Making a part: Stainless Steel Guide Frame

[@TandaMadison]

Really enjoyed hearing all of the, "why I chose this approach" and tips. Always some good information. Excellent work as always.

With all the floods in Germany, and with Stephan not posting anything in a while, I was getting worried he'd been washed away. Glad to see you are OK, and posting videos!

[@sblack48]

From the pictures on his Instagram it looks like is on high ground

[@MultiArrie]

Stefan lives 300 Km or so away from the floods.

[@tonywilson4713]

Agreed on the sentiment. Even if he's away from those areas, the fact people care matters. I'm Australian and we've had our fare amount of similar issues with mother nature in recent years and those sentiments do matter.

I used to work in a maintenance / machine shop, there were 7 of us; Pipefitters, Electricians, Welders, Painters, a bunch of multi-skilled workers, helping to keep a Victorian era Mill running at the end of last Century - then there was Old Jim, a semi-retired, soft-spoken, apprentice-trained machinist, who had joined the company from school. He spent a couple of days a week fabricating and machining replacement parts for 100+ year old Jacquard looms and I can't tell you how many hours the other 6 of us used to waste just watching him work. The finished piece wasn't always a work of art, but the process was always a joy to watch, just like your videos.

[@ManicChampion]

Machining is great; I would recommend it to any young men looking for a job. The more manual machines you get to use the better, even if it's harder and more dangerous, you just experience the joy of it more.

[@mhc6777]

Thanks again Stefan - I really appreciate grown-up machinists like you who share your thought process during the project rather than just showing what you've done.

[@gerritvisser]

So many small tips and hints that end up making a large contribution to my skill set, thank you.

Woohoo, a new video!!!! I have only just discovered your channel and I have spent the last week binge watching all your videos. Thank you for hours of entertainment .

[@Watchyn_Yarwood]

He's the best!

[@bobvines00]

Stefan, please continue making these "Why I chose this approach" videos! You can't explain too much detail about what _you_ do and why _you_ do it. I learn a lot from this type of video. I worked as a Tool Designer when I started my Engineering career and spent a _lot_ of time working with our Toolmakers. Unfortunately I couldn't run the machines to make my own designs, but by watching closely and asking a _lot_ of questions *and* taking their advice when appropriate, I became a very good Tool Designer. Now that I'm retired, I have a few small manual machine tools and can use the "lessons learned" from videos like yours to improve my machining skills. I really wish that I had been able to go through a Machinist Apprenticeship program, but watching excellent Machinist-type videos is as close to that as I can get!

[@ROBRENZ]

Good stuff Stefan! ATB, Robin

[@bcbloc02]

Some machinists like to leave certain tool marks. Stefan likes no marks at all. The art is removing all the tool marks and not making your part go out of spec. :-)

[@StefanGotteswinter]

Yep :) That gives more of a "product"-look, i guess.

[@NarfBLAST]

@@StefanGotteswinter Speaking of "product" look, the plastic packaging at the end of the video is a very nice touch! I really love all the detail you put into your videos and can never get enough. Thanks for the longer video, thanks for taking the time to share.

Impressive work. Thanks for the video.

Loved the Scotchbrite tip. Thanks for the detailed production making the part.

[@mikemichelizzi2023]

I really appreciate your letting us look over your shoulder - always something new to learn. Thanks!

[@HansFormerlyTraffer]

Thanks for showing stuff like squaring and deburring...we novices appreciate it.

[@djizomdjinn]

That's a really nice finish for a milled radius! I did something similar recently, but my radius had a shoulder at one end, so I locked my x-axis and just used the a-axis... at which point I learned that endmills are not flat at the cutting end and i'd machined a tapered bulged cylindrical feature. Ah well, I managed to get it to work out in the end, so file that one under "learning experiences". Great video!

[@ActiveAtom]

Welcome back, we missed and flood wise worried about your wellbeing even though we do not know you we love your channel and your great detailed videos so very happy to see this video today nice ending grinds. Lance & Patrick.

[@zachaliles]

I have a feeling you know when you're subscribers are randomly binging your old videos. Because every time I'm on about day two or three of doing that you post a new video, hahaha! Can't wait to see what you've got in this one.

[@frithjofhudepohl5731]

I want to thank you for all the plethora of videos you offer to who ever is interested in learning. I especially enjoy your building of tools like the jaws for a chuck, or the offcentre chuck, and the likes. I want to ask you, though, if you could someday put up videos about things that didn't work. Like when you later found out that a particular tool was not a good idea and why. Or when you did an iteration over a tool to actually make it work or eliminate its flaws. And of course always with your superb narration and explications as to why it didn't work or what your thoughts were on the redesign... I realise that for you it wont be very exciting. So don't feel bad about dropping this whole request in the bin... Please keep up the fantastic work and effort, and thanks again.

[@johnnyryall1400]

I love how you make the explanations so easy to understand for a non machinist. Also, your English was never bad, but it’s gotten excellent.

[@robertburns2415]

Very thorough explanation of what you were doing. I've been Machining 40-plus years I can't add anything to your evaluation. However the photography was so good that I felt like I had to put on safety glasses. PostScript I just subscribed

[@mpetersen6]

Whenever I was handed a new job from my boss the first thing I did was to make photocopies* of the drawings. One set stayed clean. The other set I used for all my math, job notes, program #s** etc. *does any one say Xerox any more? **I kept all my jobs on 3.5 floppies as I would never know which machine would by open. No USB ports for flash drives on our Trak or Anilam controls. The program #s were recorded along with the drawing #. I also used to do a bit of helical gear cutting on a Barber-Coleman Series 16 gear hobber. A normal gear hobber the work and feed ratios are easily set. The work ratio is simply the # of teeth decided by the base ration of the machine. We had gears for both banjo set-ups from 22T up to around 80T. When cutting helicals the Index and Feed ratios are calculated using a constant along with an offset depending on RH or LH helix and hob. Once calculated and factored I always wrote these down. Especially the feed gears. Of course now there are online gear train calculators that will do it for you. I was also responsible for rebuilding precision spindles for 4 years. I had one of those Sony digital cameras that used floppies. Any thing out of the ordinary got photographed and the floppy stored. I had a lot of floppies

[@captcarlos]

Another master class from the maestro. Thank you Stephan, many techniques to absorb.

[@Joelsfilmer]

Dammit, Stefan! Not the open pen in the Tabellenbuch again! My heart can't take it twice.

Master craftsmanship, ISPO dimensioning lesson and a very nice rotating fixture setup all in one!

[@TheUncleRuckus]

Love the Scotch-Brite pad trick 👍👍

[@FinnoUgricMachining]

It's all in details. I also have good relations with the SK30 tool holders. I didn't know about them until I purchased my Schaublin SV-51 milling machine that has this, back then exotic, spindle. Later it has proven that it is not that exotic after all. That arbor in the dividing head. I quess that it was made in the same dividing head as it was used. Probably never leaving between it was made and used. That fuzzy Scotchbrite had a habitus which made it impossible to identify the material. Self centering indeed. Thank You for Your time You have used to put this show on the road.

[@MichaelMoranGearHead]

Thank you! That was a great collection of tips. I love that method for cutting the crown radius. I know I'm going to use that in the future.

[@mpetersen6]

Turning parts in the lathe that require special arbors. We had a number of repeative jobs that required such set-ups. One was chuck jaws for machines that faced, turned and cut the ring grooves in pistons*. Another was locator pins for the wrist pin end of connecting rods that could be rotated 180° so the machines could be changed over to a different rod length. The chuck jaws came in as investment castings with the final operation cutting the jaw serrations. The locators had a 1" base diameter with the locator diameter offset .125". Hardened and then ground of course. *spent 30+ years in an automotive engine facility.

[@chrisoftceo]

So amazing to see all this manual excellence in such a level of detail. Always amazing to see a true master of it's craft!

[@shawnhuk]

Fantastic video, Stefan! Really enjoyed the thorough approach. I definitely learn more about how to attack tricky processes when very skilled individuals share their thoughts.

[@calvinjutila8270]

Clear and concise description. Great work

[@toolbox-gua]

Glad to know You are OK and safe from nature in Germany. I was expecting the mill of the large radius to be turned on the same arbor, not longitudinal and avoid the facets. But then I know nothing about machining and You are my master.

[@patwicker1358]

Thank you for going over the details. You are the most efficient machinist I know I learn a lot from your details.

Small, precise and on the numbers. Amazing as always. Loved the scotch pad tip too!

[@uberente]

the scotchbrite wheel is a fantastic idea, i'm going to be setting one of those up as soon as i need to finish something. my go-to for finishing bores is a 1/4" rod with a slot in one end, where sandpaper lives until it falls apart, but that's not so great for surfaces =D

[@joell439]

Truly appreciate the apprentice details. We have so much to learn from the master 👍😎👍

[@bigwave_dave8468]

I spoke with a gentleman who ran a large shop and he told often times engineers will specify 304 stainless because that's what they know about - he would often recommend 303 if they didn't care as it is easier to machine.

Great video! When I saw the top of the part was convex I was sure the Emco was going to be in the video, but you gotta love the rotary table. Those scotchbrite Dremel you can get from China for pennies. I got 100 each of fine, medium and coarse for like 20 bucks....

Wahnsinn, wieder mal Stefan! Von der Qualität her könnte das locker ein sehr gutes Lehrvideo für Zerspaner und Feinmechaniker sein, die Schritte so detailiert dokumentiert und dazu die passenden Erklärungen, einfach toll anzusehen. Ich bin jetzt 10 Jahre im Zerspanungsgeschäft und war vor dem Video sehr gespannt wie du den Außenradius fräst, hier lerne ich selbst wieder dazu! Da ich viele Einzelteile fertige, auch oft "komplex" und zeitintensiv würde mich interessieren wie viel Zeit du insgesamt gebraucht hast für die vier Teile, inkl. Planung, Aufspannvorrichtungen erstellen, etc. Das sind ja schon sehr aufwendige Teile, meine Kunden denken oft das soetwas mal eben am Sonntag zwischen Frühstück und Mittag entsteht. :-) Das dem nicht so ist wissen wir Beide sehr gut. Liebe Grüße und vielen Dank für das Video!

Stainless steel is a pretty unpredictable material at the best of times, I was machining some 316 trunnions for a Nuclear transport flask, they had a 600mm square base 200mm thick with a mushroom shaped stem on top , I roughed the mushroom shaped out and come in the following morning to find that the mushroom cap was running true but the stem was 1mm out of true, had the Engineers scratching their heads for a while, fortunately there was enough material to make good.
