English humour is well know to be not understandable around the world. Only a few seconds in and I laughed. Stefan and Michael Schumacker are both notable masters of it. Well done. Always enjoyable to watch and listen to Stefan.
Stefan, thaks about the brief chat about the vices. I'm still missing a good vice for my 66 years old Schaublin SV-51 milling machine. So I have done things the other way around. I have been avoiding to use my crappy excuses of milling vices and I have learned some really interesting ways to clamp the worpiece directly on the milling table. That "review" might just have pushed me over the edge to buy a small Gerardi. The hint of buying clamping hardware as separate components is really worth every word. I bough a clamping set from Flea Bay and the quality of it is really bad. For example the flange nuts had their thread off center and also tilted whichever way. It takes a lot of tilt in a nut to make it noticeable. One more time, thanks for sharing all this information in an easy-to-digest form.
Stefan, thank you again for your most timely video. Right now my mill drill, very similar to yours, is sitting in pieces as I'm installing glass scales and decided to scrape in the ways and redo the lead screw bearings. BTW, don't worry about making videos when doing projects or mods. I much prefer a narrated picture montage. I've seen many videos of mills cutting steel. A narration is as good or better because you can concentrate on the process and steps, rather than your milling tasks. I know setups for video take a lot of effort when a picture takes a few seconds. This would allow you to post more content without having to video everything.
I just bought my first milling machine here in Australia. Bare bone 45 series clone with r8 quill. What you did to yours is a bit above my paygrade at the moment but I enjoyed every minute of this video. Thank you!
As always, I totally appreciate the sacrifices you make to bring your videos to us! I know a tremendous amount of valuable time and effort goes into these very instructive vignettes. It is all much appreciated! You are a very good and captivating teacher. Your shares uplift everyone who is fortunate enough to see them. Thank you again! :)
Hi Stefan! I'm thinking it would be a good idea to put RF-45 somewhere in the the title so people who have the same mill but not with Optimum branding can find this video. Just a thought. Very interesting as always!
Hey Stefan, just wanted to say thanks. Your quill lock was just the solution I've been looking for to make tool changes easier on my mini-mill. A chunk of aluminum and an afternoon later, and I've got a simple and very effective spindle lock. (insert shameless plug for my build video here...) I appreciate the inspiration, and everything else you offer this community. Thanks again!
Thank you that was very good freaking awesome As an artist as an engineer as a Craftsman I love my work wood metal I'd love to hear another people enjoy it
You inspired me to get a similar machine and I'm gathering my confidence to do mods of my own soon. Thank you for your effort in making these video that share so much of your knowledge. Great work
Thanks Stephen. The angular contact bearing is exactly what I need for my lathe lead screw which has a similar design of roller thrust bearings. I have shimmed it up but it still has a bit of slop. All the best! Eddie
This video had so much wonderful content that pertains to my mill. I have been planning on converting the spindle to a BT30 quill for a long time. Last year I bought a Denford Triton Pro CNC Mill (VMC) that has an 8 tool auto changer that uses BT30 inserts. I wanted to change over my mill so I have the same tooling for both machines. I am also going to install a spindle clamp similar to yours. I resurfaced the bottom of my spindle head by clamping a mini bench grinder in my vice and used that to surface the bottom of the head, where the clamp mounts. I also added 2 glass scales on the z axis. One on the head, where the stop nut used to be and one on the column. My 5 axis DRO adds the two values so I always have a true Z reading. I'm going to use the 5th DRO axis for the rotary table as it can also read degrees of rotation. These mill drills are really versatile and fun to mod. Thanks for the inspiration.
Very much enjoyed this look at your mill. I only wish I could purchase as nice a machine here in the USA with all of your modifications already completed. That would be the machine I would like a lot. Thank you so much for your time and knowledge, I always learn so much from your videos, and will be waiting for your return. Take Care and Stay Safe. Bob
Hi greetings from New Zealand love your content.... Just missing your overseas brother... hope we get to see TOT again soon.... Have your heard from him....
Your level of precision & perfection is inspiring to me. I am beginning to do small updates & upgrades to my lesser equipment with this kind of video presentation as inspiration. My biggest problem is being clean and simultaneously being rust free. How do you balance clean & rust control? Can you make a video explaining how you control rust? Thanks so much.
Hey first ...thats you get when binge watching over 2 weeks . Love your exact and precize approch and machinist, and you know some quantum to👌 i read , under old tony´s video. Greets from the Netherlands Johny geerts
@@combatcurtful yes your right sir , Old tony districtacted me ..with TIG weld tips ..i need badly, but i´m joining right back in...its Tony fault realy . Lol Grtzz johny geerts
The modification I liked most ( not shown in this video) is the power Z axis feed , I copied your design for my HM46 ( RF46) and it works like a charm !
It's really astonishing how much you've improved on that mill with some hand work and other modifications. I've got an old RF-40 here still that's mostly relegated to being a drill press but you've got me wondering just how nice I could make it with a little effort. Hope you are well, sir!
I love this kind of adjustable table. setting an angle this way is really a problem in most milling when the head can’t rotate this way like a Bridgeport.
My biggest gripe with my 45 is that it lacks about 50mm of Y travel which prevents the spindle from being able to reach the very edge of the table. It's not a deal-breaker, but boy would it be nice.
i have same milling machine from 2012, it still works great. I bouth it new directly fro China, and i have ordered it with two speed 3 phase motor and quill feed in 6 ranges as extra option plus the cooling pump and tank. I got screwed for swiveling table which was also ordered but ordinary fixed table arrived instead.
Great upgrades Stefan, I only wish I knew how to scrape, something I must learn, as I have the same machine which really needs some squaring up. Interesting you noted the MT slot in the spindle, I have an MT 4 spindle with the slot, when I stripped it to fit new taper roller bearings, the central bore was full of scale and casting sand that was all dropping down into the back of the lower bearing. I had no fixed steady for my lathe therefore couldn't machine the bore, so I flap wheeled it and painted it to seal the surface. Something to look at if you ever replace the bearings. Cheers, Jon
Hi Stefan Thanks for the always intersting videos. Regarding to the Fehlmann Picomax 51: I have eactly the same opinion as you about this machine. So I have bought an older P51 one from a school for about 6k CHF. It has the CNC control cabinet and Heidenhain TNC 155 control. I also have a big Mori Seiki CNC VMC. But i must say, I mostly use the P51. It is so versatile and due to the easy CNC control, fun to work with. I can whole heartedly recommend getting a used one in good condition. You should be able to get one for under 10k CHF. Fehlmann still has all the parts etc.. Greetings from Switzerland
Some nice neat ideas and work on your mill. Mine has blown some circuitry somewhere and blowed if I can find the fault! I'm thinking expensive motor replacement but will strip it first and see if is faulty and repairable.
When i got my new milling machine same style as the mb4, The bearing were so full of chips from the factory i had to take the spindle apart and clean out the bearings before turning it on. The bearing races were scored and the company got replacements sent and the replacements were full of chips and grinding dust as well..
I heard off those problems a lot - Same for the gearbox. I can absolutely not say the same for this machine of this machine importer/reseller. As for how sloppy some things where made, there was no crap in the bearings or the gearbox oil.
Out of parallel by 70 microns is decent. My 20 year Taiwan knee mill (basically 1/3 size Bridgeport) saddle was out of parallel by about 0.6mm. I’m not exaggerating, 0.6mm. It took A LOT of work to scrap it flat, to about 10 microns.
you don't use belleville washer in the thrust bearing block, that defeats the purpose, you preload them where you do use belleville is in a split nut design on the leadscrew, you can make a zero backlash setup that way, and it also helps to cope with uneven wear of the screw, be it ball screw or acme
Fun for us, but given Stefan's high standards, it might be an epic project on the scale of Wintergatan's MMX or Project Binky. Not easy to fit around a dayjob.
Is that epoxy resin modification works for you? Have you notice any change in parallelism of Z axis to table? Im very interested in that kind of mod for my lathe. Nice glasses.

Stefan: "i've hardly done anything to it.
*proceeds to show modification/improvement to literally every critical part*
He also fitted a very swish powered quill downfeed for drilling and boring, not mentioned here!
He also didn't show the epoxy work on the column.

I am a simple man, I see a Stefan Gotteswinter video; I smash the like button.
I love shop and tool talk, especially hearing your take on it. Always stoked to watch what you share.
I feel very lucky to have come across your posts many years ago. Always nice to see another .
One of the best channels for machining on youtube, thank you for all the years of education!
Six years?! That's impossible.
When you're not acting like a baboon when handling tools they tend to last surprisingly long. ;)

Nice to be able to improve things as you go along.
Great to see the mods! Thanks for helping me dream big before I have even bought a mill! Please keep sharing Stefan.
Great ideas on how to modify the machine to be so much better. Love the dry humor. Love the exquisite detail.

thank you for uploading these videos Stefan!
I always get excited when I see one of then on my feed
Excellent presentation of all your ideas for improving your mill. Brilliant mind!
I always enjoy your videos but mostly your explanations. Your tooling setups are very well conceived along with your considerations. Thank you.
Thanks for sharing!
I ALWAYS look forward to watching your videos!

Awesome Stuff Stefan! That quill clamp is just the solution i've been dreaming of! Really like the execution on that.
You inspired me to get a similar machine and I'm gathering my confidence to do mods of my own soon.

the paths your mind follows to solve problems are scarry brilliant!! poppy
It's always helpful to see the reasoning behind thoughtful modifications and habits. Thanks for sharing!
Excellent, thank you. I can employ many of these mods on my machine. I'm sure many of us have one of these clones in our shops.
Man you are a genius... I love your work, your channel and I jus can dream with a home work shop like yours... Grettings from Colombia
Great video, nice to see the updated mods, much more precise than from factory 🙂
Thanks for the update and the great overview of your machine and its modifications.

Wow! time goes fast. feels like you just got it not too long ago
Very well done, thank you for sharing your video and expert knowledge.
Voice-over + Germany + Sunday = Church bells .
Also, I agree, there is not much worse than an uneven hand-cranking experience !
My biggest gripe with my 45 is that it lacks about 50mm of Y travel which prevents the spindle from being able to reach the very edge of the table. It's not a deal-breaker, but boy would it be nice.

Yes, Stefan, you are still good looking!
He makes more effort to get his little mill running well than many companies do for their hundred thousand dollar CNC mills.
Very interesting. But i think you forgot to tell us why you are good looking :-)
Nice video Stefan. Thanks for all the effort to make it.

I'm pretty shocked those mill screw mounts didn't have a belleville washer in there. And also, that the backlash wasn't much worse!
