Making NEW Pins for Earthmoving Machinery | Machining & Welding

Published 2023-02-09
These pins are worn out so we are making new replacement pins! We’ve got 2 big bucket pins from a Hitachi ZX670 Excavator and 2 pins from the ripper bed frame off a D9T Bulldozer. We show the step by step process of making the new pins. We start with machining the plates off the old pins before machining up the new pins using induction hardened chrome rod. The D9 dozer pins also need deep hold drilling and tapping for the grease holes before using the milling machine to drill a through hole for the grease channel. We finish up the job by welding the plates onto the new pins.

In this video we are using:
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine
- WIA 500i Weldmatic welder

  • Best part of the editing is she knows when to speed up certain parts that are highly repetitious and we've already seen. When a new process comes up we haven't seen she slows it back to real time. That really helps it from becoming a 2 hour video without missing anything. That only comes from experience. And Curtis is his normal awesome self.

    Got to say. Never miss CEE drops. After watching all the outtakes….Kurtis is a true master of his trade/craft. Karen via her filming and editing makes Makes Kurtis appear that all his words flow and make perfect sense. ….. The outtakes say otherwise 🤣🤣🤣 Homey seals the deal…you guys deserve every success 👏🏻👏🏻💪🏻💪🏻🙏🏻🙏🏻🇦🇺🇦🇺 Have an awesome weekend 🍻🍻🍻

    What I appreciate about the bloopers at the end is how often you smile/laugh. Being able to do that throughout your day is key to long-life and happiness. Keep it up you two!
  • You are so delicate and mindfull with your equipment, I've seen other "fabricators" throw their tools and being the "rough" guy.
  • @DonDegidio
    Hi Kurtis and Karen, Was all set to hit the sack and was notified your video was uploaded. Well worth the lost sleep. You both stay safe.
  • Thank you for showing us where these parts go and work on the machines. Elevates the context to the next level !!
  • There’s your “cutting edge engineering” right there in those shop-made “V” blocks. Excellent example where a little thinking shortens the time for a job and saves the customer $$. 👍
  • @lilgheorg6475
    I am from Moldova,I like your video's,you are very good in metal processing-one day I will be as good in my field as you are in yours.
  • What I find fascinating about the work you do is the crazy mix of "I'll do it by eyecrometer" and "Better measure with our most precise measurement instrument"-type work you do, and how your approaches differ there. It takes a skilled craftsman to do a job only as precise as necessary, and still within spec. And your wife is doing just as great of a job with the editing, she makes time just fly by! And I'll never get tired of saying it, not having mouse squeaks during timelapses is highly appreciated, and something that just elevates this to another level!

    I've never touched a lathe in my life. No idea how to weld. Everything about this channel is outside my knowledge set. But every single video is a must watch for me. It's great to watch a master of a craft at work. I truly appreciate the tone of the channel, and the wholesome honesty they work together to produce in every episode. My sincere thanks for the great entertainment
  • @joerainey2619
    There is something so satisfying about knocking out jobs like this… not building an entire village, not worrying about saving the whole world, but just fixing things… something with a start, middle, and finish that’s all within reach within a day or two. I’m so jealous.
  • @Anthonyecc
    I don't know what it is about your videos but I always look forward to Friday when the new one drops. Top work keeping me distracted for 40 mins !
  • @tinman7551
    Here’s to everyone enjoying the master craftsman Karl and his intrepid producer/director Karen tonight {in the USA}. We’re living our best life and that’s for sure. Thank you guys for another incredible video and give my love to homie ❤😊😍
  • I will probably never step foot in a machine shop or ever find myself in need of a skilled machine operator such as Kurtis, but it is still so satisfying to watch a job start to finish.
  • @chadkennedy529
    Coming from somebody that grew up welding and lineboring equipment for decades, Curtis is a wildly intelligent guy. Everything he's doing would take your average welder/ machinist 3x longer to do any of this.
  • Karen's camera work and editing are so smooth and show the job in the most interesting and entertaining ways. Professional, accurate and fun to watch with always little artistic nuances that add a lot to how the job is presented to us. Shows the job as its done in its best light.
  • This morning I feel even slower than Captain Slow. I just realized that there is more than one interpretation of "Let's face it" because of the lathe turning meaning as well as the more general one. Oh well. Never too late to learn, I guess. Excellent work on the video and the metal work, as usual. Have a very good weekend, everyone.

    Once again absolutely outstsandin kurtis . You and Karen the best.
