56:00 sometimes this can be hard to swallow. When your just trying to be helpful and show a better way. The Engineer may not have time to explain, or "sell" you on why they want things done in such a way.
Learning from own mistakes is part of improvement, learning from others mistakes is saving money and why I'm watching those youtube videos:) Great job anyway! Thx.
In the FP1 arrival thumbnail it almost looks like you're making the mill fly out of the delivery truck! When you can do that it means you've reached Stefan levels of mechanical art mastery. Your videos are always worth buckets of brass chips, thanks for sharing and take care!!
So surprised noone took the "using gauge blocks as clamp support" bait - was almost expecting to see the comments explode on that :) Great video, as usual. Thank you!
Stefan, your videos are great. Superb engineering skills are so relaxing to follow. Your patience is way better than mine despite my double the years of angers. Your English is excellent and sometimes I laugh. Eg: when you "dial-indicatererd" the part off camera. Very proud to watch your tenacity.
Very much enjoyed this video. As always, it's like going to school watching you machine parts like these. Looking forward to your next video and that Deckle FP1 in action.
I don’t usually do this, but I waited until Monday morning so I could read more comments that way. Sometimes when I watch these videos when they first come out there aren’t many comments yet.
Stefan, much more interesting than watching the funeral of the Queen, and that one part is just the cookie cutter I'm looking for the holidays. I'm surprised you went full bore on the brass part and didn't make a test part of some less costly material.
Admitting to your own mistakes is something an experienced person does. With that said, those parts look absolutely dead sexy. Wonderful work as always.
Interesting. Lathe work with a blow torch. Need to remember that. Also I wonder whether you had concerns about removing the brass cylinder from the mandrel after drilling the holes? I would have thought the little drill burrs would cause removal issues at the interface of the mandrel.
The deep groove cylinderical part on the mill would have been super cool done in the lathe with the tool post router spindle and and carriage engaged. Like a horizontal ramp path. If the lathe can run at that low of a feed/rpm.
Melting down te chips from all the parts and casting the 6th part would have been fun to watch 😎 Seriously though its a lot of scrap that could be melted into something usable. Nice looking parts in the end.
Thank You, found this video very interesting! Those engineers that do not wish to discuss a project with an experienced machinist, that is a sure sign of inexperience on the part of that engineer. You should of course use all knowledge available for best results. Agree on the "complicated" parts making money, it is impossible to compete with cheap mass production as a small business.
I have been running through a lot of your back catalogue and way hey a new one comes up. Enjoying your old stufff by the way even though i have seen them all before. Now time for me to give you a hint. Rathervthan using abs/inc for each groove you can give each one its own coordinate as a "zero" call thr first zero 1, the second zero 2 etc. Think in terms of tool offsets on the lathe. The zero function doesn't interfere with your Abs setting but be warned the abs will alter all the zeros you have set.
Stefan, when I order material for complicated parts I always order at least material for one extra. Larger series even a few. Otherwise I learned you have send a postcard to Mr Murphy to join the party. If you order extra you often don't use them in my experience which is nice to have in storage for a future job or recurring order. Thank you Stefan!
Had a pile of aluminum chips I was pulling out by hand and there was one razor sharp ribbon of stainless mixed in. The stainless snagged and made a cut that went halfway around my finger. So yes, I now only use pliers or a chip hook to clean out the lathe.
Yanking on stringy aluminum chips is THE WORST because it's not really sharp, so they'll rip your flesh rather than cutting and those kind of wounds take much longer to heal. I still manage to get myself every few years with that trick.
22:07 why not extending tool path to half of the tooth on the right? That way, you can do two tooths in one pass (half of the left tooth, full in the middle, and half of the right).
Klasse Arbeit, Stefan. Der Fog-Buster ist insoweit aber ganz gut, als er dir hilft, das re-cutting zu minimieren. Wäre vielleicht auch bei der 1mm Ball-mill ganz hilfreich gewesen. Hat auch ohne geklappt, klar, aber bei so kleinen Werkzeugen geht mir immer der Puls hoch. Liebe Grüsse aus Frankfurt👍
Fascinating video. very complex parts... How do you evaluate how much money to charge the customer? Did a customer say "ok, that's too expensive, we will make it on our own?" Obviously if it's a simple job like turning a simple design that's fine - but how to you calculate (in general, not actual numbers) the price? Would it be like: Xhours of running the CNC+Expected broken/dulled CNC/lathe/endmill bits/tools +electricity bill+material cost+hour wage = final price? I love turning brass (on my tiny lathe/mill brass and aluminum are preferred materials) but I fully agree - it's bloody expensive.
Well, I have an hourly rate that I use to quote a part. I look at the part, guesstimate how long it will take me to machine it, make fixtures, do the cad/cam work and how expensive the material and tooling I need to order is. Add all that up, add 25% and theres your price :-)
Yes, absolutely - I collected all chips from this project seperate and sold them as scrap. I do that with brass/bronze/aluminium, larger shops will also do it with steel and stainless.
There is another channel here from right around the corner where I live (Clickspring ,Cairns, FNQ) who does melt down brass water armatures into molds and then uses them for making parts on his lathe. No idea if those would be to material spec then though..
Another interesting video. Thanks. What make of Multi Fix tool post/posts are you using? Do you have the original ones or others? I’m planning on purchasing one from PW TOOLS.
Is adjusting the run-out of a six-jaw chuck better than centering the workpiece in an independent 4-jaw chuck? A six jaw self-centering chuck is very expensive compared with a 4-jaw.
56:45 Designers that says such a thing are working in super secret companies that are working with very secret things or are an uneduceted assholes. Knowing your workshop is fundamental in beeing a good designer. Manufacturing is as part of a machine as design is. Great video btw.
@@StefanGotteswinter that is what I talking about. As I understand, some designer said that thing to You. And I think that he is wrong to not to talk to machinist.
You sound a lot like a professor I know. He is Dr. Chadoba. I work with him a little at the University of Texas at Arlington. The way you speak is very close to Dr. Chadobas speech. I recognize the German speach.
Could you use an end mill, in a grinder fixture, on the lathe, as a possible solution to the issue you mentioned? I guess that might require a fairly low spindle rpm? Wouldn't your motor controller allow that? I don't recall you describing the motor setup on your large? (My bad wenn I habe dass vermisst) M f G'n
I made some wrist pin bushings from aluminum bronze once I don't recall it being difficult to machine. Since it is available in tubes I just bored and turned them to size but drilling the lube holes was no problem.
I'm not sure why you're being so coy about the purpose of this device tbh, as soon as I saw you prefabulating the baseplate from aluminite, it was obvious that you were making a turbo encabulator! (admittedly, when I saw the brass part initially, I thought it was just going to be an alignable containment shroud for a flux capacitor 🤷♂️)
Interesting design choice for the magnetic field line convertor shrouds. I find the shapes and arrangement of the channels for the active and passive dielectric materials quite novel. Your client must have done a fair number of calculations in order to get the crossover thresholds of the hysteresis events to remain in sync throughout the variations of the flux amplitudes. I am not surprised at all, that you didn't show the ferrous cores that get inserted into the square cavities of the brass shrouds. Their shape would have given away the purpose of what you where building and we wouldn't want certain actors to get their hands on this kind of technology. Be safe. 😁🧡
My uncle and I scrapped (by committee) a large bronze blank we were cutting a 4 inch deep 2.5" double lead 3tpi internal acme thread into over a simple error in post editing, cam refused to specify a multiple lead, and we forgot to double the feed after adding the multiple lead word into the canned sentence. CNC does not suffer fools.
The last thing I'd call you is a Cheapskate. I love to see people recycle tooling, repairing things, or making their own. I've worked on a garbage truck and seen how wasteful people can be. It's almost sickening. However, the one thing better than free stuff, is being paid to take it.
those are not easy looking parts. I would never attempt manually. The industry has changed so much as cnc has become standard that in most cases it would not be possible to make money doing these parts manually

Admitting to your own mistakes is something an experienced person does. With that said, those parts look absolutely dead sexy. Wonderful work as always.
nice work Stefan, late night over here in Australia, and I was looking for something to downwind to. Picked up a few nice tricks from that as well.

Excellent. I always learn at least one thing from your work. This time, I got tired counting. Thank you again!
Stefan, you certainly do get to make some cool parts. These are really cool and I really enjoy the manual process. (I am not a CNC guy by any meansl).

We do the same in electronics prototyping.... 1 to use, 1 to blow up and 1 more just in case. ;)
@@edgeeffect yeah except quantity pricing makes it 1 to use 1 to blow up 1 extra and 7 more cause 10 costs the same as 4 so why not
Great video 👍 So much advice and whys you did it this way and not that way,and even your father asked why not CNC 🤭 it's only brass.
I usually resharpen the top surface of dull inserts slightly with a diamond file to get some extra life out of them :D
Great work again Stefan excellent video.

Yes, that would speed up the process quite a bit - in hindsight you could probably cut 4..5 theeth at the same time.
Ah the good old manual power feed on the rotary... A man after my own heart.
Hello, great video for diner :) Question about the face mask at 31:30 minute : is it because of the mist coolant or something else ? thanks in advance
Ahoi!
Yes, that was because of the cooleant mist. Dont want to be near it for to long without protection.

Never have I wanted a customer of yours to allow you to fully spill the beans on a part this much. These parts are wonderfully weird!
Almost looks like the side shield for a GNSS positioning antenna
Thank you Stefan.
"Parts for Arts sake" .. I like it
Went and bought Pringles spicy chorizo chips to watch this with. I like the long format videos.
Stefan - have you ever found a good use of the 120 degree corner of the CCMT inserts?
There is a tool that allows you to use that angle for deburring edges and lead in tapers on shafts for smooth seal assembly.
I have a lathe tool that uses the 120° corner for facing (And the long edge for chamfering).
Art indeed. But far more interesting than a art gallery.
I've been wondering for a long time if there's any scrap market for chips......
yes, absolutely, they get sold back to the scrap place. Esp. with brass very important, as its expensive.
Could you use an end mill, in a grinder fixture, on the lathe, as a possible solution to the issue you mentioned? I guess that might require a fairly low spindle rpm? Wouldn't your motor controller allow that? I don't recall you describing the motor setup on your large? (My bad wenn I habe dass vermisst) M f G'n
yes, i didnt have that setup with the toolpost spindle back then - i might have used it.
Unbelievably complicated! Only one mistake is remarkable, actually.
Stefan, can you tell me your experience with drilling 954 aluminum bronze? is it difficult with large drills? thank you.
Sorry, I have no experience whatsoever with aluminium bronze, apart from some minor milling work on some Amco parts.
I made some wrist pin bushings from aluminum bronze once I don't recall it being difficult to machine. Since it is available in tubes I just bored and turned them to size but drilling the lube holes was no problem.
@@bcbloc02 thanks! I'd be drilling large diameter, deep holes. I heard its tough on HSS. tools so i'm a bit worried.
amazing.
Don't underestimate the value of swarf. I know of at least one Ferrari bought with scrap!
Yeah, I collect some metal swarf/scrap seperate and sell it (Brass/Copper/Aluminium)
Some kind of dish antenna feed horn?
Yeah, antenna was my thought as well. looking at that baffle thing.
Is that a ceramic tip on your dial test indicator ?
yes, that was a 3mm Zirconia sphere.
Thanks for the explanation on a method to cut the gear teeth. Dammit now I need an indexing head for my router 😆
Damn the second guy! 😆
CNC? 'THANKS DAD! ' ;-) good ideas can come from anywhere!
I imagine what the comments'-section would have been like, 10 years ago, and I can't help but snicker. _So much innuendo-gold here_ ... ok, brass.

Stefan, are you interested in buying a Carl Zeiss Jena ULM 02-600 located in Romania?
Enjoyed watching and learning. Thanks for the look.
I never realised that so much work went into cookie cutters!
Paul, I’d like to see the cookies they would make! Lol Probably would taste great too.
sounds like it's about time to set up a little foundry furnace and start casting your own brass round stock out of the chips, lol.
Suprisingly, I dont need another rabbithole do go down :D
(I sell the chips back to the scrapyard, thats very cost efficient.)
thank you, regards r.
Grabbing a piece of torched metal with bare hands?!?! What is your skin made of?
Its just "warm", that was enough to make it slide off the arbor
nice
It's need the "Tubular Bells" soundtrack playing in the background.
