You can say that over and over about Stefan's videos. I mean, whenever I try to have a quick glimpse at them, I always end up watching them a-z, if not even re-watch, in some parts just to make sure I've got it. His vids are as bemusing as their contents are.

Doubt if this is something I would ever use, yet interesting to know one can do it. Please thank your client for allowing you to share your work!

Not a machinist (lowly wood world) but gosh its mind blowing the tool cuts with the edge break. I would have thought that would have blunted the tool instantly. That was super cool. I too am a fan of the long format (though I shouldnt spend so much time on youtube). Really cool video all around. So much learning even from a wood perspective.

Mark ... google "negative rake cutting" for a complete explanation... the tool does not actually cut on the "edge" but inland... completely unintuitive !!! 😎👍☘️

Stef, thanks for investing your time in these wonderfully educational videos.

Now I have two great sayings from you: "looks like it was cut with a dull beaver" and "slow as continental drift" :D

Excellent video Stefan. I plan to put that CBN repurposing to use. for the kind of work job shops do it seems like a must know. Especially with the cost of new . Thanks and thumbs up

I clicked on this channel by mistake I started watching waiting for the show to start to see what I clicked on but this started and I was hooked right from go so I watched all the way through and I am so glad I did it’s amazing how a simple wrong touch of a finger can result in such an awesome outcome thanks for the video I can’t wait to see some more of your channel

Been watching from the beginning. Consistent good tips. I have learned a lot from this channel.

Interesting how you narrow down the possibilities to get the fit you want. Maintaining control all the time.Next time I do anything' I'll reflect back to this lesson

Right up my alley. I built an automated, multi stage, hydraulic swaging press this year that used belleville washers as force gauge/regulators on each station. I thought I was so clever but I guess there is nothing new under the sun. They pack a lot of force into a very small space. The CBN information is really useful, thanks.

Most excellent techniques to have in the home machinist toolbox👍 I really enjoyed the longer video also👌👊🏻 Thanks for your efforts💯

Amazing as always Stefan

The time before I asked for more advanced machining lessons, and I got a 50min super class. Thanks Stefan!

As always, thanks for the lessons !

many thanks for the demo Stefan!

So if you have the good fortune (?) of having a workshop on a fault line, you can attach your lathe bed to one tectonic plate, your carriage to the other plate, and hey! free carriage feed! ...with the occasional, unpredictable roughing operation!

If you take the median of 0.018-0.180 μm/min, you get 0.090 μm/min, which is 47 mm/yr (4.7 cm/yr). With your range, of 0.018-0.180 μm/min, it's 9.5 mm/yr to 94.5 mm/yr.

Excellent precision video Stefan. May your Atoms never be at rest🤔

Another fascinating video! Thanks Stefan. I took note of your tip in an earlier video of sharpening carbide inserts using a diamond hone - I'd given up trying to use them on my small lathe, but now they cut like a dream! Cheers :)

Great video sir! This level of turning is way beyond my old Atlas lathe! I'm just proud to now know what CBN is.

I loved the hell out of this video. I discovered CBN and Cermet inserts recently and am getting somewhat obsessed with them. This just pushed me over the edge. I accidentally trashed a CCMT CBN insert and am about to order some diamond wheels now that I know I can touch them up and get more use. Awesome vid Gottes!!

Excellent as always :)

thanks for the valuable information you share. good filming work also

Hi Stefan, Great video. The the idea of running CNB at high speeds is to cause enough heat before the tip to anneal the surface a little. We run at 500 sfm most of the time but we run the feed rate slower than recommended to achieve a better finish. We have had great success using CBN and love it. Steve

Good stuff as always Stefan. People on You Tube seldom talk about a cutting edge chamfer on tools. They usually talk about getting them honed sharp. I chamfer regular brazed C-6 Carbide tool bits to rough out welded bores that always have interruptions doing construction equipment repair using my portable boring bar. It helps to keep them from shattering. The construction of your CBN tools was very interesting. Cheers

C-B-N,C-B-N! Thank you Stefan, really appreciate you sharing your tricks on the dark art of cbn tooling. Even just sharing the angles you grind to saves the rest of us many, many hours of trial and error. I can stop holding my breath for this video now. Cheers Jaime Moneyvsmachines

Stefan Gotteswinter those folks would be on a level of machining that I’m not even sure I could enjoy. I suppose due to your modesty, us 200lbs gorilla hobby machinists, can still enjoy. And also build a few of your projects. I built your parallel comparator/surface gauge you made a while ago. Turned out very well, except for the ball bearing feet. I could not get them loc-tited in and grind them without heating them up.

I’m struggling to imagine a higher degree of precision than yours and why that would be needed. OK, so the 1 micron diamond paste was too fine and you switched to 3.5 micron paste to speed things up, but geeze! (BTW, looking forward to seeing what those bushings and rollers are for given the care and precision. I know you said you can’t reveal the product but I’m guessing this is not a tubing bender!)

haven't watched till the end, but the talk about ceramic lapping discs got me thinking - turn an aluminum blank, load it up with diamond slurry/paste, anodize it (perhaps hard anodize), hope that the diamonds don't fall off while the anodizing is forming - and one just might end up with a usable ceramic/diamond lapping wheel, normal room temperature anodizing I do every day at my shop, but hard anodizing would be trickier and time consuming to set up, but I've done it before, just need to find time for a project like this, that is the biggest problem...

Beautiful work. I wish I could do that kind of work.

Ugly tooling that works really well tends to develop it's own special beauty.

Stefan, really interesting video thanks for sharing. What grit diamond wheels were you using to hone the insert?

Waaaaaaaay gooood enough!!!$ like it.

Hi Mate , I had to do some lapping on my last video & lapped a hardened spindle for my grinding attachment but could only get a dull finish using 14 micron diamond lapping paste , could this be related to using 46 hyd oil as a lubricant instead of WD40 Robin R mentioned the diamond particles can roll around instead of embedding into the lap if there is not enough tension on the lap . Have you come across this issue before ?

I like watching your work. What type of torch was that you were using. Very cool.

Excellent. Now i'm off to find some CBN.

Realy interesting with lots of info about hard turning, thanks a lot, beware of cosine error when messuring with a test indicator ( I use the cosine error to my advantage when using my Interapid in inch when messuring in metric )Are the disk springs made to order and from whom, I know of another youtuber PeterBjork ( he is as meticulous as you !! :-) ) that need a large one for a Lambo clutch.

tony!!? hey old tony!! You see this.. its very nice..

Those tooling marks on the bored parts look quite deep. Is that an illusion because the material is so reflective? Are the marks actually just a couple of microns? I'm ecstatic if I can get within a thou! I think this is one of your best videos ever. So much knowledge packed in. This is a subject that most of us hobby guys have no families with.
