I just donated to your channel. I’m retired, with a lot of time on my hands these days. By watching your channel, I’ve learned so much about things that I used to know and many things that are new to me and are absolutely fascinating. Please keep up your good work, and thankyou.
Rich Hagendorf, you rock. I tried retirement for a year, now money's too low to donate... Shame, really, I live about four hours away from him in Denmark.
Anyone that repairs or restores old equipment, know the struggles you go through when doing your videos. Those quick, five minute jobs that suddenly turn into hours if not days. Thanks for all your efforts in bringing these videos.
So much respect for the effort both to film and to fix. You are a machine yourself! I’ve watched your entire series many times over and I must say that you yelling “Yes Yes!! “ gave me shivers and made me so happy for you! Truly inspiring thank you :)
Your intro is a brilliant and insightful synopsis of the human condition... history blames the leaders, but individuals shape the carnage. Up to the 80's VolksWagens had oil based air filters... better than anything else... needed no cleaning or replacement for 10's of years.
At 20:00 that huge Turbine is a Water Turbine used normally on small river generators. Up to about 300KW I would say. The top of those external ring still show the closing mechanism of the turbine ... pretty neat.
@@excitedbox5705 I would like to see some more behind the scenes like failed experiments and troubleshooting too. I've learned a lot from his channel and find his whole process fascinating.
Nothing is ever easy. You got that. Thanks! This is great. I think you "flashed" the field in the AC generator. My guess is the remnant flux in the field had diminished to near zero and it wouldn't start generating enough voltage to do anything. Fifty years on the shelf will do that. These are good videos and the editing is outstanding. I've been fixing electric "fireplaces" recently. Hardest part is making a schematic and usually you figure out what is wrong while you are doing that. Keep on keepin' on! :)🙂
Another brilliant video TPAI! The oil you’re meant to put in the air filter is probably to make the metal filter-gauze sticky enough to trap particles and thus take them out of the air breathed by the motor. Road vehicles (and others) used such filters in the 1960s and 70s, along with “oil-bath filters” on some - usually heavier - vehicles. I enjoy all your stuff, always fascinating. Les in UK
Yes, the oil bath filters were used by all auto manufacturers back in the early days of motoring. They transitioned to the common accordion style paper filters around 1950, best I recall. Not so many dirt roads, no need to filter out the big chunks anymore. 🤣👍
19:19 "just figuring out how to disassemble something like this can take forever" i feel like this fact gets no where near the attention or recognition it deserves. making sure you can disassemble something without causing damage, in addition to disassembling that thing in such a way so that you know how to put it back together, are often some of the most time-consuming aspects of a project like this. thank you for giving lip service to these concepts.
As always an amazing video. Fun fact: back home in Portugal there was a factory building SACHS motorcycles licensed by SACHS and there is a huge cult around them with clubs and etc that do events. Really cool brand
I think what I like so much about your work is how it differs from everyone else's. You seldom just restore old equipment to like new or just repair to good working order In the spirit of the post apocalyptic inventor you have no hesitancy to discard old functions and modify parts to get good use out of the castoff things you find. The intelligent improvising is inspiring. It is what we all wait to see in your videos. and seeing you actually use the things you make from the stiff you find to work on the latest find is best part.
Very thoughtful intro! Thanks for the Sachs history lesson. I had only heard of them for motorcycle applications and didn't know their background. Keep up the great work and cheers from Eastern Canada!🍁
Dear Brad Crossman. The first time I heard about the brand was as a child. But in a very different context. The very famous "Fichtel und Sachs Dreigang- Nabe" respectively "3- Gang Schaltung mit Freilauf" was on nearly every common bicycle produced in the 1960/70/80's. At least in Germany. Please kindly allow me to suggest that you google it yourself if you want to see/learn more. 2) I watch a ton of utube videos. Some of my favourite channels are from Canada. Best regards, luck and health.
@@Chr.U.Cas1622 In the late 50s I used to have moped ( called Sissy) looked like a scooter even on the autobahn police took it as a scooter no tickets very reliable
there were a lot of Sachs, Hirth and JLO's in the USA early snowmobile markets, like from 1965 until around 1973 when they started using Japanese motors or branding their own like Ski Doo had done
Great work! I got a generator for free a few years ago that had no output and was able to repair the control board to get it working. Since it wouldn't be used very often I converted it to run on propane or LP gas. I bought a kit to do it but since you have the proper tools I think it would be easy for you to make an adapter to convert yours. The advantage is that propane never goes bad or gums up the carburetor. The only problem would be lubricating the 2 stroke engine since you can't mix oil with the fuel you'd have to use some kind of oil injection.
@@ShainAndrews Where I live ethanol free gas is $4.51 per gallon, propane is $3.36 per gallon but I can usually find it a litter cheaper. Propane has about 73% less energy than gas but costs about 74.5% the cost of a gallon of gas. So about the same cost per BTU. I have a 500 gal propane tank in my back yard that never goes bad. Could I store the equivalent 375 gallons of ethanol free gas? yeah it's possible but what a pain that would be.
Anyone who has tinkered with a recalcitrant engine or mechanism will know the frustration of trying your best to reactivate it and then finding that the problem is not cured. I am well aware of your efforts here and am always impressed with your multi skilled approach. You seem to have a good working knowledge of electrical systems, mechanics, welding, inventing, fabricating, carpentry, building ( I remember your video of the waterproof roof over your girlfriends departed Father’s 1st floor tiled patio) videoing, editing and many other skills including a large helping of patience. A true “Renaissance man” Keep going! your videos are inspiring and entertaining
dude.. your opening statements should be a book. your philosophy is so needed in these times and your perspective from Europe has much to teach us in the US
G, Your tenacity is inspiring. The information you provide in your videos is insightful and instructive. Thank you for taking the time to film your endeavors, create the videos and publish them.
I love your reactions when it finally works! I enjoy seeing the process and especially like seeing success. Thanks for sharing the whole, with failures, setbacks, and how you diagnosed the problem and ultimately "got it done"! Isolating the problem is smart, and you teach it well. I could go on and on, but will stop and just say THANKS for all the entertainment and education for those just starting out. (Just to say, I've done stuff like this forever, and don't learn a lot new, but I do really appreciate your content! I should probably do some videos and share too!) Bless those like you that take the time to video, edit, and share their experience!
I appreciate how tenacious you are, and your thoughtfulness shines in the opening comments. When you stripped down the large generator to its bare minimum you really provided a clear explanation of how electricity is generated. I don't think I would have understood it if you hadn't shown the struggles in the first part. Thanks for all your efforts!
500,000 Subs is within reach!!! I can't think of a Channel more deserving. It's entertaining, informative & responsible content is what we need more of. Congratulations in advance.
I like the cap for the exhaust, it keeps critters from moving into the motor and fouling it. It shows someone was really thinking about the kind of things that could go wrong.
This guy really is very good. The way he simplify/analyze the large generator was amazing! I myself sometimes recondition vintage stuffs from japan. Keep it up brother! Cheers from philippines.
Outstanding troubleshooting of the generator circuits. I was very impressed by your technique of simplifying the generator's circuits by eliminating all of the unnecessary and/or intermediate components. I do not understand much about circuitry but your logic is impeccable.
Working with A/C & refrigeration in New Orleans I get to take apart and put together parts quite often and I can tell you I live for moments like 27:40 & 100% agree with sentiments at 28:35. Sent a little something to your PayPal in appreciation for your efforts and excellence in content. Thanks, Gerolf!
haha the momnet you got it working and shouted YES!!! was just beautiful, good work i love this channel you get a history lesson some electronics knowledge , and some mechanical all in one just brilliant.
Nice work!! On old generators without AVR (Automatic Voltage Regulator) those transformers are used to compensate the voltage drop for the current draw! I have and old Honda EG1500 and it uses a transformer like those on yours. One coil of the transformers is where the live wire enters and exits making a coil that increases the magnetic field when you draw current from the generator…this magnetic field produces ac voltage on the second coil of the transformer that is then rectified and feeds the field coil of the generator compensating for the voltage drop. When there is no current, the second coil of the transformer have 0VAC and the 230VAC is only produced by the remanent magnetic field, that passes thru a resistor and bridge rectifier.
24:38 These Filters work without any Filter paper and use a metal mesh inside. The oil is sprayed on that mesh and later the dirt that is sucks in sticks to the oily metal mesh. Without oil these filters don't filter anything
You are very smart and methodical repair man. Job well done on everything in this video. Especially the big generator repair. Also very glad you put emphasis on how all these dirty jobs are not easy and fast. I know how doing things the right way is usually doing them the hard way.
What a struggle to get that generator working! Respect for not giving up on it. I barely understood anything of the electric diagram since electronics isn't my strongest field, but seeing your reaction when it sparked to life again was wholesome! Also, what just came to mind, have you ever looked into teaching? Since you really like making videos about the process and showing people what you learned and how you did it is already up your alley
he is teaching. Not just about electronics and mechanics but life lessons as well. PS. part of the problem was that you needed to have a big enough load hooked to the generator to kick start the magnetic coils.
this is the spirit of old school, pre-internet...I'm glad to see it alive and kicking in you: it is what made the previous generations so memorable, valuable, quality, desirable, needed...time well spent, like compound interest it gives back what you put in, unlike (anything internet).
I laughed so hard in happiness when you shouted out when it finally worked. Great work. So many times I have known that feeling. Great video and great find on the motors!
"And that I'm willing to admit publicly...." I've got my eye on you haha! I loved the intro man I would love to work to a common goal but I really don't see that happening in my lifetime. If it was possible to settle differences without combat that would be great. Been to Afghanistan twice as infantry and really saw the worst of human behavior. I did my best to actually help the people who lived there. Fighting an insurgency makes you paranoid of everyone which then makes them distrustful of you. I started treating them like neighbors and not potential threats and my experience changed. Made some friends I still talk to and at the time felt like I left my AO better than when I arrived. Since I've been out I solve problems without violence ever considered when previously it was often my first consideration. What I'm getting at is it forced me to open up to others perspectives and improved my critical thinking. Anyways man great video I love seeing old tools getting restored and is something I do myself when I can. Often times it ends up costing the same or more than new but the knowledge and experience I gain from repairing them I cannot put a price on.
I love your step-by-step diagramming that shows a circuit evolving. You are the only place I ever understand circuit diagrams from without tremendous effort. I think technical people often explain things as if they're showing a peer that they understand it, rather than are teaching someone who has never understood it. Like, yes, those explanations are good, if you didn't need them in the first place. The difference is context. You give context as to why changes are made, and how they take effect. Well done. 150s hours? Oh my.
Another excellent video! A note on oiling of the filter. It's not for preventing corrosion, it's to allow the filter to catch small particles as they stick to the oil inside the filter. Older VW beetles in the US had oil-bath filters which worked on that principle. They were simply a box with steel wool inside that was coated in oil.
I have to admit myself I do love these older Motors. I don't know what it is but getting him up and running just gives me so much joy. They were truly Built Tough and damn near indestructible. Please keep up the good work
I like your "Dog with a Bone" attitude it really is inspiring, same as your previous episode with the stubborn lathe face plate, you prevailed and the results are fantastic. Keep up the great work !!
Another excellent video! I certainly appreciate the time you spent on this and all of your other work. The trouble shooting steps are really great. I am learning so much as well which is what it is all about. Donations coming.
What a wonderful idea to adapt an old military radio generator into something more useful. I have a couple of old dynamotors and have been thinking about adapting them to charge batteries
I recognised it inmidiately. They're for the AN/.GRC-9 Shortwave tranceiver. Used to have the American version for m Angry-Nine Radio, it didn't work. Also needed is 1.5V for low voltage valve heaters and 105V for the receiver, thats what the second connector is used for. This comes from a battery so you can be standby without the noise of the generator. Personaly i always used a motor-generator running on eighther 6, 12 or 24 Volts to provide the 4 required voltages. Love to have such a generator. hope you keep them original.
19:24 I've never done anything like that, but when I have taken apart complicated shit, I usually just take a pic with my phone. that way I can reference if I'm unsure when putting it back together. Of course if a lot of the wires are the same color, and its not obvious from a photo exactly where they came from, you'll have to mark them first.
The air filter element on the larger generator is oiled not to prevent corrosion but to provide a sticky medium that captures dust particles. Older cars had the same technology. Very interesting video and your explanations and clarity and precision of language are appreciated!
Sachs engines are the best. I had two-cycle snowmobile engine, wankel engine, and rotary chainsaw. Every item worked just perfect. The material and design is first class, period. Shame I lent out the items and they never came home. Oh well, I still have memories of real quality machines. Thank you for an excellent video Sir. Job well done. Have yourself a Merry Christmas and A Happy New Year TPAI. Peace too. vf
I've had the privilege of working on several small motorbikes powered by Sachs engines. Very impressive little engines! I really wish they were more widely available here in the US. Excellent work on the large generator, I'm hoping it makes appearances in future videos. 🙂
Soooo very glad you got the big one running! I know the frustration of figuring ut how to make something work that was old and probably messed with by someone else (or myself and now I forgot). I was hoping you would take it back to the minimal basics. Congratulations1
Man you're amazing! I really love what you're doing here. It's hard work, and I'm loving to learn more about this fundamental technologies. (Also, I have a Sachs 50cc ciclomotor 😁) Cheers from Portugal!
That's what I'm talking about! I love it when hard work, perseverance(stubbornness) gets the job done. Awesome Effort! Respect! Keep up the Great work! Inspiring....
Wow. Just wow. That was a lot of work and figuring out what went where and did what. But in the background I was cheering you on knowing you could eventually get it working, and as usual you did. Greta job
Hi, I really appreciate you explaining the effort and time spent on this project. Too often RUclips videos gloss over this aspect and give a false impression of difficulty level, effort and time involved 👍.
Hi I find your channel very informative and educational! They say old dogs can't learn new tricks thats not true I'm 62 and still learning! Thanks M. 👍😉
24:45 I believe the oil is on the filter to have dust stick to it, it used to be a common thing on air filters. Your explanations are wonderful, keep it up.
Your intro was quite well written. I completely agree. And I love old military tech! So basic and functional, meant to be used and field serviced, always have those awesome connectors that do weird stuff and made to be worked on with a flatblade and an adjustable wrench. Or hammer.
There is a chain of tractor supply stores here in Canada called Princess Auto, the founder got his start selling military surplus after WW2. He often repurposed surplus by turning it into something that served a new purpose like turning military generators into portable gas stick welding machines of which he sold to farmers and engineers that needed to weld things in locations where there wouldn't be electricity readily available. inventive minds will always be needed to see potential in giving old discarded things a new lease on life, you remind me of this guy. cheers!
Thank you for the video, I like your philosophy that you stated in the opening of your video, I like salvaging tools and equipment, just because it’s old and so called out of date doesn’t mean it can’t function and even be repurposed, this world throws away to much, stay the course young man, you are doing great.
Hi , you just got this generators from my hometown in Balingen . Now i live in British Columbia Canada and watch you disassemble this units, what a small world .
Beautiful introduction my friend. First time ive seen a video of yours and that level of reasoning is keeping me here. Looking forward to the rest of your video
Good to see that you show us how much time and effort it takes! Feels like I'm brought along more on your journey. You always felt like some untouchable God fixing everything instantly, so good to see you be a little more human ;-)
Lots of people-good dedicated people- would have given up the task. You are a gold-plated doer Gerolf. The saying that my dad was known for was "nothing's easy", and he is shown to be correct every day.
Hi there, thanks for sharing your knowledge here on RUclips. I am well aware that repairing an item is usually very time consuming and in general not easy. I watch your channel avidly because it opens my mind. best regards from Italy
It's amazing that a 70 year old engine sounds exactly the same as a 2021 one my dad bought a few days ago. Obviously the manufacturing and lots of small details have changed, but they're still fundamentally the same. That distinct 2 stroke noise :D It also reinforces that the old ones are just as useful if in good working order, nice job.
ALways love watching your content and I agree with you about old military items being made with much more durability than things are made with our "everything is disposable" society. We need to get back to creating more durable things like back then.
I know 2 cycle from motor cycles. If you use synthetic 2-Cycke oil you can go to 40 to 50 to one and the synthetic oil does not smoke. This makes these motors much more efficient and less obnoxious. The synthetic oil also will clean out deposits and reduce wear on the parts of the engine.
Nice "Francis" you have there, as always a nice video, edition and material, MUST of us know how much work does requiered to do what you do. Keep the good work.
I really love your videos.. Wait.. That an understatement.. I totally enjoy your videos.. Everyone of them.. The day I can afford.. I'll Def donate to your work.. But in the mean time just know am a big fan... Keep doing it.. Your an inspiration all over the world
Thank you for the great content! The reality of military-based products is that they are usually of the highest quality and are built to last. I appreciate that you promote these for use instead of just collection.
Most US military equipment is built to only just meet the specifications which sometimes are marginal, unlike what is shown here which does seem very robust. What you can count on with most military surplus is that it saw proper maintenance in use and it worked properly when it was stored. Good storage isn't certain and some things decay with time so will need immediate replacement if they still function at all.
I just donated to your channel. I’m retired, with a lot of time on my hands these days. By watching your channel, I’ve learned so much about things that I used to know and many things that are new to me and are absolutely fascinating. Please keep up your good work, and thankyou.

this is the spirit of old school, pre-internet...I'm glad to see it alive and kicking in you: it is what made the previous generations so memorable, valuable, quality, desirable, needed...time well spent, like compound interest it gives back what you put in, unlike (anything internet).
I laughed so hard in happiness when you shouted out when it finally worked. Great work. So many times I have known that feeling. Great video and great find on the motors!
"And that I'm willing to admit publicly...." I've got my eye on you haha! I loved the intro man I would love to work to a common goal but I really don't see that happening in my lifetime. If it was possible to settle differences without combat that would be great. Been to Afghanistan twice as infantry and really saw the worst of human behavior. I did my best to actually help the people who lived there. Fighting an insurgency makes you paranoid of everyone which then makes them distrustful of you. I started treating them like neighbors and not potential threats and my experience changed. Made some friends I still talk to and at the time felt like I left my AO better than when I arrived. Since I've been out I solve problems without violence ever considered when previously it was often my first consideration. What I'm getting at is it forced me to open up to others perspectives and improved my critical thinking. Anyways man great video I love seeing old tools getting restored and is something I do myself when I can. Often times it ends up costing the same or more than new but the knowledge and experience I gain from repairing them I cannot put a price on.
One the best channels on RUclips. Lot of context and history of war gadgets. Fascinating.
I love your step-by-step diagramming that shows a circuit evolving. You are the only place I ever understand circuit diagrams from without tremendous effort. I think technical people often explain things as if they're showing a peer that they understand it, rather than are teaching someone who has never understood it. Like, yes, those explanations are good, if you didn't need them in the first place. The difference is context. You give context as to why changes are made, and how they take effect. Well done. 150s hours? Oh my.
Another excellent video!
A note on oiling of the filter. It's not for preventing corrosion, it's to allow the filter to catch small particles as they stick to the oil inside the filter. Older VW beetles in the US had oil-bath filters which worked on that principle. They were simply a box with steel wool inside that was coated in oil.
I have to admit myself I do love these older Motors. I don't know what it is but getting him up and running just gives me so much joy. They were truly Built Tough and damn near indestructible. Please keep up the good work
Your hard work payed off! Congrads! This is the kind of thing I have done my self in my 70 years of being a electronics tech.
As a person who use to repair welders and generators, I constantly felt confused and frustrated. Big kudos; You're amazing at this.
Man the amount of work you do is incredible!
One of the best channels on youtube
I like your "Dog with a Bone" attitude it really is inspiring, same as your previous episode with the stubborn lathe face plate, you prevailed and the results are fantastic. Keep up the great work !!
Another excellent video! I certainly appreciate the time you spent on this and all of your other work. The trouble shooting steps are really great. I am learning so much as well which is what it is all about. Donations coming.
What a wonderful idea to adapt an old military radio generator into something more useful. I have a couple of old dynamotors and have been thinking about adapting them to charge batteries
I recognised it inmidiately. They're for the AN/.GRC-9 Shortwave tranceiver.
Used to have the American version for m Angry-Nine Radio, it didn't work.
Also needed is 1.5V for low voltage valve heaters and 105V for the receiver, thats what the second connector is used for.
This comes from a battery so you can be standby without the noise of the generator.
Personaly i always used a motor-generator running on eighther 6, 12 or 24 Volts to provide the 4 required voltages.
Love to have such a generator. hope you keep them original.
Ah, the moment of joy when something finally works!!! Well done.
Well done Gerolf! Kudos for sticking with it despite all the annoyances. A true inspiration!
19:24 I've never done anything like that, but when I have taken apart complicated shit, I usually just take a pic with my phone. that way I can reference if I'm unsure when putting it back together.
Of course if a lot of the wires are the same color, and its not obvious from a photo exactly where they came from, you'll have to mark them first.
The air filter element on the larger generator is oiled not to prevent corrosion but to provide a sticky medium that captures dust particles. Older cars had the same technology. Very interesting video and your explanations and clarity and precision of language are appreciated!
Sachs engines are the best. I had two-cycle snowmobile engine, wankel engine, and rotary chainsaw. Every item worked just perfect. The material and design is first class, period. Shame I lent out the items and they never came home. Oh well, I still have memories of real quality machines. Thank you for an excellent video Sir. Job well done.
Have yourself a Merry Christmas and A Happy New Year TPAI.
Peace too. vf
Nice job as always and for showing how sometimes things don’t go according to plan and not giving up gets you there in the end
I've had the privilege of working on several small motorbikes powered by Sachs engines. Very impressive little engines! I really wish they were more widely available here in the US. Excellent work on the large generator, I'm hoping it makes appearances in future videos. 🙂
Just as soon as I become financially stable, this is going to be the first channel which I subscribe to on patreon 😁
Soooo very glad you got the big one running! I know the frustration of figuring ut how to make something work that was old and probably messed with by someone else (or myself and now I forgot). I was hoping you would take it back to the minimal basics. Congratulations1
Man you're amazing! I really love what you're doing here. It's hard work, and I'm loving to learn more about this fundamental technologies. (Also, I have a Sachs 50cc ciclomotor 😁) Cheers from Portugal!
In the second, last part of the intro these statues! Id like to see can you share the locations of the intro. We like to view them. Have fun gr lex
That's what I'm talking about! I love it when hard work, perseverance(stubbornness) gets the job done. Awesome Effort! Respect! Keep up the Great work! Inspiring....
I love how the parts and tools come with it. :)
Wow. Just wow. That was a lot of work and figuring out what went where and did what. But in the background I was cheering you on knowing you could eventually get it working, and as usual you did. Greta job
congratulations for sharing your thoughts on the beginning of every video...pure gold in my opinion,something like a guide for the young people!!!
Just discovered your channel! Very impressive skills and as a fellow engineer, I’m glad to see you putting this out there 😊
I really enjoyed the video editing on this one. The long black cuts between moments really helped convey the suspense.
seeing the struggle and then hearing your moment of triumph there really brings it home.
Hi, I really appreciate you explaining the effort and time spent on this project. Too often RUclips videos gloss over this aspect and give a false impression of difficulty level, effort and time involved 👍.
Hi I find your channel very informative and educational! They say old dogs can't learn new tricks thats not true I'm 62 and still learning! Thanks M. 👍😉
24:45 I believe the oil is on the filter to have dust stick to it, it used to be a common thing on air filters. Your explanations are wonderful, keep it up.
Your intro was quite well written. I completely agree. And I love old military tech! So basic and functional, meant to be used and field serviced, always have those awesome connectors that do weird stuff and made to be worked on with a flatblade and an adjustable wrench. Or hammer.
There is a chain of tractor supply stores here in Canada called Princess Auto, the founder got his start selling military surplus after WW2. He often repurposed surplus by turning it into something that served a new purpose like turning military generators into portable gas stick welding machines of which he sold to farmers and engineers that needed to weld things in locations where there wouldn't be electricity readily available. inventive minds will always be needed to see potential in giving old discarded things a new lease on life, you remind me of this guy. cheers!
Thank you for the video, I like your philosophy that you stated in the opening of your video, I like salvaging tools and equipment, just because it’s old and so called out of date doesn’t mean it can’t function and even be repurposed, this world throws away to much, stay the course young man, you are doing great.
Hi , you just got this generators from my hometown in Balingen . Now i live in British Columbia Canada and watch you disassemble this units, what a small world .
You are a shining star here on RUclips. Thanks for all you do.
Love what you do! I donated a few euros also - keep up the good work!! So many of us live vicariously through you!
Beautiful introduction my friend. First time ive seen a video of yours and that level of reasoning is keeping me here. Looking forward to the rest of your video
"Will it run..?"
lolol
I guess you couldn't help poke fun a bit.
Your channel is awesome.
Loved that fast spark plug change. Your experience and intuition at work.
Good to see that you show us how much time and effort it takes! Feels like I'm brought along more on your journey.
You always felt like some untouchable God fixing everything instantly, so good to see you be a little more human ;-)
Lots of people-good dedicated people- would have given up the task. You are a gold-plated doer Gerolf. The saying that my dad was known for was "nothing's easy", and he is shown to be correct every day.
Hi there, thanks for sharing your knowledge here on RUclips. I am well aware that repairing an item is usually very time consuming and in general not easy. I watch your channel avidly because it opens my mind. best regards from Italy
No better feeling than struggling with technical problem for weeks and then finding the solution, cool projects as always
18:15
Wow! Not only did that start on the first pull, it started up sounding so good. Not even a warmed up chainsaw starts purring so smooth..
The oil in the air filter is to catch dust.
K&N filters for cars are similar. An oiled paper filter element that you wash and oil.
It's amazing that a 70 year old engine sounds exactly the same as a 2021 one my dad bought a few days ago. Obviously the manufacturing and lots of small details have changed, but they're still fundamentally the same. That distinct 2 stroke noise :D It also reinforces that the old ones are just as useful if in good working order, nice job.
ALways love watching your content and I agree with you about old military items being made with much more durability than things are made with our "everything is disposable" society. We need to get back to creating more durable things like back then.
I know 2 cycle from motor cycles. If you use synthetic 2-Cycke oil you can go to 40 to 50 to one and the synthetic oil does not smoke. This makes these motors much more efficient and less obnoxious. The synthetic oil also will clean out deposits and reduce wear on the parts of the engine.
Nice "Francis" you have there, as always a nice video, edition and material, MUST of us know how much work does requiered to do what you do. Keep the good work.
The Monument to the Battle of the Nations in Leipzig at 1:40. Vielen Dank für Ihre feinen Präsentationen.
I can definitely say that I fully understand the effort you put into this video. Thanks.
Your hard work and passion is great to watch, thank you for another very enjoyable video.
11:57 if you dont have shock absorbers you can print them out of TPU on your Prusa i3
HI from Australia. Thanks very much for these awesome videos. you are an inspiration to us all 👍👍
I really love your videos.. Wait.. That an understatement.. I totally enjoy your videos.. Everyone of them.. The day I can afford.. I'll Def donate to your work.. But in the mean time just know am a big fan... Keep doing it.. Your an inspiration all over the world
Thank you for the great content! The reality of military-based products is that they are usually of the highest quality and are built to last. I appreciate that you promote these for use instead of just collection.
Most US military equipment is built to only just meet the specifications which sometimes are marginal, unlike what is shown here which does seem very robust. What you can count on with most military surplus is that it saw proper maintenance in use and it worked properly when it was stored. Good storage isn't certain and some things decay with time so will need immediate replacement if they still function at all.
