Well, It looks like I have a couple/few videos that might pique your interest. This was an interesting one. I wasn't quite sure if it would work. so far so good!. Either way, kick back and enjoy these few minutes. Thanks for the support.
If it was easy, anybody would do it or could do it you know it’s like I’ve been a self-employed carpenter for 28 years when you can ring your socks out at the end of the day that’s some serious sweating your balls off
I see you have your little twin working with you. Same shirt, same pants same pen in the pocket. It's good to see father and son working together. This makes great memories for both of you in the future. Great job, as always 👍
Awesome! But my knees and elbows ache now like I have been crawling around on gravel for hours. Hats off to Isaac and crew for continuing to raise the bar.
@@rascalwind The peening de-stresses the metal and strengthens it, and also cools it off, stress in the metal is very common when welding two dissimilar metals like this, regular cold rolled steel, and cast iron .. Stress in the metal causes tension, which makes it crack later, sometimes as soon as vibration gets to it, or when it heats up to full operating temperature, even a few days later. Peening the metal while hot, can eliminate the cracking.
Growing up in the 1970s, I worked a few road jobs building and pouring the concrete forms for water run-off inlets. Back then I took note that every grader operator on our jobs always seemed to have the stub of a chewed-off cigar stuck in the corner of his mouth. Every last one of them. I honestly think it had something to do with how they got so close to final grade on the last pass of their blade. LOL Cheers! Whipple
Excellent repair Isaac! I’ve done a few oil pan repairs…similar situations. You guys watching this probably already know this stuff but maybe this will help someone. Just from experience with these types of jobs. one thing I do to battle the oil when it starts seeping out is hit it with that green non-chlorinated brakekleen, then hit it with air, then weld. The brakekleen will thin out the oil, then the air blows it away and evaporates, then weld it in a timely fashion before the oil seeps back in. It will definitely buy you some time and make your life easier. Just make sure it’s the green can brakekleen. Idk that’s my go to move in that situation.
I do alot of these kinda repairs and this is a nice clean fix for what you have to work with it’s probably the most sound part of the under carriage left lol
You get all the best jobs, Isaac! As a certified old guy, I can confirm that the ground gets harder every year. Also, clothes mysteriously shrink over time. 🤣
Make a bed/mat out of a roll of hardware cloth(1/4" fencing). Fold it so you have 3 or 4 loose layers and about 3 or four foot long. It will both help smooth out the rocks all the while letting sparks and hot bbs to fall through. You'll want to make all the edges smooth and tack them in place so they aren't getting bent and catching on everything. Even putting a garden rake one the truck to prepare the area would help.
Slightly late to viewing this video. Was feeling both of you gentleman’s “pain”, lying down there on all kind of rock(s), arm fatigue/cramps, sheesh. Couple of questions.., (not a welder, but I am getting parts, pieces, and equipment together to do my own around the shop/farm welding, and with your inspiration I will one day be just like you…, hahaha..!), doubtful for sure, I am 60yrs young.., that ship as they say has sailed many years ago… Anyway, I think I understand the stitching is to minimize heat buildup in one area, and warping. Why so quick to needle scale the weld.., is that another way to let the heat escape and not be contained under the slag? Great videos, love seeing junior working with you. Thank you sir.
@@greggb1416i know you're not asking me but nbs welding has a video and i think it mashes the weld while its still red hot to get a snugger fit and close the gap even more. The video i saw he actually used a hammer and demonstrated this. Anyways hope this helps answer your question. ✌️
@@armandhammer9617 Ahh copy that, no problem. I usually include the other viewers in eliciting an answer to my question(s), because I know the content creator can’t answer all the questions. So, thank you. I even wondered about the “sealing” aspect of hammering the hot weld. Thank you sir. And I used to be subscribed to NBS…
@greggb1416 I'm not IC, but the reason for the needle scaler is to peen the weld. He's welding cast iron with a steel electrode. Cast iron shrinks more and faster than steel. So the idea is to lay in a little bead then peen the steel while the cast is cooling off. Peening the steel is like setting the head of a rivet. It swells it out so that it keeps up with the cast shrinking and it won't crack or break....or getting the deadly PLINK!
Again I have learned something new. I was always told that welding cast metal was difficult, but using your method made it look easy. You are a great teacher. It looks like your son is going to follow in your footsteps. He has a great teacher.
Looks to be a Cat 12E model . The 12 F looks close but the difference is the control box is smoother and doesn’t tear your arms off when your turning the circle . I learned to cut grade with the E model then I got a 12F and thought I was on a Cadillac and then I got one of first 12 G articulating blades in California with hydraulics and I knew I must be in heaven .
Overhead, oil soaked, cast, and curves. Pretty sure that's on the welding Jedi test. Very nice job. I also love how you're teaching your son. Seems like that's something that never happens anymore for many reasons. By the time he's your age, this line of work is going to pay more than doctors or lawyers. So few young men going into the trades. 😢
I did that on an engine block years ago and to finish it off I cleaned it real good and put a coating of two part epoxy over the weld area and not a drop of a leak. I was worried about pin holes.
Man of a million tacks!! Amazing, beyond amazing! Get a list of everything you should not do for a good weld and you had it facing you. Man that was a performance.
Overhead and oily!..... always an easy repair for everyone except the guy who actually has to do the repair. Good job as always and even better that you are teaching the next generation how do the difficult repairs as well. As for the seep, they could clean the surface with brake parts cleaner and put some jb weld on the area and the leak would be stopped and it could still be disassembled in the future if necessary. Really enjoy the variety of repairs that you do in your videos, always something new and different.👍👍
I have always compared Welders to Doctors and Mechanics. It seems like the are very few that can do the job right the first time, but when you find that one, it's worth paying what they charge.
I'll never understand why people don't understand that if there's one big rule with these machines, it's to have the same tires on the rear, on the seesaw axle. Different tires wears down the chain, breaks the sprockets, effs up the bearings much faster. You're much better off with two worn tires than two different threads or worn states (one good tire and one bald tire). You're just setting yourself up for an absolutely nasty repair (cause those chains and that box 100% guaranteed will stink your nostrils off like Neo's mouth in Matrix).
As you can see, the top-notch maintenance of the machines is not on the top of their list. The guy tried to jack up a several ton machine under a cast iron gear case! I mean c'mon man! At least put jack on the seam in the case where it's most thickest! 🤔🤷🏻♂️🤦🏻♂️👨🏻🏭🛠️🔩🔧
You are exactly right, the township I grade for has 4 different tread patterns on the rear, the thing leaks like a tea strainer, you can hear the chains slap when you put it in gear, now my transmission just quits working every time I'm pulling a load. Ah , the joy of running a grader that has seen better days 😁
Really great repair! Most would probably make the plate and put it up with JB Weld and a bunch of small bolts. Great team work also that is super nice that you have someone to learn and also help so precisely with the job.
Just found ur channel, I have a natural passion for this work and currently work as a trader, but since a kid iv worked in my fathers workshop this kind of work Is in my blood I love it ❤
Thanks Isaac for the hard work forming those compound curves to weld into those cavities. At least you won't have to drive it with all those manual controls. You would need the forearms and shoulders of an old-style electrical lineman that climbs poles all day by hand. I saw a group of those guys install 8 or 9 security lights on a horse racetrack for SECO in Ocala, FL back in 1984. Those guys had arms like my thighs and I was a tough & fit horse farmer. They would climb those poles faster than a squirrel with just spikes, then hook their belt when they got to the top, then going down was faster. Took them about 2.5 hrs. to do all those lights. Enjoy the brain candy figuring it all out!
It's awesome that you have brought your son into the business with you. Hopefully you can make more videos more often like in the past to get him more experience. Awesome channel guys.
Great patch repair, looks like from factory and nothing happened there! Considering all the oil and dirt present, it turnd out really nice... Nice to see Junior back in action! 👍👍👍
Awesome job repairing that CAT Isaac. It is hard for many welders to make such smooth welds in one continuous pass, but you can tack and stitch an still make it pretty, despite the dirt and oil fighting you every step of the way. It was especially good to see your son back on the job with you. You two work so well together it's blessing to watch you teach him on the job. I figure someday soon you'll have him weldiing the hard to reach places and give your tired arms a break. LOL
I did a similar(not as big) I welded the blow out patch on,then did the cracks with Harris 45 safety silv! It actually has held up for a few years now! Thank you for the video.
I ran a 49' Adams grader on 7 mile private road for a few years. Much like this Cat , it had crash boxes . You learn quickly how to grip the controls so the dont bite you . Great repair you two!
Looks pretty darn good to me, most welds under cars dont look that good without the oil to contend with, I could have done with an extra pair of arms for some of the stuff I have done in the past, I cant really do the under vehicles stuff anymore and I don't really miss it to be honest. Thankyou for sharing, this is fantastic work
Great job Isaac (and son!), that was a rough spot for sure. I do all my maintenence on my equipment outside (I don't have a garage) cardboard is a HUGE help. If you can manage to get your hands on a mattress box your in..... and I realize it can catch on fire, but it has never been an issue for me. I've had many charred spots, but never a fire. Especially good in the winter (I'm in the northeast), keeps you of the snow and ice, plus you can find nuts and bolts you drop super easy! Thanks for the video, great job!
Be a welder they said. Repair mobile equipment they said. It will be fun they said.I admire your discipline in keeping your tacks small and maintaining temperature control. I tend to always push the limits and generally end up paying the price in rework.
Isaac, that repair looks super, very interesting welding of cast. I assume the needle scaler helps reduce the stress that is created in the weld. As always I enjoy your repair videos and you sure have a super talent completing these jobs. Thanks for sharing.
I do a lot of work at a yard I have my sealand continer shop. Stone yard. Heavy cardboard. Works great, ya can slid on it and if you're just careful with the cutting, it works. And it doesn't burn that easily.
I like the way you yell at your equipment 😂I do the same thing when I’m under a machine and it doesn’t want to cooperate 😎🤙🏼. Great to see your son helping out 💯💪🏽
