00:02:52 Mistake on my side, its of course only 1,2 microns. (0,0012mm) Things like that happen to slip trough during editing, when listening to the same lines 5 times.
You also say thirty-six instead of sixty-three, but we don't mind Stefan ;) Great video. I watched it till the end, no skipping, but don't need help as I watched at 3x speed ;)
Perhaps folks don't realize we would learn nothing from buying all the solutions to our problems. Learning to solve problems is the basis for developing skills. If it weren't for skilled folks sharing their time making videos, we'd be learning only to the expand the bounds of our current skillsets. I learn so much from videos like this. Thanks for sharing your skill and experience with us.
Yep! The fact that I did so many tool builds and rebuilds early on was a huge skill builder for me - I still to this whenever possible, but sometimes I will just buy myself out of a problem (surfacegrinder) :D I am fully aware that most hobbyists have not that huge of a budget to spend on their shop, so I try to show / talk about different ways of doing something too.
Agreed completely. I sometimes wonder about the folks watching these vids if they don't understand the idea of making something simply for the exercise of learning something new.
Do you guys realise you're discussing one of the biggest issues in Western Society right now? What you are talking about is skills training. As in learning from people more skilled. I'm an engineer and started watching guys like Stefan and Robin Renzetti because I have a couple of pet projects and I need to re-learn and improve by basic maker skills. During COVID I have also been trying to learn about economics and why we all seem trapped in various economic models. If you have ever heard the management line "What's your business case for that" to any proposal then like me you already know part of the problem. I've mainly listened to a Scottish professor named Mark Blyth. He studies how economics and politics interact with the rest of society. About 2 weeks ago he interviewed a sociologist who's trying to explain why EDUCATION and other things like infrastructure and health care are struggling across America. I'm Australian and we have the same issues. What she worked out was starting back in the 1950s economists started creeping their way into EVERYTHING and by the 90s had become the loudest voice in the room for almost everything including EDUCATION and with it *SKILLS TRAINING.* It was an Ah-Ha moment for me she explained why these people do this "What's your business case for that?" It explains why countries like Australia, America, Britain, etc. have shortages of skilled tradesman because to train them was met with "What's your business case for that?" I encounter graduate engineers with no practical skills because our universities are also dominated by "What's your business case for that?" Don't get me wrong sound economics are important, but something like mining companies (where I work) need to be able to dig dirt, crush rock and sell ore. They can't make money if they can't sell ore. They can't do that if the machines break down because the engineers were ignored, maintenance wasn't done and there's nobody to fix things because there wasn't a "business case" for that. In Australia (like a few other places) we need to build a whole new generation of power stations because there wasn't a "business case" to replace them. That combined with our complete failure to keep training people means we have a shortage of people to build them. *We have an even greater shortage of people who can train them.* Sorry for the rant, but people like Stefan, Robin Renzetti, Tom Lipton, Joe Pieczynski and others who not only have great skills but can also TEACH them to others are so insanely important right now. I know most of the people in this community know how great these guys are for sharing their skills. But there is a much bigger problem and their ability to TEACH is going to be damn important.
Well, I loved every minute of that, especially the ultrasonic stuff, as theres lots of heresay about what to use in them, and how, but if you've had yours for 10 years and not killed it, I think I can trust how you use yours, especially with the quality of your work Stefan. The collet and collet nut tip is great!! Love the new surface grinder what a lovely machine. I don't think any of your viewers would ever think you would boast. You do super fine, precision work, you need machines you can trust, and you've never bought one to flex on other people that I've seen. I look forward to seeing all the cool stuff you make with it. Now, as for me, Im off to get psychiatric help after sitting through this whole video! Thanks for all the tips over the years Stefan and hope 2022 is really good to you and the business!
Hallo Stefan, ich möchte dir einfach mal DANKE sagen!! Durch Deine Videos habe ich sehr viel gelernt! Ich arbeite Beruflich zwar mit Holz (Geigenbau), allerdings bin ich von der Feinmechanik begeistert und baue mir verschiedene Spezialwerkzeuge selber (Habe einen Drebank, eine Aciera F3 Fräsmaschine, eine Deckel G1L, eine Kuhlmann S0 Stichelschleifmaschine und eine Aciera T10 Ständerbohrmaschine). Deine Videos sind immer sehr gut erklährt. Grüsse aus der Schweiz
Thank you for sharing your knowledge and tricks with the world. You can choose to educate, or entertain yourself. I will choose the education with entertainment every time. Take Care and Stay Safe. Bob
Thank you Stefan, I am seeking help as you recommended, but the help , unfortunately, is as rare as you are. Your attention to even the subtlest details combined with your humor makes for an enjoyable experience.
And about your final comment, who in their right mind would skip the end of the video? You are far too humble (if I may take the honors of calling you my friend even though we have not met in person). You provide incredible amounts of information and education for free in a profit driven world. I am constantly amazed by the wealth of experience that you pass along to those of us who didn’t have your skills and opportunities. You are the kind of person that I respect and would be honored to be associated with. Great stuff you are doing, please accept my thanks for doing so.
I was literally just about to tap some m4 threads in 316 stainless when that tip dropped Stefan. Unbelievable timing and I think you just changed the way I tap holes on my machines. Fantastic content as always 👍
Skip over 90% ? Are you mad? Your stuff is always pure gold! I'm not skipping over a single second! I am happy for you that you got the new grinder! It looks like a wonderful machine. Very precise and very well built! Thanks for doing these videos! Very much appreciated! :)
Hey Stefan, another great alkaline cleaner for ultrasonics is "Alconox Powdered Precision Cleaner". It's a very pure detergent; I use it for cleaning both aluminum parts and optics. When I work on optics, I often rinse with deionized water instead of ispropyl alcohol.
I like the long videos. Don't worry about limiting them to a half hour because your viewers enjoy the long format. You have a calm collected demeanor that's enjoyable to listen to.
With deep respect I say, sick minds stick together, and I would prefer to see your your videos or at lease 95% of each video. Thanks for the work you put into them.
I watch all your videos all the way through. Once you are sufficiently crazy they don't even treat you any more. To preserve a small fragment of sanity I watch nearly all videos at 1.5 or 1.75 times speed. to save time. You get used to the speed after a while although some folks naturally talk fast so I have to run those a little slower. Of course your feed rates and material removal rates are impressive. When I try to achieve the same performance on my machines I can't. I tried to order 1.75X cutters and they don't know what I am talking about. I've tried to get 1.75X employees too. No luck. When I meet youtubers in person that I listen to a 1.75X they seem very laid back and relaxed. .
I’m so pleased to have come up with the same solution for tiny hole spotting. I made the same tool from a broken PCB drill using a setup kind of like you’d use to cut facets in a gemstone. I needed to drill some 0.002" / 0.05mm holes in PEEK tubing and I needed to spot them first. Thanks for the video. I really appreciate your skills.
An hour very well spent Stefan. Though in fairness, most of it was staring at the Star Trek calendar. I will have to watch the video again and concentrate this time.
the year posted at the end of the video is 2021. it's 2022 now. I am shocked at such a glaring error from someone with such a repuation for accuracy. :) seriously your work is always a pleasure to watch. you are a very fine craftsman. I don't do machining anymore but I once did so I like to watch these!
To see how far you have come is incredible. I still remember you trying to hand scrap something. I remember you started on the shaper and then after about 100 passes later you called it good. To the work you do now
I guess I need to seek help, lol. Sure, I can buy pretty much any tool I need, but I learn so much more by making it, and it's so much more gratifying when I use it. And I've never taken any of your machine videos as you bragging.
Out of all the Chanels I watch yours give me the most inspiration to create the tools and equipment I want. And I do watch 100% of your vids so you might be rite I do need help thanx man keep em comeing !
Excellent and informative video, I really appreciate the knowledge and experience you share. I’ve known about ultrasonic cleaners, but didn’t understand how and why they work. Now I have one on order for a carburetor and log splitter project I have. The tapping tips are excellent and I could have used your techniques many many times. Thanks so much.
Wow awesome grinder! 👍👍 (At the cost of a sports car... 🤔) Here is a suggestion for the ultrasonic cleaner; in the supermarket you can buy bright coloured silicone webbed mats, about 120mm square and 2mm thick. They sell them with the kitchen goods as a "grip aid" to help remove jar tops. The silicons is stable and heatproof, and you can use them in the ultrasonic cleaner to stop your glass jar or large items from rubbing on the stainless container. 🙂
I respect you for having time to make videos for us, considering you have your full time job and your home business too. Thats dedication. I thankyou, and im sure everybody else does too. 👏🏻
I typically tap small threads with a Jacobs 8.5N chuck clamped on the tap, the shank of the drill chuck in a drill bushing. "The ER collet has an eccentric boss that we DONT machine away" Oh god the nightmares that brought bad. Bema grinderrrrrr What an awesome machine. The aesthetics are so delicious.
That certainly looks like a high quality machine. I'm just a hobbyist and I have not seen one of those manual grinders before. Looking forward to seeing more videos of it in action.
Lol! You said "you really need help if you made it this far in the video"... That's why I'm here! I garner so much information and ideas from all your videos! What a treat! Great tour of the new grinder! I know you'll reap many benefits from this purchase, however expensive it was! Thanks for your time and sharing! 👍😎✌️
Love the shop talks.....another way to guide a very small tap is by machining a holder for the shank of the tap, the tap shank slides into a precise hole (essentiall a tube) and allows the tap shank to be guided up and down as the tap threads in and out.....the top of the small holder is solid and can be tightened into the chuck or collet and held tight.....quick easy and simple to make, combine that with your knurled tightener and its a win win combination and can be used for multiple taps of the same shaft diameters.....Keep up the fantastic work..... Don
Congratulations on acquiring a new tool for your precision work. Don’t feel like you need to explain the purchase of a lifetime tool to use in your work, anyone who watches your videos will know that your Teutonic Logic Circuit will have long before determined that it was as Spock would sat “ logical “. You have spent considerable time being in the position to do so, good for both you and your viewers. Your enthusiasm is evident, it looks like a better than Christmas Gift and you can use it to insure your future. Thanks for sharing!
Here in the US we have a warehouse club thats owned by Walmart called "Sams Club" they sell a Degreaser concentrate for $6/gallon that is very similar to "Purple Power", it makes 32 gallons of cleaner if you mix it by the label, or if you mix it 1:1 it will strip paint- I use it in the Ultra-sonic on everything except Aluminum Carb bodies as it turns them DARK (For those I use Berrymans) My old, worn out 1946 Brown and Sharpe No2 worn out 6x18 Surface Grinder weighs 1,400 lbs.......
Congratulations on the new addition to the shop. Very well deserved and looks like it was built just for the master machinist that you are. I watched every second of this episode (like I do with all episodes). All the best to you…… 👍👍😊👍👍
Stefan, the load is also torsional, in use trying to twist as much or more so, as “ vertical “ load. So you don’t get to take 3mm cuts with a 10mm bar. SO! You did good. Loved the project. More similar stuff for us who don’t question your training!
I see You turning those hand wheels, leaving a note that Your hands are pretty worn out after a day of grinding - and I start to think about my own two worn-out wrists, having Carpal tunnel syndrome surgery on both in 2021. There has to be a way of motorizing those hand wheels? I see some joysticks in the future...😁 Anyway! Congrats on that beautiful grinder! I'm looking forward to seeing it in production use in future videos. Not only the grinding itself, but also the setup and meteorolgy behind it. You always have the most interesting ways of doing things like this. And I'm learning tons of good stuff. from You! Thanks for sharing! Erling from sunny Oslo, Norway! 😎🖕
I can think of no one more deserving to have such a nice grinder, and to squeeze every little bit of precision from it than Stefan Gotteswinter. I hope it serves you well.👌🏻💯
Congrats on that new machine. Business is looking up and I’m happy for you it is. What will you be able to do now that you couldn’t before? Bigger parts, clearly. More accuracy? Looking forward to seeing those jobs. So, no doubt, are your customers.
Great Job!! Just yesterday I was tapping using a small handle, the tap kept on slipping, what a brilliant solution and so simple!! Thank You BTW I was making your boring bars from a couple of years ago
Another wonderful video! The time flies by, and then it's over too soon. I really want to see this grinder in action, with some interesting problem to solve, that it will handle. Very well I'm sure.
Nice grinder . Certainly a different but useful configuration . Both of my grinding machines are German as well , the WMW ID grinder & the Jung surface grinder that i have just bought . 👍
"If you made it this far..." You might not be fully considering what details your viewers pick up, even when watching a shop talk video. There's a lot of learning done just understanding how any why certain decisions are made. Things you take for granted, are sometimes very meaningful to the rest of us.
Ultrasonics are the best. I can’t say how awesome they are with the right cleaner. I have a large one and barely ever have to scrub anything anymore. Parts come out 100% clean. Using the jar is great for nasty parts.
Excellent content as always so thank You! One detergent that is alcalic and which is easily available is the dish washer detergent. Those are designed to remove fat and not to harm cutlery. However, alcalic solution will usually attack aluminium. That is especially true when the detergent contains lye (sodium hydroxide). Actually having aluminium shavings in a lye solution produces hydrogen. This is because lye and water react with aluminium creating sodium aluminate and the hydrogen will just bubble out. That reaction can be quite violent and the hydrogen gas is ... well ... it is what it is. Edit: I need to seek help 😊
I precision grind my horizontal band saws this way also before silver brazing them together in a custom jig for alignment when I make up my new blades, it greatly increases blade joint strength, by increasing weld surface area, most blades are just butt welded together that increases the chance of breakage at the joint!
It's always an interesting hour long video on a grey dreary day. It's not always how much the machine cost, but how much enjoyment Stefan gets out of using it in his little factory. I'm sure he's got visions of future projects already, just have to wait for the warranty to expire. I'm impressed that he's got his own root cellar, so , he better get going in the garden soon.
Seems Austrian's have a better sense of humor than Germans! 😂 I'm pretty sure I need therapy as I watched the full hour and forty three seconds, you do have a calming effect though Using drill chuck for guide plus putting a flat on tap was an addition to Joe Pie's mini-tap wrenches I modify old Honda carbs( from mid 1970's) The damage ultrasonic cleaners can do from cavitation is very dramatic on zinc based parts. Way too many motorcycle shops seem to think it's the 'best' way top clean carburettors, it's not but it is a quick way to destroy them. It's fast but generally a very bad idea. I've had an ultra sonic cleaner for ? years but very rarely used it, glad you showed some different uses for it,
We use straight water in our ultrasonic bath and the turbine bleed filters are placed in a plastic bag with a small amount of the LPS Precision clean. Almost no wastage.
00:02:52 Mistake on my side, its of course only 1,2 microns. (0,0012mm)
Things like that happen to slip trough during editing, when listening to the same lines 5 times.
In other words, it's a 3% or 4% difference.
Nowhere near 20%!
Yup only 3.6% no biggy
Nice as always, thanks for all Stefan!! Waiting for the Next video
You also say thirty-six instead of sixty-three, but we don't mind Stefan ;) Great video. I watched it till the end, no skipping, but don't need help as I watched at 3x speed ;)
Question, besides the deflection, how much does it effect the chatter? Because that is the real enemy… I also prefer the grind ones, for quick setup
Perhaps folks don't realize we would learn nothing from buying all the solutions to our problems. Learning to solve problems is the basis for developing skills. If it weren't for skilled folks sharing their time making videos, we'd be learning only to the expand the bounds of our current skillsets. I learn so much from videos like this. Thanks for sharing your skill and experience with us.
Yep! The fact that I did so many tool builds and rebuilds early on was a huge skill builder for me - I still to this whenever possible, but sometimes I will just buy myself out of a problem (surfacegrinder) :D
I am fully aware that most hobbyists have not that huge of a budget to spend on their shop, so I try to show / talk about different ways of doing something too.
Agreed completely. I sometimes wonder about the folks watching these vids if they don't understand the idea of making something simply for the exercise of learning something new.
Hear! Hear!
Do you guys realise you're discussing one of the biggest issues in Western Society right now?
What you are talking about is skills training. As in learning from people more skilled.
I'm an engineer and started watching guys like Stefan and Robin Renzetti because I have a couple of pet projects and I need to re-learn and improve by basic maker skills. During COVID I have also been trying to learn about economics and why we all seem trapped in various economic models. If you have ever heard the management line "What's your business case for that" to any proposal then like me you already know part of the problem.
I've mainly listened to a Scottish professor named Mark Blyth. He studies how economics and politics interact with the rest of society. About 2 weeks ago he interviewed a sociologist who's trying to explain why EDUCATION and other things like infrastructure and health care are struggling across America. I'm Australian and we have the same issues. What she worked out was starting back in the 1950s economists started creeping their way into EVERYTHING and by the 90s had become the loudest voice in the room for almost everything including EDUCATION and with it *SKILLS TRAINING.*
It was an Ah-Ha moment for me she explained why these people do this "What's your business case for that?"
It explains why countries like Australia, America, Britain, etc. have shortages of skilled tradesman because to train them was met with "What's your business case for that?" I encounter graduate engineers with no practical skills because our universities are also dominated by "What's your business case for that?"
Don't get me wrong sound economics are important, but something like mining companies (where I work) need to be able to dig dirt, crush rock and sell ore. They can't make money if they can't sell ore. They can't do that if the machines break down because the engineers were ignored, maintenance wasn't done and there's nobody to fix things because there wasn't a "business case" for that.
In Australia (like a few other places) we need to build a whole new generation of power stations because there wasn't a "business case" to replace them. That combined with our complete failure to keep training people means we have a shortage of people to build them. *We have an even greater shortage of people who can train them.*
Sorry for the rant, but people like Stefan, Robin Renzetti, Tom Lipton, Joe Pieczynski and others who not only have great skills but can also TEACH them to others are so insanely important right now. I know most of the people in this community know how great these guys are for sharing their skills. But there is a much bigger problem and their ability to TEACH is going to be damn important.
@@tonywilson4713 Hear Hear. I agree completely.
Thanks for the tips Stefan. I always prefer breaking my taps by hand rather than in a machine so this will be useful information.
😅

"If you made it this far - you need help". Stefan, my man, you are the help i've been needing all this time.
Hallo Stefan,
ich möchte dir einfach mal DANKE sagen!!
Durch Deine Videos habe ich sehr viel gelernt! Ich arbeite Beruflich zwar mit Holz (Geigenbau), allerdings bin ich von der Feinmechanik begeistert und baue mir verschiedene Spezialwerkzeuge selber (Habe einen Drebank, eine Aciera F3 Fräsmaschine, eine Deckel G1L, eine Kuhlmann S0 Stichelschleifmaschine und eine Aciera T10 Ständerbohrmaschine). Deine Videos sind immer sehr gut erklährt.

Right after a couple of minutes into the video i know that the hour i will spent is well worth it!
Awesome, really looking forward to see some "reasonable good quality" work on the BEMA :)
Thank you for sharing your knowledge and tricks with the world. You can choose to educate, or entertain yourself. I will choose the education with entertainment every time.
Take Care and Stay Safe.

You know a machine is of exceptional quality when Stefan doesn't try to modify it at all.
Won't stay that way for more than a year...
The bubble on the tap handle is a genius idea.
I like the long videos. Don't worry about limiting them to a half hour because your viewers enjoy the long format. You have a calm collected demeanor that's enjoyable to listen to.

I love your idea for using the machine for aligning the taps. Very simple, but very effective, thanks
Thanks for sharing your expertise, thought processes, and subtle but very funny sense of humor.
Thanks for taking the time to share, Stefan. That grinder is a really nice machine. Congratulations on the acquisition.
Cheers,
Reuben
Excellent comment on negativity is not productive. Life is so much better with a positive attitude. 👍
Always something more to learn... Thanks Stefan for taking the time to share with us out in "TV land"!
Nice chat, thanks Stefan. Nice TNG calendar.
An hour very well spent Stefan. Though in fairness, most of it was staring at the Star Trek calendar. I will have to watch the video again and concentrate this time.
Good stuff and watched it all. The advise on using the ultrasonic cleaner is priceless. 👍
As usual : Clever and very interresting !! THANK YOU STEFAN !!

Wow awesome grinder! 👍👍 (At the cost of a sports car... 🤔)
Here is a suggestion for the ultrasonic cleaner; in the supermarket you can buy bright coloured silicone webbed mats, about 120mm square and 2mm thick. They sell them with the kitchen goods as a "grip aid" to help remove jar tops. The silicons is stable and heatproof, and you can use them in the ultrasonic cleaner to stop your glass jar or large items from rubbing on the stainless container. 🙂
A sports car will be worn, rusted away and obsolete in 10 years, the grinder will last :-)
The silicone mat is a great idea, i will give that a try!
I respect you for having time to make videos for us, considering you have your full time job and your home business too. Thats dedication. I thankyou, and im sure everybody else does too. 👏🏻
Stefan, totally enjoyed the video, especially with the new grinder, a very precise piece of equipment for the shop, regards from Auckland NZ.
I typically tap small threads with a Jacobs 8.5N chuck clamped on the tap, the shank of the drill chuck in a drill bushing.
"The ER collet has an eccentric boss that we DONT machine away" Oh god the nightmares that brought bad.
Bema grinderrrrrr What an awesome machine. The aesthetics are so delicious.
That certainly looks like a high quality machine. I'm just a hobbyist and I have not seen one of those manual grinders before. Looking forward to seeing more videos of it in action.
Oh! Excellent! Thank you, Stefan!
very good video stefan..thanks for your time
Brilliant Stefan, I laughed out loud when you said "and aluminum magnets are quite rare"
Lol! You said "you really need help if you made it this far in the video"... That's why I'm here! I garner so much information and ideas from all your videos! What a treat! Great tour of the new grinder! I know you'll reap many benefits from this purchase, however expensive it was! Thanks for your time and sharing! 👍😎✌️
thank you stefan! your videos are always fascinating and inspiring
Hi Stefan,
Perfect as usual :-)
Thanks a lot.
I´ve tested the small center (starter) drill by manufacturing a small sampel. It works great!!!
Congratulations for your new grinder... Beautiful piece of mechanical equipment... ❤, and as always very usefull tips...
Congratulations! That is a very cool machine. Your hard work and skills allowed that to happen, and you should be very proud of it.
Congrats on the new grinder Stefan! I'm excited to see it used in some upcoming projects. 👍👍
Thank you for making the videos. I appreciate all the tips that I have gained watching them. The new grinder looks lovely.
Thanks Stefan, your work inspires and I love the grinder layout, very nice machine.
Love the shop talks.....another way to guide a very small tap is by machining a holder for the shank of the tap, the tap shank slides into a precise hole (essentiall a tube) and allows the tap shank to be guided up and down as the tap threads in and out.....the top of the small holder is solid and can be tightened into the chuck or collet and held tight.....quick easy and simple to make, combine that with your knurled tightener and its a win win combination and can be used for multiple taps of the same shaft diameters.....Keep up the fantastic work.....
Don
Congratulations. Nothing wrong with being proud of your work and your journey. Fantastic.
I thoroughly enjoyed this video Stefan. Your surface grinder is a Brilliant piece of machinery.
26:44 For those watching in low res who can't see the numbers, he says 36.4 deg but means 63.4 deg. Thanks for the awesome content as always! 🙂
I was just confused about that as I tried to recreate the angle myself. I later realised he meant 63.4 ty for also pointing it out👍🏻
Congratulations on acquiring a new tool for your precision work. Don’t feel like you need to explain the purchase of a lifetime tool to use in your work, anyone who watches your videos will know that your Teutonic Logic Circuit will have long before determined that it was as Spock would sat “ logical “.

Here in the US we have a warehouse club thats owned by Walmart called "Sams Club" they sell a Degreaser concentrate for $6/gallon that is very similar to "Purple Power", it makes 32 gallons of cleaner if you mix it by the label, or if you mix it 1:1 it will strip paint- I use it in the Ultra-sonic on everything except Aluminum Carb bodies as it turns them DARK (For those I use Berrymans)
My old, worn out 1946 Brown and Sharpe No2 worn out 6x18 Surface Grinder weighs 1,400 lbs.......
Congratulations on the new addition to the shop. Very well deserved and looks like it was built just for the master machinist that you are. I watched every second of this episode (like I do with all episodes). All the best to you…… 👍👍😊👍👍
Very neat grinder! Congratulations on the purchase!
Congrats on the new grinder Stefan and I look 2x the hole video 😉👍🎂
That was an excellent video. More entertaining than the last three things I watched on Netflix. I'm jealous of the BEMA FSM 260!
Stefan, the load is also torsional, in use trying to twist as much or more so, as “ vertical “ load. So you don’t get to take 3mm cuts with a 10mm bar. SO! You did good. Loved the project. More similar stuff for us who don’t question your training!
I see You turning those hand wheels, leaving a note that Your hands are pretty worn out after a day of grinding - and I start to think about my own two worn-out wrists, having Carpal tunnel syndrome surgery on both in 2021. There has to be a way of motorizing those hand wheels? I see some joysticks in the future...😁
Anyway! Congrats on that beautiful grinder! I'm looking forward to seeing it in production use in future videos. Not only the grinding itself, but also the setup and meteorolgy behind it. You always have the most interesting ways of doing things like this. And I'm learning tons of good stuff. from You! Thanks for sharing! Erling from sunny Oslo, Norway! 😎🖕
I can think of no one more deserving to have such a nice grinder, and to squeeze every little bit of precision from it than Stefan Gotteswinter. I hope it serves you well.👌🏻💯
Congrats on that new machine. Business is looking up and I’m happy for you it is. What will you be able to do now that you couldn’t before? Bigger parts, clearly. More accuracy? Looking forward to seeing those jobs. So, no doubt, are your customers.
Great Job!! Just yesterday I was tapping using a small handle, the tap kept on slipping, what a brilliant solution and so simple!! Thank You BTW I was making your boring bars from a couple of years ago
Another wonderful video! The time flies by, and then it's over too soon. I really want to see this grinder in action, with some interesting problem to solve, that it will handle. Very well I'm sure.
Nice grinder . Certainly a different but useful configuration . Both of my grinding machines are German as well , the WMW ID grinder & the Jung surface grinder that i have just bought . 👍
"If you made it this far..."
You might not be fully considering what details your viewers pick up, even when watching a shop talk video. There's a lot of learning done just understanding how any why certain decisions are made. Things you take for granted, are sometimes very meaningful to the rest of us.
Ultrasonics are the best. I can’t say how awesome they are with the right cleaner.
I have a large one and barely ever have to scrub anything anymore. Parts come out 100% clean.
Using the jar is great for nasty parts.
Another great video from Stefan. Wow what a nice grinder! Thanks for sharing and take care!
Wow! What a great looking machine the Bema is. Congratulations on getting it and thanks for showing it in such detail.
Congratulations on both the new machine and the achievements and success that have made it possible for you to acquire such a lovely grinder!
I must need help enjoyed the video all the way through, very nice your new grinder
Excellent content as always so thank You!
One detergent that is alcalic and which is easily available is the dish washer detergent. Those are designed to remove fat and not to harm cutlery.
However, alcalic solution will usually attack aluminium. That is especially true when the detergent contains lye (sodium hydroxide). Actually having aluminium shavings in a lye solution produces hydrogen. This is because lye and water react with aluminium creating sodium aluminate and the hydrogen will just bubble out. That reaction can be quite violent and the hydrogen gas is ... well ... it is what it is.
Edit: I need to seek help 😊
Congrats Stefan on the grinder. It could be a hobby machine in a few decades, as a restoration project 😂
I precision grind my horizontal band saws this way also before silver brazing them together in a custom jig for alignment when I make up my new blades, it greatly increases blade joint strength, by increasing weld surface area, most blades are just butt welded together that increases the chance of breakage at the joint!
Enjoyed…great discussion/demonstration….awesome grinder
This vid was a bit of a grind. But well worth it. Cheers and congratulations on the new machine.
thanks for teaching, I learn something new from each of your videos.
Another good and informative video. Well organized and presented. Thank you. OK, OK, I will seek help.
I AM seeking help.. I am watching you...
Great little machine. You have every right to be proud.
Russ
Nice Surface Grinder....! You will be glad you have it.... Enjoy your videos!!!
It's always an interesting hour long video on a grey dreary day. It's not always how much the machine cost, but how much enjoyment Stefan gets out of using it in his little factory. I'm sure he's got visions of future projects already, just have to wait for the warranty to expire. I'm impressed that he's got his own root cellar, so , he better get going in the garden soon.
Seems Austrian's have a better sense of humor than Germans! 😂
I'm pretty sure I need therapy as I watched the full hour and forty three seconds, you do have a calming effect though
Using drill chuck for guide plus putting a flat on tap was an addition to Joe Pie's mini-tap wrenches
I modify old Honda carbs( from mid 1970's) The damage ultrasonic cleaners can do from cavitation is very dramatic on zinc based parts. Way too many motorcycle shops seem to think it's the 'best' way top clean carburettors, it's not but it is a quick way to destroy them. It's fast but generally a very bad idea.
I've had an ultra sonic cleaner for ? years but very rarely used it, glad you showed some different uses for it,
Love the Star Trek calender!
I really enjoyed your shop talk
Thank you stefan. Top shelf per usual. Cheers from vermont
Congratulations on the new machine. Beautiful
Congratulations for your new grinder. I'm looking forward to seeing it with googly eyes!
OH! the Eyes! I forgot to put some on.
Excellent video as always Stefan
Great addendum to the shop.
awesome addition to the shop
I made it thru the entire video. Guess I need help😂
Good content👍
That's a great grinder! Lots of ideas flowing for me after watching that--thanks!
We use straight water in our ultrasonic bath and the turbine bleed filters are placed in a plastic bag with a small amount of the LPS Precision clean. Almost no wastage.
Perfect timing I'd just sat down for a cup of tea!
