That lathe dog (about the 12:30 mark) for turning between centers is a brilliant idea with the brass drive plugs. Another exceptional video, saw something new on 3rd watch.
Prachtig gemaakt. zeker de tool die je gemaakt heb om tussen de centers te draaien !!!!!! Ook de handpers is mooi ;-) Kijk uit naar de volgende video ..
I have now received a great offer from a friendly UA-camr. 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.
There is a lot of demand for working drawings of this mini grinding machine. But I don't like spending many hours behind a CAD program to make decent working drawings. However, if there is anyone who enjoys doing that and would like to volunteer for it, that would be great! I have photos of every part, and almost all the important measurements are included. That could be a sufficient source for a set of useful working drawings. If that works, I will make an extra video with some detailed explanations about the materials and construction and of course you will also get all the credit you deserve in that video.
Hello Michel, I follow your account a long time and I love what you do here. I am a engineer and I can and will draw your Design in CAD. I use Solidworks. If you like, please contact me... I will be glad to read from you shortly Regards Thomas
@@thomaskaemmerer608 O, Wow! That's a very welcome surprise Thomas! I don't have your email address, but you can find mine on my home page of this channel (it's somewhat hidden for the spambots) Shall we discuss it further by email?
@@Michel-Uphoff Good to hear. Let me know if you want a free premium forum membership, and you can post your videos on the forum whenever you want (including any old tool videos you have). We have many YTers doing the same.
In fact, the whole lathe moves (look at the rag hanging at the right). But because the tail stock is closest to the camera, you see it moving the most. I still have to secure the lathe, which is now on rubber caps, to the workbench.
@@Michel-Uphoff Yeah, I saw that, I wasn't trying to root cause the reason. What I meant is that it looks like the tailstock is moving in relation to the spindle, like the bed is twisting. It may just be an illusion and it is moving monolithically, but getting that bed bolted down to something stiff will likely help things.
@@Bakafish Yes, it's an illusion, I would have noticed any deflection in 2,5 years working with this lathe. That said, bolting down will help image stabilization when the camera is on it's tripod. Real soon now.. 😇
When I have to mill small parts (and that is very often), the max 8 cm distance between the jaws of this small machine vise is more than enough. When I place it longitudinally, nothing sticks out of the bed, and it can be accurately aligned very quickly with two precision parallels (one snugly in a T slot, one between the vice and the one in the T slot). You can probably see that in a video of mine somewhere. Alignment takes a handful of seconds and works very accurately. So this is the preferred orientation when I know I don't need to do that across. Sometimes it is simply necessary, as in this video when sharpening flat edges on the rotor shaft. The Y-axis has only 11 cm range, which would be insufficient for this task because the 10 cm cup wheel does not clear on both sides of the workpiece.
Thomas Kaemmerer has made the most beautiful drawings👍! See part VII for more information on how to get these drawings for free.

Terrific job Michel on refining the overall unit & utilising the prototype parts, Well done!!
Looking forward to the next instalment.

Nice followup. We shared this video (alongside the previous ones) on our homemade tools forum this week 😎
Nice. There will be at least two more video's before the tool grinder is finished, probably three.

Dear Michel, did you in the end use tapered roller or angular contact bearings for the spindle? Or did you go with regular ball bearings? Thank you.
I went for two precision regular ball bearings
@@Michel-Uphoff Thank you!
It looks like the tail stock was deflecting during those between centers cuts.

I’ve never seen a vise mounted on a milling machine in the orientation that yours is, is there a purpose behind it?
When I have to mill small parts (and that is very often), the max 8 cm distance between the jaws of this small machine vise is more than enough. When I place it longitudinally, nothing sticks out of the bed, and it can be accurately aligned very quickly with two precision parallels (one snugly in a T slot, one between the vice and the one in the T slot).

that is a clever lathe dog. Is it your design?
Yes it is.
