Prototyping a tiny tool grinder 

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

​@@DaveClark-hb4yj email me, and I will send the drawings to you. See ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pDp3Nv6Bmp0.html

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)

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.

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.

Dankjewel!

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.

Light is the sign of grinder quality.

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..

@@Michel-Uphoff you can do it, I know you can 😎

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.

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. 😂

Beethoven Piano Sonata & Bach Brandenburg Concerto

@@MrMojolinux Thank you .

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. 🙂

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

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 .

@mftmachining, You clearly prefer rock music no noise is a better description lol. Nothing better than some Bach while machining !

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.

@@Michel-Uphoff you may be a bit too much of a shy kid..) you will find the tunnig for the new format, cant hesitate, great contents and direction of the show, simple smart and non agressive, so much thanks for that. brilliant hacks learning a lot, much respect sir.

Nee, want al werkende ontworpen. Wel wat schetsjes van complexere onderdelen. Als ik de definitieve versie ga maken, maak ik wel een nette werktekening.

@@Michel-Uphoff Dankjewel. Je maakt mooie dingen .Ga zo door...

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.

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

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

@@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

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

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 😱.

@@Michel-Uphoff no one can bastardize our language worse than us, and we're kinda proud of it. You couldn't possibly compete with us, haha!

LOL!🤣

I use a dust mask when grinding.

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.

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
