As a 50 year sheet metal worker (13 years retired), I humbly thank you for the kind words❤
When you said sheet metal workers are magicians. I thought of Ron Covell making a dustpan for This old tony and himself. Great work Stephen.
Ron Covell is incredible, square to round sheet metal forms, 1 piece ally race car seats, what a ledgend👍👌🇦🇺
Ron Covell is a wizard with sheet.
@@crabmansteve6844, I wanted to say that he’s a magician with metal, if I ever want to feel inferior, I just watch some of his videos, especially after doing some metal fabrication. Lol
I'm actually the guy perpetrating the myth that 40 taper is self releasing, I've been working really hard on spreading it around!
thing about it, it seems to have stuck!
Any taper will self-release if you’re counting on it to hold.
@@jeremylastname873 Unless you're shortly to appear in a NTSB or USCSB video.
Stefan is coming for ya!
lmao
When supporting sheet metal for milling, the support material doesn't need to be perfectly flat. Even OSB is close enough to "flat" of the cutting tool extends deeper than the deviation from flatness of the supporting material. Once it's unclamped, the sheet metal will return to its original degree of flatness.
I agree with your assessment of sheet metal workers. I did sheet metal work on light aircraft at a point in my life. I was "pretty good" at it but the guys that were perfect at it were truly amazing. I knew one man that took measurements on an airplane under construction near Houston, TX. He went home to Omaha, Nebraska and built the turtle deck for the airplane. When he was finished he shipped it back to Texas. Even the Dzus fasteners were in place. It fit perfectly. He was a magician with sheet metal! You were awesome, Jack Furstenburg!
Great show! My father often said, 'an ounce of prevention is worth a pound of cure'.
Today's video from Stefan: "How a Master Machinist approaches sheet metal work" Wonderful stuff Stefan! It's always a pleasure to watch you work and hear your thought process of how you achieve such fine results.
Great video Stefan! If anyone struggles with getting the fabric to hold tight in the pinch clamp, you can do a little loop around a piece of thin wire and an appropriate groove to clamp all the way around. Think like piping on upholstery or the like :)
Very nicely done Stefan! It should last forever now.
ATB, Robin
What are you doing here Robin?!
C'mon, hurry up, you have an _optical pitch lap_ video to publish!
Thank you, Robin! Your Hardinge Covers greatly inspired this version :-)
About sheet metal workers:
an old man once said to me, wrestling with a well-kept 5000-year-old lathe: "Humility and knowing your limits saves a lot of work and material."
Good philosophy.
Excellent video as always. Love the sheet metal work tips. But did no one else see the advanced doorstop in use at 6:15? Flip flop for the win.
Thats not a Flipflop, thats a proper Birkenstock, my good sir! :D
@@StefanGotteswinterLol I'll concede that is way classier.
Stefan towers over most machinists. Like. He’s a tall fellow. He’s talking lathes but I wanna talk about music with him. This gentleman is an ambassador for metal. Also he likes guitar music I think.
Seeing Alestorm on the back of his shirt halfway through the video hit me like a flashbang.
@@microwave221 haha I kept trying to pause and read them. Thank u
Stefan what you could do is to put and Engine turning finish on the guard to match some of the other parts on the lathe. Also I like your door stop. LOL
Your last vid on this topic inspired a stainless guard for my lathe, i love it. Looks great too👍👌🇦🇺
Milling the sheet metal to the final dimensions on the mill is super therapeutic and satisfying
For the way and table protection of my lathe and mill I used belting from old exercise treadmills. It cost me virtually nothing as I had stripped the treadmills for the motors. It is much thicker and can cause problems when working close to the chuck but the thickness adds a substantial margin of protection against impact. Handy when you are talented clumsy. The belting also has a nice woven material backing that slides freely and does not seem to hold chips. The belting seems to be impervious to anything I have used near it.
Pask Makes uses that technique to bend sheet metal a lot and he always gets great results. Nice to see you use it too!
Very nice build. An alternative to sanding the sheet metal would be engine turning. It hides a lot of scratches and sins. Look forward to your next video.
A very neat solution - excellent execution of the idea. 👍👍
The best fastener is a perfect fit with no fastener. Bravo!
Oh yeah random orbit sander work really well to create nice pattern on hard material ! you can use it on plexiglas to create simili frosted glass too
I have the same Bosch random orbit sander. It is a great tool. Also very nice to use with compressed wool for polishing with 3m compound….
You are right, the neat look is important.
For those interested in the McMaster part number, 8811K55.
I plan to do the something similar to my lathe.
Thanks for the content Stefan!👌🏻
Hello Stefan, the results speak for themselves - what a nice looking addition to a nice looking lathe! 👍
Thank you Sir!
I always find it funny watching machinists do sheet metal work. Stefan is a master of his art, but speaking as a welder/fab of several decades experience. I'd have guillotined out the blank marked it out on a height gauge, death wheeled, and finished ground to the line with a small 90 before he'd have jig sawed out the hole, and I'm disappointed if I can't hold 0.1 like this.
I wish I had room for some nicer sheet metal equipment :)
At my former dayjob we had nice hydraulic plate/sheet metal shears, corner notchers and manual bend brakes - Made always quick work of stuff like this.
As always, over the top and fantastic.
Thank you Stefan.
Thanks for the last couple of tips, that's what makes you such a great instructor. Cheers from Sweden
A bunch of good ideas and techniques in there. Thanks. I live an hour south of McMaster-Carr's Los Angeles location and have been there in person a few times :-) It's just a walk up counter, though, and a GIGANTIMOUS warehouse behind that. Also I can order things at breakfast time and they deliver after lunch. Amazing company. Awesome website.
Always a pleasure to watch, thank you!
I have the accordion/bellows material on my Hardinge HLVH. It is effective, however the bunching is horrible with it. It looks like the neoprene coated fabric does a better job. Since I’ve done a bed regrind, scraped the cross slide, bonded Rulon to the carriage underside, I’m pretty picky about keeping it pristine. I’m going to try that material out. Thanks, and nice work, as per the usual. Cheers from Florida’s Space Coast.
Beautiful and professional craftsmanship as always 🤩
Very nice work! Also, it makes me glad to hear some machine maintenance sensibilities being voiced out... `s always a pleasure dropping in over here!
All the best and kindest regards!
Steuss
Another good addition to the lathe Stefan.
Well done 👍. Thank you for taking the time to share.
Great solution Stefan and the end result looks great. Had wondered about the versatility of the Deckel Milling Machine, with the table bolted to the vertical face, but your demo shows it every bit as functional as the more conventional style machines (Eg:- Bridgeport). Always enjoy your content, so please don't ever stop.
As always top notch work Stefan 👍. If you didn’t notice, I wanna point out to us Americans that this 33:14 +250 is in centigrade. For us who are still using the stone age system of measurements, 250°C = 482°F 😁
Thanks!
I can wrap my head around inch/foot, but Fahrenheit kills me :D
Ahh, the BirkenStop!
Must be Spring in Germany.
I don't know if the sheet metal could take it or if it would last, but doing some engine turning on the guard to match the apron would look really cool.
Stefan, thank you. A hydraulic chuck? Never heard of this fantastic tool holder. Not too terribly expensive @ ~$550USD depending on make. I'm running BT30.
Very nice. A really good fit as well. I've made some openings in metals sheets and usually the openings end up being a bit too small and some more filing takes place, haha. I am not a machinist, just have some basic tools (drill, jigsaw, dremel and a file). The one things i have learned from machine CZcams channels like yours is to always de-bur. That is something i can do. Thank you.
if u ca nget anything, get one of those small lathes .. I just got one (before the large one, to train and get familiar with it) and it is just way way different to before without one. It's one of those 180x300 (mm) types.. mine is a optiturn 2004v. Can recommend. Expect to spend 50% of price on tooling (but that's for any of those)
Great work,Stefan.Thank you.
As legochamp1 already pointed out, "Teichfolie" is also a pretty good option. I use it on my CNC machine. It is very durable and can handle hot milling chips. Greetings from Badischen, Stefan.
Thank you for this in general and for posting it to match my dinner time particularly!
It turned out sweet, nice job👍
Excellent as usual!
The sheet metal cover came out Mint! Nice job, Stefan.
Good evening Stefan, just saw you have released a new video. Nice
Great video as always. Thanks
One thing about using any kind of wood as a substrate is that it will absolutely move if you get the fiber wet and wait for a while. So, get in and get out if you’re using coolant.
I believe the Anchorlube is soap-based, not unlike some water soluble commercial coolant / cutting fluids. It’s a good product, replacing various old standbys (TapMagic, etc) in my shop, though I still reach for the brush in the oil pot much of the time. Habit !
Stefan, you'll find that while anchor lube is good, it really shines when you're tapping. It's phenomenal tapping lubricant in my experience, especially power tapping.
Good one Stefan !
I tried using RV membrane elastomer fabric roofing material as way covers.
So far working quite well it's tough material but flexible and can be purchased in small quantity's at reasonable cost.
FYI
Thank you for more great content.
For slightly thicker occasional Sheetmetal work there are some good affordable brake options for your little press. I have a heavier solid one for mine but picked up two sets of 200mm magnetic vice jaw ones to make a flexible 400mm long pan brake for my larger press for Sheetmetal work.
Dammit Jim! I'm a machinist, not a sheet metal worker!
:D
Thanks for the video keep on keeping on.
Fantastic...enjoyed...Thank you!
I'm actually not too sure about leather for way covers; I've noticed some corrosion on brass hardware sometimes where it touches leather, and if it happens it happens extremely quickly too, sometimes within a few days. But sometimes it doesn't corrode at all. The only difference I've observed is that vegetable-tanned leather doesn't seem to cause the same corrosion issues where cheaper chrome-tanned leather does.
From my understanding, the metal salts used in chrome-tanned leather are what cause the issue, but I'm only a hobbyist leatherworker, not a tanner, so I can't comment on the chemistry. To be safe, I would suggest using veg-tan or at least oil tanned leather.
Nice work as always thank you for the video.
And a sacrificial aluminium block is probably also a very nice heatsink... compared to wood or plastic.
I use a piece of old inner tube on my mill/drill. I got it free from a place that deals with logging trucks.
I use paint stripping discs to deburr sheet metal.
The anchorlube stuff is great, but over time it will either dry out or grow a beard of nasty mold stuff.
Any lube left on iron will cause staining spots as the stuff is water based. Clean it up and re-coat with your corrosion prevention of choice.
The blue boelube wax in a jar is superior IMO
Good to know! Thanks!
(Generaly I use a Wax Stick from Jokisch, meant for Bandsaws/Circular saws, when tapping/drilling with a handdrill)
Love the metal shirt and the videos!! Peace ✌️
Came out great Stefan, thank you for uploading! 👍👍
That incredible BIRKENSTOCK door stop is cool af. As the whole guy itself. What kind of size is it, 49? Must be a tall metal warrior.. Great as always, thank you!
anchorlube is nice stuff for the drill press. It causes rust on cast iron if you don't clean it up right away. annoying because it's generally a nice product.
I would prefer pine dust and smoke to MDF dust any day. Even more so if the MDF binding glue in Germany is toxic. Also for fun, if not profit, maybe get a plasma cutter. Mine came with TIG and stick welding. Your English is very beautiful, I do recommend Aluminium though - even if it is harder to say. Thanks for showing more of your nice lathe.
Nice! You could 3d print some corner bumpers to protect your hands from running into the front corners. McMaster-Carr also sells fiberglass-reenforced silicon sheet material similar to the baking sheet material. I'm guessing it's not as flexible as the neoprene.
Totally agree with the magician part. To solve it we bought a fibre laser and a CNC press brake 😂
another great video 👍
A properly positioned vacuum will move as much air across the cutter as compressed air for cooling but also collect those chips. Just a thought.
I agree, I have used the same idea for drilling and it saves cleanup bigtime.
Nice job as usual.
That sqare/45 corners.. Oh yes.. German school in the best sense of that 😄
Italian will made all sort of curves, rouds...
As friend of mine used to say: I beleve that in Germany rain fall in cubes, and neatly stack in the rows, waiting for it's turn to go down the drain 🤣
BTW... try to put some scotchbrite on that orbital sander (just slap it and cut the circle). Didn't tried it on steel, but on aluminium it look amaizingly good. Probably on the steel it will need come coarser grit.
It can be a bit hard to release it from the sender hook pad in finer grits, but nothing horrible.
Thanks for the scotchbrite tip! I had used it on a vibratory palm sander at work to fix some uggly machine bases, but never tried it on a random orbital.
Somewhere, Ron Covell is smiling!
Perfeito !!!
Abraços do Brasil 🇧🇷
As a Canadian hobbyist I have a similar problem with McMaster Carr. They will ship to Canada but only to schools and businesses.
Yassss
As usual, a jewel being made by a machine tool jewler😊.
Die Entgrater sind wirklich gut bei kontinuierlichen Formen in relativ weichen Materialien. Z.B. Kopferrohr. Alles andere das einen Start und Endpunkt hat muss deutlich härteres Material sein und auch da kommt es zu Beginn der Bewegung zu Rucklern. Drum empfehle ich die Startposition künstlich durch einen offcut zu verlängern. Muss man aber gut mit klammern fixieren, das Ergebnis ist dann passabel, da die Ruckler im offcut passieren und die durchgezoge Bewegung dann auf dem Material stattfindet.
Like to add yes my friend you are a machinist😊
thanks fore a very nice video
It is a simple reinforced rubber sheet.
I love Primus. And the fearless flying frog brigade. We know you’re tall Stefan. Wollt ihr das Bett in Flamen sehen? Is the best German I could muster. When will you make gongs?? B20 bronze.
Nice.
As usual. Fantastic work. Cardboard is fantastic, however have you ever used the plastic board that is similar? In the USA it is often sold as Corrugated Plastic Yard Sign material. literally plastic cardboard, that can be cut just like cardboard. . The benefit being that it works as easily and holds up longer. Not suggesting permanent, however it resists the machine shop environment very well. Keep up the great work.
There'll be a lot of it available for free in a few months too, as long as you don't mind the drivel printed on it
Yes @@gorak9000 but there is also the special moment when a sharp blade goes through the face. It's voodoo in the modern era. The main game is to collect the posters from your opponent, and, depending on personal ethics, the timing is important. Decent people wait until the election is over.
I've bought stuff from McMaster Carr's US web site a few times, using a credit card, and they shipped to the UK fine - it might be worth double-checking that they don't ship to Germany🤔
Damn, will have a look again, thanks!
good video stefan
Looks very nice. Did you observe that oil ist creeping under the way cover as there ist no overhang? just curious If this could be a problem
A bit of it seems to make its way under - But since its oil and not cooleant, I dont worry :)
Interesting. Not sure why, but interesting.
How come the cutter jumps over to the left at 16:44? Just want to let you know that we're paying attention!! Are you sure you made the covers thick enough?
Nice project! I would have rather seen hump instead of cut out for the bearing clearance thou, maybe next time😊
With a Hump I could not spin the compound full 360° anymore :-|
Curious, could you use the rear of the cross slide to add a solid tool post, or would you need to replace the compound on the front? Nice fit!👏
Forreal I thought l o spent more time looking at the bands on the back of his shirts. We need you. Everyone that needs a guitar bridge or a tuner or an eighty inch b20 gong. ::🤤hint hint::
Great idea for the chip cover. I’ve never been able to get one of those deburring tools to work for me either. Do you think the smell of the Anchor Lube might have come from the goat cheese that I sent you? Hahaha. Do you eat that type of cheese? I know it’s not for everyone’s tastes. Thanks for the video!
Dear Stefan, I completely understand what you're doing in this video, it's professional, but wouldn't it have been more economical to cut the sheet with a laser? At least here in Hungary, this is not too expensive, especially when compared with the time spent on it.
Again I got your passion.
Yes - On the Emco I sent the drawings out for lasercutting/bending and got perfectly fitting parts back, I think it was about 100eur for one.
But in this case, I treated it as a hobby project :)
Great result as usual. Is there a reason you used mild steel over aluminium ? galvanic corrosion ?
I find steel more forgiving, it doesnt ding up as easy.
Well i always do wonder if one could 3d print a cover but i did see that the mechanism is quite complicated.
I am sure, one could come up with a nice 3d printed design - Hot chips have to be taken into consideration, they would melt themself into a lot of the plastics used in fdm printing.
@@StefanGotteswinter That for sure i dunno if there are one way printable materials that are more resistent to heat..
And well i’d combine it with flood cooling so less hot pice’s of metal
Do the shields rattle or resonate?
No
lightly hand scrape the surface of the sheet metal or do a swirl pattern. it would look better than sanding it.
I prefer the chaotic sanded finish, it hides a lot of wear over time.
Does the thing that Stefan put in the spindle just clean the internal surface? I presume it cant have been a stoning type thing where it would knock off issues but be a tiny bit abrasive? Is it just a felty type cleaning thing to get crap out?
Thats just a spindle wiper with felt pads on it.
In the US they sell these and call them spindlemate. Boeing started using them and reduced their broken tangs on drills and chucks by almost 100%. Most people don’t know that tapers should always be dry not oiled. I use them on my tail stock taper.
