Prototyping a tiny tool grinder

I built my current tiny diamond disk grinder more than three years ago, it always has been a useful little machine. But have some wishes. Here I build a prototype of a more versatile tiny grinder. And also do a KZbin experiment: A voice from the computer..
Hope you enjoy and please comment!

I have now received a great offer from a friendly KZbinr. He is willing to make drawings of my Tiny Toolgrinder! So, if all goes well, a video will be released soon with drawings and some detailed information about the construction.

[@DaveClark-hb4yj]

Hi Michael, where can I get the drawings for the grinder? TIA.

[@Michel-Uphoff]

​@@DaveClark-hb4yj email me, and I will send the drawings to you. See kzbin.info/www/bejne/pnXTZIGsa6egppI

Approx 36 years ago, I used to be a somewhat regular visitor in your garage. You introduced me to the wonderfull world of computers (I still tell the tale about you giving me my first 20mb hdd). You inspired me to pursue a career in IT, graduated cum laude, and have now been a software engineer for over 2 decades. Thanks a lot for this!

When I think back to those saturdays, I can still smeel the cigars :)

A voice from a distant past! I don't remember who you are, but I do know that you just put a huge smile on my face. Meharis... (stinkstokken)

[@frkThsP]

My name is Coen, my mother used to babysit your daughter L. in Houten. You gave me a 'portable' computer (25kg, EGA crt, suitecase sized, I still regret throwingvit away) At the time you build/repaired pendulum clocks and played Commander Keen on your DIY joystick, because you broke all the others out of frustration.

[@Michel-Uphoff]

Hey Coen! Now I remember. That back braking luggable computer, I think it ran on diesel. I'm glad to hear that you're doing well! And now I'm still building stuff as you can see.

[@topduk]

I'm 80% done a very similar build, and it's funny this pops up and gives me some confirmation about my design ideas being somewhat sane.

[@bambukouk]

liked it very much 👍 although I don't usually like machine voice , it worked well her Thank you

[@Watcheyes]

A small lapping machine, something like this one and I'll buy immediately :D well done!

[@colincreedtattoomachines]

Another very interesting build & video Michel, Well done!!

[@Engineerd3d]

Awesome project!. Thank you for sharing.

[@brucematthews6417]

Great project ! ! ! I'm wondering about adding an option for a travel stop on the sliding block and some manner of four sided holder for grinding the ends of end mills. I've got quite a few that are chipped on the corners and worn up around 1/8 inch of the side flute edges. If I could rough hand grind them back then true up the nose edges on something like this I'd be able to use the end mills a time or two before they were just simply too short.

[@Michel-Uphoff]

I am pondering the possibilities of an extension to sharpen drill bits (which you could see as a two flute end mill). That end stop is a piece of cake. Maybe I will come up with something useful in the near future.

[@ronmurphy9819]

I loved your video. It was refreshing with the wonderful music. Very nicely done. Thank you. I’m looking forward to your next.

nice build!

[@HM-Projects]

Excellent job as usual Michel. I don't mind the plain text or spoken one, either is fine.

[@timmienorrie]

The spoken text worked well but I don't mind on screen text as the viewer can pause, read the text and continue. Great machining. Thank you.

[@MrMojolinux]

Put on a small flex LED light and Bob's yer uncle!

[@jakubkopec9313]

Light is the sign of grinder quality.

[@wizrom3046]

I dont like the fake computer voice. But your project and video are very good! 👍

[@termlimit]

I like the spoken text. Makes a world of difference. Did you work from plans, cad drawings?

[@Michel-Uphoff]

It is not my working method to spend days in CAD or at the drawing table to fully devise an instrument. This was a prototype, and as I said in the video, I had no clear-cut idea of how to build this device. I had some basic ideas and made simple working sketches of the more precision demanding or complex parts (I think you can see some of them in the video). While building I made some changes because it looked or worked better.

[@jeremylastname873]

I’m just glad that you shared this with us. I’m an Appalachian mountain boy who lives in Texas, USA. You can bet that my “English “ isn’t. 😂

[@jonedmonds1681]

Spoken works well as it is difficult to watch detail and read subtitles😊

[@taranson3057]

Now all you need is a floating air spindle and a way to guide end mills to sharpen the flutes and the end of the end mills

[@Michel-Uphoff]

End mill sharpening is a whole different game. Let's see first if I can make an accurate working drill sharpening attachment on the final model. If that turns out to be a succes, who knows..

[@taranson3057]

Thank you! As you can read here, not everyone appreciates it. But classical music is my second love, so I will persist in accompanying my video's with music. There a more than enough videos without music to enjoy for those who don't like it. 🙂

[@oldhick9047]

@@Michel-Uphoff I am very much a music lover but not a connoisseur. The background "music" on many KZbin videos are best listened to with the sound muted.

[@JasonRosinger]

Hi Michel, great design! I think I'm going to make one :) Also, I think your voice is plenty comprehensible. The computer voice can be a little unnerving and I think I speak for a lot of people when I say that your voice is just fine how it is.

[@lohikarhu734]

It's fine to use robot speech, but, in a way, there is more of 'you' in a video with you speaking... I'm from a country (whose soldiers played an important part in the Netherlands in 1944/1945, my father included) where very many people are not native-english speakers, but we manage to understand. There are people from other countries who struggle a bit with english, but I think, speaking for some viewers, we appreciate your efforts, in BOTH the work, and your commentary, and no one is laughing at you... clear!!??

[@alainblanc5738]

I mean : a genius...

[@kidkv]

You should not be climb cutting on a manual mill, it only takes the cutter digging in once to mess up a part or blow up the cutter

[@Michel-Uphoff]

Depends on the mill. Mine has almost no backlash and is climb cutting in aluminium and free cutting steel without any problems as you can see.

[@zachaliles]

Judging by the work he's doing with it I think he knows his machines better than you do.

[@oldhick9047]

It depends entirely on the machine and just how well one knows their equipment

[@kidkv]

@@Michel-Uphoff I had no backlash in my mill, till the one day I did a climb cut and found out the nut backed off and gave .015 backlash and broke a HSS cutter, what I was milling was no longer in the vise

[@kidkv]

@@zachaliles you can know how your machines work all of the time but it will only take one time.

[@bobwilson7684]

fantastic, just a bit more balanced edition/timing with the music

[@Michel-Uphoff]

Yes, I noticed. Fade-in and fade-out and no voice and music at the same time would be so much nicer. I made a mess of it in the last minutes.

[@mftmachining]

Excellent work, but the music is extremely annoying. Machining sound is good enough.

[@Michel-Uphoff]

The music was too loud (at the end) and I forgot a decent fade-in fade-out. Will correct that next movie. I'm sorry, but there will be music in my future videos .

Nice 👍 Also, I accidentally clicked downvote, then re-upvoted it - was aiming for the share button 😅

[@7alfatech860]

Love the saw/lathe option! BTW, I much prefer your voice to the computer's voice; that voice sounds stilted and like it is trying too hard sound posh and it emphasises everything a bit too much. But please do whatever is easiest for you rather than for us: making videos is hard work, and you make excellent content👍

[@Michel-Uphoff]

You haven't heard me speak English yet. Trust me, that's worse than this computer voice. How bad is it then? Well, it's very bad. It's like an unadulterated Dutchman trying to speak English. That bad 😱.

[@pcharliep61]

Hello from Kurunjang in Victoria Australia, I just came across your channel and really enjoyed watching this video on the build. I noticed you also have videos on some modifications to make it into a tool and cutter grinder something i have been wanting to build for a long time. Looking forward to seeing those video next. Cheers

[@jimsvideos7201]

I don't think there's a wrong way to produce the narration for a video. Writing your own captions is best for automatic translation to other languages but this text-to-speech is precise enough that the automated speech-to-text (and then translation) should be accurate also. The grinder is a neat project, and I enjoyed the music too.

[@alainblanc5738]

The question must have been already asked : How do you compare your Proxxon lathe and mill vs chinese counterparts (which are sometimes more powerfull machines (up to 1kW) ?

[@Michel-Uphoff]

This is a question that is very difficult to answer concretely. It all depends on how much you want to spend for a lathe. In China everything is manufactured, from cheap rubbish to high-end machines. Don't believe the stories you read that everything from China is rubbish. It's a matter of price. In general, you can say that machines with the same precision, quality and options are cheaper to buy in China because of the lower labor costs. But sometimes the shipping costs are so high that it is not worth the effort. And you will have to read very carefully about all aspects of the machine, and the company. I don't know which country you live in, but be aware of any import duties. In any case, be warned if it sounds too good to be true. If you're someone who does enjoy making a poorly finished, lousy-adjusted, lathe completely tip-top, then you could take a gamble with one of those dirt cheap ones.

[@nerddub]

I've been using an 8x16 850W mini lathe i got for about $600 for almost 5 years. I love it and it suits my needs fine for now, but I did ALOT of work to get it there. Replaced spindle bearings, fixed tailstock alignment, added a cam lock to my cross-slide, QC toolpost, COMPLETE disassembly and clean / fit everything back together to get good results with it, along with countless other upgrades, the proxxon machines just seem better built IMO and I've easily spent the proxxon in upgrades. But I do enjoy the slightly larger work envelope and I love a good side project, so YMMV

[@mastermaker666]

Stop the experiment!!!!(a robot sounding voice is Ok to listen to, a genuinely natural voice is OK to listen to, anything in between however is right smack-dab in the middle of uncanny-valley where you are constantly reminded of the real sounding voice you are hearing not being real, listening to it makes most people uncomfortable in some way) Explanatory text is way better and the vid is too good to be let down by many feeling a need to watch it on mute. Great design on the T&C grinder though, holder for a collet-block and that would also work for sharpening endmills and the same goes for sharpening drills, and lots of router-bits...)
