Nice machine John. That tool staging area is nuts. On that large radial nest at the end, you should add a small relief to the center contact area. Maybe 30 degrees worth at .01 deep. if the stock is slightly smaller, you'll only have linear tangent contact. the relief forces 2 lines of contact at all times.
Cover those Home Depot tables with thin 3/16” rubber. Nothing bounces or rolls away! Princess Auto sells it on the roll by the foot!!
Have you considered marking out the different areas in the tool changer with colored tape or paint to mark out the areas for the different types of bits?
bottoming out tools is not good for the tool runout because when clamping the tool might get pulled in slightly and it will effect the runout :)
Pro tip. At the 16:00 minute mark, you talked about stepping down, then over with 0.005” on the wall. This is a problem because as the tab gets thin, you’ll get a lousy surface finish. I suggest just stepping down in Z and no wall finish passes. You’ll be surprised how nice it turns out.
You dont have to spot drill if you drill with carbide, because it breaks the edges off the carbide drill. But if you drill with HSS it's a must because the drill will wiggle and the position off the hole is shity.✌
Dont forget to redesign your holder with that tail or CAMplete may not see coming collisions!
Tobad you didn't make the sofjaws a circular dovetail.
Just wondering why your not using carbide Drills? In most cases you wouldn't need to use reamers anymore and they just work so much better... and unless you smash them they're actually cheaper to run
Totally agree with you on deadlines.
what do you think of the heidenhain controller?
As someone starting my CNC journey it's awesome watching someone happy to do what they do even after all this time especially knowing where you started. Keep killing it John!
With some carbide drill designs there is really no need to spot with a separate tool. Sometimes for deep drilling it is good to come in and drill 1-3xD with a stub length and then bring out your longer drill, but not everything requires spotting.
If you have Z axis height issues why do you use such long collet holders ?
Hi, What are you using for coolant/cutting oil? Thanks in advance
Scheduling: Do an evaluation about how long you think jobs will take. Put them in a spreadsheet. Put the actual completed time in another column. Calculate % error. You can plot distribution of error and jobs or, at least do an average of errors.
Finally you can do an estimate and add in your average error and you'll have a better estimate of time. If you have really bad estimate, like it took 3 times, toss those data because it was a complete wrong estimate.
I've seen a lot of people not include downtime. Machines don't run forever. Try to track downtime per job so you can add it to your job estimate.
Yay, shout out to Madison, WI for the Moria.
Fallen down the rabbit hole again. Focus John, focus!
From what I understand, the ring on the inside of the collet nut is so that the collet can easily be extracted when you want to take it out. If that ring wasn't there it would be a nightmare to get the collet out of the mating taper, similar to why you need a tapered wedge to knock a Morse taper out of a drill press spindle.
I’d have to disagree with Cat being the gold standard, I’ve worked in machine shops since finishing my apprenticeship, and I’ve never once come across a matchine using a Cat tool holder, they’ve all been HSK due to their superior holding ability at high speed taking big cuts.
Use could use the dovetails to attach other things or 3d print holders for the soft jaws that use the dove tail to hold them.
10:08 when you realize this tool rack alone is probably worth more than your entire shop 🙈
Deadlines are huge. Love the progress. Keep these coming!!!!
Thank you for these awesome videos its a real treat for the end of day relaxation time.
I never spot drill 🤷♂️I drill primarily aluminum though. I just blast right through with cobalt or carbide.
I love air conditioning in my machine shop. It keeps my machines at the same temperature, my coolant is now cooled because it's 50 gallons of room temp liquid.

Altough I still to this day really really don’t get why you went with a Kern type of machine since it got ao many limitations for what you’re doing.... Hahaha. I would really invest and think about getting short holders. You really don’t need that long of a holder all the time, it obvious it gives a lot of total gage lenght issues for you atm. Loving the almost daily content dude. Slowlie but surely we will this machine make knives after knives after knives.
Hi John & Eric,
This has to be a gratifying moment for you guys. I have watched your videos since the garage and you guys have come a long way. CONGRATULATIONS!
John
HB Guilford company in torrington ct stocks short reamers in most decimal sizes, they work good
Agree with whomever you were talking too. Ive never spotted a hole and I don't even use drill bits. Only interpolated endmill holes. Drills are for deep stock if you're making knife scales drilling isnt necessary. I use 3 sizes of ball mill and 3 sizes of normal endmills to make everything ive ever made and sold.
Hey John, awesome stuff. Just a tip you probably already know, but when you tab stuff if you have the tabs on different planes it adds a lot of rigidity to the part
‘Gorilla Fab’ and ‘Moria’ should combine their CAT40 mounting tools into one tool! Use the Gorilla Fab tool as the base plate for the Moria tool and you have two ways to mount the CAT40 in one tool.
thank you for sharing awesome knowledge and awesome content.
very good video..thanks for your time
I used a KanBan system for tool and work offsets. I have little laminated cards that are red on one side and green on the other, and they say "Tool Offsets Set/Not set" and "Work Offsets Set / Not Set" respectively. That way if I am interrupted mid-setup, I come back to visual indicators as to the machine status. I just stick them in pockets next to the cycle start button.
I recently tried some ¼” 7fl end mills from garr tools and I was blown away. 3x the tool life of 5fl helical end mills. You should give them a try.
John when milling on the Kern instead of flooding the part with coolant can you use a misting spray for cooling the process being worked on or is the speed the Kern operates at to fast and generates to much heat for a mist coolant?
One of the reasons I asked is to see the machine working would be easier to film and for you to observe the program working especially with a new part you are manufacturing.

Hi John just in case your still looking for a better way to change your tool holders for your kern we use one of these for out c6 tool holders but it works with hsk as well its a big kaiser brand tool holder. Down the bottom of the page is the one your looking for if your interested. www.bigkaiser.com/en/products/product-accessories/tool-assembly-disassembly/tooling-mate

Put some trays on the tools set up table so you can put tools and separate them to keep them safe and sound since dropping tools is sad😭 remember how my carbide reamer exploded....
Hey man as far as forgetting to touch off tools. I always set all empty tool lengths to 99.999 so if anything the tool is just way in the air. And as far as spot drilling goes if its a hss 118 degree its best to spot drill. If its 135 degree there is no need to spot. I always spot after to chamfer with 135 degree and it saves tool life of spot because your not machining with the point.
Good night John, love you.
spotting depends, i mill and drill stainless steels up to inconels and i never spot. and they are all on round surface.
you did have a drill bit as it vanishes off the bench
On the topic of deadlines. Maybe setting goal dates would work better for you. The advantage of not having the stress in the shop, of deadlines. Is rather big IMO. You guys have what seems like a wonderfully low stress environment. Which is rare in many work places. So by setting dates you want to have goals achieved by, your not adding stress. If after 2-3 weeks of review or missing a goal then you can sit down and re-evaluate things. To go is this a viable, is it a pie in the sky dream, are we just pushing it off cause we dont have enough time or personnel.
I suggest this, cause you see, very goal oriented by like you said, you know that a deadline in these situations is fake. Hope you find something that works for you :)
oh hey what do you think of the bearing nut collet nuts?
Deadlines are just another challenge : you don’t know how to do something, you figure it out, and complete the challenge. Having a deadline is another dimension added to the challenge as now you have to make the problem solving fit in a time frame. You are very good at problem solving, taking on deadlines as another challenge should help !
Lol... the part about the 5th axis factory hole tolerance. They really do have the most ridiculously loose tolerances on their jaws.
I’m guessing all of the raw stock is for small Erowa pallet fixtures for the saga clips.
Still no TG collet in your CAMPlete toolholder model.
Miss running tormachs in the garage yet john?
He sure has come a long way since those days... 🙂
Any reason you do not number the tool holders to correspond with the location on the machine?
You’ve crawled, you’ve walked and now you’re starting to run!
Getting there dude! Can't wait to see the blade! Is Linda wheel back in play?
HSK IS has always more rigidity because it has side and Face contact and the (CAT) SK has only contact on the taper so the only real advantage of an (CAT) SK is that it is relatively cheap.
Yeah, but that’s only compared to equivalent size. Hsk 40e isn’t the same scale as cat40, so cat 40 is more rigid. Plus, the “e” type doesn’t have drive dogs, so it isn’t as suitable for stuff like boring bars and theoretically handles less torque.
Big Plus has taper and face contact.
Biggest benefit to any hsk is its ability to handle much higher rpm. However hsk63 is much more rigid then standard cat40, and hsk100 is much more rigid then standard cat50. Cat40 bigplus evens the rigidity gap but the clamping mechanism still cant support the rpm ramge that hsk can.
JohnGrimsmo light sabres !!!!!????
Flashlights ???
get different ER nuts as well 3 types ? one has a bearing in it, the ones i can afford dont thats all i know.
Client deadlines are real.. Personal ones seem sadly fluid and harder to keep.
Have you ever used a 3D Connexion mouse? They make working in 3D applications much easier.
Gosh darn it not first 😅
Woot
Show them who you really are, the local demons showed up and talked smack to me, this is where the nuclear bomb was created!
🔧😊👍
Kern is getting huge RUclips exposer because of you. They should fly someone over to help you with 'whatever'. Some extra training is always good.
