Doors: completed

With the outer frame already built I continued with the doors. During the last couple of days I made the frames, aligned the hinges and had them welded. I also started to cut the expanded metal for the body and made a couple of simple handles.
Today while working on the rack closet the welder died on me for no apparent reason. But, after power off it made a couple of noises and the fan ran for a moment.
For being a Chinese machine it actually looks quite good and neat on the inside. The boards have conformal coating and just a tad of flux residue on some pads. The only thing out of place was a blob of solder on a header instead of a jumper.
I made a couple of measurements, the high voltage section was fine but the control supply was totally dead, except for a brief moment when turning off the main switch. Traced back from that board until finding a small block with a forward converter (kinda odd, I expected a flyback). The only component with bad readings was the recovery diode. I swapped in an UF4007 and at the next flick it was alive again.
Of all the things that could go wrong with a welder on novice hands this was not expected.
The next step in the making of the rack closet is the front door frame. It’ll be screwed to the base and the top support. For that I’ll use some square tubing with a cap and nut welded to each end.
The lines scribed on those pieces look a lot like the iconic map of La Plata.
Each one was beveled and welded in the tubes. I ground the sides flat mostly for looks.
As I still had a while more with sunlight I used the support built earlier to keep them in place and tack everything together. Enough work for a Summer Friday.
So, after tearing down part of that wall we needed a safe way to store the equipment. It also has to be a bit above floor level, as we plan on making a small stage.
For the base I used some C channel iron. Parts of it were a bit mangled, so I made a makeshift tool with an hydraulic jack to spread its sides and have a good fit.
The top is simpler, it just needs to hold the vertical struts in place and the light fixture.
Then I centered it on the base and proceeded to punch and drill the holes to locate the rest of the structure:
(Sounds nicer than saying dumpster diving eh?)
We can learn a lot about a society just from looking what we throw away (see Garbology).
When I lived in Berisso it was really odd to see on the curb something that worked or was fixable.
Here in La Plata and without even trying I stumble upon stuff that is just a little bit broken if not working (albeit a tad old).
This last two months among other things I picked up with my bike basket:
This is not exactly dumpster diving but I also helped the widow of a neighbor silent key to clean up his shop.
Out of the deal I got:
It’s 2018 and webcomponents are not ready. We still need to use polyfills, there isn’t a nice way to package everything and let the User change and discover styling.
Sigh.
We decided to tear down part of the wall that divided the old studio from the control room in order to have a bigger space.
Before it looked like this:
And after a bit of effort it became this:
Today I was trying to finish some drafts and sorting out material for the next ones when gossiping around I got the news that Dolores O’Riordan, the lead singer of the Cranberries, passed away earlier this week.
I missed them whey they came to Argentina but they’ll always be special for me, as the first time I kissed a girl (that later became a Real Woman, unlike most of her contemporary gals) we were dancing like dorks to the tune of Ode to My Family.
After making a lot of room on the shed I still had this feeling that the space was under utilized and I started to think of a small raised platform of sorts.
As luck would have it I had some leftovers of C channel from another project and they are perfect to make a frame and put some osb boards.
They are a bit cumbersome to handle by myself so I built a couple of hoists with some sheaves and scraps.
This proved to be extremely useful not only to lift but also to keep everything in place when drilling the wall.
It took a couple of days but I finally managed to make it with a bit of help from my dad.
On the back of my current house there’s a shed where my parents dumped most of the stuff that belonged to my grandparents, even a car.
For quite a while I was in need of a personal space to work and store some tools. So earlier in December I started to move things around, give away some stuff and trash the rest.
It’s a pity I didn’t take pictures of the initial state but before this I could only peek from the door.
Looks messy but this is an incredible progress:
Since I moved back to my childhood neighborhood I reconnected with a lot of people that were part of my developing years and imprinted many memories that I still recall fondly to this day.
One of them is a very nice old man, a bit younger than what my grandfather would be were he be still alive. From time to time I help him with the daily errands and every other week we share a simple lunch. He used to run a hardware store that marveled me every time I went (when I was a child I could be impressed with simple things. Thankfully, now I still do).
Nowadays the store is run by his sons. He comes anyways, sits on a corner drinking mate and welcomes the patrons. Besides knowing almost everyone around he’s also versed in almost any trade I can think of and that skill is quite useful, as many times people come without knowing what they need or how to fix something.
I visited him for new year’s eve and between a glass of wine he said come to the shop once the holiday craze fades, I have something for you.
A couple of days later I go to the store and without a word he carries me to the back into a room I never visited before.
This are all the returned items that we can not send for repair. Some customers are worth keeping and so we just give them a new machine instead of washing our hands because the manufacturer would not take them. Pick what you want, we’ll talk business later .
I got this out of the deal at a very discounted price:
Besides that he sold me safety gear, consumables and a couple of other things like magnetic squares and pressure clamps, air hoses with quick disconnects, a paint gun and a spraying one.
You don’t look at a gifted horse in the mouth but given that these were rejects I had to.
The welder was only banged a couple of times on one side and had some loose connectors. After fixing that it worked flawlessly. It came with all the torches, water tramp and pressure regulator and spares.
The compressor is way loud and one of the connections between the reservoir tanks and the regulator has a leak, I can see oil (or moisture?) bubbling when it’s running. It’s not a big deal and while the fix is easy it involves fumbling with very delicate tubing and I know from experience that a bit too much of torque can easily wreck them. Also it’s not very ergonomic, the handle has sharp edges and if I’m supposed to use it to move it around I have to crouch. As it is not very heavy I just lift it whenever I need to move.
The drill had less than the barely minimum grease on the table lift column (none) but surprisingly the chuck turned smoothly after loosening the belts. However the quill felt strange, like it was scratching something inside, and also the spring was harder than I’d like to. To dismantle it only needed a single screw to be removed and when it was out I swept the innards with a cloth and it came back with what looked like metal (or very thick paint) flakes. After making sure that none of that remained I applied a very generous amount of grease and put it back together.
Runs quite fine but the table has a bit of flex, nothing that a brace wouldn’t fix.
I don’t know what’s wrong with the miter saw. The stock abrasive disk is very soft and flexes, so making square cuts is a difficult task, and it really needs to be bolted on something hard, otherwise the frame tends to distort when applying pressure to the vise (just the necessary to keep things in place, seems like a production defect).
All of this came just in time, as I’m doing a couple of renovations on my parent’s house. (The neighbors are not exactly thrilled, as all of these tools make quite a bit of noise).
Sunday was a very nice day among friends and partners of our neighborhood.
Instead of finishing a draft post about that I’m sad. I spent most of this Monday listening to our representatives going around circles instead of voting, while some of my friends were treated like terrorists, being searched by masked officers at gun point, others punched and kicked.
I listened to the live stream for about ten hours before the sleep took over. Most of the ‘normal’ people I met yesterday chose to ignore this and watch crap tv. Meanwhile in Japan they have entertainment shows like Supreme Skills where they pit engineers and craftsmen to see which one is able to complete very demanding projects. Some of them are very light on the details but nonetheless the content is still better than other productions and showcases a complete different scale of values.
On weekends most of us choose to numb our minds with meaningless stuff. Others enlighten themselves.
No wonder things go downhill.
So, it turns out that my biking escapades to Los Talas or walks among the forest have a greater side effect than letting me vent and clear the mind while it works on the background.
Urban environments tend to capture attention dramatically and require additional directed attention. Natural environments are as rich, if not richer, but tend to invoke involuntary attention more modestly, allowing directed attention mechanisms a chance to rest and recoup. Interaction with nature improves your ability to perform directed-attention tasks—things you need to concentrate on.
So says researchers from the University of Michigan in Cognitive Benefits of Nature Interaction (Psychological Science, December 2008). They’re looking at a side-effect free, zero-cost, readily available therapy to improve your cognitive functioning. All it takes is a walk in the park.
