Interesting to see this in action - I've only seen it on wood previously. Surprised they don't supply a punch or press tool to create the driver grooves before the stock is loaded, to reduce the spindle load. That could create deeper (safer) grooves with less bearing stress.
it is amazing to see that you can pick up the long used and worn part and send it to the manufacturer for refurbishment. Also, much fun to watch the new big machinery
I've been looking forward to this video ever since I saw your instagram posts about this tool. I follow several machining accounts, but have never seen this tool until you started talking about it. Thanks for sharing. [edit] I can't even guess how handy this would have been for you when you were turning all those shafts back in the day.
Just a heads up. The bore needs to be indicated at the muzzle with a range rod before cutting the shoulder and threads. Cutting the threads while turning between centers risks a baffle strike with a can attached.
It's surprising how few machinists seem to know about face drivers and indeed how few people have ever noticed the witness marks in the ends of so many common production components. Face drivers were in use for wood turning for hundreds, if not thousands of years before metal turning came about. Simple designs just have fixed drive blades, whilst more sophistcated designs have mechanical or hydraulic means to equalise the pin pressure. Frank Ford has a page on his 'Frets' site on constructing a "drive centre", which is an alternative term for the device.
I guess a simple steel bar can't be turned into too many cool looking things and that's why he chose that recognizable shape to grab our attention while showing us his new tools.

@abom79 I have watched every video. Some of them more then once. I admit I am not the biggest fan of the promotion videos. Yet I accept that it is simply a fact of life for your channel now. Would it be too much to ask for a big project from time to time? Remember the welding table? Parking attachment? Etc? I for one love those types of content. It would still allow you to do the promotions but we would get something more from it as well. Anyway, best to you and Abby. 🍻
Hi Adam. Thanks for showcasing new tools/methods. I’m just a ‘hobby machinist’, but I really enjoy seeing the variety of machines, tools, Toolholding, and work holding you are using. From ‘old school’ to space age…. all good IMHO. Thanks again, Robert (Australia).
Other than push stop, start, and escape did you actually witness Abom performing any programing of the CNC lathe. Did he perform any programming at all for the camera, on any machine in the shop? Maybe rewatch the video?
Good to know about Riten repairing their own and other brands, I have a concentric live center that needs cleaned up and a Royal Live center that I could never get a response from Royal about rebuilding.
Royal does not repair or rebuild centers. Riten now makes the Concentric line and has for years. Remember, Concentrics must be lubricated unlike most other live centers.
Agreed was hoping for a traditional video. Not hating on CNC, I've watched many hours on Rotary SMP channel, but that's home shop scale not big budget loan equipment
We used face drivers 30+ years ago to turn rolls for printing presses. Any hardening and/or cylindrical grinding were secondary operations to turning. Some parts were finished in the lathe, others required the secondary operations. The face drivers we used required very little maintenance even in high production machining. I assume that the driver pins are hydraulic operated, the spring loaded center being the master cylinder supplying the pin loading pressure. This also ensures that the drive pins are evenly loaded even if the stock face squareness is not true. Our parts were much larger than Adam's so our drivers had more drive pins. I only had to do very infrequent drive pin and hydraulic circuit maintenance. The face driver was an enormous production efficiency producer, but created a prep step bottle neck. Our solution was to invest in 1960's technology by adding a G&L Endomatic. This is a length, facing and centering machine. This machine used two self centering workpiece vises to hold any size work piece. Two face milling heads mounted with centering drill heads finished the part to length and center drilled the turning centers to proper depth and on location. The Endomatic was the most geometrically complex machine for a maintenance man to set up that I have ever encountered. There is very little on the machine to reference from compared to a lathe or mill and multiple functions must be measured and compensated by finished part error. Adam didn't show us his prep steps, but I assume that he is forced to do those step tediously in his manual lathe(s). Or he will have to break his face driver set up. Indicating a face driver and or lathe chuck is counter productive to machining efficiency gained by the face driver. Prior to switching to face driver technology, we employed SMW air chucks and performed standard 2 step turning operations. SMW chucks were high maintenance compared to hydraulic chucks using a spindle mounted roating cylinder and draw tube to operate the chuck. The magic if the air chuck was an internal air operated pilot check valve that maintained chuck clamping pressure for the entire machining operation. OD mounted air sealing rings transmitted operating and clamping pressure then relaxed to provide free clearance so that the chuck could turn and not destroy the sealing rings. These were high production chucks and eliminated the through spindle diameter clearance loss yielded up to the hydraulic operated draw tube, but they were very high maintenance and tedious to repair and set up properly.
At Riten we make both mechanical and hydraulic face drivers. The one in the video is mechanical. Mechanical face drivers are more accurate than hydraulic, but hydraulic face divers are more forgiving in parts where the stock face is not perfectly square to the axis.
To the people at Riten, PLEASE use better colors for the color code; a lot of guys are red-green colorblind. How about dark red, lime green, and medium blue instead (i.e. bright, primary colors with lots of contrast.) I can barely make out the difference between the red and green there, even in good lighting conditions.
It's amazing how many companies don't understand that 8% of males won't be able to see these colors. Especially for a product that is primarily male oriented, and designed primarily by males. I had to fight this so many times in my job for LED, silkscreens and other UI design choices. I always got the 'stink eye' when I pointed out I couldn't tell certain indicators because they didn't want to spend the extra time to get the right colors.
@@charlieromeo7663 Color choices that are easy to see for everyone are well established. Web designers have charts specifically for this. For instance, traffic light green is a blueish-green that looks 0% like any red, and the red traffic light is a very saturated red. Basically, the sensitivity to red and green is reduced, so lighter shades of green and red seem similar, verging on gray.
Were you just making "demo" parts or is there a customer who wants those shafts for an application? If they're just demos, have you ever thought of selling those (with you logo stamped somewhere) to your viewers? Whether there is a use (alignment pin, clamping jig) or just desk art, it might be cool to have if the price is right.
We machined railroad axles downsizing them from a worn out larger size to the next size down. We tried a very expensive face driver and it just did not work out. The face driver had hydraulic driving pins on it and there was no way to set axles up repeatedly length wise in our CNC lathe. It turned out much easier with a good heavy six jaw set-true chuck. That chuck is the cats meow. Floor to floor was just as quick and no worry about having every axle in the same location length wise from axle to axle.
I've seen similar marks on the end of transmission and other high precision shafts over the years in the automobile industry. Never thought it was how the shaft was driven during manufacture.
Lots of demand for AR barrels. MK12 MOD0 barrels will be a snap in that rig! Think about this, the stresses imparted in the surrounding material of the barrel blank by the button forcing its way thru the bore during the rifling process is known to do strange things when you relieve those stresses by turning the outside diameter of a rifle barrel. Accuracy in a barrel has a lot to do with the way the projectile enters the barrel and how it exits the barrel. My concern would be the effect on the muzzle area of that barrel opening up if you are turning button rifled barrels, then cutting even more material away from the barrel right at the critical point of the projectiles exit. Add to that, the half-ton of pressure being applied to the end of the barrel by the tailstock, coupled with the addition of the 1/2-28 threads being cut and you compound the effect of the bore "possibly" opening up. Check on it yourself by pin gauging before and after the machining operation. Probably a moot point on an M4 length barrel (spray and pray) but if you cut barrels for Designated Marksman Rifles (DMR) it becomes a factor.
Great video, well explained. It is great to see your advances in the CNC technology and also different ways to hold and drive the parts. We all keep learning every day, or sometimes a refresh. I totally see the advantages of working with companies that make and produce products and parts you like; a lot of those items are expensive; and it is a win-win for all. I'm glad they see you as a means to get the word out instead of a flyer that helps nobody. I found the video a good balance between showing the product and your learning curve on the CNC.
VERY interesting to me Adam. I am one of those evil people who makes those bad black things....or at least works on them It was fascinating to me how to make those "drive pins with the threaded ends" on your cnc machine....REALLY cool! I also make about 15 passes for the 1/2x28 threads but it takes me awhile longer at 200rpm single pointing it!!! Thanks for the video really cool.
Love ya Adam, but this video is intended for a target audience. Not for me. But I really do appreciate you and all the content you’ve shared over the years. I really enjoy a lot of your older videos and I kinda think that much like the industry, your content is changing and adapting to new technology. I sincerely wish you the best. But this type of stuff misses the mark for me personally. My live center is from them. It’s a solid well built center. 👍🏻
It's exactly the same idea. Except that there is something (I wonder what?) that couples the three drive pins so they engage with equal pressure. With a wood drive dog the material is soft enough for that not to be necessary. I have an old one that uses rubber pads under the drive pins, but this one looks like it might be hydraulic. Though it could just be something like a hemispherical pad, I suppose.
I remember how much you enjoyed shooting with NYCCNC and you've got some experience casting. And now this.. is there an AR-15 complete build coming for Patreon supporters 😹
Would have been nice to get some TIR measurements in and out of the lathe. I actaully make drive chucks for our local plywood mill in various diameters and tooth patterns left and right hand. I just started doing the teeth on a cnc mill after many years of doing it manually and I love it. No more angle setups just let the machine do it all. Its amazing how fast and large they peel those logs and the core has a perfect star tooth pattern in the end from the dogs bitting in. Starts with 8" drive chucks and finishes with a 2-1/2" drive spindle running around 1,500 sfm!
Great video Adam! I really love your journey into the 'cnc-world" 3 Years ago i have taken the step into cnc machining and i love it! Now programming on a DMG-Mori lathe! Keep it up and keep the vids coming! Huge fan! Grtz from the Netherlands btw 🇳🇱
Adam. You have digressed from your earlier machining videos. They were informative, instructional and interesting. Lately, seems to be just one (long) product promotion after another.
Makes sense to me, they are still very informative and interesting. Just like you, I subscribed years ago when he did all manual. But going into new equipment to stay up with new technologies, it makes perfect sense what he's doing, specially if he gets a good deal on the technological advancements.
@@andrewterry8092 not sure about that, but the answer is very simple....if his content is not your cup of tea.......well....there you go. Good luck my friend!

Noooo, they're just your everyday hollow tube. UA-cam doesn't like pew pew content, not even mentions of it. They've been demonitizing channels for even holding them. So shhhhh!
@@cojones8518 I have watched dozens of UA-cam videos with firearms in them. None of them mentioned being demonetised🤷Seems like y’all are fear mongering to me.
BTW, love the GoPro shot from the top of the turkey assembly. Another interesting spot would be from under the turret, looking at the cutting action. Dunno if there's room to safely mount a camera under there, though.
Good to see you moving forward with some of the newer technology. Not ever being around CNC machines, do you have any indicating in you have to do prior to starting your work? (Yeah, I love to watch you do that on the Monarch) Love your videos!
Witness marks from face drivers have been common for as long as I can remember. This is s lightly different system though. Is there a minimum size of lathe it can be used on? I'm guessing it's too expensive for limited hobby use (I can count on the fingers of one foot how often I've needed to make a part in one piece) but could be really handy fo high volume CNC. Guess it depends on cost and availability compared to 'conventional' pressure turning systems, you can only use the patriotic, 'Made In USA' marketing for so long (look what happened to Harley Davidson, 500,000 motorcycles one year, now, Made In India)
I liked the old videos better where Adam explained how he was doing things and showed tips and tricks. even the grill videos were better than this stuff.
What does that pressure, combined with the machining forces, do to the spindle bearings? If you have to gronk on the tailstock handwheel that much it can’t be good, especially with harder materials.
Comment made before watching the entirety of it, but did anyone else see the steam wisps from the tail center? I'll look at the prior comments when I finish. MikeC edited for first wisp of steam at 24: or there abouts.
Because of the tight clearance of the bearing within the bearing housing, the live center does run "warm". That is to say you can lay your hand on it immediately after the spindle stops. Our lubrication is stable to temps up to 350 degrees F.
My concern would be the threads, you cant test them before taking the part out, and once the alignment to the spindle is off, you crossthread if you have to re-run those fine threads. Youd have to mark your witness marks 1, 2, 3, every part to check your threads and even then you might not get engaged properly. I understand you want to do it in one op... but i dont think i would do that with a threaded part.
With full profile thread insert, made for a specific threads per inch, one can measure the final outside thread diameter. If the diameter is about a 200 of an inch, say 0.1mm smaller than the nominal thread dia, then the thread is ok. In theory, but it always work for me. There are thread depth calculators to use, and lists.
Those shafts look familiar, especially the 1/2x28TPI on the end.
Interesting to see this in action - I've only seen it on wood previously. Surprised they don't supply a punch or press tool to create the driver grooves before the stock is loaded, to reduce the spindle load. That could create deeper (safer) grooves with less bearing stress.

1/2x28 threads, with that profile, I know what that “shaft” is for 😉. Is next week going to be how to bore a .224” hole down the center of it? 🙏🏻
No, it get's a 5-start, modified acme, .224-1/7 internal thread.

Does the pressure applied by the tailstock cause wear or damage to the bearings in the lathe?
Are you going to start selling barrels?
Nice ar barrel... 😄🇺🇸
I prefer tactile feel. Nothing more sensitive than your hands and body. Through experience, your dialed into pressure.
Adam. You have digressed from your earlier machining videos. They were informative, instructional and interesting. Lately, seems to be just one (long) product promotion after another.
Makes sense to me, they are still very informative and interesting. Just like you, I subscribed years ago when he did all manual. But going into new equipment to stay up with new technologies, it makes perfect sense what he's doing, specially if he gets a good deal on the technological advancements.
@@elchuco00 It might make sense to you, but the audience is dwindling, not growing. Not preferable.
@@andrewterry8092 He has more subscribers than ever!! What are you talking about?? Go away if free content and instruction bothers you that much!!
@@paulcopeland9035 Haha, you're still alive? I thought you were dead.
@@andrewterry8092 not sure about that, but the answer is very simple....if his content is not your cup of tea.......well....there you go. Good luck my friend!
Gutes Video. Viele Grüße aus Deutschland. Wo kann ich die mitlaufende Spitze bestellen?
Good video. Many greetings from Germany. Where can I order the live tip?
Those shafts look like rifle barrels
They are
Shhhhht 🤫🤫🤫 UA-cam super dumb about stuff like that, don’t get Adam a strike or this video demonetized
Noooo, they're just your everyday hollow tube. UA-cam doesn't like pew pew content, not even mentions of it. They've been demonitizing channels for even holding them. So shhhhh!
A test run for O.D. work. A real "shaft" would already have the I.D. cut before O.D. cutting.

I have watched dozens of UA-cam videos with firearms in them. None of them mentioned being demonetised🤷Seems like y’all are fear mongering to me.
Thanks Adam 👍👍👍
You can eliminate some reflection in your videos using a polarized filter.

Good stuff
Very informative video,Adam.Thank you.
This system has been around a long time. Usually found in grinding.
Great class!
Adam, I'm so glad that the CNC lathe is working out for you. It's quite a new world, this CNC, huh?
BTW, love the GoPro shot from the top of the turkey assembly. Another interesting spot would be from under the turret, looking at the cutting action. Dunno if there's room to safely mount a camera under there, though.
Good to see you moving forward with some of the newer technology. Not ever being around CNC machines, do you have any indicating in you have to do prior to starting your work? (Yeah, I love to watch you do that on the Monarch) Love your videos!
Face drivers are not _that_ new, we used them to make tensile-testing specimens back on the mid 1990s.
He said multiple times that they were only 'new to him' and knows they've existed in the industry for a while.
Did you watch the entire video? He mentioned the technology was nothing new almost as many times as he mentioned the MFR.
Witness marks from face drivers have been common for as long as I can remember.
This is s lightly different system though.
Is there a minimum size of lathe it can be used on?
I'm guessing it's too expensive for limited hobby use (I can count on the fingers of one foot how often I've needed to make a part in one piece) but could be really handy fo high volume CNC.
Guess it depends on cost and availability compared to 'conventional' pressure turning systems, you can only use the patriotic, 'Made In USA' marketing for so long (look what happened to Harley Davidson, 500,000 motorcycles one year, now, Made In India)
I liked the old videos better where Adam explained how he was doing things and showed tips and tricks. even the grill videos were better than this stuff.
Explaining would require understanding! Remember, this is "ABOM79 PRESENTS"!
Agreed once the CNC side came all changed, I started machining due to watching aboms video and tutorial side
That looked like an AR barrel, minus the bore...
nice
5:29 May The Force be with your... accessories.
That force gauge is easy to make if you can machine a precise 1 square-inch bore.
What does that pressure, combined with the machining forces, do to the spindle bearings? If you have to gronk on the tailstock handwheel that much it can’t be good, especially with harder materials.
Looks like a bunch of chips on the ways, there, Mr. Booth.
Comment made before watching the entirety of it, but did anyone else see the steam wisps from the tail center? I'll look at the prior comments when I finish. MikeC edited for first wisp of steam at 24: or there abouts.
Because of the tight clearance of the bearing within the bearing housing, the live center does run "warm". That is to say you can lay your hand on it immediately after the spindle stops. Our lubrication is stable to temps up to 350 degrees F.
@@KentHizer wonderful to know. Thanks
Where do you set your Z-zero and does it have to be reset after the pins dig deeper into the material after the first cut?
How do you bore it and rifle it?
I think they been using it for wood working.
My concern would be the threads, you cant test them before taking the part out, and once the alignment to the spindle is off, you crossthread if you have to re-run those fine threads. Youd have to mark your witness marks 1, 2, 3, every part to check your threads and even then you might not get engaged properly. I understand you want to do it in one op... but i dont think i would do that with a threaded part.
thread mics are a thing and the 3 wire method is also a thing .
With full profile thread insert, made for a specific threads per inch, one can measure the final outside thread diameter. If the diameter is about a 200 of an inch, say 0.1mm smaller than the nominal thread dia, then the thread is ok.
In theory, but it always work for me. There are thread depth calculators to use, and lists.
I am asking again. Where do you set your Z-zero and does it have to be reset after the pins dig deeper into the material after the first cut?
Good question. Probably not unless the dimensional tolerance is extremely critical.
