So are you excited that rasks are back or what?
So excited!!!
Honestly...more excited for the content. More excited for the journey, the process, the machining, and the learning you go through. That's why we follow along.
Very!!!
@@939Todd Cant wait! Almost more excited for new youtube content. Been playing catch up since yall started videos a decade ago! Keep up the good work. Glad to be on the List.
Even more excited when I can buy one!
Literally the most enjoyable video I have seen in a long time, I love these long detailed videos...refreshing to see the prototyping process documented like it actually happens in real life...keep up the good work, very inspiring stuff!
Started watching this morning before work. Been waiting all day to get off work and see this.
John, Fraser and who ever was involved in this. Thank you. Amazing.
With a video this long you could almost release it in movie theaters. Awesome work!
Love it when the problem or solution is finally found, great catch on the probe problem! Was fun going through that with you!!
I made a mistake at work this week.. nearly scraped the part and lost sleep over it. I needed to hear that speech about making mistakes ✊
I remember watching the grizzly run. Hard work truly pays off. Congrats guys keep it up
Wow John, your dedication is unbelievable...strong. Everybody make mistakes, and that's why people learn how to fix things. Respect...and may I say a wonderful 2021 for you, your family and your team...happy new year...🎉🍀🎉
Love all the learning that takes place, best part of learning a new process!
Great work John, keep it up! Love the videos and seeing the rask evolution!
The problem with the bad grind could be that the clamps ever so slightly cause the blade to bow when they’re tightened. You could probe before and after tightening to check this...
You may be getting thermal expansion of that delrin insert, how hot do you think that endmill and grinder get that piece? It has to be transferring heat into the part and thus into the delrin. You may want to look at using a more thermally stable material.
capnthepeafarmer probably not hot at all in reality.
can Imagine not getting really hot becaus of the amount of coolant used
@@perlsackhd3957 dude coolant gets hot- we have had coolant boil
Plastic tend to thermal expand quite a bit much compared to steel. Time to think other support material (maybe same as blade?)
@@chiefmachining7972 I can't imagine it does in a Kern. That machine is thermally managed like crazy.
Yes! A decent length video! Hurrah. Keep on it Frazer
The HMWPE maybe growing due to moisture absorption?
For the sun issue, I recommend semi-transparent shades. I have 10% shades on my windows. If you wanted to get fancy you get (or in your case probably make) motorized controls to raise and lower. When you want full brightness, open them up. Otherwise close them. Also will add a small amount of air barrier for the colder months.
I remember watching you two years back and the difference in your shop channel and content is crazy
I love seeing this kind of thing. As a maker myself, seeing others go through all that trial and error and problem solving is just fascinating. I love your machinery too, that door that opens to change tools is like something out of a sci-fi spaceship. 😁
@16 mins: For your starburst pattern, why don't you use a lollipop style cutter? You can then tilt the tool on its side (or rather, almost completely on its side, as you will still need a bit of clearance for the tool holder), and then you will be climb milling for both sides of the grooves. You will also be using a cutting edge further from the centre of rotation, so you will have more surface speed as well... am i missing something?
he is doing that by tipping the table with a standard ball mill
Matching the inside and outside milling is a touch of class and continuity. That Kern is amazing.✌
An hour and a half of pure bliss
The Error message you had, basically means that the posistionregulator couldn't hold the C Axis on spot. It just does not have enough power. It moved, the regulator goes out of regulation, because it can't handle it and then the standstill error comes up, because the C Axis moved.
A lot of people said thermal expansion for the Deleon part and I was thinking that also because I have less then zero faith in plastic lol but one other thing I was thinking was how your insert is Installed. I mean that if it is only bolted down with those three screws, perhaps coolant could be getting under the insert (or the part) just slightly when you are running it, causing some distortion. It’s hard to say just from the video not knowing how you have it installed. For example sitting in a pocket or not. Looked much better at the end, obviously you’ll figure it out. Happy new year, enjoyed the long video 😊
For the ball placing, maybe try following the design of electronics SMT pick and place machines and vibration "vibe" feeders?
So glad your back at it, missed your videos they are always very informative and interesting. Keep it Grimsmo
33:30 scallops is the word you were looking for :) amazing work btw. I will order one someday. On my bucket list. Your company might as well be called bucket list knives.
Nice to see such a high-end machine running linux.
42:34 maybe delrin absorbes moisture and changes size causing problems, also different thermal expansion rates can cause problems. Just make the spacer out of steel
Or peek, he wants to absorb the surface.
You gotta change the Kern offset page to diameter instead of radius, from one lathe guy to another.
Not too many gremlins left. Cool to see it coming back together again.
So glad videos are back! Seriously missed you guys.
Great problem solving on bevel milling.
I have "maybe" for the grinding uneven result. By selecting so fine grinding stone you glock up stone with material too soon.
I would try out more open structure wheel,, you still get shinny bling bling. Diamond straight in to fixture.. measure stone with laser- >diamond 💎- > measure again and Go for finishing grind 💪💪
I'm subscribed with the bell on but I haven't seen a single video in months until today.
You need that sucker tube as close to your work as possible. I have a similar set up on my surface grinder grinding carbide. Maybe watch how the dust comes of the sanding belt and position the tube.
Put that dressing pin on the fixture itself, no need to waste time and change pallets!
he have to have a pin in every pallet when he goes into production then when its running light out time to pallet change wont matter
I could see the forces involved in dressing that wheel affecting the fixture, too. For example, grinding vibration causing screws to back out just slightly. Harmonics are weird, and the kind of tolerances he's chasing here means he has to consider everything.
Look up in your Heidenhain user manual for the SYSREAD and SYSWRITE address tables. You can write a line of code to read or write data from the tool table, for example to reset your tool time after dressing the wheel, or after measuring it.
Hey John I know this video is kind of old but have you thought of running aluminum on the 4 degree jig instead of Delrin?
kudos for the XFCE :D
Please be careful with Eric's new air-filter, I can already see the bag filter catch fire with the sparks getting sucked in!
Would Camplete have caught the probe issue?
Give us a video showcasing some of the first runs of Rasks! Maybe before your next rask release make a video of the whole run, show us some of the sexy options out there on video!
Would love to see them go from finished product to being put together, boxed up, etc.
Does it make sense for you to get a fiber marking laser?
first video i've watched from this channel. it's making me want one
Me @10:30, damn you should really make a tool with a hopper solution..
John 11:00. Yeha... good one
Interesting idea. Don't start the thread from the very top, to prevent cross threading.
Excessive servo lag is bad news code, every couple months my floor mill will be in full rapid in X+, misread position, Estop and then I slam into the wall of the cab. Good times 👍
Nice beanie with the Pleiades star cluster logo. Best logo in the world.
John @49:00 that delrin is shiny because it's getting super hot from the grinding OP
Holy runtime... nice...
Soooo happy for videos again!
I bet that if you could go to the Grimsmos dumpster and collect some of those rejects you could build a pretty pristine Rask
If you are so lucky to work on nice products, nice machines and work in a nice environment. Time doesn't matter. Even troubleshooting can be fun .
Have a nice day!
Dude you’re OCD is a whole new level lol. Awesome work for real
Did you consult kern on if the spindle bearings can handle pressing in the detent ball?
It's no more force than you would see in a drilling operation. No problem
Of course it can. That's FAR less force than it experiences while milling.
Test to jump to the end of the text file by ctrl+end... pure end just jump to end of row.. (at least if it mimics how windows does it..)
glad to see eric in a vid again its been a while XD
Maybe dry run that particular op with an intentional under sized tool offset and then clean off the burr one last time
For the error and restarting your machine after a "crash" in the error screen thare should be a clear all kind of button and then you can repower the machine with the button above the e stop i had a similar problem with the machine i was working with had a little z offset error and it dove in 25 mm with a 40mm insertmill and it didn't like that
if you are polishing a lot of parts DLyte might have a interresting product!
Excellent video! Best of Luck in 2021!!!
For the problem window, sunshade on the outside? Awning?
Snagging one as soon as i get the opportunity.
Hé John, 14:00 its is surface speed. The outer parts rotate, the bottom stand stil practical. If you push a standing stil tool hard ennouf you drag it trou the matrial. That wats happening at the bottom.
Is there any way to get one made out of prototype parts? 🥺
Yes, thank you 😃👍
1.5 hours! YES!!!!
2x speed
57:33 SportsCenter theme
Get yourself some remote controlled blinds.
I love your knives and would love to get one one day, I have to ask though why the Kern? The work you do isn't actually that precise (volumetric wise) I've never priced a kern out but I would imagine it would be about twice the price of a matsurra LX or LF machine, and you have experience with that distributer. I know of several significantly cheaper machines out there that would far exceed your accuracy and quality needs that would have been better suited(IMO). I dont think you made a bad decision or anything im just really curious what your thought process was.
Probably ran somewhere around $450,000
@@Sicktrickintuner really? I always thought Kern were a premium price compared to Japanese brands. A matsurra LF is around $600 with a pallet changer I believe. I would've thought the Kern would've been around a million
Round estimates are north 800k including the pallet pool. Noone really knows because of the build sheet. Also think about the many thousands in pg stuff
@@split141x is that us or canadian? The quote I got for an LF160 was just over 600 cad including the 40 something pallet pool.
@@85CEKR so I've seen both cad an us lol. I literally am just regurgitating I've heard. At the end of the day, getting a super high tier 5th axis, with automation and tools was going to be big money. I'm sure John looked pretty hard at matsura as well. He mentioned it a couple times on the podcast a while ago.
How does the 160 stack up against the micro?
22:33 you over-tighten with the impact driver and then you check for less Newton-meters with a torque wrench? =/
. I’ve been missing you. Very good content, not too long
You need to get a welding blind to roll in front of your table when the sun is out
This news made me almost squeal with excitement.
been there done that :)
They make spray paint to frost that window or u can us spray deodorant as a temporary fix
i want to see your work ... FOREVER ... :-)
Nothing instock online?
Is it me our your compensation when touching the blade edge is in the wrong direction ? Should touching with the probe shaft not have push the cutter in the other direction ?
The way it works is that he compensates on the diameter offset of the tool. So it thought that the Tool is so small That there is a lot of Material left.
then for the second cut the tool moved in more to remove material because the machine thought that the tool is way smaller than it actually was.
Uhh, I can't wait to buy a Rask! I'm on the list, pick me!
Does the Kern *really* probe to nine places??
This is getting watched on the TV... feature length film
One question witch laptop do u got of msi? Good Video and I love ur nerdines
Classic proof that if you measuring tools is off, everything you make with it will be , including probe shaft ^^
I’ve been on your mailing/ knife list for over a year....when will I get a chance to buy one? :)
"Have you tried turning it off and on again?"
Dr. Evil would appreciate the "lazer beam" on the kern.
MOAR ERIC PLEASE!!!!!!!!!!
Well damn me, but kind of bored to see that you can't really design anything that can put the KERN up to the test. Kind of hoped to see some wacky stuff but hell at least we got KERN Instagram that shows us great stuff.
How many people made the list?
I wonder how I could get a friends and family knife? Hmmm?
The shape of the rask is very underwhelming. It leaves a lot to be desired visually. But the quality is so over the top as a collector I have to own it. It surpasses most high end custom knives I’ve handled.
0:04 kern uses xfce? wow.
Can you explain the 'wow' to non linux-experts?
Are you positively surprised, negatively, why?
@@hydrusje This was not judgmental. I was simply surprised.
Heidenhain 640 uses it
Tipy-Tipy is a technical term
Ok... Iwant one!!!!
In machining companies its always the same thing🙈
In 95% the "troublemaker" is standing in front of the machine.😅
NICE!! How did I just watch 90mins of shop life... 😐
John,
On future videos would you please try to remove the high pitch noise in the background audio. I know it is from your machines running but it seriously hurts my ears when watching your videos since it is just as loud as your voices in the videos.
Thank You,
Joe
Don't watch the videos then.
@@danielxoxx No need to be so defensive. It wasn't an attack, just feedback, and he wasn't rude about it. Might be able to remove the high pitched whine with a band-stop filter in editing, but who knows. might be too hard / too much work to do. Still, I can't see how polite feedback is an issue
@@danielxoxx chill out man , that was not cool.
Audition has a tool for subtracting background noise.
@@jimsvideos7201 awesome man thanks!
Just confirming Audition or Audacity ?
How come Sky doesn’t run the Swiss anymore?
Dang that’s loud.
So when are you going to invent the Full Grimsmo Lock, instead of a passe liner lock?
You should give more cnc time to Sky....it looks one very professional young worker....you should invest more in him......great job....
He was being trained to run the Swiss lathe. He wanted to move to the finishing department.
He could run machines all day for all we know.
If I grew up locally does that qualify me for friends and family knives? =)
