Hey, as a Swiss national in his early 30's doing an apprenticeship in the field, and having a few years of experience in machining, ( mostly production [ button pusher ] but not only ) and being very passionnate and interested in the field. I just wanted to say that i found your videos very resourceful and interesting. I wish they would be more frequent, but really your 2 euros of expertise on everything, is just too good. Learning from you, Renzetti, Lipton, Peter Stanton, Joe Pie, is just too good. I'm very glad that RUclips offers a plateform for such incredible individuals.
A trick i saw from Robin Rinzetti was to put an O-ring arround the drill when pecking. It moves back when feeding in, so when going back in you have an indicator to rapid towards to you dont ram tour drill into the bottom of the hole
Great idea, & I have used a small piece of bent sheet aluminum set on the vee way to do this as well.. especially good when reaming deep holes.. & on the Burke Millrite, there is a spindle depth indicator and you can put a small magnet in front of the indicator so it is pushed down by the indicator but stays in place when the spindle is retracted.
That's brilliant. Not that I'd expect anything less from R.R.
Great Idea!
That is one of those ideas where you think, "Why have I never thought of that?"
No matter how long you do something, there are always these simple tricks or hacks that you learn from others.
Sharing knowledge and learning is the 'best' part of the internet.
"It's just a Dremel that doesn't suck." HAHAHAHA
Your videos always demonstrate how lathe and milling cuts should sound and what I should be listening for. I just love those silent slices!
Except that rounded parting tool. I'm glad he added it as the chatter gremlin can happen to anyone.
I really appreciate the explanations you provide. Explaining that chips building up under a drill can cause the drill to wander is a great tip. Explaining that you are deburring an edge we know you're going to cut off because the burrs could change your measurements is a great tip. The carbide tool in the bore to add rigidity is a pretty damn good tip, too.
I think details like this are probably second nature for you, so choosing to explain them is impressive presence of mind. "What am I doing and why am I doing it?". It is always a joy to watch and listen to you work.
That high magnification shot is awesome!
Stefan, pro tip: I usually use a +1 sized box wrench to round the edges of the hex.
😵💫
😂
I've only seen 15 minutes of the video, and I enjoyed every second of it. I like the excellent video quality and the detailed explanations, but I particularly find the "working in real time", including the sounds, really interesting and instructive.
Thank goodness you quit your full-time job, because now there are many more videos in even better quality. :)
Keep up the good work!
wow that was my first Stefan project, I was captivated for 40 minutes, even at normal playback speed. great work, thanks for sharing
31:34 whoa. I thought scent was the sense most linked to memory, but it turns out that seeing the exact same TI-84+ you used in school is the most powerful.
Haha, can you imagine how many people have that link to memory for a TI-84?
@@Hoaxer51 I agree about olfactory sense-related memory, and I’ll never forget that wonderful new electronic/plastic smell you used to get. For me, the images trigger my memory of the scent and vice versa.
I had the HP28C, which became an appendage. I never see them on RUclips. Once I had mastered RPN (Reverse Polish Notation) on those HP calculators, I was so, so fast. When I got my engineering degree, any calculator with a multi-line display was a game changer, but using SWAP, ROLL, DROP, and the ability to have named variable or numeric values instead of being restricted to just a memory key on other calculators was/is so lovely. The built-in CAS (calculator algebraic system), along with the option to get exact or numeric answers, is just so perfect.
Flat screens used for data entry on our smartphones make me long for those incredible chunky hard plastic keys, the firm pressure needed, and the feedback you got. The firm depress on those keys let you know you had entered a value.
@@marclevitt8191 Touch screens are cheaper and they are putting them in cars in place of knobs, buttons and levers. Pain in the butt because you have to take your eyes off the road (no feel).
Very nice work as always Stefan!
ATB, Robin
Thank you Robin!
Very nice. I appreciate your low tech solution to protecting trade secrets like your reaming operation.
Attention to detail and pride in work sorts the men from the boys. Excellent example of true craftsmanship.
Interesting device. It is very reminiscent of an injection quill, used to inject chemicals into a stream flowing in a pipe. These are typically and simply made by taking a thermowell and cutting the end off at 45 degrees. A thermowell is a device used with a thermocouple to measure temperature through a pressure envelope; they are typically made of 300-series SS. They thread externally into the pressure envelope, usually with an NPT connection, and the thermocouple (or RTD, if you want to split hairs) threads into the internal cavity, also usually with a smaller NPT connection. Thermowells are a commodity item, produced in large batches on CNC lathes, and are very cheap, only fractionally above the cost of an equivalent weight of pipe. Back in my shop days we would cut off the ends of the thermowells with a bandsaw. Sometimes that was good enough. If not, we would mill the end to the angle required, which was 45 degrees 99% of the time. Once in a while, we would bore the end and tap it for a precision orifice, which could also be bought for literally pennies.
It is very interesting to see the machining steps to arrive at a similar device, and it's good to see that your client was unable to use a thermowell, and had to engage you to build his bioreactor entrance port!
Good tips, thanks!
A fan of your channel for a long time. And to be honest, I learned more from you than at university.))) Thank you for sharing your knowledge, it is priceless. And great video as always.
Turning the rounded edge with the milling tool is something I'll keep in mind! :) Leaving the key in the chuck will always make me nervous, even if it's only for a short moment (not that I wouldn't do it..) - a fear that was practically implanted into us during the apprenticeship.
Ah, bioreactor + flux capacitor = flying Time Machine 😁
The EMCO made many parts for you. I do hope it is happy in the new shop. 😁
Thank you for an informative video, and thank your customer for allowing us to watch you make the parts!
Awesome project.
As a fermenter user (same as bioreactor, just for yeast and bacteria, not cells) - wonderfully crafted connectors :)
When I heard the spindle VFD, I realized this part was made on the emco, I thought you added a VFD on the new Weiler.
Nice part! Thanks for sharing!
The weiler will most likely not get a VFD :-)
Yes I noticed that too, the silky smooth sounding Emco.
Also noticed the solid tool post, and thought that Stefan said he wasn’t gona install one.
Absolutely beautiful closeups!!
very good job stefan..thanks for your time
11:39 this shot is so stunning. Perfect focus and composition, and I’m loving whatever lens you used.
Enjoyed…great discussion/demostration/build
Great video Stefan and a lovely looking part. I especially liked the use of the mini belt sander for de-burring. I've had the Proxxon equivalent sat in my drawer unused for the last two years and not once did it occur to me to use it for de-burring parts. It'll be getting a lot more use from now on!
Thank you for the very full explanation of everything.
Such good looking parts, fantastic work.
Nice and superfine work!
Beautiful work. Love the egg box packaging at the end. Thanks for your time and skills.
Nice work. My dad was a machinist. He made special surgical instruments and tools. I can appreciate the high caliber of work. Ty
that thread relief cutting sound. scary.
nice video !!! nice macro lens !!!!
Yeah, it sounded like he used some of that "whale oil" by accident instead of cutting oil😉
@@2lefThumbs I'm not sure if you're joking or not. "whale oil" is "way oil", a high-viscosity, tacky oil designed to lubricate machine ways.
@@DuncanKBurke thanks for giving me the benefit of the doubt👍
I was definitely *trying* to joke 🤣 : a few years ago, Stefan mentioned the use of way oil, and got some flak from people who tought he said ""whale oil", I was referring back to that👍
That chatter genuinely *did * sound like whale song to me though, hence my comment😂
Lovely work Stefan, thank you for the lesson. I saw this posted last night but I needed to make time to savour it today! Loving the macro shots too, really useful to see exactly what's happening. Lacking a little in contrast on the macro, but very good angles. Always learning here.
Beautiful work!
Interesting and informative as always.
Thank you Stefan.
Best wishes to you and your family.
Excellent work,Great tools.Thank you.
Always something to learn from you Mr Stefan
Did enjoy it, thanks for sharing!
Always a pleasure to see your work flow Stefan! Would you consider a video on pricing small run parts like these? It would be interesting to know what these parts cost, to make them worth your while.
Thank you so much for sharing these with great explanations.
Another Stefan Gotteswinter masterclass. Thank you!
Beautiful parts!
Nice job, well done.
I sometimes use a feeler gauge instead of bumping the tool into the part. It works well with parting blades which flex.
Nice one . That grooving tool may behave better if flipped upside down , but i guess you will be using the new lathe now ! Cheers 👍
Most things are easy when you know how, and hard if you don't. Some of these "simple" tricks are VERY handy for us that aren't already experts. I know how to chamger nuts, but I learned it somewhere in the RUclips world.
Great video as always Stefan! 👍👍
That little belt grinder is sweet bet it makes finishing a breeze.
I used to use these 40 years ago, we used to flame them in those day. The idea is that there is a silicon septum in the reactor and the spike pierces it to keep a hermetic seal.
I’m no longer in that field but I thought that more elegant engineering solutions had been developed decades ago, but perhaps this is for a non critical application.
I find that my little 1” stationary belt sander is quite handy for a lot of de-burring as well.
I learned a lot from that. Thanks!!!
I believe it was the shaft sticking out that was reinforcing the resonance during the thread relief cut. I bet if you let a lead faced hammer contact the end of the shaft (just resting on it) while turning it will cancel the harmonic. I could be wrong of course, but I remember having to make several parts with similar shape and was getting a horrific droning chatter like that while parting. The lead stopped virtually all of it.
Thats very likely, agree - Its sometimes funny how resonances can mess with an entire rigid appearing setup.
I have the same experience with rounded grooving inserts, they tend to chatter worse than regular parting tools. It can help to walk the tool a little sideways similar to reducing chatter from a large form tool.
@22:31 I use morse taper inside the spindle for back stop. I have morse shank with thread, to change different diameter and length bar for stop. I also face cut them if the engagement to chuck jaws is short.
Excellent- thanks.
Nice Enjoyed 👍👍
Would have loved one of those Belt files when I was doing a lot of cleanup of castings. We had a really old Makita one that would snap through the splice on the belts almost daily.
Nice job . I once made a jam nut , chamfering both ends at 45° and almost no hex left 😂😂. So form me 60 degree included angle tool is the way to go
That never ever happened to me before, haha :D
Nice closeup shots during machining!
richtig sexy sowas! Der Fräser als Dünnwand Verstärkung einzusetzen ist richtig nett ^^
It's just a Dremel that doesn't suck 🤣
37:30
Stefan, consider your outro credits. We're approaching half April '24
One of the few channels i watch at normal speed, almost all others it's x1.5 or x2. Lifes tò short to watch some at intended speed.
Good Morning Stefan, the misbehavior of that form tool seems so familiar to me 🤔
Nice project! 👍
Hey I actually also made some of these for a customer ha! Cool to see. Would be interesting to see if it is the same customer.
"Like any civilized person I drill with the carriage..." quote of the month right there!
no run out detected "thats a fine amount of run out"
I see you are back to solid toolpost. EDIT: OOOPS that was the old lathe. Sorry.
It's so soothing to watch your attention to detail as the part takes shape! Were the hex faces and/or the bevel timed to the threads?
The latest generations of valve seat milling machines in the automotive industry contain spindels that continuously change speed to prevent shatter. I think this is done by means of a programmable frequency controller?. But perhaps you could also do this with a timing belt transmission where you mount the timing belt pulleys eccentrically.
I'm just pointing it out because with all due respect ,you're a handy guy who can make and use something like that.
I think about how much time is lost due to shatter. There is a lot of profit and job satisfaction to be achieved if shater could be eliminated.
Drill using the carriage like a "civilized person" Shots fired! Just kidding really enjoyed the video. Doesn't suck like a dremel made me lol. No truer words have been spoken.
8:25 speed up your grooving tools, running that slow it doesn't want to cut because your running to slow for the insert. something I found to help
Great camera. Work. What sort of holder for the drill bits ? Another great video thanks from the land down under
Do you include a warning to not use wrenches on the hex flats to prevent marring in the future and ruining the finish? 😁
Horizontal
With the world
awesome video, appreciate you showing how you do things, do you use magnification to examine things? Whats your preferred way of achieving that? My eyes aren't the best, but I've compensated with lighting in the shop. I don't think I could pick up on the bur on the threads like you did without some sort of magnification. Would be curious to know if/what you use. Thanks again.
You like a humanoid CNC. I rather enjoyed this one, Stefan. Thank you.
I'm sure that PG ring guage was a freebie thrown in with your last order of drill bits and inserts 😮
Hey Stefan I just got a deckel g1l pantograph, I’m looking to convert the spindle to use er40 collets, is there any place I could get one at?
What tool holder are you using to hold your drills and reamers in the tool post? I haven't seen a decent solution for a multifix tool post
43:06 *bloop*! 😂
nice photography. Why are you working on the Emco and not the new machine or is this older footage?
This was footage from end of last year :)
Sometimes it's difficult to tell the sounds the machine makes from the sounds the machinist makes.
:-) 7:54. In spite of the problems it caused, I actually enjoyed the sounds for themselves. Almost musical.
👍👍
Does designing and producing three parts for a reactor keep the lights on in the shop? How much force does it take to gronk down on the stainless nut. Loved the sounds of the turning, bad set of brake drums, come to mind.
Well, those are not "a buck fifty" parts ;)
I surprised you not have made a flexible brush arm cutting oil applicator magnetic fixture .
Sounds to gimmicky for my taste :-) Fireballtool made something like that, he had a video on it.
I can totally understand that reaming on the lathe is a secret proces. Someting you better not share with everyone :)
👍😎
31:00 Gibt es einen bestimmten Grund, dass die Flache Seite der Zentrierspitze zum Werkzeug zeigt? Danke für das Video! Is there a specific reason that the flat side of the dead center points towards the tool?
Nein, ich glaub die hatte ich noch so ausgerichtet, weil ich letztens bei irgendwas anderem den extra Freiraum durch die Abflachung gebraucht habe.
Any album recommendations?
I am so happy I have been converted into a 'civilized person' as well, no chance of going back to the tailstock for drilling.
Do You regrind/modify Your full profile threading inserts? The thought never occurred to me despite regrinding other less expensive inserts on the D-b it grinder...
Regrind, yes - A very light dusting on the top cutting surface, to bring them back.
Super informative.
You need to update your 2023 to 2024 copyright at the end btw.
Yeah forgot to change that, since i started editing the video last year.
I was under the impression that the PG thread system was considered obsolete and is superceded by EN 50262 .
The US had the metric conv. act in 1975 and still use a obsolete system of units for legacy reasons ;)
I suspect the use of PG threads in conjunction with the bio reactors has a certain reason, that I dont know.
@@StefanGotteswinter It.would be easier to find the MH 370 plane than understand the US slavish devotion to the imperial system and fractions.
EMCO + 2023 at the end == old video? Thanks for sharing :)
Yep, iirc it was October 2023
I still have bad memories of people not cleaning 316 threads properly, then screwing in the go gauge. If the thread was tight and a tiny spec of 316 was present it would weld to the gauge. If not cautious the go gauge would then be out of spec. If you were lucky you could, under a microscope pick off the offending spec. If not, in the bin it went. Not sure, but certain thread forms and sizes seemed to be more susceptible to this issue. Have fun.
new camera?

Oh the sound of the thread releaf being cut really wasn't groovy.😉 I get the same in wood with a parting tool (occasionally).
I knew I was uncivilized, now I know why! 😂
Was under the impression you sold the Emco.
A month ago, yes.
wait .. back on the Emco? .. or just old footage? .. because you traveled back in Time?
Thats footage from october 2023 :-)
Anyone have advice for someone who would like to get started with a small mashine shop for business purposes? Does it make sense? How to acquire the first customers with no contacts in this industry? Appreciate every advice😮💨😄it seems so overwhelming
