Solo Shop Adventures

[@lokis9210]

A Kern livestream with lights out and just it running might be be kinda cool :)

[@jasonruch3529]

TOTALLY!

[@omdesigned]

Sounds crazy but I’d venture folks would really appreciate seeing ‘their’ knife getting made. Just take images repeatedly along the assembly line, then compile a few at the end like they do with amusement park rides.

[@can.iman.]

I love these type of videos. I really would like to see more of them! I love your work, great job!

[@rorymccloskey854]

In work our dmg mori came with the coolant gun magnet combo. It works really well but after 2 years the paint is starting to rub off where the magnet is removed and replaced, I would advise painting a steel plate kern red as a protector.

[@nraynaud]

about the magnets: if you want to stick against a plate, the magnet should be potted in steel, that brings both north and south with high "conduction" to the plate. Right now the back pole has to come back in random materials like plastic, air, etc. Another consideration is that sometimes the steel plate you want to stick to is too thin, and it can't conduct enough magnetic magic pixies across the poles and the rest have to fly in the air (inside the machine this time) and it's not efficient.

[@claymantoo]

For barbed hose fittings I warm up the hose end a little with a heat gun. The hose fits with little effort. When the hose cools, it forms to the barbs.

[@JasonGrammenos]

So if your washdown hose comes from your pre mixed coolant supply does that not mean there is some risk that you could wash down a machine enough to over fill it with coolant? Would it not be more desirable to have the wash down come from the machines coolant tank, which means you are only re circulating the coolant already in the machine? Then the pre mixed supply is only used for top up and concentration adjustments.

[@Pleasestopthat]

Hey John! I’ve used lens profile endmills for contouring similar contoured surfaces on our DMU65 and it’s so much faster than a ball and leaves beautiful finishes especially when tipping the tool over at 3-5 degrees.

[@xenonram]

Yeah, any one of the circle segment tool forms would be better since he's using a 5 axis machine. A tapered EM would probably be best.

[@alexkern9134]

Can't wait for fusion to support circle segment.

[@SeanHodgins]

My kind of way to spend a Friday night.

[@jasonruch3529]

ABSOLUTELY!!!!!😎

[@mike7958]

Your floors are awesome! Such an easily overlooked thing, but when done right, Epic! Good job John, I'm jealous of your floors.

[@cncit]

I've found leaving the machines powered up even in power stop mode when they are not being used bumps my electricity bill up quite considerably! So I power them down now when they are not running parts.

[@hennaghansen9993]

regarding the Okamoto paperfilter problem: i used to work on a maschine with a similar paper filter and had the same problem. We used to bump up the feeding speed on the paper roll to avoid the paper getting clogged up and the dirty coolant would just run over the filter down the side back in to the tank. if possible maybe give it a try

[@danm3071]

Hi John, we created a custom m code on our mills to send spindle to safe position during pallet change or rotations. Easier and faster to type vs. absolute positions. Keep up the good work.

[@helicopterjohns]

Hi John, Yep, I have both the Dewalt 12 volt drill and the Dewalt 12 volt impact wrench and love them. They are very handy and lighter than the 18 volt monsters. Really enjoyed the video and appreciate you bringing me along on your journey in PRECISION knife making. It has been a long journey from your Tormach days in the garage at home. Ha Ha. You and Eric are the KNIFE GUYS!!!!!! Glad to see that you have added other HIGHLY MOTIVATED employees along your journey. Wish you the best for 2021 and the years to come. Get some sleep. Ha Ha John

[@LienNguyen-sw7kb]

Drill - bullnose rough then square EM finish. Extra operations but it keep your finish tool last longer

[@SR-ml4dn]

I Think you could benefit from version control your CNC code, so you not only have your code on the Kern in case of fire in the workshop. It also gives your better compare options and easier rollback and description for each version. Take a look at GIT and it's easy to use in cooperation with source tree.

[@solargoomba]

Keep up the amazing work! I love these solo old school vids. You guys are killing it and I still can't believe the Grimsmo Growth.

[@jacobbennett3731]

Mcmastercarr offers push lock fittings in npt that swivel once tightened. they are expensive but great.

[@nunocosta2641]

Hi, I really like to see your excitement and passion when you talk about your work and your machines, I've been following you for some time it's really fun to see your vlogs, keep up the good work and just try to do some more vlogs about the kern, I started to see you doing the first tombstone for the RASK but couldn't find the rest of the process video, have fun and stay safe

[@adammcneil1545]

Not sure if the kern has through spinal air, but if so it would be really cool to add a sub program that blows off your pallets before swapping them out! Just chuck up a pipe as easy as that.

[@zviper]

John I would just make a hook with the magnet, so you don't have to yank it off the pallet changer. aslo you wont be banging the coolant nozzle on the side when you put it away.

[@_domlnlk_]

nice to see you and your shop :-) love it ... greets from Germany !!!

[@Brad-vs1lk]

I would love to spend my Friday night using a bright shiny new Rask knife from Grimsmo knives!!! Great video!! Thankyou!!

[@gtcollection6933]

Remember when I caught one of your video back when you were just a kid and running benchtops. And by accident stomped on that recommended video to find you're now running a decent shop with production machine-tools. And That's Awesome!!! Side note You kinda look much older than you should though, working way too hard perhaps... keep the health priority man and good luck. Great vid btw!

[@jamesbarisitz4794]

To get the best fit up on barbed fittings, try soaking the end of the hose in a container of near boiling water and force in on wearing rubber gloves. ✌

[@jeremymurray8631]

For the tool chipping why not use a bullnose endmill or an endmill with a large corner radius? Does a radius in the bottom of the bore change the function of the bore?

[@databoy2010]

Why are you keeping the Kern filters in a wooden box? get someone to weld and paint a steel stand that would look a lot nicer than some random cart and as a bonus you could add an upright just to hold your gauges. Also, consider color coding your filters and bags so that you only maintain an inventory in one spot. You could use colored electrical tape or colored dots etc.

[@hampfi747]

The finishes of the handles are spectacular! I’m sure you could get a similar result with the blades and the process might be a bit less complex then grinding 👍🏼

[@GregsGarage]

I need to explore running multiple sub routines. sounds like how I break things up in fusion already, so it shouldn't be a far reach.

[@j.bin_genex1927]

world top maker of cnc knives maker 🎉🎉

[@M13asan]

Great videos John! Local Canadian here, getting my first norseman soon!

[@colbyweber650]

yo! use a bigger ball endmill tor a lower ridge height on your stepover.

[@oOMickanOo]

you need to do a new shop tour video. show it ALL as it is now when ur settled in.

[@Thewaldo12345]

Are you running any corner radius on the 1/8” endmill? Will def help the chipping.

[@flyincivic]

what locates the pallet on the tombstone?

[@MrJohnnyFred]

MDI will behave the same way on Fanuc if you change a few parameters

[@Daniel-vq9zb]

Not sure if you realize it or not but you flashed your shop address on the mcmaster order sheet

[@DeKempster]

Which is also on Google maps.

[@Daniel-vq9zb]

@@DeKempster didn't realize that I just remeber in a previous video I think when they were at the old shop he said the location wasn't public knowledge

[@mannycalavera121]

Love the videos, thanks for taking the time to make them

[@brian2k1]

Where can I buy that coolant spray gun?

[@465maltbie]

How often are you replacing the filters? Charles

[@ltborg]

What coolant gun is that? A video with more detail on how you run your subroutines would be awesome!

[@bigbird2100]

Great video 👍 rather than spiral down use a undersize cutter then use a burnish tool to Finish pass to finish size

[@deanropchan7213]

Any thought about making an integral knife John?

[@colbyweber650]

lower your rpm on the counterbore and cut your feed by 1/3

[@djeity]

Time to remove a few fingerprints from the door of that Kern!

[@SuperGohan512]

I'm still waiting to buy a saga pen , maybe this year?

[@465maltbie]

When I heard you were going to get a Kern machine I questioned why you would need one. The more you share some of the lessons you have learned from the more i appreciate your decision. Lots to learn, even for us older guys who have been doing this for a while. Thanks. Charles

[@jpolhamus71]

Omg!!!! I need a rask so bad! I cant wait!!

[@JohannSwart_JWS]

I presume you have backups, right? :-)

[@danharlan80]

Why not make a stud that replaces one of the screws on the coolant gun then just attach the magnet to the other side of the stud.

[@xavtek]

Yes I will take that smooth rainbow finish on my task thank you. 😂

[@issues1975]

where's the lefty tombstone video? ;-)

[@NH3rrm4nn]

Man love the kern . Love the.. work life vs home life honesty. I have a question, is the kern controller Linux based? Windows? I can't imagine they invented their own operating system.. mentioning finding the graphic file.. Nerds need to know! I love the fact you bought a machine above your knowledge level. Knowing full well you will be challenged, and will learn. Edit: Also.. that kern. Those rapids. That tolerance. So sick. Well done sir Double edit: you know how you comment before watching the whole vid? Yeah.. can you get kern with different control interfaces? Or rather, if you prefer one interface/controller can you swap it out

[@vilts]

While booting up it showed Xfce logo, that is a linux window manager. So linux it must be :)

[@joshuahuman1]

watch out when saunders visits he might put his logo in the corner

[@gredangeo]

Neat. :)

[@jeremyriggs8469]

Torque wrenches are typically calibrated with your hand on the end of the handle. So for what you're doing as long as you (and your operators) always hold it the same way you're getting that consistency. But if you needed to hit an actual number you'd want to hold it by the end of the handle otherwise you're changing the length of the level. Then you'll want to make sure all your operators use the wrench the same way to maximize your benefit of using one.

[@xenonram]

Torque is torque is torque. The wrench has no idea where your holding it. It's measuring torque, and you holding it at different lengths just changes the force you need to apply to achieve that torque..

[@patrickmartinez3217]

@@xenonram I agree, I did not think that where and how you hold a torque wrench changed the value of the torque you are putting to the part. We have torque wrenches calibrated through calibration services and they never ask us where and how to hold the torque wrench. I am not sure what this guy is talking about.

[@stuarthardy4626]

@@patrickmartinez3217 I think he is referring to the human torque setting FT

[@willej78]

@@xenonram That's simply not true; shorter lever = more torque applied before the wrench clicks. Experiment with a wrench and a torque analyzer and you'll see that the torque reading will be higher if you hold the tool closer to the head. I've had to show lots of very clever people this for them to believe it.

[@nimernimer]

Correct. The difference between accuracy and precision. Use the Handle designed into the torque wrench to achieve both.
