Terrific Scrapyard Finds! Repair-A-Thon! 

Hey guys! My last video was one of the longest and most elobrate ones, I have made so far! You should check it out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ba3JjHmCB80.html

You are so lucky to have access to good quality scrap at cheap prices from your scrap yard, many yards in other countries do not sell to the public. Keep up the great work.

Love your philosophy on needless waste. Only wish I had your electrical skills.

These videos are like watching a friend you’ve missed for a few weeks. Great as always and stay safe

In the UK, 110V tools are common on building sites. They are fed by an isolating transformer. But the secondary is 55-0-55v The centre tap being the protective earth. So the highest voltage in a fault condition should be 55VAC.

i think the spring in the electric saw is there to prevent you from hitting hard objects and prevent damage to the chain while cutting like the ground or a rock or perhaps your body just be careful when operating it

Here in the UK we use 220/240 v but on building sites and most industrial sites we use 110v or rechargeable tools , the transformers are yellow plastic boxes filled with sand for cooling and protection.

“The spring is there for a reason.” I can’t help but wonder if it’s there mostly so that it can break.

You can drill aluminum plates with regular bi-metallic (variable pitch) hole saws, you just need to apply less pressure and work slowly, dipping the cutter into an oil can every minute or so to keep it from overheating.

So cool that you get all that industrial scrap where you are. Around here it's just rusted out cars and appliances.

The Hitachi 9" would make an ideal static cut off saw for the workshop. Its a bit cumbersome with the transformer to be very portable lol = ) Hurts my heart to see the old workshop tooling in the scrap yard = (

That house at 1:55 ... I know it would cost a fortune to fix these up but what a cool house

I liked your electric chainsaw solution. I think another option preferable to the fragile spring would be an aluminum shear key. This should be more durable than the spring and theoretically still shear off in the event of a jammed chain for safety purposes.

You can tell you really love this stuff, you get me coming out with old engineering-isms. :o) happy days.

I 100% agree with your decision about the chainsaw. It would be one of the nylon gears that would fail anyway. You are best having angle iron (as you have used) rather than “U” shaped metal for the rear door of the trailer, as it would hold water and encourage wood rot. Great work.

Ooh, injection-molding machine, maybe? Whoa, a torched street-sweeper! Ouch. More machine-tools, unknown type. Great projects, finds, and video! That's a sad old vehicle rusting in the bushes, looks like it burned once as well.

I'm like you, I used to go to the local dump and lament at all the stuff people threw out. It got crushed and buried. What a waste. I think people underestimate the local scrap yards as a source of raw materials.

You got a Seca scale! Good on you. A old, German and family run little company dedicated to bringing forward amazing and robust scales.

Scrapyard repairathones are without doubt the best videos on youtube.

When I visited Germany, we toured around a lot in a hurry. The one part where I was bored for a couple of days and got to relax and wander was in the pretty plain town of Neumuenster while mum was at a horse event. I was intrigued by an abandoned textiles factory. Around 5 stories tall. Full of furniture, machines etc. While far from unheard of, with property values high and a growing population, abandoned properties are pretty uncommon here in Australia. What is around, gets thoroughly trashed quickly and inevitably demolished and redeveloped.

Another Awsome Video! And the Spring in the transmission of the chainsaw is there to avoid the big Push forward if the chain gets blocked/clogged/stopped while inside a tree for example. If that happens without the spring on the transmission the pull is instantaneous and very strong. But it should work ok as long as the user is aware that if the chain Blocks he must remove instantly the finger from the motor switch in order to avoid getting a strong push/Digg forward on the chain. OH ! And even more interesting I just remembered: As the gears are made of plastic if there is no Spring to dump initial angular momentum (Torque) ..then ... those gears will wear out Much Much faster then if they had the Spring linkage! There ya go ... But it is indeed sad to see how things are made with obsolescence in mind, and of course spare parts are not even provided many times. I once have seen a Samsung TV repair manual that had No schematic whatsoever and most of the parts from the TV frame say : NSA ...No Service Available ... that is Samsung did not provide replacement parts. Their argument was: If those parts break the TV is not even worth repairing ...

I'm a big fan of your initial philosophy and my feeling says: why does the hardly-used chainsaw even need a new chain? You can get them maintained and sharpened for just a few euros (or do it yourself)! I'm sure there was a good reason for doing so.

While the chainsaw spring was designed to save the plastic parts from shock, it is disappointing that someone at Bosch decided not to sell it separately.

You are so good at what you do on a small scale of modification and repair that I think you should consider buying a used truck or van and creating a post-apocalyptic survival vehicle capable of using multiple sources of power. Your first efforts might not be street legal, but it would give you a lot of experience as a testing platform for ideas.

Great video! You can always smarten up the trailer by clipping on some wheel trims and painting it some more.

Great work Gerolf , I did my first scrapyard hoard last month and brought back Facom spanners, huge tapes and heavy load hooks in a matter of minutes, I can't wait to go back. Nice to see that the Subaru is still going strong ! Cheers )

Regarding the saw, if I am not mistaken, that spring is a safety feature to prevent backlash. When the chain gets caught, the gear will slide to the side detaching the motor from the chain. That is why the spring is not very strong either. A strong spring wouldn't let the gear slide so easily. Someone must have abused it for it to brake. Bosch (/Siemens group) over charging for a set instead of selling just the part is just typical. It is almost their way of saying "don't brake it".

For outdoor welding flux core wire is the way to go for thinner material, and easier than stick for the novice.

Another inspiring video rising against the notion of a throw away society! I had that Hitachi grinder from my own salvage trips. It is pretty good for the money although I wish it were Japanese made still. It performed much better on my USA style mains power.

Damn some of the things you say can be made into awesome inspirational posters and desktop wallpapers. I love these Repair-A-Thon videos, its like sweets at the end of a long hard day, SO DAMN GOOD!

Hey I don't blame on the hinges, I would've done the exact same thing! Why waste money replacing them when you could easily fix them yourself. I mean that's basically what this channel is all about, repurposing and fixing things to give them new life. So I'm here for it! 👌 Great video and thank you for uploading! 👍👍

I hear what you're saying, Gerolf. Function over fashion, whenever possible. Thanks for showing the process.

Went on a fixing binge from a local thrift store discard pile. So far fixed a pressure cooker, an induction cooker, a ninja cofee pot, several lithium batteries, and a shop vac. 🤪

I think the spring in the chainsaw exists to mitigate shock transmission to the motor. Not surprising it was broken considering the chain was fitted backwards when you found it hehe

I upcycle and recycle as much as I can, but you are in a class far above me, more people need to watch your videos!

Thanks again for posting! I always enjoy seeing your new videos pop up. :D Might want to tell people to be careful welding galvanized stuff. Zinc fume poisoning is no joke.

Those toroid cores could be current transformers. I had similar (just smaller) in some old Tyrack 8 series DC regulators at one of my ex workplaces. These can be cleverly used. Best Regards, and thanks for nice videos.

Always enjoy your content and philosophy on the repurposing of old but usually much better items than the disposable ones of today. With regards to the abandoned villages, I was merely pointing out how unsettling it was to see a town with no people milling about - creepy. You are quite correct about welding - it's never as easy as looks on RU-vid. Quite a learning curve but I've been able to experiment now with 3 different types of welding and finish my styroaircrete experiment repurposing Styrofoam with concrete and Drexel foam. Hope you and your family are doing well.

Yes these videos are entertaining and unique, not to mention well planned and thought out, just pure quality, keep doing them friend 👍

My favorite repair on a tool as new as 2 years is to call the manufacturer and request the parts. Some companies are very outsourced and it’s useless, some companies are remarkably accommodating.

Always happy to see a new video! Repair and repurpose! It's a way of life. Seems like regular folks just don't understand us. Glad there's a place to be encouraged and motivated. Thanks!

The goodness already starts with your fantastic intro. Please keep up the awesome videos!

When welding zinc plated steel, make sure you don't breathe in the welding fumes. Zinc starts boiling under the welding arc and resulting fumes are toxic. Also some zinc bubbles get trapped during welding and hence the resulting bead is weakened.

120V equipment is used on building sites, via step-down transformers. These have a centre earth, so each leg is only 55V which greatly reduces shock risk. Put the appropriate yellow plug on it and you could maybe sell it to a builder.

Thanks so much for everything you do. Your videos are always so enjoyable to watch, well made, and informative. I like your empathy for the machine. May the omnissiah watch over you

That poor Bosch chainsaw was doomed from the very start and so many like it of that design! When you first started taking it apart, I expected to see an actual small centrifugal clutch inside, but no. Not no but hell no type of clutch! So I say good save on that little chainsaw!! The other turn off was that there was so many plastic pieces inside to include a plastic gear! What was this manufacturing place was thinking of??? The chainsaw was only supposed to be used for pruning small branches to start with and it even failed that test when somebody jammed the chain, clutch and motor, only to break that spring, which you cannot even call the mechanism a clutch to begin with! Some of these manufacturing practices defy any practical uses now a days, that it isn't even funny any more! I say nice save on that trailer too!! Great work as always, TPAI!! Mega ditto's on your great works of repair and the reclaiming of old stuff! I have always taken such a stance on reclaiming and putting stuff back in newish like condition as best I can. I too have applied standards throughout my life and often I've found grief over it when my son and my sister just give me hell over it! A through away society is for the birds!!! My brother in-law used to repair stuff but he tends to just through it away!! Sometimes you can't even get him to change the oil on these small engines with the garden cultivator, the push mower, the riding mower, the pressure washer; you name it and he's just one wrecking ball! By the time that I end up with it, it's too far gone!!!

Capitalist entitlement is such a waste. We also never know what kind of toxic mess is left behind. I tried to buy a 50k square foot knitting mill in my hometown it had been empty since Henry Ford fired the owner in 1920. It burned down when fools started to retrofit the building in 2017. Your electronics knowledge is second to none on RU-vid. Made even better by the fact that it was someone’s trash Thank You

If you have both the old size and new size hole saws, you can nest them together on the arbor and use the smaller size as a pilot.

I feel ya on tig welding crap material in crap conditions. It never turns out quite the way ya hoped!

You dont have to explain your welds bro. Were all here in awe of your skills

From a much older video you mentioned wanting to open a shop for repaired tools. You also mentioned this would require more storage space than you have. Perhaps you might consider working with a local library to start a "tool library" I am in the US and tool libraries are becoming popular options. A real help for the community.

I had a chainsaw with the exact same fault and the exact same result looking for a spring! However I think the spring is actually a clutch so when power is cut the non driven potion of the shaft stops dead as a safety feature . When power is applied the spring 'winds up' and grips the shaft thus driving the chainwheel. I too thought of welding or sleeving the shaft or getting a spring made locally but, as is the case so often and in fact the point you make I bought a new saw.... I did however keep the old one to....'mend later'.....

What a super variable load you made, looks a few KW but Ill guess less as the radiation would melt the fan housings. Those chokes look perfec to use with jogging machine DC motors. Shate tree nature ? waste not ,want not ? What a treasure island you local scrapyard is, Machines like the bender and the green Eisele, what was that, hydraulic assisted drill ? Would make a great chisel morticer for gates and doors. Always difficult to move though. You chose your battles well. There must be a great temptation to strip all the pneumatics, valves and solenoids off every machine. There was a pride in buildings and architecture the factories of today cant afford, a pleasure to see. a bit of urban exploring. Enjoy what you do PAI.

I don't understand everything you do but I can pick up some good tricks and tips....Thank YOU

I was thinking the other day that if you have a push button that you don't want to accidently push, you need a guard on it. I've found that a cap for a PVC pipe with the end cut off gives you a ring to mount over the switch. Just glue it in place and there you are. I've used it several times and it works great.

Your power electronics projects always have FABULOUS enclosures. Hmmm... I want that terminal!

That grinder is quite a find, even if you had to make 110V for it. I'd also love to find a control enclosure like that and wire it into my home assistant somehow :)

US homes are actually wired for 240v but most outlets are wired for 110v but larger appliances and a/c units, etc will be wired for 220v. It's a common misconception that US homes are wired for 110v when they are in fact 240v.

Ah, another soothing story with a happy ending, a good intro and a promise of something more to come in the next episode. :) Now that's a video making skill! :) Cheers. :)

It's not too difficult to wind your own springs providing you can temper and anneal strong wire

That transformer was a chonky boy! Cool way to give it a new life. Maybe use the 24 volt tap for a fan to help cool the transformer.

Makers of springs are always battling the issue of hydrogen embrittlement when making spring steel. When this problem occurrs, the result is a spring that can shatter like glass when a shock load is encountered. I suspect that was the problem with the Bosch chainsaw clutch. Wrapped spring clutches like that are usually used as over-running clutches.

Ironically that weak spring in the chainsaw was probably there to protect the plastic gear in case the saw got stuck. 😂

The intro music brings me so much joy every time I hear it

I wish we had junk like that.... if we do I don't know where to look... Great video Thank you

This was a fantastic episode. I loved in particular the trailer renovation. I have trailer just like that (only a bit shorter in length) and I needed some ideas on how to renovate it. So, thank you very much and regards from Portugal.

I’ve loved your stuff and view on life for the last 10 years. Thank you mate

i hope you get some better weather for your activities. Keep up the good work, and teaching us new things. Thanks!

You seem to be an engineer of sorts. So useful for what you find. I thoroughly enjoyed your country side video and the two wheel tractor video. Great video.

Well done. My thought on the hinges was to epoxy rods into those channels, but your approach seems to have worked well.

Love the videos, rough and ready is what 95% of us do so keep on doing it👍👍

HI, regarding the bosch chain saw, check that the lubricating oil pump is not blocked, it happened to me that the oil, specific for chain saws, has crystallized, being of vegetable origin, blocking the pump in a couple years of non-use. The most annoying thing is that I had to completely disassemble the saw to get to the pump. In case of inactivity for a long time, I advise you to empty the tank of vegetable oil (the one they call ecological) and run the saw with mineral oil for a few minutes to remove residues that can crystallize

It's a shame that more of your generation don't think like you. Well done. Cheers.

You are the only channel that I don't watch on 1.75 speed. I like the lazy pace of your videos.

Being a resourceful person never gets old. Like you, I also believe in repurposing, repairing, and restoring items that others no longer have a use for. Thanks for the inspiration to keep the up cycling going.

You are an inspiration to many of us, thank you

Bosh has really gone down hill. I used to buy and own almost all my power tools kitchen appliances kettles etc. from them. Around a year or so ago i replaced my appliances and kettle and all of them have preformed badly and developed issues. shame they used to be excellent

Would be cool to see you imagine an apocalyptic scenario, say you need electricity to run a pump to irrigate a garden, and then build out the components from whatever you can fabricate -- solar, wind, hydro, ram-pump, whatever. Have you read Lewis Dartnell's The Knowledge? You might want to check that out.

I have built, repaired and upgraded trailers for years for use in tree work, the UK has a less stringent view on trailer mods. As usual your work is great and footage is worth watching. I have not used a TIG welder yet, the finish looks clean. Did you consider adding removable side extensions? In the past I have used trailers and trucks with Ply wood sheets slotted in to allow more wood chip to be loaded, commonly called "Greedy Boards". Cheers

That intro speech, was so well said. 👍

Thank you for turning down the gain on the alarm sounds, I watch these videos to go to sleep

I welded my Skil chainsaw few years ago and it is still working, not very safe but its free😊

thank you for sharing . wonderful to see things brought back to life

My grandfather modified his trailer, by welding square metal tubing on the outside metal wall. He made new walls, with other square metal tubing, that could be slid in the outside wall tubing, and fastened with some bolts :) Easy to take off when going for inspection. and put on later when needed.

A lot of good stuff in that yard there, that's a given...

Allways a treat to find a new video from TPAI

Trailer looks great. Functional and not going to fall apart soon.

Always enjoy your videos.

The connect to host thing is quite cool. I wonder what other things it can do. Some of that industrial stuff is quite cool. I would love to get my hands on some of the cool stuff like a set of those old clocks that one might find in an old school. Just some cool stuff!

0:30 almost makes me wanna cry to see scrapped equipment like that, someone could use it. There is a company buying up everything in Texas and sending it to India. Kinda a bummer for me since I wanted to find a good cheap vertical mill and lathe to restore but at least its getting used somewhere.

I love to see the process of repair and invention. I wonder if he has seen Lingour. Chinese girl that can repair anything. She goes way deeper to fix generators and other electric motors.

I wonder if your step down transformer would benefit from some forced cooling. Like a couple decent size control cabinet cooling fans. Slap a couple aluminum heat sinks on the sides of the core of the transformer and blow some air across it. Or if you wanted to go super overkill, bathe it in mineral oil. Thats what grid transformers here in the states are filled with for insulation and cooling

I feel your pain, in Australia, car trailers with any sort of braking system have to be inspected every year, my last one cost $300 for 1 years registration including the inspection fee.

Bosch spring = planned obsolescence

You can sell the 120v angle grinder in Ireland or UK for building site use as it is regulated at 120v and every power tool on a site is run of a 120v transformer.

Congratulations with passing 500K subscribers! Up to one million!

The channel is doing great congratulations, keep these great repair-a-thon videos coming, I learn so much from them.

I think you do not need to know how much we love this kidns of videos, belive me, it is my favorite. I am watching sometimes your videos so i can get ideas what kidn of project to start next. Keep going!

I enjoy your videos and appreciate your outlook on extending the service life of old objects. I also like hearing what the German terms for technical or industrial processes are; it's not the sort of thing my low-grade school German ever taught me. And while your English is clearly excellent, your excessive use of the passive voice brings back painful memories of high school English for me. ;) Anyway- keep it up! I don't have a large shop myself, so videos like yours have to satisfy most of my angle-grinding needs.

I hope someone will save that Muhr und Bender shearing machine. That saw, despite being a cheap one, actually has steel bucking teeth. My father's new Stihl chainsaw has bucking teeth molded into one of the side covers.
