Hi Tony , well said !☆☆☆☆☆ I love your video's also very alot. And you incorperating Stefan , into your video´s is geniusly funny !! But also showing alot of respect for him ♡☆.. Is very nice to see . Greets from the Netherlands Johny geerts
I really enjoy your long form videos too Robin. I have a harder time organizing the IG stuff but all of it is so much appreciated. You and Stefan are kindred spirits. Thanks for sharing your knowledge I use it every day in the machine shop.
Really interesting and entertaining! 👍 I work with epoxy and can give you a couple of tips; 1. Always *decant* the epoxy; mix for half the time in container 1, then pour/scrape into clean container 2 for the second half of fhe mixing time. This guarantees no unmixed components get into the final result. 2. Buy some 10ml and 20ml nurse syringes from the pharmacist. The type that dont have rubber plunger but are entirely plastic. The larger syringes have large nozzles and can suck up and inject epoxy and is a good way to get the moglice into a hole without air. 3. Never trust mold release! Rub it into the sliding parts multiple times, the rubbing/ burnishing is as important as the layer of release agent. Also, you should have rotated the main shaft once the epoxy set into a solid, but long before it reached full hardness. It becomes a solid long before its adhesive properties become full strength, so you loosen it once solid but before it is totally stuck! 😁
I have watched the video of Robin making this modification (multiple times). I enjoyed this and did not feel it was redundant because you both give different perspectives. It is also nice to watch skilled people solve problems. Thanks for sharing!
It's refreshing to hear such an expert giving credit to someone they admire so much! Both of you hold the high ground in your fields! I would love to see you both work on a joint project one day.
"It is still good to do as good a job as we can" That little statement shows your nationality even more than your accent does. Loved watching over your shoulder, thanks!
58:40 "Hehe!" Machinist joy coming out in its purest, unfiltered form. It's always a treat to see the amazing care and precision you put into your work. Thank you!
Mostly here to give the algo a bump, These are my favorite Stefan vids. Problem/solution and, making tools so much better than they were. You sir may be second to Robin but, I think it is a very close second. Truth be known, you are my favorite high precision tool maker. Thank you for taking the time to educate us.
Finally someone who isn’t scared to tap a hole with a handheld drill motor. I’ve done it many times with no problems. RUclips had me believing this process always had to be fixtured and used with a tap follower.
Und wenn der Dbit Grinder fertig ist, ist sein Wert ungefähr 30000 Euro, abhängig von dem Stundetarif 😋 Schönes Projekt in Präzision! Danke für das lange Video!
I can not say I have watched all of your video's, and I have watched many. I play blacksmith on the weekends and still always amazed at what and how you do your craft. Keep doing you! And thank you.
Stefan…. Watching you work is an inspiration. Thank you for putting in the humungous amount of work to make these very detailed, and VERY entertaining vids. You and Robin are like ‘book ends’ to the body of ‘precision’. Thank you, Robert Sydney, Australia.
I very much enjoyed this video. Mr. Renzetti may have all the credit but you did a beautiful job of filming the process. That in itself is a lot of effort. Beautiful work, as always. Thank you.
So well engineered and thought through. It's always tough to go down to my own shop and fight my humongous tolerances, you are a very good role model. Thanks for sharing man. Cheers from Sweden.
1.22 excessive play? I really like your videos and your demand of high accuracy (must be a german thing) i sometimes work as a mecanic with a german supervisor when rebuilding metal manufacturing machines (GROB, Burkhart+Weber Liebherr etc) and i really admire their strive for precision. The biggest problem was to find the right tecnical terms in a language in english so it was a wierd miscung of english swedish and german. But it worked out good anyway
Awesome.. A while back I was wondering if you would make more mods to your d-bit grinder.. Thanks for sharing with us Stefan! Take care, hope you have a great week..
Absoluter Genuss deine langen Videos, ich freue mich jedesmal wenn ein solches von Dir gepostet wird. Ich kenne diese Tage nur zu gut, wenn jede Schraube erst kurz von den Fingerspitzen berührt werden darf, sich dann aber sofort anders entscheidet und definitiv den Weg zum Boden findet. Egal was man versucht! Ois Guade nach Oberbayern aus Sydney!
Wow; just wow! That stupendous video was over an hour long but it flew by in what seemed like a few minutes. Love the thought process for the lead screw and sleeved shaft and it’s fixing method to the extended shaft. Then it got better. Brilliant 🤩
I don't think I'm ready to modify my new D bit grinder, must learn how to use it first. However, I really appreciate the rationale and detail you and Robin (and you, too, Tony!) provide. I'll be back! BTW, That epoxy bearing stuff looks interesting. I think it's an 100% solids epoxy pulled towards rigidity and toughness with a graphite filler; the modern Babbitt. I mixed a lot of epoxy in a prior life as a boat builder. When adding the hardener try to get proportions exact, if anything slight the hardener, too much hardener tends to yield a weaker, and stickier (i.e. will lift some mold releases, causing issues) result, especially with small volumes. This is the way I mixed it using a nice sized, squared tip stirring stick: 25 full stirs clockwise insure that the corners are involved with a couple of swings along the bottom edge 25 full stirs counterclockwise Again the bottom edge, clockwise 25 full stirs clockwise If you need to add fillers, do it now, and stir 25 to 50 more, depending on the filler. Keep batch size down if possible, too big a batch left too long will smoke and may catch fire. Ask me about Olaf... If kept cool and dry epoxy has pretty long shelf life. I thought I heard you mention a syringe, a good idea if the tip is large enough to easily pass a viscous fluid. Great to see you using gloves, which you might have dipped in the epoxy and smeared in the bearing hole... Don't count on the release agent being perfect, two coats burnished is usually enough, though. Tape off everything you can, despite the mold release.
Since watching Robin's video about his D bit grinder upgrade and watching how much you use yours, I finally purchased one but have not done any mods to it yet. After watching this fine video I know why I have been waiting to upgrade my grinder. f I do all of the upgrades at once I won't suffer from upgrade envy. Thanks for adding more items to my queued workload of shop upgrade projects. I can't die before I finish my list so essentially I am immortal.
It's looking great Stefan, hoping for a part 2 to see the final push. 👍👍 That Moglice is really cool, I had no idea stuff like that existed. I always learn something new from your videos, so thank you!
Beautiful work Stefan. Love the details and reasoning process. Also love the thought process which is simplify wherever possible so form follows function.
Excellent as always. That Moglice has an amazing finish. Love when you take a tool and modify it Stefan, you take what seems at first to be some major, overwhelming modifications, and break it down into simple steps and most of us could perform, albeit at a much higher standard ;) love the work as always, thank you for showing us all!
When you pulled out the skewer for the Loctite 648, I really felt that haha. Also I had never heard of the Moglice slideway epoxy before, I was quite surprised at how smooth the bearing surface came out. Cheers and thanks Stefan!
So enjoyable to watch you work as you narrate your thought processes. Very educational and at times highly entertaining too. Fabulous project, looking forward to seeing it progress to completion. 👏👏👍😀
Thank you very much indeed for documenting the how and the why. I will take this as necessary improvements to the imported clone I might be able to afford some time in the future.
I have had excellent success with 3D printing laps. Very handy to just quickly print one, and makes it easy to keep laps clean as you move to finer and finer grits. It’s also easy to control flex and add slurry channels.
51:12 The technical term for this is the martensite start temperature, in case you want to sound fancy in the future. Nice demonstration of decarburisation when austenitising in an uncontrolled atmosphere.
You, Sir, just made me buy a second D-bit grinder. One to use while the second one gets Renzetti-Gotteswinter'ed :) PS, I sent you a message on Facebook a while back about something, just checking you saw it...
After actualy seeying the video . I like to point out , that the one bearing that was not filled completly. Probably was an airpocket. As most moldings also need a bleed channel , to push the air out. Preferably at the 12 o clock position . Greetings from the Netherlands Johny geerts
Beautiful, way better than the factory original (naturally, it's you.) I'm sort of surprised that you continue with this machine given all the rest of the sophisticated equipment you have acquired.
Offsets are a great tool, 321 blocks or just a few cm , its knowing how to use them. just made a radius tool for m300, , to make ends on boxwood tools for beating lead sheet. tools for tools. . love the work.
Thanks for your video, I learnt a lot again.👍👍 But I am interested your purpose why you started to restore this grinder, because you have a Deckel S1, and a surface grinder. With these two grinder you can grind everything. Is it easyer to use, or faster the set up on the D bit grinder? Thanks!
OK, now I am ashamed of my minor tear down and cleaning of a Alexander 2CGD. I worked 23 years doing CNC R&D for orthopedics and I am impressed with your work, well done. I got this grinder just for something to putz with at home all well knowing I didn't have the tooling to do it right so all I did was clean it up a bit. I dont even have a use for it. It was hardly even used as all axis are still tight. Would you have any interest in this unit or can you point me in a direction of a buyer?
Bei ca. 50:20 konnte ich mir das Grinsen nicht verkneifen, wie der x-y-z Controller (?) an seinen Anschlußdrähten von der Maschine baumelt, umringt von Hochpräzisionsarbeit. I Love it ! 🙊🙈 Danke für all die spannenden Videos !
:D Das ist ein Yuri-Touch DRO, das ich zum testen da dran hängen hab, sieht unmöglich aus, aber bis ich sicher bin, dass ichs mag, lass ichs einfach so an den Strippen Hängen :D
@@StefanGotteswinter Oh, voll cool.. Ist sogar ein DIY Controller ! .. auf Thingyverse gibts verschiedene Gehäuse dafür zum selberdrucken, ich könnt mir aber auch ein stücl Delron auf der CNC vorstellen .. der controller der sich sein eigenes Gehäuse fräst ;)
You mention there is 30 microns of play on the left end and less on the right end. Wondering how you made sure the shaft was concentric as you cast the bearing surface. With that play on each side, couldn’t it end up at an angle relative to the axis of grinding? Thanks for your videos and sharing your knowledge and experience!
Great to see a video. Does the swivel part that you show near the end of the video have some sort of seal to keep out grinding dust because when you took it apart it sure looked like a lot came out?
Another kit project that is found in need of a finicky machinist to solve the inherent problems. You are having too much fun doing this, and you know that it will last forever, so the paint must be as close to perfection as the enginerding and machining. Now the major question is….grey? Green? Red was already used so that would be too easy. White would be perfect! Any debris immediately observed! Can we have a Group Vote? Great video as expected, the only way you operate.
I have an old Induma milling machine. The Y screw and handle are way off to the side of the Center line of the saddle. That creates a lot of stress on the brass nut and screw. It wore out the nut and screw almost to the point you could pull the screw out. I replaced the lead screw but couldn’t get brass/bronze stock big enough to remake the nut at the time (thanks Covid). So I mogliced the nut to the new lead screw to form new threads. My take-away from the experience, injecting the moglice with a syringe was SUUUUPER difficult. Went through a number of syringes. Maybe too much hardener? Too small of syringe, who knows. But there’s a pile of moglice still on my shop floor where I spilled most of it… but, the job worked. The Y axis on that mill turns fine. I just need to do a better job scraping the dovetails because the Y screw still jacks the table back and forth….
nice work Stefan!
(except for 29:00, let's hope it still runs when you're done)
looking forward to part 2!

1. Always *decant* the epoxy; mix for half the time in container 1, then pour/scrape into clean container 2 for the second half of fhe mixing time. This guarantees no unmixed components get into the final result.

Thanks for your video, I learnt a lot again.👍👍 But I am interested your purpose why you started to restore this grinder, because you have a Deckel S1, and a surface grinder. With these two grinder you can grind everything. Is it easyer to use, or faster the set up on the D bit grinder?
Thanks!
Yes - The reason is quickness of setups. The DBit grinder is the fastest of the machines for quick lathe-formtools.

best shoes for light duty shop work. I have regular steel toed shoes if i do heavy work or machine moving.
