Machining a BIG Cylinder Rod for Mining Excavator | Hitachi EX1900 Boom Lift

We need the BIG Lathe for this machining job! We are making a new cylinder rod for a Hitachi EX1900 Mining Excavator boom lift cylinder. The chrome rod is worn out, it has rust spots and fatigue fractures, so we are going to make a new cylinder rod. This shows the step by step process of removing the eye off the old rod, machining up a new rod and welding the eye onto the rod. First step is machining out the weld joint that holds the eye onto the old rod. Once we remove the eye off the rod we also press out the damaged bushing in our hydraulic press. We then start machining up the new cylinder rod by rough turning before finish machining the end for the piston and nut. We cut a 4mm thread pitch external thread for the nut before flipping the rod to machine the other end. We machine and drill a hole before fitting and stick welding the new rod eye in position. The eye is welded on using metal cored wire before press fitting the new bronze bushing. We finish the job by cleaning, wrapping and strapping the new rod and send it on it’s way to the customer.

In this video we are using:
- Shenyang CW6280B Centre Lathe
- MetalMaster HPM-150T Hydraulic Press
- WIA 500i Weldmatic welder

This was a big job, there was a lot of machining and a lot of editing for this video so we hope you like it! Let us know in the comments what part you liked the best...we are loving the slowmo with the button insert 😍

The best part of this whole channel, aside from Homie and Giggles, is that we're watching a master of their craft who can achieve and expects near perfection from himself - Every. Damn. Time. It's more than a little bit humbling.

"It's 3.7m long, or 12 banana leaves" Curtis putting things in an understandable perspective

[Biffo]

Aside from the skilled engineering in these videos can we take a moment to appreciate the level of expertise in the camera work, editing and professional level of presentation shown in every video. This the level ALL YouTubers should strive to achieve. Thank you for all your efforts. This grumpy old fella appreciates the efforts you put in.

0:49 This is one of my favorite things about this channel. The little nuggets of information about just how and WHY these parts are used the way they are are solid gold.

[JanMichaelRossi]

I have never machined anything in my life. I don't even know how I stumbled upon your channel. I am just fascinated by the sheer level mastery over one's craft exhibited in these videos. Your skill and expertise are inspiring to me.

[davehine]

Karen, Your camera work is fantastic but the split screen is above and beyond. Thank you for the hours I know this takes! Oh and Kurtis, you're pretty good at what you do too.🙂

[billjamison]

It's people like you that keep the world moving! Hard work and the personal satisfaction of a job well done. Fantastic video as usual!

[mikeyliah]

It’s a tossup as to what’s the most impressive:
Shop’s strategic growth and financial planning acuity; Kurtis’ engineering, machining, welding skills; Karen’s impeccable production. If there are awards for YouTube production, Karen should get one. Thanks to you both! I so look forward to Fridays. Michael from Texas, USA.

I am more convinced than ever that Kurtis' Superpower is being able to see the centre of gravity of anything he is going to raise off the ground. I was wondering about that tool post, not up to CEE spec. Great work on the filming and editing Giggler. Thank you Kurtis, Giggler, and Homey!

[aaronpreston]

I love the split screen shot of you at the controls and the view of the tool cutting. I really puts into perspective the hand-eye coordination you need to operate.

Fantastic videos as always. Have a great weekend you three!

The top quality, and pride you take in every job inspires me to do the same in my career. Most of the crew in my shop couldn’t care less about their work, and management is too afraid to crack down on them due to a number of different reasons. It’s tough to keep my head up some days, but seeing people around the world who care and are a great learning resource helps tremendously.

Jim Sim... as tradesman joinery cabinet maker old school .. it is a pleasure to watch someone who knows what he is doing using good large equipment with pride in the result you deserve success in your business good video thanks my brother a ships 1st engineer is also impressed

[kevina.]

Ah yes nothing like a BIG ROD first thing in the morning.

[rolanddansereau]

As always, your videos are so interesting and informative. You seem to make things with so much ease and accuracy. The camera close up work is amazingly so vivid and clear. Awesome work Karen. Love watching both of you work, time flies by when I watch your videos. Keep up the great work both of you. PS: I love watching Homie run around with the camera mounted on his back harness.

[scottmclennan]

Watching that threading insert go to work is terrific. Amazing to think of a huge piece of metal like that being turned into a big bolt.

[brianperkins]

I have to say this is one of my favorite channels after a long day of work. Your expertise as a team, between the machining and the filming and editing side, shows a true workmanship that is a dying trait in todays society. I can honestly say i look forward to every video you release and on many occasions go back and watch previous videos multiple times. The humor in your videos as well as the outtakes crack me up and just lets everyone know your real people. Homeless is another reason to come back every time a video drops. But, i have to say the biggest thing i appreciate about you and your channel is your ability to keep your private life and business life separate. i think to many people put to much of themselves out there on the web just to gain a few more subs, likes and views but is it worth it. I like the fact that you two keep your personal life off the camera and leave people guessing. Dont ever let anyone take that from you or convince you otherwise unless its your choice.

[DonLuc]

I am always amazed at the level of creativity shown in the vodeography and editing, right on par with top studios anywhere. Yeah, Kurtis does the machining, but, the videographer brings it to life. Always perfect lighting, focus and emphasis on the action. Thanks to both.

[vincenthumphreys]

Thanks for explaining the reasons for the cylinders orientation civil/mining!

I'm a retired heavy-duty / equipment mechanic. I stumbled upon this channel as well and been fascinated! About the quality of his work. The way he takes care of his shop, his equipment, attention to detail and concern with the customer's expense. The fact that he does it all with no other shop Personnel was amazing. He has his safety coordinator, his dog in the shop plus his supervisorial staff, the birds. They do a great job!
