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.

[@sjhanson1690]

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…

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

[@tabbott429]

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.

[@SoGoodRc1]

Oh beryllium copper castings. I've done thousands brother weld gun castings are nasty parts nobody told about.

[@AB-80X]

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.

[@dougankrum3328]

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".

[@capthowdy126]

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.

[@mikehunt3222]

There are tons of machining channels out there. Check out Abom79, Steve Summers is a good one, and mrpete222 is also a good one. They all work with older manual machines especially Steve Summers and mrpete222 who was an actual shop teacher and has a small Atlas Craftsman lathe like I have and I have learned alot from him. There are lots more channels that will pop up in your recommendations browser once you start watching those channels.

[@floorpizza8074]

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.

[@bobroberts2371]

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.

[@novadoug]

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

[@35RSkyline]

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!

[@timcampbell5141]

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.

[@gregdriskell1290]

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

[@WilliamPayneNZ]

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.

[@makadafaka]

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

[@Jet2416-Reloading]

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.

[@SquarebodyStuff]

[@brookwoodmotoco5537]

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

[@mikehunt3222]

Hell, in the 20’s they never even torqued heads down. They just tightened them until they thought they were tight enough. The torque wrench never came out until the early 30’s. But if you can find an original block from that era that’s never been touched I bet it’s at least 1 to 2 thousands difference or even more. And any kids reading this when we say 20’s we mean 1920’s not 2020’s.

[@oldleatherhandsfriends4053]

@@mikehunt3222 The torque wrench was invented in 1918 so I'm positive it was used, most mechanics just probably didn't have one back then because they were expensive.

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?

[@DjMatt97]

the pressure between the cylinders is equal, so it balances the outwards force out on one another

[@AlexTRD1]

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

[@Midnight_Rider96]

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.

[@ryurc3033]

[@austinmusolff7852]

Ten thousands is .01 he meant tenths like 2 tenths is .0002

[@grantreid8583]

[@JMB676]

I find it interesting how it only needs to touch one side of the bore twice and when it goes to the other three sides it only touches once cause it already knows where the bores wall is from the first wall. This machine is impressive

[@PiDsPagePrototypes]

"Junk Block" - sounds like a research opportunity, to find the limits of how far down the factory piece can be cut, and from there, the shortest stroke high revving motor that could be made out of it.

[@gerrys123]

Interested newbie here. To machine the whole block you would first machine square the front and back of the block. Then bore the crank and cam tunnel square to the front and back, then do the decks square to that. Phew :)

[@PhilG999]

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"! 😆

[@rexschimmer7394]

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

[@obamapox8185]

Exactly what I thought but if it makes you happy that's ok ..but an encoder is not off by half a degree..it is what it says it is

[@LesNewell]

All machines have backlash, even if they use preloaded ball screws. It's just the amount that varies. What struck me is that the backlash move is in different directions for the left and right banks. This actually exaggerates the effect of backlash. To truly remove the backlash your last positioning moves should always be in the same direction.

[@rexschimmer7394]

@@LesNewell Les, I designed CNC machine tools for 20 years and they did not have back lash, there might be some sort of structural deflection if not properly designed. Everything we did had preloaded drive systems, mainly large ball screws, even rack and pinion drives on very large machines, we had special electronic combined with either split zero back lash gearing or double pinion drives. The preload was set above any load that could be applied by a cutting tool or the frictional load of moving the machine. The ball screws were also put in tension to eliminate any deflection due to any load applied to them.

[@LesNewell]

@@rexschimmer7394 Unless you can come up with an infinitely stiff material you will have backlash. When you reverse direction the screws stretch slightly and even the castings move a small amount. Preloading etc reduce it but it's always there. Good mechanical design and software backlash compensation will reduce it to the point where it has no measurable effect on the finished parts. I've also had 20+ years experience though admittedly most of mine is more in the control side rather than the mechanical side.

[@logannewman4532]

The dip in the middle of the cut is because of a TINY error in the perpendicularity of the Z axis to the X axis. But for a cutter that large to only scallop the cut by .0002 is impressive.

[@KPSchleyer]

It's done intentionally so it doesn't back cut

[@TheZFreeman]

I'm onboard with all of this except the backlash deal. If you have backlash in the rotary, you need to stop motion in the same direction on both sides. The way this machine is doing it is going to INDUCE any existing backlash that is potentially present, because it is stopping motion in opposing directions from one another. That's literally how you find the backlash, not how you prevent it from being a factor.
