Just for the sake of completeness, when using a new holder in this situation i would have spun the ground bar and used a dial gauge at the bottom to check for run out, but that is just me being paranoid about modern kit which is often from the east even with a reputable name etched on it. 😉

You hit a home run in your statement beginning at the 19:54 mark by summing up what, even prior to my machining hobby, that I daily had to measure within my own self to deliver on time regardless of time allotted a working stable product of the time per day freely given by me to meet the requirements of my several jobs in the electric power industry (Up to & including 500,000 Volts & a brand new Power Plant that was given to me to complete & commit, electrically, to the system we call the grid) & direct it's very 1st test to prove it was capable of fulfilling it's given mission. Well spoken Sir & although I am happily retired, consider of the regular classes I'm afforded to learn from in this, your trade, my favorite Professor. I really can only sum it up thusly: "There is no-one I look more forward to for my next video for the inspiration to fight my chronic back pain just to get up from this chair & show some progress. Don't stop what you're doing, just as you're doing, the time to continue & the Good Lord allows. It makes a bigger impact on countless lives more than you can count or know.

Absolutely enjoy your content. Your shop is a far of dream of mine to have. Loads of thanks, from New Zealand. Always learning from you

[@greghare4226]

Your comments on the subject of "good-a-nuff" were spot on. As a retired machine shop supervisor this was a endless problem on both sides of the spectrum. We once had a job of building the "wishbone" for a three point hitch on a tractor implement. I knew I was in trouble when 7 Hrs. into a 2-1/2 Hrs. job I saw the machinist with a set of (very expensive) 36" dial calipers measuring a welding/fabrication job only needing a framing square and tape measure. Didn't make any money on that one! But it was dead nuts on. You have to use some judgment on what degree of accuracy is needed. Good job Keith! Keep it up buddy.

[@farmalltomf]

Keith, at 20:00 you speak about "good enough". I 100% agree with you. You match the effort to the required tolerances. Why would I hold a 0.0001 tolerance on a part that has a +/- 0.003 tolerance? time is money, and the extra effort and time it takes to get to that level of precision doesn't put $$$ in the bank. Braggin' rights don't put food on the table. Nice video!

[@b2gills]

If you do ever adjust the other part of the universal head, I would consider using a machinist jack from the bed to the casting to provide support for the adjustment. It would also work a bit like the worm gears in other milling machines.

[@sp1nrx]

I was wondering why he couldn't use the vise that's mounted on the table to resist the rotation of axis... but the jack is also a great idea.

[@alandaters8547]

Agreed! It could be under the furthest out part. Put in the jack just touching, then measure the height to the bed, then loosen screws-if it drops ("nods") at all just use the screw jack to bring it back to the original height.

[@KPSchleyer]

I was thinking the same thing, put it under the rod and turn it up or down. Also thought about loosing everything with the face mill installed and letting it sit flat on the table... then tighten everything down. Wonder how close thatd be...

[@b2gills]

@@KPSchleyer You wouldn't want to jack it up by the rod as it'll bend.

a big ole factory near me made shoe making machinery, actually they were the world's largest maker of such.

Keith what you could do to fix the problem with the head wanting to swing as you explained it to drill a center in one end of the bar, then use a ball bearing under it and support it with the table. and raise and lower the table to tram it that direction. Thanks

[@bulletproofpepper2]

Your absolutely right. I was making a part at work, the machinist was busy repairing something important with the chief mechanic. I thought the part was for that operation and was trying to hit all the marks of the dimensions. I later found out the part was for the welder and just needed to be in the close to the dimensions and welded onto something else and the machinist would finish machining it after. I could have roughly made the part into roughing stage and right shape and it would have worked better and easier. The machinist said if you don’t know ask. Thanks for sharing.

[@kitmaira]

I remember thinking “what the hell, why didn’t he tram the head” on that job recently, and I saw a few comments on that point. Thanks for the explanation on “good enough.” It’s now obvious that you were entirely correct on that application. I’ve learned enough to be dangerous watching KZbin machining content, but obviously the more I learn, the more I realize how much more there is to learn.

[@refactorear]

20:30 That hits home because as a computer programmer we also go into that rabbit hole, we sometimes spend so much time trying to make something perfect that it's not worth it. As you say sometimes it's just good enough.

[@jonathanrichards593]

Actually, it's always "just good enough" even if your best measuring tool shows it's dead on the numbers, because your best measuring tool was made to a tolerance, too. The machinist's skill and judgement comes into play in knowing the point at which chasing even more precision is pointless. I love to see the tools that Keith has accumulated over time - the Leaning Cylinder is a gem, and must have demanded some fantastic manufacturing.

[@TgWags69]

Use a machinist jack and some blocking to jack up the main head to control the rotation. That way you can loosen it up and jack it up or down until it is where you want it.

[@aaronfritz7234]

A wise machinist said “nothing you make will be perfect but the skilled machinist knows what is good enough”

[@sbroz1424]

Putting a ball bearing between the table and the bottom of that rod will allow you to use the up and down feed Of the table to aid in adjusting.

[@1crazypj]

That's how I saw it done in the 70's while I was training.

[@jamanjeval]

Wouldn’t a point contact like that risk putting a dimple into the table? Plus the bearing could slip out. Why not just use a shim of wood? There should be enough friction to even do the adjustment by moving the table.

[@1crazypj]

@@jamanjeval Actually, the guy I watched had a brass 'washer' on the table to prevent any marking from hardened ball. Point contact from ball makes lining up much easier for some reason but I don't remember why as I've never had to tram that type of mill

Two relevant facts I learnt during my apprenticeship. Man is not infallible so anything man made will never be 100%.

I work in Automotive manufacturing. Tolerance stackup is indeed a pain. Usually, the larger assemblies get a looser tolerance. And usually, the parts I work with being mostly sheet metal (body parts, etc.), there's some things than can be adjusted in the (sub)assembly process. Still, I have countless stories of being up the creek because I have two parts whose tolerances are near max and not in a way that agrees with each other... we find a way to make it work (and push back on the prior process/supplier to level it up), but aggravating nevertheless.

[@PhilG999]

Tolerance stack up IS a PITA! Years ago, I was a Warranty Engineer for a German Diesel Engine manufacturer. Suddenly we started seeing problems with one particular application. The engine was mated to a ZF transmission and sometimes the thrust bearings would go bad on one machine, but not on the next five or so. My boss liked to assign me tasks WAY above my pay grade (he took a personal interest in my development as a young Engineer, he was a 50-State PE. SO I did a tolerance stackup based on the factory specs of the engine AND the transmission and YES, in fact if the tolerances in the transmission stacked up the wrong way it "Preloaded" the thrust bearings in the engine! ZF was "thrilled" when we informed them...

[@edwinfriedl2446]

And with repair parts it only has to fit on one particular machine not any one of ten thousand machines.

Great comments on precision and what's required day-to-day. There's good, and there's good enough. Especially important in a production environment where time is money. I'm primarily a hobbyist woodworker and frequently work to a couple of thou, because I can. I would make a terrible carpenter.

[@walterplummer3808]

Good morning Keith. Ignore the peanut gallery. Thanks for the videos.

[@jackpledger8118]

Keith, Your discussion touched on tolerance stack up and reminded me of my 2 experiences with this issue. The first one occurred back in my Air Force carrier when I was to demonstrate the stall warning and prevention system just installed in our FB-111A fleet to a general officer. The demonstration began a altitude with pulling the power to idle while maintaining altitude and watching the AOA (angle of attach) rise until a set point where the stall warning should occur and the "stick kicker" push the flight controls forward to reduce the AOA. As we passed the AOA point where the system should activate, but noting happened. Upon investigation we found that everything was within tolerance and working properly. The tolerances were just all in the same direction and the "stacking" of the tolerances allowed the system to exceed the overall specifications. The second occurred when we were required to measure some specific points on our fleet of B-1B bombers at the base where I was assigned. We hung plumb bobs from specific points and took measurements for all of our assigned aircraft. We found that there was as much a a foot's difference in the length of our shortest B1-B to the longest due to tolerance stacking.

For a perfectionist, "good enough" is one of the hardest phrases to live out. After over 45 years in the cabinet trade, I'm doing better at it than I did back in the "old days". Chasing the elusive goal is mostly a waste of precious time. Good enough.

Interesting tramming technique, Keith. Seems very effective and fast. Going from precision tool and diemaker to outside machinist in shipbuilding called for a major mindset change. To be effective in any machining job you have to understand the real requirements for accuracy and not go beyond that.

[@andrewstoll4548]

The Russians have a saying about this. " Good enough"

[@robertlevine2152]

We built five tankers 272.69 m (894' 7.8") in length. Normally, the shipyard marks the centerline of the shipways or drydock before the start of assembly. In a large drydock, they may be building more than one ship at a time each with a different length and beam (width). Setting the centerline is critical. On one ship they set a bulkhead in place before establishing and marking the build centerline. The shipyard then determined the centerline of the ship from one side of the bulkhead looking forward and the other side looking aft. It was not until the official length, beam, and depth measurements were taken before the ship was launched that anyone realized the centerline was bent. The bow was 0.15 m (6") off-center. The error was not detected during construction. But, the cumulative error was measurable before the launch.

[@sbrunner69]

What is an outside machinist in shipbuilding?

[@robertlevine2152]

@@sbrunner69 Shipyards have machine shops which are responsible for machining parts such as propeller shafts rudder stocks, and rudder pintles. The shops will also turn the rough inside and outside diameters of bearings for the rudder and sterntube. Some shipyards manufacture watertight doors, while others produce their own propellers. The machinist in the shops are considered to be "inside" machinists. There is a second group of machinists that work on the ships, or away from the shops, they are referred to as "outside" machinists. The work they do ranges from aligning engines, gears and shafting. They bore the sterntube, rudder, rudder castings, and pintles to size for bearing installation. Outside machinists align machinery, shim and bolt it in place. They bore and fit tapered bolts used to hold shafts together. They are also responsible for fitting and installing hydraulically tensioned bolts. In general if the work is machinery related, and is done in the outdoors or on the ship it is done by the "outside" machinists.

[@paulkinzer7661]

'Perfection is the enemy of the good' is a very old maxim. I prefer 'Perfection is the enemy of the good ENOUGH' because it expresses the idea, um, more precisely. And, as you say, we all have differences in just when we think something is 'good enough'. I'll ask myself, 'Will it work just fine as it is?' Since almost everything I make or repair is for me, if the answer FOR ME is yes, then I'm done. On those rare occasions when I'm doing something for someone else, I try to go the extra bit of precision, even if I know they will neither know nor care, as long as what I do works.

[@JimSmith431]

With regard to Keith's discussion about tolerance and precision (at ~20:00), my pet peeve is when counted numbers and measured numbers are confused. You can have exactly three apples. That is a counted number. But you can never measure exactly 3 inches. Or weigh exactly 3 pounds. Or wait exactly 3 minutes. Those are measured numbers and are only accurate to some precision.

[@archbuilder71]

Commentary on the construction tolerances. As an architect, I run into the younger people not understanding that, kind of in reverse of what you are talking about. They miss the fact, that just because they can draw a 2x4 to exact dimensions in CAD, those don't exist in the real world. It takes them a while to understand what to be concerned about and what can be out a little bit, and needs to be in order for it to be done economically. You are working on a much finer scale, but same principal. I also like that you brought up the compounding error. In my world, if you get the foundation in tolerances and specs, the rest of the building process is smooth! Get it wrong and you spend all your time from then out trying to offset the error! Never a fun time or a good product. Its all about understanding the job and what the tolerances are.

[@jfl-mw8rp]

Well said Keith. In the automotive business we always check tolerance stack up in assemblies.

[@gregfeneis609]

I imagine, at some point after 7:37, perhaps off camera, Keith put a dial indicator on that shaft and rotated the spindle? I'm thinking, since it seems like it's a brand new tool holder, brand new precision silver steel shaft, and seems like they've never been combined on this machine before... And, Keith's about to perform a somewhat pain in the neck adjustment. It might be worth the extra few minutes to give the spindle a few rotations with a test indicator on the silver steel shaft to confirm concentricity, trueness, etc. Essentially qualifying the new tools to be used for tramming the machine with the old known-good tool (cylinder square). Anyway, just a plus up, if you will. Happy Thanksgiving '23, everyone!

For the axis that runs parallel to the table that is difficult to adjust because of the head being cantilevered: you could put a block of wood below the rod in the spindle so that it supports the head from flopping over and just enough under it that you could still measure with the cylinder. Then Use the table up/down to adjust it.

There's a book Called "The Measure of All things". The "Book" is about how the French tried to accurately determine the geographical location of various points on the face of the Earth. Using the best measuring instruments of the time they were able to locate very accurately the location of various Monuments, Cities and points of interest. However, as the project was nearing the end, the "Surveyor" could not pinpoint the location of a City in Spain (I think is was Spain). Later it was discovered, The reason was a build up of tolerances and personal error, like you mentioned. The Surveyor eventually went "Mad" because he could not reconcile the error. it wasn't until years later personal error was discovered. if Two People try and measure the same object the measurements will usually be very close but rarely be exactly the same. Just adding my two cents. KOKO! I miss ARW.

Pefection is the enemy of profit. Period. Your channel has become one of my favorites for this reason. Because I admire the fact that you don't let the income of your day job or other income sources skew your pursuit of precision. No offense to channels like blondie hacks and clough42, also great channels, but theiroutside income allow them the ability to chase tenths with zero worry of making payroll at the end of the week or getting a part out to spec by the end of the week profitably and it becomes a neurotic pursuit of those that need to. Robrenz, adamthemachinist, stephan, all step down their tolerances when they are making a refrigerator_holder_shutter gadget out of bent banding stock or a 3d print. Clough has the luxury of time to dial in his 3D printers, no different than grimsmo, to speed futute production. Makes sense but its a luxury not often afforded.

Going back 3 decades here, and I'm not sure what replaced it, or what subsequently morphed out of it, but there used to be a management philosophy in industry called 'Total Quality Management' or TQM. Which was an efficiency drive to better derive the specification requirement of whatever, and then complete that (say) part or work package to that spec, but no more, within time and cost restraints deemed appropriate, and no more.

Nice rant on precision. Just because you _can_ measure something to 10 decimal places, doesn't mean that you should. I once had an AM radio related application to the FCC rejected because they demand 3 decimal places of accuracy. The nice lady called to tell me that she was rejecting the app & told me that I had entered 5.0 amperes in one of the form fields. She wanted 3 decimal places. I finally convinced her that 5.0 was pretty close to the same as 5.000...

Considering the projects you frequently attack, the precision YOU attain FAR EXCEEDS the original specifications. Does a 100-year-old locomotive need 1/1000 inch accuracy? HELL NO!
