Stefan, I've been watching your channel for a long time, but recently I suffered a major depressive episode. I wanted you to know that your videos are helping me in my recovery. They are so calming and help to keep away the panic attacks and intrusive thoughts. Thank you again for everything that you do!
Stay in the fight brother. Everyday is a new day, and the forest is always dark and scary until you find the path to the edge. Keep searching for the path and keep your head up. You got this!
To be aware of those thoughts and recognise that they aren't helping is the best thing you can do. I'm glad you've done that. Stefan's work really is soothing to a lot of us :)
I am sad to see the Deckel tool grinder gone. I was looking forward to seeing it featured in more videos in the future. There are endless possibilities for setup for complicated tools with all those wonderful accessories.
fantastic stage by stage, simple setup that resulted in more accuracy than required was good to watch and indicated to me what can be done in a 'home' shop. thanks Stefan.
Again perfect work! I know that you avoid certain chemicals in your rooms as a precaution. Aren't you afraid of inhaling the carbide dust? Despite the extraction system, the dust still ends up in some filter that needs to be disposed of or even cleaned
Class H dust extractor, overhead air cleaner and if i feel its necessary, a ffp2 or p3r mask. Cleaning the dust extractor is a whole deal, with a mask and slow, to not throw up dust. Also having the air cleaner run while doing that.
You always present informative content! It helps visual learners to actually see the interface of the parts in the final position, but the narrative fulfills that purpose. How much do you appreciate that new lathe 😂. It sounds wonderful, and you seem to have acclimated to it almost instantly. Thanks for sharing your experience. And the editing was (as always) terrific!
Thanks again for an entertaining and informative post Stefan. I've been watching your channel for a while now, and have been surprised and impressed by your willingness to change or remove equipment to suit your changing needs. Some of the machines you have had were real beauties. I suppose if you had unlimited space you might still have the pantograph just for how wonderful a machine it was.
I have Clough42's electronic leadscrew, and it's amazing! I'm just a hobbyist, so I don't rely on it to make money, but I'll never use change gears again. It's so much easier. I know old school machinists sometimes don't trust "new fangled" technology, but if you are looking for efficiency and speed, an ELS is the way to go.
I use a lot of new fangled electronics, dont worry :-) I just prefer my lathe to be in its most important functions to be dead reliable, beyond electronics.
Wonderful attention to detail. I have to think the tool would have cut plastic OK without dressing on the diamond wheel, but doing the job correctly is a mind set that carries through all things in a very positive way. EDIT: Ah but then I remember the delrin is for test only. Very good! Thanks for bringing us along!
I am at the very early pre-stages of tool and cutter grinding. I say pre-stages, because I haven't even turned the machine on yet and I still have to figure out what I am doing. But watching your videos continues to inspire me that I will at least have some modicum of success because of what I have gleaned.
Great to follow how Stefan resolved the grinding methodologies. I wondered if Stefan had forgotten to grind a tip radius. Phew, saved by a spot of hand finishing ... marvellous.
I have been a subscriber for about 8 years now and I can truthfully say that I have enjoyed each an every video. I was wondering if you ever miss the shaper. It seemed when I first started with your channel that the shaper was the main tool in your shop. Things have changed mostly for the better. Keep the videos coming! KOKO!
7 minus a little bit and 7 plus a little bit - welcome in my world of agricultural machinist precision! The difference is the real size of that little bit.
Ahhh i am Drooling after such a bema and punch grinding fixture . Your new microscope is nice , realy your shop has so many admirable things. btw , nice that u did a new toolgrinding video for a nice sunday evening . i love those
Hi Stefan, thank you for your videos! You are doing a great job!!!👍👍👍 I have a question regarding the threadcutting on a lathe. Maybe the question does not quite fit to the topic of this video. But still... What do you think about the technique I have seen in videos of the anglo-saxon world to set the compound on an angle for threadcutting? What do you think are the benefits of this approach? In Germany it´s not very common. Greatings from Hamburg
That's a beautiful tool you've made there. Given the same challenge and what I have to work with I'd sure be inclined to try either using a warm fitting as a tap to form the threads, or to cut one into the shape of a tap.
Hello Stefan, thanks for sharing all the cool stuf that you make. You have really nice equipment. You mentioned in the video that you would like to have a 100X mag Profile Microscope. It would be cool if you make a video over the Profile Microscope how it works and the magnification. Do you have loupes and in which magnification are those? Thanks for sharing.
I was hoping to see some more tool grinding on the big S1 tool grinder. All of those different adjustments you could make, I would have loved to have seen a carbide end mill with 6 flutes being put to task.
They also work to mask off chuck pinon holes for those positions you don’t use to tighten, but compress down if you decide to use the other positions to loosen the chuck, as well as masking off tapped holes In work pieces for media blasting.
What a beautiful surface grinder. That machine has some amazing features. What model is it? If you don’t mind sharing. Thanks for the video, very informative and entertaining as always
Tool grinding video! .... How do you store those tools? In case you are able to find it in five years, when you need it again, it might become "economical" 🙂
I use a flex VCE 44 H AC shopvac which is suitable for dangerous materials, one of those ceilling mounted air cleaners like woodworkers have and if I feel that dust extraction is a problem due to weird setups, I put on a FFP2 or P3S mask.
most people go watch a movie. stefan go's into his workshop and grind a carbide turning tool. each there own as they say xD btw when the cej mikrokator 510-9 getting pulled out or would a 510-7 be good enough xD not gonna lie. acutally really want a 510-7 myself though not easy to find ( only found one on ebay for a extreme about of money )
"Tabellenbuch metall" - theres a english version too: www.europa-lehrmittel.de/Mechanical-and-Metal-Trades-Handbook/1910X-4 But I also use the engineers blackbook, also a very good reference book.
No top flat on the tool shank? I really prefer boring and threading bars with a flat. I find it makes them much easier to set up. I would make no assumptions that plexiglass will thread nearly as nicely. My experiences with it have been problematic
Very interesting video as always. I do mourn the loss of the weird and wonky grinder. As I know you like to be a little bit pedantic, you might be interested to know that Nikon is pronounced with a short I, like Nippon. Nikon is actually short for Nippon Kōgaku.
35:56 Nice microscope/computer, but call me difficult since I would prefer 55.0557° over 55°03'34" 😅. At least when I'm not talking about longitude and latitude.
Appologies for not watching through a 40 minute video, but why did you choose solid carbide to mill two small parts from plastic? Even HSS would be overkill here.
@@StefanGotteswinter If you think carbide grinds nice and quick I wonder what you consider difficult to grind. In a non-production environment I bet you've have trouble wearing out 0.3% carbon steel when all you are cutting is plastic.
Hey Stefan. Just a query about the clocking of the carbide bar. When clocking in an eccentric feature don’t you double the desired value and dial that in. E.g. for 4mm of eccentric (distance between centres of rotation) you dial in 8? As the part should move 4mm above and 4mm below the centre of rotation? It’s the way I was trained during my apprenticeship. Or by throw were you referring to the overall travel of the part? Loved the video!! Many thanks

hi Robin!
hoping that all is well with you...any new videos planned?
Keep well, sir!

Thank you Robin! Your approach to the surface grinder changed my view on it a lot!
I am sad to see the Deckel tool grinder gone. I was looking forward to seeing it featured in more videos in the future. There are endless possibilities for setup for complicated tools with all those wonderful accessories.
endless possibilities with possibly endless time investment 😅
The opening shot of this video is just gorgeous. Your photography (filming) setup between the lights and the lenses is beautiful.
fantastic stage by stage, simple setup that resulted in more accuracy than required was good to watch and indicated to me what can be done in a 'home' shop. thanks Stefan.
"home shop" might be a bit of a stretch for most people, but surface grinders are kinda acceptable:)
Always a pleasure to see a master at work!
Awesome! Enjoyed. Was glad to see the directional results on the carbide as you have indicated before. Thanks again.

when grinding the back side of the tool with the cup wheel on backwards... can you run the spindle in reverse so you are grinding towards the carbide?
Outstanding job!

Encore une démonstration de ton grand art , super boulot
Thank you, excellent!
Where do you buy the ultramicrograin solid carbide blanks? :)
Usually from pHorn.
Do you do anything else besides use a (HEPA?) shop vac (?) to deal with carbide dust such as a personal respirator, shop air filtration system, etc.?
I use a flex VCE 44 H AC shopvac which is suitable for dangerous materials, one of those ceilling mounted air cleaners like woodworkers have and if I feel that dust extraction is a problem due to weird setups, I put on a FFP2 or P3S mask.

Excelente trabalho
What about the Taper of the pipe thread? You cut a cylindrical Thread?
Theres tapered and straight pipe threads. This fitting/thread combination required a straight thread.
@@StefanGotteswinter thanks
@@chucktodd7329 FWIW, there are 2 U.S. pipe thread standards: NPT (tapered) and NPS (straight).

@@StefanGotteswinter I thought most of those in Germany had been turned into pubs a machine shop seems like a better use. :-)
Oh no, sorry to hear about your wheel guard falling off. Man that seems to be such a common issue with surface grinders...
To be fair, I only would do that with super abrasive wheels smaller than 125mm, not with regular aluminium oxide or SiC wheels.
Ich dachte immer, die Fittinge ohne O-ring hätten konische R- statt G-Gewinde. Wie wird das dann gedichtet?
Die Fittinge haben eine seperate Dichtung, die auf der Fläche dichtet.
Did you use any special material to print the gear?

Hey Stefan. What is the name / model of the indexer? Thanks.
Thats a punch grinder / spin fixture. Harig makes one, called "Grind-all", mine is a rebranded "GinTech" from Taiwan.
Hey, what's the name of the book you showed for the thread reference?
"Tabellenbuch metall" - theres a english version too:
www.europa-lehrmittel.de/Mechanical-and-Metal-Trades-Handbook/1910X-4
But I also use the engineers blackbook, also a very good reference book.
@@StefanGotteswinter I could have sworn it was the German version of the Black book of fasteners but I was wrong
Is the 30 arc-minute error due to the compound angle created by the 10deg clearance angle?
(I haven't done the maths on this)
Nope, going with the tilted spindle its not a compound angle error.
what is spindle taper on BEMA grinder-? -no reference to it on BEMA website
They use a Fisher/Precise spindle in the grinder, which have a 1:7.5 taper with a 14mm major diameter.
