[@michaelpatrick6950]

As a young process engineer in a corn syrup manufacturing facility in the 1970s, we were expanding our plants at warp speed and often did temporary piping as new processes were installed. I gained the nickname Mr Goodwrench because I was always taking stuff apart and putting it back together. The old guy pipefitters taught me to always use thread lubricant because our areas were wet and carbon steel bolts would rust quickly. Also we had to use it so stainless bolts wouldn't gall. If I had the value of all the clothes I ruined with nickel based anti-seize and CopperGraph we used on gaskets, I could have retired a couple of years earlier.

[@ajosepi1976]

That feeling when you have always only had used stuff and finally get a new one is really something. You may have bigger and maybe better machines, even new ones, but this will always have a special spot for the rest of your life. Even if you end up hating it, you will still love it.

[@yafois988]

I've leveled robotic machines for decades like this, its a skill set and very critical for several reasons such as having a tool operate properly consistently reliably, and a finished product that depends on leveling accuracy! Few ppl really realize how important this really is.

[@bcbloc02]

I have never run a lathe that wasn't already WELL broken in before I used it. You are a lucky man!

[@WreckDiver99]

I remember my summer as a machine builder (college kid, first 'responsible' job in an industrial setting (building drive shafts for DANA doesn't count here)). We had huge bases for a big machining line that was being built. 16'~20' long, 4' ~ 6' wide. Each base had 8 to 12 leveling screws (2-1/2" screws). It came time to finally level those things (30 or 40 of them), and they brought out the laser instead of the levels. I chased that damn beep an entire day trying to get that think level. It ended up taking a solid week to get all of them done and I only did one of them, the "experienced" guys took over and it STILL took them 1/2 day per base working in teams. Still one of the best "college" jobs I ever had. I got introduced to the Bridgeport, surface grinder, lathe, drill sharpening, indicating, surface plate work (basic), and a few other things. I loved it, and looking back at my life 30+ years later? Probably should have stuck with it...it was enjoyable.

[@francisschweitzer8431]

Sounds like major deal even with lasers…. Can you imagine if all you had were bubble levels

[@WreckDiver99]

@@francisschweitzer8431 I can't...just can't. It was brutal with the lasers because they were so sensitive and beeped like crazy. You'd move ONE screw just a fraction of a degree and BEEEP....move to the next corner...BEEP...move back "nothing". Also due to the size of the bases you had flex in the middle of the base, so you were adjusting constantly. What really should have been done is use a couple of sensors, find the low spot, high spot, and move from there. I think they finally did that near the end, kind of how you would do grade stakes for building and such.

[@wadenixon9455]

I bought a Precision Matthews about 10 years ago. Have had great results 👍

[@bridgetstoli2347]

.002" may as well be level as far as coolant is concerned. Our machines were lined up with the rest of the world and they drained just fine.

[@waynepollard6879]

Whoever did that floor , deserves favour ! That machine is beautiful ! Happy lathing Adam .

[@MFStuffNinja]

Years ago a work acquaintance gave me a piece of gymnastics foam to save my knees at work and it lasted me for years. It was durable and washable, and didn't break down like foam rubber pads do. It only needed replaced because I got roofing tar on it, and it took me a while to track down what type it was. As it turns out, toolbox makers sell it with a fancy name -- "Kaizen foam".

[@kaine2416]

I have a cheap rolled up yoga mat that has saved my knees over the years. Took me about 2 years of regularly using it to wear it out and it only cost me $5 to replace. Even saved my back a few times rolling it out to work underneath my friend's car in gravel. 100% worth it!

[@ItsMrAssholeToYou]

Useful info. Thanks.

[@stevecourtney8572]

They make a expoy you can run around your leveling pads to hold them in place. You just pout it around them and let it dry. We used it to set Cincinnati machines years ago

[@richardfrisbie6069]

I honestly can't believe the amount of people that are so concerned about pitching the lathe downhill towards the tailstock for coolant drainage, when what is required are the ways running on the same plane. The lathe could probably run in an almost vertical position and machine accurate parts, as long as the bed is in on the same plane from side to side, and no I'm not talking about being parallel, the structure takes care of that (just wanted to confirm, some of you probably don't understand what the webs in the casting are for either). If the chip tray slope bothers you that much, look the machine up and see if it specs the chip tray slope maybe that will keep you occupied for a while.

[@Galerak1]

Wouldn't the drainage of the chip tray be built in at the design level? What I mean is, if they suggest using the top of the cross slide to level the machine then maybe the chip tray is already built with the desired drainage angle if the machine is levelled correctly at the cross slide. I'd have thought that if they are making a precision machine to create precision parts then they wouldn't expect an end user to apply guesswork to add drainage angles for coolant. Just a thought 😉

[@johansamzelius2503]

Just what I thought too 😏

[@elischultes6587]

I was hoping so

[@robertbutler8004]

Galerak agreed it would be like a bathtub you set the bathtub into the wall and have both the length and the width level and the tub would be manufactured to drain to the plug and this lathe would be the same.

Good evening from central Florida! Hope everyone has a great night!

[@deejayqueue]

I really enjoyed the first few minutes of the video, watching the pads get faced and chamfered. Just hearing the machine running was neat, like ASMR (Abom Swift Metal Removal).

[@ophirb25]

First congratulations and good luck with it. Second I believe that a smart manufacturer will set the chip tray so that it will be at the correct angle to drain the coolant away from the head stock without the user needing to tilt it at 5he time of leveling. Not sure if that is the case with this lathe, just my thought on the matter.

[@bruceanderson9461]

Wants the ways to drain. Not just the chip pan

Great information about how to level the lathe. That machine looks well made. I hope it is a good powerful and accurate machine because I like seeing you make some big cuts sometimes lol. Enjoyed the episode and the information. Keep em coming.

[@millomweb]

He's got other lathes to hammer with big cuts - he should use this lathe as little as possible to preserve its accuracy. As someone said in a previous episode - he should fit an hour meter to the motor wiring to record how much the machine is used - to plan a maintenance schedule. Had the bed not been somewhat prelubed, he'll have put a year's worth of wear on the bed already. He's talking of cleaning all the protective gunge off it. I'd have squirted oil all over it first.

[@sheemondallasgeorgia]

Me thinks leveling is not important. Lathes are used on boats of all kinds. What is important is to take out the tweak, the twist, the lack of symmetry. A simple way to achieve this is via leveling. Yes, there are jobs where one want to use a level for initial holding of the part. But this is just an opinion, and those I have plenty of. I like this new wave of episodes. You seem to having recovered your aim. Great!

[@floridaflywheelersantiquee7578]

It’s exciting to see a new machine

[@nkelly.9]

More great content Adam. I am well familiar, as I am sure you are, and many viewers are, with backlash in older machines. Could you show us just how much backlash there is in your wonderful new machine in its "as new" condition in a video some time? I think it would be fascinating to see/compare , especially with your older machines, just how much backlash there is. We are all spoiled with DRO units. The old guys had to deal with backlash and dials to hit the numbers. Hats off to them. It would also be great to see you align head and tail stocks, do some test cuts on the new machine, your professional and methodical approach would make it fascinating.

Does the chip pan not already slope down (designed and built that way) toward the drain side so you don't have to make the whole machine un-level?

Perfect timing Adam! I just got a 12 x 36 PM lathe. This tutorial ids just what the doctor ordered. Thanks!

[@millomweb]

Oh dear ! Please follow the instructions in the manual !

[@32thedoctor]

Adam, those far left feet that you just snugged up actually can affect the tilt of the headstock independent of the ways. You want to make sure that the spindle's axis of rotation is parallel to the ways and those adjusters will affect that. Joe Pieczynsky talks about this in one of his lathe adjustment videos. It was a pretty good explanation as I recall. I'm told that some lathes actually have an adjustment on the headstock itself, but I've never seen one. That lathe looks really sweet, BTW. Congratulations on the new and shiny machine!! I'm retired and just have a small shop in my basement. Got one of the smaller Precision Matthews machines and I've had good luck with it. The company has great customer service. I think you'll be happy.

[@francisschweitzer8431]

WOW… interesting point. How would a person go about doing that level?? I’m thinking it’s a tool like a bore sight laser inside the spindle. Am I close?

[@OmeMachining]

I know some Colchester lathes have a pivot point that you can adjust the headstock 'on'. That way you can make it turn super accurate. Depending on the lathe size and how it's build, it can be hard to adjust/twist it 100% without bolting it to the floor. Some are super stiff and won't twist, only raise/not touch as hard on one/another feet 😊 Best regards

[@richardfrisbie6069]

Adam has done this long enough that I'm sure he knows all about it. It's actually a separate procedure that either takes a precision bar with a taper to fit the headstock, or the use of a 4 jaw chuck, which wasn't available at the time the lathe was shipped.

[@vendter]

My Hardinge CHNC has adjustments to align the headstock to the lathe body.

[@32thedoctor]

@@francisschweitzer8431 I think laser would be the way to go, as gravity is not your friend here. I came up with a method that I used to compensate for sag of a chucked precision ground bar (can't use tail stock for this adjustment for obvious reasons), but it's too involved to explain here. Basically it measures the sag of a chucked test bar and that value is used in the adjustment. I'm working on a small hobby lathe 12x28, but the theory would apply to any sized machine. I leveled my machine about once a month for the first year I owned it. It took that amount of time to settle in and stabilize. I think it's because it's so light. The last few times I've checked it, however, it hasn't budged and I'm getting some great precision on this little chineseium thingy. I'm jealous of Adam - I don't have the room for anything bigger. But you know what they say. It ain't the size of your tools that counts. Wait, what?

[@garbo8962]

Thanks Adam, my PM-1440GT just arrived today! I made my leveling pads out of aluminum.

Aluminum has been just fine on my 4000 pound Monarch, they should be okay on this 1500 pound lathe. I shouldn’t have to worry about corrosion either.

[@JohnRoberts71]

Why isn’t a pitch or slope built in to the catch pan?

[@vendter]

I would check the chip pan to make sure the factory didn't already put a grade in it.

[@cornpop7805]

That's not why he's leveling it at a tilt. It's so fluid doesn't travel along the part being machined and going through the chuck and running on the floor.

[@vendter]

@@cornpop7805 It takes about 1% slope to get water to flow. That would be .12" per foot. He leveled it at .0005" per foot. I can't see using the lathe accurately with enough slope to make sure the coolant did not flow through the chuck.

[@cornpop7805]

@@vendter That's the rational he used. It's based on a flawed understanding of "tilting the headstock", being for coolant drainage. The real idea of tilting the headstock is something that machine tool builders do to help counteract tool forces. If you're interested in exactly how that works, I can copy and past a somewhat detailed explanation that I wrote another person in the comments section.

Six years ago I wanted to drill a hole in hardened steel and no friend had time to do it immediately , normal I let them do my metal work cause I thought I'm not good at it. So I tried, but it didn't work 😭 I picked up my phone and looked at KZbin for an explanation....this must have been the moment the metal virus got me...what I always thought that it's a boring thing was a whole new world for me ( at age 44 ) it was very interesting and mind blowing...two weeks later my first brand new lathe came 😂 and another week later my first mill 😂 which were replaced after a year to bigger ones ( lathe 350kg mill about the same) and despite being a hobbyist ( studied law ) I have a hobby workshop for about 60K all bought the last years🤪🤪🤪 and divided into two rooms to keep the grinding dust away from the other machines and tools 😇 and its the responsibility of guys like Adam why the metal work theme was so fascinating that i spend every free minute in the workshop . Also I was becoming the star for my friends and neighbors because if they need a repair I'm glad to do it immediately for them never taking a cent even not for the material.😁😁 I know but I do it with such pleasure I don't want to take money for it and the number of people who come to me is increasing ever since 🤣🤣🤣 When I don't repair things I have two houses which there's always metal work to do or just copy nice projects from KZbin.Since I converted my mill with four Nema34 12.5Nm Motors to CNC the fourth axis a turning axis i made myself out if steele and in near future I make the 5th also the possibilities have increased cause I can't mill the complex forms the computer can do but by using the wireless Handwheel I can use it like normal only with more precision...🤪 So thank you Adam you cost me a bunch of bucks but gave me the best hobby I can think of 😁😂😂

[@camillosteuss]

I discovered machinery of this sort around 15 years ago, and since then studied it from manuals and books and online from joe, stefan, adam, robin and so on... Last year i got a Schaublin 22, Schaerer UN450, Emco FB2, a yugoslavian baby lathe, a Deckel S1 t&cg and a few other tidbits... An extensive list of tooling and measurement devices aswell... Now i am setting up my shop, and like you, plan on two rooms for grinders and the dust crew as none of that grime is ever gonna see my machines, but the feeling of running a 3 ton lathe, or a factory new Schau22 is just amazing... The baby machines are there for parts that would be an insult to the large machines, as you dont turn a 1 inch bushing on a 3 ton lathe... Nor do you drill a few tiny holes on a 1 ton mill when the emco will bust their ass with joy... Heck, the only reason i got the machines are guys like adam, tony and the rest... Seeing them work was such a pleasure i knew it could only be even better not just lustfully watching the work being done, and so it is... But fucking hell do you need a load of cash to get all the tools and precision devices after the initial cost of the machines... I think i have seen your ass on robrenzes channel wolfie, or was it suburban tools? likely the latter, and i am glad to see this comment from you, its a great joy seeing someone else discover the loveliness of machinery as such... They truly are a darlings to be loved, and as you said, they do make you much more liked, as peasants who scrounge for a screw and overpay junk run to you in heaps with pleading eyes as soon as the word gets out that there be a machine enthusiast with proper machines and if not official, good learned knowledge, gotten through much more interest in the subject than many who finished proper schooling have, as most in schools are there out of necessity, whereas we fell in love and spend every moment either watching or reading about the art of it, or now even engage in it :) All the best and warmest regards!

[@paulhunt598]

The next step to level an engine lathe is to confirm taper. A standard in the chuck can be indicated against from the saddle travel. Indicate along the top side of the standard to see the indicator easily. Adjust the rear headstock leveling bolts to correct error. You are adjusting for "up/down error" only at this point. Now reconfirm bedway twist, sagging and crowning employing the demonstrated methods. You will likely do some tail chasing closing in on machine level. Twist correction is vastly more important than level as Adam demonstrated by intentionally adding slope for coolant drainage. .002" slope is arguably insignificant for coolant drainage, but certainly causes no machining harm. The final step I would employ us to validate headstock taper. This is done by turning a sizable piece of stock with as much stickout that won't allow part deflection, No Tailstock Engagement. Test part finish is critical for best taper measurements. Mic the turned diameter. Adjust to correct taper by loosening the headstock hardware and adjusting via the adjustment screws at the rear of the headstock. The front of the headstock pivots on a pin centered under the chuck end of the headstock. Make certain you track headstock movement before loosening the headstock hardware and while making adjustments. Monitor adjustment with at least .0005" test indicator. A .0001" may max your indicator travel when you loosen the hardware or make adjustments. Tighten headstock, recut test piece and confirm taper correction improvement. This procedure can take several test cuts to eliminate spindle taper. Your first compensation correction success gives guidance on how much to move to obtain the desired and needed taper correction. I had various pilots that varied in their opinion on how much taper was acceptable and if the tailstock end or the chuck end should be larger if no taper was unachievable. The type of work performed on the machine will help dictate this decision. This is a toolroom lathe and I would expect that Adam wants precision work and he will machine with light tool load for finish management and tool deflection minimization. I would shoot for .0000" taper over 12". Even brand new machines need the taper confirmation. You could see from the video how much an engine lathe twists, crowns and sags. Shipping and rigging is not kind to maintaining factory adjustments. Ideal leveling methods would have included anchor bolts. Anchor bolts allow down pressure that machine weight cannot provide. Machine design mandates that anchor placement must be done before the machine is set in place. Aligning over anchors set in concrete is a challenge. Adam placed this machine by himself with a jib crane. He would have really frustrated himself lowering over preset anchor bolts. An alternative is to core drill the floor, remove the core and set J bolts loosely in the hold down holes. Place the machine with the J bolts dangling in the holes. Set grout to secure the J bolts. I only bothered with this step a few times, and I have set up hundreds of machines. The haters will point out that Adam straddled a floor control joint. This is unwise, but I managed machine tool set up for 34 years and found that we suffered virtually no machine tolerance issues in our parts coming off machines that straddled control joints. Adam already explained that he straddled the control joint to allow room for a knee mill under his jib hoist. Sometimes we have to make compromises. His machine is too close to the wall for OSHA and NEC required workspace, but he squeezed this dimension for the same space constraints. I demand best practices. But life forces compromises. I have some tricks that I would have pulled out if I did this job, but high precision is never perfect in reality. Adam admitted using 1-2-3 blocks is less than perfect for parallels to straddle the V way. I agree, but Adam reduced his error by confirming 2" dimensional accuracy. He had no provision to inspect squareness and flatness, but I agree that his technique with the blocks was pretty good. If you employ parallels to bridge the V way, consider using 2 precision levels, one on each end. Then you don't introduce error by moving parallels and levels. Old lathes didn't have reliable flat ground surfaces to set the level like Adam's new machine. This factory ground flat and parallel surface is very handy for lathe setup. The cross slide rides on the carriage on the flat and V ways. Since twist, crowning and sagging are your machining accuracy enemies, all can be inspected simultaneously. Hunt on chuck runout compensation... Old chuck OD's we're not trustworthy for indicating surfaces. OD was not always true to chuck centerline. This was regarded as a non critical surface and machining complexity allowed for machining tolerance. The chuck face was more reliable, but indicating here meant interrupted surface for the chuck jaw slots. Modern machining allows for the non critical chuck OD to be machined true to the spindle mounting surface and enables the chuck OD to be a reference surface. This manufacturing improvement enormously improved my life.

[@DavidHerscher]

This machine... I think i'm in love... I just can't get over it. This thing is SO DANG LOVELY.

[@samuel_towle]

I'm curious to know if it will maintain level after a few months of use. I'm thinking the vibration of the machine through the feet might be enough to wear the high spots down on the floor. Maybe check it again in 6 months or a year.

[@dennyray69123]

Did he grease those tiny ball feet on the end of bolt that goes into the floor pads. If not, vibration could change perfection very soon

[@elischultes6587]

Thought I had heard someone else say the cast iron relaxes too. Could have been my Grandad or it was on a Keith Fenner video. So a readjust might be necessary eventually. If the weight was adjusted properly it shouldn’t shift to much. Grandad said the lathes in many of the shops he was working in were on foundations drilled into bedrock.

[@bulletproofpepper2]

thanks for sharing! sweet! new lathe so far. i can almost smell it.

[@willclark491]

Don't you then have to turn a shaft and check for taper as a final test for bed twist?

[@millomweb]

He should unadjust all the gibs, thoroughly lubricate all the slides and other oil points, give himself a good workout, then adjust the gibs properly, then set the tailstock on centre, ensure the headstock is aligned with the bed vertically and horizontally - then he'll be ready for turning test samples.

[@robertvanderzaan9681]

Adam, you are talking about the runoff of the coolant and that is why you don't set the machine exactly level. But isn't runoff of the coolant not taken into account in the machine? I know absolutely nothing about lathes, but this made me wonder?

Hey Adam, I am no machinist, but I would think that a lathe manufacturer could easily make the coolant run to the sump with the lathe leveled in all directions. Great camera work.

[@alwayssaturday4607]

I’m not a machinist so help me understand why you go thru all the trouble of a precision level process and not make it level? So the flood coolant flows toward the tail stock. Also makes you wonder why the casting or maybe the flood coolant pan doesn’t have a tilt toward the tail stock built in. I welcome opinions from the machinists reading this. Thanks.

[@ebutuoyebutouy]

Agree w u. Manufacturer should take care of drainage.

[@boots7859]

More than likely there is already proper drainage and tilting should not be necessary especially considering the price. However maybe he's done some research and thats the prevailing wisdom. Also, the most important part was the second half where he is taking the twist out of the ways which will result in tapers and bad cuts. Quite possibly the first half was not really needed.

[@cornpop7805]

That's not why he's leveling it at a tilt. It's so fluid doesn't travel along the part being machined and going through the chuck and running on the floor.

[@t.d.mich.7064]

Nice lathe! I might have been tempted to paint or use Birchwood-Casey cold blue on the leveling pads. Interested on cutting a fairly long shaft for end to end diametrical accuracy.

[@ydonl]

Yeah, but... let's get it powered up, first. :)

[@PoulLausen]

YES! An Abom production again.

[@woodenhead8887]

Nice video Adam. Next step... put a piece of precision ground material in a collet at the head stock and adjust out the flex/nod with the 4 jack bolts under that end. Picture the axis of the spindle being level in the same plane as the ways. TOT has some good details on that.

[@patheron7812]

Yes, I too would like to see a video on headstock alignment.

[@andymaltby4518]

Hi Adam, Amazing job on the levelling and nice to see one go so smoothly. Best of luck with the grease removal an oil change etc; I'm looking forward to seeing the first accuracy tests!.

[@billcooley5527]

Are you sure the manufacturer didn't tilt the pan for water when the ways are level?

[@erichill5208]

As sensitive as your master level is. It seams to me just tightening the lock nuts on the leveling bolts. Will change the level. Very interesting proses I have never seen before 👍

[@TheMulk777]

Man, that's exciting! I bet it feels like forever waiting on the electrician. Hope to get a mill and lathe from PM someday...

[@williambrentnall2471]

awesome, I go by you 4 times a day thats me beeping the horn

[@EtherealProject3D]

What a beautiful machine, Ive had the PM 1640TL on my wish list for a couple of years. One day.

[@dwightbrown2808]

A while back you demonstrated a different sort of level. It was about 3" x 8" or so. (I think it was your channel, sorry if I screwed up!) It was sort of a flat box with one large circular vial that would allow leveling in both directions at once. I can't for the life of me I can't remember what it was called. Thanks!

In working with large sheet metal presses and rams the final check is across corners

[@patrickguarracino3174]

As a retired millwright we always used dial indicator on top of the foot when tightening down checking for a soft foot condition then shimming for zero pull down… then again it’s only a lathe

[@ebutuoyebutouy]

So true. U don't want to twist the machine.

[@bobbyp378]

Adam, fantastic job leveling in the Precision Matthews, I just finished un packing and leveling in a new LeBlond RKL-1340G and it it looks exactly the same as the PM just different paint job.! Any way, I found the easiest way to get that rust inhibitor wax off is copious amounts of mineral spirits, brass o-ring picks and a brass scraper, I made one out of a piece of 1x1/4 flat bar.

[@lucasandri5462]

Can't wait to see it running and making some chips as well as the pacemaker. Good interesting video as always.

[@MikeHarris1984]

Everything you machine looks amazing. Works of art!!

[@cocojojo1850]

THE MAN!!!!! your most definitely an inspiration.

[@jameshockey6916]

Exciting stuff, looks like a great edition to the new shop

[@cornpop7805]

I have built (at the factory) and installed many lathes, we actually made ours level unless the customer wanted it pitched. If the coolant sprays towards the headstock, liquid will go through the spindle bore, regardless how the machine is pitched. You just plug the spindle bore or stuff a rag around the stock, if you're running material through the spindle bore if you don't want drips. This whole pitching the machine thing is 100% BS. However, what machine tool builders do when they build a machine is, everso slightly tilt the headstock down and toward the operator (2/10,000"/6"). This is not the whole machine, rather the center bore of the spindle is tilted down in comparison to the bed. This is because single point turning (contact being on the operator side) will deflect the material up and away from the operator. So if the spindle was perfectly centered, a part (even with the finest finish cut) would be slightly bugle shaped (smaller at the headstock side). So, slightly tilting the headstock down and towards the operator, will counteract these forces, to some degree and attempt to eliminate the bugle shape on low force finish cuts. ALL serious machine tool manufacturers build this in at the factory. It is then the installer's job to insure the machine is installed in this same condition. I believe the myth of tilting the machine so the coolant will flow correctly, comes from people misunderstanding what tilting does and where it's done. Also, "tilting" is not supposed to be accomplished with levels, you do it with the test cut and 1/10th mics. Trust what I have said, I am 100% certain this is correct.

[@RobertPerrigoOkiechopper]

I love this channel , you're living the life I can only dream of.

[@wetherabble8031]

Lastly... Adam, weight loss journey, still a thing. I haven't watched your videos for a while, but keep it up! I've lost 100lbs in 12 months just trying. I bet those are rookie numbers for you, but keep up your good work in that regard as well.

[@juliejones8785]

Hi Adam. You mentioned that you just snug the head stock end adjusters. It seems like you would have to adjust them so that the spindle is parallel to the ways. I would imagine that this depends on the rigidity of the casting. I imagine that you do something similar if you have feet/levelers under the middle of the bed like your other lathe.

[@JJJohnson-e7h]

I just asked this very same question. I was curious about that as well.

[@zednott]

they sell those knee foam boards in most big box stores in the garden dept.

[@lwnf360]

03:04 --getting it all over your hands IS the correct way to use anti-sieze. I've never been able to not have that happen. 😆

[@RevenantMike]

Hands, shirt, face...the dog. Everything is fair game for anti-sieze.

[@Newberntrains]

The ceiling is never spared with me

[@ydonl]

I think that's what he said. :)

[@donaldhollingsworth3875]

I would recommend using leveling pads to level the machine then set the leveling pads & bolts in quick set concrete made for machine tools. I would have poured a separate foundation for the machine with mounting anchors. Also I would have hire machine tool riggers to level the machine. It would have more than worth the cost. They have the lasers needed to level the machine.

[@noahstephens7622]

How would that have been worth it when he got it basically perfect himself? Doesn’t really matter what you would have done honestly. It’s wild that the first thing people do is watch a 30 minute video of a professional with a couple dozen years of experience and immediately criticize and say you could have/would had done it better. Let’s see your video then bud.

[@jemijona]

If you are floating in money, that's fine. But hobbyists aren't always swimming in cash and aren't doing top precision turning, so doing it like Adam can be all that is needed. I'll be doing mine myself. I'm not making precision tooling.

[@ydonl]

That was fun! Thanks for showing it! Glad it went well. Seems like your measurements are even more precise than all the little gotcha's that will creep in over time!

[@tomasjosefvela1]

"I know that would be the proper way to use this but..." hahahahahahaha!!! I could not have related to you on that more! I work on cars and use that stuff often and I'm here to say it's a love hate relationship. I swear I've noticed a spot of that on my face in the morning 3 days after I've used it but it has also saved me so much time when maintaining things I've already worked on. Good show sir, I really enjoy your attention to detail, thanks for sharing.
