achievement, barely better than having no car at all. There were – and still are – many derogative terms for the car, like “angry vacuum cleaner”, or “bakeliťák”.

This added a discordant note to the experience. Seeing that eastern Germans had apparently more cars than we gave me a sense of awe, seeing that the cars are of lower quality gave me a sense of superiority. However the strongest of all the memories is the sense of a complete lack of choice and of a mind-numbing uniformity wherever you go. It was my first experience of an outward demonstration of the fact that we are actually expected to blend into crowds. And that everything in the system – all the overt legal and covert economic pressures – is designed to quash individuality and make us into a uniform mass.

I did not form this opinion so clearly at that time of course, but this was the start of that realization.
