Man, you are really different from all these fancy "makers". Thanks for the content, despite the financial constraints. Edit: I just became a patron. Thanks mate

"Don't turn it on, take it apart" fantastic. This is how I do it too giving myself plausible deniability that my work didn't break it.

Yay, you're back...scrapyard find makes my day!!!

I know firsthand the time consumed with repairing and rejuvenating all manner of tools, appliances, and other equipment. I'm really glad someone else out there sees the value in keeping these things alive for an extra period of time.

Don't worry about talking about your private life, most of us have one and they always get in the way.Even though I am a novice and find my mind wandering when you start drawing schematics I do understand the basics of electricity. I thoroughly enjoy your videos. Please continue to do them.

9:00 I think this attitude best describes the inventor/repairer. You don't always have the right tool for the right job, sure it would be make life easier to have the right too, but sometimes you just gotta do what you gotta do. I LOVE IT. If I get this new job, I'm totally giving you a chunk of my cash so you can make more things.

The toolboxes were what I used when I worked as an agricultural fitter in the 70s. I only knew of one person who had a different one, it was just an oblong with a homemade tray inside, it was almost a meter long x 30 x 25cm and had two handles on the ends.

22:29 Similarly, I repaired checkout stand conveyor belt systems for a major grocery chain. The belts were powered by a General Electric 1/3 HP motor, whose failure mode was always caused by the die cast flywheel weights of the centrifugal switch breaking. The motors were expensive, and removing and replacing these motors was a very difficult and time consuming task. So I tested one of the failed motors to determine how long the start winding needed to be engaged, which was about 2/3 of a second. I bought a bunch of time delay relays from an electronics surplus vendor, which were programmed with a single external resistor. A junction box, $20 relay, a few wires, and an hour and a half or so of labor was all I needed to repair the machinery. The management was very pleased with this, a major cost reduction and much shorter downtime hours.

I’ve never thought of supporting anyone on KZfaq. But I’ve been a follower as long as I can remember. I believe you will be the one and only I support. Keep up the great work

That's a thick-wall bit of pipe! Chopping up a gas bottle (once it's ***well-ventilated***) works very well for this, and the ID of the refractory lining can be formed with thin ply. Fireclay is really sticky, awkward stuff, but cheaper than proprietary furnace material.

I love these scrapyard visits!

I would not have thought of replacing the centrifugal switch with a delay. Of course, I wouldn't have had the faintest idea how to build the delay anyway. Thanks for sharing--Glad to see you back.

Even cleaning up the basement of the old house would've been an interesting video on it's own.

Your explanations of the electronics are really clear and helpful, thank you. My condolences to you and your partner.

Scrap yards are an adventure. It's amazing what is just thrown away.

What I love about your channel is that you are just you being YOU, and not trying copy off others or hopping on some banwagon. Also you are good at explaining yourself clearly and you are good at keeping your videos interesting, I feel like I am learning something new every time I watch one of your videos. So good to have you back, can't wait to see more videos from you!

The delay circuit for motor start is one solution. Another would be to find (or make) a two-stage rocket starter switch: press down and hold on the “on” side to start the motor, release for normal operation, then flip the other way to stop. Or just use a push button to manually start, in addition to the normal power switch.

It's great to find someone who is doing your own thing and not reinventing the wheel, Here's a tip for you when using second hand steel mark out your job ,then grind your marks away , remark and then cut you will have a nice neat cut and it won't blow out Cheers from Australia

I love the old, blue, German tool boxes, which can be found at the flea markets for only a few euros. I bought a few and use them to store my extra tools. They are still sold brand new at home improvement stores like Bauhaus.

I've been a machinst/mechanic for 33 years. I love all things mechanical. I just wish I had you're understanding of electronics!

3:10 those helical items with interior splines are extruder screw elements. They are normally a high quality steel if you want something neat to forge.

Denn Schleifbock mit einer DIY Elektronik zu reparieren ist schon cool. Danke für das Video.

Copper in an Iron cruicible tends to make a hole really fast ! I lost my iron cruicible the same way.

Hello Post Apocalytic Inventor Been following you for several years now - you taught me so many things! Thanks for that, and please PLEASE keep doing that. Greeting from Southern Denmark (former Nord Schleswig you might say here 100 years after 1920)

23:05 a bridge rectifier or A FULL BRIDGE RECTIFIER?

Hey thanks for taking the time to draw out why you replaced that centrifugal switch with a delay circuit!

On home refrigerator compressors, the usual capacitor start circuit is a relay with a PTC "relay". No moving parts and very reliable. This would probably work for your grinder.

i got round the weight problem by purchasing a recovery transit with a palfinger crane on it, great toy

Mouth watering tool haul ! ! ! I wish I be there.you r living in "paradise" ! ! ! if i have power to fulfil my wish,I have only one wish which is,I own all of these so called "junk" and "scrap". God bless you.

I have the same kind of bench grinder, it's marked as "Ferm". It's giving me already 15 years good service after I acquired it second hand. Good to know there is a capacitor underneat !

I love this video series, it's great to see these things repurposed!

A palm sander makes an excellent vibration source for packing concrete, portland cement, etc. Make a wooden or plastic cover, use a peel and stick velcro and you are in business

To protect that board and solder joints...spray or dip it into some polyurethane...once it dries it will not only be better waterproof but also better protected from shorts Very cool setup on that grinder! and boy howdy if you can melt cast iron with that foundry it is pumping out some heat!!!!

New guy here, I repair Plastic pipe welding machines that are built in Ditzengen so I understand your drawings, Love the channel.

I got a kick out of you calling SOS when testing the switch. Too funny!

Nice! My approach with the Bench Grinder would've been a 3-way-switch. You know like the ones for big 3 phase Machines which start in "Star" and then go to "Triangle" just so it would be "with Capacitor" for starting and "without Capacitor" for afterwards...

Finally another video of yours! I couldn't wait any longer! Nice to have you back. Nice video!

Of course you can disconnect the starter winding completely and just give the motor a spin by hand and then apply the power. It will come up to speed and run fine. You can run it in either direction. The start winding just insures that the motor starts in the same direction. Manufacturers use a small gauge wire for the start winding to save money and switch it out once the motor starts.

It's nice that you have a scrap yard that will sell to the public. I was dropping off some scrap at a scrap yard once, and saw that someone had scrapped a set of Ping golf clubs. Perhaps a wife, perhaps a frustrated golfer... who knows. I tried to buy them... No luck. They only sold scrap to smelters, steel mills, etc., no retail sales. The only scrap yard I have found here in the US that would sell to public are automobile scrap yards. I would suspect there are others... I just haven't found them.

Wow! Excellent mixture of recycling and rebuilding. Thx for sharing 👍

Greetings from the Pacific Northwest USA! Love to see creative uses from old stuff and old stuff brought back to use! Look forward to more!

I’m now a lot more curious into fixing my bench grinder. It has a long history (decades) of never starting without a quick flick of the wheel before turning on the power.

That grinder repair was life changing. You sir a bit of a genius. Thank you for videos. Please keep making them.

Grinder modification is just amazing!

Missed you and your videos mate. Was good to see another video appear on my subscriptions

PAI rocks!! I actually find it a bit disturbing how anyone can give this guy a thumbs down, even though it’s about 0,01% who does. I wonder what these geniuses have done that makes them so self entitled to criticize the huge effort that this guy does to make scrap valuable tools.

I very much enjoyed the part about building the starting relay. A "poor man's" solution to the problem that I have used several times is to disable or disconnect the centrifugal switch and install a momentary "on" toggle switch or button in place of it in the starting circuit. To start the motor activate the momentary switch, turn the main switch on and then release the momentary switch when the motor comes up to speed. Kind of primitive, but it works.Another solution is the "one size fits all" SUPCO APR5 relay which can be made to work with most capacitor start motors under 5HP. Keep up the good work.

Man, your solution for the capacitor issue is what I call over engineering LOL

You might want to add an LED that shows whether the run capacitor is in or out of circuit, so if a failure occurs that you have a chance to notice it before burning out the motor. I really like the reuse / repurpose / recycle styled videos. subscribed!

blue tooloxes , gotta love them ! you get better ones from the scrapyard than i buy !

Welcome back. You were missed. Learn so much from you. Keep up.the good work and the videos coming!👍

Schönes Video! Mir hat vor allem der Part in dem du die Schaltung erklärst gefallen, gerne mehr von sowas! :)

Do you realize just how fortunate you are having access to these scrap yards. I could only DREAM of such a day.

I love watching your channel. Your welding skills look great and your videos are educational. Even your ability to create your videos in two languages is incredible. You are an inspiration. Frank

I like that centrifugal switch replacement. Almost makes me want to do it myself on a nice 80 year old induction motor on my good table saw - the centrifugal switch got tangled up in the wiring and flew apart.

Your torch settings are a little hot for plate steel that thin. Also drilling holes along your cutting line hampers the rapid oxidation process. The finished product is undeniably impressive.

I really wish we had scrapyards like that here in San Diego.

Great video with scrap yard visit and more complex electrical stuff explained well.

Be careful heating galvanized/zinc plated metals to critical temperature. The zinc coating off gases are toxic when brought to those kinds of temperatures. I also recommend using some sort of fibre glass strands, or chicken wire as a reinforcing binder the next time you pour refractory to line your foundry.

Great to have you back, really enjoy the videos.

very nice video with detailed schematic and photos in a step by step manner so instructive! i just found your videos since those of the stereo/boombox bluetooth hacks. love to do repairs! thanks for making me understand so much stuff.

Well bigclive once took apart an starting "relay" for I believe an washing machine. Basically it used an optimized PTC element to run the start winding only for a short time. After that time it suddenly went high resistent and passed only a few miliamps to keep it in that state.😁

I used a three position selector switch, Off, Start and Run. Very quick and easy to do.

Good ol' 555 timer! Incredible how useful they can be. :D

WOW! Who would throw out a lathe that big.

Welcome Back ! Love the Scrapyard Finds and Repurposing Tools and Equipment .

I always enjoy watching that stepper drill bit in the intro.

Das war ne clevere Idee mit dem Start-up-Timer. Danke fürs posting! Sowas ähnliches kann man dann auch z.B. für einen Kühlschrank Kompressor nehmen wenn der PTC durchgebrannt ist. Nehme ich mal an.

Outstanding presentation! Your commitment to educating the viewer brings your offerings to center stage within the KZfaq community as a leader in how to and why. I, like thousands more, look forward to your next presentation. What a community you have created, worldwide...

Im sooooo glad, there is a new episode coming up... I really appreciate your work I am always learning something thanks to your skills and knoledge. Also Quite like the way you explain things and give background information integrating it very skillfully. Am already looking forward to the next episode.

Thanks for the share. Great scores!

As well as removing the moisture from the cement, the fire will give your smelted metal a nice smoky flavour

I was given a new grinder, had the same problem, the switch was loose on the shaft. Readjusted and tightened it and it worked. Another on had a burned out motor, I took out the windings, cut a hole in the back of the housing, and put v belt pulley on the old motor shaft driven by another old motor.

I love your channel and this series, so glad your back

Your forge experiments were interesting. In casting metal in a mold you can release bubbles in the plaster with vibrations I'm assuming the same thing would work on concrete. I didn't want the forge experiments to end lol too much fun in the video.

Beautiful solution for the broken centrifigual switch. On some of my electronic projects, I used 555 chips to energize relays with time controls.

An even simpler way of replacing the centrifugal switch is to have a "press and hold to start" switch. Your way is nicer though :)

I'm really enjoying this scrap-repair series, looking forward to seeing more.

That's a great solution for the starting circuit of the grinder, however if you were to stall the grinder, it will not start up again. You will need to turn it off, then back on to restart.

Yes! I love these videos, I always save them for the time i can sit and watch them in peace. :)

I'm eager to see the rest of the foundry build! You do a great job of explaining all the steps.

It's so good to see you back again. This is by far one of my favorite channels. Not only are your projects interesting and fun to watch as you progress from idea to completion, but I always come away feeling as if my mind and knowledge have been stretched and exercised a bit. Keep up the good work!

I remember when i was living in Baumholder we had scrapping days when every one put large heavy non recyclables out and we went skipping

I like your videos and your take on the scrap industry. I have a few dowidat spanners here in Australia. I also love to find old tools and fix them, although no where near your level. I've let the smoke out of a couple of things. All the best.

I had a capacitor fail on my table saw in the middle of a project. For a while I started the motor by lifting it off of the belt and pulling on a cord that I wrapped around the pully - old outboard motor style.

New subscriber. Thank you for saying "auxiliary" correctly! No one does.

Super work! It is an eye opener to see: How (what is now) a very simple and cheap circuit, replaces a complicated and prone to failure mechanical devise. Thanks for your videos.

I do like this series quite a bit. Wonderful narration.

I really enjoy the electronic fixes for these. That's brilliant.

Yes! Glad to have you back!

wieder was gelernt... du schickst mich immer wieder auf die Schulbank... danke dir :)

Belated wishes for 2020. Glad to see that you're back 'online' . Regards from S Africa Clive

I love the repair-a-thon series. But unfortunately here in Czech Republic according to the local law, it is banned to buy scrap from such places like scrapyards or recycling places. You can only change scrap for scrap but then it doesn't make sense anymore, since you no longer reduce the amount of waste...

You sir having an amazing electronic and circuit designing ability

I learn so much from your videos. Thank you!

You should take the time to make wooden tool boxes, if you love your tools, then the tools won't rust anymore, as they do in a steel toolbox that is always damp. Great channel and videos.

Love these videos

You probably had the copper/zinc from the brass defunding into the cast iron, thus creating an amalgam of lower melting temperature. Which would mean that the bottom of the pot never really reached the melting temperature of the iron.

Thanks for sharing. I really enjoy watching your videos. They are very entertaining, interesting and I learn a lot as well. Your work is appreciated.

Welcome back. Excellent mix of topics today. Thanks.
