Love seeing the more specific parts of being a self taught cnc machinist. Sometimes the grand plans sound like better video titles, but a simple walk through of a problem you had was a refreshing way to share and learn with you. Thanks for all you do!
Great fun to watch you work, John. You're passion IS your work and that's a great place to be in life. Now I need to go and buy one of your beautiful knives...
I didn't know about that caliper trick either. Thanks. Btw Your progression over a few short (long too) years has been phenomenal. You're just one of those guys with the right combination of brains, creativity and drive and passion.
Sweet! Reminds me of the old days of your channel. An all brass and stainless knife would be cool! Thanks for taking the time to make and post another vid John!
kudos to you're admittance upon learning the depth measurment on the calipers dude. There is only a handful of honest people out there who will admit those type of things. keep up all the great work !
Jesus John. My mind is blown. I just can't believe how much time and effort goes into the tiniest parts. Maybe you need to start making watches!! Seriously, I'm really impressed. Love it.
So, fun in the Dwarf Fortress 'loosing is fun' school of thought. My little shop runs on a continuous supply of such fun; I'm glad to see that you are doing far better and still having 'fun' at it :D
that is a super awesome machine you have there. and your skill level is beyond great. thanks for the inspiration and some day I hope to be making parts on a machine like this one. keep up the good work John.
Great video man! I love seeing how other people process a part. The C-Axis thread milling is an awesome idea that I may have to pitch to my supervisor when the time arises. Excited to get to shake your hand at the SMW open house!
Happy to see your making videos again John. I know what you mean about "Grimsmo time" before I opened my shop I could estimate times much more efficiently but when your running the show and producing parts things seem to take many times longer. Too many days have gone by where I didn't even realize several hours had passed because I was so busy but the work completed didn't make me feel like I did anything at the end of the day. Thanks for sharing your journey with all of us!
Nice Video. I didn't read every comment so I don't know if anybody shared this: I use a combination square, 2", 4", or 12" for my material stickout. Lock your caliper to the desired stickout amount, then set your combination square to your caliper. You can find one at any hardware store for around $10, or you can get the better Starrett one. If I use my caliper for stickout, I always lock it to my dimension and use 2 hands, one pulling the material out, the other one holding the caliper up against the collet. It really is impressive what techniques people come up with when all they have is their imagination. You give 10 machinists the same part to make, they will make it 10 different ways and have the same end result, besides overall time, which depends on your equipment and skill level.
Amazing. I also felt dumb when I learned that caliper thing. But now I feel smart when I can show people how useful it is. I hate using the regular depth gauge. Some times I cut them off when they get in the way of fitting into a small area and I hardly use it.
This is just bad ass man, I cant wait to have toys like this! When it popped the spring loaded screw out I lost it! so awesome! Im still in the DIY stage of tools, cnc router, co2 laser, but I am coming up fast, 2018 will be my year to get a VMC. Keep cranking out the videos! Thanks!
You have the ability to grow faster than I did, times are different and better now, easier access to more awesome stuff and knowledge for cheaper! I saw your IG page, you're well on your way.
Awesome man I appreciate it! Also, thanks for checking out my IG! I thought you and John Saunders might like what I do since you both mentioned being into computers before machining, I will see both you guys at the NYCCNC open house in a couple months, my girlfriend and I will be driving down there to check it out, I live 2 hours north of John near Cleveland. I'm going to bring a handful of the custom PC modding parts I make. I look forward to meeting you guys!
The finish on that torx is incredible - it's amazing to think that a big machine is capable of holding such tight tolerances on parts. I wonder how sensitive the force sensor must be, to detect resistance if the torx isn't there - I'd be interested to see a quick video on that feature! Does it let you set force limits etc.?
Hey John, I was thinking about your process, and I think you could benefit from this. Before you do your parting. 1- stop main and bring in subspindle and clamp 2-unclamp main spindle and pull out however much you need for the next part (you have a lot of coolant and very little chips to worry about getting in the collet of the main spindle) 3-clamp and part it off and finish the program by doing this you could loop your program x times and when the machine stops do your checks. You could probably get crazier with this if you wanted to, maybe adjust the clamp sensor so that when no bar is present it alarms with no clamp ect (there is probably a better way, but thats one idea hahh). You might already be doing this, if not, you should!
Great video, John! Thank you! Couldn't believe it was 19 minutes long, felt like 3-5 minutes... Even though John Saunders suggested you to have shorter videos, I would say that long videos are also awesome, especially ones like these! Keep up the good work!
Set your calipers at the desired dimension with the lock screw then pull your part out to length, should be more consistent and faster to do. That spindle speeder is awesome!
Yeah seconded, just lock the darn thing Also, for production parts where you're going to make them often, you can make a little L-shaped gauge that's got the correct step length just built in. Slap a label on them, or engrave the part name/number/offset length, and start a little collection of them.
I will go one better for the tech geek step, why not add a line of code so the machine homes one of the flat tool holders like the parting tool in front of the bore to the programmed stick out dimension, then just slide out against stop, clamp, and cycle start. :-)
i put teflon tape on my ejectors to keep the from backing out and getting stuck. sometime we put it on the outside collet threads when we do iron or hex that makes really small chips
And if you could not get to that side, you could always use a few pieces of threaded rod with some double female connectors. so I guess the only step left on the fasteners is to lap the bottoms to a mirror finish?
10:32 Haha I just saw John Saunders video, and he did the exact same thing to check a part in the vise! I never knew the ends of calipers could be used like that, much handier ;-)
Don't feel bad, I use calipers mutiple times a week and I didn't know about it until now. Loved the video BTW, reminds me of the old school knife making Tuesday videos.
Just so you know, the collet wrench you mounted to the table is designed and used to put the collet in and out of the spindle adapter. There is another wrench that slides over the back of the collet with a pin that fits the keyway, this wrench is used to hold the collet in place while putting in collet stops in the back threads. You can google 5c Collet Stop Wrench and see an image of the wrench with the key if you don't understand what I'm saying.
You should definately "just" gogogo. MasterCam is reasonably easy to pick up. And there's loads of CNC 101's floating around on the web. Shouldn't cause you too much of a headache if you've got manual machining down already. Only real hurdle is memorizing G and M codes, but reference sheets and time will help you.
Check my instagram post if you can, it's almost ready for prime time! Sad to say that my Grimsmo Bearings were noticeably worse than the Boca ones. I'll show that in an upcoming video. But the spinner rocks now.
JohnGrimsmo,, , the crunch time is gonna be deciding the price point you want to aim for,. A lot of the high end spinners are being cloned, (by you know where), almost as fast as they're on the market, ! I think a lot of people are heading down the cheap and cheerful route, rather than waiting for the "holy grail", which often comes with a hefty price tag.! . Spinners are not like knives, where the devotees worship the hallowed ground you guys walk on.. A prime example is the torqbar, you can get a decent clone from Amazon or ebay for around 5 dollars, all the masses want is a fidget toy at the end of the day, it's not the same as wanting a norseman which will be a heirloom item. Anyway, if you want to send me an early prototype, I won't say no, ha ha, good luck with the diversification, cheers, John .
Normally I do turn the thread but it was making too many burrs on the thread because the stainless is hard at 45rc, so threadmilling seems to be producing a cleaner thread. A lot slower though.
You could re-run the OD turn like Sam Stone mentioned, then re-run the spring pass- allowing the OD turn tool to debur, and the OD thread tool to re-top to ensure a useable thread. That may get you out of the woods with conventional threading tools. like the Iscar IQ DECA with 10 corners on an insert.
John, have you ever heard of using threads to create knurling? Did you ever try it? It seems to me that you would have allot more control over depth and pattern, if it is possible.
Like thread rolling? I know it's possible and done a lot, but probably really hard on these small parts. Maybe easy, I don't really know. This way and traditional single point threading seems to work great.
for finish on a part with an small to wide diameter part use constant cutting speed, that will give the same finish on the whole part. example : G96 V120 (don't forget to use G92 because the machine will go to its max spindle speed at close center of the part) then in the coming blocks use the same programing with G01
Hey, Sennheiser released a decent gopro mic, which might help a lot with the convenience aspect of making videos without the pain in the ass of getting out an external mic.
Hello sir I m Daljeet Singh from India and I have 8 year experience as a cnc turning or cnc milling operator and setter I want to go abroad plz tell me how can I get job related to cnc
Hello John, I have a question for you: Where did you get the Post Processor for the Mori Seiki? I don't think it's in the Fusion 360 PP library. Do you write it yourself? If yes, is it hard or something you can learn in a reasonable amount of time? Keep up the great videos!
Why don't you lock the calipers at whatever depth you need and push the rod in? That way you won't overshoot and have to pull out the rod again. BTW, looking at those spinners it occurs to me that all the ones I have seen are symmetrical, but they don't need to be as long as the center of mass is on the axis of rotation, so you could use materials with different mass if you wanted to make an odd looking one :)
Why not mill a tool to set it to 0.350"? I doubt it takes you a long time to set each bar but there is time to save with the cost of a piece of aluminium with a hole milled in it.
Love seeing the more specific parts of being a self taught cnc machinist. Sometimes the grand plans sound like better video titles, but a simple walk through of a problem you had was a refreshing way to share and learn with you. Thanks for all you do!
Cheers Ian!
Thanks John for taking the time to produce that in brass so we can see most of the operation.
The Nakamura is so precise!!
Totally worth it in brass, sorry it was blurry at the end haha. Hard to see the focus on the gopro screen with the macro lens on.

This is the kind of your videos i like most. Thank you for sharing.
Woot. More to come, this one was fun.
Using the torque sensing to check your part the way you did was a great use of the machine. Thanks for sharing that idea
John, great to see how each part is made. So neat to see it slowed down and without coolant. Thanks for sharing.
Sweet! Reminds me of the old days of your channel.
An all brass and stainless knife would be cool!
Thanks for taking the time to make and post another vid John!
Thanks Brent, making the video did feel like the old days, it was fun.
kudos to you're admittance upon learning the depth measurment on the calipers dude. There is only a handful of honest people out there who will admit those type of things. keep up all the great work !
Glad to see you are making a few more videos. Love the fine work on the hex cutting and the testing of the socket...
Jesus John. My mind is blown. I just can't believe how much time and effort goes into the tiniest parts. Maybe you need to start making watches!! Seriously, I'm really impressed. Love it.
So, fun in the Dwarf Fortress 'loosing is fun' school of thought. My little shop runs on a continuous supply of such fun; I'm glad to see that you are doing far better and still having 'fun' at it :D

Wish I had that lathe. Someday! Have a '95 MORI Seiki SL25Y. It's awesome how in-depth you are in your videos. Thank you
Great video man! I love seeing how other people process a part. The C-Axis thread milling is an awesome idea that I may have to pitch to my supervisor when the time arises.
Excited to get to shake your hand at the SMW open house!
Hey John & Eric, been a long time follower of your videos, the work you guys produce is stunning! Really great to see! Cheers, Doug

Cheers Fred

Awesome Video, John! You inspire me to be a better machinist.. and a better person. Thanks for sharing your journey, man!
Damn dude the pill bottle and the load sensor thing is awesome. Nice looking machine shop too. Keep up the good work
The quality of these parts is insane...thanks you for sharing
Awesome John, good to see you back putting out a few videos. This was really a fun one (as your title says!)
great tip with the calipers.. used them for years never considered using the back step
Amazing. I also felt dumb when I learned that caliper thing. But now I feel smart when I can show people how useful it is. I hate using the regular depth gauge. Some times I cut them off when they get in the way of fitting into a small area and I hardly use it.

John said 5 minutes! Thanks for the video, great tour of the lathe.
Nice video John and cheers for the caliper trick! self-taught we live n learn :)
To help keep the glass clear on your door, have you tried super hydrophobic coatings? My wife just got aquapel for her car's windshield.
Amazing man . It’s unbelievable to see this machine make tiny precision parts .
The finish on that torx is incredible - it's amazing to think that a big machine is capable of holding such tight tolerances on parts. I wonder how sensitive the force sensor must be, to detect resistance if the torx isn't there - I'd be interested to see a quick video on that feature! Does it let you set force limits etc.?

You might already be doing this, if not, you should!
We have none stop issues with our sub Spindle parts ejector and through coolant.
Great video, John! Thank you! Couldn't believe it was 19 minutes long, felt like 3-5 minutes...

*cough*, bar feeder, *cough*
If there was room for one!
Great video John. I really enjoyed it.
Well you answered the question I was begging to ask at 18:40 about why you are not rotary broaching the torx cut.
i put teflon tape on my ejectors to keep the from backing out and getting stuck. sometime we put it on the outside collet threads when we do iron or hex that makes really small chips
Good tip. First time it's happened to me but I can imagine how annoying it would be if it happens often!
Neat that you can control the speed of turret index, never ran a lathe that did that
Awesome! I remember my first CNC lathe, a Nakamura Tome TMC3 with FANUC control system! Boy have things changed!
FANUC NC units are so. . . .themselves. Not exactly hating here, but. . not a fan either. Still "better" than SIEMENS, tho. :P
And if you could not get to that side, you could always use a few pieces of threaded rod with some double female connectors. so I guess the only step left on the fasteners is to lap the bottoms to a mirror finish?
Why dont you just use a tool as a stop for the bar whenever you just feed it manually? Like the parting off tool holder or an empty drill holder?
Thanks for the tour John.
Thumbs up!
Cool, informative, motivating. Thanks for the ride-along, John!
-- Cheers, Gary
You've got it Gary, thanks for watching!
10:32 Haha I just saw John Saunders video, and he did the exact same thing to check a part in the vise! I never knew the ends of calipers could be used like that, much handier ;-)
Use purple loctite to install the ejector/stop into the collet. Purple is the MIL stuff for 1/4 and smaller fasteners.
Don't feel bad, I use calipers mutiple times a week and I didn't know about it until now.
Loved the video BTW, reminds me of the old school knife making Tuesday videos.
Awesome. It felt like the old videos, I enjoyed it.
Great video as always! Could you have run the sub spindle in reverse to get the spring part out?
great videos ...but I still not understand why you need the AS200 and the Tornos??? only because you can or is there a practical reason??
Why do you thread mill it instead of just turning the threads normally?
Shouldn't you have a pill bottle for the good parts, and another pill bottle for the rejected parts? Or do you just drop them down with the chips?
Just so you know, the collet wrench you mounted to the table is designed and used to put the collet in and out of the spindle adapter. There is another wrench that slides over the back of the collet with a pin that fits the keyway, this wrench is used to hold the collet in place while putting in collet stops in the back threads. You can google 5c Collet Stop Wrench and see an image of the wrench with the key if you don't understand what I'm saying.
Ooooh I did NOT know that, awesome! Thanks for the tip.
Hello, can you help me with profil knife for cut tip on drumsticks?
Have you tried multi-point thread milling on the threading op? Seems like it might save a lot of time if you're doing multiple passes
i want to buy a Damascus Grimsmo Norseman but cant find them anywhere, Are you guys brining any to blade show 2017
why u don't make hydrolic bottle jack using cnc lathe.
How do you choose the knife names?
nicely done. bravo. I'd LOVE to learn CNC. I've got wire frame 3D modeling down. just need to import that into mastercam and learn that crazy program!
You should definately "just" gogogo. MasterCam is reasonably easy to pick up. And there's loads of CNC 101's floating around on the web. Shouldn't cause you too much of a headache if you've got manual machining down already. Only real hurdle is memorizing G and M codes, but reference sheets and time will help you.
did you move into a big shop. i remember your channel when you were in your garage.
well done.
nice machinery you got there
btw u can machine a rod with .355 deep hole in it and set it really fast.
What brand lathe would you recommend for the garage hobbyist? Are the Grizzly lathes good, or would you recommend something else?
whats your weekly output for knives ?
What magnifier are you using to check the Torx?
First thing I thought was telescoping magnet. Machines are fun.
How do I get on your books for a rake thank you
I've been machining for 7 years and never knew about that caliper trick lmao
You ever tried RainX on the inside of your window?
Great stuff John,, couldn't fail to see the spinner on the table, what's the latest,??
Check my instagram post if you can, it's almost ready for prime time! Sad to say that my Grimsmo Bearings were noticeably worse than the Boca ones. I'll show that in an upcoming video. But the spinner rocks now.

Silicon nitride hybrid bearings. Those are the equivalent of using titanium for your screws (-8
same here man, didnt know that with the calipper eather !!! genious
Glad I'm not the only one haha.
Holy crap, I've never seen such a small end mill. Do they make smaller than 0.020?
Really nice ideas. Gj. I'm working on the machine Mori Seiki zl153.
Why would you thread mill when you can just turn the thread?
Normally I do turn the thread but it was making too many burrs on the thread because the stainless is hard at 45rc, so threadmilling seems to be producing a cleaner thread. A lot slower though.
Sure. If you want to speed up, you can just turn over the top of the thread.
You could re-run the OD turn like Sam Stone mentioned, then re-run the spring pass- allowing the OD turn tool to debur, and the OD thread tool to re-top to ensure a useable thread. That may get you out of the woods with conventional threading tools. like the Iscar IQ DECA with 10 corners on an insert.
You could use a topping insert or a multi tooth thread mill. That machine looks pretty awesome. How do you like it?
John, have you ever heard of using threads to create knurling? Did you ever try it? It seems to me that you would have allot more control over depth and pattern, if it is possible.
Like thread rolling? I know it's possible and done a lot, but probably really hard on these small parts. Maybe easy, I don't really know. This way and traditional single point threading seems to work great.
It's cool that you are self taught nice job
cut a thread with profile grinded insert in three passes. it is much faster and better thread. nice clips you make. best regards...
you have got one of the sleekest lathe carousel out there
for finish on a part with an small to wide diameter part use constant cutting speed, that will give the same finish on the whole part. example : G96 V120 (don't forget to use G92 because the machine will go to its max spindle speed at close center of the part) then in the coming blocks use the same programing with G01
Hey John - is it okay if we use a snippet of your video in a machinist compilation video we are doing?
like your videos man you have a great shop
Really nice video. Thanks for sharing. A second spindle and a parts ejector/catcher is really cool. Let's that baby run all night. :)
I'm like a kid in a candy store. Nice job.
Tom from Oxtools taught me that "trick" with the calipers.
interesting,jnspiring and well filmed,thankyou
Boom. Appreciate it!
Are you designing a new knife yet?
Really cool video, by the way, how much coolant do you go through in a day? It must be a huge amount! is there any way of filtering it and reusing it?
"Complicated, frustrating and exciting." That's the formula for awesome stuff to happen.
Bom dia! Não tem como traduzir para o português? Obrigado!
I've never seen that with verniers either and i work with some guys who've been doing this 40 years :)
I learned something. Thanks for sharing.
Have you done an apprenticeship?
Hey, Sennheiser released a decent gopro mic, which might help a lot with the convenience aspect of making videos without the pain in the ass of getting out an external mic.
Great video! Shop maint, metrology, process innovations, chips, cool parts! Thanks for sharing!
Hello sir I m Daljeet Singh from India and I have 8 year experience as a cnc turning or cnc milling operator and setter I want to go abroad plz tell me how can I get job related to cnc
Hello John, I have a question for you: Where did you get the Post Processor for the Mori Seiki? I don't think it's in the Fusion 360 PP library. Do you write it yourself? If yes, is it hard or something you can learn in a reasonable amount of time? Keep up the great videos!
If you ever offer another option besides full price pre orders Id be a buyer.
Why don't you lock the calipers at whatever depth you need and push the rod in? That way you won't overshoot and have to pull out the rod again.
BTW, looking at those spinners it occurs to me that all the ones I have seen are symmetrical, but they don't need to be as long as the center of mass is on the axis of rotation, so you could use materials with different mass if you wanted to make an odd looking one :)
i should have bought a swiss type for your kind of parts
Why not mill a tool to set it to 0.350"? I doubt it takes you a long time to set each bar but there is time to save with the cost of a piece of aluminium with a hole milled in it.
