John Grimsmo of Grimsmo Knives and John Saunders of NYC CNC discuss their success, struggles, goals and more as machinists, business owners and entrepreneurs.

    Make vs. Buy - The never ending story

    Make vs. Buy - The never ending story

    John & John go over the never ending struggle of the classic make vs buy scenario. This time they are talking about making a custom shipping table to help speed up Saunders' work flow. Grimsmo has a Canadian version called FlexPipe.
     
    Saunders' has been doing some WORK when it comes to Automatic Brix reading of coolant systems. He has been using a digital refractometer that you can find two versions of them here.

    Business of Machining Podcast = The Manufacturing Entrepreneurcast

    You CAN Be The Crazy Guy In Your Garage Forever!
    The idea of expanding beyond oneself or even becoming self-employed isn't enticing to everyone---and that's okay! Grimsmo reflects on his evolution from solopreneur to entrepreneur and Saunders shares an experience with an electrician who likes his gig just the way it is.

    Speaking of Solopreneurs, check out this shop update with
    Adam Demuth, an incredible machinist who made the shift from a 9-5 to being self-employed. If you're not into stress but want to run a business, Adam's zen-rific perspective on entrepreneurship is perfect for you! Also, check out the Precision Microcast hosted by Adam and Joshua Hacko from Nicholas Hacko Watchmaker!
    Lockwood Begs to Differ
    Idealizing the infallibility of robots is nice and all but Rob's administering a heavy dose of truth!
    "Why are we not better at this already!?" 
    Saunders is disappointed in our lack of progress when it comes to payload issues for FANUC robot arms. Not to worry, 5th Axis is working on it! Check out their videos here!
    THIS SUCKS! (but it will be worth it)
    During Phase 3/4 of Nuking the Shop, Saunders faces the fact that all material and supplies must be removed from the racking and the team will have to start from square one. While discussing one of their new favorite topics, tracking inventory, we learn that the Johns are taking different approaches when it comes to quantities!

    BRIX, The Holy Crap Scenario, and "Screw This, I'm Goin' Home!"
    The guys outline the specifics of their automated coolant delivery systems and air lines. They discuss solenoids, refractometers, ball valves with external motors, IoT (internet of things), Mixtrons, and MORE! They share progress, plans, and solutions to problems. Find out what Grimsmo means by "The Holy Crap Scenario" and the situation that made him throw in the towel, so-to-speak.
    The Smoking Gun--I mean, Knife?
    Grimsmo tackles the lowest hanging, highest yield fruit during his "days off in the shop"! A few episodes ago, Grimsmo knew the one thing he could do to increase production right away and he nailed it! Now, there's something nice--uh, Norse, that can run lights out on the Mori!

    RUN FROM HERE - Running Code from A Certain Point
    SMW is focusing heavily on developing reliable processes when it comes to posting code. While they used to run from the "Run From Here" feature, things have changed....

    Auto Grinding & Horizontal Machining

    Auto Grinding & Horizontal Machining

    Grimsmo has made some glorious progress on the kern. They have finalized an auto grinding routine for Rask blades. While Saunders' and their team have been toying with the idea of buying a Horizontal machining center.
     
    Saunders' also has some awesome upgrades he is adding to Proven Cut.

    KERN IT UP.
    Grimsmo machines his own ER 16 collet for the KERN! Wait until you hear about how he made this monolithic-integral ER. All this talk about holding parts on center brings back a good ol' Memory with Marv. Saunders recounts an accuracy test for cylindricity on the KERN--Swarf VS. Polar Interpolation in Garmisch- Partenkirchen.


    Threadmilling. Single Point or Proper Threadmills? Tool Standardization?
    The guys dive into threadmilling and tooling up machines; including single point versus proper threadmills, tool deflection, and whether or not to buy or DIY Collets. Regardless, the process needs to be reliable AND no matter how magical the brand of machine, it's still subject to the laws of physics.

    Click here for the Ultimate Guide to Threadmilling on NYCCNC (video and threadmilling calculator).

    HEAR ME OUT: The Synergistic Effect of CNC Theory.
    Saunders asks an interesting question, "Could the collets be made on the Nak?" At first it seems like an impossibility but with an open mind, new ways of thinking can lead to solutions you never could have imagined.
    Cogsdill Diamond Burnishing Tool on the Tornos: YAY or NAY?
    Grimsmo shares an update on the SAGA pen clips.
    Inconceivable---really!
    Saunders teases Grimsmo with the mind blowing video that's in the works. This Covid-friendly collaborative video about MetalQuest's INDEX MS40-8 will be about the harmony between machine capabilities and maximizing workflows. It's hard to imagine the back-work, which is all the more reason it MUST BE SHOWN! Get ready to reduce cycle time, increase output, balance cycle time between spindles, and more!

    Covid and Manufacturing: BIG GIANTS FALL HARDER.
    No one wants to speak too soon but there's been a sigh of relief that smaller manufacturing businesses haven't felt the same pain as the larger, often over-leveraged, companies. Seeing a "company consolidation" flyer in the mail for an aerospace company feels....weird.

    BUYER'S REMORSE?
    Does Grimsmo regret the large financial risk he took with the KERN given how 2020 has panned out thus far?

    TOTALLY REDEEMED AFTER BEING REAMED.
    A few episodes ago, Saunders called Grimsmo out for committing two cardinal sins of grinding. In order to make progress on the Rask, he decided to forego dressing and balancing the wheel before grinding the knife blade.
    Maybe Grimsmo's method of madness was intentional all along or maybe it was pure luck that resulted in the perfect recipe. EITHER WAY, IT'S FANTASTIC!

    Surface Finish Factors
    You hear about tool deflection, speeds & feeds, material type, and machine kinematics but what about presenting an even chipload/tool pressure to the cutting tool? Devon Dupuis from Autodesk and Saunders are collaborating on an OUT OF THIS WORLD part that relies on getting that chef's kiss finish.

    ERP: Permanent Product and Material Location
    A big part of implementing ERP is deciding where things will be stored. It might sound easy to have a permanent location for parts and material but Amazon outright rejects that logic. The key is to make sure the item can be located anywhere at anytime. 
    The Johns wrap up this 190th episode with probing, tool break detection, and what's on tap for the day!

    2020 - The Year of Custom ERP Systems

    2020 - The Year of Custom ERP Systems

    The year 2020 has not been exactly how we have imagined it. But it is in full swing for both Saunders' and Grimsmo, especially in the ERP department. Saunders' is cooking with LEX and Grimsmo is full GERP ahead.
     
    Both John's and their teams have worked hard to make it happen this year. It is a great teaching lesson for anyone to make the best of what you have. Focus on the things you actually have control over and take a step back.
     
    Grimsmo on the other hand is not happy with their Qualichen 450 and will be switching back to 251 for the time being. Also grinding rask blades on the Kern has been amazing! Saunders also touches on adding Shapeoko fixture plates to his lineup.
     
    NYCCNC has a great article on advice for buying a machine tool HERE:

    GRINDING WHEEL GRITS, RASK BLADES ON THE KERN, SAUNDERS CALLS GRIMSMO OUT, CHAMFER PSA, 2D CONTOUR VS. SWARF, FRUSTRATING FREIGHT FEES, GEOMETRY SELECTION HACK in FUSION 360, HIRING EMPLOYEES, FIXTURING FOR THE NORSEMAN, 3D PRINTING, AND NEVER TRUST ZER

    This podcast is GOOD VENTING and BAD VENTING all things manufacturing and entrepreneurship.
    Blade to the Grindstone
    After taking Saunders's advice (perhaps a bit too literally) Grimsmo takes a Zedaro Miltera Endmill to a knife blade and ends up with an incredible surface finish but the grinding wheel was another story...
    Throughout the talk of grit, mesh, and desired results, Grimsmo casually drops a bombshell---and Saunders calls him out immediately.

    PSA CHAMFER OR CORNER ROUND YOUR DANG PARTS
    A prospective hire for SMW finds it surprising to see how much deburring is done inside the machine! The guys highlight the benefits of chamfers and creative ways they've used different types of endmills to get that beloved edge break.
    Plus, Saunders shares his process for the SMW Diamond Dowel Pins, which come off the lathe a fully finished product.

    BUT, BUT....I WANTED IT TO BE COOL!
    Grimsmo laments the fact that he's using something a lot more simple than a Swarf toolpath but he knows the more simple, less exciting one still gets the job done. 

    FRICKIN' FREIGHT
    Without rhyme or reason, a national freight company adds limited access fees or lift gate fees that really aren't sustainable for SMW long term. Obviously, it's a problem that will need solving but how much action does it require? Saunders decided to take action based on an interesting strategy.

    THE BIG GOOD VENT
    Saunders shares his thoughts on things he's learned about hiring people and buying machines.

    HACK IN FUSION
    Selecting multiple chains of a sketch or contour can be a hassle, especially if you want to use that same geometry for multiple operations. VIDEO COMING SOON!
    Grimsmo's been learning better workflows, component structures, how to organize and lay out sketches all while keeping in mind future Grimsmo Knives employees.
    Fixturing & Tooling Standardization
    Grimsmo gives an update on the Norseman and while they're still able to make 6 knives daily, he's thinking about redesigning the fixture. The 2 long dovetail clamps on at each end causes the fixture to bow. The Johns discuss possible solutions and luckily, this is what SMW is all about!
    Standardizing tooling doesn't sound exciting but once you've implemented it, it's like seeing something you can't unsee!
    MINDS THEY ARE A CHANGIN'--and that's a good thing!
    RoboDrill replacement was going to be a Haas DT-2 but another consideration is MUCH more important to SMW than the fast rigid tapping.
