Can We SAVE This $20K Cylinder Rod!? | Gouging SEIZED Nut

Published 2023-06-23
The nut has seized and locked onto this $20K hydraulic cylinder rod! We’re going to use carbon air arc gouging to try and remove the nut and save the cylinder rod. This is a bucket cylinder rod off a Hitachi EX1200 mining excavator. In this video we show the step by step process how to gouge off the seized nut using carbon air arc gouging. Stay tuned for the next video where we need to machine up a new nut and we will be machining new threads onto the cylinder rod.

In this video we are using:
- Lincoln Electric DC-400 Welder
- Hafco TM-26120G Lathe

  • Hope everyone had a good week and enjoys todays video! Let us know in the comments how you think this went 🤔 P.s. Gouging is LOUD so the audio when gouging has been reduced by 70% 😅👍 Subscribe and hit the bell icon to turn on notifications so you don't miss our weekly uploads. 👇 🤳 📲Follow us online here: linktr.ee/CEEAUS 🛍Official CEE Merch shop: www.ceeshop.com.au/ 🎉Get Early Access & Ad Free videos in our Patreon community: www.patreon.com/cuttingedgeengineering
  • Thank you for the extended explanation of how air arc gouging works! Showing where the air comes out completed it for me!
  • @alfonsoalonzo
    nerves of steel to handle 20k+ worth of possible collateral damage always love to see a customer agree to a repair
  • My first thought was "he's gonna gouge up the threads! Not like he has a lathe big enough to fix that!" You did not disappoint. Great video.
  • @jrussell1074
    I've worked on high value parts for many years. No mater how skilled, there is always the possibility of something going wrong. It's nerve racking. Sometimes the customer will actually appreciate what you go through and what you saved them. It takes a lot of skill and experience to have jobs like this come out well.
  • Kurtis, any time you feel like giving us an extended explanation like you did for air-arc, go for it. This video was the best use of my learning time for a week.
  • Love the short explanations in between, makes it more interesting and a lot easier to understand why he is doing what he is doing! Thanks for the great vids!
  • @SilverCymbal
    I thought I was clever using a Dremel doing this on a tiny scale on home projects! This is beyond amazing on a HUGE JOB with such skill!
  • @crazedboy805
    This just randomly popped up for me. This has got to be one of the coolest machining videos I have ever seen! Thanks for explaining everything! Cheers!
  • @rosbifke
    I think the best way to describe that air arc gouger is “a reverse stick welder”.
  • Karen, I laughed when Homey lifted up the suction cap lever after seeing you push it down - pure gold!🤣🤣🤣🤣🤣
  • @erck815
    Ive been doing custom metal fabrication for over 12 years. I work for a well know global machine manufacturer. This is truly impressive and educational. I could ask a million questions man. Keep up the great work.
  • @brianhind6149
    Curtis: I laughed at several of the things you did. Understand that I laughed because I learned how some of these seemingly impossible tasks to me, looked so obvious when you did them. I have learned the names of many tools, & observed how things were repaired via procedures that I would never have thought of. Wow! Curtis, you are a warehouse of knowledge in your trade, & my hat is off to you. It is a pleasure to watch you start to work, AFTER you have considered the best avenues. Great Stuff Curtis !
  • @rohanhart5610
    The skills that Curtis has to make this possible is absolutely mind blowing
  • @-ScottyT-
    Your ability to fully understand the entire situation and provide the most cost effective solution must provide significant value to your customers. I am truly amazed at how much goes into what you do.
  • @stick4250
    The pup lifting up the latch for the suction toy at the end lol.
  • I'm from London and I visited Australia in 2016, touring it extensively for a month. I must say that this fella has the best old cockney accent I've heard in years. Great to know it persists in our old colonies. Warms the cockles, it does.
  • @haydenc2742
    Kurtis goes straight for the "It can't be stuck if it's a liquid" mode :D! Love it! Keep em coming!!!!
  • @pear7777
    May I thank Kurtis for the extensive explanation about the process.I know you're not a man of many words, but it is massively appreciated. His craftsmanship seems second to none, seeing this job was absolutely rad. As a problem-solver myself, I love to see this process. And as always: meticulously filmed by Karen, so we see the complete process. ♥️🤟🇳🇱
  • I think they had as much fun making this as I did watching it. Pro machinist and craftsman. Thank you!
