How crazy things have advanced. I remember my first block that I had machined, and watched the machinist dance around it with calipers and straight edges, scribbling on a piece of brown paper, and rubber malleting the machine into position. That thing is amazing.

The wealth of knowledge this channel puts out is amazing, this is candy for my analytical brain. Thanks a bunch Steve and crew. I love this behind the scenes stuff.

I’m a retired Auto Machinist from several years ago, and it’s so nice to see how some of the machines have advanced in ways I always thought they should. Good job Rottler and Sunnen and Peterson etc…

Nothing beats working with a company that has a dedicated and professional journeyman millwright. The training and handover is everything. Ace!:)

This channel is super underrated. The attention to the little details and the super in depth explanations are awesome. Bravo 👏

If anybody would ever complain about that amount of concave depth, they would have flunked math. It’s 0,005 of a millimetre. The block will bend twist and move more than that under high loads. Heck, the gasket will be less accurate than that lol. Great job.

Interesting to see the specialty fixtures for engine blocks. I used to run 4 axis CNC mills machining weld gun castings and various parts for the robot welders. I learned so much and even learned a CNC router which we used to make the patterns for the castings. I would draw the part in 3D from a blueprint and apply toolpath software to generate machine code to literally carve the pattern in 2 halves from a block of bondo like material. So glad i did that when i was young in the 90s working 55 hours a week. CNCs are amazing machines. I was night shift foreman and we'd occasionally have time to make our own stuff too.

Man oh man Steve... This is "Absolutely Amazing!" Just how close these tolerances, measurements, logistics are in an engine build can & have become! I recall how getting a 3 angle valve job was considered the "cats meow!" Dern I have been around... Thank You, J

Awesome channel for learning details. Back in the 1970's and early 80's, I worked on building new machinery like this (Burgmaster), no CNC yet, just punched tape, although they were capable of 4-5 Axis movements, and could hold .0005". The machines aren't a whole lot different now, just much tighter and faster, but the Computer Software has really done some magic. Back then, you had to 'dial' everything in using....well, 'Dial Indicators'...good ones could read .0001".

I can really relate to the joy of seeing a machine like that...What a piece of art...🙏

Man that's a beautiful setup. Big investment but for sure will pay for itself in no time. And the technician seems awesome and super knowledgeable as well.

Very nice Steve. Congratulations on getting your New Rottler CNC. Getting it set up and operational and training is awesome. Thanks for sharing. Take care, Ed.

This is an amazing piece of equipment Steve. So glad you are sharing this new equipment with us. It’s truly amazing at how much it can do. Can’t wait to see more on this masterpiece and the hone!!!

i love watching stuff like this, this old tony channel is one of the best channels for learning about machining but theres just not enough content like this out there. id love to see someone who went through an done a tutorial on how to use a machine like this or even a non cnc mill. starting with the cheaper machines an how what u learn on the smaller machines can translate to the bigger ones. i just got lathe a couple months ago. 7x14 so really small compared to what u would see in a shop like that an ive almost got enough saved to buy a bench top mill but its all to be used to learn from. i own 12 3d printers, 10 fdm 2 resin and have a small cnc router an laser engraver so thats what got me started messing with this kinda stuff but in the past yr ive really wanted to use metals in with some of the stuff i mess with an 90% of the time i cant just buy what i need so the lathe alone has made life so much easier dealing with fixing hardware for my projects but going from the 3d printing stuff to the lathe or a mill is alot different but b4 its over i'll have it figured out even if it never makes me a dime i just want to learn an be able to use them for my own personal use.

Incredible piece of machinery. I have no experience with this sort of work, but the way you explain it is easy to digest. Thanks!

I love how happy you are, it reminds me of my days in the shop late 80s early 90s when we finally got the Sunnen CK10 we all were giddy.

I love what you're showing, I used to work for lukovich racing and Mike Moran and brought those techniques back to Hawaii, but on old equipment, such as a storm Vulcan surfacer, ck 10 hone, so everything was more manual, my hands never left the machine's

I'm amazed how fast this machine is. Love this channel. Thanks for your time Steve.

Great content thanks for sharing. Good luck with the new equipment

Thing is AWESOME.. LOVE that lighting, they did a kick a** job in that!!

Going thru medical down time...enjoy your vids and top it off just to see Dewey strolling through makes me forget about pain for awhile😃

Listening to this video while doing plugs and oil on my 5.4 3v ha.. makes me want something cool to build

That puppy sure does a good job making sure y'all don't mess stuff up. Steve and Kevin Smith love their toys.

Wow, impressive mate. On your way to the top, thanks for taking us along.

Ya it’s PERFECT beautiful finish also!!! .200” is a HAWGGGGG CUT!! HAWGGING OUT THE METAL!! Always nice having a brand new machine without backlash, crashes and new software to do cool new stuff!

Steve just amazing I'm no machinist but my father ran a tool and die department .Wish he was still alive to see how things have advanced in the last 35 years he was such a perfectionist he would of loved watching your video's . Thanks for sharing

This is awesome. Thanks for sharing with us.

That is so bad ass! Pardon my language... The accuracy and speed is incredible. Not to mention the power! A .250 cut..wow! Thanks for sharing..

I'm totally impressed!!! Thank you for sharing.

Would love to see the line bore operation and learn more. Absolutely love these kind of videos. Great job

At 55 years old, I can't wait to grow up and have an engine built by Steve and crew. Only ten more years til that happens (retirement). Very cool video, Steve, thank you. That is one hell of a machine.

Would love to see a 30’s 40’s whatever era block measured to see how out of spec it is compared to modern blocks

Excellent information, glad I found your channel!

I remember one of your videos where you were enquiring about this machine with a younger sales rep at some show. Thats pretty good turn over having it running in your shop

I’m so glad I found you from Cleetus, just a wealth of knowledge.

This was very good. Thank you Steve and company. :)

My new favorite channel. Love watching this kind of stuff. Especially when seeing to what end all the hard work goes to. 💪🏻💪🏻

Sweet machine. I guess you can put the bores where you want to compensate for thinner thicknesses between cylinders (thinking RB stuff). Be cool to have a little vacuum to collect all the debris from boring too.

Man I love Steve's enthusiasm.

Muscle Machining in Largo Florida has one of these. It's a marvel to see in person.

It's so cool to see how the newest technology works so well! We have all kinds of cool machines where I work. We have robot welders, two flat lasers a plasma table and I run a tube laser. We also have some pretty cool cnc machines. Two mills and a cnc lathe.

Very cool. I work in a highly automated field and to see what some machines are capable of is incredible. Some wicked smart engineers out there.

Dog looking like Scooby Doo with that teal collar. Lol

The best advertising Rottler could get on this machine is on your purchase and subsequent videos. I know they'll treat you well for that. This type of high tech is way out of my league, but you explained everything so well that anyone could fully understand everything you described. Such a cool machine. How many tee shirts do I have to buy to pay for your machine? I'm guessing "all" 😁

Fantasttic to be able to see this and learn . Thank you Steve for these pricelss videos.

Couldn’t have timed this upload more perfect. Just when I got on KZfaq. Can’t wait to watch it

What a Beautiful Machine! Mr. Morris, would a torque plate mounted on the deck be of added benefit when Blueprinting the Cylinder Bores?

Really appreciate you Steve. Thanks for sharing all your knowledge for us likeminded gear heads who want to absorb everything engine related lol Also question..how is the space between the cylinders so thin compared to how thick the outside walls are, yet they don't break there?

That is a sweet machine don’t let the keyboard machinist get you going they probably can’t read a tenths indicator anyway great work as usual

You can stagger heights of the fly cutter bits and move the lower bit inward on the radius to do a rough/fine cut in a single pass

Nice machine, never got to run it but I worked in a shop that had a bigger rottler machine to do big diesels flat on the table and a 4th axis just like this one

That is a really nice machine. It should save a lot of time and refine all your block machine work once all the machinists get accustomed to its operations. It looks like that "junk" block has been dry decked. It's the first dry decked LS block I have ever seen. Whoever did the work did a nice job. I'd love to see SME dry deck a block you intend to build.

The other reason for an engine rotation overshoot is so the servo ( and brake ) is holding the block up rather than keeping it from falling down. RE The block wants to continue to flop over and close up the backlash but if we go past then to level, the backlash if taken up.

That's very flat. That is the type of flatness we hold where I work. Very nice! I run a makino A92 soon to be switching to a new A120 coming in! Running the transmission case for the M1A1. Lots of adjustments and tool changes needed to keep the finish good and to keep flatness. Fun stuff!

Thank you for posting all the great videos on your channel

great video Steve as usual , its fascinatng watching the latest in technology be applied to your craft , keep the content coming my friend !

Mr Steve, I tell people that machine setup is the time consuming part. 😉 And now you're at NASA level in the world of machines. 😁😃😃😃😃

The machinists inside my stress out seeing that fly cutter in operation with no one wearing safety glass 😬. But I love this machine

You could run a spring pass at Z0 just have to watch for vibration or SF being off. Should fix any flatness issues. .0002 isn’t much but looked like .0003-.0004 to me lol

Cool video, I could watch machinery videos all day, thanks for sharing

Do you have to account for heat like expansion caused by cutting??? When measuring cutting the bore cause no cutting fluid

Maybe I missed the part of the video or another video, Why are you machining dry? No coolant flowing through the process to move chips and cool the tool and surface.

I love your videos. You are not afraid to educate. That's very cool.

I wish I had "Junk" blocks like that laying around. Cool video!

I'll come and sweep the swarf up if you train me on stuff. Seriously, thank you for taking the time to show us how things are done and why. I'd also like to see how long it takes to set the block up. Having just paid for a block to be machined I'm sure there's more cost than just drilling the holes.

That's a badass machine! Should be an excellent addition to the shop!

This machine is absolutely fantastic its great to watch and your excellent experience with the speaking on the machineing is great

That’s one bad ass machine. You’ll be using it to do my motor as soon as I get the cash.💰🙏🏽

Thanks for sharing buddy such a awesome machine

Love this stuff. Sweet unit there Steve.

Love video info thanks Steve. Watch for Dewey eyes while the machine is firing aluminum chips at 1050 rpm. I remove from shop when welding or grinding, love em but not too smart 👀👀they always got one eye watching aka shadow.

Very cool and informative. BTW just received my new tee shirt, love it!

Soo cool. Man id love to spend a day at steves shop.

AWESOME machine!! I love how Dewy over sees everything!!

As a fellow machinist of sorts, when Steve said tenth, I'm going to assume he meant the short hand slang for ten thousandths. Its just an easier way to say when you basically only deal in thousandths and ten thousandths.

I would have thought that it would need some kind of coolant for cutting.

Its pretty damn cool that the tool is held in place via suction

man it doesnt get much better than that...its just simple the best machine on the market..congs on the purchase..thanks for sharing with us..

Very freaking cool… what a beautiful piece of equipment… just love video… 👍🏻😎

15:17 Looks shiny! Perfection!

Nice. Now you know how thick the bored is to the water jacket . It's amazing I'm automotive machinist old from 1972 . Lots of boreding and honing ck10. Back in the day in Australia it was un herd of to have this type of machineing. Thanks Steve for your insight to moden engineering.

Love this video as usual I’ve learned a lot,,,nice machine…😊thanks.

That's a cool machine, that's for sure. Nice upgrade, and very accurate.

That is an amazing piece of high tech gear, the only thing you missed demo'ing was the coffee-making option.

Hi Steve Forget about measuring things with a Dial Indicator. View it as a comparator. Ooh I forgot. The .0001 u r seeing may be distortion in the block thanks to the holding device u r using.

Cool to see technology making things easier and better. And your junk block is probably better than anything I've ever laid my hands on. Lol.

What an awesome new addition Steve.

You should see the CNC machines at Cummins. I'm an industrial electrician contracted in there. It's getting pretty insane. A lot of robots.

Love these machines! Might remind people that when machinists/Engineers talk in "Tenths" we mean "Ten thousandths" of an inch. Some might not know and think a Tenth" of an inch means 0.10" when it's really 0.00010" 😁 Oops. I spoke too soon. My bad for typing before you explained it @12.08! 😔 And seeing that "junk block" painted black reminds me of the time I was building a SBC 350 for my '76 V8 Monza, and a friend asked why I painted it black? "Won't that make oil leaks hard to see?" I said: "Engines *I* build don't leak oil"! 😆

I love CNC machining equipment. Very nice!!

If someone is facing something on their milling machine and they are getting scallops in their surface or they are dragging the cutter after a cut that means that the head of their machine is not perfectly 90° to their machine table in X and Y. It does not matter what angle the fly cutter or fly cutter tip is on it will still cut flat if the head is 90° to the table the only thing that would change is the diameter of the cut. If it is scalloping or dragging the tip it means the head is out. Think of it like a Bridgeport milling machine when you angle the head it obviously won’t cut flat on an angle. Same with facing anything if it’s not trammed in properly it won’t be flat. I hope that makes sense.

Other than a huge congratulations on that new machine, I have one question after machining the surfaces of the block. On each side of the head bolt locations there's an irregular trianglish shape that is a different color, it's a lighter colored "splotch" Those would look to be water jackets, but they don't have any depth, so why are those a different color? Looking through the comments I saw someone else asked this question. I'll repeat my question that I made on the other fellows comment. You said those were pressed in, not filled openings in the water jacket. With such an irregular shape, what do you use to press in and fill those openings. Do you have to machine the block to fit a fancy shaped water jacket plug? I can't imagine a casting being accurate or smooth enough to press in a plug. This machine is going to totally change your shop, I can tell that already. 👍👍👍x

Really cool stuff. Seeing all the machines and the knowledge it takes to run them before you even start thinking about making HP makes it seem like you’re giving these engines away. I don’t know what’s funnier, people in their mom’s basement that think they know better or Steve reading their comments and addressing them 😂

Steve, when boring or decking or really any cutting, should you not be adding liquid cooling to ensure you don't get temperature size changes on the tools? Or is there more of a risk that fluid will trap debris on the tool that could add extra size on the precision cuts?

Thank you for putting this content out here you are the man lol I love watching a few hours of your channel at a time and just learning and absorbing all the info keep the amazing content flowing (came over during the cleetus build) and I am happy I did

As a ex-machine op I really appreciate the clear vision of the work. Ours was all cloudy and cracked from previous crashes and milky from the coolent.

Great machine and instructive video, thanks! No lube/cutting fluid used...?

Steve, Pretty neat machine. You mentioned "back lash" a couple of times regarding the "A" axis rotary movement. You are showing your age, all of us old guys do this type of move because most of us have operated machines with bronze drive screws which wear and have backlash. Machine tools like your new one do not have any mechanical back lash, all of the axis are driven by mechanisms , ball screws, that completely eliminate any mechanical backlash and are preloaded to eliminate any possible drive deflection due to cutter load. Part of the machines great accuracy is the actual structural stiffness of the machine structure and your new machine certainly appears to be very stiff. Very cool, thanks for showing us. Rex Schimmer

That's bad ass man, congrats!

Awesome machine takes the human error out of machining, wild machine, all the best to yous and your loved ones
