Extra Large Atlas Lathe Dials pt 1 TIPS #431 tubalcain

howdy once again is tubal-cain it's early in the morning and it's Coffee time and this video today is concerned with lays dials larger easy-to-read lays dials they're going to be a lot of talking there'll be 3d printing so this is just a fair warning for you people that do not like that kind of content so move right on to the second part of this video if you don't want to hear a lot of talking and about why I am doing this so stand by some of this content was covered a long time ago in tips number 89 where I mused on the size of lathe dials just a little bit of repetition here but you also could go back to watch that video if you were so inclined now take a look at these dials here this is a salt Bend lathe dial a real old one and these are Atlas lathe dials also real old ones from the older model ten and twelve inch but these are difficult to read now not for a fifteen year old boy in a machine shop class and South Bend lanes were often used in training but South Bend many years ago came out with larger dials and satin chrome dials because of the complaints and because of the old men that might be using they just can't read these little dials and as they get kind of corroded and rusty like this appala style that's really impossible to read and especially as your eyes age and you're looking through cataracts now you tell me which dials are easier to read here these large plastic 3d printed dials or the little old one-inch dial here on the south ban lace now this video again concerns 3d printing these were 3d printing and it's a collaboration a collaboration between myself and Kevin Chompy from the garden state of New Jersey who have helped me in other videos and has continued to help and he did all of the the CAD work on those and sent me the file so I'll talk more about him later but I thank him very much for the help I could not have done this by myself I do know how to 3d print but I am a CAD person whew fusion 360 or whatever it is that Autodesk Inventor rather is what Kevin uses so thanks Kevin let's move on here now now I'm standing in front of my Logan lathe and a couple years ago I made videos and here they are if you have not seen them and have any interest at all and watching them but I did make larger lathe dials at that time for the Logan lathe this is the original one and this is larger than what you see on the Atlas lathe or what I showed you there a few minutes ago and I increased it to this size and this was the largest size and that's aluminum and it's machine that is not plastic but that was the largest size that I could put on this machine because there is interference here so even at that point it strikes I did not deal with compound dials in today's video or a long time ago because most of our problems here and our our settings on a lathe are with the cross feed dials I'm going to talk about the dials on several different layers here so a move ahead if this is too boring for you but this is my 12 inch Atlas craftsman lay and it does have larger dials here again is the older dials as some of you may have on 10 and 12 inch dial a is made in the 30s 40s 50s and maybe even early 60s and again that's about one inch whereas these dials are about one and three-quarter inch not that hard to read other than they are not sat in chrome and they are not direct reading which I'm going to address here in a minute so this is the lathe that these dials are going to fit and I'm going to get into that in great detail here but let me talk a little bit about direct and indirect reading dials and I'm going to step over to the clausal 12-inch lathe right now these Clausing dials are wonderful they are 2 and 1/2 inch in diameter and that is the diameter of the dials that I may for the Atlas lathe remember Atlas and Clausing are really one in the same company or were when in their heyday I'm not so sure right now but not only are these dials large and easy to read but they're also satin chrome and that also facilitates reading of the dials now let me talk about direct and indirect reading dials and these are direct reading I have to digress a little bit now again this is the South Bend compound this is Atlas but all of the screws used in every brand that I've ever seen including the Clausing and the harder in a few in the Logan that I have here in my own workshop are 10 threads per inch 10 threads per inch now what's the significance of that the significance is that that means that the pitch is one hundred thousand or one tenth of an inch therefore for each revolution full revolution the the tool is going to move one hundred thousandths that's an important concept to remember now in what I'm talking about at this point in the video I need to try to explain the difference between direct and indirect reading dials on this again is the Atlas lathe and I've set the cross feed here at 0 and I have also in place a dial indicator set to zero so just for illustration here I'm going to turn the cross slide one full dial which is one hundred thousandths so looking up at the dial indicator you can see that I have advanced the indicator or the tool into the work by 100,000 but that's by doing so it actually removes 200 thousands from the work if I was actually cutting a piece of steel so it moves in 100 takes off 200 I call the in direct now some people may call it radius reading or diameter reading or have other terms for it but that's the terminology that I'm using now let's go over to the closing and see a direct reading dial at the Clausing now these are direct reading dials so this dial if I've turned one full revolution as two hundred thousandth and also have an indicator in place here so while just watching the indicator here I'm going to advance a half a revolution down here on the cross V which is one hundred thousandths and watch what happens on the indicator come a little bit past so I've only moved 50 thousandths see half of a revolution here therefore since I moved to one hundred thousandths is going to take off one hundred thousands it moved in actually only fifty thousand says that clear as mud so in review since all lathes are using ten 10 threads per inch on the screw you're going to see a difference here on the dials where some of the dials have the graduations real close together like this one and it reads up to two hundred thousand and the other they're a little bit farther apart and it only goes to one hundred thousandths so that's how you can quickly determine on your machine whether they're direct or indirect just by how close together the graduations are or how many thousands are indicated here 100 or 200 let me take you over to the Hardinge lathe and show you something interesting on that machine now remember this little Hardin's leaf is called a speed lay there are second operationally so it has no tail stock it has no carriage really so we have two dials here and these are nice dials because they are plastic they're easy to read they're white with black numerals and lines on them very easy to read but the one on the cross feed here is direct reading no it goes to 200 thousands however the dial here on what I'm gonna call the compound is indirect only 100 graduations because in fact here we use that we need the the 100 thousands in other words if I feed it in and this is longitudinal feed if I feed it in 100 thousand I wanted to actually move 100 thousand swear on the the cross slide we're taking a certain amount of material off of each side of the work so that's why they built this lathe with two different dials even though the screws are both 10 threads per inch so i bloviate it quite enough now on the difference between direct and indirect and 100 and 200 graduation dials because in fact for the Atlas lathe the craftsman lathe I intend to make dials both 100 and 200 graduations so now we're actually going to get on with the video thanks for sticking with me if you have back at the Atlas craftsman 12 inch late I'm going to take this apart now to show you how I actually went about this and I've already loosened up this nut here so that has to come off as well as the zamek handle and then there's a key I can get that out alright I got the key loosened up then there's a lock washer the star type that seems kind of crude now this is a fine thread that takes a minute or two to get off now that's really all you need to take apart now there's a little brass pin here don't lose that and this can be set aside I'm not going to throw this away this will be attached to the lay there for the next owner but the diameter right here which is three quarters of an inch to fit into the new dial one other thing that I needed to do was to enlarge the diameter of this piece with a new zero mark so I made it out of aluminum but of course it could be printed but this probably was made in 15 minutes printing this would take a lot longer because I'd have to have Kevin or somebody do the actual work for me and then print it out would take a couple hours so it was much faster to make this just out of aluminum and I then will put it on here and I had a real nice fit I'm not going to put it on now but a nice press fit where I could just tap it into place it could be held on there with Loctite or little set screws as well but I lucked out here and I worked accurately enough so that I can tap it on with a little of lead hammer when I'm ready and that will give me a reference point see there are zero mark now let's talk about printing these you may recall that some time ago kevin champey contacted me and i made a video of the dials he he made another one of these that was 3d printed this is the steel one but there's a 3d printed one that he designed I think taking it off of this and he sent me information on that and we printed out or I printed out several dials from his files and we did them he designed them several different ways and these are kind of hard to read but some of them with raised dials and some of them with recessed dials like this so we were experimenting and eventually he came up with the perfect solution and size and and the depth and all of that and it was a great improvement over what I'm showing you right here there's one that's raised but you can't read the graduations at all so let me show you some of the ones now that I 3d printed there were several different trials here in abate various depths or this is one of the with raised numbers and graduations can you see that but there was no good way this is hard to read there's no good way to ink this other than maybe to put it on a stamp pad but I think that would wear off so decided not to use this although it amazed me that the 3d printer was able to do that but you can see it isn't real easy to read so pretty much scrapped that idea and came up with the recessed and that those are filled what I'm going to talk about how I colored those here in a minute but don't you agree that that is very very easy to read and that's the 100 and there's the 200 also very very easy to read that one was 30 percent fill so I experimented with that but it took a long time to print these out that one was twenty percent and I didn't mark them all but eventually decided that the amount of fill wasn't that important twenty or thirty percent is it's fine now he also printed the whole we did several different versions of that even trying to print the thread but that didn't work out so it's just a straight hole and I tapped at 8:32 I forgot what size that was but that's how it printed out tapped at 8:32 and I'll be using these little thumb screws along with a little brass rod that'll press up against that piece so it can be loosened and then locked I didn't like this green filament at all and this is PLA not ABS this is the 200 graduation raised it's amazing how that printed out but again I'm not going to use it you you
