Home Shop Machinists Podcast – Episode 17 – Home $hop Machini$t

2 episodes in one month!  We can’t believe it either.  Don’t worry though we didn’t cut on quantity to get it out – this episode is still over 2 hours.  We won’t talk about the quality.  Max, Stefan and Justin give shop updates (it has been about 4 months since Stefan has been on – that’s long enough for Stefan to build an entire Saturn V rocket in his basement).  After that we talk about making money in the home $hop – when your hobby turns into a business.  And no we aren’t the Business of Machining Podcast.  In between the weirdness:

  • Stefan is busy making telescope parts for the Hubble Space telescope a local company requiring telescope parts.
  • Stefan is on the lookout for a new lathe.  He would like a Hardinge HLV (don’t we all!).
  • Justin and Max suggest looking at the Taiwanese clones like Cyclematic or Feeler
  • Stefan broke down and bought a face mill with carbide inserts:
  • Lancaster Watch Tools: https://www.instagram.com/lancaster_watch_tools/
  • Max is working on a license plate holder for his AMG.
  • Justin’s diamond dressers for the bench grinder are now for sale.  You can find them on this site.
  • Stefan is the reason why small shapers and grinders now cost an arm and a leg and everyone wants one.
  • We talk about turning your home shop into a business.  Over the past few years Stefan has done more and more work for clients.
  • Keep it a hobby – you don’t want to destroy the fun in your life!
  • Stefan does some work for this guy: https://www.instagram.com/stories/watchmaker.kl/
  • Justin is upset about all the Bang Good advertising on Youtube.

  1. Wonderful episode guys.

    Re Linley jig bore, I own probably one of the last one ever made and can confirm the ways are square, not dovetailed. Still, that allows some light machining to be done.

    • Thanks Daniel. Yes you are 100% correct. The early Linley Jig borers (which I had – I sold it because I didn’t have any tooling) had dovetail ways. That made them better for milling but ironically the collet system was terrible for holding end mills as they would pull out due to the collet design. Your model has the traditional jig borer ways (which is worse for milling) but with an improved collet system that uses ER style collets. Whatever the case both are beautifully made machines perfect for the home shop. Still miss mine but was a good lesson in buying an old machine tool – make sure tooling comes with it.

  2. Great episode guys.

    The Taiwanese Hardinge copy you’re talking about is a Feeler FTL-618; they were (and still are) sold in the US as the AML618 and CTL-618. Chris Vesper (@vespertools on Instagram) has a very well kept example.

  3. Ah, my drive to work is fun again! Not surprisingly, I haven’t finished listening yet, but I couldn’t resist chiming in.

    For your one-off thread cutting escapade, I suggest 3D printing the custom gears you need. I did that once to make a super coarse acme thread. I measured the center to center on the two stub shafts and made a custom (totally random) pitch gear set with the right number of teeth and the exact center to center I needed. I also made them as thick as possible. https://www.thingiverse.com/thing:2878559

    When I bought my Hardinge TL (and sold my “made on D-day” South Bend), it felt like moving up to an “adult” lathe, even though it was a smaller bed. Major step up in features and ease of operation. The TL lathes are pretty darn odd-ball in the Hardinge world; they have a dovetail AND an inverse dovetail sticking up in the middle of the bed that the tailstock runs on. The stupid things don’t even have a real manual (other than a nice sell sheet). Frustrating. Anyway, Stephan would clearly enjoy a Hardinge or clone; they are super nice to work on, and that 5C nose is sooo cushy!

    Invention. Having 54 patents I’ve got some experience with the process. There is a significant chunk of my patents that are more defensive and “I’m almost positive this will work”, in addition to those that are protecting things that we actually built or might build. I’d be happy to blather on about the subject if y’all are interested. I’ve also worked with one of those “guys with wacky ideas”. I had some fun making a couple of prototypes for him, but I went into it without any expectation of money, despite his song and dance.

  4. This and BoM has become my two favorite podcasts. A joy to listen to while doing things. Don’t have a shop but was listening to the episode while putting together my bicycle after taking it apart completely and cleaning it. Hope you have a good Walpurgis Night 😀

  5. Have you guys quit with the podcast? I so look forward to the show and the beer selections.
    Me and the 5 other people (and your mom??) are looking forward to the next show.

    • Hey Ed. The podcast isn’t dead – actually we are going to get back into recording this week. Max and I had a number of life events hit us that caused us to hit the pause button on some of what we have been doing. I guess that is the nature of a hobby – certain times require you to pause and take care of more important matters. But hopefully going forward we will have some more time to record again!!!

  6. Good to read that you’re having a next episode coming. I’m waiting impatiently. You should nag Stefan to become a permanent host, I really enjoy his insights. And judging from what he posted in the forum recently he seems to have too much time on his hands. I reeeeeally wanna hear him talk about his new tool grinding machine!
