Titanium screws for Fluxcapacitor

[@OperaBass3]

Story time: One of my mentors was Bob Gardiner. Great old guy for a young apprentice to aspire to. His specialty was running the Monarch 10 EE making small to tiny parts for the top-secret requirements of the director shop where chronometers and odds and ends of gun and missile directors were looked after by weedy looking techs with suspicious eyes. He liked me for some reason and took me under his wing when I was an apprentice and after we developed a close friendship. We developed some performance art we'd put on every few months. His specialty involved working a week making a handful of tiny parts having many precise features generating enough chips to almost fill a coffee cup. When we'd meet at the coffee machine I'd give him a big vertical boring mill chip weighing more, perhaps that his entire daily output saying: "That's the kind of chips a real machinist makes." Bob gave as good as he got declaring a heavy tool machinist was no better than a coal miner and how anyone could shovel chips but a real machinists did precision work. If we had an audience, we carried it to a belly to belly shouting match, seemingly heading for a fight. A tiny man in his sixties trading violent insults with a hulking brute half his age looked like an impending disaster and a mountain of disciplinary paperwork. New bosses hurried forward to intervene and the women and visitors within earshot stepped back. Those who knew us nudged each other and grinned when the invective got particularly entertaining. When the tension rose to the breaking point we'd have to laugh having getting applause from our workmates and dirty looks from the duped. The point I think I'm making is the machinist's trade is wide and deep covering every sector of machine work from manufacturing on the largest scale, to mass production, to small batching the delicate parts you demonstrated and everything in between. But the steps and care, while different in scale, are almost identical and you demonstrated all that's applicable for the work performed in this video. Fine presentation where every step was individually placed in sharp focus much as Bob Gardiner illustrated his methods to me for running the EE. Thank you.

[@CaskStrength777]

I don't even make chips anymore.... started a general machinist in every material from steel to plastic to carbide, went to school for watchmaking and learned watchmaker's toolmaking and very tiny chips like your mentor. I mostly make a thimbleful of tool steel sludge everyday now running EDMs as a tool and die machinist, but still do manual stuff at work, and tiny precision stuff at home. Guys like you and Steffan are who I aspire to follow..and surpass. Cool story

He could tell us that, but it would cause a causality loop paradox so best to just say it is for a flux capacitor. Stephan is kind to not implode our timeline.

[@imagineaworld]

Thats all i can ever ask of my physical abilities x)

[@StefanGotteswinter]

Cant fault you for that :)

[@EdgePrecision]

One thing that I have used for deburring small parts is plastic brushes made by Weiler. They make some with very fine abrasive filled bristles. Holding the part like you were doing in your chuck. On a slow speed buffer (slow speed is important). You can just bury and rotate the part in the soft bristles. The wiping action of the bristles micro radius's the corners. It's been a long time sense I have use one but 800 and 1000 grit in silicone carbide abrasive worked the best. (That is if they still make them).

[@StefanGotteswinter]

Thanks, I will definetly look into them - I have a large abrasive brush that I chuck in the lathe, but thats a bit agressive for such small parts. Is it something like the small 3M bristle brushes?

[@EdgePrecision]

@@StefanGotteswinter I have never used 3M brushes so I cant make a comparison. These are very soft brushes. I would say the bristles were about .5 mm in diameter and around 38 mm long. We use to run them on a slow speed Baldor buffer 1700 Rpm. When they were running you could press your fingers into the brush with no problem for short periods. The Idea was not to wse the tips of the bristles as say with a wire brush. It's the wiping action of the bristles rubbing along their sides that does the work. It is important not to use the same brush for all materials. For instance don't use the same one for carbon steel that you would use on stainless or titanium. It would leave a steel residue. These brushes look dark gray in color. www.weilercorp.com/metal-hub-wheel-brushes-20600 look at this link. The finest grit I saw on their site was 320. Maybe they don't make the finer grits anymore. Or maybe I don't remember correctly.

[@lamprax426]

@@EdgePrecision I don't know if this is anything similar but it says 1000 grit www.weilercorp.com/composite-hub-wheel-brushes-83004

[@Gottenhimfella]

@@StefanGotteswinter Do you ever use the pantograph for deburring? If you changed the stylus and used a rubber abrasive point, you could debur the entrance to the Tork recess, for instance.... But I have previously used one also for chamfering all the edges of a part, using a chamfered part as a master. Great for plastic parts in particular...

[@robertburns2415]

Being a machinist of over 40 years of experience I find this video edifying. One suggestion I have is a time frame 15 minutes you get within a millimeter of the chuck with the tool. If you offset grind the point of the tool 1-2 mm off the left-hand Edge rather than in the center of the tool it will give you the extra room you need to prevent a collision. Other than that I haven't seen anything in your videos that I can make a suggestion on well done.

[@Ujeb08]

? do you read over what you write?

[@robertburns2415]

@@Ujeb08 I did misspell a word I ment to say chuck. For the people who don't know, word edifying means valuable information or instruction, which is what your video has. I'm very impressed with your knowledge. As to the threading tool it would look something like this. A AAA AAAA AAAAA AAAAAA AAAAAAA AAAAAAA AAAAAAA AAAAAAA

[@RRINTHESHOP]

Wonderful work there Stefan.

[@StraightThread]

Fascinating to watch, Stefan. I imagine the customer is going to be greatly pleased. Great lesson on making a high-precision part.

[@coy3570]

Wow,great to see you machining some Titanium in your shop!you really inspire us

[@Hoaxer51]

Who ever you make these parts for, I’ll bet they are happy as Hell they found you! The precision is unreal! Nice job!

[@fristlsat4663]

This precision isn't unusual, it is just expensive. I expect this type of work is for experimental things, or R&D or process development. When stuff goes into production it will get sent to a volume job shop where they do the same stuff, but with more computers and less Stefan, and price per part is many times cheaper. You just have to have the Stefans to get from paper to metal and prove the thing you designed actually works. It is cheaper to pay $100 a screw or more if you buy 20 of them then figure out they need to be just a bit different. When you need hundreds or thousands of them for a production device that same $100 screw may very well cost a couple bucks or less, because then they aren't special, they are production. The best part of Stefan's videos is how clearly the fact that he cares comes through. He obviously cares that his pieces reflect the extremely high standards he holds himself to, even for stuff he isn't selling like his spindle switch handle. Me, I woulda whacked that out of a piece of aluminum entirely fit by feel, probably never measure anything, but he drew up a model and printed the thing to fit precisely. Probably spent more time and effort measuring where it had to fit than I would have spent on the whole thing, and look, it shows.

[@paulraterink7331]

Hi Stefan, just finished watching the video you and John Saunders did during his trip to see you. What a wonderful and likable person you are, and the knowledge you have about so many tools. I watch all of your videos and always learn so much. Keep up the great work with your videos and sharing your knowledge. All the best, Paul

Excellent. That collet chuck on the Emco is interesting. Like the spindle cover. Just a wonderful video.

[@owensparks5013]

Having become used to how everything is "awesome" to such an extent that the word becomes meaningless it's wonderful to hear a German describe something as "decent". Instant channel sub. 👏

Stefan, your relaxed demeanour is a real joy to observe, especially when demonstrating such small and delicate operations. A toolmaker's toolmaker at work! Have you considered a 5/16 Geometric Die Head for cutting those small threads? I have one, and it makes the production of small threads a breeze. Gruesse aus Canada.

[@bobengelhardt856]

34:00 - checks thread, again, ... "perfect". No, I don't believe it! It's never perfect for Stefan. This is a first! Oh, wait ... a few seconds later he gets control of himself & calls it "decent".

[@outputcoupler7819]

I know Stefan can't talk about what these are for, but they look suspiciously useful to applications involving pressurized gas.

[@MrLukealbanese]

[@danielmorgan4445]

[@canberradogfarts]

Can you describe, show us how you center drills, THAT SMALL, to the center axis. Thanx.

[@imagineaworld]

This. Plox.

[@geoffmorgan6059]

My question, too. You are working to (near) microns and anything off axis will result in out of tolerance diameter or worse, drill breakage. Plus, is there any repeat problem with the QCTP? Thanks.

[@windsoruk]

This is my question too - I have a couple of taper tool holders of that type that fit on the QCTP, but they are a lot of trouble to set up so I very rarely use them.

[@bigass197]

probably EDM

[@AntiVaganza]

It doesn't answer the repeatability question of the QCTP, but he mentioned he had the center drill tool stored in the DRO, so I reckon he has the ER shank tool which he uses for the drilling stored, too. And that when storing the tools in the first place he indicated them from the chuck. Still, a good question and I would think the QCTP is very repeatable as I don't think the would indicate the drill tool every time he drops it is - given that he has some other smart, time saving ideas in his work flow such as the center drill and chamfer tool being the same.

[@tinygriffy]

Sehr fein ! (wie so ziemlich alles was ich bisher hier auf diesem Channel gesehen habe) Lehrreich, unterhaltsam und teilweise echt erstaunlich, Danke !! Das Teil erinnert mich irgendwie an ein Feuerzeug Ventil ... ein GTWR Feuerzeug ginge bestimmt weg wie warme Semmeln ;)

[@Stephen1455]

Beautiful lathe fixturing, just retired as Master Instrumentmaker and used lots of emergency collets, but this brilliant!

[@465maltbie]

When I have to debur small parts like this I find it easier to mount the Dremel tool in a clamp and hold the part. Use it like a little bench grinder. Thanks for sharing, very nice description of your process. Charles

[@janvanruth3485]

i would like to see the setup of making the torx on a manual

[@StefanGotteswinter]

In this case, on the engraver, using a 20x template. On a normal 3 axis mill with a rotary table it would also be possible, but take forever.

[@iaahner]

A rotary broach would probably be my first approach if I wanted to do it on a manual machine.

Hi Stefan, Very nice work and learning a lot from watching you. I have the same lathe and like the idea with the collet chuck guard and main switch modification. I will make that switch modification to mine. Collet chuck will be in the future. A thought i had but haven't looked at how to do it is to put a spindle lock pin somewhere. All the best and keep up the good work Paul

I’ve never cut titanium, but you make it look like butter...

[@GeneralChangFromDanang]

It is like butter. Butter that comes off in long stringy strands that get in the way of your next cut and drag along the entire length of the part and ruin your once perfect finish.

[@peterjones6945]

Stefan, you are incredibly patient to do all that work, Titanium isn't the easiest stuff to machine but you made it look (too) easy. It must be a very expensive piece of equipment as those should be very expensive parts. (CERN involved?) I would also like to say, I find your calm commentary and the video's very inspirational, I actually got my Harbor freight 3 in 1 working again after watching several of your video's (very cheap Chinesium construction but, it's what I've got)

[@k5at]

Great video. Stefan! Great attention to detail!

[@nicktohzyu]

20:30 why didn't you mill the hex first, then hold that to turn the threads??

[@StefanGotteswinter]

The concentricity between the two threads was critical - Milling the hex and clamping on the hex would not have helped holding close tolerances.

[@nicktohzyu]

@@StefanGotteswinter why? isn't there the same uncertainty between holding a cylinder vs holding a hex?

A good way to grab those parts when paering off would be to catch it in a plastic soda straw, assuming you can still even get those in Europe. I heard they were (or at least trying to) outlaw them... I have just spent over a half hour watching you machine parts I can barely see... It seems kinda crazy when you put it like that, but very cool nonetheless. I wonder if anybody else watched these /tiny/ parts being made, and kept expecting to hear: "Hi, this is Chris from Clickspring..." I think these parts may be smaller than anything I've seen him make (or at least can remember). Very cool watching you make small parts. I am amazed.

[@StefanGotteswinter]

Yes, because we sit on a ridiculous pile of one-time-use plastic crap. But catching it with a piece of plastic tube is a good idea. I wish my videography was half as good as Chrises. And thanks for watching!

If you drop one of these screws into the bilge, you're in big trouble 'cause the magnetic retriever thingie won't be much help and you can't just pop down to the local hardware store for a blister pack of spares. I'm in awe of your craftsmanship and thank you for sharing it with us.

[@clintchapman4319]

I admire your skills Bud!

[@gospelman7222]

Stefan, when deburring small parts, have you considered using a flexible drive instead of grasping a somewhat large and unwieldy drill body? I have one made in Germany by Proxxon , it's little bigger than a pen and so convenient to use.

[@StefanGotteswinter]

Yes, I am looking for a flex-shaft motor and some accessories like a Diprofil-Filing machine.

[@agie170hss2]

Stefan, on the close-quarters threading, did you consider turning the tool upside down and threading away from the collet?

[@unionse7en]

Please shows us where to get that loupe type optical that you have mounted.

[@Ujeb08]

Nice! You made this look easy! I wonder what grade of titanium these screws are made from? Because grade 5 titanium is infamous for work hardening and breaking tooling. Especially that very small drill which you had set up in the tool post. That in itself must have been an interesting alignment procedure. Maybe you could do a video and include alignment and centering a tiny drill into a tool post on the lathe???

[@TheJoyofPrecision]

Next-level screw making, I love it!! 🙂

[@Sketch1994]

Threading in close quarters is always stressful. The worst one I encountered was an internal M10x0.5 trapped between a 10H7 guide bore and a 10H7 flow surface that continued to a 90 degree taper until meeting a 2.5mm to 1.6mm 5 degree taper. No thread reliefs were specified and did I mention the required Ra=0.8mm surface finish? That was a really bad design as the major diameter of internal threads is larger than the nominal size. This could be improve by enlarging the OD (had 0.5mm walls) to make room for a M11x0.5 thread (odd huh) in front of the internal profiles which could then be all be done with a single form tool and the thread could be just tapped. It probably looked good on paper to the eyes of the intern that designed it...

[@chuckbuckets1]

could you deburr with a tumbler and some appropriate media?

One thing for sure this stuff ain't cheap!

[@magnusklahr8190]

In terms of safety your 3D printed forward/stop/reverse handle may have an issue because of the risk turning on the lathe unintended when getting caught at something when e.g. passing it...

[@CaskStrength777]

I like your use of custom ruby stones, and especially cratex sticks for fine thread deburring. We used cratex wheels in watchmaking school as part of case polishing to make line finishes in certain areas, and I know of their use in medical part deburring in other industries and similar materials I deal with.. Very cool as always. Where did you get the ruby stone?
