Honda generators (EU2200, Eu2000 et al) have used and still do use rubber timing belts.. 17k to 35k hours running no worries. Ford car engine rubber belts...big problems. Ford should talk to Honda's rubber belt suppliers????
Yes, but in the 1960's Ford invented bio-degradable plastic. The plastic nut that held the gearstick in the gearbox would disintegrate leaving you waving the gearstick around in the air conducting musical cars. Everyone else used a steel screwed cap for the job so the gearstick stayed where it was originally intended. Ford has progressed to using rubber drive belts in the sump oil now - engine goes kaputt faster than a Russian tank in Ukraine.

4:00 Bird crap >does< etch clearcoat, but by no means does it etch through all the paint. I recently discovered a gigantic bird plop on my car that had been baking in the sun for 2 days and it did etch the paint such that chemicals could not take it off. I managed to remove it in less than 2 minutes with some car polish, a sander/polisher attachment for a cordless drill and a wool pad, and a microfiber cloth for a final hand buff to restore any remaining swirling. Only had the cordless drill spinning the pad for like 10 total sec (maybe 5 if it were a bigger pad). The key is ensuring the car is waxed a few times a year as that greatly slows down the etching process.
If the roof on my 20+ year old falcon can have bird poop for days and washed once every week or so, and be perfectly fine - youd expect no less from a new car.
Seems doubtful. The majority of new cars will mark quite quickly from bird poop, depending on the volume of the crap and temp, much worse if it is in a pile. It's far less noticeable on whites and light colours.
A difference here is that we're not talking bird poop. We're talking mammal poo. But you are correct. Contemporary paints should not have a step backwards in protective effects.

Mate that sonax is exactly what I am looking for- a non solvent spray that leaves an oil protection! Mr John, here is an idea …. do a segment on the incompetence of modern indicator lights at the front of newer cars. My experience is that, especially at roundabouts, most cars seem to have the laziest most ill defined indicator lights that are often lost within crazy plastic light fittings. Please don’t tell me that I am whinging! No, put it down!
Also at roundabouts most cars are signalling right and turning left because their incompetent drivers are expecting the car to know where they are going, and cannot trouble themselves to turn off the indicator. Just watch for 30 seconds at a roundabout and you will see several do this.

John, As a purveyor of relativistic realism I must correct you on your explanation of mass @speed of light. Not at 99.99%, but actually at the speed of light mass does not exist. Therefore, in the next 5-6 years extra large Hydron colliders will be deployed in medical field to treat obesity by eliminating mass. Furthermore, with the current increase in the number of large passenger jets fitted with electric turbofan engines and electric jet engines which use no fossil fuels, keeping passenger weight to a minimum has become paramount. That’s why in the next couple of years we will see hydron collides fitted into the boarding ramps at airports, making sure to minimize the weight of passengers (selectively or otherwise) to a level so low, that it is beyond what the human mind can comprehend.
I read Ed Macy's 'Apache' and 'Hellfire' books some years ago. I remember using a 'white phosphorus' 'Energa' grenade (I believe now banned) in the Australian Army.
You’re absolutely correct. When I’m traveling 15 to 20 times the speed of light, I noticed it takes for-freaking-ever to stop. I used to think it was because I’ve been using brake cleaner in my brake fluid reservoir., but now I know better. Thanks!
The way I look at this relativity stuff is that galaxy’s at the edge of our known universe are travelling away from us at close to the speed of light, so relative to them we are going away from them at the same rate. My mass has not changed ( except a bit since I retired)

With considerable real world experience with sailing skiffs & yachts (some race car stuff also) the use of Duralac corrosion inhibitor compound works wonders. This is especially crucial with stainless steel rivets holding stainless steel fittings onto aluminium spars such as masts, booms and spinnaker poles.

The other day I had a short time to get to the shop before it closed. I had to use my bike because of Rivnut in my car tyre. My strategy was to go at the speed of light, strongly requested by wife No2, however I got tired long before I got any where near to the speed of light. Just another factor to show you cannot cycle at the speed of light. I did weigh more on the way back as I got to the shop in time. Food for thought. Love the vid bye the way.
I was a heavy equipment fitter for years and found "Engineers" were great at talking theory and useless at actually fixing anything or talking practical reality.
As an electrician, with nearly 40yrs experience, I have never been handed a schematic from an electrical engineer, that I didn’t have to make drastic changes to, to get the desired result. All theory, no idea of reality. I only ever once ‘Wired, a control panel to ‘engineer specs’, under threat of loss of job, refused to power it up, then watched with the biggest shit eating grin, as said engineer applied power,causing the higher ups to quickly evacuate bowels when it exploded in their faces. Don’t agree with you on all engineers, apart from that, love your work.
@@TooOldToCare-kl3coI was an electronics engineer in a previous life. I had to advise the electrician wiring my house that he had managed to get the active and neutral reversed on a GPO. Incompetence doesn’t discriminate.
@AutoExpertJC I've never trained as an engineer or a fitter but have used many different tools over 45 years. I also know extremely clever people who have trained as an engineer with masters degrees. However I wouldn't trust them to change the brake blocks on my bicycle (insert rolling eyes emoji here).
Mr. Cadogan, as an auto expert, an engineer, and someone with a grasp on physics, could you enlighten me on something that I have wondered about for years? If you are in your car traveling at the speed of light, and then you turned on your headlights, what would happen? A bonus question; would it matter if your headlights were incandescent or LEDs (as incandescent bulbs are slower to reach optimal illumination)?
Ukraine has been using cluster munitions from the U.S. for quite some time now and not to any great effect unless you're civilian. Russia on the other hand is spinning up their manufacturing base to normal operating levels, churning out FAB-3000 glide kit equipped bombs.

Hi there JC. I'd like to see your take on concentric hub spacers and the benefits of left foot braking in an automatic equipped vehicle, I'll get the 🍿 popcorn ready !!

16:52 what a silly idea. If the material is thick enough to counter sink the flange of a rivnut aka nutsert then it’s thick enough to tap a thread into. If the material is too soft or weak to hold a thread then counter sinking it would be a stupid idea also. I’m not sure about galvanic corrosion on stainless steel into mild steel , unless it’s being used as a grounding point or it is exposed to a lot of water I don’t think the metals are sufficiently dissimilar to setup an electric current needed for corrosion to occur. Stainless steel is mostly just ordinary steel with some chromium and nickel mixed in. Even so it is always best practice to paint the bare metal or use thread locker or even superglue on the shell of the rivnut to seal out moisture.
I can back part of the Bat Shit story, when they crap on by brick fence, if i dont get to it before it "sets" [like concrete] I need a hammer and chisel to remove it, don't know what is in their digestive system but a bricklayer could sure use the wet stuff.
I am rather cranky about so many things in life. I often feel a sense of relief when someone else is even crankier than me about things, that puts things in perspective really. In a way holding back my own crankiness in stark contrast to those doing the click clack keyboard warrior typing thing it a kind of is sort of an inverse pissing contest typing this here comment. Combined with a sense of entertainment with a hint of a grin or a smile I rather enjoy viewing these videos. I wonder why this resonates as much as it does with my Dutch brain. Consider this a well meant mild compliment! Thank you.
Travelling at "C". You are at rest, everything else is going at "C". Everything you feel etc is exactly like you are at rest. How hard is it to turn the universe around to change direction?
The overly simplified version of why relativistic mass doesn't produce a gravitational field is because it's an artifact of the time dilation of the fast moving object, not it's actual mass. The slowdown of time for the fast moving object causes acceleration from applied force to be less than if time was running at the same speed as the stationary observer.
Interesting comment about the stainless nut certs in steel . I would really like to see those results I too have studied metallurgy managing to be accepted for a position at the NSWGR lab just before the site was closed down which precipitated the closure of the metals industry in NSW As you should know all corrosion is a galvanic reaction so any 2 different metal in contact with each other + something to complete the circuit creates a galvanic cell which leads to corrosion . Even different stress levels in the same metal will make a galvanic cell as will the boundaries between the pearlite & cementite phases in plain carbon steel. Unless the steel around the hole drilled to insert the riv-nut was normalized the edges of the hole will make a galvanic cell with the rest of the steel panel . These were fun experiments I gave to my students to do as it was easy to do a colourmetric proof of the cells forming the fun came when trying to actually measure the galvanic voltages between say an upset nail head , the indentations from the clamp when the head was upset and the rest of the wrought shank . I will not dispute that a galvanic cell will be produced but unless it was say on a boat trailer that regularly immerses in salt water I would doubt the significance of the galvanic actions between the stainless and the body steel. Even more so because different stress levels in the same piece of metal also create galvanic cells So for the afore mentioned rivet there is one between the flange and the body , There is another whole series of them between those indentations & the body and this will be before it is even set . Once set there will be multiple galvanic cells right along the newly formed flange , and a massive one where the metal folds back on itself then another series between the remainder of the body & the newly formed flange on both sides of the flange. Then as with everything protected by galvanizing the zinc is sacrificial so will be consumed by the Zn-Fe cell till eventually it is all gone and this is assuming that the galvanizing / plating does not crack & split during the setting process in which case it will be consumed even faster due to multiple cells being formed. . This is particularly relevant now days as the time interval between the vehicles crossing the driveway at the car dealers and the same vehicle crossing the driveway at the St Marys shredder ( should Sims still have it here ) gets exponentially shorter with each new model as we consume ourselves into extinction. I have never dropped nut cert into a dish of Agar but it would have been interesting to do an unused one against a set one then a set one of different metals into different metals to see just how aggressive the reactions were then of course some salt water accelerated corrosion samples , weighed to determine the actual loss of materials which I do not think would be significant unless you were say a manufacturer of new cars adverse to creating possible warranty claims no matter how remote the chances were .
John great channel and enjoy watching. These tungsten munitions have been used in artillery and tank rounds as well . The copper v or shaped material is also effective in explosive charges beehives bore hole charges . Depleted uranium munitions designed in the same manner were used in the first gulf war and thankfully not used when I served in Iraq in 2003 against. The Apache helicopters made short work of an Iraqi t72 , which I seen peppered with this ammunition.

John- not wanting to rain on the parade of your initial correspondent however you will find the following information enlightening for your audience: “Bat guano has a pH of 7.5, making it slightly alkaline. While it's not highly caustic, it can be corrosive to building materials, such as insulation or ceiling joists. Prolonged contact with accumulated bat guano can weaken these materials, causing them to break down over time” ie bat guano is not acidic at all- quite the opposite.
Mass doesn't change, but it feels like it does. Gets harder and harder to accelerate in any direction as you get closer to the speed of light. Eventually your energy to accelerate towards the speed of light any further results in more and more energy being required hence why "nothing can travel at the speed of light"
I'm sick and tired of RUclipsrs like you abusing the art of alliteration...it has got to STOP...( the bit in upper case is me shouting ). Thanks for your witty, often caustic, yet insightful posts 😂😂
As soon as you post a video, I go straight to the comments. Without even listening to your commentary I find the replies an entertaining read. You sure get the “wackos” out of their trees but they keep coming back! Maybe it’s like that portrait of Kramer when a guy says “He’s a loathsome offensive brute, yet I can’t look away”.

The other day I had a short time to get to the shop before it closed. I had to use my bike because of Rivnut in my car tyre.
My strategy was to go at the speed of light, strongly requested by wife No2, however I got tired long before I got any where near to the speed of light.
Just another factor to show you cannot cycle at the speed of light. I did weigh more on the way back as I got to the shop in time.
Food for thought.
Love the vid bye the way.
I was a heavy equipment fitter for years and found "Engineers" were great at talking theory and useless at actually fixing anything or talking practical reality.
I've met some shit fitters too. It depends on the individual. Engineers who never had their hands on the tools are terrible.
As an electrician, with nearly 40yrs experience, I have never been handed a schematic from an electrical engineer, that I didn’t have to make drastic changes to, to get the desired result. All theory, no idea of reality. I only ever once ‘Wired, a control panel to ‘engineer specs’, under threat of loss of job, refused to power it up, then watched with the biggest shit eating grin, as said engineer applied power,causing the higher ups to quickly evacuate bowels when it exploded in their faces. Don’t agree with you on all engineers, apart from that, love your work.
@@TooOldToCare-kl3coI was an electronics engineer in a previous life. I had to advise the electrician wiring my house that he had managed to get the active and neutral reversed on a GPO. Incompetence doesn’t discriminate.
@AutoExpertJC I've never trained as an engineer or a fitter but have used many different tools over 45 years. I also know extremely clever people who have trained as an engineer with masters degrees. However I wouldn't trust them to change the brake blocks on my bicycle (insert rolling eyes emoji here).
@@andyburnett8012Why would you ask them to? That’s not what they are trained for.
E=mc2 would have to be the most famous equation, yet some people don’t notice the m and the c are on the same side.
I'm here for the comments on the comments, on the comments.
Mr. Cadogan, as an auto expert, an engineer, and someone with a grasp on physics, could you enlighten me on something that I have wondered about for years? If you are in your car traveling at the speed of light, and then you turned on your headlights, what would happen? A bonus question; would it matter if your headlights were incandescent or LEDs (as incandescent bulbs are slower to reach optimal illumination)?
@9:44 "Bear Metal" would be a good name for a band.

_I'm still happy with my 2022 Auto-Expert Suzuki Ignis btw ;-)_
I just love how you say things, to wind people up and make them see red. Again brilliantly delivered
I do like a bit of "Bear Metal".
The therory bit at the end. Is that the same as that episode of the Flash when he belived that if he ran fast enough he would be indestructible. 🏃👍
Ukraine has been using cluster munitions from the U.S. for quite some time now and not to any great effect unless you're civilian. Russia on the other hand is spinning up their manufacturing base to normal operating levels, churning out FAB-3000 glide kit equipped bombs. The small pellets of the ATACMS don't quite stack up, particularly when most are shot down.
Hi there JC. I'd like to see your take on concentric hub spacers and the benefits of left foot braking in an automatic equipped vehicle, I'll get the 🍿 popcorn ready !!
I have often wondered when watching your videos what your go to lubricant is. Thanks for the clarification 🫶
I worked at a chemical factory that made car wash for quite some time. From our testing it showed if your car is kept clean then animal droppings take quite a while to make any difference all to any paint work.
Trump is already using that one.
@@Chrisamic What does that even mean?
Oh John , I'm a beard stroking big 4x4 owner who loves dingo piss creek camping. Now i don't think you have ever been there . But trust me when i say you can't get there in a Tesla. And doubt your Mitsubishi would get there . But i do live in hope that you will one day learn the joy of beard stroking. 😅😂❤. Love ya work mate .
He will never know what he is missing.
Love the five finger death punch tee worn in previous vids, they do a wicked Kenny cover...
OK *At It* 😉😉
Nah not removing the emojis because writing it twice isn't fun.
Love your analysis of the effect of tungsten darts on APC personnel.
Thank God the yanks also use much more humane uranium depleted rounds on tanks & similar armour.
(no emoji)
Yes, thank Elon for that.
John after watching the daily alphabet soup Ken and Barbie news i need some humor so i watch you and love your sarcasm! Keep up the good humor retired Auto Truck mechanic Steve in the US
16:52 what a silly idea.
If the material is thick enough to counter sink the flange of a rivnut aka nutsert then it’s thick enough to tap a thread into.
If the material is too soft or weak to hold a thread then counter sinking it would be a stupid idea also.
I’m not sure about galvanic corrosion on stainless steel into mild steel , unless it’s being used as a grounding point or it is exposed to a lot of water I don’t think the metals are sufficiently dissimilar to setup an electric current needed for corrosion to occur. Stainless steel is mostly just ordinary steel with some chromium and nickel mixed in.
Even so it is always best practice to paint the bare metal or use thread locker or even superglue on the shell of the rivnut to seal out moisture.
I can back part of the Bat Shit story, when they crap on by brick fence, if i dont get to it before it "sets" [like concrete] I need a hammer and chisel to remove it, don't know what is in their digestive system but a bricklayer could sure use the wet stuff.
I am rather cranky about so many things in life. I often feel a sense of relief when someone else is even crankier than me about things, that puts things in perspective really. In a way holding back my own crankiness in stark contrast to those doing the click clack keyboard warrior typing thing it a kind of is sort of an inverse pissing contest typing this here comment.
Combined with a sense of entertainment with a hint of a grin or a smile I rather enjoy viewing these videos. I wonder why this resonates as much as it does with my Dutch brain. Consider this a well meant mild compliment! Thank you.
Travelling at "C". You are at rest, everything else is going at "C". Everything you feel etc is exactly like you are at rest. How hard is it to turn the universe around to change direction?
The overly simplified version of why relativistic mass doesn't produce a gravitational field is because it's an artifact of the time dilation of the fast moving object, not it's actual mass. The slowdown of time for the fast moving object causes acceleration from applied force to be less than if time was running at the same speed as the stationary observer.
I would like to see more workshop vids.
Interesting comment about the stainless nut certs in steel .
I would really like to see those results
I too have studied metallurgy managing to be accepted for a position at the NSWGR lab just before the site was closed down which precipitated the closure of the metals industry in NSW
As you should know all corrosion is a galvanic reaction so any 2 different metal in contact with each other + something to complete the circuit creates a galvanic cell which leads to corrosion .
Even different stress levels in the same metal will make a galvanic cell as will the boundaries between the pearlite & cementite phases in plain carbon steel.
Unless the steel around the hole drilled to insert the riv-nut was normalized the edges of the hole will make a galvanic cell with the rest of the steel panel .
These were fun experiments I gave to my students to do as it was easy to do a colourmetric proof of the cells forming the fun came when trying to actually measure the galvanic voltages between say an upset nail head , the indentations from the clamp when the head was upset and the rest of the wrought shank .
I will not dispute that a galvanic cell will be produced but unless it was say on a boat trailer that regularly immerses in salt water I would doubt the significance of the galvanic actions between the stainless and the body steel.
Even more so because different stress levels in the same piece of metal also create galvanic cells
So for the afore mentioned rivet there is one between the flange and the body , There is another whole series of them between those indentations & the body and this will be before it is even set .
Once set there will be multiple galvanic cells right along the newly formed flange , and a massive one where the metal folds back on itself then another series between the remainder of the body & the newly formed flange on both sides of the flange.
Then as with everything protected by galvanizing the zinc is sacrificial so will be consumed by the Zn-Fe cell till eventually it is all gone and this is assuming that the galvanizing / plating does not crack & split during the setting process in which case it will be consumed even faster due to multiple cells being formed.
.
This is particularly relevant now days as the time interval between the vehicles crossing the driveway at the car dealers and the same vehicle crossing the driveway at the St Marys shredder ( should Sims still have it here ) gets exponentially shorter with each new model as we consume ourselves into extinction.
I have never dropped nut cert into a dish of Agar but it would have been interesting to do an unused one against a set one then a set one of different metals into different metals to see just how aggressive the reactions were then of course some salt water accelerated corrosion samples , weighed to determine the actual loss of materials which I do not think would be significant unless you were say a manufacturer of new cars adverse to creating possible warranty claims no matter how remote the chances were .
John great channel and enjoy watching. These tungsten munitions have been used in artillery and tank rounds as well . The copper v or shaped material is also effective in explosive charges beehives bore hole charges . Depleted uranium munitions designed in the same manner were used in the first gulf war and thankfully not used when I served in Iraq in 2003 against. The Apache helicopters made short work of an Iraqi t72 , which I seen peppered with this ammunition.
Statistics suggest that only 51% of people make what could ordinarily be considered to be normal comments.
Then there's the rest of us...
🤠🍻👍🏻 Vroom Vroom!. 🚜
51%? Why not 52% or 49.5%?
@@phprofYT Because. So there.
51% sounds incredibly generous.
86.7% of people make up their own statistics.

Prime Mincer,
I was 49 seconds in and I just knew the rest of my evening was going a whole lot richer for watching. Looking forward to the end. Thank you
Funny as hell John, sore sides from laughing.
Cheers, Greg, Queenstown NZ. 🙂
I subscribed a few videos ago John, so that muppet that left has already been replaced, and on that Welding video, I have no idea how them few fellas harped on about brake fluid, when I thought you were ultra clear on the warning for brake “cleaner” and not brake fluid 😂😂 must be all that bear metal going to their feeble minds and painted on ears 😂😂😂 love your work, not all us Qlders share the same genes haha
Grizzly "bear" metal....or "brown" bear metal?
It’s like watching the muppet show!😂
John- not wanting to rain on the parade of your initial correspondent however you will find the following information enlightening for your audience: “Bat guano has a pH of 7.5, making it slightly alkaline. While it's not highly caustic, it can be corrosive to building materials, such as insulation or ceiling joists. Prolonged contact with accumulated bat guano can weaken these materials, causing them to break down over time” ie bat guano is not acidic at all- quite the opposite.
put a standard size spare in the boat trailer that also has same stud pattern as the tow car.
I bearly understood any of the speed of light stuff.
Mass doesn't change, but it feels like it does. Gets harder and harder to accelerate in any direction as you get closer to the speed of light. Eventually your energy to accelerate towards the speed of light any further results in more and more energy being required hence why "nothing can travel at the speed of light"
Yes, one can get countersunk riv-nuts for flush fitting applications.
What I’d really like to see is your objective assessment of the implementation of nuclear power generation in Aus.
hear, hear. bring it on!
Yes, that would be interesting.
I'm sitting on the fence ATM.
Help needed.
I'm sick and tired of RUclipsrs like you abusing the art of alliteration...it has got to STOP...( the bit in upper case is me shouting ).
Thanks for your witty, often caustic, yet insightful posts 😂😂
MY PLEASURE!
Nothing better than dry humor from a fellow old white guy, I always say.
John you could paint us some pictures of a rusty ranger
Use crayons for us plebs
i don't know what's more painful, listening to JC going on about these crap comments or top gear australia!
As soon as you post a video, I go straight to the comments. Without even listening to your commentary I find the replies an entertaining read. You sure get the “wackos” out of their trees but they keep coming back! Maybe it’s like that portrait of Kramer when a guy says “He’s a loathsome offensive brute, yet I can’t look away”.
Take that cap off ya big C 😂
Have at it?! Why, them's fighting words. (Which I'll respectfully decline to act upon.)
You are just a classic John, always have been mate, so proud of you and some of these segments that you bring up, as you just crack me up 😂😂😂
I disagree with everything that you have said in your video. Wait, strike that, reverse it.😂
The best episodes ever these ones John
Mass never changes with speed but when you hit an immovable object
The faster you are going the bigger the splat
Maybe that is what is confusing them
When I use rivnuts I always tighten the bolt into it first to make sure it is completely crushed in place
CHEERS from AUSTRALIA
Brilliant video once again John. Interesting, informative and highly entertaining. More reaction videos required I think. Top man, thanks from Adrian.
You could have told them where the infinite part can be applied. It helps me to go to sleep at night thinking about why that is.
The rivnut episode was one of the best, Def not for them light hearted nutserts!
LOL, I don't have a problem with your content, it is very educational, please keep up the good work.
Those tungsten darts are nasty and as a former AFV Crew Commander I had nightmares about them.
A Big man can admit when he gets it wrong😢😅😂
