Making & Testing HEAVY DUTY Tool Extension for BIG D11 Hub! | Shop Made Tools

Published 2024-08-09
We've got a monster of a job on our hands today! A massive D11 bulldozer final drive hub is in the workshop, and it needs some repairs and upgrades. To machine the problem area we’re making a custom heavy duty tool holder extension from scratch. Watch as we transform a thick slab of steel into a precision machining tool. But before we get there, we've got to get our big lathe ready for this huge hub by setting up the face plate and removing the gap out of the bed. From gas cutting and milling to precision machining, this episode is packed with action. You won't want to miss it!

In this video we are using:
- Unimig CG-30 straight line gas cutter
- Hafco BM-63VE Milling machine

  • I still love that number-eight-wire ingenuity/attitude of "to get this job done right, we need a custom tool so let's go and make one, then get the job done right"

  • @davidlasoff8261
    Really a great touch leaving so much material on the special tool to prevent vibration. Once again, Kurtiss shows us just how skilled and smart he is...great video, Karen!
  • @typrus6377
    I've said it before, I'll say it again- I wish we had folks like you near us! Not just the physical machine capacity, but the attention to detail, pride in and of work, creativity, and care for your customers. We have so much up here that we just have to order ReMan/ReCon or new because either noone is willing/able to do the work, or they do such dodgy work that you end up with more headache than you started. We just had to buy a ReMan for a D7RII that noone was willing to fix the flanges on. Despite us being able to get the Salvage specs from Cat. You are both a credit to the field, and have my admiration.
  • @barillius
    Haven't seen the vid today, but I wanted to get a question in for Karen. Karen, which is longer, the time Kurtis takes to do these projects or the time you spend editting them? I ask this because as much as we appreciate Kurtis' knowledge, expertise and ability with the tools of the trade we cannot forget that your knowledge, expertise and abililty as a videographer and editor are just as amazing. Thank you, Karen, for what you're doing with Kurtis' work. You make it so much easier for us mere mortals to understand and visualize exactly what the maestro is doing. So, Thank You from the bottom of our collective hearts. You're one of the best!
  • @Horus9339
    Kurtis proving he is the Hub of the business. Great work Karen, you really do a stella job editing and producing these videos. Okay guys, have a great weekend.
  • @markspeller5722
    It's great see two people right on the ball. Kurtis with his machinery/engineering and tool knowledge, Karen with her video work and incredible patience 😀👍.
  • @jackreed3445
    That is some hunk of steel out there with the forklift extensions leaning against it. I'm sure I'm not the only person interested in that job. A very cool shop tool. Pretty soon you will need a pallet sized rack space to hold all your shop made tooling. I like the way you figure out what is needed and the fact that you don't have to but expensive "stuff" you can make on your own. Have a great weekend, jack
  • @ColinMcEvoy
    My simple mind cant comprehend Lathes big and strong enough to handle D11 Hubs.. Always awesome watching your videos. Cheers from West Coast USA
  • @paulhammond7489
    The 7-point locking of the tool holder extension using all 90 degrees of the normal post was superb, that combined with the shape of the custom holder gave it the rigidity needed on an interrupted cut... 10/10.... It's gonna look real cool when it gets its planed finish.
  • @smarthome2660
    Hey Kurtis, my biggest repair was a 72" x 84" x 12" press plate bore out, sleeve and re-bore 4 - 9" holes with counterbore for seals. Over 10 tons on an old Cincinnati Gilbert Boring Mill. Tolerance was 0.0002" on location and size. Those old machines seem to last forever when you keep them clean, oiled and serviced. My main job there was making press plates and hydraulic manifolds size = 16" x 18" x 16" with approx. 48 holes. Precision sizes and depths to control flow of hydro oil to all machine parts. I also worked on weldments on a 120' X, & 10' Y travel floor mill. That's 120 feet of travel while you ride on the machine head, awesome. BTW I was impressed by the quality of the surface on that tool you torched out. It was like machined, then surface ground smooth.
  • @2barrell
    I love it when you fast foreward Kurtis moving aroung the mill. Now all it needs is Yackety Sax playing, and Karen patting him on the top of his head as she chases him around.
  • I really wish Curtis was one of my teachers, you just know he would be really good. He would teach you the reasons why you do things that way.
  • @williamcox8208
    I have been watching these CEE videos for over 3 years, it still amazes me that Kurtis has developed that kind of skill and expertise. I sold Komatsu, Ingersoll Rand products for 35 years and I ran across no one that could do the kind of machining that you do on a daily basis. Although our market does not support a large population of mining size machines, there would certainly be a demand for services like yours. Thanks!
  • @UncleManuel
    I can't get over HOW FRIGGIN CLEAN those torch cuts are! This is very impressive! 😲😲😲
  • "What a beast of a machine!", now that's a title to aspire to having! I must say that quickie cutter was mesmerising. Another great job in the CEE books. Thank you K, K & H.👍
  • @Davew-d8t
    I've been a machinist for 35 years and I've learned something new ever time I watch these
  • The shop made tools segments are always some of my favorites!
  • @paulcohen1555
    The surface finish of the acetylene cutter is AMAZING!
