 Greetings and welcome to what I believe is part six of taking apart the Monroe Model K calculator. So during the break I was looking at the sides and I thought we would maybe go through some of the levers to see maybe what they do. This was the bell muting lever, so you can see that it basically has a spring and it's got two little resting spots. So essentially it has two positions and it can sit against the bell to mute it, so that's that section. This thing, I have no idea what it does. That gear, I also have no idea what it does. Maybe when we put it together we can figure that out. And then there's this whole thing. So you remember that this lever was connected to a crank on the, let's see, what was it? Yeah, on the Leibniz axle. So it would go basically like, it would go around in a circle like this, back and forth like this. Now this thing over here, if it weren't actually held by the wire, or maybe, yeah, if I move this, this lever actually locks this in place. And it would actually prevent the Leibniz wheel from moving, which I believe would basically lock up the entire mechanism. I'm not entirely certain what that's for or why that would be, so that's how that thing moves. It's kind of a weird mechanism. Again, I'm not sure if this wire was meant to be here, this wire here or not. One thing that I do know is that this over here actually is a sort of a rubberized pad, and it was meant so that when this lever banged into it, it wouldn't have so much of a shock. So maybe when we put it together again, we can sort of see a little more clearly what that mechanism is supposed to do, what exactly this was supposed to attach to. If I look on the other side, this whole, that lever is connected to this axle, which on the other side is connected to absolutely nothing. I think it's actually connected to something in the automatic version, but it's not connected to anything in the manual version. So, round and round and round, let's see. That's about it on this side, and then on this side, we had the, this was the zero button. When you pressed it, it popped up all the keys, and then this is a repeat and a non-repeat. So, clearly it has two positions. It's essentially a toggle switch, and there's this thing, which I'm not really sure what relation it has to these two gears. This is the crank gear, so it's the main gear, and we went over this lever before. And then there's this intermediate gear, which actually has a small gear inside, which turned the Leibniz wheel. And I think that just about does it. So, I think the plan is going to be, let us attempt to separate the two sides of the frame. So, we've got several things that are holding it together. So, we've got the front bar with pins in it, and these pins were for the keyboard rocking bar things. There's a screw here, another screw on the other side, so we could take that off. So, this axle in the middle, I believe, can probably be removed, because there is a cylinder thing over here with a set screw. So, I think if we loosen the set screw and move this, and then this is a spacer, and the spacer can slide, and then we can just sort of slide the axle out. I think that's probably how we can get that out. The bottom part here, I think this just screws off these two parts. And finally, we've got this central member over here, which appears also to be probably held in by screws somewhere. So, let's go ahead and start to unscrew these things. We can probably just get away with unscrewing one side and then separating it, and then we can unscrew the parts from the other side. So, let's see. I did not set the timer, but I do have a watch that I'm watching, so let's get started. So, we will unscrew this screw first. So, let me start another bag, first of all, so that I can bag the parts immediately. So, this is bag eight. Bag eight, seven, seven, three, three, nine. Alright, so the screw comes off. Again, it's a screw that's partially threaded and then not threaded. It's an eight-thirty-six. The length is point six-two-five, which is a nice, even five-eighths of an inch. And it goes in bag eight. Okay, so that's for this bar. Now, for this axle, what we're going to do is, let's see. So, first of all, are all these levers connected to anything? So, there's this, there's this, which is where the axle is. This sort of hooks on here. I guess I can unhook it. And I don't think it's actually attached by springs or any other levers to any other linkages or screws or anything. So, I think we can just go ahead and remove this set screw right over here. We are going to have to use a small bit for that. So, what I'm going to do is I'm going to loosen the set screw. Okay, that's not actually working very well. Ah, there we go. So, I'm going to loosen the set screw. And then, now I'm going to have to slide this part over. And usually that is a bit of a pain because it's usually been on there for so long. So, I just sort of twist it a little bit. Now I can move it. See? Okay, and then I can probably, can I move the spacer now? I can certainly pull on this. It's a bit hard to move. I wonder why that is? Why is it hard to move? Is the lever connected to anything? Okay, well there is a spring on this side. Okay, so I'm just going to unhook that. Alright, that will make things a little easier. Let's see if I can just pull. It seems, it seems tight. It's kind of hard to move, almost as if there's maybe, it's either too tight or there's maybe some partially solidified or congealed grease in there. But other than that, I really don't see anything else. There does appear to be, okay, so this appears to be oil that has partially congealed because it's not quite the consistency of molasses, but it's pretty close. So that definitely needs to be cleaned. And that probably goes a long way towards explaining why this thing is so hard to move. So I'm just going to try to maybe pry this out a little bit. See if I can pry this part out. Yeah, see it's coming out. It's just really kind of sticky. And again, I'm not going to take it out all the way. I don't want to damage any of these parts really. So I'm just going to take it out just enough so that it clears the other side of the frame. That's probably good enough because then at least the frames will be separated and then maybe I'll have more room to work with. Okay, so now there's this central member right over here which has the other bunch of pins that the rocker bar is sit on. If I look at it from the underneath, there is the tip of a screw, right? So there must be a screw on the other side. This appears to be a leveling screw. So if I turn it over and we look here and here, I think the keyboard assembly actually sat on it, so you can actually adjust the tilt of the keyboard using that. So that's an adjustment that when we put it together we want to take a look at. So anyway, so there would be a screw on this side. That must be the screw over there, right over there. So I'm going to remove that. I'm going to change out the bit to a bigger one now. Unscrew that screw all the way. Okay, there it is. And this is a 1032 screw. And it's 0.625 bag 8, all right? So that's that. And then finally there's this, which appears to be just probably screwed on, so I can probably take my wrench and loosen it. Okay, is that a nut? I mean is that a washer? It is indeed a washer, so that's important to know. So there's a washer. The washer is in outer diameter 0.440, and thickness it is 0.032, and in inner diameter it's 0.246. So okay, so that appears to fit on this axle. So I'm just going to bag these in bag 8. And now, in theory, I should be able to separate the frames carefully. So let's see, can I separate the frames? Well, okay, this end of the frame seems loose. In terms of this end of the frame, I think there's actually a pin. Oh wait, nope, there's another screw. I have to remove this screw. So let's go ahead and do that. And apparently this thing, its only purpose was to hold the bell in the right position. And actually there is, plus there is a hook here for a spring that went over here, which I guess was for one of the assemblies that we removed. And this is one thing where good reference photos really help, because when you're taking, say, springs off of hooks, you take a picture of the context in which that spring was. And that can really inform you later on what the purpose of that spring was. It really, of course, helps when you put the thing together. So this is a 1032 screw. Its length is 0.627. So that goes in bag 8. Now I can remove, or can I, can I remove this? Yeah, it's kind of, it would be easier if I removed this part too. So let me remove that part. It's connected with a spring down here. So I'm going to have to unhook it from its post on spring. Almost there we go. All right. And now I can unscrew it. There is no nut on the other side of the frame. So I will unscrew it from the frame. Screw, uh-huh, lever in this orientation. And then there is a tiny washer with a little shoulder on it, which this lever sits on so that it can pivot. And then the frame. And so what I can do is pop these. Oh, I need to measure this screw, of course. It's 1032. And it is 0.437. So that goes in bag 8. And I'm just going to measure the outer diameter and thickness of this part. 0.344 outer diameter and thickness 0.121. So that should serve to uniquely identify the part. Now I can finally take off the bell thing. And you can see that it actually has two hooks on it for springs. So I'll put that in bag 8. Okay. And that means that I should be able to at least check that this is loose. And it certainly is. Okay. So, okay. So we've got this part loose and this part loose. So now there is this part, the central axle, which should be loose by now. But let's also pry at the front. Can we pry at the front? Is there a place we can pry? Not really. I should be able to maybe think I can probably fit the dental pick in there. Yeah. There we go. Okay. Now that is loose. So the only thing holding together this thing is friction. So let's go ahead and gently try to pull this thing apart. It's really the central axle that's being a pain. Can I pry at it somewhere here? Can I pry from this other side? Yeah. Just a tiny bit. Okay. Maybe what I can do now is pry a little more. There we go. Okay. Now it's out. Yeah. That is really, really sticky and that is no good. Okay. So there we go. We are now separated. So there's that part. This is the really sticky part. Oh, wow, that is so sticky. That's not good. So there is this part of the frame and this part of the frame. So what I'm going to do is we set that aside. So this part of the frame, I'm now going to remove this bar, this bar and this so that I've got a flat frame to deal with instead of this three-dimensional thing. As before, there's a screw over here, which I will remove. And this screw is an 836 screw. And how long is it? 0.629. Put that in bag 8. And now we should just be able to remove this. So orientation, again, is important. You can see that there is less distance between this pin and the end of this side and this pin and the end of its side. So it's important to note that this is the right side of the machine, which has the large gears. So you can't put it in that way. Well, you can. And that would be bad. So you have to make sure that it's this way. In addition, there are these screw holes here which face up. If you put it in the wrong way, the screw holes face down and you won't be able to use it. So let's deal with this axle. That's easy to remove. So it has another of these nuts. And because this looks similar to the other part that we removed from the other side, you should note that the other side was bigger. See? So this came off of the left side. And this comes off of the right side, which we will simply... Oh, okay. So the axle is turning. There is another washer. What I'm going to do is... Yeah, okay. So here's this washer, right? We had a washer on the other side. We need to make absolutely certain that these washers are identical. So this is 0.41. So I'm going to set this aside. I'm going to find the other washer. I'm pretty sure that this was a... Uh-huh. So you see this actually has a bigger inside. And the reason for that is that this is thinner than this end. So it's important to note the orientation that this is on the right side of the machine with the large gears. And this is on the left side. So the washers are correspondingly sized. So that's good to know. And finally, we have this central member. So it looks like there is a screw holding it on here and another screw holding it on there. So to get at the screws, we're going to need to take this gear off. So this is probably going to be fairly easy. The first thing that you should note is that there is a retaining clip. And this is the sort of retaining clip that you would normally use a C-clip. So basically, there's a special tool that is kind of like pliers except they're round. And that's specifically to remove those retaining clips. So instead, what I'm going to do is I'm just going to pull on this. It's basically springy. So I should just be able to pull on it and get it to release somehow. There we go. There's the clip. So clip that too will go and bag aid. And the gear just comes right off. Ah, a washer. That's really important. Now, here's a washer. Let's make sure that we don't mistake it for any of the other washers. So I'm going to put it over there. I'm going to measure the outer diameter. It's half an inch. If I look at the other one, see it's smaller. The outer diameter on that one is .438. So that's important to note. Anything else? Nope. This appears to be all one piece. Are we sure that it's all one piece? Can we pry this gear out? No, it doesn't look like it. It really does look like it was made. Oh, I see. There are weld marks here. So this actually was two parts. There's an arrow, which is a timing mark right over there, along with the two arrows on the outside, which are for the bigger gears. So presumably this arrow corresponds to something on this other side? No? Well, actually. Remember that the Leibniz gear, the Leibniz axle actually sat over here. So presumably there must be another timing mark on the Leibniz wheel. So let me go and get the Leibniz wheel. My microphone came off. All right. Here's the Leibniz wheel. So indeed, there's the timing mark right there. So that tells us that when this is put together, that's how it must go. Cool. All right. So I can set this aside. And now we have the two screws that we must remove. Or is it this one? No. It's this one and this one. So let's go ahead and remove those. The large screwdriver seems to fit pretty perfectly. So I'm just going to use that. And this is a 1032.618 bag 8. And this other screw here. Is this being so difficult? There we go. Screw 1032.618 bag 8. And now we should just be able to remove this by gentle prying. Because there's actually, I think there are pins actually here. There's another pin over here. So the pin is a bit tight. Those are alignment pins. So there we go. See, these are the two alignment pins right over there. So nothing loose on here. So we can set it aside. This is apparently made of cast iron. And part of it was milled. You can see the milling marks on the top. And if this were cast, that means that there should be a separation line somewhere. But I don't really see it. So, I don't know. Anyway, yeah, this is the sort of thing that would be kind of expensive to 3D print. I'm sure that most of the detail on this is irrelevant. And was probably only done to make it lighter. Well, okay, I guess that's not irrelevant. But these holes were put in because why have all that extra weight in here? Okay, so we've got this frame now. And we're just about at 34 minutes or so. So I'm going to leave it at that. We've made some pretty good progress. So we've got the frame separated. We've got some parts pulled off. And I think we'll leave it at that for this video. So, until next time, bye.
