Hi Stefan i build over the last half a year my DIY Mini Surface Grinder step by step and was very satisfied as I saw that you have this video online .Now that I'm close to ready I just needed such a good video teaching me how to make the Wheel arbors cause I didn't want to design my own 😎🤠 thank you for your good work and good explaining ☺️👍 P.S. I made the chuck backstop the time you put the video about it online and they are worth their weight in gold specially when you have more than one part to work with 🤓👍
I've been retired for over 10 years and miss the shop, I did have a similar project and made a special adapter where the adapter tapered on both sides and a bushing that fit the front end with same taper , once tightened with spindle nut it held on. noticed you use a diamond wheel on the cutter grinder to sharpen hi speed tool, bad idea you'll ruin the diamond wheelBorazon is for steel, diamond for carbide
I learned some very useful things in this one. How to use a scraper, and I never thought of using my tool and cutter grinder by hand like that. I'm also seriously tempted to do that chuck mod. It is really good.
Awesome timing! I have been trying to come up with a plan for arbors on my Elliot 8-20 surface grinder, you have done an excellent job here thank you JBFromOZ
I don't need to make this because I was clever enough to inherit a universal grinder (surface grinder and tool & cutter grinder in one). Also I don't have any fixtures for using it except the mag chuck, no clue how to use any if I did, and it does not have interchangeable arbors. Basically I have a surface grinder with a head and table which can be independently angled should that ever interest me. And no way to avoid re-dressing wheels every time I mount them. But I saved a lot of money! :)
Hi Stefan, Looks like nutella sandkuchen, but you need raspberries and powdered sugar, on a diet? New series Stefan in the Küchen, but he will show how to build pots and pans. Waiting for Part 2.
I'd suggest that he watch Chandler Dickenson on forging fry pans, for a new take on metal work, but he would drive himself crazy checking for run out with the dial indicator ... ;-)
Stefan, what Kyocera insert were you using? I'm picking tooling for my WWII South Bend 16" x 60" lathe with a non-stock 3hp motor and rated max spindle speed
I have an overwhelming feeling like he low-key was showing off the work stops on his Chuck which btw are time savers and eliminates having to indicate your work every single time...
So, I have to ask, is the music an homage to Simon Gruber? Every time I hear that music I imagine front loaders piling gold bars into the back of dump trucks :)
Always enjoy your content. 'One day' I'd like to hear your thoughts on the what I suspect is Chinese tool/cutter grinder. Any modifications, shortcomings, tools you made using, cutters sharpened, different setup modes... etc.
Are you sure you are making the relief deep enough? The relief should be flexible enough to allow for thermal axial expansion of the grind stone without too much pressure. My experience is limited to bench grinders and table saws, so the standard thickness on surface grinders should be correct. Probably not an issue on the aluminum bodied grindstone you showed.
Very well thought out part production set up on your lathe Stefan. So how long until you build or adapt a bed mounted turret setup from another small lathe. :-) Your idea or not it's still a clever way around the problem of having two grinders that spin in opposite directions.
That tailstock is sick! just wondering what type of T /C grinder do you have? mine and most of the one's iv used have a tapered spindle. excellent channel! !
Hi Stefan, thank you for this video. I also have a lip515 surface grinder and would like to find aditional wheel huds or adaptators. Could you produce them for me ?
Absicht der informierung. Wie wäre es wohl herausgekommen wenn man einfach 1 Phase am Kabel getauscht hätte? Dann liefen beide Maschinen in eine Richtung. Wenn das bei der Maschine ginge die in die unpassende Richtung liefe... Weiss ich ja ned aber bei mir ging das. Grüsse tolle Arbeit =)
Hi mate. I would have been very jealous of your lunch a few months ago, but now we have a German supermarket here and we can buy all those nice European goods again. How is this? Are you testing a carbide insert again? It looks like it's working quite well, though.
Always interesting Stefan, I see what appears to be components to your 5C indexer and a couple disks, are you planning on making different index plates for it?
Hope you are ok :) Thats my lathe file, it has of course a file handle, it just didnt get into frame. And yes, I am filing right handed on this machine, as its small enough to do it safe. I would not do it on a machine with a 250mm chuck :)
Novice here: are you supposed to file with the chuck spinning the other way? so that in case the file snags it pierces the wall/shield instead of your chest?
Hi Stefan, I've seen your videos and I admire you do wonderful stuff and you're very accurate, congratulations. I wanted to ask why you keep the tilt. Is it for greater precision? Or just why do you have to thread? A greeting soon. Fabio Sorry but unfortunately I have to use a translator.
I still don't quite get why you don't just pur the 'outside' jaws into the chuck and butt the parts against those instead of the back stops (or maybe I've forgotten earlier remarks about that?) ... WHAT no shaper for the key slot?
Hello Stefan, what toolmaker's microscope do you use these days? Thank you for the video, in the process of making arbors for my Astra AR5-E T&C grinder.
Stefan, I bought some used wheel adapters and found out some of them were right hand threads. I think I can machine a key similar to your solution but have a question. Did you notice any unbalance in the altered hubs?Thank you and keep up the great videos!
Stephan, Interesting tailstock .... Which you explain before the end of this sentence, ROFL, Did you make the tailstock? I see used lathes from time to time with missing tailstocks that seem to be for sale elsewhere for $4-500. There may be some interest in making an improved replacement.
BTW: Solche Unterlagscheiben gibts fertig, Z.B. bei VW. Werden dort bei den hinteren Radlagern eingesetzt. Man merkt es deutlich, Du denkst Deutsch und sprichst Englisch. Ist lustig, besonders wenn Du mal wieder ne Vokabel suchst.
Have you published any info on the lathe insert you're using? I have been looking for something for my 10x22, and it looks like you're getting good results.
I have a question on which I have found no answer...Why and when should we prefer a drill over an end mill? I've made a part which required plunging a 20mm end mill in the roughing process and the result got me wondering...Why drill?
Drills are cheaper and easier to sharpen. I've also heard that endmills don't like plunging very much. I would assume that has to do with the point angle keeps the drill where it should be, whereas the endmill is just relying on the rigidity of the tool and the machine. To put it another way, can you imagine trying to cut a hole using an endmill in a hand drill?
The cost problem is understandable bet the result made me consider it as it was almost like it got reamed without even making a pilot hole or a spot drill! Plus I always prefer to drill in the mill even thought it doesn't have a quill...
Not all end mills can plunge. Some do not cut in the very center, so if you try to plunge with them, they leave a plug in the very center and that plug will stop the downward travel once the cutting edge reaches the depth of the clearance of the center. Generally if you want to drill a hole in/thru something, a twist drill is preferred because you have a broad range of diameters to select from, they're reasonably accurate, they cost less than an end mill, can be easily sharpened, and can drill a deeper hole than a end mill of a similar diameter.
"When Jonny Comes Marching Home." It is am American Civil War song. Can't decide if eh is playing it as a quiet statement about our politics, or if he recently watched Die Hard With a Vengeance and is paying homage to Simon Gruber
Doesnt make much sense, as the machine has the sparkguard and the vacuum attachment on the left side. And also a surfacegrinder that runs opposite to every grinder around the world, thats not what I want ;)
I felt like I was watching a Pratt and Whitney video with you using all the standard measures to set your machine movements. :-)

Looks like the back stops are working out great. Really nice job on the whole video Stefan
Very nicely done Stefan, enjoyed.
ATB, Robin
Thanks Robin, appreciate it :)
Your detail is enviable. Very nice work.
I learned some very useful things in this one. How to use a scraper, and I never thought of using my tool and cutter grinder by hand like that. I'm also seriously tempted to do that chuck mod. It is really good.
I really like seeing that workstop in action, and the tail stock too.
your a great machinist, explaining everything at a simple way, thats great
Nicely done. I really like the hole dial indicator.
13:00 I use a 4-1/2" hand side grinder, with cutter in the vice to grind the bulk away. js
Great video/build/discussion/instruction......love the Chuck backstop
Awesome timing! I have been trying to come up with a plan for arbors on my Elliot 8-20 surface grinder, you have done an excellent job here thank you JBFromOZ
Great performance Stefan, well done!
Thank you!
i like the chuck stops, ingenious
German efficiency, with humour, with cake, and coffee. ;-)
I enjoy all your videos, the quality and precision of your work. Thank you. Ed K. Cleve. Oh. USA
Thanks Stefan! I need some of these, man does that stop work like a charm, well worth the effort.
Great vid , Enjoyed it .. Good job man ! Thumbs up..
Thanks for the video, Stefan.

But I saved a lot of money! :)
Thanks Stefan, I will now have to make some arbors for my LIP - I now need cake and coffee :)
Hi Stefan, Looks like nutella sandkuchen, but you need raspberries and powdered sugar, on a diet? New series Stefan in the Küchen, but he will show how to build pots and pans. Waiting for Part 2.
I'd suggest that he watch Chandler Dickenson on forging fry pans, for a new take on metal work, but he would drive himself crazy checking for run out with the dial indicator ... ;-)
They would be the most precise pots and pans ever.
Fabulous work deserves a nice tea break! 👏👏☕️🍰🍪
nice work.
Watching those facing cuts you took make it pretty obvious you have that lathe tuned up to near perfection.
Great videos. Looking forward to more. Thanks
Thanks for another great video! You share such neat tips. I always learn something new.
Love your work!
Stefan, what Kyocera insert were you using? I'm picking tooling for my WWII South Bend 16" x 60" lathe with a non-stock 3hp motor and rated max spindle speed
Nice footage, thanks for sharing Stephan :D
Gute Demonstration - klasse gemacht!
I have an overwhelming feeling like he low-key was showing off the work stops on his Chuck which btw are time savers and eliminates having to indicate your work every single time...
Gute arbeit geleistet. Vielen dank.
Danke :)
nice Video Stefan, cant wait for the next one
tchuss
good video, new to machines, I learn much from your videos
So, I have to ask, is the music an homage to Simon Gruber?
Every time I hear that music I imagine front loaders piling gold bars into the back of dump trucks :)
Always enjoy your content. 'One day' I'd like to hear your thoughts on the what I suspect is Chinese tool/cutter grinder. Any modifications, shortcomings, tools you made using, cutters sharpened, different setup modes... etc.
Backstops paid for themselves!
That intro and outro music reminds me of the movie Die hard!
Are you sure you are making the relief deep enough? The relief should be flexible enough to allow for thermal axial expansion of the grind stone without too much pressure. My experience is limited to bench grinders and table saws, so the standard thickness on surface grinders should be correct. Probably not an issue on the aluminum bodied grindstone you showed.
What are the part numbers of the Kyocera insert and tool holders are you using?
Very well thought out part production set up on your lathe Stefan. So how long until you build or adapt a bed mounted turret setup from another small lathe. :-) Your idea or not it's still a clever way around the problem of having two grinders that spin in opposite directions.
So with a 3.0mm pitch leadscrew, you can cut 3.0 & 1.5 & 1.0 & 0.5 & 0.25mm pitch threads, engaging wherever you want? That is some cool info... :)
Thumbs up for the intro music alone
Ha! Was not sure if I should use it, but I think I will stick for some time with it :)
Then work stops on the chuck are F'n genius.
Good choice of music!
That tailstock is sick! just wondering what type of T /C grinder do you have? mine and most of the one's iv used have a tapered spindle. excellent channel! !

Always interesting Stefan,
I see what appears to be components to your 5C indexer and a couple disks, are you planning on making different index plates for it?
I about had a heart attack when I saw you file right handed with what appeared to be a handleless file at about 7 minutes in.
Hope you are ok :)
Thats my lathe file, it has of course a file handle, it just didnt get into frame. And yes, I am filing right handed on this machine, as its small enough to do it safe. I would not do it on a machine with a 250mm chuck :)

WHAT no shaper for the key slot?
Hello Stefan, what toolmaker's microscope do you use these days? Thank you for the video, in the process of making arbors for my Astra AR5-E T&C grinder.
An ISOMA, A very much older Version of the M114.
Stefan, I bought some used wheel adapters and found out some of them were right hand threads. I think I can machine a key similar to your solution but have a question. Did you notice any unbalance in the altered hubs?Thank you and keep up the great videos!
Love your videos. Why did you use the end mill to drill the hole?
End mill or was it a Roto-broach?
Roto-Broach, i guess. If you stop the video, you can see a bit of the core in the broach
Sure looked like one. I don't have many yet but intend to get more as I need them. They do work remarkably well.
Love all your videos.
Is there a reason you cannot just swicth 2 fases to go counter clock on al machines?
Hey Stephan! Good video. Tell me about your toy lathe. I think this may be what I need to start.
Stephan, Interesting tailstock .... Which you explain before the end of this sentence, ROFL,
Did you make the tailstock? I see used lathes from time to time with missing tailstocks that seem to be for sale elsewhere for $4-500. There may be some interest in making an improved replacement.
I did the modification, yes:

Another good video. What size are the LIP wheels?
Eine Frage: benutzt du @3.53min Alkohol zum kühlen/schmieren? Kann es sein das du generell (bis auf Gewindeschneiden z.B.) Alkohol als KSM benutzt?
Nein - Den Spiritus (oder Isopropanol) benutze ich nur bei Alu - Für Stahl nehm ich normales KSM, Schneidöl oder am liebsten garnix :=
Welche Körnung und welchen Schleifscheibentyp benutzt du zum Schleifen des Drehstahls?
Schade das dieses Video nicht in der Muttersprache erschienen ist! Englische gibt es ja genug!
Die Gelegenheit für dich eines auf Deutsch zu machen :)
Sure do enjoy the comity in the comments section. By the way the video is great too. Thank you for sharing.
Thank you - I enjoy the comment section too, pretty much all the comments I get are reasonable and friendly :)
Watch out for the torque generated when the wheels start. This alone can loosen a nut with time.
Rough and coarse wheel on the bench grinder 😅
BTW: Solche Unterlagscheiben gibts fertig, Z.B. bei VW. Werden dort bei den hinteren Radlagern eingesetzt.
Man merkt es deutlich, Du denkst Deutsch und sprichst Englisch. Ist lustig, besonders wenn Du mal wieder ne Vokabel suchst.
Have you published any info on the lathe insert you're using? I have been looking for something for my 10x22, and it looks like you're getting good results.
It looks like a 1/2" CCMT, but maybe thinned down to fit the lathe?
Sorted it out from other videos and some google-fu. I think they're Kyocera CCMT060204HQ, also known as CCMT2152HQ.
I have a question on which I have found no answer...Why and when should we prefer a drill over an end mill? I've made a part which required plunging a 20mm end mill in the roughing process and the result got me wondering...Why drill?

What’s this about hss ruining a diamond wheel?
End mill drilling? Its ok?
Did you make those back stops? If so, do you have a video?
Here ruclips.net/video/8czgFc5Avcs/видео.html
Hi Stefan, what was the reason that you filed the threads after you cut them. thanks in advance
Deburring, I'd expect
It boggles the mind what you could do if you had a bridgeport and a bigger lathe.
You should have just changed the direction of rotation on the surface grinder! ;)
Then it would spin the same direction like ThisOldTonys surface grinder. Can't do that ;)
Or just keep the wheel fixed, and spin your shop around it.
Or make a key in the nut itself. Then there would be absolutely no possibility of it moving.
Stefan, nice breakfast you have there! :-) (19:55)
Ha. That brain fart @0:57
are they built from 1144?
SAE 1213 if I am not mistaken (9SMn28k or Iso 1.0715)
@@StefanGotteswinter Thx for your excellent video on this. I'm about to tackle this project myself. Do you think 1144 would work ok
What material are these made of?
Freecutting mild steel.
What is the intro music?
When Johnny comes marching home
"When Jonny Comes Marching Home."
It is am American Civil War song.
Can't decide if eh is playing it as a quiet statement about our politics, or if he recently watched Die Hard With a Vengeance and is paying homage to Simon Gruber
Perhaps from Dr. Strangelove?
Rewire the surface grinder....
Doesnt make much sense, as the machine has the sparkguard and the vacuum attachment on the left side. And also a surfacegrinder that runs opposite to every grinder around the world, thats not what I want ;)
your lathe is so quiet
The beauty of a belt drive - No noisy gears :)
You Can't grinding tools!
