Making a 100T Heavy Duty Mining Jack Cylinder Rod | Machining & Threading

Published 2023-08-04
This video is a job we did to make a new cylinder rod for a 100 Tonne Edmo heavy duty hydraulic jack that is used to lift mining trucks and excavators. The rod has scratches and dents in the chrome and the top of the cylinder rod is damaged. This shows the step by step process to make the new cylinder rod including machining and thread cutting. To start, we remove the piston off the rod and that will be used to test the thread on the new rod. We machine up the new cylinder rod using a 6” inch diameter induction hardened chrome bar. We need to machine both ends of the cylinder rod, the first end we drill and bore the hole to suit the load cap. Then we machine the other end of the rod by machining through the induction hardened chrome layer before turning down the OD and cutting the 8tpi external thread for the piston. We finish the job by installing the piston before drilling and tapping a hole for a grub screw to lock the piston on the cylinder rod.

In this video we are using:
- Hafco TM-26120G Centre Lathe
- MetalMaster HPM-150T Hydraulic Press

    CEE has to be one of the most productive and successful 2 person work company on earth. These videos are so well done!
  • @jogden6632
    I'd hardly use the word "cheap" to describe your craftsmanship, Curtis. "More affordable" may be a better way to describe it. You guys are extremely valuable in your workmanship all the way to how you make your parts, handle your shop and even make the videos! Glad to have you guys back this week!
  • Can't be said enough that Karen could have a career as a video editor/producer. Plenty of other channels DREAM of having such well shot and edited content.
  • @w.o.o.d.y
    Kurtis, you guys don't ever do work that's cheap. You offer exceptional quality engineering goods and solutions that are more cost effective for your clients. A very niche enterprise conducted and orchestrated by very respected people. Hats off to you guys once again !!
  • @peterlee3996
    I am a retired electronic and computer engineer from Perth Australia. Although your work has little to do with mine I find your precision and quality of your work excellent for some one as young as you. Diligence is the word. Well done to both of you. Your wife's camera work rivals the BBC. Keep it up, I always look forward to it. Pete
  • @zestoslife
    Blows my mind every time I see threads done on the lathe. Intellectually I understand it is just gears and cogs moving all together to make a repeatable pattern, but there is something magically about this process and how it works.
  • @joelbrown3479
    As a sidetrack... MATTY's WORKSHOP is on PAUSE till he recovers from a medical issue. He may pivot, and create videos of his recovery IF there's an interest. Nothing but the BEST for our friends from down under. Bronx Love guyz 😎
  • Hey Kurtis, great to see you both back - many thanks to both yourself and Karen for all the effort you both go to to get these videos out. No idea why, but watching you work your ass off is a real pleasure (and really interesting to see you work on all the different projects and how you complete them) - I look forward to the next video every Friday.
  • @OmarMekkawy
    And finally we got our entertainment for today 😂😂
  • @OwenFromOhio
    Dear Kurtis, Karen, and Homie I happened on to your channel a couple of months ago and have binge-watched nearly every video. Being an old man from rust belt Ohio USA I've always had a soft spot for tool and die folks. Your skills are only surpassed by your wonderful wife and dog! Thank you keep up the great work!!
  • @Jasmate
    This is great content. No gimmicky music or effects and makes you feel like you're there. Well done guys! Appreciate it.
  • @woobykal68
    I find it amazing that kurtus can make a brand new rod that is much tougher as apposed to just getting it rechomed.
  • @gav2759
    Kookaburra sits on the old chain link fence....wait, I feel a song coming on. Great stuff, thanks for posting.
  • @danielpullum1907
    Hello Down Under, Karen do you ever get tired of watching Kurtis work his magic? Well, I don't. !!!!!! This the second time I've watched this particular vid. I love them all. I've commented before about the rigidity of your equipment and how easy you make it look to cut threads. Beautiful work.
  • @robertwagner8596
    it wont be long and your going to have one of those birds sitting on your shoulder while your running the lathe....how cool is that gonna be,well done and again,thanks for sharing!
  • @hdfanboy
    No CEE and no Matty's Workshop last week. I thought the world was ending so I'm glad to see you back.
  • @bobdavis5216
    Watching Kurtis double check his settings for the threading .. reminds me of doing the same thing with fuel transportation when loading/unloading. Cuts down on the mistakes.
  • @joeybleu66
    i am a retired person in the USA. I missed you folks. Glad you both had a great time taking a break.
  • @Horus9339
    I haven't slept in over a week, no machining, no squeaky toys, no George and friends, missed the giggles, a lack of 'Fuck off train', or 'Is my hat straight?'. It's so good to be back to normal proceedings. Thanks guys, have a great weekend.
