nice clean work Stefan. looking forward to seeing the rest. you should make some cosine bars too, would love to see that. :)

Stefan I am so glad that your video came up on my feed list and I just had to give this one a big like when I heard you refer to common sense and personal responsibility when using tools
“Six little buggers!’ ............ priceless. Another fabulously educational video. Thank you.
Hay Stefan, I must say, I am supper impressed with your whole set up, and how clean and bright and methodical you are, I even paused the video twice to take photographs, you have given me some ideas for my shop, That was a grate Vid, Thank you, keep them coming 👍🏻

+Mark Williamson Thank you for the kind words, Mark! I love bright clean shops they dont feel as depressing as some dark dungeon ;)
I really enjoy your videos, gives me confidence to try new things myself. Thanks, and special thanks for taking the trouble to learn English!
Very nice. I almost got heart failure watching you machine-tap those 2.5 mm holes. I didn't think it could be done. I really enjoy the small scale work on this channel. And you have reminded me that a V-block is in fact a very nice 45 def setup square. Thanks.
Really like the larger holes through the length of your 1-2-3 blocks. Great for set ups.
Great job, your precision is impeccable. Thanks for the video Stefan.
You sure have achieved some fine finishing. Nice. You are a meticulous man. Great set-up for the 45 degree drilling. Another excellent video Stefan.

Hi Stefin; As always another grate video. I see you using you're copper drift in all your videos. I made one similar to that many years ago. it's a 3" piece of copper pipe with a cap on end and filled with molten lead. works grate. Keep up the good work.
Great video, great job. Thanks for sharing.
Nice cut-off process using the grinder. Great series so far!
Thank you, I really enjoyed this episode, you are one very funny guy, and laughter is good medicine! Dr. Stefan has got your prescription...Aloha, Chuck.
27:01 "The safety...guys..." German language at work. Great stuff as always Stefan. Nice work on the screws and holes especially. BTW, I saw your latest shop talk. Don't glue those tubes in. I use a similar set up in my woodshop and stuff is always getting pushed back up into the tubes. Leave them unglued so they can be dumped out.

+joshua43214 I wanted to say something very inappropriate first...and then changed my mind :) I didnt glue the pipes in due to lazyness and they will stay that way, thanks for the hint :) Fishing with a bent welding wire for short material pieces is only borderline-funny...
STEFAN Nice video As always, we pick up good practical machine-working tips which we can't read about Thanks again aRM
The magnetic lathe chuck is awesome!! Never seen anything like it..!

+dannymaciejewski They are great tools and kinda scary at the same time :)
Stefan, If I could make one small suggestion. When you chamfer the corners of a thin part with your chamfering tool. If you make a block with square faces say out of Delrin or something it will help you hold the part square and more securely. I always look forward to seeing your videos.
Very nice work Stefan you are the man!

Very cool all educational videos! Thank you!
Hi thanks for the very interesting video and very well made sine bars
No one died. That's a success.

I'm so glad nobody died.😂 Great video of making sine bars. Another project to add to my list. Thanks, John
I like lathe parting wheels. :-)
I noticed gas springs supporting your milling machine head. I presume you added them recently to cut down on the effort required to crank up the head. Do you have any details on sizing and mounting? I also liked your hand tapping method it can yield that extra bit of clearance when one runs out of z height. Keep up the great videos!
Oh, Stefan. So envy for your magnetic chuck.. Should find another pocket in my wallet for it some day ))) Thanks for sharing this, appreciate. A lot of knowledge for me
stefan nice work.
That is a nice tool post grinder. And if you are not sure about the setup, just stand off to the side so you can watch shrapnel go if it happens lol.

Hi ! Really nice work !
Hi Stefan, have you considered adding a copper face to one end of your vice's allen key wrench?
High quality instruction dude! Your going to build a center less grinder next Hugh? lol

Is it important to use a special oil for hardening parts? Will it work with oil for car engine like 5W40?
You are probably my fav precision machinist on YT... a battle with the guy just below me and Oxtoolco. Anyway, knowing the machine's (and human's of course) limits, how these hardened dudes could be geometrically perfect? Do you accept 3-5 microns (1 2 tenth for anoglophony) of error and tolerance, or any sine bars, from cheap and expensive, have a tolerance like that?
Hi Stefan, Frage? what determined the diameter of the roller. Nice multitasking, but I think the torch should have been in your right hand, but no foul, and no blisters. BTW those wiz wheels don't explode like grenades, you would have to be holding the grinder in your mouth to do damage.

+Robert Klein The diameter of the rollers doesnt matter, as long as both are the same diameter. Yeah, a lot of people are realy scared about those thin cutoff discs, but if they break, the pieces have very little mass and so dont do a lot of harm...

Hi mate. Very,very nice again. Putting you nice bars on the shaper, are you not worried that it would be less accurate than let's say grinding them, or is that coming after that?
@StefanGotteswinter

+Marcel Timmers Thank you - Yes, they will not anywhere nearly as accurate as they would if they had been ground on a surface grinder - But they are still well within 1/100mm parallelism between the bottom of the rollers and the top surface :)

well mate, you will have to follow the trend, and also buy a surface grinder. ; ) It appears to be the must have at the moment.
Very good - special request: Please leave instructions in your will for your girlfriend to the post the final video, where somebody does die. Of course, I will be very sad as we will have no more toolmaking videos - but having carefully followed how to make tools to 2 micron precision, I really want to understand the dying part as well.
Hey Stefan I'm wondering if your crossslide grinder can fit your shaper to become as surface grinder
I wish everyone in the world had common sense it would be a better place thanks

Stefan, Great work, great videos! Quick question...where do you get those 'acid brushes' you use for dabbing cutting oil. I have been looking all over, and I can't seem to find a supplier in Europe that sells them for a reasonable price. Importing them from the US, seems a bit over the top... Cheers Patrick

Hi Stefan - I'm curious how you indicated the center line of the vee when you drilled.
@StefanGotteswinter
8 жыл бұрын
+Zander Kale Just by eye, when you move the drill down into the vee you can see if it deflects to one side. If it does, correct slightly and try again until the drill stands in the centre wen touching into the vee.
Stefan, in the tool post grinding operation, did you have an independant dial indicator mounted on the traverse/compound or were you just using the lathe dials themselves to advance in?
@StefanGotteswinter
8 жыл бұрын
+Peter Thannhauser No I did it just with the cross slide dial - since I made a new dial and changed the bearings for it it runs so smooth and the movements is precise enough that I dont bother with a dial indicator :)
looks like you add some air shocks to the mill?

Hi Stefan, did you temper the rolls?
Wait... HAND TAPPING?! Where is the real channel owner and what did you do to him?
Real talent here, and at the mill I saw your really cool collet holder,,,(@@) got make one for self,, Got'a love TOT for his comment :)> HaHa!! Bear
