- We hired real mechanics and asked them to break down good & bad car advice from Tiktok.
Huge thanks to our experts!! Sandro, Daniel & Angelina for sharing their expertise with us (and you!)
Real Mechanic Stuff is a brand new channel from your pals at Donut. We'll be featuring all kinds of automotive experts every week.

everyone: "that's incredibly dangerous never do that"
sandro: "i did this monday actually"
im an electrician with lots of these batteries. i have actually done this on more than one occasion in my 26 years doing electrical. the conductor size is important with this. if you use a conductor too small it will melt. other than that and potentially high nominal voltage from the battery it works well. has gotten me out of being stranded situations
Shut up emet
"potentially" high nominal voltage 😁
Classic sandro

Dropping a magnet into the finger tip of a latex glove is definitely a big brain move. Plus you can still get an MRI in the future if you don't get a magnet surgically implanted into your hand lol
Not gonna lie, I'm def. using that trick next project
Used to work in the hospital & this was my 1st thought. Love the effect, just hope he'll never need an MRI lol
“He has no friends”. Best line yet! 😂😂😂
Daniel straight up made Nolan uncomfortable 😂 “can I have a smell”
That’s a mechanic right there 😂
As an airplane mechanic, can confirm.
James would have said "have at it bro!"
Nolan is the most handsome boy

I love how Sandro called them “zippy-ties”
He's called them that in other videos on this channel. He's consistent.
The brake disc thing is legit. He's not drilling new holes or enlargening existing ones, he's running a drill through the hole to clear out the carbon deposits - helps restore some cooling efficiency. I've been doing this to motorcycle brakes for about 15 years as part of my pre-summer service for my bikes, and on my cars whenever I've installed new pads.
I think he was just cleaning the brake dust build up in the holes.
it's obviously not dangerous, and not waste of time either.
it's not really necessary to do either, for normal driving situations.
I like the three mechanics you have on this video. I hope you keep these 3. They all seem like they are very different from each other, but all really knowledgeable.
Sandro needs his own series.
Yeah, judging by those teeth, he's been doing this for 700 years.
Yo his tats, his reacts and his TEETH, this man has lived a life
@@KalijahAnderson don’t hate on my Nigga sandro he’s goated
@@chrislangstaff I wasn't hating on him, I was making a joke, and implying he's been doing these things for centuries because he's a vampire.
No hate there.
@@KalijahAnderson No No, I agree 100%! I think they're cool. All love brother.
Sandro is cool af, so chill, so dry, so funny
ye agreed!
we gobba ignore the vampire teeth?
I'm mad about magnet finger. I have some little magnets like that, and vinyl gloves. And I recently bought one of those long, bendy magnet on a stick things to retrieve a socket from an engine.
I'mma tell my kids this is blink 182
No offense but damn you're old ur kid wouldn't even know who blink 182 is lol but good luck
@@nemobueno7934You know that's the point of the "tell my kids this is _____ " joke, right? That kids would not know who the subject is, were you born on a staircase?
@@ELTABULLO using blink 182 as your subject for the joke just really drives home the point you're old brother
@@nemobueno7934 That's also the point, were you raised by a teen mom? You're not supposed to have multiple kids being young, I also sense she's single but that's not related to the joke

As a window tinter, the “tint hack” absolutely doesn’t work. 😂
I know I’m late to the party, but I agree 100%! Been in the industry coming up on 18 years and there’s absolutely no way the tint “hack” worked. I’ve worked on plenty of those trucks and there’s a million issues with that video. I’d like to see that “hacked” tint job the next day and the horrendous curing. Lol. That video depends on people not knowing anything about window tinting to be impressed.
Lining up that tint layer seems impossible.
@@aznp33nRocket a tinter I watch on UA-cam named Matt shows how it’s done basically. That’s why they only show the rolling up and down part. Not the actual set up.
@@carstenhilbert5472Thats what I thought.
This one didn't even work that well, as there is a white streak on the bottom half of the window.
In the 70's and older guys who did body repairs like the one with packing tape were call paper hangers Instead of packing tape they would pack the whole with wet newspaper of metal door screen. Once the hole was backed up, they would use either papier-mâché or wet paper strips sometimes coated in wallpaper paste and then let it dry so it was firm. They then applied bondo and sanded it out for paint. These repairs would normally last until the first rainstorm when the paper got wet and the water would come through from the back and bubble the paint.
Another thing that was done was used on cars with rusted out rocker panels. The rocker was trimmed back so only the sill and inner rocker remained. The lower sill trim was removed and then they used drywall screws and attached a piece of 4 x 4 lumber in place. The 4 x 4 was ground to shape with an angle grinder with sanding disc's and then it was covered with bondo and painted. The sill trim covered up the top screw heads and the back of the rocker panel concealed the screws unless you got under the car. This repair could last for years before it was discovered.
About the first hack with the cordless power tool battery - keep in mind cars use 12V batteries, while power tool batteries range range from 3 to 48V. Also, in general, car batteries are rated for much higher power draw (amperage) than cordless power tool batteries. If you have a significant mismatch between your car battery and your power tool battery, you do increase various risks. When it comes to things not working out while attempting this hack, best case is your tool's battery is too low voltage and the car still won't start. On the other end of the "this didn't go as planned" spectrum, you have:
* Car's battery "explodes" ie sprays acid on you, which is pretty terrible for your skin and if it gets in your eyes you'll most likely lose your vision permanently. The risk of that depends on various things, like the type of battery and whether it has Pressure Release Valve (if applicable), and whether it has any defects.
* The power tool's battery gets damaged from being overstrained, which can mean a fire at worst and it not holding much/any charge anymore at best.
* Bonus risk - the conductors between the two batteries are too thin and melt/catch fire/burn you (depending on what they are made of).
Batteries are pretty scarry when they go catastrophically wrong, I presume you've seen how much damage can be done even by a small 3.7V battery like the ones in the Galaxy Note 7... Or the 18650 batteries commonly used in e-cigs, plenty of videos online. Power tool and car batteries pack a lot more punch than a smartphone battery. If you'll be doing hacks with them in a pinch, I recommend you know exactly what you are doing and take some measures to protect yourself just in case... you never know when you'll draw the short straw.
Drill batteries typically use 14.4, 18, and 20 volts. A weak 14.4 might work, but then it couldn't put out enough current to do the job.
Also the fundamental problem if you can even access the positive and negative terminals with spoons that way is a bigger problem.
That vid was 90% fake.
@@ezg8448 I think you could hit a 12v battery with 14.4 for a little bit without messing it up.
The biggest problem is that even the supersize tool batteries are like 9 amp hours. They wouldn't do a thing to help a car battery.
The car in the video was about to start before they tried the "hack"
As a warehouse worker, that forklift one was scary af
Deadly
it works if you're ready to run as soon as you hear anything
@@aclonymous No job is worth your life.
@@aclonymous Bruh....thats some sketchy sh*t.. 😂
Right? I used to have my forklift licence, and that was a huge NOPE NOPE NOPE the moment I saw it. Tines up high with an unsecured unbalanced load way forward of the backrest, mast tilted forward, no one in the seat, people working just underneath the load, ... I've seen some sketchy shit with forklifts, I know the difference between regulations and reality, but this is scarier than anything I've personally seen.
And I mean, they were probably fine. That's how forklifts are - everything's fine until suddenly it's not fine anymore, and at that point there's absolutely nothing you can do except (hopefully) get out of the way.
Sandro is naturally funny and endearing, get this guy a show
yeah dude look like he belongs in the sons of anarchy gang the mayans xD he would have been perfect cast
Ive totally used the engine turning over to loosen bolts. It works best on crank pulley, but if you have a nice belt it can sometimes work elsewhere. I suggest you pull a fuse though so you don't start the engine, just turn it over.
LOL, it works, but did anyone else notice that the center of the ratchet spun indicating it wasn't holding anything....otherwise they said they did this but didn't actually do it for the video. They held it easily because they weren't actually holding against pressure and instead the ratchet just spun....
My only comment is that I love how Sandro respects the sketchy stuff and admits to doing it.
Sandro is my favorite Donut reoccurring guest by far. Absolutely hilarious and well versed in his craft. I would love to work in his shop.
Bro I don’t comment at all but I need to figure out why I love Sandro so much. Like I actively wanna see more videos of him in his element
@@nes4592Because he's the man.
Jeremiah and Sandro could have their own series. So funny.
We need “for the boys” shirts. Like with a wrecked car on it.
Hell yeah! I’ll buy 2 of them one in white and one in yellow.
Facts
The energy the both of them bring is great!
I second this. With a cool sunglasses emoji on the back LMFAO
Ryan Long already has those for you.
The timing of this video couldn’t have been better! I was just looking at jack stands and had only found your older 3 ton one. Thank you for the update!!!
I have been watching this channel non stop since I found it a couple days ago. Subscribed! Awesome content you guys!
Sandro is still my favorite mechanic. Dude keeps it real.
The magnet fingers hack was my favorite of the bunch. Not only good for retrieving stuff, I bet it works for starting that one SOB of a bolt you can barely reach, and have to drop a dozen times before you get it started.
Didn't even think about that! 🤯
@@maybeweneedmore That's why it is a "hack" :D
dont eve try that on german cars. )) they use aluminium bolts))
@@robant5578 Well, no. Just in very few areas. A
This Im going to use
I have used scouring powder like Comet on belts to quiet them up temporarily and to verify that the belt is actually the noise. Also I have a couple extensions that are like very thick speedo cables and those work well like the hot glue sticks but you can actually but a fair bit of torque on them. They are very old at this point and I haven't seen them sold for a long time.
Love how Zach has a mechanic with him like he’s not one himself
Jobe must have one hell of a time at airports
I have a metal plate & screws in my arm. Never set off a metal detector until after 9/11 (when I assume they cranked up the sensitivity). Interesting thing is that I stopped setting them off just a few months ago 🤷🏽
@@knighttimestorieslv my grandma has a metal knee. It's always been fairly 50/50 for setting them off
i wonder how does he play the guitar properly, that magnet would be affecting all of the strings he picked.
As a former Master Tech, that magnetic finger thing was hilariously legit.
When I heard that my first thought was just taping a magnet to your finger but that glove trick is pretty nice.
OK, this video saved my butt tonight! Driving home in the dark and my Alternator crapped out, ended up off the highway in the pitch dark. I left my booster pack at home, but had my DeWalt 20v tools in the trunk.... I boosted the car 6 times to get to a hotel, with my DeWalt work light bungee corded to the front of the car as a headlight. I remembered seeing the 20V battery trick from this....do not use small gauge wire... it can't handle the Amps... I did it anyway!
Zach casually mentions a magnet implant and we don't talk about it?!
everybody wondering what happens if he needs an MRI
Asking the real questions
@xxmeanyheadxx if he was in a life threatening situation they'd cut it out.
@@db336 and if he spilled his bike and wasnt really able to communicate clearly they would throw him in the mri machine and remove it without cutting lmao
@@xxmeanyheadxx you underestimate how hospitals work. They would pull prior surgery records off his license or off his name address dob etc. from whoever called the ambu or brought him in. In any case. That implant is borderline surface level. Worst comes to worst it's just a little bullet hole when it's yanked out.
Hold up, did we just gloss over the fact Jobe has a magnet implant
That blew my mind
Apparently so.
Fr I looked into getting one done and its kinda sketch.
Right!? How the hell has there not been a stand alone episode about that?
@@joekent6576 Shoot them an email and see if they’ll put it in the next season of money pit. I bet they’d do it.
Electrician here. I have a magnetic dermal implant in my left ring fingertip. I dont drop screws anymore, and I can tell if there is AC current on a conductor. It kind of works like a load detector. The little magnet will vibrate in my fingertip at 60hz if im close to a conductor that has enough load on it. Blew my coworkers' minds when I got it.
For the tire bead breaker, I've got the more expensive end to that. I occasionally drive a truck with a liftgate with a load full of mounted semi wheels. In a pinch, I've put 6 mounted on the lift gate, and lowered it into a tire I needed to change out. Ever since then I've made sure to have a wedge with me.
We rednecks do this with old school bumper Jack's. I remember my dad breaking down hundreds of tires when I was a kid.
As a long-time technician, one of my favorite diag tools for a squeaky belt is a bar of soap! Works just like the deodorant. If the squeak stops, you need a belt. If it doesn't, pull the belt and check your pulleys. Plus, the look on a customers face when you walk out and fix their car with a bar of soap is always worth the cost of bar soap!!
One generation of Renault gas engines had a badly engineered pulley system, and any belt would start squeeking in maybe a week or so in low RPMs. You could pay someone to fix the pulleys, REV loudly every morning to warm them up, change the belt every week ... or (what I did) just lube it up!
Those tire marking crayons are also a great alternative
I use wax candles. 👌🏻
The forklift one is hilarious because every time I go to a junkyard I see two guys under a car held up by a forklift 😂
If you have two of them and each has an operator to raise at even speeds then you can make it pretty similar to a 2 arm lift tbh
Edit: But a single forklift is sketch as hell, and 2 still isn't ideal, but not nearly as sketch
Something similar to this is how they used to do car repairs in the 1910s - 1920s, apparently? I've seen a photo like that, but the old Buick was held to a steel beam near the ceiling with a come-along, if I'm not mistaken. Just do a web search for "1920s car repair" under images, and you'll probably find the pic easily enough.
Never ever trust hydraulics, if they fail you are done
I've made my own air hammer attachments before, the work great. You never know when you'll need one. A great example is take a air chisel bit, cut it flat then grind a groove into it. Got a hard to reach bolt you can't break loose? Throw a wrench on it, then put the groove in the air hammer over the wrench and send it. I've also welded custom air hammer tools, wear safety glasses if you try it. You'll find out really quick if your welds have good penetration or not lol.
Also, the tire hack, easier way is to lay a board like a 2x10 or even a 4x4 that's a few feet long on the edge of the tire and drive another vehicle up the board
Love what y'all are doing here! Hilarious! Keep em' comin
Sandro with Jeremiah is THE BEST combo for this show lol
When I was in trade school, as part of our welding unit, we had to make a simple brake caliper tool. One that I still have in my toolbox & still use 20 years later. Homemade tools WORK.
Sandro haha. Soon as he said B16 swaps I remembered the B16 swap in my buddy's 91 CRX haha.
I also remember my other friend's 90 240sx coupe auto to manual conversion, the pilot bearing was stuck AF, we heated it up and then gave it a few good slide hammer whacks and it came right off.
3:18 I remember my dad doing that on one of his Mazda trucks. Though he still had everything hooked up still, so the truck actually did start while trying it. He was know for those kinds of oversights.
Sandro, is the man, my spirit mechanic brother. Angelina, the woman I wish had been around 20 something years ago and met in shop class. Daniel, the guy I have worked with in too many jobs and like me is getting more cynical with age. Good crew here.
Nah bro, I bet Sandro was cute when he was young lol
@@cenciende9401 gay 😂
Aw cute
These guests are so good. And they’re also perfectly paired with each member when it comes to personality and vibe. At least imo.
I'm a sahm and this got in my recommendations. Thanks I really enjoyed it even though I don't know anything about cars.
I'm taking my vehicle to Sandro, 100%.
You know he will get the job done, no matter what. And he won't charge you for some 1-time use specialty tool.
Sandro is my all time favourite mechanic in this series. Dude knows his stuff for sure!
The Breakrotor drilling isn't to enlarge the holes, its for cleaning them up. The breakdust clogs them up over time. And if you look at the rotor it was pretty old and well used
That’s what I was thinking.. idk why they say he was boring it or was drilling it… that was obviously brake dust
No, those holes are absolutely not OE on that rotor. They're all the fuck over that rotor, not even measured out well or anything 😂
@@michaelmeissner7545 he was cleaning them out. Not drilling them
@@michaelmeissner7545 i did not claim that they were OEM or anything. Just that they were cleaning the holes
@@derLeomitmBenzer OEM...what he means is the rotor's are Out of Ballance by some idiot randomly drilling holes ... perfectly balanced part means warping and Soon to be destroyed Bearings...
Non low profile tires I break beads with a medic pick axe. There’s a tool in the trucking industry for it but I don’t have one so I have changed medium and a few lowish profile tires like that. Method: swing that thing at the bead and work your way around. Sometimes the wheel will bounce half way out of the tire if you put enough rage into the swing. I suggest practicing by chopping wood first though. Accuracy is key. My friend once used a circular saw as well when the pick didn’t work. The saw couldn’t get the metal ring of the bead though. We even put a 2x12 board on the sidewall and drive another car up the board and it wouldn’t come loose. His dad managed to do it in 3 swings of the pick after he came in from the bar half crocked. The tire had been through a lot of violence as the steering rack was so worn out it would allow one wheel to turn several degrees before the other side caught up. He couldn’t take the car over 35mph because of the steering wheel oscillation. He couldn’t hold on to it past 35 and the car was a bit jumpy. Lol
I love how Wildcat's "I know what wrong with it, ain't got no gas in it" in so many of these clips
As a long time Donut fan, LoCar team for life, and also a woman, I love this new channel. Angilena is my new role model
A friend of mine was, as far as I know, the first man in human history (first of 15 billion people or so) to start a dead battery in his car by turning another car battery upside down on it. It worked and he didn't die but when he told the story the day after at work (we are welders and mechanics) we laughed hysterically at his incredibly innovative but stupid action. Lovable guy though, he continues to be the Master of Random.
I consider myself "somewhat smart" and I probably wouldn't have thought of that. I'd try it in a pinch.

Fun fact: Earth's population reached 8 billion in 2022.
@@Jeff.78 - I was guessing at the number of total humans that do and have existed, maybe it's a higher number, I didn't google it because we don't know how many people live in China and India, both countries only keep a list of about a quarter of their residents, if that.
I did that before with an AGM, just set it on top, upside down, then cramked it over.

My electronics repair screw driver kit has a tightly wound metal spring that's the same idea as the glue stick. It actually worked surprisingly well for the application. You could feel the give in higher torque situations, but it would still tighten things pretty well.
Back in the day, when slotted and drilled rotors first came out, you could order a kit from the back pages of car craft magazine that had a template and bit set so you could drill and slot your own rotors at home

7:40 Back in the 80s I worked for an equipment hire company. Our forklift had a towball mounted on one tine so we could move trailered equipment around the yard. We also used it as a crane to load trucks with large sandblaster pots, big 400-amp diesel-powered welders, and other stuff. But we NEVER stood under a load, and we never had an incident, and most of the yard was packed gravel.
This is one of the best shows I've seen on UA-cam...!
I loved the magnet finger and tire bead breaker! totally awesome hacks!!
FYI. Cross drilled rotors aren't drilled for cooling, it's to prevent gas buildup between the pad and rotor. Pad gassing under heavy braking creates a feel very similar to run-out or surface irregularities, but dissipates as soon as the brake cool.
The whole thing with the bondo on the bumper is similar to how my dad would fix it but not quite there. He would take off the bumper. Pop rivet a metal backer on and drill holes through both. He would then cover it and the area that he ground around it with duraglass. We would then treat it like any other damaged area. The holes were so the duraglass would push through and have a better hold mechanically. We have done this thousands of times and never had an issue with it. Bumpers were always a pain to deal with though. We live in a small community and had repeat customers so you can't just treat them how big shops do. I've seen big shops turn out work that caused quite a few to never go back.
Metal backer being the key difference, a bit more support than clear packing tape, which will immediately release all the Bondo with the slightest thumbprint.
One of the less obvious dangerous things was seat-belt car pushing guy. You've looped a belt over your head and attached it to a multi thousand pound rolling object with no quick release anywhere near where you can reach it. If you suddenly hit an incline, a bump or otherwise lose control of the vehicle you're getting dragged or strangled.
as a tow truck operator, I’ve tried the seatbelt car pushing hack, makes it harder, easiest way to push a vehicle is my turning the wheels with your hands
That guy with the long hair seems to know his stuff, you should keep him around
Can’t believe none of the guys on the show figured out cleaning the holes in the disc, I’ve done this they collect lots of brake dust, rust and shit after a few years and this is a very good way to clean them
Yep seems like they have no imagination
I almost never laugh at these videos, maybe a chuckle... But the "Floppy Phillips" got me bro!
I did the jump start with the 18v dewalt a lot. Positive is the front terminal on the battery pack and a power cord plug fits perfect to touch the battery contacts .
The 20v seems like too much voltage for new cars sensitive electronics, but ive one it once. I use the 18v adapter so i can still use my cut extenion cord
love that you are giving this format it's own channel! Love the guys you hired! Keep up the good work!
yeah i normally dont like many reaction videos but this format is exactly the right kind of reaction video. it's adding to the content and being informative and helpful and entertaining
Thought he was gonna do the *slap the battery terminals with a wrench* trick to see if it sparks. Timeless classic
Crank bolt hack..
Done that with my old Volvo 945 when changing the tidning belt.
Works really good
I’ve used the drill battery one a couple times. If you look at your drill battery (dewalt) it shows which pin is positive and negative
Oh, I love this! Everybody is great, but Sandro might be my favorite. He seems like the coolest relative you could possibly have.
The battery jump start has saved me a couple of times, and the bendy bit has saved me some time unwinding a bolt I've loosened lol
2. There are so many good release knots. Use the string method to compress the spring. Then use a Highwayman's hitch or a halter hitch to fix it then you take the loose end of your rope and pull gently this will release the knot Wich ist really tight until you do this. Good side effect you won't loose a the rope or your fingers
The fork lift one..... once saw a guy doing this in a scrappers with a flat bed. He was then angle grinding the drive shaft off above his head....
Let's take a moment to applaud the fact that he was pushing that car in open toe slippers btw. Fackin legendary
I wanna hear the story on Jobe's hand now!!
The 1st hack, actually works. Only as a last resort, I’ve done it, roadside wasn’t answering it was single digits outside. Used my drill battery to jumpstart the car to get home
I just used a scissor jack and a short block of 2x4 to break the bead on all four tires yesterday. I got a new beater car and I had to replace all four TPMS sensors. Worked like a dream.
This channel is a great idea, these mechanic react videos on the main channel have been awesome, I'm super down for a dedicated channel for that kinda thinf
Sandro and Jeremiah is such a good combo, they could make their own channel
I too have used zippy ties. Love the content Donut! 🤣
14:47 years ago (mid 90s) a big Vauxhall (UK, Opel/GM) tuner was Courtney. Their grooved brake rotors for the Cavalier GSI/Turbo and Calibra where the things to have. I did some temp work at "Pace Products" where they would take OEM GM rotors and on a mill, I would run a CNC programme to groove them. That simple. But the cutting was done VERY carefully. A drill in a Dewalt it most certainly was not!
My High School Auto Shop teacher showed us magnet finger in 1980! Why he taught HS Auto is beyond me. He was certified by all US manufacturers. Why you can't always reach with a magnet on a stick but CAN with a fingertip still amazes me.
If I need magnet to get to something I'd put it on the end of a steel rod ( 1/8" or 1/4" extension ) not inside my glove which only give me a 2 1/2" more reach and I get my hand stuck in there.
leverage as well as intuitivity, it's easier and more accurate to pinpoint something with your finger than a massively extended rod
not to mention your finger can turn by the joints while a stick doesn't (not as easily nor around corners) intuitively so you can reach some pesky angles with your fingers
So the drill battery thing.... Well I have done it. It definitely works. DeWalt batteries have a cell balance connector built in like an RC car. The outer slots are the voltage on most drill batteries but the inner slots on a DeWalt are actually 2 connectors stacked and you should never stick anything in these or you will dead short a cell and burn up the wiring. One of these pins is also a temperature pin. On other brands you will usually have the full voltage and a sensor pin. It may be temperature or it may be some proprietary signal that simply tells the drill or the charger or the battery safety board that everything is okay or how and why it's not. Be careful with 18-20v batteries to only make contact while cranking because you may over volt the cars many computers otherwise. You can use 11.1-12v batteries safely but may not get all of the cranking power. The round cells aren't really rated for the required current but they will provide it. The flat foil cells are rated for more current but most drills don't use them.
As for the crank bolt, do not do this on a Mazda! Perhaps the Miata is different but many fords and Mazdas with 4cylinder engines don't have a key on the crank pulley and the engine has to be timed with a toolkit the locks the crank and a camshaft while you take the slack out of the belt. This way of pulley installation is being used more and more but ford/Mazda was the first I knew of and you seriously risk losing time and bending the valves. But if the car is old or you have experience with the way that model is timed then this is an old school trick which I have used to do an emergency fix in a tercel on the side of the road. It may help if you don't have the right tools or if you can't get the car high enough for a long breaker bar or don't have an extra set of hands to hold the crank pulley from turning.
In the air force, there is a binder that metals tech keeps for all local man (locally manufactured tools) that we make for us or other shops.
Now the rotors with the holes through them arent for cooling air. Thats what the vented center is for. Those holes are to allow gases to escape that the brake pads create when they are in use.
If the belt is squeaking, it's because it is slipping. Adding anything to the belt will only make it slip more, and when a belly slips, it does not spin the water pump as fast and will cause the engine to overheat. The belt may just be loose or it might have a bad bearing or tensioner that binds and makes it slip.
The drive-belt hack is interesting.
My aircraft uses a belt to spin up the rotors. In flight, the belt is loose, but to pre-rotate, tension is put on the belt and this is done when the engine is running. This causes a lot of squealing and vibration whilst the belt acts as a clutch.
We use various things to minimise the squealing (and allow for a little slip until things synch-up).
Some people use talcum powder. A lot of people (myself included) use "bumper-shine".
I'm so glad you guys started a channel for this. I've been enjoying this series and have always wanted to see you guys do more.
Not a car guy - but have used stuff like this in other places:
Ok - the plastic fender/tape thing. Take off the bumper, remove or "move back in place" the lose/bend material, clean it up, put on the tape ON THE INSIDE - put the "filler mass" on from the outside. shape it into place but make it a tiny bit thicker than you want it. Let it dry completely. now use sandpaper to grind it down to shape. paint it. done. That will hold unless someone kicks it or stands on it - especially if the filler mass you use is epoxy.
I used to work for a aftermarket install shop and whenever I had an LED under glow or rock light install I’d always turn off the shop lights and one of my snap on batteries to see how happy I am with the location of the lights and so how much they show and reflect off the ground
I work at a shop as a GS under a Tech learning and some of these scare me but..
Bro that spring compression held by string scared me the most! My tech told me the compression is enough to take your head off lol
The auto mechanics/auto body class I did in high school, our shop had a pretty sketchy patch done to the roof from a kid trying to tension a spring, but he didn't do something correctly and it shot the spring through the ceiling. It was like a 15' metal ceiling, so that was used as an example of what not to do for the next 8 years, before they moved into a new building.
Can’t believe you managed to get the mechanic lady from home in 60 seconds. Solid work chaps.
14:45 Drilling brake pad dust out of holes. Fast, easy as safe. They can clog up in half of brake pad, especially on the inside where most of the time you don't have access.
Holes are mainly to vent gases produced under hard braking, so fading is limited. The same job as slots on slotted discs.
8:56 taking "riding clean" to a new level
I think with the air hammer one you could also weld an impact socket extension on and you could use different sized impact sockets for different sized bushings. And if you need the end to be flatter than the edge of the socket face, just put a grade 8 flange nut in the socket.
I just put the socket on backwards. The edges are usually much more square and you get way more surface area.
@@willm1574 That makes sense👍🏼

That's how I press in and out bearings in the press.
2:48 my dad got incredibly lucky doing that. He was changing the rear shock on his Goldwing and didn't realize how much pressure a spring is under. He figured he could just unbolt it and put the new one in. Once the bolt came off he said all he heard was the woosh sound of it fly past his ear, and then the front window shatter and the spring broke our jacket closet door. If that spring flew 2 inches to the right there's a chance he'd either be dead or not at all the same person anymore. Ever since then, he listens to my mechanical advice.

Shock springs are no joke. Will literally kill people
the actaul use of drilled and slotted brake rotors is to clean off any excess of brake dust or debrey off the pads, the fans around the rotors edge are whats used to cool your brakes.
my son's dad did that drill battery thing to start his truck. He was in the middle of no where late at night. He wasn't sure that it would work, but his theory was that the voltage of the drill battery had more voltage then the truck battery, so it should be enough power to start the truck. He had a friend with him that was iffy about it, but it worked. He didn't do it with spoons though. It never crossed my mind to ask if the drill battery was good after that. I'm thinking it was, but he has many of those batteries since he has a lot of things that use the same kind of battery.
In regards to the crank bolt trick. Not all engines spin clockwise (in particular Honda).
