Bobcat S-150 Loader arm repairs 

You can use a center punch to out line your circle with a series of punches. Won't disappear from the torch. I do this when blacksmithing.

You can tell how much experience a guy has by the size of his umbrella. I enjoyed watching as always.

Sometimes retrofitting a wearable item into an already roached out piece of equipment is much harder than working on newer equipment. Kudos to Isaac and his son on this job.

You seem to be very patient with your son. I can tell he has great respect for you. You were clearly a good father and your wife was clearly a good mother. That isn't easy when you own your own business. Also wanted to say I love your videos ❤

My father was a machinist, everything had to be precise. His buddy who worked same place for years was a truck driver, welder, fabricator. Was fun to sit back and watch them build stuff together. Dad's buddy would tell him aw don't worry about it get it close and it'll get used to it lol. Give anything to be able to go back even if only for a short time. Glad you and your son seem to work well together and your passing along your knowledge to him. Will help him out immensely.

They've got you hidden out back so customers can't see the old worn out machines being fixed up 😊

Oh my, I finally figured out what I'm doing wrong! I have been eye-ballling things with my bad eye! 16:30. 🥴

Good job as usual. I caught mine before the tapered holes were damaged. It's good to see it done once in case I ever need to do the same. Thanks guys.

Love seeing a son follow in his fathers footsteps

my grandfather use to center punch a series of marks at the clock points. Even if the marker burned off, the punch marks were seeable.

" Where's the hammer " "Which hammer ? " " ANY HAMMER !!!!!! " 😂

Man I’m starting to get into some of this machinery repair and not going to lie, pretty intimidating. You wouldn’t think so since I used to work for bobcat and CNH ect ect. Built alot of huge equipment but repair is much different. Thanks for all your effort I know the videos ain’t easy to make.

IC your hands are as steady and precise as many surgeons I’ve watched on RU-vid, you are credit to your trade!

True JourneyMen only come from Father/Son Teams :) Love your work and I truly admire how you are teaching your art to your Son. God Bless and teach him well. This is the kind of training schools only wish they could do.

Isaac, you’re a surgeon with the torch. Very informative, and the line borer earns it’s keep, once again. 👍🏻

Puts ease to my mind knowing not everything has to be spot on perfect. I’m a pipe fitter by trade and always try to go for near perfect but in equipment repairs it’s not always that way haha. Awesome work

Great to see Jr. in a video again!

Man your a magician with that torch. Excellent repair as usual. Perfect to watch with my morning coffee. Thanks for the videos from Australia

I have seen and done a lot of torch cutting but I have yet to be able to perform like that. So glad your son is with you to absorb the skills of a master. Great work as usual.

“ eye balled it using my good eye “ ! Gotta love Isaac classic humour.

You've mentioned line boring a number of times in your videos but I don't know if I've ever seen you doing it before. Interesting procedure, thanks for sharing.

Everything has a bit of tolerance for adjustment plus nothing a ten pound sledge hammer can't get precise even with your one good eye. IC jr is really coming along, I can see the confidence he has doing more. Give him some time with the gas ax and plasma cutter, I see his welding has improved in previous videos. As usual great video and very informative ❤

Surgeon with the cutting torch, great skill set! Your son has the opportunity to gain invaluable practical experience from his Dad, lucky guy!

Look up “Presto” jumbo correction pen. It’s like a ball point white out pen. Works great for marking steel and will hold up to the high temps of a torch!

"My good eye" and "hope you learned what not to do" my man has jokes 😂. One of the best repairmen/welders I've seen in my 30 years of welding!! Awesome job, thanks for sharing. Stay safe, and God bless

Thank you for these videos. I have learned how to torch like a pro from watching you work. I put my skills to the test the other day and my torch cutting project was a success.

Worked at a Bobcat dealership for 2 years. They had a tapered reamer to fix the wallowed out tapper. Maybe these were past repair.

That depth of cut on the last arm would have made Kurtis jealous. 👍 Keep up the good work and Be Safe.

I just watched a video that was all about the history of the Bobcat. It was invented by two brothers who were blacksmiths and welders. You should check that out!!!

That looked like a easy one compared to the backhoe frame that was crazy. Good Job.

Probably the most precision on that old girl. When things are that worn, you just have to do the best you can and you did very well.

Another excellent job out in the field with a hurry up customer. Well done Isaac & Son!

You rescued that Bobcat! And made your son very happy since he is working in the field with you. Good result well within tolerance.

Thanks for the video Issac great job on the Bobcat your Son is learning the Craft from a Great teacher. Take care of yourself and family and be Blessed ❤️❤️👍.

I really like your content. It is real world stuff.

It’s GOOD to NOT hear you cursing, family oriented…

Thanks for another visit to Isaac's Engineering Machining Welding and Education Services.

Excellent! I’ve wondered how the line boring is done. You presented a clear picture. Thanks.

No sloppy holes............Tight is right. Best of Luck.........................

Thank you Isaac and son. You two make the miserable jobs look easy.😊😊

As usual great videos Glad to see your son help you on this one Thanks men it was awesome

I had to laugh when you said you didn't want to bore us with the second one....but you were boring; the machine that is 🤣. I see your son is coming along in his confidence of what to do and what is needed, keep up the great job mentoring and teaching him. Looking forward to seeing what you have up next.

Nice example, you had me worried about the alignment but I shouldn't have doubted you. Hahahaha, thanks for the video!

I injoy watching your show. I was a finish grinder and I was working with tense of thousands but I enjoy watching do line boring

Another interesting repair to get yet another machine back to work again.

I don't have your skill with a torch. I would use a magnet drill press with Annular bits. You do a great job fixing equipment that has been thrashed. Always great to see your son learning.

I bet Kurtis watched this with great interest.

Great real world example of how to get it done, Thanks for the video!

You did a great job as always.. That great fix you did on that machine. Very humble guy.

After watching many of your repairs, I have improved my ability to tackle more domestic repairs. Thank you Sir for sharing you knowledge and please continue to do so.

Patience only asking directions ..your the teacher lucky to have you

Very interesting, great job you two.

Hi Isaac and Nick, nice fix, good to see how a job like this is done. Thanks for another interesting video guys, stay safe, best wishe's to you all, Stuart Uk. ,

I like your whisper into the camera " I don't want it that tight" the truth when you need to think on your feet.

"It'll live to fight another day." ✝️🇺🇲💪

It’s never “Boring” around here.

*I C Weld* Bravo well done, thank-you sir for taking the time to bring us along. GOD Bless.

Freezing your bushings helps alot

Nice work. Watched a video on the history of the Bobcat skidsteer. Invented by a guy with only a 6th grade education.

I think it's great that you work with your son. I used to help my father doing electrician sidework on the weekends, and I learned a lot from it, particularly that I did not want to pursue a career as an electrician! seriously though, there is no educational substitute for shadowing a professional on the job.

You make CEE Engineering with his shop boring bars look like he’s working in a palace. Great on-site work.

That boring rig is slick.

You sure have picked a good grade of carbide for the job! Really like that clamp on tool setter as well. It looks really well thought out in design.

You do you. The proof of your method lives in the future, I think. 😊Steve

You never cease to amaze me. You are the torch surgeon!

Awesome job Isaac. Keep the videos coming. Very educational my friend.

You’re a great father and teacher.

Abom79 would be impressed with chips. Nice work as always. Your torch skills are second to none !!!!

As usual you make it look so easy. Having the line boring rig and knowing how to use it is the key. When we did pivots last on my brothers bobcat a gas ax is all we had and the finished job looked terrible even after the grinding. All your jobs are done in such a well thought out professional manner. Line boring is one of those mystery jobs no one seems to know about. I've never seen a line boring rig for sale used. Are they all passed down from father to son? LOL. Thank you for documenting the process and making it look so straight forward.

You are the number 1 master of your craft. Love the videos

Good job, steadier hand than I have with a torch. If I had that job, I probably would have gotten my big magnetic drill out. Put a small bit in that fit that bushing hole to find center.. Then back the bit out, without moving drill and put in a 1.25 annular cutter bit. Then drill the hole out. Just need plenty of coolant and should not be to bad.

Cool new fire blanket!

Another awesome repair, step by step . I really appreciate it . I need to do this exact repair on my front loader

Top notch, I would have used a mag drill to get the line boring machine in, only because my torch work isn’t anywhere near your level.

Yall do great work!! I love watching a true tradesman

Another work of excellence out the door/field !

Nice to see this video, so as to know what to look for in a repair. Thanks

Coffees on brother ,,here we go!!1;-)!!!

Isaac, great looking repair and as always top shelf video for us to learn. Thanks for sharing your insight and skill sets.

boring bars always look like high tech repair but guess they are getting to be old school now. thks for sharing.

I enjoy watching your videos

Hey Issac, when I replaced the bushings and pins on my 79 Bobcat 530 the bushing were pressed in, not welded. Easier but still a pain! After digging out a ton of grease I split the bush with the torch to get it out. "Pressing" the new bushings in involved big hammers!:( The bushings were so bad that it wore into the arms on both sides. I cleaned them up with a grinder and was then able to put a big washer ( about 1/8") on both sides which filled the gap nicely!:) Works great! Bobcat wanted over $700 for the bushings and pins but I was able to find them on line for $250. Thanks for the great videos!

Nice work as usual. A lot of experience being displayed. Thanks for sharing.

Another fine job Issac

Don't let anyone tell you your "eyecrometer" isn't good enough. Great job!

Another great video, Isaac! Pedagogic and enjoyable. Thanks! (I do not do much welding here, but I did get me one of those cool welding caps...!!!)

Excellent work!! nice to see a clean cut professional looking young man.

Great job! that old Bobcat lives to earn another buck for the owners. Cheers!

“I won’t bore you with that”.....I get it...I won’t “bore” you wile line boring....🤣

Great work,always impressed with your torch work. Thanks for sharing Safe travels. Looking forward to your next video Thanks guys

Great job as always. Your son looks professional like his father. Sometimes when I am going to cut something out I will center punch the line so I do not lose it.

Excellent repair as always! Only two minutes in, I noticed the area of repair was less than waist high. The loader arms could have easily been raised and blocked at a more convenient and comfortable work height that would have also made the repair go much faster. This is almost always the case, but seldom is this realized in the industry. In addition, the wear and tear on the body will show up later in life, but sooner than it should. Trust me. I know from experience .... unfortunately. Regards.

I won't bore you with that, no pun intended.

You job is very similar to that of a dentist, save for size. Brilliant job, Doctor!

Have the same machine and just bought a tapered bushing repair kit for that job, then bought a Hougan annular cutter and adapter for a mag drill to cut those bores instead of dealing with that whole torch and line boring setup to insert the bushings

Don’t forget to oil that impact.😊. Steve

Thanks for taking Us along!!👍👍

An interesting task that one. Great work with the torch as usual.

Very nice quality work as alway's they should be very pleased !!! Top shelf work all the way !! 👍👍

Beautiful!
