Please not to worry about episodic vs. full build - not on my behalf! I may be simple, but I enjoy spending time in your workshop, watching, learning and being entertained. If something takes more time, so be it! Really enjoyed this, the differential screw is so elegant and so is a Schaublin when programmed for a task :)
Thank you! Finally someone explained the difference between BT and SK tool holders. I’ve been searching everywhere and all the démentions seemed to be the same. I’ve been buying both on the internet for my Deckel FP 1. Both seem to work. I just had to change the length of the drawbar. The FP1 doesn’t have any alignment keys. Thanks for the video.
You have probably one of the most pleasant and quietest voice of english youtuber machinists. Of course, your vids are always a great pleasure to see and advertising. Keep on machining 👍🖖👌
Thanks for your kind feedback James. I notice a number of successful YTer are Canadian. probably helps to have an accent which is a bit exotic but but still understandable .)
For me, this is a first, As I am not a lathe worker, but interested. I like the fact that you tell me all the way what & why you are doing it. Thank you.
I would not call these parts simple. Quite a lot to go wrong there just like you mentioned with the CNC machines and the camera work at the same time also. I think you did an awesome job with these parts!
Great as always. You're constantly improving both the machines as well as refining your skills. I always look forward to your uploads, thanks for continuing to share with us. Don't feel a ton of pressure to put out a completed project each week. Stuff happens and if you keep that sort of pressure up you'll just burn yourself out. Remember this is all for fun 💜
I’ve found my diy cnc mill very usefull and have been thinking of building a cnc lathe. After watching this it just moved up on my to do list. My wallet thanks you.
I do enjoy your woodworking videos but I like the metal ones best. This one was particularly good. I couldn't work out the differential thread function until the reveal ay the end. Loved this project, thanks for sharing. - Heather
@@RotarySMP It's handy anywhere that you can't find room for a bolt head. I use one to hold the drive end onto the ballscrew of my milling machine Y axis, as there wasn't enough space to feed the screw in from the front or diagonally from the top. It had to drop in straight down.
Paulie: This is no f@ckin joke here, I could lose a foot. Christopher: Numb huh? Paulie: The f@ck you think? How could we be lost like this? We're in f@ckin New Jersey. Best episode!
Excellent and precise work, as usual! But wouldn't you have gotten better rigidity if you made a 40 cone with a flange and 6 screws to hold the boring head, instead of relying just on an M16 screw? Obviously there is also a 30 mm boss, but ultimately the M16 screw part is the weakest link in the "chain". The boring head is quite large and heavy.
It is not an M16 screw, one end is M24x 2.5 and the other is M28x1.5 Since Wohlhaupter uses an M16 screw on their UPA 4, which is the same size, I have no doubt of the ablity of this design. The six screw holes are under the taper, so to use then requires an intermediate flange. That adds height, and would have required turning the arbor and intermediate flanges out of 110mm stock, rather than the 65mm I used. Would have created a huge waste of chips.
@@RotarySMP You're right, it's my fault, I wasn't paying attention and got lost in the technical details. What stuck in my head was your struggle with the long drill bit... The flange brought height of about 15 mm maximum maybe, but turning the shaft and the flange from a single piece increased the rigidity and concentricity, in my opinion. It's true that a lot of chipping is created in the turning process from a bigger stock, but hey, it's done for a hobby and maybe once in a lifetime :) Anyway, I admire you and I want to congratulate you for the complex and precise work you do. Keep up the good work !
@@narcism2672 I am glad you enjoyed it. Given that Narex went to the effort to design it with that flange, you are probably right that the ultimate rigidity is higher, but I will never run this to it's limits.
Wonderful video, showing the CNC process, warts and all. 👍 One of the things I discovered with my own CNC journey, that often, by the time you do the CAD/CAM work on the computer, sort out the tools and tool changes, re-iterate a bit to tweak stuff and get the machine to cut the part... It works out that just manually making that part would have been quicker and easier. Of course, the REAL value of the CNC process is when you have to make more than one of the same part! And also if the part has some complex features like splines or gear teeth. Thanks for sharing, your channel has become really polished and enjoyable. 👍 Even the music, the subtle hip hop beats etc, tasteful and well placed. 🥰
Yeah, I am really slow on my Schaublin. I am simply not spending enough hours on the tool to be really confident of which feeds and speeds, tool stick outs etc will work reliably. On a manual, much of this is sort of intuition and feed, but the G code wants numbers and follows your errors slavishly :)
Could you pull the bezel from the control panel and just file the edge of the screen cutout so that the metal comes to a 45 degree angle for your fingers to touch the screen?
No better start for a lazy sunday. Watching the Schaublin cutting tapers is hard to beat 🎉. I think there is a white plastic spacer on the center finder you need to remove to give it it’s full range of motion. That boring head really looks nice on the maho.
@@RotarySMP ……… I just know it because mine fell off and I desperately tried to reattach it for several days until I figured out it’s a useless piece of plastic😁 so same same but different🙈
Just a safety tip, don't leave loose keys and tools on your lathe. That T key on the tool post will end up being knocked into the moving chuck at the most inopportune time. I know it's easy to just leave it, and a lot of people do leave them like that, but it's just disaster waiting to happen.
I only got a quick glance. I might be wrong. But I think Christian sent you a 15mm high feed mill. These are my favorite tools. I don’t recall you using them on the channel. I’d love an episode of you high feed milling. If it’s lnmu0303, your max step down is .032” but they run at 650sfm and .03” feed. They are great for roughing and drilling big holes.
I am not sure the little Maho can even move that fast, and i would probably chicken out :). That is not very practical for single parts like I do. In production, you can keep optimising to max out the capacity of tools, for one off, you have to be more conservative.
@@RotarySMP oh! The travels on the maho probably won’t get there. But don’t write off the one off use of those tools. You were short on time this very episode! High feed mills are fast and efficient. They also have the benefit of pushing down much more than laterally. So you can use long tools without rub or chatter issues. It takes a little getting used to, but very cool. It’s not really production vs one off. I use them all the time for single pieces. It’s about CNC vs manual. It takes a lot of passes! Love the channel. Thanks for doing it!
Excellent treat for me! :D Love the differential thread solution, I would have not thought about that. Awesome boring head, I need one for my Syil X7 too although it might be huge for my machine :D
Your list is getting pretty scarce there my friend ! 😊 I lived this one ! The music, the editing, the content, the failures, and the success’s ! All the way around good. This one is a 360* double thumbs up 👍🏻👍🏻 🫡
Have you had any problems with this dro? I recently fitted one to my lathe. I set the compensation value to 2 on my X axis so it reads the diameter not the radius so no calculator. Seems to work ok for my use.
I have a Vhu 1-3/8" boring head over in the U.S. Mine has a bolt on a R8 taper for a Bridgeport milling machine. Mine came with a case with a bunch of attchments & paper work. I haven't used it because I'm not sure how to. I spent a little time a while back reading the paper work & looking for youtube videos on it. I didn't find much on the subject. If you figure that tool out, I'd love to see a video on how to use it properly. Good luck with that tool. It looks like a quality tool.
@@RotarySMP Yes. It looks like a beautiful mechanism. I'd love to get good at using it. Just like anything else, I just have to put the time into it. Thanks
Really cool project. I do fancy a cnc lathe to do 2 stroke cylinder heads but I really like just being able to do things quick on my manual lathe. I guess I need both 😅
Love that differential thread. Is there any chance the thread could loosen with spindle rotation? Would clockwise or anticlockwise be the better direction to stop in loosening. I don't think it would, except in heavy chatter/ vibration.
There is no rotational force on the screw in service, as the key locks the shank to the body in rotation. If the key were loose (it is not) it could theoretically vibrate the screw loose.
Hey Mark, great content as always :) Question for you, have you done anything to make your linuxcnc machine boot faster? A fairly large annoyance for me is that my machine takes nearly 5 minutes to start up, and then another minute or so to actually load in to linuxcnc (I am using very old dell optiplex machine). It's enough to make me not look forward to using the machine, so I'm starting to try and figure out ways to improve it, hopefully without needing to just spring for a new machine!
My three machines - The Maho has some old PC MoBo, and boots medium slow, the Mini-Lathe has a Gigabyte NUC and is really, really slow to boot. The Schaublin got a HP Elitedesk mini G2, with an i5 in it, and it boots way faster. About 20 seconds and another 5 for LinuxCNC.
You run down a rabbit hole of learning some program I dont know, changing all sorts of thinks to save on buying a €5 stylus which solved the problem? 😬
@@maximelenfer6280 They came in a three pack :) But yeah, I did put it in the wrong place a couple of times, and had to look for it. It would take probably 50 Hours work to strip down that display and bevel it. I simply dont have time for it.
After getting to the end of the video that became painfully clear when I saw that the slots were cut 90° offset from each other rather than inline like I had been envisioning at the beginning in my head. I apologize for the unnecessary question and appreciate you taking a moment to respond. Best to comment with Questions AFTER you watch the whole thing. 😅
@@RotarySMP It's clear at the end... Interesting! At a tischlerei where I worked, there were signs at the werkbanken that read "ich bin schuld" ... I found it strange until the boss can into the shop because there was a screw up and he asked "who did that?"
Спасибо, очень познавательно (Russian, from St.-Petersburg) = Thanks for the video. I learned a lot of new and interesting things. I subscribed to your channel.
@@RotarySMP okay was only woundering if it had it but then agen then they would also had been so far ahead of big kaiser ( they have a internal rack and penion to move a internal counter weight )
If that was WD-40 you used a couple of times, you might save some money by buying a large can of it that you can spray into a squirt-bottle. You can even get WD-40 squirt-bottles -- I ASSuME that their bottles last a long time before breaking down from chemical incompatibilities. Thumbs up!
I saw Calexico last year in the Volkstheater and now in Tulln. I thought they played well, but didn't put the set together well. It seemed each time they got the crowd rocking, they either started talking, or played a slow intro, and lost momentum. And yeah, too short. Marina and the Kats were one of the best opening acts I have seen since we saw Muse open for Live in the late 90's.
Yeah right. I saw them for the 7th or 8th time. I think the set was nice but the mood was strange. Last time we were dancing in the water in front of the stage, nothing like this this time. And you are right, great opener. It felt, at least a third of the audience came just for seeing them and left afterwards. And an other third was bike tourists randomly getting a ticket 😂 Imagine, Muse being an opener 😮
@@mazchen It was wild, they were very young back then, but were sounding huge for a three piece. We kind of knew immediately that they were going places. I think it is really nice how appreciative Calexico is of the audience, and also really nice that the always involve the starting act back in to the main show, but sometimes it is time to shut up and sing :)
Re: the poor finish from your brazed carbide threading tool. In the world of woodworking handtools, where a sharp tool makes the work go easy, and have a good finish, it is stated that a sharp edge is the intersection of two polished planes. In your grinding, you carefully worked the 2 lateral sides of the tool, but the finish on the top surface did not seem particularly good, and you didn't grind it. So I wouldn't consider the edges sharp. Could this explain the slightly disappointing results?
At minute 17. If you want to do a radius with the Grove tool you should be able to copy the code from your front turn and edit x and z. Should be something like- G0 x1.2 Z-1.3 G1 x.805 G0 x1.2 Z-1.1 G1 x.805 G0x1.2 Z-1.0 G1 x.83 G3 x.8 z-1.03 r.03 G1 z-1.3 X1.2
@RotarySMP you can as long as depth of cut is only a few thousandths and slow feed. Maybe .002 ipm. Plunge staight in like a normal groove Tool then a finishing pass like a turn tool at only .002 or .003 depth of cut
My! what an adventure, and succesfull week (edit ,needed a few minutes of research) perhaps something like this tool would be a helpfull addition for that close to the chuck work.
ISCAR HELIR/L : External Holders for Turning, Grooving and Parting
Hi Steve, you can go super close to the chuck, as the lathe will position within a few microns, but that feeling of actually having everything programmed right, and a good verification methodology, cant be replaced with tool holder geometry.
@@RotarySMP about once a month for about 14 years I traveled to customers shops to correct the result of getting those few microns wrong, I know what you mean😱 Although more than a few of those crashes were caused by workholding failures. the HELIR and similar tools are also very useful for all sorts of work because they are not "handed" in the usual sense, they can groove both left and right as well as part.
I hope the missus never does the math on how you got these machines just to make more parts for the machines and future machines you may want to purchase. I personally find nothing wrong with it and suffer from the same affliction. I’m also single so I don’t have a bean counter to worry about.
You should spice things up and make some metal handles for that desk you built. That will allow you to have something to point to when it comes up again.
Thats a nice boring head - The diff trhead taper shank is a very elegant solution and nicely executed!

The motion is more obvious when mounted in a mill, so you can see it gyrate around. Also Inheritance machining has a really good video on it.
@@RotarySMP Yep ,I've watched your video on it and others but it still gets my mind every time.
@@kenthesparky178 It worked really well on this hex. On squares I keep blowing the tool apart.
Is there some reason you couldn’t remove the “keys” and reattach them after you fully screwed in the 40 taper?
yes. The key retention screw is under the taper shank.
After getting to the end of the video that became painfully clear when I saw that the slots were cut 90° offset from each other rather than inline like I had been envisioning at the beginning in my head. I apologize for the unnecessary question and appreciate you taking a moment to respond.
Best to comment with Questions AFTER you watch the whole thing. 😅
You can do a radius with the grooving tool.
True, but I was in a hurry and would have needed to program that.
??? "14mm hole, which is clearance for M16??? 😊
Core drill size?
Auf und Zu? Ach! Wie ein Klapstuhl!
3:07 Is it possible to remove the keys? Then put them back after the mount is in place?
Ja habe ich auch nicht verstanden, warum das engraviert worde.
How would that work, the way they are screwed to retain them ?
@@RotarySMP It's clear at the end... Interesting!
At a tischlerei where I worked, there were signs at the werkbanken that read "ich bin schuld" ... I found it strange until the boss can into the shop because there was a screw up and he asked "who did that?"
@@Johannes58934 I had not encountered those differential screws before, but they are a handy solution for some problems.
Which material do you use for these two parts?
It is in the video Stefan.

@@RotarySMP Thanks, I found it.
Спасибо, очень познавательно (Russian, from St.-Petersburg) = Thanks for the video. I learned a lot of new and interesting things. I subscribed to your channel.
Glad it was helpful!
Question is. Does it also have a counter weight inside it to balance ?
No, the manual recommends an RPM limit of 500, as it is a large and often imbalanced lump.
@@RotarySMP okay was only woundering if it had it
but then agen then they would also had been so far ahead of big kaiser ( they have a internal rack and penion to move a internal counter weight )
@@flikflak24 Big Kaiser makes nice stuff.
@@RotarySMP agree. even though i only used there stuff ones ( the micro boring head "big kaiser ewn 04-7" ) it was really nice
If that was WD-40 you used a couple of times, you might save some money by buying a large can of it that you can spray into a squirt-bottle. You can even get WD-40 squirt-bottles -- I ASSuME that their bottles last a long time before breaking down from chemical incompatibilities. Thumbs up!
This was a specific cutting oil. I only use WD-40 as cutting oil on aluminium.
6:52 cool! How did you like Calexico? I think the Tulln gig was a bit short.... or is your shirt actually telling the truth?
I saw Calexico last year in the Volkstheater and now in Tulln. I thought they played well, but didn't put the set together well. It seemed each time they got the crowd rocking, they either started talking, or played a slow intro, and lost momentum. And yeah, too short. Marina and the Kats were one of the best opening acts I have seen since we saw Muse open for Live in the late 90's.
Yeah right. I saw them for the 7th or 8th time. I think the set was nice but the mood was strange. Last time we were dancing in the water in front of the stage, nothing like this this time. And you are right, great opener. It felt, at least a third of the audience came just for seeing them and left afterwards. And an other third was bike tourists randomly getting a ticket 😂
Imagine, Muse being an opener 😮
@@mazchen It was wild, they were very young back then, but were sounding huge for a three piece. We kind of knew immediately that they were going places.
I think it is really nice how appreciative Calexico is of the audience, and also really nice that the always involve the starting act back in to the main show, but sometimes it is time to shut up and sing :)
SK has two diferent width slots. On one with the notch it is as on BT40, and narrow one on the opposite
Oh, I just measured one. Thanks.
@@RotarySMP You are welcome.
WOW
Thanks.
Re: the poor finish from your brazed carbide threading tool.
In the world of woodworking handtools, where a sharp tool makes the work go easy, and have a good finish, it is stated that a sharp edge is the intersection of two polished planes.
In your grinding, you carefully worked the 2 lateral sides of the tool, but the finish on the top surface did not seem particularly good, and you didn't grind it. So I wouldn't consider the edges sharp.
Could this explain the slightly disappointing results?
Good point Paul. That would also explain the better results from the inserts, as they are ground with similar geometry, but more fine finish.
At minute 17. If you want to do a radius with the Grove tool you should be able to copy the code from your front turn and edit x and z. Should be something like-
G0 x1.2
Z-1.3
G1 x.805
G0 x1.2
Z-1.1
G1 x.805
G0x1.2
Z-1.0
G1 x.83
G3 x.8 z-1.03 r.03
G1 z-1.3
X1.2
Sure, but that parting tool is new to me, and I didn't have any experience on using it to turn sideways.
@RotarySMP you can as long as depth of cut is only a few thousandths and slow feed. Maybe .002 ipm. Plunge staight in like a normal groove Tool then a finishing pass like a turn tool at only .002 or .003 depth of cut
@@aarondeck2814 Thanks. I need to try that.
My! what an adventure, and succesfull week
(edit ,needed a few minutes of research)
perhaps something like this tool would be a helpfull addition
for that close to the chuck work.
ISCAR HELIR/L : External Holders for Turning, Grooving and Parting
Hi Steve, you can go super close to the chuck, as the lathe will position within a few microns, but that feeling of actually having everything programmed right, and a good verification methodology, cant be replaced with tool holder geometry.
@@RotarySMP about once a month for about 14 years I traveled to customers shops to correct the result
of getting those few microns wrong, I know what you mean😱
Although more than a few of those crashes were caused by workholding failures.
the HELIR and similar tools are also very useful for all sorts of work because they are not "handed" in the usual
sense, they can groove both left and right as well as part.
@@steveggca Knowing me, I would probably crash the Helir, on its maiden voyage, just like Captain Smith :)
Another week to be jealous of your machines and skills 😂
Thanks for your kind feedback.
Without context, how would anyone know if you are talking about an arbor or 1970s Swedish pop group?
That happens a lot :)
get some "craytex" for cleaning up the threads
Thanks for the tip.
4:46 - it is not a good practice to grind a regular steel on a diamond wheel. (tool body is a regular tool steel)
Yes, but you dont have a lot of option with brazed carbide, and diamond wheels are pretty cheap now.
Arghh Mark's been infected with the Artisan Makes hacksaw virus! 😀
At least until I fix the Do-All gearbox again.
I hope the missus never does the math on how you got these machines just to make more parts for the machines and future machines you may want to purchase. I personally find nothing wrong with it and suffer from the same affliction. I’m also single so I don’t have a bean counter to worry about.
Did you see the video of my wife giving my sister a tour of my shop. Your concerns came up 🤫
You should spice things up and make some metal handles for that desk you built. That will allow you to have something to point to when it comes up again.
@@jdmorgan82 It got metal handles, but from Ikea. :)

Sorry Mark but you’re an aircraft maintenance inspector and “it’ll do “ isn’t something I want to hear from you !
Hi Andrew, come on, nearly all the doors were installed. :)
@@RotarySMP yes, ‘nearly “ is something else I don’t want to hear lol
We ‘nearly’ got to the airport but made it to the crash site
@@andrewclark8225 Yeah, but it did FLY all the way to the crash site ...
Write up: "#1 main wheel nearly worn to limit"

I have a band saw... a Do-all 16" :)
