That was great to know. I have used JB Weld in the past and I saw where you could drill and tap it but I always wondered how strong it really was. After seeing it took over 1 ton to move the bolt I am convinced it is as strong as it is advertised. Thanks for conducting this experiment and providing us this information.
Man JB-Weld is amazing. One time while I was doing handyman work, I had a customer who needed a bunch of things done. She had a slop sink in her garage and the faucet corroded in one spot, making some small holes and causing it to leak. I suggested changing the faucet, but she said “can you just fix this one?”. I said “sure, I think I have something but it’s not going to be pretty ”. I shut off the water, took the faucet off the sink, made sure it was completely dry…filled the small holes with some JB-Weld and let it dry, until I came back the next day to finish doing some touch ups with the painting I did for her. I put the faucet back on and sure enough it didn’t leak anymore. Like over a year later the same customer called me back out to small hole in her in her drywall. After I did the work I used that same slop sink to clean my spackling knife and paint brush…it still wasn’t leaking! I’ve put a lot of faith into JB-Weld since then lol
Generally the longer epoxies take to cure the stronger they are. Cleaning the parts as mentioned is really important. Broken castings, especially cast iron, are porous and will absorb oil so you have to be aggressive when cleaning. Several tricks are helpful when doing repairs. Castings, metalic or plastic, usually fail at a high stress point and epoxy alone won't make a lasting repair. If possible, like repairing a badly broken bone, install pins in the work to provide strength to the joint. In plastic repairs, drill the holes for the pins slightly undersize. Heat the pins (or something like clothes hangar wire) and plunge them through the holes for a tight fit. A common problem is holding odd shaped work while the epoxy sets up. Here super glue and auto weather stripping contact cement are your friends. Use small amounts of glue or cement in several spots to bond the work together while the epoxy sets. Cheers from NC/USA
Fantastic video scout.. love the bench tests, hope Jb weld picks up on your thorough and accurate testing on this application! And at the very least gives you a lifetime supply of it 😂😉👍 cheers Rob
Hi John. JB is great stuff. My Farmal B had a cracked head. Arnold Auto Parts Machine Shop patched it with JB. I drove it 10 years last I knew it was still running after 20 years. Good experiment. 😁😎👍
I work in a real hardware store and whenever customers want something that is durable and long-lasting, we always recommend JB Weld. And we sell a boatload of the stuff. With a good hammer, a pair of vise-grips, some duck (duct) tape, a good flashlight, WD40 (or 50-50) and JB Weld, a homeowner can take on a myriad of home repair issues. Keep up the great work! Jim
Great JB weld demonstration. I’ve always said that JB weld doesn’t get enough credit for what it is. It’s been around forever. Long story short. Tough times, hole in my radiator on the plastic fill spout. JB weld held until I could buy a new radiator. It’s a great product.
Good information today! I have heard of a guy that used JB weld to fix a cracked water pump and it held for years. Thank You for sharing John ! Have fun this weekend 😃
Been thinking about this and I'd just do it like this for ME, nobody else but put the JB inside the bore after I cleaned it up and maybe drill a small hole out the bottom to let the excess pressure off when I screwed the screw into the pretty much JB filled hole and coated screw and assemble it totally right then. And I hope JB changed their formula because it used to couldn't handle ethanol in gas AT all. I used it to seal off pinholes in Briggs 5 horse gas tanks. Now I use a blob of Seal-all and no leaks after years of run time in mowers and splitters. Happy week, John! God Bless!
I remember back when I first used JB Weld was because people talked about someone fixing a cracked or broken block on a bulldozer with it. I think the only place it failed was on exhaust. Almost anything short of welding doesn't hold up on exhaust. I use JB Weld more than duck tape. Like any epoxy including body filler like Bondo, surface prep is everything.
@@geraldschrader8511 I tried it. Didn't last more than a few days. A mig or replace it are the only lasting solutions. Now it might hold better on a straight up tractor exhuast but not well on curves and even straight line under a vehicle. Funny thing I had a bunch of pin holes in a motorcycle gast tank. I bought a special mix putty for fuel tanks. It started leaking in a day. So I cleaned everything back and coated the area with JB Weld and it has held up for years. It's kind of a you have to be patient and see if it works. In the 50 years I have tried many ways to patch mine and others exhaust with every type of product sold and only welding will get something that will last more than a month. Mig, Tig or using a gas torch will get you there with some practice.
Thanks John, this was a really instructive post, the discussion of the options at the beginning was really informative, and the demonstration of the JB Weld also ! Have a great time at Jacktown, I wish I could join you !
Great video 👍 The demo and information you gave on J-B Weld was fantastic!! ✅ That epoxy is really great stuff. We all got to see the Dake in action. Even though the epoxy was no match for the Dake , it was Impressive that putting 1 ton of pressure on the threads 🔩 and you can still screw in the bolt nicely. Well again great video and can’t wait to see what you do on Friday. 😄👍👍
Hi John. I have used j b weld many times. On numerous occasions. I even had a 9n Ford tractor that I repaired the cracked block with it. Great stuff. Would not be without it in my shop. Have a great rest of the week. 👍👍❤...
Jb and quick weld epoxies I use for all kinds of stuff. The wood and plastics ones as well work great!! Like all of them, you just gotta prep stuff before you use these for best results
you used a bamboo skewer, I have a supply of chop sticks from Chinese take out, paint stirrers from Home Depot, and wooden ice cream spoons from Dixie cups for my disposable glue applicators.
I punched a hole in my oil pan out on the Red Desert of Wyoming. To save myself a 20 mile walk to the nearest county road I used JB Weld to patch it up. I drove that truck another 100k miles with no problem or leaks. Should hold a little bolt like that.
JB weld looks to be a good product, I have never used it myself, but if a situation arises I will give it a try, let you know how it pans out. Like your testing method with the bolt and treads. Thanks for the feedback sir, found it interesting.
JB Weld is awesome stuff. It has saved my projects numerous times. However, I use it only as a last resort because I look at it as a bandaid. Sometimes a band aid is exactly what is needed.
Thanks for this. I just messed the threads up on my Ferguson carb trying to drill the sized needle seat out of the body. Going to try and fix it this way.
Hey scoutcrafter my grandson Landon and I watch your videos all the time. He's just 6 years old and loves to find Snoopy. Landon just join Cubscouts this year and he was wondering if you'd ever do an episode on making the pinewood derby car.
For me JB weld has always been my go to right off the bat. I don't like wasting a lot of time messing about with trying "this or that" I know it'll work and it will hold, as you've proven here. Great video for those that didn't know...and dont you just love it when you are right?! Lol!
Great information, lots of younger guys have trouble hearing wisdom. I have used JB weld and have had trouble, but it was all ways my fault. Bad job cleaning or being impatient. Great video, I am sure lots of people will benefit from your lessons.
Your idea and test just proves your concept I like it, one thing in his situation makes me wonder is if the threads are filled with brass remnants in the threads if that might cause an issue of adhesion during the tapping if it might not bite in because the brass is not stuck the cast iron in a sense that it is not fused together? I honestly can’t help overthinking lol.
Hi Scoutcrafter the JB weld will continue to get harder even after 1 day. if you didn't have a tap and die set you could put some JB weld on the bolt and in the hole when it is still wet. if you wanted to get the bolt out again you maybe would have a problem that way
I love JB Weld. I also love the packaging with separate tubes. I have very bad luck with any 2 part epoxy with a syringe style package. Most of the time one of the two sides of the syringe does not dispense the product so I either waste a lot of product, or I do not get a good mix. JB Weld and many other epoxies are approx 1:1 mix ratio, but if you mix too much of one part with too little of the other, then sometimes the result will be weak and sometimes the result will not cure. Dave.
Great test of the jb weld I use that stuff so much it’s fantastic and actually have to use some tonight to glue a small loose wire lantern hanger back on my Dietz beacon that fell out while I was polishing it
Thanks Scout ! I Knew JB Weld was Great . I've Been Using It A Long time . I Always Keep It Handy I Have The Big Tubes Now Brand New. Vise Grips Essential You Bet . I've Been Using Them Since I Was A Kid . My Dad Always Had Them and He Didn't Have Many Tools.
You tested those JB Weld threads out in a reasonable way with the 150 lbs on it and it didn't budge. Then you gave it an extreme of 2000 lbs on the Dake. Even though it will get some pressure if used as a scraper it should come close to either of the two weight tests you put it under. Like you I think cleaning out the bore's threads and using JB weld should work to restore the holding power of those handle screws. Good demo on the JB Weld.
You ought to try using a file to create grooves in the aluminum for the JB weld to rest in to prevent slippage and you could also reinforce the JB weld with some sort of shredded fiber material such as carbon fiber or kevlar, shredded kevlar being the best bet. I would love to see a new video with that twist.
Would be interesting to see how much torque it would take to either strip the threads or break the bolt. By the way I ordered a Cresant knife. Thanks for doing these videos.
"Snoop" @ rest...that old school Army green wool blanket that I have neatly folded on my passenger side front seat of my 2004 Outback gets wash on occasion by using 1 cup of ammonia per instruction on the ammonia bttl...tanks for sharing
My sister and I were on a road trip 1000 miles from home. We were driving along and the car in front of us flips up a little stick, like the size of a twig. I felt it hit the bottom of our car. Lo and behold, we noticed the gas gauge going down way faster than it should have. We found our way to a store and bought the two part epoxy putty for gas tanks. It's like chewing gum. I took a wad of that and stuck on the bottom of the tank and it worked! It was still like that when she sold the car like 5 years later. I was an instant convert and now I never have a car without that in my tool kit.
Always wondered on JB Weld. As far as ebay, as you've said before, buyer beware...sellers can claim a lot, but it's a hassle when what you ordered is not.
A Great Teacher is one where people have fun learning something, and didn't know that they were learning something! You are a Great Teacher! The Prince of Nigeria is mailing you a check for 47 million dollars! =P
Great test. I’m sure that kind of fix will be more than sufficient for the use of that tool as most of the force being exerted is lateral to the bolts.
Hey Scoutcrafter! please stay away from the kissing booth at Jack Town Saturday. There's some real strange citizens up in P.A. 🤣 That's a call back to a previous video you posted with the kissing booth! I've never laughed so hard. That was a classic 👌 I will never forget the look on your face! Happy tool hunting everyone!
Have a Acme 1/2" × 10 tpi RH lathe compound where internal thread worn. Going to clean all oil out, wax shaft and use JB weld to fill the worn threads then put shaft back in till it sets. Hopefully can remove shaft then. The cost to 'fix' this requires drilling out worn threads, and make another undersized long sleeve nut to be fixed into the slide. Money I don't have, so JB weld.
Hey John, While you're doing tests on jb weld, have you ever heard of using cigarette ashes and super glue to make a bonding mix. If not then check out some videos on RU-vid. It's a good quick fix for a lot of things. Later
JB weld is great. Vice Grips are fantastic. But how can you not mention the number 1 product of all time. It cures all...................... DUCT TAPE!!!!! 😀 Thanks for the great video.
I like the JB weld test. Very good to know. What's your thought on the putty sticks? I've used them for several things and really like them, but never in an application like this.
in lieu of re-tapping a new hole (for those who may not have a tap kit) how about a test where you coat the damaged thread in the hole and on the bolt and fit it down in? I assume this could be just as strong, but you just lose the ability to remove the bolt later.
That was really good to see! You mentioned in your last video about PC Products PC-7 Epoxy Adhesive Paste. Do you think this would be better than JB Weld or would you expect about the same results?
Hi John enjoying your content and the time you spend on researching the smallest details for your projects. You mention Jacktown this Sat. Will they have the tool vendors like the other ones? I plan to go if the weather stay nice will you be sporting your red back pack? Regards Jerry
Jerry- Yes! Not as many vendors as the spring but I've gotten some great deals at the winter show! Plus with today's economy I bet people will be selling more of the good stuff! =D Red backpack and fur hat! LOL
