I'm glad you specified you got the bearing from a box and didn't find it in the wild the same way Marco Reps harvests his wild capacitors.
As a tool and die maker, your videos always bring me joy!
Thank you Stefan, I'm far from a math guy but you broke down this issue so even I get it, great video as always.
Greetings from Florida USA.
Cheers, from Orlando.....
Secret trigonometry trick: Lay it out in a sketch in CAD 😁😂 Thank you Stefan great setup!
Much less error prone than on paper :D
@@StefanGotteswinter Yep, I do it all the time. Plus, if its fairly complex, it can be a drastic time saver.
@@CJ-ty8sv Same here. And I am not even a machinist. I mainly do woodworking.
@@doubledarefan Yep, I'll bet that probably everyone who does something with any sort of cutting / fabrication of solid materials who also has access to and knowledge of use of a CAD system has done it at least a time or two (likely more).
Very impressive setup/micro machining! Thanks for taking us along-
So much to learn, so little time. Thanks for the look.
Thanks for sharing your skills, I hope you write a machinery tips and tricks book soon. Cheers from Sweden.
Elegant as usual Stefan. I'd was hoping you'd show how you will radius the edge of those two holes. Maybe next time?
Sunday is not perfect without new SGTWR video! Pleasure to watch as always!
Hi Stefan.
Some late night viewing for me here in Sydney.
Wonderful stuff mate. Super informative.
Best regards
Robert
And from Brisbane.
I'm also in Sydney :)
Man, did I love the bar of the Mercantile Hotel back in the days👍
Yes I remember Joe Pie talking about this technique. Thanks for reminding me and thanks for the video.
Great problem solving, thanks Stefan.
its good to see you again Stefan.
Thank you for the lesson….. alway so helpful to see the concept in action. 👍👍😎👍👍
Thank you Stefan, I love seeing how machining problems are resolved!
Very enlightening!
Thank you! :)
Nice work Stefan!
ATB, Robin
Nice to see you Robin.
@@xmachine7003 Thanks.
Thank you and your customer for sharing this with us.
excellent technique.
Cheers for the tip. Also I do like the look of the fixture to hold the V block.
Another excellent tips video, always a pleasure to watch!
Great video! I hadn't thought to use a ball bearing so I could change the part angle and still touch off a constant circle!
Very clever setup and method of hole location. I learn something from you each time you put up a new video. Thank you for sharing.
Take Care and Stay Safe.
Bob
Great video production/discussion/demonstration….tks for sharing
Great tip thanks Stefan.
Wonderful work as always Stefan. Loved the technique. Also your camera work is awesome.
Very cool.. Also great video from Joe.. Seems like just yesterday I watched that.. man time flies !
thank you stefan, realy enjoy theas short tips and tricks, but also all your longer vidieos. regars richard.
A very well presented solution to a problem that is better seen than lectured about. The indexing fixture is obviously of high quality, just from the features and effortless rotation.
Nice job Stefan.
Nice technique. Thanks for posting.
I was expecting chord formulas and a calculator! Didn't think a sketch and a computer would come up. Thanks for sharing :)
Thanks Stefan...great content as always...
Very nice video. The first time I heard of you was a few years back, when John Saunders did a shop tour of your place. I subscribed to your channel a week or so ago, but this was the first of your videos I watched. You appear to be a very skilled craftsman, and with over 50 years in the trade I real that I know a craftsman when I see one. I'll be here watching from now on. Thank You for sharing.
Thanks Stefan
Always interesting, thank you
Nice, thank you Stefan.
Great work as always. Nice little tip to Share.
Another great video lesson...Thank You.
Interesting problem and an elegant solution 👍
really good. makes perfect sense too
Good video. Thanks!
Nice one Stefan!
great information Sir....Bravo
Nice video and interesting problem solving. Thanks
CAD does all pf the math for me these days as well... Looks like a pretty nice way to pick up the location! Hope all is well there. - TZ
Thanks for diagramming that technique. I want to try shellac to adhere the ball.
Beautifully filmed Stefan 8-)
I love precision milling in small dimensions, usually with a 3mm bit, interesting Rotary Chuck system. i should make this for me too.
Nice photography. Informative and fun to watch.
Thanks for sharing!
I too will be able to do this now that I have made my Gotteswinter indicator holder!
4:14 “let’s hope we don’t glue ourselves to the piece… as usual”
Great video 👍 Stefan such small holes if you had to do many would a sleeve over drill bush guide be a good alternative.
Had never thought to do that . Mostly relied on optical options in that situation.
Still learning methods after 40 years. Thank you.
nice lesson danke Stefan
Very neat, thanks.
Thank you!
Seriously. Who’s thumbs this down ?….smh.
Great video !
I have needed this method once in 20 years but it certainly is an important one when you do need. It!! 😎
Another gem. 👍🏾👍🏾
Great tip!
For tolerances greater than +/- 0.001 inch, locating ball on sharp cornered hole may be ok. Below +/- 001 you need to measure the center of the ball relative to the end of the part. Once that is established you can hold hole tolerance to gage level accuracy, +/- 0.0001inch
Some great content there . Cheers .
Very nice work, going to add this approach to my machining OS. ^_____^
👍 thanks for sharing!
TOT, Joe Pie, AVE, Abom you will be watching Cloug42 soon? Stefan & Joe and Mike Patey have my unreserved respect and admoration. Thank you.
Cloug42 is a hack
@@EitriBrokkr Clough 42 is a hack, possibly, He certainly isnt in the same league as the others but he is well on the right side of the line. He does try to work well with the resourses he has available. Yes he is a long way from the best, but at least he is trying and bettering millions of others. So I dont disrespect him.
@@EitriBrokkr I'd say he's a hobbyist, not a hack. He's also quite meticulous, there's a lot to admire in his approach even if his level of machining skill is not at the same level as the professionals on YT. And his electronic leadscrew project is really interesting, and he's at home with that because he's a software guy professionally.
@@cooperised I'm not critiquing his machining, I'm talking about his electronics and specifically that lead screw project. The guy is clueless, and carries on with this persona as if he's the authority on the subject. You can buy, for at least a decade already, all the stuff to do that. Proven and commercially available, way faster, easier and cheaper than what he "invented"
@@EitriBrokkr I don't believe he's ever claimed to have invented it. It's far from unique, and for sure there are some really well priced commercial devices around (I like the look of the Rocketronics one myself). I've no idea what he charges tbh, but plenty of hobbyists seem to like the challenge of a kit. As for the electronic engineering, well, it seems fairly sound to me - and I'm an electronic engineer. 🤷 Anyway, if you don't like a channel, don't watch, I guess...
Brilliant
Stafan, as always you show very high end work! and you dont post enough to keep me happy!! who cut the taper on the tube? poppy's workshop says HI
the technique ball bearing is pure machinig old school
The music at the beginning immediately gave me AvE vibes
Morning, Stefan!
Hi Vince
@@union310 Greetings.
Good morning!
Thanks Stefan, neat technique. Rule 0: Do not be on fire. Rule 1: Do not glue yourself to the part.
nice trick . wouldnt need that if u had a 5axis but old school is fun too
VMS make very high quality super glues including black... And a very good debonder
Very nicely done. Never have thought of that.
How is the town where you live Stephan? Did it suffer flooding?
Parallel and a roll pin if you need to do a flat surface :3
Triangle circle club 4 lyfe.
Can tell how smooth that quill is, jealous.
How would you inspect these parts so you know the hole is right? Thanks
How did you setup your depth stop for multiple parts
Do you clean up the inside of that hollow feature after this drilling action?
The break out of the drilling action.
With a drill in a pin vise, coming in from the back.
its good solution but the precission of the drilling hole depend on how precise is the bore how precise is the ball and its sitting on glue its not always that precise how you want to, Anyway for this operation its obviously useful , but productivity setting time and others , its better to use turning angle table . or 5 axis machine, Anyway point of this video is you can make everything in your scale . And i enjoyed the video . Nice work Sfefan as always. Greetings from Czech Republic. :-)
I guess he should have just ordered up a 5 axis machine for this job then...
I have used this method before as well. One thing to note and it may not have been relevant for the part you were making but how much error would you have had to build in for the edge break/chamfer you had on the I.D of the part.
Stefan, I was with you indicating the ball bearing until you spun the indexer to Check the run-out of the spindexer set up. Indicating opposite the indexer put the test indicator at 45 degrees off the equator which yields a different value than if you positioned the test indicator in front of or behind your work piece which would place the indicator at O degrees from the equator. The resultant TIR of the 2 positions is not the same.
Thumbs up!
@ Stefan Gotteswinter
Hi Stefan please can I ask a favour? Could you tell me what head clearance you need in your workshop for your milling machine at uppermost head setting?
Many thanks!
Wayne
How did you deburr that hole (since a countersink would obviously throw off the position just like a burr would)? Or is the remaining burr small enough to be within the positioning tolerance?
Good didactic video
Skill is when you can explain what you're doing .. how and why :D
Sehr lehrreiches Video. Wie verrundest du die Kante am Bohrungseintritt, im CAD sieht man dort einen Radius?
Wird mit Polierpaste auf einem Holzdorn, im Handschleifer gespannt, verknödelt (Fachbegriff :-) )
I get my sk40 measuringmicroscope and determine the zero point. But maybe the part has rounded edges...then it gets hard to do....
Did you end up modifying the mill, I thought the mb4 top speed was around 1800rpm ?
Edit: I was wrong, mb4 goes up to 3200rpm.
Great tip re. edge finding and measuring, thanks
And how many times did you actually glued the indicator point to the ball?
Just wondering...
So, zero chamfer on the central hole . i.e. dead sharp ?
How would you deburr the inside of the oblique holes?
Just with a drill in a pinvise, coming in from the back, removing the little burr.
Did you break the edges of the holes?
I keep expecting to see some blurry pictures from your electron microscope as you machine graphene and carbon nanotubes into tiny parts.
Your work is unreal, and always amazing!
This kid is fucking awesome! Excuse my language everyone, if I hurt your feelings I’m sorry. I just have to give credit where credit is due……🤷♂️
Oh man. I'd never have guessed you were a screen poker.
5.705 is the theoretical dimension - did you take into accont that the bore has a chamfered edge?
Yes, I took the actual wall of the bore as a reference, not the chamfer/fillet.
This feels like a comment the customer would make, lol.
@@StefanGotteswinter I think what G. Leuprecht meant was that your mystery part seemed to have a chamfer in the bore edge, thus the ball would be resting against the chamfer face and not at the theoretical end face of the bore, thus giving a tiny error in the position.
Ancient Trigonometry Secret: Blank piece if paper, sharp pencil, trig tables, your mind as calculator. Imagine....
Its a basic skill to be able to do trig on paper - But if I dont have to, I will use cad for speed and foolproofness.
@@StefanGotteswinter Yes, i fully agree. It just takes that well grounded experience in problem definition that you only get from Trig Class to be able to utilize cad to its fullest potentential.
If you cant describe the problem, you cannot fix the problem.
And that is so widelt evident in the thousands of youtube videos I've seen on 'how to CAD or 3DP."
I thought you would use a magnetic ballbearing?
Because , the discrepancy is still an issue my guess ...
Oh , and did i mention i hate super glue , my fingers dictate me to say that lol.
