Toolgrinding: Solid carbide threading tool

[@febobartoli]

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!

[@daveb3910]

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!

[@raindeergames6104]

Praying for You brother. I suffered major depression and panic disorder for many many years.

[@lukerickert5203]

I suggest relaxing videos are best combined with exercise away from the screen and carefully optimized meds :)

[@StefanGotteswinter]

I am glad if they help out a bit :)

[@Tezza120]

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 :)

[@ROBRENZ]

Nicely done Stefan! I agree completely about the versatility of the surface grinder. ATB Robin

hi Robin! hoping that all is well with you...any new videos planned? Keep well, sir! The 🇨🇦 🐻‍❄️ in 🇩🇪

Thank you Robin! Your approach to the surface grinder changed my view on it a lot!

[@first_namelast_name4923]

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.

[@ChriFux]

endless possibilities with possibly endless time investment 😅

[@rootvalue]

The opening shot of this video is just gorgeous. Your photography (filming) setup between the lights and the lenses is beautiful.

[@russell_gant]

Always a pleasure to see a master at work!

[@MyLilMule]

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.

[@googleuser859]

More fabulous content, thank you Stefan.

[@StuartsShed]

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!

[@tomeyssen9674]

Awesome! Enjoyed. Was glad to see the directional results on the carbide as you have indicated before. Thanks again.

[@zukjeff]

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.

[@StefanGotteswinter]

"home shop" might be a bit of a stretch for most people, but surface grinders are kinda acceptable:)

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.

[@StefanGotteswinter]

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.

[@crichtonbruce4329]

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.

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.

Hello Stefan, I enjoy your tool grinding demonstrations. This one is super! 👍

[@wrstew1272]

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!

[@jamesreed6121]

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!

Great precision grinding,Stefan.Thank you.

[@volkeresper9519]

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

[@StefanGotteswinter]

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.

[@volkeresper9519]

Ah, I see, you need a safety vacuum cleaner for that - at a corresponding price... Do you have a recommendation?

[@TrPrecisionMachining]

[@kevinkohler2750]

The earplug trick is so clever!

Ear plugs! Brilliant! Imagine would work on large hex screw heads in applications where they collect chips on mills & lathes as well. Love it

[@matter9]

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.

[@jimsvideos7201]

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.

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

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?

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.?

[@StefanGotteswinter]

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.

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.

Carbide grinds nice and quick, keeps an excellent edge and I have it at hand.

[@rockets4kids]

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

[@StefanGotteswinter]

I think I got my words wrong here :D I dialed in 4mm total throw (2mm above, 2mm below) to get my 2mm wide relief.
