    Thanks for the video Adam. I have owned a 12X36 inch lathe for 40 odd years and while I have knocked out many jobs for the farm in that time I never really knew how to use it properly. Thanks to you, Keith Rucker and Keith Fenner I have learnt so much. It has been like going to trade school for this 76 year old. I now know a lot more than I did 10 years ago, but I still have a long way to go. Many thanks to you and your colleagues for all the tuition. It has been a very interesting journey. Kindest regards from Australia to you all.

      Same sort of thing except for a young guy. I fixed things and made pieces with a lathe for farm type stuff since I was a little kid, Adam and Keith Fenner taught me all the knowledge which I could immediately put to use since I already was familiar with the machines. Now I am doing much fancier and better repairs and have machines of my own!

      I screwed up the dis-assembly of a spring-loaded retraction mechanism on a sun awning and the runaway rotation stripped the teeth off of the pawl bevel gear. I mounted the gear in the chuck of my recently purchased vintage Craftsman 101/Atlas 618, turned the threading tool 90 degrees, set the compound and re-cut all of the teeth with many passes. The gods of Machinery’s Handbook smiled on me, and the 60-tooth count on the gear exactly matched the number of index holes on the main shaft gear aiding in the process..
      The cost of the lathe plus shipping was less that the price of a new awning. The first of many repairs around the house that would not have been possible without the lathe.

    Just watched this video, and I can totally relate to a one stop shop. I am 70 years old, got a wed/fab/machine shop in the country. Seems like people from all surrounding counties come here to get things repaired. They have learned to call, bring it, leave it, till I call. Most of them have learned, that if it is fixable, I will and they leave me alone to do that. Really like watching your videos. Im from Mt. Sterling Ky. Had welding company, Dale Welding Works LLC, until I lost my son 4 years ago, sold my trucks and stay in the shop now. If I was closer to Florida, I would visit. You and I could have long conversations.

    I might tick some people off but damn it folks clean your parts that you bring to guys like Adam to be repaired. They don't need to contend with your dirt before they can start the repair process. Yes I know it takes time, but would you rather pay machine shop rates or an employee that you are probably paying half as much or less to do the job!

    When I worked with gears, I was taught to never trust the bore to indicate but rather indicated the teeth with a pin that makes contact close to the diameteral pitch and indicate that in. Maybe I was doing it wrong. Love the videos and new shop progress!!!

    Ever since I was a kid I loved to watch welding and machining......dunno why I didn't go and apprentice somewhere. My Dad was good at both and was a farrier as well. I enjoyed every kind of welding there was but in particular I loved watching him weld with a forge. A friend of mine used to machine parts for my Husqvarna dirt bike when I could not get parts in time for a race. We traded work for work and his machining fit better than the original.......he was an Ace with his lathe. I'm an old guy now and I enjoy watching your uploads just as much.....thanks!

  • @paulhunt598
    @paulhunt598 2 роки тому +1

    I watched this repair series out of order, so I got to see the issues Adam had with fitting the repaired bull gear to the new shaft before I watched this video. I enjoyed participating in the "better methods" discussion after the final video. All of this is very interesting to me Adam had challenges and methods to address them from the beginning of the repair. Adam may have been more successful employing different methods, but he knows his shop limitations and assets well. He has done similar successful approaches and that likely affected his approach on this repair. I spent a career doing repair work. I didn't have a UA-cam community to critique my approach. I enjoy the UA-cam community when we add helpful and constructive comments. I am here to learn and Adam is likely learning too.
    This series is the content that brought me to the channel. I need Adam's machining skills and he remains the best instructor that I have found for this content. I never intend to grow my machining skills beyond repair work. I worked maintenance in a high production shop for my career. I have had my fill of the high production environment. My hobby life is having the capacity to make and do what I need and want and to learn and refine skills that I lack. I learned a lot of skill practices and approach from this repair job. I will employ them when need arises.
    I especially liked Adam's approach to the grease groove issue. I think of this as single point broaching or planing on the lathe. I employed a similar technique on the Bridgeport when I needed a square through hole on part that I was fabricating. I had no broaching capacity. I made a crude single point tool from a broken carbide end mill. I used the quill stroke to open the round starter drilled hole and to square the corners. Adam's skill and methods refinement outclassed my crude setup, but my method met my requirements. I like Adam's detailed explanation that matches well with his video skill. I think that I would have pressed the bushing into the trued gear bore and finished the bore to size on the Monarch, and then completed the grease grooves in that Monarch setup. I don't yet have the luxury of multiple capable lathes and I don't have a set of expanding mandrels. My methods reflect my shop limitations and my experience. Kudos to Adam and to any of us in the community who can expand my learning and skill.

    A pressure washer would have been the fastest and easiest way to clean that gear. Having a cheap electric pressure washer around to do jobs like that is well worth it, you can get a decent one for under $100.
    There are a lot of customers who don't realize that most machine shops have to order material for every job. Waiting on material is a major component in the total time it takes to finish the repair.

    Nice, Adam. Knowing how much you love your shapers, I was absolutely sure that I was about to see you use one on that piece of bronze - which I have never seen done before on an inside diameter like that.

    Hitachi/John Deere steps the end of their hard steel and bronze bearings like you did there. Its way better than a chamfer IMHO especially when using portable pulling cylinders out in the field. Gets everything started straighter and helps prevent galling due the the bearing not centering correctly. (most of the time!)

      Well this video is from a while back and is in his "old" shop. I hope that doesn't bother your "sleepytime!!" After he recovers from the nasal surgery, we will all be ready for "new shop stuff"!

    I really like how bronze and brass machines. Too bad they're "limited use" materials :P

    Not related to the current video. Learned about this from one of Jody's old videos. For rust and mill scale, he used the Scotch-Brite Bristle Disc in a ceramic 36 grit. This is available on Amazon in the Cubitron store. Found that this works much better than anything else I've tried for rust and mill scale. When welding in a defense plant we had to use the Bernard Shortstub stingers, all my personal gear now uses this. Give one a shot if you get a chance. This is especially usefull in tight quarters. Enjoy your videos, Thanks
