JB weld does need advertising :/. I guess the manufacturers figure jb weld is so good, they don't need advertising for jb weld. Either that, or the manufacturer doesn't want to bother with advertising. Either way, I agree that they could use they if they wanted through project farms permission.
Wow - I never would have believed it. Thanks for the video! Suggestions: 1. Show us the inside of the cylinder head after a minute 2. Run it until it fails 3. Fix the failed JB Weld cylinder head with JB Weld, and repeat!
Brothers Ford f150 intake manifold coolant passage cracked on a road trip, fixed it with JB weld and it made the 400mile journey back home and even did some errands around town before it broke again. Jbweld can fix anything, even a ford
You can get away with adding metal powder up to 1/3 of the volume of the epoxy. That both makes it stronger and better at dissipating heat. Cast it so i has fins like the original cylinder head, but taller to account for the worse material, and i think that thing would probably mow your lawn before it dies.
Anders Juel Jensen I’m not sure what the recipe is but I think JB weld probably already contains metal powder, either iron or aluminium. Or both. It’s good stuff.
I'm watching and realising you hadn't thought to earth the plug and I was surprised when it fired up but could see it arcing to one of the head bolt washers.
Haha somethings just work out, he might have been scratching his head for a minute trying to figure out why it didn't work if he didn't have to add the extra washer.
I discovered this channel about a week ago and can't get enough of your videos. It's amazing what you're able to do - entertaining and informative at the same time, with no BS. Keep it up, good sir!
Actually surprised it ran at all. Not because of the jb weld, but because there was no ground for the spark plug. It just so happened that the gap between the plug washer and the head bolt washer was close enough for the spark to jump, can see it arcing while its running.
FireAndGasoline, Yes, I placed the washers very close together, but not touching. For the conspiracy theorists, this provides proof that I'm using a non-conducting product. Thanks for watching the video and commenting!
FireAndGasoline good eye call on the washer arcing. I would bet money that was luck on his part. He probably didn't think about the plug being grounded. Never mentioned it.
The ground path for the plug was probably my biggest question. This is awesome! Also I was hoping you would test it to failure or at least disassemble the engine to see if combustion was chipping away at the epoxy.
iawindowss Too hard to see under all the annoying links...plus, idk enough about such things to be able to identify what's damage & what isn't, I'd need him to point it out.
You have singlehandedly assured that JB Weld will be around for another 50 years. This was incredible and this coming from someone who remembers when this product hit the shelves. Everyone should have JB Weld in their tool kit and in every car or truck you own.
i have a '74 Jeep CJ5 that previous owner had the motor rebiult b4 i got it. there was a crack in the block just under and back from where exhaust manifold connects to exhaust when looking from side. it would weep a little coolant, but not an unheard of issue. year two of my owning it, i got sick of seeing it so i ground it out just a touch with a cutting wheel, filled it w/ JB Weld and smoothed it over b4 repainting block....that was 16 years ago, has never leaked since and i need a strong light and magnifying glass to find it. good stuff!
@@davidthomas6949 im guessing is has something to do with non biased outcomes. Once you start taking money, they expect their product to be shown in a positive light, or mentioned often.
Jama tut, LOL! That's way beyond my skillset but I know there are others with the tools and skills to do this. Thanks for watching the video and commenting!
Project Farm Thank you for making these great videos. I also have a "real" video suggestion: Put WD 40 into the gastank or Alcohol. *Spoiler* produces big clouds and flames xD
I was thinking, What if after you made the head you then coated it with a layer of a metallic substance to protect it from burns, like an aluminium foil barrier only a little thicker.
The bunk of the head needs to be kept cool so some fins are in order. If JB Weld sticks to aluminum foil, just the foil would be enough. The thing the foil would be doing is keeping the burning chemistry away from the epoxy. A thin layer would do that perfectly well. Thicker metal my pop off the surface as it heats up.
JB weld is pretty good stuff ! I had a 2000 E-150 with a coolant leak. Its a "dealer only" part in an extremely tight space(entire intake manifold off to fix correctly) that was leaking right where the part(just a threaded pipe) screws straight down into the block. I 1st tried RTV silicone, just glob'n it all around the base & spreading it with a fat wire bc fingers couldn't even really reach all around it. That lasted a few weeks. the 2nd time I tried an epoxy putty & that only lasted a few weeks. The 3rd time I used JB & its still holding after nearly a year.
Caleb, Yes, I placed the washers close enough together to allow the spark plug to be adequately grounded instead of running a wire. I thought viewers would enjoy the light show as much as I did. Thanks for watching the video and commenting!
Came here to comment about the plug, saw it was already addressed. Good job internet. I would run a ground wire to the plug next time. Your spark, while present, isn't good enough to get proper ignition. The engine had several moments where it was running rather rough. With a proper ground wire ran, this problem will go away.
In the Army we had a proprietary form of Epoxy with shreds of titanium in it for strength. We used it for repairs on the engines of tanks, APCs, trucks and just about anything else that required that the repair endure immense amounts of stress, such as a 427 blown Chrysler Hemi Diesel crank bearing housing in the back of the block. One enterprising young feller even made a barrel for an M-3 grease gun from it, and it did yeoman's duty for about 6 magazines. We decided that he'd proved his point and I personally destroyed it.
I just used JB Weld to repair a hole in an automotive seat mounting bracket to avoid welding. It worked perfect. Great demonstration BTW Always enjoy your videos!
You did not provide an electrical contact between the spark plug's thread and the mass. So you can see sparks between the big washer and one of the head's bolt - some part of ignition power wasted there. Aluminum is a good conductor, JB Weld - not.
Tyler, LOL! Yes it is! Yes, I had a lot of time invested in this video! Several hours of video footage too. Thank you for the comment and for watching the video!
You are an extremely clever guy. I watched you very carefully how you did different tasks and you're totally professional. It's nice to know and also from the point of mechanical things, of course, we should always use them within the parameters for which they were designed. What you have shown is that amazing things can be done and motors can survive an awful lot. Most people I know, never change the engine oil in a mower. Just think how much hassle the engine has to deal with, with owners like that. You asked what kind of additive you should test since you are very sceptical about them. I'd like to see Ceramizer tested to see if it can really repair scores in bore or piston and to what extent can it do that say with a very old engine. How far can it really restore all the old wear damage, the light scoring and so forth?
Brilliant vid. Since I saw your first JBW test, I have repaired Land Rover body panels with it and today I plugged a crack in the grip of a cheap handheld spot blaster. Definitely a toolbox must have - thank you. 🙏
I have to say, although this video is three years old I think it's the best video of all times. From scratch you've made a freaking head that worked, man that's bad ass. This video goes as #1 in your hall of fame of all your videos. In fact, I think you should get your viewers to judge what videos should make it and why. Just a video idea for you to kick around. Yea, you have my vote and why on this video being #1 in your hall of fame of best videos, this one is bad ass I tell you.
Im starting to see no end to this experiment. How many holes can be fixed ? Maybe a new hole in a motor every week until it cracks open only to JB it back up again :D
a month ago you had 4k subscribers. I looked again today and you have almost 20k! keep up the great work. I love your videos! glad I can say I was a subscriber from the beginning
Shaun, Thank you very much for the encouragement! I'm having a lot of fun creating videos and interacting and learning from commenters. I'm excited about several upcoming videos! Thanks again!
Project Farm I seriously can't wait to see where you are a year from now. hopefully making money on RUclips doing what you love!! if you aren't. ALSO, I know this would be a lot of videos and take a little bit of time but I read about top tier fuels being "better" for your engine as opposed to non top tier. because of this, I started using Shell Nitro 93 octane fuel. just curious if there is any truth behind that. I think it would make a good mini series!
hard to test fuels on a mower, they arnt fussy, the mower will run fine on 87 octane, so will most cars, 93 octane isnt needed on most cars at all. it wont do much for the engine, but sure shell might be using other additives that are better than another brand, more cleaners etc to prevent varnish, but that would take 10ks of miles and a control to know, certainly here in the UK supermarket fuels are always having issues with contamination but not so the major brands such as shell/esso etc
Jusb1066 I'm sure the 93 octane is aki and not the American used Ron index. 93 for him might be migrade in America. I still agree with your point though. Lawn mowers don't care enough. I noticed I get poorer gas mileage from Chevron. Less additives means going farther per tank. lol Shell has similar gas mileage to cheap gas. I'm more confident with Shell's research though.
Was using jb weld Years ago. A guy with A caterpillar dozer jb Welded the block, when it Cracked in cold weather. Worked fine for years. Great product 👍
Would have liked to see how long it would have lasted! I also was curious as to how you made that spark plug work considering they usually use the metal they screw into ALSO as the conductor of the negative polarity of the power that make im them spark. Did you achieve that through those two adjacent metal O rings that sit on top of your homemade cylinder head, one of which sat around the spark plug? (BTW, is an O-ring the same as a washer?)
If you rewatch the video, you can see the washer under the spark plug is sparking across the washer held in by the head bolt, that's how it's working. Not exactly safe, but it works.
Hello PF, The various tests that you’re conducting are very basic by design but pure genius in the well thought out way that you conclude your test and present the amazing results. What you’re doing could be called a scientific art form for the logical mind. You explain every step of your project in a way that even the self proclaimed web experts should be able to understand. And above all else, on the rare occasions that you make a mistake , you don’t hesitate to mention it and that speaks volumes about your integrity. I ran across your ingenious activities by chance while browsing through this sea of brain dead geeks doing silly things to amuse their simple minds. Now I’m having a difficult time attempting to move on to anything else. Your projects yield results that can used
I've seen jb weld perminantly seal a cracked sbc 350 from frozen water Crack. Still going after 4 years daily driving... Seen a Honda 50 dirtbike with a hole in the crankcase last for at least 5 years. Repaired a leaking radiator with it as well. This stuff is seriously tough man! Thanks for your hard work, absolutely incredible
Siniestro Siniestros The aftermath is at the end of the video. I really like comments. They can help us if we missed something. It's a very brief picture at the end.
First of all, I love what you do. You're one of the most informative channels on youtube....... I just wish you'd have run the head until it failed. I'm curious to see how long it would last.
JB Weld for gas tank cracks, is beyond phenomenal ! Gas or diesel, steel, or plastic tanks, JB Weld has my vote, and has saved a number of my customers $100's of dollars ! Can't say enough good about it !
"Alright guys, i want to keep this channel for scientific purposes and for information. Now lets make a cylinder head out of JB Weld" i love this channel😂
I used JB to weld a broken / cracked exhaust manifold on my crownline boat! It worked great. JB might not be perfect in all applications, but with good preparation you might be surprised! I have even bonded and then machined parts. It’s great stuff!
pla is far to weak. but lulzbot makes a bronze/pla infused filament that I'm sure with 100% full density settings and maybe a later of jb weld between the filament tolerance gaps it would perform well. it is very strong and if lightly shaped with a blow torch and polished looks pretty Damn cool
PLA wouldn't handle the temperatures. Tho it might run for a short bit. I've seen rocket motors made with PVC pipe as the casing which were quite successful but they only burn for a few seconds tops and the propellant burns from the inside out which keeps the heat off the casing until it is about burned out.
I just used jb weld slow set to glue anchor bolts into the broken lifters inside ford focus 1.6tdci. They broke off half way down when I tried to extract them. Tried super glue, tried gorilla glue epoxy neither held up but the jb weld got the job done wish i had of videoed it was an amazing job which most workshops would of said cylinder heads scrap thanks for your tests on jb weld that gave me the chance to use it great job.
Is this a ploy to build some good karma. Destroy all of your neighbors lawn mowers, so now you are producing lawn mower parts? I would could have never imagined a JB weld head. Awesome project and another fine video. Good luck topping this one. (Bamboo connecting rod????) Thanks. R.J.
I bought a Honda XR500R dirt bike cheap where the engine case had been cracked and repaired with JB Weld by the previous owner a few years before I bought the bike. On this bike, the engine also serves as a stressed member of the frame. I had it for 5 years and never had a problem with it and later sold it to someone else. That proved JB Weld's strength to me.
likely, JB Weld had OP not show us this. awesome product, good videos by Mr Project Farm, but JB Weld was never purposed for this....one minute proves it's more than adequate for a temp solution IMHO
This is probably the most impressive project farm video of all, some achievement. Didn't see any oil used to lubricate the thread tapper, not sure if JB weld is self lubricating, light engine oil is what I use.
why just one min why didn't you let it run for long btw you should have checked if engine is overheating with this head as this won't be a good conductor of heat and due to bad heat transfer engine could over heat
Wide open throttle, Great question! I don't wan't to hurt this engine. I need it for future videos. There's no way for JB Weld to disperse the heat. I don't care about the JB weld as much as I do about safeguarding the engine. Thanks for watching the video and commenting!
Project Farm What about milling some fins for a heat sink? Not asking you to destroy the engine, just monitor the temperature and end the test when it gets to a certain level.
fins wont help, jb weld doesnt conduct heat like aluminium , its gonna get so hot in there to damage the bore/piston, which is why he stopped it, fair enough, we know something gonna fail, jb weld did what it needed, lets enjoy it
ropo_3000, LOL! That's well beyond my capability, but it would be interesting to see if that could be done! Thanks for watching the video and commenting!
Years ago I had a tiller that had a tree limb fall on it braking the carburetor and half of the bolting surface off of the block. I used a toilet paper to reform the intake hole and painters tape to make a form then poured JB weld in to "recast" the block then filed it down and tapped the mounting hole. That lasted 7 years. I must say that $5.00 worth of JB Weld paid off time and time again.
I didn't run it until it self-destructed, but it wouldn't have lasted too much longer since it doesn't efficiently dissipate heat and the max temp rating is only 500F. Thanks for commenting.
I just recent saw they make jb weld paste extreme temp that says it holds up to 2400 degrees. that might do the trick longer. I just don't know how it is in paste form. I'm going to try some on old jd A manifold to build up where the exhaust pipe connects to it. its rotted away and doesnt seal right. I have muffler putty stuff there but doesnt last.
When I was a kid, I bought a broken CR125 dirt bike for $100 because it had a huge hole in the side of the block a little larger than the size of a quarter from the motor bottoming out on a larger bolder rock. I was only 13 years old but had a lot of experience from doing stuff with my dad. I used JB Weld to fill the entire hole and then a dremel to shape it perfectly. Never leaked oil and ran great for years and then sold it for $1,500.
Project Farm Yeah. I didn't think so. Making the inside of something round is a lot easier than having equipment which does that on the outside of something!
UnleashNinjaGuru I thought he just repaired a cylinder head and made one? Has he used it on piston pitting? I didn't see pitting on any of his engines...
I know this is old but thanks for doing these types of things. These ideas do cross our minds as we work with this stuff (JB Weld, Glues, Mechanical Item, etc.) but we do not have the time to satisfy our curiosities. Now you do it for us. THANKS!
Well done. I like your videos! I used JB weld to fix a crack on an OMC outdrive and it worked great. Sand away the rest and paint over it and it’s so solid.

it already does obviously but its cheaper to use epoxy than metal for mass production
how do you figure that it's cheaper to use epoxy than metal for mass production...?
On what planet is epoxy cheaper than metal? It certainly isn't Earth

To be fair it would probably be cheaper to manufacture. No high temp furnaces or machining. Just casting.

Ever use aluminum jumper cables? Aluminum is NOT a good conducter...try copper
Aluminum is fine as a conductor. Copper and silver are better, but there are tens of thousands of miles of aluminum transmission lines in use.
I saw that too. You could see the sparking between the washers brightest when it misfired.
@@jakemclean7563 aluminum is a great conductor and way lighter than copper. Some airplanes use aluminum wire for weight savings.

This video goes as #1 in your hall of fame of all your videos. In fact, I think you should get your viewers to judge what videos should make it and why. Just a video idea for you to kick around. Yea, you have my vote and why on this video being #1 in your hall of fame of best videos, this one is bad ass I tell you.
maybe you should drill a hole in a piston and try to fix it with JB Weld. Wouldn't that be a great idear? :D
DennisMeier911, Great suggestion! Thanks for watching the video and commenting!
Im starting to see no end to this experiment. How many holes can be fixed ?
Maybe a new hole in a motor every week until it cracks open only to JB it back up again :D
ProCactus build an engine out of jb weld
My dad once had a car that blew a hole in the piston. He JB welded a 50 cent piece over it and got another 20,000 miles out of it
Your dad is a mad man. Sounds like a swell fella.
Years ago I got convinced about JB weld when I watched a guy repair an aluminum AC condenser with it. Great Vid I watch your Vids all the time.
Thanks! Thanks for watching!
a month ago you had 4k subscribers. I looked again today and you have almost 20k! keep up the great work. I love your videos! glad I can say I was a subscriber from the beginning
Shaun, Thank you very much for the encouragement! I'm having a lot of fun creating videos and interacting and learning from commenters. I'm excited about several upcoming videos! Thanks again!
Project Farm I seriously can't wait to see where you are a year from now. hopefully making money on RUclips doing what you love!! if you aren't. ALSO, I know this would be a lot of videos and take a little bit of time but I read about top tier fuels being "better" for your engine as opposed to non top tier. because of this, I started using Shell Nitro 93 octane fuel. just curious if there is any truth behind that. I think it would make a good mini series!
hard to test fuels on a mower, they arnt fussy, the mower will run fine on 87 octane, so will most cars, 93 octane isnt needed on most cars at all. it wont do much for the engine, but sure shell might be using other additives that are better than another brand, more cleaners etc to prevent varnish, but that would take 10ks of miles and a control to know, certainly here in the UK supermarket fuels are always having issues with contamination but not so the major brands such as shell/esso etc
Jusb1066 I'm sure the 93 octane is aki and not the American used Ron index. 93 for him might be migrade in America.
I still agree with your point though. Lawn mowers don't care enough. I noticed I get poorer gas mileage from Chevron. Less additives means going farther per tank. lol
Shell has similar gas mileage to cheap gas. I'm more confident with Shell's research though.
Good job, glad it ran so well !
ChargerMiles007, Thank you very much! By the way, I really like your channel! Your craftsmanship is phenomenal!
Was using jb weld
Years ago. A guy with
A caterpillar dozer jb
Welded the block, when it
Cracked in cold weather.
Worked fine for years.
Great product 👍
I used JB to fasten a cooling hose in the manifold of my 4.6 Ford truck. It has ran tens of thousands of miles. Great stuff!!!!
Thank you!
Would have liked to see how long it would have lasted! I also was curious as to how you made that spark plug work considering they usually use the metal they screw into ALSO as the conductor of the negative polarity of the power that make im them spark. Did you achieve that through those two adjacent metal O rings that sit on top of your homemade cylinder head, one of which sat around the spark plug? (BTW, is an O-ring the same as a washer?)
If you rewatch the video, you can see the washer under the spark plug is sparking across the washer held in by the head bolt, that's how it's working. Not exactly safe, but it works.
"With a ratchet you're most likely to keep it straight."
Taps it at three different angles.
Just razzin' ya.
lol. Great point
Hello PF,
The various tests that you’re conducting are very basic by design but pure genius in the well thought out way that you conclude your test and present the amazing results. What you’re doing could be called a scientific art form for the logical mind.
You explain every step of your project in a way that even the self proclaimed web experts should be able to understand. And above all else, on the rare occasions that you make a mistake , you don’t hesitate to mention it and that speaks volumes about your integrity.
I ran across your ingenious activities by chance while browsing through this sea of brain dead geeks doing silly things to amuse their simple minds. Now I’m having a difficult time attempting to move on to anything else. Your projects yield results that can used
Thank you very much for the positive comments!
I've seen jb weld perminantly seal a cracked sbc 350 from frozen water Crack. Still going after 4 years daily driving... Seen a Honda 50 dirtbike with a hole in the crankcase last for at least 5 years. Repaired a leaking radiator with it as well. This stuff is seriously tough man! Thanks for your hard work, absolutely incredible
Impressive repair!
Amazing experiment, I was hoping you were gonna run it until it broke and/or show us the aftermath. Keep those videos coming.
Siniestro, Thank you for the comment and for watching the video!
Siniestro Siniestros The aftermath is at the end of the video. I really like comments. They can help us if we missed something. It's a very brief picture at the end.
First of all, I love what you do. You're one of the most informative channels on youtube....... I just wish you'd have run the head until it failed. I'm curious to see how long it would last.
Thank you
That was awesome experiment.
Thank you!
Wow .The dedication that you put into your projects and testing is absolutely amazing. Thank you
You are welcome!
I have used JB weld for alot of years and love it, If they dont endorse your video something is soooo wrong!!!!
Thanks you! Happy New Year!
Eventually, an entire car from JB Weld...
Jeffrey Hurst Radio with a Nokia 3310
Needs a Bondo body.
Love the hard work and dedication you put in your videos keep it up
Thanks, will do!
JB Weld for gas tank cracks, is beyond phenomenal !
Gas or diesel, steel, or plastic tanks, JB Weld has my vote, and has saved a number of my customers $100's of dollars ! Can't say enough good about it !
Thanks for sharing.
That's so cool ,I would have liked to see it's failure point. Future video?
supersportryder, Great idea for a future video! Thank you for watching the video and commenting!
"Alright guys, i want to keep this channel for scientific purposes and for information. Now lets make a cylinder head out of JB Weld" i love this channel😂
Thank you!
JB WELD AMAZING JOB INFORMATIVE TESTING 💯👍🏻🇬🇧
Thank you!
I used JB to weld a broken / cracked exhaust manifold on my crownline boat! It worked great. JB might not be perfect in all applications, but with good preparation you might be surprised! I have even bonded and then machined parts. It’s great stuff!
JB is a great product!
Wish I had tools like yours. I couldn't take my eyes off the screen when it was running. Great video.
Thanks for watching!
Try this aero space epoxy.
EA 934NA
Aka metal set. That stuff works miracles
It’s similar to jb weld
Thank you!
You seem like a genuinely great guy and your reviews/ tests are hands down the best scientific tests on RUclips
Thank you very much!
You are impressed with J.B. Weld and I am impressed with your ingenuity. Thank you for your public service
Thank you
Well, I'm sold on J.B. Weld! :D
David, Thank you for watching the video and commenting!
I don't know if it was already suggested, but try it with "Belzona 1111 Super Metal" also a very good epoxy material
Manuel Lagast I was going to say the same thing. Hold on to your wallet tho! Do not breath the dust from Belzona! It can kill you! Good stuff!
Very nice! Maybe consider trying a beefy PLA 3D printed cylinder head?
Keegan, Great suggestion! Thanks for watching the video and commenting!
pla is far to weak. but lulzbot makes a bronze/pla infused filament that I'm sure with 100% full density settings and maybe a later of jb weld between the filament tolerance gaps it would perform well. it is very strong and if lightly shaped with a blow torch and polished looks pretty Damn cool
PLA wouldn't handle the temperatures. Tho it might run for a short bit. I've seen rocket motors made with PVC pipe as the casing which were quite successful but they only burn for a few seconds tops and the propellant burns from the inside out which keeps the heat off the casing until it is about burned out.
Keegan Thomas PLA starts to melt at 100°C so it wouldn't last long
I just used jb weld slow set to glue anchor bolts into the broken lifters inside ford focus 1.6tdci. They broke off half way down when I tried to extract them. Tried super glue, tried gorilla glue epoxy neither held up but the jb weld got the job done wish i had of videoed it was an amazing job which most workshops would of said cylinder heads scrap thanks for your tests on jb weld that gave me the chance to use it great job.
Glad to hear! Thanks for sharing.
It would have been interesting to see a long term test with this. 5-10 minutes running, multiple cycles cooldown cycles (we'd take your word)
Thank you!
@@ProjectFarm odd canned response but I appreciate the effort to stay connected on a big channel
I was wondering how you were going to ground the spark and then I saw it arcing to the head bolt for ground
Daniel, The washers weren't quite touching, which resulted in the "light show". Thank you for watching the video and commenting!
would double like if I could! thanks for taking the time for this experiment. if I wasn't already subbed, I would be now!
I've never used JB Weld but after your two videos on the topic, I love JB Weld and will be using it in the future.
Thank you very much!
Is this a ploy to build some good karma. Destroy all of your neighbors lawn mowers, so now you are producing lawn mower parts? I would could have never imagined a JB weld head. Awesome project and another fine video. Good luck topping this one. (Bamboo connecting rod????) Thanks. R.J.
R.J.'s workshop, LOL! Bamboo connecting rod...LOL! Thank you for the positive feedback and thanks for watching the video!
R.J.'s workshop how about a JB weld piston? Yes, the whole piston!
R.J.'s workshop - bamboo connecting rod? Didn't the professor already do that on Gilligan's Island? Lol
+Sun Mountain Automotive It would be so out of balance you would break a main cap.
6:22 I like this technic bc you can keep it straight. Doesnt look so straight to me :D
"I like to use a ratcheting tap piece to keep it straight..." it's as crooked as a politician.
No shit, that is way crooked.
its the way you hold your head looking at the screen
@Kenneth Boyer its not you can see on time lapse he turns it to straight...
its all perspective....i prefer to see it as straight as a rare politician
Doesn't matter, he screwed in the spark plug crooked as well, that will even it out xD
Some one needs to pickup a clapped out Bridgeport
Haha jb weld apex and side seals
I bought a Honda XR500R dirt bike cheap where the engine case had been cracked and repaired with JB Weld by the previous owner a few years before I bought the bike. On this bike, the engine also serves as a stressed member of the frame. I had it for 5 years and never had a problem with it and later sold it to someone else. That proved JB Weld's strength to me.
Thanks for the feedback.
Can you try graphite in the oil? i heard there was this old oil that had graphite in it.
Corrosion37, Great suggestion! As luck would have it, I have a giant container of graphite in the shop! Thanks for the suggestion!
Anyone else notice his drawing on the cylinder head kind of ended up looking like a pregnant lady? Just saying. Great video!
802 Garage, LOL! Thank you for watching the video and commenting!
What did the cylinder head look like when it was removed and inspected?
9:48
yup ! I also wanna see inside
I watched to the end hoping to see the tear-down. Did the JB Weld melt or otherwise take heat damage?
likely, JB Weld had OP not show us this. awesome product, good videos by Mr Project Farm, but JB Weld was never purposed for this....one minute proves it's more than adequate for a temp solution IMHO
+ Andrew Skrzenski and Ronald Jensen 9:48
This is probably the most impressive project farm video of all, some achievement.
Didn't see any oil used to lubricate the thread tapper, not sure if JB weld is self lubricating, light engine oil is what I use.
Thanks!
why just one min why didn't you let it run for long btw you should have checked if engine is overheating with this head as this won't be a good conductor of heat and due to bad heat transfer engine could over heat
Wide open throttle, Great question! I don't wan't to hurt this engine. I need it for future videos. There's no way for JB Weld to disperse the heat. I don't care about the JB weld as much as I do about safeguarding the engine. Thanks for watching the video and commenting!
Project Farm What about milling some fins for a heat sink? Not asking you to destroy the engine, just monitor the temperature and end the test when it gets to a certain level.
+Stacy Smith Curiosity has killed the cat. Protecting the face may not be adequate even with the protection he used.
In the last seconds of the video look at the condition of the JB weld..... I don't think it would last another minute.
fins wont help, jb weld doesnt conduct heat like aluminium , its gonna get so hot in there to damage the bore/piston, which is why he stopped it, fair enough, we know something gonna fail, jb weld did what it needed, lets enjoy it
Nice video, keep the good work
Harold, Thank you for the positive feedback and thanks for watching the video!
next: whole engine made of J-B weld😂😂😂
ropo_3000, LOL! That's well beyond my capability, but it would be interesting to see if that could be done! Thanks for watching the video and commenting!
I get the feeling the rings would destroy the material, assuming you could polish the jb weld well enough to even seal.
yeah, i think you would have to run at least a sleeve if you made a whole block out of jb weld.
SOCAL3800 then I'd be worried about the sleeve expanding and cracking the block. at least it'd be cool for a little while.
Years ago I had a tiller that had a tree limb fall on it braking the carburetor and half of the bolting surface off of the block. I used a toilet paper to reform the intake hole and painters tape to make a form then poured JB weld in to "recast" the block then filed it down and tapped the mounting hole. That lasted 7 years. I must say that $5.00 worth of JB Weld paid off time and time again.
Thank you!
Did someone else see the little drawing mishap at 4:45 - 😅
Boobs and belly?
Try adding some metal into the ix and see how well it lasts :D
Thank you for this recommendation!
So how long did the cylinder head last?
I didn't run it until it self-destructed, but it wouldn't have lasted too much longer since it doesn't efficiently dissipate heat and the max temp rating is only 500F. Thanks for commenting.
awesome
I was really hoping to see how it failed. I was banking on it cracking near the sparkplug.
I just recent saw they make jb weld paste extreme temp that says it holds up to 2400 degrees. that might do the trick longer. I just don't know how it is in paste form. I'm going to try some on old jd A manifold to build up where the exhaust pipe connects to it. its rotted away and doesnt seal right. I have muffler putty stuff there but doesnt last.
Cody K that would definitely be a cool experiment
When I was a kid, I bought a broken CR125 dirt bike for $100 because it had a huge hole in the side of the block a little larger than the size of a quarter from the motor bottoming out on a larger bolder rock. I was only 13 years old but had a lot of experience from doing stuff with my dad. I used JB Weld to fill the entire hole and then a dremel to shape it perfectly. Never leaked oil and ran great for years and then sold it for $1,500.
Nice!
Anyone else catch a “Hank Hill” type vibe from this particular video?
lol. Nice
I like the fact you’re doing these things for “science” so We don’t have to..
Next video: making a cylinder head from a weld.
JB Weld is great stuff. My dad rebuild a steering box for a tractor with it once and I fixed the coolant overflow tank on my dirtbike with it.
Impressive!
4:52 I thought I just switched to visual politik
Try doing that with an ohv engine next lol
spratsprat, LOL! That's beyond what I'm able to do for sure! Thanks for watching the video and commenting!
When I first heard the title, I thought how in the world? ...I was assuming OHV! But a flat head is another matter!
100% JB Weld piston? Try it please
Shivering Cat, This is a great suggestion, but I don't have the setup to do this. Thanks for watching the video and commenting!
Project Farm Yeah. I didn't think so. Making the inside of something round is a lot easier than having equipment which does that on the outside of something!
Shivering Cat ChargerMiles007 already did it
UnleashNinjaGuru I thought he just repaired a cylinder head and made one? Has he used it on piston pitting? I didn't see pitting on any of his engines...
DE Nichols
/watch?v=n2Wp-7kqEKI
I know this is old but thanks for doing these types of things. These ideas do cross our minds as we work with this stuff (JB Weld, Glues, Mechanical Item, etc.) but we do not have the time to satisfy our curiosities. Now you do it for us. THANKS!
You are welcome!
I want to see a cylinder head made of stone or concrete.
Solid Marble cylinder head. Full luxury head for a flathead engine.
Seems like it would be prone to fracturing with high heat, no? You ever see a rock around a camp fire?
@@ToastReaper seen rocks in camp fire. Only certain types crack.
lol... bit primitive
I would like to know the time to failure.
Thank you for this recommendation. I didn't run the engine until failure, but it wouldn't have lasted much longer. Thanks again.
That was the most crooked tap job I've ever seen lol.
lol
Well done. I like your videos! I used JB weld to fix a crack on an OMC outdrive and it worked great. Sand away the rest and paint over it and it’s so solid.
Impressive repair!
Run slick 50 in airplane engine then drain the oil and fly it from Tampa to Atlanta
🤣🤣
Try concrete!
Thank you for this recommendation!
Michael C This is an excellent idea. There are some very strong concretes. >5000 psi in fact. It also conducts heat better than wood and plastic.
It would be hard to get the shape tho
I was thinking the same thing.
way too brittle
Drill press bro. Would've made creation easier and more precise
Thank you
