Exotic Scrapyard Finds! Repair-A-Thon!

One of these observations that I have made in my own life is that we as humans often strive for security and that our thoughts and actions are often governed by fear and it is difficult to say if a point will ever be reached. in life where we will be free of that if you struggle to make ends meet and work very hard to build something for yourself, you will probably do so with the feeling that all you need to be happy is to earn a little more, even if it's just the most basic things. in your life were covered how wonderful life would be at that moment your fear revolves around being able to pay the next bill, it's all about survival, well skip ahead a few years and you might make more money than you need to survive, but now all of a sudden, you may realize that a new fear has entered your life.

What happens if I lose what I just built? The situation has definitely improved, but you see that feeling of fear. I'll probably never give it up. You simply readjust your focus. It may be the health of relationships. problems, whatever, in other words, yes, it is wise to strive for security and work towards it, but the big questions will probably never stop haunting you and that is why, in my opinion, it is a good idea to fill in the gaps of remaining time answering questions. In fact, you can solve problems that may be difficult, but not impossible, to answer and, IMHO,

repair

ing and reusing things is simply focusing on a very specific goal, bringing something back, creating meaning where others see the end of it. a story and if you If you are like me, you will find joy in that, in that sense, let us see what we can find today in the junk here, this huge blower here is nothing I really need for me, but I know someone who does , so we'll try to do it.

Get it working again. This side channel pump here is probably 50 years old, but since the floods we had last year in Germany I can't walk past any quality pumps, so I'll buy that too right now, not sure. What is this strange looking device, but it oozes quality and I'm curious to take it apart and see what it does. I was actually about to retrieve some of the pieces of this contraption here, but I was too slow and it broke. into pieces before I could get there, although I found these two workshop cards here and we'll work on them a little today and since I found some interesting stuff there for the last episode, I also visited the thrift store again and got lucky again.

I found this rare digital audio recorder and an absolute treasure, a brown audio 300 stereo system from the late 1960s and I would say let's do the best we can to bring those treasures back to life, let's start with something fun then and although This It is also very heavy and is not without dangers. It would certainly be exciting to see this huge blower in action. It is a three kilowatt centrifugal fan made by the German company Seal Arabe, apparently around 2007 and compared to most of the articles in this series. It is practically new however 15 years was more than enough time to accumulate a centimeter thick layer of dust and dirt on basically all internal surfaces and what you see on this dustpan is simply what fell off the casing of this fan just by moving it around the workbench and that's why I'm now going to start taking this device apart which means I want to take out the impeller which also contains the motor and that's why I started removing this cable from the cabinet at the back of the cover of In this terminal box here we also find a wiring diagram and it tells me that this is a three-phase induction motor that can be connected in delta or y configuration.

I spray some penetrating oil on the bolts that hold this three-branch part that holds the engine. great spot i also marked the parts so i can then reinstall everything exactly the way it was originally oriented after turning the housing/boot on its side and having removed the parts holding the impeller inside, now i can pull it out. By the way, outside the casing this part weighs almost 45 kilograms, now we can see all the dirt that has accumulated here, both on the hub and rotor blades and inside the volute, as thick as dust. You can mostly scrape it off by hand and then vacuum it up with a vacuum cleaner.

By the way, this friendly looking guy is called Henry and we actually found him on the street, on a pile of garbage, three years ago and he turned out to be a real good vacuum cleaner and I proceed by cleaning all the surfaces I can reach this way in the meantime I went out and I'm also wearing a dust mask because I have no idea where this fan was used and what chemical compounds that dust might or might not contain the actual impeller and it consists of curved blades on the outside of this rotor while the hub on the middle contains the motor. a three-phase induction motor to be more precise in German, a hub motor like this is sometimes called ausan leufer i.e. motor with external rotor, the physics is basically the same as in an ordinary inun lever type induction motor or internal rotor, only here the rotor rotates outside the stator instead of the other way around, but a vacuum cleaner only gets us so far in this case. and I guess it's time to reveal my new wonder weapon, also known as a steam cleaner, which I recently bought to make my life a little easier and I don't know if it's based on the nature of the cleaning process or just because it's new. me, but I really like using this thing, it dissolves the seemingly unbreakable bond between the elements of your desire and the dirty, disgusting filth in a matter of seconds, how can something that no one put any work or effort into and that turns out to be as strong and persistent as the power of which dirt sticks to everything and I am trying to clean all the blades preferably when they are under the hub so that the condensed water does not somehow seep into the engine because that is, of course, a of the things you have to be careful with. about steam cleaning, it also works wonders to remove old stickers that usually surpass even dirt in their adhesion and I also clean the inside of the balut and after that the pieces are dried quickly with an electric heater, now it would be possible to Separate the roller but frankly I would only do it if I could hear or feel the bearings being worn or if there was damage to the cables which doesn't seem to be the case here and here is a little before and after comparison.

After the whole cleaning process and getting back on the workbench, I was able to put the blower back together. The reason I brought this device home is that very good friends of mine just moved to a new shop and recently told me. which you should keep an eye out for something like this, they need a big fan or blower to circulate the air inside your new building so let's see if it works, it probably doesn't seem too safe to stand next to this beast and that's why here I just tried it During short bursts, the airflow here is so strong that I can barely hold the old jacket in my hands.

Let's take a look at the service cards. This one with its blue paint and overall design style is quite typical of a German Workshop Card. This smaller one also has a very sturdy build, but I'm not sure it's been used in a workshop before. It could have been in a kitchen or somewhere else. What I had in mind here was to change the overall look of these cards. that could be turned into something that would be nice enough to come into someone's apartment or house. You know, I've generally noticed that, at least here in town, more and more people like the idea of ​​using older shop furniture. their houses with the largest card, I started by moving the surfaces with wire, not necessarily to remove all the old paint, but just to prepare it for a new coat of paint, then a degreaser was used and then the surfaces were cleaned before applying a layer.

A lot of hemorrhoid paint was applied, but as you can see in this video here, when coiling the wires, the paint always leaves a mess and it's certainly not good to release the paint dust into the environment. So I tried something else with the smaller card and applied a few drops. of dishwashing liquid on the smaller card and used the steam cleaner to clean the surfaces as much as possible after that, I also treated it additionally with some degreaser and the same hemorrhoid pain was applied as a nice contrast to the dark gray paint. I decided that I would use some flat fir boards that I would just use a clear protective varnish on these boards have tongue and groove connections because they are actually intended as a floor covering material.

I bought them two years ago but never used them for their intended purpose after the paint was removed. It dried for a few days. I inserted the boards and fixed them with small screws from the bottom. We'll have to see if the paint holds up as well on the small card as it does on the larger one, but so far it looks good. and here's a little before and after comparison, you may also remember that a few weeks ago I found this rather tall cabinet here and by tall I mean tall, it's over two meters and 40 centimeters tall and it actually looks comically large when you stand up in front of him.

I'm sure it was once used for an electrical installation, but I thought it would also make a pretty good piece of furniture, so a few more spruce boards were cut so they could simply be inserted here, the cabinet should certainly be attached. to the wall, although I don't know if that's your style, but if I had an apartment or a bigger house, I would gladly put these things there, what do you think? Let's take a look at the pump, so it's another side channel pump and I say that because we had a pump made by the same company, Siemens and Hinch, abbreviated c here in episode 26.

However, this pump is even older and you can see that it consists of two main parts, a three-phase induction motor in one. hand and then a separate pump casing, on the other hand the pump is completely seized and cannot be turned by hand at all after cleaning these parts a little from the outside and removing the protection. First I unscrew the motor from the common cast iron. base to see if it works as you can see here it is attached to the pump shaft with a piece of rubber that will act as a shock absorber between them in this old motor terminal box we still found remains of the previous wiring I installed a new power cable and then I test the motor to see if it works properly, it runs smoothly and doesn't seem to have any problems, the pump on the other hand is completely stuck before I try to disassemble the whole pump, I had a faint I hope it was a little rusty inside and that I could loosen the impellers by pouring some citric acid into the pump housing and well, a reaction started immediately and well, I was able to remove some of the rust, but of course the pump was still stuck so I decided to take the impeller apart. bomb and I knew this wouldn't be easy.

I removed the four bowls that normally hold the entire bomb together and then began removing layer by layer. The last pump we found had a casing that was made entirely of brass apparently in this case the casing is made of cast iron which of course is prone to some degree of corrosion when it comes into contact with water. The rotors, although they look brown and rusty here, are actually made of brass. The axle is made of stainless steel, although it looked very bad at first, I was able to get the rotors to shine a little again and managed to remove almost all the rust from the cast iron parts by turning them with wire; in fact, they had rusted to such an extent.

Since the brass rotors were stuck due to a layer of rust between them and the pump casing, it would have been possible to grind or even machine the cast iron surfaces to get a really smooth finish, but I suppose that would have only made them more prone. To prevent further rust, I instead just rolled them with wire and then decided to treat them with a little food grade grease in an attempt to slow the rust, at least in the near future. The outer edges of the cast iron pieces were degreased and then dried and then applied. a special type of silicone to act as a liquid sealant between all the layers the same also happened with the pump housing flanges I waited for the sealant to dry and that took several days because it was very cold here then I filled the pump housing pump with water, as long as that is the case the pump should be able to prime itself meaning it should be able to suck water from a reservoir even when the hoses are not yet completely filled with liquid and that is actually one of the theorists. advantages of these side channel pumps over common centrifugal pumps and the pump works better than I expected and as you can see here I can interrupt the water flow and then put this inlet hose back into the water aftera few seconds and the pump can still generate a vacuum and restore a good flow rate over time without completely drying out.

This capability is one of the main reasons why this type of pump can be used to pump a mixture of fluids into gases such as water and steam, as it is often needed in industrial processes and I remember this looking thing. strange here. I knew from the beginning that it was incomplete but it seemed very sturdy and I had never seen anything like it, so I still took it to the shop after cleaning it. By removing these three nuts from the bottom a little and unscrewing the front panel, I was able to separate this thing and now we can look inside mounted on a very heavy cast iron base, we found three leaf springs and some kind of electromagnet. and with this information I was able to discover what it is, it is a vibrating device in German called zeb Shuttler or Shuttle Tour, the term in English could be vibro sifter or something like that and the idea is that a tower of sieves is stacked with descenders. grid size on top of the vibrating part of this machine and then you can just shake these sieves automatically, apparently this is used as lab equipment in the cement industry for example, any good ideas what else we could use this for in the workshop?

I thought about sifting shot blast media from a shot blast booth for example, let's take a look at That digital audio recorder is really a rare find and I've never seen one of these players in a thrift store or flea market before. , one reason is probably that they are quite valuable. 10 euros is a ridiculous price for this unit. and I was very lucky if I can fix it of course this unit has a label that says "bustler" and that is just a euphemism that translates directly to "handyman" and translates as plain speaking which simply means "defective", "defective" ", "doesn't work", if you ever tried.

To buy anything in Germany online, you may have come across the term bustle before, not only when it comes to electronics but also cars and even houses, and it can really mean anything from a minor problem to a lost case. , in this case the tape drive just doesn't open when you press the eject button and after removing the sticker and tape with a plastic scraper I open the case, it actually doesn't look that bad here, there is no dust nor signs of previous

repair

attempts, as you can see the mechanism that pushes the tape. First it lifts down but then it doesn't eject and the reason is quite simple, apparently the motor keeps turning but the little rubber belt here is so worn that it just slides so the larger pulley here doesn't even move more in order.

To replace the belt, we will first have to remove some gears. To do this, I first unscrew a small screw on the top of that steel washer that holds the big white plastic gear in place, and by depressing this mechanism, I can pull it. That gear underneath we find another intermediate gear that also needs to be removed here temporarily. I was now able to open the ejector mechanism manually, making it easier to access the motor. I removed the old, worn strap and have recently rediscovered my interest. Meanwhile, on old audio repairs, I made sure to stock up on replacement belts and installed a new belt which of course has to be a little tighter than the old one, let's see then if the mechanism works and looks pretty good, even the cassette.

It appears to be playing, but we won't know for sure if it actually works before trying the playback and recording functions for that purpose. Now I have connected the player to the amplifier that we repaired in the last episode, which by the way was episode 27. It is episode 28 and all the other episodes are linked in the video description below this video, but what is really in that tape that came with a device? Well, the former owner must have been a fan of traditional Bavarian music, by the way, what is that? Well, Sony introduced it. digital audio tape in 1987 and reached the film and professional recording industry, but never existed in normal homes.

As far as quality is concerned, it is said that this format can offer higher quality than CDs, depending on Of course, but it also comes with the added benefit of being able to record, erase and re-record, etc. and since it's a digital medium, lossless copying is also possible, and speaking of recording, let's try that too. I have now plugged a tablet into the input of the deck and as I have recently been playing around with composing electronic music on the tablet, we will try to record some of that onto tape and that works fine too, quite a unique and lucky find in my opinion Lastly, but not least let's take a look at the brown stereo system, to be more precise it is a brown audio 300 manufactured around 1969 and this is another exceptional find because it is a highly sought after collector's item and similar devices can be found in museums. than in thrift stores, this book titled Brown 50 Years of Product Design shows how German electronics and appliance manufacturer Brown revolutionized product design in the 1960s.

One of the main influences here was the team behind by german industrial designer dieter rams. I've been a fan of the design but also the exceptionally high quality standards of Braun at least at that time and we've encountered brown audio devices on this channel before, like when I repaired this 1957 music console a few years ago. A link to that is below in the video description and what about the 300 audio unit itself, although the device appears to be in very good optical condition and upon turning it on I briefly test the radio receivers and this is always a difficult thing to do on video because I will have copyright problems. with youtube, when I record music that plays on the radio while I film, but there doesn't seem to be any problem with the receiver and amplifiers, let's try the turntable and just like with radio shows, I always have to choose something that is more It's strange that I don't encounter copyright warnings here too and that's why I have to go with the popular groy record in stereo sounds.

In stereo, with this edition focusing on field recordings of boat engine noises and other maritime sounds, it is clear that the turntable is spinning too slow to fix, I will replace the drive belt and see if that helps at all. I first remove the clear cover for that purpose, there are two hidden screws on the back, each of which has an irregularly shaped screw head that when turned a few degrees will release the lid hinge mechanism when lifting it from the actual turntable table we can now see the old belt and it can be removed easily.

It wasn't hard to find either. a replacement belt online and I installed that depending on the state of degradation of the old belt it may or may not be necessary to clean the surfaces of the pulleys and here we can see how the speed adjustment of this turntable works a small motor has a brass pulley with four steps of different diameters installed on the motor shaft, then a height-adjustable rubber friction wheel can make contact at four different heights you can choose from, in addition, a copper disc is also installed on the motor shaft and together with an adjustable radius permanent magnet it forms an eddy current brake which can be used to adjust the rotation speed in addition to the four base speed settings and with the new belt installed I can now play the record at the correct speed, but while I move this unit I can hear something else is not right something is loose it sounded like a small piece or something is moving inside the cabinet to open the cabinet I will turn the whole unit upside down because I don't want to damage the turntable and other sensitive parts At the top I'm improvising a wooden stand I'm using some smooth pieces of 2x4 and the old wooden plate from one of the workshop cards before I turn this device over I also have to remove the term board and some underlying parts parts after doing that now I can also see what could be wrong here it looks like a piece of plastic has broken here after securing the turntable arm I proceed to unscrew the bottom cover another unusual thing about brown audio devices in comparison with most other manufacturers is that the various sockets for external sound sources, speakers, etc. they are hidden at the bottom, they probably did it for optical reasons, but it's not particularly practical when you move these things, we often take a look inside and here in the corner is the mains transformer.

It is the voltage selector, as you can see, it can optionally operate on 110 volts, this is a fuse and here we have one of the complete rectifier bridges and also some electrolytic capacitors on that same board, this connector is typical of the brown equipment of the 60s this was one of the first brown transistorized models but these connectors are actually vacuum tube sockets the brown ones were used as multi-pin connectors and sockets after vacuum tubes were already gone and you can find them here in various places, here are the two power amplifiers for the left and right channel with the large heat sinks and here are the old German din type connectors for the speakers, the second turntable, the recorder, as well as the am and fm, this is the set of variable capacitors for the fm tuner, here are the actual tuner circuits and We can see that the rubber bands holding the ferrite antenna on have become brittle over time and by looking around here I was able to find the little piece that had been broken.

I glued it back into place and at least for now the mechanism works again. I'm pretty sure that sooner or later I'll do a little more to preserve this beautiful piece of history for the future, but for now there doesn't seem to be any major malfunctions, so that's what I had to show you for today and as I always hope You enjoyed it and if that's the case, please like this video and let me know that I should do more of these repair mara
