Lathe Spindle Pulley Repair 

❤😊

Get ahold of some ring gage standards and practice making measurements with a telescoping gage and micrometer. Then you get a really good sensitive feel for the telescoping gage. That and a mike are very simple yet very accurate inspection instruments. They can replace far more expensive bore measurement tools like digital bore gages or Intramikes.

You can't teach touch. Practice!

You may want to calibrate your micrometer to your own personal feel as well. Most shops I've worked at either calibrate tools for the machinists or require you to use their instruments.

Same thought, is not just a repair, I mean it is, but it's also an upgrade, because is gonna slide super nice!

A repair like this also allows you to keep replacing the wearing parts, adding years to the life of the part. At United Airlines, I maintained maintained large gearboxes and handing gears with incredible close tolerances using spray metal, bronze bushings and very similar procedures. We used not only lathes, but also CNC boring mills and manual horizontal boring mills. We were constantly reminded that the components we worked on were worth up to 1/2 million dollars. We were never rushed to get things done fortunately.

So you're basically saying that machinery can be fixed or repaired if something goes wrong, but your body can't. Is that it?

@@1LEgGOdt A GIFT FROM G. O. D.

Maybe throw some videos up on your channel?

@@1LEgGOdt No, I think he’s saying that eyes and ears and brain all working together create what is commonly known as the “magic touch”.

@@ellieprice363 Nah, that is possibly just a mind polluted with a lifetime of abusive religious indoctrinations trying to say that he has expertise[1] ... which is really fine. We need such people who can do things. Correct is that eyes and hands and "everything" is nothing worth without appropriate measuring devices and the knowledge how to use them all together (In fact eyes and hands and all skills that our brain provides "out of the box" are the worst possible set when it comes to technical accurate tasks. That is WHY special devices exist to HELP us. Believing(!!!) otherwise is just a very strange thing, as "believe" wont keep tolerances. Only reality and (material-)physics will do so.). He may be a good machinist but also a bad communicator or teacher at the same time (which isn't unusual or something bad ... totally different skills are needed). This also explains the use of that vague language like ""the touch" and "something you can't explain!", which actually means something HE can't explain (either by the lack of skill or the lack of words ... or to keep it a myth, to ride the narrative). Also: every profession has tendencies for myth-making, trade secrets and internal jokes. There is nothing wrong with it and that is also were we come back full circle: We are humans, and thanks to people like Adam and Phil, we are not that boring like a box of measuring tools;) [1] read further: or it is just FUN ... some kind of:) "commonly known as the “magic touch”" ... the whole point of something magic, or magic itself is that it is NOT commonly known, only to a elite circle and surrounded by myths and marvel that themselves create admiration in the "uninitiated". In other words: Made up fibs and other fairy tales:) You have to know the MEANING of the words when you use them ... Also it would make no logical sense, because magic demonstrably doesn't exist, but only as illusion, and you can learn the mentioned skills of those trades in schools and from other people. This is done frequently to the millions all over the world, even other hominids do it (demonstrably!) and is in no way magical or for an elite circle of people. What we have to admit is that vague terminology like “magic touch” can mean everything and nothing and additionally for every different person something they think they "know" ... and for the next one: the exact opposite:))) So it is really useless when describing something to another person, besides you want to confuse them (with the ... I don't imply this!!! ... very very very unlikely possibility that the reason for the use of "magic" or the-like vagueness is that the speaker/writer is confused himself, hehehe). Problems: There is that kind of people who are attracted to the unknown and therefore get interested and learn that trade. But others can't see so far and don't get even a grasp what it is about and that they are able to develop the skills for something such "divine" in the future. They are lost for the profession. My opinion is: Yeah, have your jokes and "pirate talk" (you landlubbers! Hehe) as long as especially kids and all people get in contact with the opportunity to learn such professions, f.e. in schools or at local institutions. We need experts and experts who teach their expertise to the next generations (I am not saying that they are not allowed to make fun, or have no right to be strange contemporaries ... that is just not their expertise, you get it?!). What is very tragic is that the profession, who really has expertise in myths and magic (like authors and script writers) has a big problem with exactly that knowledge transfer. That is in part a reason why there are only a few outstanding "magicians" with "the touch" to fascinate millions with their writings or screenplay. But that is a totally different story.

Yeah really good!

Adam probably asks himself: ' On a scale of 1 to 10, how good will this job be for the channel' before he decides to take it on or not. I wonder if he also has a scale for ' Could this be the customer from hell?', though I suppose if you were a Patreon, it might help.

It was beautiful work that would not be affordable to have done without it being good for RU-vid. The bushing work by itself MAYBE if the rest of the machine was a peach, but the spray weld repair AND the bushing? You'd be wondering why you aren't replacing the machine. Or ordering/having made a new spindle shaft. As he said at the end "A good repair and provide some content to the channel." Nice to see frankly. Even if the customer paid pretty solidly for the work, still worth every penny.

...SMALL JOBS LIKE THIS ARE GOOD FOR FOR HONING YOUR SKILLS- BECAUSE "PRACTICE MAKES PERFECT"- AND YOU MIGHT LEARN SOMETHING NEW!!!

Did Adam say somewhere that the client wasn't charged?

Customer probably paid for this job. I actually had Adam look at a part for a flame spray repair and received a quote for it, wasn't expecting a free lunch

might be a good idea to get the bushings done before the shaft gets damaged

@@ThePirateGod that's kinda what i was thinking haha! Except i only have one lathe, and if i was to take it to a shop, they would charge upwards of 400$ for this :(

@@analog56x email Adam and see what he'd charge or just try to rent the use of someones lathe and do it yourself.

@@ThePirateGod i would totally do it myself haha, unfortunately, I'm the one everyone comes to for machine work if they don't feel like paying the 150$/hr that shops charge. I have made pretty good friends with one of the local machine shops, so maybe i could chat with them. In either case, i should definitely look into it. I might be moving my lathe here in the next little bit, and that requires teardown to get it out of where i have it now haha. I'll inspect everything and see how its lookin :) might be worth emailing Adam too, but i think shipping might be the killer, as I'm up in canada-land haha

@analog56x Yeah, I hear you. Shipping insane up here. I'm in Northern Alberta.

Noooo! There's too many loud and annoying transitions on RU-vid, and more and more everyday. You only add these noxious transitions when you don't have any good content. Abom does it properly.

Adam always love watching your program. As a retired long time tool and die maker I am surprised you wear a watch while on the lathe. Was always warned watches and rings were a no no around machinery. Safety is number ONE. I like the Flame Spray Build up on the spindle body. You are always coming up with great content! Thank you

What would speak against using a piece of actual glass? I know, if something goes wrong you get a lot of shards, but it won't scratch much. Maybe this safety glass that doesn't break into sharp shards but tiny cubelike pieces? Or another idea: put a screen protector for tablets on that plastic, so you can easily swap it out if needed. Those are pretty scratch resistant too I think, might be worth a shot, there's propably one out there in the right size.

@@CatNolara Glass is not suitable because it will scratch, and all of little glass pieces will imbue lathe guides and wear them down a lot faster

@@CatNolara The issue with "Safety glass" is that it's under strain - due to that 1 sharp chip impact can lead to it actually shattering easier in some cases than normal glass that would just chip and be otherwise fine - Plastics on the other hand are maleable and give when impacted far better than glass Tablet screen protector is essentially the same idea as my suggestion - the reason I'd bias towards the sand blaster supply is you can talk to a supplier and get a hundred or so cut for pennies on the dollar to whatever size you want

I was going to suggest this, thought the same but wonder how expensive replacements are. Is it worth it?

@@RyanDoesAll Personal decision on that point - As mentioned you should be able to get them for a few cents per sheet - They're a weekly consumable for a sandblaster that is there to protect the actual glass behind it

That is a good means of chip control. If you're using a screw on chuck, consider that you can unscrew it, cutting in reverse under heavy cuts. A student did it in school once. Not pretty, but a good 'learning experience'! It could cause a serious accident though. Fortunately this was only a small 10 pound chuck. But most likely it wasn't the first time that ever happened. Also consider that a normal left hand boring bar or internal threading tool, tip turned 180 degrees, will cut on the opposite side of the bore but still using the regular CCW rotation.
